Deforestation in New Zealand has led to increased soil erosion and sediment loads in rivers, adversely affecting aquatic ecosystems. Soil conservation actions over large areas are expensive and need to be targeted to obtain maximum benefit for least cost. Medium-complexity models of soil erosion have been used to target soil conservation, but they involve long-term averages and do not involve time variation. In this paper, an event-based model of soil erosion and sediment transport is developed. It has moderate complexity and is able to be calibrated with a modicum of data. The spatial framework is based on small subcatchments and stream links. For each storm event, the sediment yield for each subcatchment is estimated from peak storm discharge with a power function and routed through the stream network. We run the model on the Manawatū catchment in New Zealand for which all the major tributaries are monitored for water and sediment discharge. Spatial maps of sediment yield are produced for each storm event in a 5-year period from model inputs of maximum storm discharge at the tributaries. To test the model, predicted sediment loads of the storm events in the main channel of the Manawatū, at Teachers College, Palmerston North, are compared with measured sediment loads. The strong agreement between predictions and measurements suggests that the method for converting maximum storm discharge to sediment load at tributaries is robust. Analysis of the sediment concentration and discharge records for storm events revealed that sediment from channel resuspension and bank erosion was much smaller (typically <5%) than total storm sediment loads and could thus be ignored when routing storm sediment loads. The demonstrably small channel resuspension and bank erosion, relative to storm sediment loads, enabled simple routing from subcatchments to construct an event-based model at the catchment scale.

Abstract Deforestation has been widespread in the Northern Albertine Rift Landscape in rural Western Uganda. In this paper, we present perceptions from local residents and narratives from key informants on causes of forest loss during a 30-year period between 1985 and 2014. While the generic drivers we find are consistent with previous literature, we suggest that the specific context in which forest cover is lost in rural areas is path dependent, and this is vital for adequate management. In the Ugandan case, the history of the sugar industry and its relation to local political drivers and international considerations (e.g. biofuel) are prominent. Global drivers of forest loss therefore mask local-level complexities, but an amalgamation of local-level dynamics does not necessarily sum up to larger-scale manifestations (in a linear manner): striking a balance between understanding local-level and large-scale dynamics could be key in addressing the deforestation conundrum. We surveyed 263 households in 7 parishes around Budongo and Bugoma forests, and conducted 22 key informant interviews. Our findings indicate that the drivers and mechanisms of deforestation are local; they also vary between Budongo and Bugoma. Key amongst these include: agricultural expansion (28%–58.5% of the responses)—with large-scale commercial and small-scale subsistence farming significant around Budongo and Bugoma respectively; "poverty" (26%–76%) often alluding to heavy dependence on forests for livelihoods. Others include: population growth driven by dissimilar migratory patterns; and moving protected forest boundaries. Our data suggest that a combination of both local and key informant perceptions is instrumental in filling data gaps where a dearth of information is prevalent (especially around Bugoma forest), and is important for corroboration of other scientific data (e.g. remote sensing). However, a survey of wider literature indicates that there are significant issues missing from their stated views. While the continued expansion of cash-crop farming and lack of inclusion of local people in forest policy continues to raise concern, the stability of protected forest (i.e. Budongo and Bugoma) is encouraging and suggests a refocusing of the forest debate on practical working schemes for forest preservation and recovery might be the way forward for sustainable forestry and livelihoods. Highlights • Global drivers of deforestation mask local-scale complexities. • Drivers and mechanisms of deforestation around Budongo and Bugoma are local and varied. • Comparison of forest loss between locations reveals different migration and agricultural dynamics. • Debate about forest loss might benefit on a refocus towards what works for forest preservation and recovery.

Given that Land Use and Cover Changes (LUCC) and deforestation are activities with the highest anthropic intervention on ecosystems and increase the loss of biodiversity, this paper explores the LUCC and the main drivers of change in Andean mountains, taking a rural area located between the municipalities of Montenegro and Quimbaya (Quindío, Colombia) (1954–2009), as a case of study. Aerial photographs and geographic information systems (GIS) are used to create maps of LUCC, as well as a systemized search of information on LUCC and main drivers. The results showed that pastureland presented the largest area during all periods, occupying >60% of studied area, while the secondary and mixed forests had a contraction from 23% in 1954 to 9% in 2009. The change rates evidenced a greater affectation for the secondary forest that lost 86% of its initial area through deforestation and transformation processes, while crops gained 410% with respect to their initial area. As for the transition matrix, about 27.8% of the study area presented transformation from land use and cover into other land covers, 14.7% presented deforestation and loss of land cover in their initial area, and 57.5% remained unchanged. It is concluded that socio-economic factors such as livestock farming, agriculture and market prices have been an important driver in the modification of the landscape. [ABSTRACT FROM AUTHOR]

When agricultural commodities are traded globally, consumer demand in one region influences the crops planted in another, often leading to widespread environmental and social transformation at the production sites. As a commodity crop that prospers in tropical environments, oil palm has become controversial for its role as a driver of deforestation and social conflict, especially in main producer countries in Southeast Asia. As suitable land for oil palm production in Southeast Asia is depleting, companies have begun to look to new production frontiers, such as Latin America. Colombia and Peru have the highest percentage growth in the sector in recent years, and the crop has become a dominant strategy for development in the Peruvian Amazon. Between 2000 and 2015, 40,000 hectares of old growth forest have been cleared for large oil palm plantations in Peru. Company-Community partnerships (CCPs) have been advanced as a potentially more socially and environmentally sustainable strategy, through their alleged capacity to provide greater productivity and more efficient land use on smallholder farms. This paper describes the social, political and deforestation impact of an oil palm CCP at the forest frontier in the Peruvian Amazon. An interdisciplinary and mixed methods research approach was employed, including long-term ethnographic work and visual measurement remote sensing of land use change on 2447 hectares of smallholder land in four villages/communities. The results show that the recent arrival of powerful private companies has caused a major socio-ecological shift on the ground, particularly through the CCP. On comparing participating farms to non-participating farms, we find significant deforestation 'spillage' out of the plantation into participating farms. A major underlying driver of the negative outcomes of the CCP is the neoliberal policy approach employed by the Peruvian government, which has outsourced basic rural public works to private companies. We conclude by discussing how a more socially and environmentally just oil palm production strategy in Peru and elsewhere might look. [ABSTRACT FROM AUTHOR]

Abstract Understanding of the often complex forest cover change drivers, and the perceived and observed forest cover changes substantially contributes to the sustainable management of tropical forests. This paper aims at developing an integrated view on tropical forest cover change and its drivers by combining the perception of the stakeholders (farmers, forest guards, and forest managers) and five decades forest cover mapping, based on interview and remote sensing respectively, through a case study in the central highlands of Ethiopia. Afforestation and deforestation occurred when law enforcement was stronger and weaker respectively, depending on political regimes. Since 1937 i.e., the early Imperial period, the position of the forest edge has not changed much over time, it rather became sharper. In the late Imperial era (1972–1975), the forest cover declined only by 1.6%. In the subsequent two governments, the socialist and the current federal rule (1975–2014), the forest cover increased by 17%. There was a 3.9% forest cover decline during the transition between the two governments. This pattern of overall net forest cover increase observed by remote sensing data has been correctly perceived by stakeholders. Stakeholders acknowledged the observed forest cover increase, however, they argued that the forest is declining in terms of its quality for several ecosystem services (ES). The ES decline is believed to have resulted from the gradual shift of pure dense indigenous forest to an increasing share of exotic plantations. In the three political regimes, land policy, illegal encroachments, population pressure and social unrest have been the leading drivers of forest cover change. Communities' involvement in forest management activities and sharing benefits were regarded as positive perception of forest management strategies during the federal administration (1993–2007) of the current government by farmers. Among the factors that determine forest management strategies proposed by stakeholders are gender, landholding size, education level and age. Future conservation and development interventions need to consider stakeholders' concerns. Their involvement in forest management is also necessary for improved biodiversity conservation, ecosystem service provision, and social wellbeing. Highlights • We studied observed and perceived forest cover change in a forest conserved since the 16th century in Ethiopia. • Observed net forest cover increased between 1972 and 2014, which was correctly perceived by stakeholders. • Though the forest cover increased, stakeholders informed that the forest is, however, undergoing loss of ecosystem services. • Periods of forest cover increase do not necessarily coincide with periods of effective forest conservation. • Future conservation and development interventions need to consider stakeholders' concerns.

Highlights • Eco-labels and certifications for agricultural crops have yet to halt land use change. • Sparse and uneven market uptake only partially explain this outcome. • Loopholes in certification standards and enforcement mechanisms also play a role. • There is little evidence that eco-labels actually encourage land conversion for agriculture. Abstract In countries marked by the growing uptake of non-state market driven (NSMD) governance for agricultural commodities (i.e., eco-labels and certification systems), forested areas are steadily decreasing while crop lands are growing. This deforestation continues despite NSMD rules aimed at prohibiting the conversion of forested land to agriculture. In this paper, we ask why the growing presence of NSMD governance has coincided with ongoing deforestation. While the seeming inability of NSMD governance to halt broader patterns of land use change can be partially explained by a lack of market uptake, there are also a range of other variables that may contribute to this relationship. We probe the plausibility of five hypotheses through comparative case studies of sustainable soy certification in Brazil, palm oil in Indonesia, and cocoa in Côte d'Ivoire. Our findings indicate that NSMD governance has neither abetted, nor hindered, the conversion of forested land to agricultural production. We find strong evidence that a lack of broad market uptake limits the effectiveness of NSMD governance. However, we also find evidence that regulatory loopholes in NSMD systems may explain the inability of eco-labels and certification systems to halt broader patterns of land use change in countries with comparatively strong market uptake. Our results highlight critical problems related to expanding the reach and stringency of NSMD governance alongside the ongoing fragmentation of global environmental governance. The study contributes to scholarship on the impacts and effectiveness of transnational environmental governance. [ABSTRACT FROM AUTHOR]

This paper reports on recent improvements made to the FORMA ( Hammer et al., 2014a ) data product. The resulting system, FORMA250, is a 250-m alerting system updated daily. FORMA250 alerts are available through Global Forest Watch. These alerts can empower law enforcement officials, government agencies responsible for protecting forests, nongovernmental organizations, companies committed to sustainable forest management practices and supply chains, indigenous groups and forest-dependent communities. In addition, the alerts provide useful information for researchers who study temporal and spatial patterns of forest clearing. [ABSTRACT FROM AUTHOR]

This paper explores the role of aspirational capacity, one cognitive dimension of well-being, as a driver of deforestation among rural smallholders living in or near Mozambique’s portion of the Great Limpopo Transfrontier Park. Integrating analyses of remote sensing, socio-economic, and semi-structured interview data within a theoretical framework drawn from Amartya Sen’s capability approach, we examine land use decisions in the context of the available options people have to choose from as well as the factors influencing their ultimate choice. Land change detection analysis indicates that more forest conversion occurs within the park, but rates show considerable variation at the community level. We find no association between economic deprivation and deforestation rates. Limited aspirational capacity, manifested in expressions of helplessness and despair, a lack of perceived choices, and fewer agentive pursuits, is one dimension of poverty that does contribute to cropland expansion. Qualitative findings indicate that a more limited capacity to set, pursue, and achieve aspirational goals perpetuates agricultural land use traps and, consequentially, higher deforestation rates. Higher levels of aspirational capacity also contribute to negative conservation outcomes as people adopt the risky but profitable activity of illegal rhino hunting as a means to obtain other valued capabilities.

After forest governance reforms by the Brazilian government, Amazon deforestation rates dropped by almost 80% between 2004 and 2012. Since then, however, deforestation has slowly increased again, casting doubts on the long-term sustainability of past conservation policy achievements. Clearly, deforestation rates and the associated local drivers of land-use and land-cover change differ considerably across the region, and adapting public policies to dynamic local contexts and actor constellations remains a major challenge for decision-makers. This paper seeks to contribute to the related science-policy debate by applying frontier theory insights to map, quantify, and compare land-cover dynamics in the Brazilian Amazon between 2004 and 2015. Our theoretical framework performs well in explaining broad variations in scope, nature, and agents of land-use and land-cover change across different frontier regions. We observe two types of transformative processes at deforestation frontiers in the Amazonian context. First, recent frontier development is characterized by an intensification of cattle ranching, and an increasing share of agricultural activities in the production portfolio, which could be the result of better access to modern technologies and markets, combined with forest governance induced scarcity of land for expansion of historically dominant extensive pasture systems. Second, the share of medium and large-scale deforestation declines at first, but rebounds during the observation period in all frontier types after 2012. Further research is needed to better understand the role of the changing political environment in driving these medium and short-term transformations in land-use and land-cover change. Furthermore, policy-makers, international cooperation, and civil society must seek strong integration between value chain based governance measures and effective environmental law enforcement.

To study welfare effects of environmental change, data from household surveys may be linked to remote sensing data. Using spatial aggregation to link risks ecological fallacy, since surveys are usually representative for areas larger than the spatial scale of decision-making units. This paper uses survey-to-census imputation to estimate welfare indicators for small areas to study the effect of deforestation on subsequent inequality in the rural Solomon Islands. This country depends on logging for almost half of foreign exchange and one-sixth of government revenue, and most forested land remains under customary ownership. A sharp increase in log exports, to seven times the sustainable yield, and a major shift in export destinations as other countries withdrew from the tropical log trade represents an exogenous shock that helps to identify effects of deforestation on inequality rather than the reverse relationship. A standard deviation increase in the rate of forest loss over 2000 to 2012 raises the Gini index of inequality in 2013 by one-third of a standard deviation. Mean incomes and poverty rates are also higher, implying that deforestation makes some households richer while others become poorer. These precisely estimated effects would be obscured using more spatially aggregated data. [ABSTRACT FROM AUTHOR]

Recent years have witnessed an increasing interest in land-based investments for food, feed, fuel, and fibre, driven by the volatility in commodity prices, economic growth of emerging economies, policy drivers of biofuel demand, and investor strategies in the wake of the global economic crisis. This interest has led to a surge of foreign and local investments in developing countries, where land can be obtained at a lower cost, and it has led to fears of land grabbing. In this paper, we consider the problem of identifying the determinants of large-scale land acquisitions in Africa and employ a unilateral beta regression to explore the link between investments and a number of indicators related to both land supply and institutional features. The results on the resource-seeking nature of investments and the impact of the land governance indicators are mostly in line with the findings of other studies. On the contrary, the results on forest land being a driver for large-scale land acquisitions, especially from international investors in Africa, differ from previous findings and indicate commercial pressure on African forests that may lead to accelerating degradation and deforestation.

In agricultural commodity chains, companies with sizeable market shares are stepping up sustainability commitments through so-called ‘No Deforestation, No Peat, No Exploitation’ (NDPE) policies – yet the delivery is fraught with difficulties. Drawing on theories of hybrid public-private governance this paper explores how commodity chain actors themselves view the limitations of private regulation and the prospects for more effective supply-chain governance. As a case study, we present interview data from the palm oil commodity chains linking growers in Riau Province, Sumatra, Indonesia, with retailers in Europe. The findings demonstrate awareness of shortcomings in existing arrangements and the need for a stronger presence of both the Indonesian state and European governments. We discuss potential hybrid governance measures, highlighting the need for a pluralistic strategy that mobilizes the combined positive forces of civil society, business and government(s). We argue that, to advance such an agenda, hybrid governance must be conceptualized not simply as a matter of blending (and hence reifying) pre-existing and often highly problematic private and public institutions but as a question of how all such institutions may themselves be more thoroughly democratized in the process.

Cropland expansion is the primary driver of deforestation worldwide. Since land and rainfall are two crucial inputs for agricultural production, a lack of rainfall may have severe consequences on yields, which in turn may lead to a change in cultivated areas, with possible impacts on deforestation rates. Our paper explores this issue of drought induced deforestation that has been largely neglected in the literature. By focusing on Madagascar where agriculture is mostly rainfed, we demonstrate that between 2000 and 2013, clearing additional forests was a strategy that farmers employ to cope with the negative impacts of droughts. Using remote sensing data and fixed-effects panel regressions, we find that droughts increased deforestation by 7.6% compared to years of near normal weather. The impact was most severe in dry and semi-arid areas (up to +17%). When droughts occurred across consecutive years, deforestation declined, a result that is consistent with risk averse behavior of farmers. We show that these results are not driven by ecological mechanisms or by accidental fires. We then study the implication of these outcomes for conservation policy and demonstrate that protected areas were partly effective at buffering against upsurges in deforestation induced by droughts. Our results reinforce the notion that when deforestation is an agricultural problem, agricultural solutions must be combined with conservation policies to decrease deforestation.

Global efforts to protect biodiversity and slow deforestation rely heavily on the establishment of protected areas; land set aside that cannot be deforested or developed. This paper studies the macro-level relationship between rule of law and variation in avoided deforestation from protected areas. Using recent global satellite data from 2000 to 2012, I estimate the country-level avoided deforestation of protected areas established in this period via nearest-neighbor matching. I then use weighted least-squares regressions to explain country-level variation in estimated avoided deforestation as a function of a country’s governance characteristics as well as other country-level controls. Across 71 countries in this study period, protected areas were more effective in countries with higher levels of corruption control and protection of property rights, protected areas were more effective in more democratic countries, and there appears to be no relationship between political stability and avoided deforestation from protected areas.

The main aim of this study was to analyse topics of research, scientific production, collaboration among countries, and most cited papers on deforestation through a bibliometric and social network study of articles found in the Web of Science database. The most productive subject areas corresponded to Environmental Sciences, Ecology and Environmental Studies. The articles were published in 458 different journals. A total of 2051 research articles were obtained. The main challenges identified for deforestation include “land use change”, “conservation”, “climate change”, “rain forest” and “reducing emissions from deforestation and degradation”. Social and economic topics are understudied. An important level of international collaboration has been identified, including the triangle of the United States, Brazil and the European Union, as well as others. [ABSTRACT FROM AUTHOR]

Natural ecosystems provide a variety of services on which humans, and other organisms, depend for survival and well-being. These ecosystem services can be categorized as provisioning (production of food, fiber, water and other resources), cultural (non-material benefits, such as recreation, spiritual and other aesthetic values), supporting (primary production, pollination, decomposition and soil formation necessary for resource production) and regulating (biological control and other feedback mechanisms that maintain relatively consistent delivery of services). Ecosystems also have been viewed as producing “disservices”, such as pests, litter, biological hazards such as diseases, animal attacks, allergenic and poisonous organisms, and geophysical hazards such as floods and storms. Many of these disservices are induced by management practices such as deforestation and concentration of agricultural crops. Insects affect ecosystem services in a variety of ways, positively and negatively. The papers in this special issue are focused on managing insects and ecosystems, and their interactions, in ways that ensure sustainability of ecosystem services and that minimize induction of disservices.

Deforestation, ecosystem homogenization, and diversity loss are frequent problems in tropical livestock systems, which can foster substantial human-wildlife conflict when wild carnivores with declining prey bases turn to cattle depredation. The objective of this paper was to examine spatial and temporal variation in the presence, composition, and diversity of wild fauna, including predators and their prey base, in a well-established tropical livestock system. The study was conducted on a ~ 140,000 ha ranch in the Cerrado-Pantanal transition zone in Brazil, where large areas of improved pasture are bounded by blocks of intact montane forests and seasonally flooded lowland habitat. The study sampled wildlife with camera traps distributed across the land use gradient and rancher depredation observations were also obtained. Depredation accounted for the loss of 0.9% of the total herd in the sampling year, and the number of depredation events was greater closer to intact forest and distant from centralized ranch structures and mechanized operations. Mammal diversity was greatest adjacent to intact forest and supported a complete representation of the native trophic structure, including large predators such as jaguar ( Panthera onca ), puma ( Puma concolor ), and maned wolf ( Chrysocyon brachyurus ) and a diverse and abundant prey base. Sites progressively distant from intact forest and with more intensive conversion and development supported smaller subsets of the diversity and composition, and no apex predators. Livestock management practices to reduce the economic impact of depredation on calves requires faithful adherence, while opportunities exist for landscape management that will enhance diversity and facilitate movement of large mammals between intact forests.

During the past decades, overuse of land resources has increasingly contributed to environmental crises in China. To mitigate wide-spread land degradation, actions have been taken to maintain and restore ecologically valuable landscapes such as natural forests. However, the effects of the various vegetation protection policies that have been implemented in China since the late 1990′s still remain largely unknown. In this paper, we therefore focus on mapping land use and land cover change (LULCC) in Inner Mongolia, one of the key regions targeted by Chinese ecological restoration programs. We used 250-m MODIS time series and a random forest classification approach to generate annual probabilities for each land cover class between 2000 and 2014. We then applied a trajectory-based change detection approach based on a modified version of the Landsat-based detection of trends in disturbance and recovery (LandTrendr) algorithm to the probability time series and mapped land cover change trajectories. We found that our trajectory-based approach achieved high accuracies (overall accuracy 0.95 ± 0.02). It provides spatial-temporal land change maps that allow a land-use related interpretation of change patterns. Our change maps show that i) forest loss decreased rapidly after 2000 (from 15,717 ± 1770 ha in 2001 to 1313 ± 165 ha in 2014) and forest gain (190,645 ± 28,352 ha during 2001–2014) occurred in the ecological program zones, leading to a net forest increase in Inner Mongolia, and ii) cropland retirement (212,979 ± 54,939 ha during 2001–2014) mostly occurred at the early stage of ecological programs and mainly concentrated in drier environments and steep terrain. Overall, land cover mapping and trajectory-based land use analyses allowed a consistent characterization of LULCC over large areas, which is crucial for gaining a better understanding of environmental changes in the light of rapidly changing environmental policies and governance regimes in China.

The paper is focused on identifying and evaluation of the processes in the cadastral areas forming a large part of the Ostrava-Karviná coalfield in the Czech Republic. Seven basic processes, that reflect the trends in the landscape changes in the area of interest, are traced at three levels: across the entire study area, on the level of three smaller parts of the coalfield, and in more detail on the level of individual cadastral areas. The most frequently occurring processes (urbanization and abandonment in each period; deforestation, intensification of agriculture and afforestation in one period) are described in more details. The research was based on the evaluation of temporal-spatial land cover changes over a long period of time, from the 1830s to the beginning of the 21st century. The multitemporal analysis of land cover in the study area was based on stable cadastral maps, historical aerial photographs and orthophotos. [ABSTRACT FROM AUTHOR]

Covering 16% of global land surface, dry forests play a key role in the global carbon budget. The Southern Hemisphere still preserves a high proportion of its native dry forest cover, but deforestation rates have increased dramatically in the last decades. In this paper, we quantified for the first time the magnitude and temporal variability of carbon dioxide and water vapor fluxes and their environmental controls based on eddy covariance measurements in a dry forest site of central Argentina. Continuous measurements of CO 2 and water vapor exchanges spanning a 15-month period (Dec. 2009 – March 2011) showed that the studied dry forest was a net sink of carbon, with an overall integrated net ecosystem exchange (NEE) of −172 g C m −2 (−132.8 g C m −2 for year 2010). The cool dry season (May–Sept.) accounted for a quarter of the total annual NEE of year 2010 with low but steady CO 2 uptake rates (1 g C m −2 d −1 on average) that were more strongly associated with temperature than with soil moisture. By contrast, in the warm wet season (Oct.–April), almost three times greater CO 2 uptake rates (2.7 g C m −2 d −1 on average) resulted from a highly pulsed behavior in which CO 2 uptake showed sharp increases followed by rapid declines after rainfall events. Cumulative evapotranspiration (ET) during the whole study (595 mm) accounted for most of the rainfall inputs (674 mm), with daily water vapor fluxes during the wet season being four times greater compared to those observed during the dry season (1.7 mm d −1 vs. 0.45 mm d −1 ). Modeling of the partition of all evaporative water losses suggested that transpiration was the dominant vapor flux (67% of ET), followed by interception (20%) and soil evaporation (13%). The influence of air temperature on half-hourly CO 2 fluxes was notably different for the dry and wet seasons. In the 11–34 °C air temperature range, CO 2 uptake rates were higher in the warm wet rather than the cool dry season, yet this difference narrowed with temperatures >26 °C. The dry forest became a net CO 2 source at 40 °C. Our study provides new insights about the functioning of dry forests and the likely response of their CO 2 and water vapor exchange with the atmosphere under future climate and land use/cover changes.

The paper explores the dynamics of the forest cover change in the Iezer Mountains, part of Southern Carpathians, in the context of the forest ownership recovery and deforestation processes, combined with the effects of biotic and abiotic disturbances. The aim of the study is to map and evaluate the typology and the spatial extension of changes in the montane forest cover between 700 and 2462 m a.s.l., sampling all the representative Carpathian ecosystems, from the European beech zone up to the spruce-fir zone and the subalpine-alpine pastures. The methodology uses a change detection analysis of satellite imagery with Landsat ETM +/OLI and Sentinel-2 MSI data. The workflow started with a complete calibration of multispectral data from 2002, before the massive forest restitution to private owners, after the Law 247/2005 empowerment, and 2015, the intensification of deforestation process. For the data classification, a Maximum Likelihood supervised classification algorithm was utilized. The forest change map was developed after combining the classifications in a unitary formula using image difference. The principal outcome of the research identifies the type of forest cover change using a quantitative formula. This information can be integrated in the future decision-making strategies for forest stand management and sustainable development. [ABSTRACT FROM AUTHOR]

Climate change is one of the main threats of the modern society. This phenomenon is associated with the increase of the greenhouse gases (GHGs, mainly carbon dioxide – CO 2 ) emissions due to anthropogenic activities. Main causes are the burning of fossil fuels and land use change (deforestation). Climate change impacts are associated with risks to basic needs (health, food security and clean water) as well as risks to development (jobs, economic growth and the cost of living). Taking into account this phenomenon, several countries participated in the last United Nations Climate Change Conference in Paris (21st Conference of the Parties – COP21) and agreed to reduce their GHG emissions to limit the rise in global temperature to less than 2 °C. Main commitments and actions are focused in energy efficiency, renewable energy deployment and forest protection (increasing the CO 2 natural sinks). In this context, biofuels (from non-edible feedstocks) have the potential to replace fossil based fuels in the transport sector, being a carbon-neutral fuel. In particular, algae–based biofuel can play a dual role in this scenario: as photosynthetic organisms, algae can capture CO 2 from industrial emissions or from atmosphere and the resulting biomass can be used to produce a wide range of materials including biofuels. Therefore, this paper reviews the research advances of algae cultures with focus on the applications (CO 2 capture and bioenergy production) related to the targets of COP21 agreement. Main recent advances in algal research studies and projects are also presented. [ABSTRACT FROM AUTHOR]

The Amazon forest in the state of Maranhão ensures ecosystem services that directly and indirectly affect the life quality of its population and economy, via hydrologic and climatic regulation, among other benefits. Currently, only 25% of the original forest cover (24.7 thousand km 2 ) remains while illegal deforestation persists in a violent process that provokes visible social, economic and environmental harm. Simultaneously, Maranhão has seen record levels of burning, faces a water shortage and fights against the worst social and economic indicators in the country. Conversely, secondary vegetation covers 19.9 thousand km 2 (27% of deforested area) and is completely unprotected. Contrary to the international commitments assumed by Brazil to combat deforestation and restore forests, some of the political representatives of Maranhão have sought legal mechanisms to further diminish forest cover in public and private areas. To promote the conservation and restoration of Maranhão Amazon Forest, a multi-institutional network of researchers was established in 2015. This viewpoint paper aims to draw attention to this endangered region of the Brazilian Amazon and give science-oriented recommendations to policy makers in order to avoid more setbacks. We argue that Maranhão state must urgently establish a policy of Zero Deforestation, protect secondary forests and comply with the national forest restoration policy, thus ensuring long-term economic sustainability.

After 2010, refugees through the World peaked at the highest level since WW II. Most of this increment was realized between 2011 and 2015 years in the effect of the Syrian conflict and the Arabic spring, and refugee problem that is an important problem for the world emerged. This problem was analyzed in the macroeconomic dimension, in the health dimension by different studies. However, the energy and environmental economy dimensions of this problem has not been adequately analyzed. This paper explored the cointegration and Granger causality between the refugee population, traditional energy consumption(firewood, charcoal, and coal), economic growth, environmental pollution, and deforestation by the tests of Fourier Bootstrapping ARDL (FBARDL) and Granger causality with the Fourier method in the period 1985–2020 in Ethiopia, Sudan, and Uganda. Firstly, whether the series is stationary was investigated by using Fourier unit root tests. Then, the FBARDL test determined the evidence of cointegration among the variables. Finally, by applying Granger causality with the Fourier method, the evidence of unidirectional causality running from the refugee population and traditional energy consumption to deforestation and evidence of unidirectional causality running from the refugee population and traditional energy consumption to environmental pollution were determined. The analysis results draw attention to the impacts of the increasing refugee population on deforestation, and environmental pollution. Governments must develop their long-term environmental policies in the context of the effects of refguee population on sustainability. • The impacts of refugees on deforestation and sustainable environment were explored. • BARDL and Granger causality tests developed with the Fourier method were employed. • Unidirectional causality from the refugee to deforestation and CO 2 emissions was determined. • The results draw attention to the impacts of the increasing refugee population on sustainable environment.

Easter Island (Rapa Nui) is well known for the enigmas surrounding its unique megalithic statues, the moai, and the prehistoric (i.e., pre-European contact) Rapanui society that built them. These enigmas include, among others, the time of the island's settlement, the geographical origin of the first settlers, the technology associated with moai transportation and emplacement, the occurrence (or not) of an ecological and cultural collapse linked to the island's deforestation, and the potential influence of climatic shifts on ecological and cultural changes. Until recently, most explanations for prehistoric developments invoked anthropogenic causes, but the progressive development of paleoecological studies has incorporated a new perspective in which climate change and climate-human synergies have gained momentum. This paper reviews all paleoecological studies published to date and their contribution to a better understanding of Easter Island's prehistory, with a focus on four main aspects: (i) the discovery and settlement of the island, (ii) the eventual occurrence of climatic changes and its potential influence on landscape changes, (iii) spatiotemporal deforestation patterns, and (iv) the relationship between environmental, ecological and cultural shifts. Paleoecological research on Easter Island has proceeded through three main phases: a pioneer phase (1977–1992), a transitional phase (1993–2004) and a revival phase (2005–2020). During the pioneer and transitional phases, the paradigm of a self-induced prehistoric socioecological collapse known as the "ecocidal" hypothesis dominated the scene. However, new empirical evidence obtained during the revival phase highlighted the potential importance of climate change in prehistoric ecological and cultural developments. In addition, paleoecological records have provided novel insights into the initial discovery and occupation of Easter Island before Polynesian settlement. Paleoecological evidence has suggested or supported that (i) the island would have been discovered and sporadically/intermittently settled, possibly by Amerindian cultures, long before Polynesian colonization; (ii) climatic changes, especially centennial-scale droughts that occurred during the Medieval Climate Anomaly (MCA) and the Little Ice Age (LIA), would have influenced ecological trends and cultural developments; (iii) deforestation was not a synchronous island-wide process but occurred at different times and at different rates according to the catchment considered; and (iv) both climatic and anthropogenic drivers, along with feedbacks between them, would have been responsible for the prehistoric socioecological developments on Easter Island. A general conclusion is that Easter Island's prehistory is complex and cannot be resolved using simplistic and deterministic approaches from isolated disciplines. Rather, uncovering this prehistory requires an integrated framework with contributions from complementary research fields such as anthropology, archaeology, ethnography, history and paleoecology, among others. This paper explains the potential contributions of paleoecology, in the hope that researchers in other disciplines will be able to incorporate the available paleoecological knowledge into their own studies. From a paleoecological point of view, further coring is needed and the use of novel biomarkers is highly recommended. General recommendations are to increase the amount of raw data available in public repositories, to develop a multidisciplinary database for Easter Island and to adopt a problem-solving attitude focused on the main topics of interest. • A historical review of all published works on the paleoecology of Easter Island. • Three historical phases: the pioneering phase, the intermediate phase and the revival phase. • Emphasis on environmental changes and their potential influence on island's prehistory. • Challenges the paradigm of an irreversible population/cultural collapse before European contact. • Emphasizes the need for understanding the climate-ecology-culture system, its feedbacks and synergies.

• This paper probes the effects of deforestation on infant mortality in Indonesia. • Forest loss appears to reduce deaths of all infants, but results vary by gravidity. • Deforestation endangers infants born from first pregnancies, but not other infants. • Potential mechanisms like air pollution do not appear to be responsible. • The observed mortality pattern points to malaria's role in the observed deaths. Factors expected to change concurrently with forest loss—such as economic activity and air pollution—shape human health in different ways, making it difficult to ex ante predict the net impact of deforestation. This paper investigates the infant mortality effects of prenatal exposure to high biomass forest loss in Indonesia, a country with rich forest reserves increasingly being subjected to high levels of deforestation. Indonesia officially bans clearing in areas with high biomass natural forests (referred to henceforth as 'protected forests'), yet these forests face illegal logging. The analysis uses a fixed effects approach, essentially tracking how mortality responds to protected forest cover changes over time within districts. Results suggest that protected forest loss favors survival among all infants. However, there is variation in the protected forest loss-infant mortality relationship by pregnancy order or gravidity—while children born from women's higher order pregnancies are less likely to die when exposed to deforestation, children born from first pregnancies experience an increase in their risk of death. Potential mechanisms such as overall air pollution, economic activity and perinatal health care do not appear to explain the gravidity-specific effects of deforestation in protected areas. However, the observed pattern of results suggests that effects are being channeled through malaria—the disease, which is likely to increase with forest loss, tends to disproportionately infect women during their first pregnancy, thus causing greater harm to the children born from these pregnancies.

Over the recent years, metropolitan regions dealt with the growing problems of urban growth, land use/land cover changes, landscape fragmentation, deforestation and loss of natural vegetation. By its position in the Romanian Plain (southern Romania), Bucharest Metropolitan Area faced significant land transformations over the past centuries due its favourable natural, socio-political and economic conditions which shaped the prerequisites for intensive/extensive agriculture, urbanization and industrialization. The paper is aiming to provide an insight on the temporal and spatial evolution of forest ecosystems based on several statistical and spatial data issued from historical documents and cartographical materials covering the past over two hundred years: 1790–1912 (empirical approach); 1912–1990 and 1990–2014 (spatial and statistical analysis). The outcomes revealed significant forest withdrawal over the analysed intervals in relation to the main triggering driving factors (e.g. historical, political, economic). Moreover, the study is completed with valuable information on the biogeographical and ecosystem classification of forests in the study-area, as well as the conservation of forest ecosystems though natural protected areas.

Countries are grappling with how to monitor and evaluate the social impacts of reducing emissions from deforestation and forest degradation (REDD+) at national and sub-national scales as they develop REDD+ safeguard information systems (SIS). Given limited resources for social safeguard measuring, reporting and verification (MRV), and the fact that REDD+ is a performance based mechanism requiring monitoring over the medium to long-run, there is a need to develop SIS that are low cost, rigorous, and sustainable over time. Of critical importance are approaches that adequately operationalize social safeguards, provide opportunities for ongoing MRV, and are feasible in terms of within country human and financial capital. In this paper we provide an illustration of how publicly available social and spatial data can be used for the quantitative evaluation of the social impacts of early REDD+ activities using the example of Kalimantan, Indonesia. Our analysis suggests that in the very early stages REDD+ projects are doing a reasonably good job of protecting rights (Safeguard #3), and are having a negative impact on human welfare (Safeguard #5). Other social safeguards could not be effectively evaluated due to lack of appropriate indicators in publicly available population representative datasets. Our experience suggests that there are several opportunities and challenges for countries as they move forward with REDD+ SIS. We find that for Indonesia there is sufficient data to estimate impacts for some, but not all, aspects of REDD+ social safeguards. More recently collected data have greater potential for the linking of social and spatial datasets, and fairly straight forward matching methods can be applied to construct appropriate treatment and comparison groups. Challenges include limited ability to operationalize some safeguards using existing data sources, lack of geo-referencing in several publicly available datasets, incompatibility of data layers in terms of their spatial and temporal resolution and frequency, and the complexity of generating appropriate counterfactual scenarios. Despite the limitations of existing data sources, we recommend against designing entirely new systems for REDD+ SIS. Strengthening ongoing national and sub-national data collection efforts to include appropriate geo-referenced indicators for the full range of REDD+ social safeguard indicators, and integration of carbon and social MRV systems are important avenues to explore.

Cattle ranching in Brazil is a key driver of deforestation and greenhouse gas (GHG) emissions. The Brazilian government plans to reduce national GHG emissions by at least 36%, partly by reducing emissions in the livestock sector through strategies such as intensification, pasture improvement, and rotational grazing. In response, sustainability programs promoting these practices have begun operation. Though studies have previously investigated aspects of GHG emissions and sequestration in improved pastures, they have not linked improvements with programmatic interventions. We surveyed 40 cattle ranchers located in the Brazilian Amazon biome to investigate how GHG emissions differed between farms participating in livestock sustainability programs with intensified production and farms not participating in these programs. We found that participating farms produced 8.3 kg of CO 2 e/kg of carcass weight (CW) less than did non-participating farms, which represents 19% fewer emissions. Farms that had participated in a sustainability program for at least two years showed larger differences in emissions: 19.0 kg of CO 2 e/kg CW less for program farms compared with their counterparts, or 35.8% fewer emissions. Key drivers of the total CO 2 e/kg CW in all farms were enteric fermentation and manure management. This paper provides farm-level data supporting intensification as a possible strategy to reduce emissions per kilogram of beef produced, and suggests that future research efforts should focus on long-term impacts of intensification and expand metrics for success beyond GHG calculations.

This paper examines the historical drivers and barriers of three mitigation actions in Brazil: the expansion of no-till agriculture, reduction of deforestation, and increased displacement of gasoline with ethanol. The characteristics of these three economic changes align with evolutionary economic theories rather than neoclassical or environmental economics. Despite its cost-effectiveness, diffusion of no-till agriculture was contingent on social learning and flows of information within the agricultural regime. Brazil’s success in reducing deforestation rates was driven not by policies that changed the microeconomic calculation of farmers, but by command-and-control policies on deforestation enabled through landscape shifts. Brazil’s ethanol biofuels industry emerged due to both niche level innovation of ethanol production systems and pure-ethanol vehicles, and shifts at the landscape level that enabled mandated fuel blends, public procurement programmes, and public investment in R&D. These three economic changes correspond with the categories of reproduction, transformation and transition, respectively. [ABSTRACT FROM AUTHOR]

This paper evaluates the role of trade liberalization and agricultural intensification in mitigating climate change cause and effects on land use and emissions using a computable general equilibrium model. Our results indicate that cropland expansion triggered by climate-induced crop productivity changes results in deforestation and increases emissions in South Asia and globally. Global full trade liberalization on all goods is the optimum policy for South Asia despite significant global deforestation, but for the world, unilateral partial trade liberalization on all goods is a more appropriate policy while ensuring a considerable emissions reduction for South Asia. These results indicate that mitigation responses to climate change are location specific and no one trade policy is suitable at the regional and global levels. Lastly, agricultural intensification by improving productivity growth is the best strategy in land-based emissions mitigation, thereby avoiding the transformation of forest and pasture lands for agricultural cultivation both at regional and global levels.

Economic development and sustainable ecological and environmental development generally target different goals, and there are trade-offs and game-like behaviors between implementers and donors in reducing emissions from deforestation and degradation (REDD+) program. This paper analyzed the effects of evolutionary behaviors of REDD+ implementers and donors with respect to environmental service payments. Within a theoretical analysis framework, the evolutionary stable strategies of the implementers and donors under different contractual payments for ecosystem services (PES) scenarios are analyzed to explore contractual REDD+ payments through evolutionary game models. On this basis, anon-parametric local regression approach is used to analyze arrange of market-based contractual PES schemes in five REDD+ countries (Congo, Brazil, Ecuador, Nepal and Uganda). The results show the following: First, when the opportunity costs are less than the environmental benefits, some middle and high income developing countries are sufficiently incentivized to conserve forests, even without formal contractual PES scheme. This conservation occurs regardless of whether the industrialized countries will pay for the ecosystem services. Second, when the opportunity costs are greater than the environmental benefits, developing countries will generally not take the initiative to conserve forests when industrialized countries do not pay for the associated ecosystem services. Third, when there are enough contractual PES fines, developing countries will conserve forests, and the industrialized countries will pay for the ecosystem services. Finally, contractual PES fines are related to the costs of reducing emissions. Nepal has the largest marginal effect, and Uganda has the smallest. These results have implications for REDD+ program design and implementation: market-based contractual PES scheme should be given priority to regulate behavior of industrialized countries and developing countries in the PES scheme. Developing a targeted and differentiated contractual PES scheme requires an accounting of emission reduction costs in different countries. [ABSTRACT FROM AUTHOR]

Armed-conflicts often occur in tropical areas considered to be of high ‘conservation-value’, termed as such for their biodiversity or carbon-storage functions. Despite this important overlap, few studies have assessed how forest-biomass is affected by armed-conflicts. Thus, in this paper we develop a multinomial logit model to examine how outcomes of the interactions between carbon-storage, armed-conflict and deforestation rates are linked to social, institutional and economic factors. We use Colombia as a case study because of its protracted armed-conflict, high forest-cover, sustained deforestation rates and on-going peace processes. Our empirical results show that the impacts of armed-conflicts on forest-cover are connected to specific socio-economical processes, such as unequal land distribution and land-grabbing, which typically occurs as part of ‘agricultural colonization’. Findings address a research gap by providing statistically sound evidence for associations between armed-conflicts and land-related grievances, which has rarely been demonstrated empirically. Our results also suggest that forest commons are associated with reduced armed-conflict, and simultaneously provide contributions to carbon storage and to meeting basic needs. Moreover, our forest-conflict transition models provide useful visual means to capture and relay to policymakers-the causes of forest cover-changes in a conflict-affected country. Finally, our findings imply that in dedicating their efforts to resolving land-ownership disputes, the Colombian government might uphold their international climate change commitments via reducing deforestation and hence forest based carbon emissions, while pursuing their national security objective via undermining opportunities for guerrilla groups to operate.

Progressively adjusting climate policies will entail adjustment costs for society. This paper develops a conceptual model and numerical example that illustrate the risk associated with exposure to the high costs of complying with future emissions controls and how this risks trades off against that from potentially premature investment into abatement. We then highlight the potentially unique role of tropical forest protection in helping to manage these risks by providing a cost-effective “buffer” of near term emissions reductions at a globally significant scale. This buffer would provide insurance against the risk of suddenly tightening targets, as well as providing other critical environmental benefits. We further examine how a version of a private finance instrument in the form of long-dated ‘call’ options on verified reductions in emissions from deforestation and forest degradation (i.e. REDD +) can help to operationalize this risk-hedging buffer creation. Options on REDD + could aid both regulated businesses and tropical nations to manage their respective risks. REDD + options could deliver sufficient abatement to significantly hedge exposure of regulated entities to potential corrections in climate policy while channeling financial resources to defer deforestation even as climate policies continue to evolve.

This paper introduces and tests a geostatistical spatiotemporal hurdle approach for predicting the spatial distribution of future deforestation (one to three years ahead in time). The method accounts for neighborhood effects by modeling the auto-correlation of occurrence and intensity of deforestation, using a spatiotemporal geostatistical specification. Deforestation observations are modeled as a function of pertinent control variables, such as distance to roads and protected areas, and the model accounts for space–time autocorrelated residuals with non-stationary variance. Applied to the Brazilian Amazon, the model predicted the locations of new deforestation events with over 90% agreement. In addition, 100% of the deforestation intensity values were contained in the model’s confidence bounds. The features of the model and validation results qualify the model as a strong candidate for short-term deforestation modeling. [ABSTRACT FROM AUTHOR]

Summary Overpopulation and economic industrialization are two common explanations for deforestation. Political ecology, however, highlights that good governance and effective land management at the local level can offset the impact of population growth and development on environmental degradation. In this paper, we provide an innovative argument derived from political ecology to explain deforestation, but rather than pursing a “bottom up” approach to governance, we take a “top down” approach. We argue that the state can ease deforestation rates by weaning rural populations off of the consumption of biomass for their energy needs by expanding rural electrification access. Using a panel analysis of 158 countries for the years 1990, 2000, and 2010, we find that not only does rural electrification cause deforestation rates to decrease, but also that it is more robust in explaining deforestation than population growth or development. Our study provides two innovations to political ecology: it highlights that the state can help, rather than hinder, local populations with managing their local environments in a more sustainable way by providing them with (public goods-based) energy alternatives, and; it supplements political ecology’s qualitative focus on environmental degradation with a generalized quantitative analysis of state-based initiatives on deforestation. Our results suggest that current global initiatives addressing deforestation—specifically the Reduction of Emissions from Deforestation and Forest Degradation (REDD+) agenda of the United Nations’ Framework Convention on Climate Change—should not only assist local land managers, but also work with the state to ensure universal access to electricity.

The relationship between human welfare and deforestation in the Brazilian Amazonia has traditionally been thought to follow a boom-and-bust pattern. According to this pattern, forest clearing triggers rapid increases in human welfare levels (“the boom”) due to short-term economic gains; these levels then drop to below national or regional averages (“the bust”) after the forest stocks have declined, thus causing the local populations to become deprived of ecosystem services. However, recent studies have questioned the validity of this boom-and-bust pattern. In this paper, we use panel data and simultaneous autoregressive models to evaluate the effects of deforestation, urbanization, public investments, agriculture, and state policies on temporal changes in human welfare that occurred across multiple municipalities in the Brazilian Amazonia from 2005 to 2012, a period during which governments implemented a set of strategies aimed at controlling deforestation across the region. We found that: (a) signals of a boom-and-bust pattern are weak at the regional level, and therefore this pattern cannot be generalized across the entire region; (b) human welfare is increasing more rapidly in low-development municipalities than in high-development cities, and all municipalities are converging on at least one regional average rather than on a national average; (c) urbanization does not lead to positive changes in human welfare, which indicates that the infrastructure available in regional urban centers is limited; (d) public investments are negatively associated with human welfare growth, thus signifying that if public investments are not used to leverage the potential of other sectors of the local economy, human welfare will not improve; (e) agriculture is negatively associated with positive changes in human welfare at the local level, possibly due to the dominance of cattle-ranching as the predominant economic activity of this sector; and (f) state-level policies matter, and future analyses of regional trends in the realm of development and conservation across this region should take such policies into account. Finally, we suggest that although human welfare and deforestation retain a weak statistical relationship, we cannot contend that they have been fully decoupled. Forest loss across the region is still pervasive, and institutions are too weak to sustain the transition from a frontier development model to a conservation-centered model. [ABSTRACT FROM AUTHOR]

This viewpoint paper presents a reaction to the article by Brandt et al. (2016) . It highlights the complexities inherent to the attribution of deforestation impacts to policy interventions when using remote-sensing data. This critique argues that in the context of the Congo a suite of factors (i.e., population density in particular) other than those considered by Brandt et al. (e.g., type of forest, distance from roads and markets) play essential roles in determining the fates of forests. It also contends that care is needed when making decisions regarding which units will be included in the comparison group so that contextual factors and on-the-ground information are properly considered (e.g., when logging operations are inactive or when a concession is used for ‘conservation’ purposes). Finally, it proposes that a focus on an analysis of deforestation rates for a given level of timber production might be a metric that more accurately represents one aspect of the consequences of forest management, which should also consider the appraisal of trade-offs associated with a larger set of social, financial and ecological objectives.

Agricultural expansion in the Ecuadorian Amazon is carried out predominantly by small-scale farming systems, yet the impacts of smallholders on the ecosystem and social fabric are not fully understood. In this paper, we use the societal metabolism approach to operationalize the analytical concepts of complexity theory put forward by agro-ecology analysis. We define a typology of farming systems and assess the impact of different trends, such as population growth, the emergence of new farming practices and the implementation of policies aimed at increasing agricultural production, on (i) the livelihood of smallholders; (ii) the national economy; and (iii) deforestation and biodiversity loss. Our findings indicate that smallholders find themselves in a subsistence trap, in which intensification of agriculture does not lead to an improvement in income, exacerbates social inequalities, negatively affects the ecosystem and has negligible benefits for the national economy.

The low productivity of many tropical pasturelands is a major driver of deforestation and other negative environmental and socio-economic impacts. In Brazil, the second biggest meat producer in the world, 85% of cattle farms remain within extensive pasture systems, and cattle farming is by far the most important proximate driver of deforestation. It is possible to expand Brazilian agriculture with zero deforestation through improvements to rangeland productivity yet understanding of the challenges and motivations of the actual cattle farmers in the face of such a transition remains sparse. To better understand the importance of the underlying factors that lead to or inhibit improvements to land management, we used focus groups and semi-structured interviews (N = 250) with farmers from the state of Mato Grosso in the Brazilian Amazon. We found that the majority of the respondents (60%) claimed that the principal benefit of adopting good agricultural practices was increased productivity, followed by increased income (43%) and better farm administrative management (34%). The adoption of improved pasture management techniques was positively correlated with stocking rates (p < 0.005, r = 0.48). Farms that adopted improved pasture management, most often through rotational grazing had, on average, lower levels of forest cover (p < 0.05, r = 0.22). We found that scarcity of labour was the major issue affecting the adoption of improved techniques (36%), followed by financial constraints (18%). We also identified a shortfall in access to technical extension services to be a significant problem because 40% of the technical assistance is currently provided by vendors of fertilizers and other chemicals. To our knowledge, this is the first study to systematically assess the barriers to and the conditions surrounding the adoption of good agricultural practices in Brazilian pasturelands from the perspective of the farmers from the Amazon involved in the implementation of these practices. It is critical that decision-makers involved in the design of technical assistance schemes, education and credit programmes consider these factors if sustainable land management is to be realised at scale. In particular, the lack of skilled and available labour contrasts with the widespread assumption that new credit lines for sustainable agriculture will automatically result in better land management. A failure to consider factors discussed in this paper may contribute to the continued clearance of native vegetation and the environmental degradation of existing pasturelands, in addition to the persistence of widespread poverty among cattle-farmers. These results can assist the large scale implementation of sustainable land use policies in Brazil and elsewhere. [ABSTRACT FROM AUTHOR]

We performed a cradle-to-grave life cycle assessment (LCA) of a bio-based cosmetic cream containing Refined Palm Kernel Oil (RPKO). The objective was to investigate the importance of the RPKO production within the environmental impact of the cosmetic cream. We assumed a baseline scenario with best oil palm agricultural practices in Malaysia, and then tested different parameters, i.e. deforestation, peat soil drainage and improved effluent treatment, in order to check their influences. In the baseline scenario, transport of the cosmetic cream was the main contributing process (largest contribution for 11 out of 15 impact indicators). Contribution of the packaging of the cosmetic cream was also significant (largest for 2 out of 15). RPKO had a low impact contribution in the baseline scenario, albeit a much more critical one in the alternative scenarios. Deforestation and peat soil drainage (i.e. transformation and occupation) influenced two environmental indicators: Climate Change and Land Use. On Climate change indicator, deforestation caused an increase of about 9% of the cosmetic cream impacts and peat soil occupation an increase of 16%. On Land Use indicator, deforestation caused an increase of 3%, peat soil transformation and occupation caused increases of 938% and 41%, respectively. Methane capture from palm oil mill effluent treatment and conversion to electricity represented a low decrease of environmental impact of cosmetic cream (from −0.1% to −2.8%). This paper showed that the palm oil agricultural phase could have a non-negligible impact over the life-cycle of a cosmetic cream in case of deforestation and peat cultivation, despite its small contribution in both mass and economic terms.

For some time, Biochemists have been exploring the potential to produce biofuels as an alternative to fossil fuel energy. Biofuels can be derived from crops such as corn, soybean and sugarcane however these crops can contribute to water scarcity and deforestation. Furthermore, large areas of land are used that could otherwise be used for food production. Another possibility is to use microalgae, which does not have the disadvantages associated with crop-based biofuels. Depending on conditions, microalgae can produce bio compounds that are converted into biofuels. The built environment is responsible for around 40 to 50% of total greenhouse gas emissions through fossil fuel consumption. Not only is it necessary to design and to retrofit our built environment to be more energy efficient, but it is also necessary to consider alternative fuel sources. To date, this has mostly focused on solar, wind and geothermal sources, however one residential building in Hamburg Germany has adopted algae building technology in the form of façade panels which act as a source of energy for heating the apartments and for hot water. The climate in northern Germany is very different to Australia, and the question arises; what is the feasibility to adopt algae building technology in New South Wales? There are issues around the physical and technical aspects of the technology, the social and environmental aspects, the regulatory and planning aspects, as well as the economic considerations. This paper reports on a study with key stakeholders in New South Wales to explore barriers and drivers associated with the adoption of algae building technology. [ABSTRACT FROM AUTHOR]

On the western coast of Madagascar, the dry tropical forest of Kirindy may disappear in the next 50 years because of its rapid conversion into agricultural land by slash-and-burn cultivation. The slash-and-burn fields are cultivated during 3 years in average and are further abandoned because of soil depletion, weed invasion and finally lower crop yields. As a consequence, new forest areas are regularly cleared from the primary forest, causing deforestation. In addition, Madagascar is situated in a region with high cyclonic activity. Violent storms hit the western coast every 3–4 years, leading to intense rainfalls and floods. These events may enhance soil physical degradation and nutrient leaching, thereby accentuating the soil depletion by slash-and-burn agriculture and with it, the forest conversion rate. Focusing on the combined effects of historic land management and prevailing climatic conditions, this paper investigates: (1) the temporal evolution of soil fertility along with crop performance from cultivation up to field abandonment, and (2) the relative effects of land use (crop cultivation) and extreme climatic events (heavy rain, cyclonic storms) on soil and crop properties. We used a space-for-time substitution approach in slash-and-burn corn ( Zea mays L.) fields to describe dynamics of soil fertility and crop performance. We sampled soils and plants during two seasons: (a) a normal rainy season, in 2014, and (b) a cyclonic rainy season, in 2015. We found that under the cyclonic storm, soil becomes not only N and P deficient, but the K concentration also steeply drops. Overall, this leads to a dramatic reduction of corn performance. While a decrease in grain yield due to slash-and-burn agriculture reaches about 37.5% after three years of cultivation on the same field (from 4 to 2.5 t ha −1 ), it decreases up to 75% after a single cyclonic rainy season (from 4 to 1 t ha −1 ). On the sidelines of the study, a locust pest also damaged half of the corn fields in 2014, driving the corn yield down to zero on those particular fields. Given what precedes, the study points out the fragility of traditional agricultural techniques against natural hazards. Along with global warming, the frequency and intensification of natural disasters are expected to increase, impacting negatively and strongly the livelihoods of rural farmers. This raises the urgent need to increase farmer’s awareness to alternative and more sustainable agricultural practices. [ABSTRACT FROM AUTHOR]

In the 1990s, the Democratic People’s Republic of Korea (North Korea) suffered from severe food shortages and large-scale deforestation, which triggered a stage of rural conservation reform. Since 2004, with support from the Swiss Agency for Development and Cooperation (SDC), North Korea’s Ministry of Land and Environmental Protection (MoLEP) has implemented a Sloping Land Management Program (SLMP). The SLMP established sloping land user groups and granted these groups the right to use marginal land for agroforestry development. This devolution of land rights from state control onto local groups is a landmark in North Korea, and this decentralization initiative has now expanded to over eight counties to involve thousands of households. It has also led to the launch of a National Agroforestry Policy and Strategy. Drawing from both qualitative and quantitative data collected from 2008 to 2014, this paper documents the process and effects of the SLMP. It argues that the decentralization reform in land management has contributed to not only food security with increased food crop diversity and productivity, but also notably forest recovery through an expansion of tree plantations and agroforestry practices on degraded sloping lands. However, an insufficient power transfer in the form of a lack of timber rights granted to the local user groups has hampered the effectiveness of the SLMP. There are also institutional and geopolitical challenges that are limiting further scaling-up of land-use decentralization across the country. The policy implication calls for more international investment as well as national land-use policy reforms in order to promote and facilitate further decentralization of sloping land management and to secure greater use rights for sloping land user groups.

Land is a scarce resource affecting the implementation of many sectoral policies. In Indonesia, the expansion of palm oil plantations has led to non-sustainable land use practices in past years, particularly deforestation. More recently, the government has set ambitious targets for the adoption of biodiesel which will require expansion of oil palm plantations, thus putting further pressure on land. Meanwhile, the need to guarantee food supply, forest conservation and climate change mitigation also imply challenges when it comes to land allocation and use. This paper examines the role that land plays in the implementation of sectoral policies in Indonesia, exploring the availability of land to satisfy the multiple goals defined in national policies. We explore land competition resulting from allocations made in official policy documents starting with biofuel policy. The analysis of policy goals and coherence when it comes to land allocation is made in relation to agriculture, climate and forestry policies. We conclude that adjustments need to be made in the policies to avoid overlappings and misinterpretations when it comes to land allocation. The area made available for meeting each sectoral policy goal when taking into account cross sectoral interactions is: 14.2 Mha for agriculture, 43 Mha for climate mitigation measures, 9.2 Mha for forestry, and 20.9 Mha for biofuels. A more uniform land classification and development of a common reference database will increase transparency on land allocation and use, and help to monitor land use change, ultimately supporting the achievement of multiple national goals.

The aim in this paper was to evaluate the spatial distribution of protected areas defined by law and their importance as structural corridors. The study area was 7,559,783.69 ha located in Western Bahia (Northeast Brazil), restricted to the limits of the Urucuia Group (Upper Cretaceous), where there is strong agribusiness growth. Currently, a major dilemma in Brazilian public policy arises from the conflicting interests of environmental conservation and increased food production. Brazilian environmental protection policies include the implantation of Protected Areas (Full Protection Units and Sustainable Use Units) and the adoption of the National Forest Act (Permanent Preservation Areas and Legal Reserves). In this context, we delimited illegal land-use in Permanent Preservation Areas (PPAs) adopting the intersection between land-use/land-cover data from PRISM/ALOS image classification for the years 2007–2010 and PPA vectors. We performed the temporal analysis in PAs considering land-use/land-cover data from Landsat TM image classification for the years 1988, 1992, 1996, 2000, 2004, 2008 and 2011. Finally, we performed a Morphological Spatial Pattern Analysis (MSPA) to evaluate whether PPAs alone are sufficient as structural corridors. Hypothetical scenarios were simulated to increase the potential of PPAs as structural corridors. The calculation of MSPA attributes was conducted considering 3 edge widths: 15 m (1 pixel), 510 m (34 pixels), and 1005 m (67 pixels). Four scenarios were simulated, considering a gradual increase in preserved areas. The results show that illegal land use is contained within PPA and protected areas. The scenario simulations present alternatives to increase the connectivity of the fragments and ensure the maintenance of ecological and hydrological services. Rapid agricultural expansion without proper landscape planning can compromise the sustainability of ecosystem services and the recharge zone of the Urucuia aquifer. [ABSTRACT FROM AUTHOR]

Cattle farming is one of the most environmentally threatening industries worldwide. Its impact has been assessed as a main driver for soil degradation, deforestation, water bed contamination, and greenhouse gas emissions. Germany is one of the largest consumers and producers of livestock products in the world. This high volume demand for livestock forces farmers and consumers to import from overseas and increase national yields. Technologies worldwide are being developed with a focus on sustainability and cleaner production; however, this may not necessarily be easily adapted and implemented by German farmers. This paper uses the technology roadmap approach to propose a plan for implementing these technologies by identifying the barriers and actions to remove them. Aquaponics, grazing management, and capturing methane are current global trends used in the effort to reduce the impact of livestock. While aquaponics are at an early stage of development and implementation in Germany, grazing management techniques and methane processing on free range cattle are mostly still unknown and not implemented by farmers producing in the country.

Recent research shows that the combined contributions of deforestation, forest degradation and peat land emissions account for about 15% of greenhouse gas emissions. The REDD policy which preserves forests and values standing forests, enables substantial emission reductions. Since agricultural production and area expansion is a primary driver of tropical deforestation, REDD policies might limit the expansion possibilities of agricultural land use and therefore influence competitiveness of the agricultural sector, agricultural prices, trade patterns, agricultural production and therefore food security in the world. This paper studies the impact of REDD policies on the agri-food sector and food security with a global CGE model called MAGNET using a scenario approach. It focuses on the restrictions on agricultural land expansion within the REDD policy package. Simulation results show that REDD policies start to affect the agri-food sector in some lower developed countries if more than 15% of potentially available agricultural areas are protected from deforestation. A stringent REDD policy that protects 90% of land reserves that could potentially be used for agriculture production results in a global real agricultural price increase of almost 7.6%, and a worldwide agricultural production decrease of 1.7%. Regional differences are large, with real agricultural price changes ranging from 4% in North America to about 24% in Sub-Saharan Africa and South-East Asia. Food access rapidly deteriorates for low-income population in these regions in the case of high forest protection levels. Compensatory payments are necessary from a food security point of view if the level of forest protection increases. Our results indicate that from a food security perspective REDD policy should stop short of trying to protect more than 40% of global carbon if the compensation mechanism is not effectively implemented within REDD.

Over the last century, Paraguay has seen deforestation on a massive scale. At the same time, forest plantation efforts have been very limited. This paper examines why this is the case, and why until today investment in forest plantations in Paraguay is constrained despite visible wood shortages. Paraguay’s forest plantation sector is analyzed based on a typology of five plantation paradigms. This is followed by a critical diagnosis of the current plantation situation on the project level conducted through a SWOT-AHP analysis and supported by an expert survey. Thirty-six specific factors for establishing plantations are identified and evaluated for both small-scale and large-scale plantations. The analysis reveals strengths, weaknesses, opportunities and threats for both plantation types, and shows that small-scale plantations possess more highly valued strengths, while there are more significant threats for large-scale plantations. Critical conclusions and policy implications for expanding the scale of forest plantations in Paraguay are provided, focusing on forestry, institutional, political and intersectoral issues.

Corruption has often been blamed for causing deforestation, however, the evidence is mixed. The paper develops a framework to assess the impacts of corruption on forests and prioritize policy responses. Rather than relying just on a theoretical description of corruption, the framework is developed by analyzing how corruption manifests itself on the ground in the forest sector in Indonesia. The framework considers the potential impacts of corruption at different stages of forest management. We argue that to identify the specific impacts of corruption, it is necessary to understand intervening factors. It is shown that the impacts of different types of corruption on forests may be direct, indirect, ambiguous, or even negligible. Therefore, anti-corruption efforts should be more targeted to the specific types of corruption that are most likely to contribute to deforestation and forest degradation. [ABSTRACT FROM AUTHOR]
