Abstract: The conventional understanding of environmental governance implicitly assumes a priori presence of citizen rationality that underpins constitution of civil society vis-à-vis state. This assumption tends to overlook the economic and ecological consequences of social interactions through which people with diverse forms of rationality gradually produce distinction between state and society and shape environmental governance as an embedded process. This paper presents a case study of spontaneous settlers called posseiros in the south-east of the state of Pará in the Brazilian Amazon and examines ways that their social interactions lead to the so-called emancipation movements for municipal making on the agrarian frontier and open civic places in which environmental governance is negotiated. It pays particular attention to the role of religion, especially the Pentecostal Church of Assembly of God in relation to the traditional Catholic Church, in influencing the posseiros' ecological rationality and the articulation of emancipation movements and argues that the focus on religion sheds new light on the linkage between the environment, livelihoods and local governance. The paper concludes by discussing pragmatic implications of the case study for promoting sustainable rural development. [Copyright &y& Elsevier]

• SWAF-HR data is new water surface extent product at 1 km over the Amazon basin from 2010 to 2016 every 3 days. • SWAF-HR provided from the fusion of three datasets: water surface fraction at coarse spatial resolution from an L-band passive microwave sensor (Soil Moisture and Ocean Salinity – SMOS), Global Surface Water Occurrence from Landsat (GSWO) and the Digital Elevation Model (DEM) Multi-Error-Removed-Terrain (MERIT) based on the Shuttle Radar Topography Mission. • The flooded area of the Branco floodplain (Roraima) varies from 0.2 times 104 to 2.7 × 104 km2 whereas the extent of the Bolivian floodplain (Llanos de Moxos) inundation ranges between 0.8 × 104 and 8.1 × 104 km2 during 2010–2016. • The choice of the DEM in the downscaling process introduces 5% of error in the instantaneous water surface extent estimate but can reach up to 10% in the flood probability estimations over seven years. • (MERIT) based on the Shuttle Radar Topography Mission (SRTM). In this paper, we present a methodology to map inland water in tropical areas under dense vegetation at high spatial and temporal resolution using multi-source remote sensing data. A new inundation product (SWAF-HR) is presented. It is characterized by a high spatial resolution (30′, 1 km) and high temporal resolution (3 days). The SWAF-HR product is estimated over the Amazon basin for the 2010–2016 period. It is based on a downscaling procedure and the synergistic use of: (1) water surface fraction at coarse spatial resolution from an L-band passive microwave sensor (Soil Moisture and Ocean Salinity – SMOS), (2) Global Surface Water Occurrence from Landsat (GSWO) and (3) the Digital Elevation Model (DEM) Multi-Error-Removed-Improved-Terrain (MERIT) based on the Shuttle Radar Topography Mission (SRTM). Thanks to the high capability of L-band microwave emission to reveal surface water under all-weather conditions and beneath the vegetation, the inundated area extent estimated by the SWAF-HR product is always larger than GSWO estimates obtained by the optical sensor (Landsat). SWAF-HR data is compared to ESA CCI and IGBP land covers, two SAR images and flooded areas over the Purus basin computed by the MGB-IPH model simulation. The results show the coherence of spatial and temporal dynamics of the SWAF-HR data. We show that the flooded area of the Branco River floodplain in Roraima (Brazil) varies from 0.2 × 104 to 2.7 × 104 km2 whereas the extent of the Bolivian floodplain (Llanos de Moxos) inundation ranges between 0.8 × 104 and 8.1 × 104 km2 during 2010–2016. The flooded area in the Branco floodplain gradually decreased from 2010 to 2015 but in 2016, the flooded area has increased during the rainy season. During 2010–2016, the minimum of the inundated surface extent was reached during 2015–2016 reflecting to a drought event related to ENSO. The most important uncertainties of the DEM are located over tropical areas but this information is essential in the downscaling procedure. Therefore, we investigate the impact of the choice of the DEM for the downscaling procedure. It is found that the choice of the DEM introduces 5% of error in the instantaneous water surface extent estimate but can reach up to 10% in the flood probability estimations over seven years. This new SWAF-HR product will be helpful for the understanding of the water, carbon and biogeochemical cycles of the Amazon. [ABSTRACT FROM AUTHOR]

Summary: The present paper considers a sometimes contentious process of land reform presently occurring in Brazil. This process, referred to in the paper as Direct Action Land Reform (DALR), involves organizations such as the Landless Rural Workers Movement (Movimento dos Trabalhadores Rurais Sem Terra, or MST) and more spontaneous actions of individuals desiring a piece of land for their own. Results of a survey covering 751 households engaged in such land reform actions in the Brazilian Amazon are presented, in order to describe participants and land reform processes. Evidently, social movement organizations provide for a modest degree of wealth accumulation, a welfare improvement that must be set against potential environmental costs. The paper concludes by calling attention to the challenge DALR may ultimately pose to the Brazilian state. [Copyright &y& Elsevier]

Abstract: This paper seeks to understand how the Brazilian Amazon, which many thought unsuitable for agricultural development, has yielded to a dynamic cattle economy in only a few decades. It does so by embedding the Thunian model of location rents within the regime of capital accumulation that has driven the Brazilian economy since the mid-20th century. The paper addresses policies that have created location rents in Amazônia, the effect of these rents on land managers, and the spatial implications of their behavior on forests. Thus, the paper connects macro-processes and structures to agents on the ground, in providing a political ecological explanation relevant to land change science. The policy discussion focuses on reductions in transportation costs, improvements in animal health, and monetary and trade reforms. To illustrate the impact of policy, the paper presents data on the geography of Amazonian herd expansion, on the growth of Amazonian exports, and on the profitability of the region’s cattle economy. It follows the empirical presentation with more abstract consideration of the spatial relations between cattle ranching and soy farming, and implications for deforestation. The paper concludes on a speculative note by considering the likelihood of forest transition in the region, given the transformation of Amazônia into a global resource frontier.

Abstract: The immediate postpartum period is recognized as a special time in many societies and is commonly associated with food and work restrictions. The logic of food restrictions during a period of increased energy and protein needs has been challenged, but few data are available to test the impact of these practices on the diets of lactating women. In the eastern Amazon the immediate postpartum period is referred to as resguardo, lasts for 40–41 days and includes food taboos and work restrictions. Taking a biocultural perspective, this paper combines data on the beliefs and attitudes surrounding the practice of resguardo with quantitative data on the actual dietary intakes and activity patterns of a cohort of 23 lactating women followed from birth through 15 months postpartum. This paper addresses three topics: (1) shared ideals regarding resguardo; (2) adherence to food and work restrictions; and (3) the impact of these practices on women''s dietary intakes and energy expenditure. The results show that the majority of women adhered to food taboos and work restrictions. During resguardo energy expenditure in physical activity was lower, reducing women''s energy needs and allowing them to devote more time to infant care. However, energy intakes were also lower. The reduction in dietary intake was impacted more by work restrictions and the loss of women in subsistence tasks during resguardo than by adherence to food taboos. In addition to altering maternal energetic strategies, resguardo served an important social function by reinforcing bonds and, for young women, marking the transition to womanhood.

The management and governance of shared stocks have long been identified as a challenge to achieve long-term sustainability in fisheries. This is the situation of fisheries in the Amazon basin, a region shared by nine countries. This paper provides an overview of the social-ecological outcomes and management implications of sharing fish stocks among countries with different public policies, taking the valuable Amazonian ornamental silver arawana ( Osteoglossum bicirrhosum ) trade as a case study. Specifically, it (i) presents and discusses the policies of Colombia, Peru and Brazil for the silver arawana fishery, and how these are conducive for the successful management of this shared transboundary fishery; and (ii) analyzes the market for the ornamental silver arawana and how it affects the ability to sustainably manage the fishery. The interplay between the multiple environmental, economic and social dimensions involved in the ornamental silver arawana fishery affects the sustainability of this species even in Brazil, where this fishing is forbidden but still illegally caught by Colombians and Peruvians. Among the factors that make fisheries policies inefficient in this region are: (i) incongruent policies between the countries and institutions with low organizational capacity to accomplish the established policies; (ii) environmental heterogeneity of Amazonian aquatic systems, which requires local and adaptive measures; and (iii) complex socio-economic relationships in the live-fish trade business. Legally binding efforts to reduce problems derived from shared fish stocks are an urgent need and should be addressed by the multilateral organizations created for the Amazonian sustainable development.

Protected areas anchor the ecological infrastructure that societies need for long-term prosperity and provide benefits to local, national, and global stakeholders. However, these areas continue to go unfunded. In this paper, we have provided the first estimate of the return on investment for nine large protected areas that compose the core of the ecological infrastructure of the State of Amapá, which is located in a new forest frontier in Brazilian Amazonia. These nine protected areas will require US $147.2 million over five years in order to be established and then US $32.7 million in annual recurrent costs. If implemented, these nine protected areas have the potential to contribute at least US $362.4 million per year in benefits (timber, non-timber forest products, nature-based tourism, fisheries, and carbon) to the local economy. The return on investment (ROI) of these protected areas will be 1.6% during the first five years and 10% thereafter; however, ROI could reach 45.8% or more if option and non-use values are also included as benefits. Although the costs of establishing the protected area system in Amapá are higher (US $3.2–3.5 ha − 1 y − 1 ) than the costs reported in other tropical forest regions (US $0.2–0.4 ha − 1 y − 1 ), the investments required are within the reach of both state and national governments. Our study shows that if fully implemented, protected areas can become engines for socio-economic upliftment, making the conservation-centered development model a feasible option for most of the world's new forest frontiers.

Abstract: This paper seeks to analyze local perspectives in Peruvian Amazon forest communities toward REDD and contrast those perspectives with current global and national REDD narratives. REDD is a global market-based approach to provide financial incentives for local actors to halt deforestation or to improve carbon stocks. To date, the REDD framework has not demonstrated that it is equipped to incorporate the diverse perspectives, potential interactions and uncertainties facing forest communities. We interviewed forest community members in the Amazonian state of Loreto, Peru, using “future scenarios” methods to elicit potential alternative narratives, both with and outside REDD. Indigenous voices reveal ambiguous attitudes toward REDD with regard to livelihoods, benefit distribution and the long-term impacts for communities and forests. They reveal considerable uncertainty about the future and lack of trust in governance regimes. Long-term community priorities were in generating work, providing educational opportunities for their children, and improving the quality of their forest. Conflict—within the community, with local loggers and with the recently established regional conservation area—was a prevalent theme. A REDD design that recognizes communities as active participants in global and national climate management and pays attention to local narratives will more likely generate the multiple benefits of healthy forests, strong communities and, ultimately, global climate change mitigation.

• Air pollution in the Brazilian Amazon leads to increases in hospitalization rates. • Adverse effects are concentrated in respiratory conditions. • Effects are higher among children and the elderly. • Effects increase non-linearly with air pollution levels. • There are negative externalities related to deforestation in the Brazilian Amazon. In this paper we assess the effects of fire-related air pollution on population health in the Brazilian Amazon. Our empirical strategy is based on a municipality-by-month fixed effects model, coupled with an instrumental variables approach that explores wind direction and air pollution in surrounding areas in order to exogenously shift exposure to air pollution at the locality. We find that exposure to air pollution, measured by PM2.5 concentration levels, is robustly associated with an increase in hospital admissions for respiratory conditions. The effects are higher among children and the elderly, and increase non-linearly with pollution levels. Our benchmark estimates indicate that an increase of one standard deviation in PM2.5 is related to an increase of 1.5% of the monthly hospitalization rate for respiratory conditions. The latter estimate reaches 14% if monthly average PM2.5 crosses thresholds as high as 75 μ g/m3. We do not observe significant effects on hospitalization rates related to other health conditions nor on mortality rates. [ABSTRACT FROM AUTHOR]

Abstract: The Brazilian production of bentonite is approximately 300,000t/year, with more than 88% of this production concentrated in small deposits located in the Paraíba state (northeast Brazil), which consequently are becoming exhausted. The objective of this paper is to present a new occurrence of bentonite from the eastern Amazon in northern Brazil, here referred to as Balsas bentonite. A selected sample of the material was characterized by XRD, TG/DTA, ICP-OES, FTIR, SEM-EDS, N2 adsorption/desorption at 77K and CEC. The main constituent of the bulk sample is montmorillonite. Kaolinite is completely absent, in contrast to some bentonites found in the famous Paraíba state. The results obtained from the mineralogical and chemical characterization confirm that this material, in comparison to some reference bentonites from the Clay Mineral Society Source Clays, has promise as an engineering material, indicating its possible use in various research and industrial applications.

Abstract: The ecological consequences of climate change for large tropical forests such as the Amazon are likely to be profound. Amazonian forests strongly influence regional and global climates and therefore any changes in forest structure, such as deforestation or die-back, may create positive feedback on externally forced climate change. Monitoring, modelling and managing the impacts of anthropogenic climate change on forest dynamics is therefore an important objective of forest researchers, and one that requires long-term data on changes at the level of community, populations and phenotypes. In this paper we provide the most comprehensive study yet on the seasonal dynamics of various leaf traits: leaf area index (LAI), leaf mortality (LM), leaf biomass (LB), leaf growth rate (LG), and leaf residence time (TR) from 50 experimental plots in a forest site at Belterra, Pará State, Brazil. From this study we estimate annual mean leaf area index (LAI) to be 5.07m2 m−2 and annual mean leaf dry biomass to be 0.621kgm−2. The typical leaf grew at 0.049kgm−2 month−1 and remained on the tree for 12.7 months. We compare these results to other similar studies and critically discuss the factors driving leaf demographics in Amazonia. [Copyright &y& Elsevier]

Summary: This paper examines the interactions between state-led land reform, agrarian structures, and deforestation in the Brazilian Amazon. Land reform tends to promote land redistribution through regularization of smallholder land invasions of large-scale landholdings, and by redistribution of public lands to smallholders in existing colonization frontiers. The implications of state-led land reform on deforestation are heterogeneous. I argue that impacts of agrarian reform are strongly related to the pre-existing social and economic configuration of the frontiers where it takes place. While it leads to lower rates of deforestation in landscapes dominated by smallholders with diversified land use, its impact on forest conversion is higher in landscapes where extensive land use, mainly prompted by large-scale cattle ranching, tends to dominate. I provide an assessment for the whole Brazilian Amazon, and examine two research sites in the state of Pará, namely Uruará and Redenção. The study is based on informant interviews, secondary information, agricultural census data, and remote sensing data. [Copyright &y& Elsevier]

• Terra Legal had no overall impact on deforestation as of 2012. • Deforestation levels increased following Terra Legal in highly registered counties. • Spatial spillovers from Terra Legal were minimal in the short term. • Temporary crop cultivation decreased with greater registered area. • Investment loans increased in counties with more area registered by small and medium farms. This paper estimates the early impacts of Terra Legal , a large property rights reform, on deforestation and farming in the Brazilian Amazon. Twelve and a half million hectares, more than 2.5% of the Brazilian Amazon, have been registered under this program. The establishment of property rights may increase a farmer's incentive to invest in his land and expand his farm due to a lower risk of expropriation. On the other hand, the enforcement of conservation requirements may be easier when farmers have legal titles to their land. We use county level data from 2007 to 2012 on farm registrations, deforestation, crop choice and bovine management to test the impact of the Terra Legal land reform. While we find no overall impact of the program on deforestation during the period in our sample, we do show that there is substantial heterogeneity in impacts across counties. Counties with the largest area registered do have an increase in the level of area deforested, but they also have a decrease in the rate of deforestation. We investigate the extent to which changes in deforestation are related to the amount of registration that occurs among small, medium and large farms, and find limited support for less deforestation among counties with more area registered by small farms; more area registered by large farms is associated with a higher level of deforestation, but a decreased deforestation rate. Our results suggest that land tenure reform can create incentives to decelerate deforestation. Farm size has a strong impact on the farm management changes generated by improved property rights; coupling land tenure reforms with incentives to intensify production rather than expand could lead to reduced deforestation, particularly among small farms.
