Electronic assessments and corrections (EAC) of assignments, continuous assessments, and projects over type-printed versions stimulate students’ happiness owing to its economic and forest conservation components. Hence, the objective of this paper was to evaluate the crucial elements of economic and forest conservation by adopting absolute electronic assessments over typed-and-printed paper submissions (TPPS) for corrections in a Faculty of Agriculture at a Tertiary Institution in Rivers State, Nigeria, by collecting data from 188 500L using a Google Form questionnaire. The happiness index was determined using the Cantril Ladder scale as well as appropriate statistical tools. The data showed a low average students' happiness index (3.58); however, students in Forestry and Wildlife Management (4.79), Animal Science (4.26), and Fisheries (3.98) showed significantly higher happiness than students in other departments. The estimated economic cost of the printed paper submissions was ₦6,761,354.00 ($4,829.52) per session, compared to ₦370,970.8 ($264.97) for the electronic submissions. Study estimates indicated that participants used 326.55 reams of 80 gm A4-sized paper during their final year session, at an average cost of ₦41.41 ($0.029) per printing page. This is comparable to 741.28 kg of dried pulp, or 20.4 pulp trees. The substantial financial strain students endured on typed-and-printed paper submissions—more importantly, research project corrections have a profound negative impact on their happiness. By phasing out TPPS at the institutions of learning, students' happiness would be enhanced, while considerable economic and forest resources could be conserved.

Rewritable paper has recently become prevalent in both academic research and marketplace due to the potential environmental advantages, including forest conservation, pollution reduction, energy saving and resource sustainability. However, its real-life applications are limited by a lack of effective strategy to realize multicolour and water-jet printing on rewritable paper with long legible image-lasting times. Herein, we report an effective strategy to construct rewritable paper based on colour or luminescence switching induced by dynamic metal-ligand coordination. This type of rewritable paper can be conveniently utilized for multicolour water-jet printing by using aqueous solutions containing different metal salts as ink. In addition, the printed images on the water-jet rewritable paper can be retained for a long time (> 6 months), which shows great progress compared to previous work. We believe that this type of rewritable paper could be considered as a prototype for multicolour water-jet printing to meet the practical needs. [ABSTRACT FROM AUTHOR]

Campaigns by non-governmental organizations (NGOs) pressuring companies to adopt sustainability standards have caught academic interest in recent years. Critics of this approach toward increasing biodiversity protection and social justice argue that campaign successes are often short-lived while proponents emphasize the potential of NGO campaigns to achieve positive environmental and social change in the absence of governmental legislation. Focusing on the recent forest conservation policy of Asia Pulp and Paper (APP), a leading pulp and paper company operating in Southeast Asia, we analyze the challenges companies face in implementing sustainability commitments made as a result of NGO and market pressure. Drawing from research on policy implementation and corporate greening we identify key activities to help entrench APP's commitments in the company's operations. Furthermore, we suggest that a range of actions by different stakeholder groups can achieve broader effects of APP's commitments toward better environmental and social stewardship in the region's pulp and paper sector.

The agro-industrial grain industry generates a large amount of waste, which is often discarded, leading to environmental problems and the potential loss of valuable resources. However, in recent years an innovative approach has emerged that aims to use this waste to obtain cellulose, a compound with several industrial applications. The process of extracting cellulose from agroindustrial by-products of the food industry involves stages such as harvesting and milling, followed by a chemical and/or enzymatic treatment to obtain pure cellulose. Dependence on primary sources of pulp such as wood is reduced, thus contributing to the conservation of forests and natural ecosystems. In addition, the use of agro-industrial waste for pulp production reduces the amount of waste burned or poorly discarded, thus minimizing the environmental impacts associated with its disposal. Inadequate, in addition to the environmental benefits, the use of agro-industrial waste to obtain cellulose can also generate economic opportunities for many families who can use this medium to grow economically.

Land tenure security (LTS) is important for achieving many sustainable development goals but its influence on forest cover is mixed. The uncertain relationship between LTS and forests is driven, in part, by the moderating influence of other drivers of deforestation. In this paper we illustrate this complex relationship between LTS and forest cover for individual private landholders in the Colombian Amazon. We use household surveys and econometric analysis with matching techniques to examine whether formal land titles and perceptions of LTS influence forest cover. We explore how the effect of a land title on forest cover is moderated by perceptions of LTS, time to markets, and participation in a conservation program. We find that more secure land tenure, on average, has a statistically significant and negative influence on forest cover in our sample. The negative association between LTS and forest cover is stronger when landholders perceive they have secure tenure and are closer to markets. However, we find the negative relationship between land title and forest cover goes away when a landholder participates in a conservation program. While our cross-sectional data and quasi-experimental methods cannot lead to causal statements, our results are in line with many recent studies in the Amazon region, and our household-level data provides important insight regarding drivers of deforestation that moderate the relationship between land title and forest cover. Our results inform the design of future LTS interventions and conservation efforts. [ABSTRACT FROM AUTHOR]

The research described in this paper focuses on the development of an innovative unmanned aerial vehicle (UAV) tailored for a specific mission: detecting the acoustic signature emitted by chainsaws, identifying deforestation, and reporting its location for legality assessment. Various calculations were conducted to determine the optimal solution, resulting in the choice of a fixed-wing UAV. A comparative analysis between tri-rotor and quadcopter systems was performed, leading to the selection of the tri-rotor configuration. The primary objective of this study is to design an innovative hybrid UAV concept with key features including a fixed-wing design and integrated VTOL (vertical takeoff and landing) capability in the experimental model. The aircraft has been constructed using advanced materials such as fiber-reinforced polymer composites, manufactured using both conventional and advanced techniques like continuous fiber additive manufacturing and the use of a polymer matrix. Additionally, the aerodynamic configuration is optimized to achieve a cruise speed of approximately 50 km/h and a flight autonomy exceeding 3 h. The UAV has been equipped with payloads for mounting sensors to collect meteorological data, and crucially, the VTOL system has been optimized to vectorize thrust for improved performance during the transition from hover to cruise flight. This paper details the entire manufacturing and assembly process of the drone, covering both the structural framework and associated electrical installations. A dedicated sound detection system is incorporated into the drone to identify chainsaw noise, with the aim of preventing deforestation. [ABSTRACT FROM AUTHOR]

Detecting and localizing standing dead trees (SDTs) is crucial for effective forest management and conservation. Due to challenges posed by mountainous terrain and road conditions, conducting a swift and comprehensive survey of SDTs through traditional manual inventory methods is considerably difficult. In recent years, advancements in deep learning and remote sensing technology have facilitated real-time and efficient detection of dead trees. Nevertheless, challenges persist in identifying individual dead trees in airborne remote sensing images, attributed to factors such as small target size, mutual occlusion and complex backgrounds. These aspects collectively contribute to the increased difficulty of detecting dead trees at a single-tree scale. To address this issue, the paper introduces an improved You Only Look Once version 7 (YOLOv7) model that incorporates the Simple Parameter-Free Attention Module (SimAM), an unparameterized attention mechanism. This improvement aims to enhance the network's feature extraction capabilities and increase the model's sensitivity to small target dead trees. To validate the superiority of SimAM_YOLOv7, we compared it with four widely adopted attention mechanisms. Additionally, a method to enhance model robustness is presented, involving the replacement of the Complete Intersection over Union (CIoU) loss in the original YOLOv7 model with the Wise-IoU (WIoU) loss function. Following these, we evaluated detection accuracy using a self-developed dataset of SDTs in forests. The results indicate that the improved YOLOv7 model can effectively identify dead trees in airborne remote sensing images, achieving precision, recall and mAP@0.5 values of 94.31%, 93.13% and 98.03%, respectively. These values are 3.67%, 2.28% and 1.56% higher than those of the original YOLOv7 model. This improvement model provides a convenient solution for forest management. [ABSTRACT FROM AUTHOR]

- Abstract
Food systems of indigenous people across the world have developed within the confluence of forests, biodiversity, and seasonal crops. However, due to multiple socio-economic, cultural, ecological and political changes, this relationship has evolved over time. This has not only impacted traditional food systems; we hypothesize that it has also shifted communities’ social connectedness, stability and sense of purpose, thus profoundly impacting their sense of health and well-being or ‘flourishing’. Taking the case of the Solega tribe in South Indian forests as an example, this paper attempts to assess the status of the community’s flourishing in the context of the multitude of socio-ecological challenges they face. Household socio-economic survey and dietary recall were used to gather information on parameters that influence flourishing. The study reveals an interesting pattern of Solega’s sense of flourishing based on forest types and ecology, availability of diverse foods from the forest and crop choices. While traditional diets were determined by food produce collected from the forest and grown on their farms, dietary patterns today are determined by state sponsored food distribution programs and markets; and influenced by exposure to mainstream society. Data also show that flourishing scores are higher in forest types where traditional food continues to be grown or collected from forests as compared to those that have greater exposure to external exchanges. Apart from this, the data also indicate that the financial burden of having to purchase food, and the associated anxiety negatively influence perceptions of flourishing. While measures of flourishing can be complex, the study uses a parsimonious set of indicators to generate insights into the factors underlying Solega perceptions of flourishing, and their implications for food and nutrition policies and programs. We recommend that careful attention should be paid to the multiple roles that forests, and traditional farming practices play in shaping the perception of flourishing of indigenous communities, and more active support be integrated into food and nutrition policy and programs to ensure the sustainability of traditional food systems, including sources of food and dietary practices.

Mitigating and avoiding social unrest caused by ecological forest restoration is a key factor in the coordinated development of forests and society. Forests, which are intricately linked with society, serve as a vital source of timber, non-timber forest products, and ecosystem services. Ecological forest restoration projects must carefully consider the relationship between forests and society to promote their coordinated development. As a key implementation area for the Natural Forest Resource Protection Project, the state-owned forest regions in Northeast China have experienced a crisis regarding harvestable resources and social unrest caused by protection policies and are currently innovating in policies and practices to mitigate social unrest. This study focuses on the history of natural forest resource conservation projects in China's state-owned forest areas as a case study for empirical research, aiming to provide insights into ecological restoration models that foster harmony between forests and society. The empirical analyses reveal the following findings: (1) As a result of strict protection, natural forest resources on state-owned land have transitioned from providing timber to ecosystem services and non-timber products. (2) The strict logging ban policy has led to severe resource shortages; from 2000 to 2020, for every 10,000 cubic meter decrease in timber harvest, the per capita output in state-owned forest areas has dropped by more than CNY 500 (approximately USD 70). (3) Proactive ecological restoration can effectively alleviate social unrest; from 2000 to 2020, for every additional 10,000 hectares of forest tending, the average wage increased by more than CNY 900 (approximately USD 127). (4) Regional transformation can effectively generate a buffer effect to mitigate social unrest caused by strict forest protection policies and leverage the beneficial resources produced by ecological forest restoration to develop new drivers of economic growth. By systematically reviewing the comprehensive implementation of the NFPP, this paper's findings provide insights into ecological restoration strategies that promote the harmonious development of forests and society.

In the current context of climate change, this paper provides a brief overview of climate-vegetation interactions in the Mediterranean basin, where global warming and aridification trends are predicted to intensify. Rising temperatures coupled with extreme drought events have notable impacts on forest ecosystems, triggering dieback and mortality phenomena worldwide. The health status of forest vegetation may be assessed by either ground surveys or remote sensing. Several investigations of declining oak forests in the Apennine region have shown that the drought vulnerability of Mediterranean oaks is dependent on differences in access to deep soil water pools, which can be related to differences in rooting depth, tree size and growth rate. Forest dieback is widely reported in Italy, but the extent and overall distribution of this phenomenon have not yet been well defined. Thus, understanding the future dynamics of forest stands has several key objectives: inventorying declining forest stands to gain insight into the phenomenon and create a nationallevel database; locating these stands to allow monitoring of their evolution over time; and monitoring to allow planning of mitigation measures, as well as recovery and adaptation strategies. This background led to the implementation of SilvaCuore, the first web application designed in Italy to report forest health status. Silvacuore is a web application developed with the aim of improving the link between citizens and the scientific community by contributing to the development of a valuable scientific database. The direct involvement of citizens in forest preservation offers an interesting perspective because the innovative use of technology can tap into citizens' growing enthusiasm for environmental topics. Thus, SilvaCuore may be viewed from a dual perspective as a resource for the scientific community and as a unique opportunity for citizens to take an active role in research activities (Citizen Science project).

Forest discourses help identify forest-related issues. They aim to aid policy and decision-makers in understanding forest-related challenges and opportunities better so that they may initiate possible strategies and tactics to tackle them. Ideally, information requirements for the forest discourses would be translated into measurable variables, being the basis for collecting, analysing, and reporting data and information. Our study examined the connection between major international forest reporting processes and forest discourses. We analysed summaries and key findings for policy makers of five recent major forest reports. We compared their focus with forest discourses on climate change, forest conservation, deforestation, forest decline, illegal logging, industrial forestry/bioeconomy, traditional knowledge, woody biomass production, and innovative wood-based biofuels. The paper explores how the forest discourses are reflected in the surveyed documents and closely examines the specific focus areas in the summaries for policy makers. The results show that most forest discourses are generally well-represented, albeit with different foci. The discourse on illegal logging could not be identified in any investigated documents, even though it remains a significant concern for international forest policy. Keywords related to traditional knowledge and woody biomass production could not be found in two of the analysed findings. All analysed summaries and key findings mention issues related to the climate change discourse topic. However, they lack information on emissions from deforestation, carbon dioxide emissions and carbon budgets, which are high in political discussions. The paper highlights how discourse issues have gained in complexity both topic-wise and regarding the reporting obligations, as policy and decisionmakers require more timely and comprehensive information about the status' and trends of forests.

Forests are subject to a huge variety of often competing socio-economic demands and environmental change. This paper assesses the related conflicts that occur along what we label to be a "Global Forest Environmental Frontier". Assessing 11 contributions to a special issue on the same topic, it summarizes the main contents of these papers and concludes with an assessment of major trends. The contributions to the special issue take both a regional and topic-related approach, assessing forest environmental conflicts on all five forested continents and investigating issues such as forest biodiversity conservation, climate change adaptation and mitigation, environmental justice and equity, development, and forest management and conservation discourses. Taken together, they provide an overview on the multiple facets of the Global Forest Environmental Frontier, but also identify some shared patterns and trajectories, which are outlined at the end of this paper.

Forests are an essential part of the ecosystem and play an irreplaceable role in maintaining the balance of the ecosystem and protecting biodiversity. The monitoring of forest distribution plays an important role in the conservation and management of forests. This paper analyzes and compares the performance of imagery from GF-1 WFV, Landsat 8, and Sentinel-2 satellites with respect to forest/non-forest classification tasks using the random forest algorithm (RF). The results show that in the classification task of this paper, although the differences in classification accuracy among the three satellite datasets are not remarkable, the Sentinel-2 data have the highest accuracy, GF-1 WFV the second highest, and Landsat 8 the lowest. In addition, it was found that remotely sensed data of different processing levels show little influence on the classification accuracy with respect to the forest/non-forest classification task. However, the classification accuracy of the top of the atmosphere reflectance product was the most stable, and the vegetation index has a marginal effect on the distinction between forest and non-forest areas.

20. Evaluating the Determinants of Deforestation in Romania: Empirical Evidence from an Autoregressive Distributed Lag Model and the Bayer–Hanck Cointegration Approach.

Georgescu, Irina and Nica, Ionuț
- Abstract
This study focuses on deforestation, a key aspect of the current environmental decline linked to worldwide economic development and increasing populations. It examines how renewable energy consumption (RENC), GDP per capita, urbanization (URB) and foreign direct investments (FDI) have influenced the expansion of forest areas (FAG) in Romania from 1990 to 2022, utilizing an autoregressive distributed lag (ARDL) model and the Bayer–Hanck cointegration approach. The main results of the paper are the following: GDP has a positive and statistically significant long-term influence on FAG; URB and FDI have a long-term negative impact on FAG; and RENC is not a significant determinant of FAG. In the short term, a 1% increase in URB leads to an 809.88% decrease in FAG, while a 1% increase in the first and second lag of URB leads to a 323.06%, and 216.26% increase in FAG. This suggests that as more land is developed for urban use (like building homes, businesses, and infrastructure), the immediate consequence is a significant reduction in the area available for forests. This effect indicates a strong inverse relationship between urbanization and the availability of land for forests in the short term. Our results underscore the importance of sustainable development strategies, including green urban planning and robust forest conservation, to offset the adverse effects of increased FDI on Romania's environmental conservation, emphasizing the need for careful strategic planning and strong environmental policies to balance economic growth with forest protection.

One of the most problematic invasive species in Europe are knotweeds from genus Reynoutria (Fallopia) which have significant negative impact on the native communities as well on human activities. Therefore, they are a target of many control programmes. Due to their high regeneration potential, their management is problematic, and only chemical treatment is reported to be sufficiently effective. The aim of this paper was to describe and analyse the patterns of Reynoutria invasion under long-term chemical treatment with glyphosate-based herbicide in The Morávka river floodplain, Czech Republic. The data covers 17 years of management which started with the European project "Preservation of alluvial forest habitats in the Morávka river basin". We focus on (i) assessment of Reynoutria distribution during long-term management, (ii) analysis of the change of distribution according to the habitat, and (iii) discussion of the optimal management strategy based on the long-term data. Distribution data was obtained using GNSS field mapping. Before the start of the study in 2007, Reynoutria stands covered 29% of the study area (96.9 ha). As a result of systematic whole area chemical management, the extent decreased to 19.6% (65.3 ha) in 2009, and even reached 14.5% (48.2 ha) in 2013, three years after its end. Due to implementation of local chemical management in the following years, the area of Reynoutria was maintained at similar level, with minimum value 41.8 ha in 2018 and a slight increase in recent mapping in 2023. Beside the extent, the structure and coverage of invaded sites was analysed. There was a clear trend of fragmentation of larger polycormons with high coverage into many smaller and less dense ones as a result of chemical spraying. The average size of Reynoutria stand decreased from 0.61 ha in 2007 to half in 2013 (0.32 ha) to 0.15 ha in 2023. Testing of the effects of time, habitat, and biotope did not reveal significant differences of changes of extent and abundance over different environments (forest, open, bare ground), which indicates that there are no differences in reaction to management in the studied habitat and vegetation types. Our study provides a robust and unique overview of the invasion, reinvasion, and suppression dynamics for an important invasive species. If herbicide management is used, chemical treatment must be quite long-term as even three years of intensive glyphosate foliar spray application was not sufficient for the complete eradication of Reynoutria. Therefore, we propose the following procedure for effective chemical management of Reynoutria: 1) In largely infested sites, the first step is to reduce the distribution of Reynoutria stands to isolated polycormons. This phase can last 3–5 years. 2) After reaching the state of sparse distribution of Reynoutria, we recommend herbicide application only in periods of every 3–5 years depending on the local context and rate of regrowth. 3) At sites exposed to soil disturbances, where the soil is contaminated by fragments of Reynoutria rhizomes, there is a need to apply herbicide immediately to target newly resprouting individuals.

As it is known that "reconnecting to nature" is essential for sustainability, there are few studies on why reconnecting humans to nature is essential and how it can be accomplished. This study is aimed at finding innovative, yet sustainable ways to reconnect people with nature. The objective of the paper is to enhance the biodiversity knowledge of local residents through conservation of non-timber forest products (NTFPs). In the study, urban respondents' knowledge about biodiversity with particular reference to non-timber forest products (NTFPs) was analysed for the first time. To achieve the objective of this study, participatory appraisal, one-on-one interviews, dual moderator focus groups, ethnographic field research, and semi-structured questionnaire were used. Plant name boards with local names and their NTFP values for the selected species were also installed. Results suggest that NTFP-producing species played a vital role in making people interested in biodiversity. It can be considered as one of the innovative ways to improve surrounding biodiversity, for further enhancing biodiversity knowledge, based on archival study and local community's knowledge about NTFP producing species, NTFPs plantation also done across the study area like parks, roadside, open space. This paper also explored how this study could contribute to the formulation of policies in terms of creating various urban green covers in Indian cities, following the strategies of joint forest management, social forestry, and agroforestry.

Litter raking was a traditional forest use representing an interface between forestry and agriculture. In forest history, it has usually been presented as the harmful removal by peasants of biomass, which was gradually eliminated by foresters, leading to better forest preservation. Based on the example of an exceptionally well-documented case of illegal litter raking in Moravia in 1845, in this paper I argue that juxtaposing foresters and peasants in connection with litter raking masks a much more complicated reality. Neither foresters nor peasants can be interpreted as homogeneous groups because there were significant differences in the opinions and agendas of various representatives within these groups. In addition, opinions were not static on either side but could change in a discursive pattern. In a wider context, the environmental historical analysis of the Horka litter raking incident facilitates the understanding of larger societal processes that influenced past woodland management in Central Europe, and therefore current ecosystems too.

This paper presents a comprehensive forest mapping system using a customized drone payload equipped with Light Detection and Ranging (LiDAR), cameras, a Global Navigation Satellite System (GNSS), and Inertial Measurement Unit (IMU) sensors. The goal is to develop an efficient solution for collecting accurate forest data in dynamic environments and to highlight potential wildfire regions of interest to support precise forest management and conservation on the ground. Our paper provides a detailed description of the hardware and software components of the system, covering sensor synchronization, data acquisition, and processing. The overall system implements simultaneous localization and mapping (SLAM) techniques, particularly Fast LiDAR Inertial Odometry with Scan Context (FASTLIO-SC), and LiDAR Inertial Odometry Smoothing and Mapping (LIOSAM), for accurate odometry estimation and map generation. We also integrate a fuel mapping representation based on one of the models, used by the United States Secretary of Agriculture (USDA) to classify fire behavior, into the system using semantic segmentation, LiDAR camera registration, and odometry as inputs. Real-time representation of fuel properties is achieved through a lightweight map data structure at 4 Hz. The research results demonstrate the effectiveness and reliability of the proposed system and show that it can provide accurate forest data collection, accurate pose estimation, and comprehensive fuel mapping with precision values for the main segmented classes above 85%. Qualitative evaluations suggest the system's capabilities and highlight its potential to improve forest management and conservation efforts. In summary, this study presents a versatile forest mapping system that provides accurate forest data for effective management. [ABSTRACT FROM AUTHOR]

Recent observations suggest that repeated fires could drive Mediterranean forests to shrublands, hosting flammable vegetation that regrows quickly after fire. This feedback supposedly favours shrubland persistence and may be strengthened in the future by predicted increased aridity. An assessment was made of how fires and aridity in combination modulated the dynamics of Mediterranean ecosystems and whether the feedback could be strong enough to maintain shrubland as an alternative stable state to forest. A model was developed for vegetation dynamics, including stochastic fires and different plant fire‐responses. Parameters were calibrated using observational data from a period up to 100 yr ago, from 77 sites with and without fires in Southeast Spain and Southern France. The forest state was resilient to the separate impact of fires and increased aridity. However, water stress could convert forests into open shrublands by hampering post‐fire recovery, with a possible tipping point at intermediate aridity. Projected increases in aridity may reduce the resilience of Mediterranean forests against fires and drive post‐fire ecosystem dynamics toward open shrubland. The main effect of increased aridity is the limitation of post‐fire recovery. Including plant fire‐responses is thus fundamental when modelling the fate of Mediterranean‐type vegetation under climate‐change scenarios.

To gain a thorough grasp of the soil quality conditions in the preservation forests along the Tarim Desert Highway, a detailed assessment of the research area's soil quality is necessary, along with the identification of any potential obstacles. This evaluation should identify any potential obstacles and provide a theoretical basis for the sustainable utilization and precise management of protection forest soils. This paper examines the protection forest along the Tarim Desert Highway as the study area. To characterize the features of the soil quality, thirteen indicators of the chemical, physical, and biological composition of the soil were examined. The principal component analysis method was used to construct the minimum dataset (MDS) for soil quality evaluation. The diagnostic model for obstacle factors was combined with the MDS to explore the soil quality characteristics and obstacle factors in the study region. The findings indicated that (1) the constructed indexes of the MDS of protection forest soil in the study area included soil ammonium nitrogen (NH
4 + -N); quick-acting phosphorus (AvP); organic carbon (SOC); alkaline phosphatase (AP); and total salt (SS); (2) soil quality based on the MDS and the total dataset (TDS) showed a significant positive correlation (R2 = 0.748; p < 0.05), and the research region's soil quality were all in the medium and below level (100% of SQI ≤ 0.6), showing the status quo of high soil quality in the two ends of the shelterbelt forest and the tower center area, while the other areas were relatively low; (3) according to the findings of the soil barrier analysis, the two main obstacles influencing the soil quality of the shelterbelt forest at this time are NH4 + -N and SOC, and that the soil quality of the shelterbelt forest could be improved by artificially increasing the inputs of nutrients and precise conservation measures, promoting the overall function of artificial protective forests on desert highways. In addition to providing a solid scientific foundation for the sustainable use and maintenance of shelterbelt forests along the Tarim Desert Highway, this study is also an invaluable resource for researching the soil quality of artificial shelterbelt forests in arid regions.

1 Forested landscapes as multidisciplinary spaces contributing to all 17 Sustainable Development Goals (modified from Mansourian [12]) However, forest landscapes are under pressure with the loss of forest areas by conversion to other land uses and degradation of existing forests, and reduced biodiversity. The paper of Jandl et al. ([11]) considers the strategy of non-management and of the reliance solely on natural forest dynamics as an optimal approach for adapting forests to climate change. Forests and forest landscapes, characterised by dominant forest areas with other embedded land uses, fulfil multiple essential ecosystem services (ES). With this, forests and forest landscapes may lose their characteristic structural and ecological features, and societies worldwide face diminishing levels of ecosystem services provided by forest landscapes.

This article focuses on the (dis)continuity of sacred forests' management in the Pare Mountains, Tanzania, and questions the reasons behind the big generational divide when it comes to forest conservation. Studies show that sacred forests in North Pare are better preserved than national forest reserves and scholars suggest that the reasons for such high biodiversity are the communities' local traditions and conservation methods. Because local caretakers enable well-organized conservation with low economic expenditure, sacred forests' management has been thus recently considered a new favoured type of conservation model. However, the results of my ethnographic !eldwork show that at stake in this context, is much more the basic question of how this traditional knowledge can be gained in the first place. While it is commonly accepted that the main causes of forest destruction are farming, the cutting of building poles, etc. this paper highlights that the biggest concern regarding sacred forests' conservation for people in North Pare is the young generations' distance from sacred forests. I suggest therefore that changing worldviews have to be considered in the debate of sacred forest conservation and that knowledge transfer to the next generation of custodians (and mechanisms to ensure this happens) can complement recent conservation efforts, which typically neglect such generational issues.

How do firms address complex collective action problems effectively? Institutional and stakeholder research suggests that firms may avoid the tragedy of the commons by aligning the interests of critical proximate stakeholders in ways that governments cannot accomplish. This phenomenological paper investigates this possibility by analyzing Amazon rainforest preservation by Natura, a Brazilian cosmetics company. The results indicate that Natura internalized environmental externalities by linking ecologically conscious consumers with rural Amazonian communities. A differences-in-differences analysis compares forest preservation and fire activity in the municipalities that Natura entered with those in which it did not enter. Natura's impact is identified through an instrumental variable analysis using missing satellite images, which Natura relied upon to decide which municipalities to enter. Quantitative results tie Natura's entry into municipalities with forest preservation. Analysis of three mechanisms associates Natura's involvement with stakeholder decisions to cultivate diverse forest-generated crops instead of clearing the land for conventional agriculture. This study contributes to the management literature by suggesting how firms can address important global challenges, such as rainforest preservation, by investing in stakeholder capability development and by creating institutional arrangements in line with those envisioned elsewhere.

The Amazon Forest, the largest contiguous tropical forest in the world, stores a significant fraction of the carbon on land. Changes in climate and land use affect total carbon stocks, making it critical to continuously update and revise the best estimates for the region, particularly considering changes in forest dynamics. Forest inventory data cover only a tiny fraction of the Amazon region, and the coverage is not sufficient to ensure reliable data interpolation and validation. This paper presents a new forest above-ground biomass map for the Brazilian Amazon and the associated uncertainty both with a resolution of 250 meters and baseline for the satellite dataset the year of 2016 (i.e., the year of the satellite observation). A significant increase in data availability from forest inventories and remote sensing has enabled progress towards high-resolution biomass estimates. This work uses the largest airborne LiDAR database ever collected in the Amazon, mapping 360,000 km
2 through transects distributed in all vegetation categories in the region. The map uses airborne laser scanning (ALS) data calibrated by field forest inventories that are extrapolated to the region using a machine learning approach with inputs from Synthetic Aperture Radar (PALSAR), vegetation indices obtained from the Moderate-Resolution Imaging Spectroradiometer (MODIS) satellite, and precipitation information from the Tropical Rainfall Measuring Mission (TRMM). A total of 174 field inventories geolocated using a Differential Global Positioning System (DGPS) were used to validate the biomass estimations. The experimental design allowed for a comprehensive representation of several vegetation types, producing an above-ground biomass map varying from a maximum value of 518 Mg ha−1 , a mean of 174 Mg ha−1 , and a standard deviation of 102 Mg ha−1 . This unique dataset enabled a better representation of the regional distribution of the forest biomass and structure, providing further studies and critical information for decision-making concerning forest conservation, planning, carbon emissions estimate, and mechanisms for supporting carbon emissions reductions.

The importance of using evidence in decision-making is frequently highlighted in policy reports and scientific papers. However, subjective judgments of the reliability of environmental evidence vary widely, and large-scale systematic searches for evidence are only common for climate-related topics. In the medical field, evidence-based guidelines are routinely used to guide treatments. In the management of multiple-use landscapes similar guidelines could substantially narrow the science-practice gap but are largely absent. The challenges potential guidelines face are therefore unknown. For the case of forest conservation, we conducted 14 semistructured interviews with mainly forest practitioners and presented them an example medical guideline together with evidence-based statements on forest conservation (hereinafter: statement paper). We identified 28 concerns related to potential evidence-based guidelines in forest conservation. The interviews yielded approximately three major findings. First, recommendations on forest conservation are better accepted if they include clear instructions and are formulated for a specific context. Fragmentary conservation evidence complicates the formulation of specific recommendations. Second, the level of evidence framework, which indicates the strength of the available evidence, is perceived as too complex. Third, neglecting forest multifunctionality in a potential guideline hampers its application but, if addressed, potentially weakens its ecological relevance. We show that major concerns about potential evidence-based conservation guidelines are similar to the challenges experienced by medical guidelines. We also identify concerns unique to forestry.

Carbogel, a "polyacrylic acid", has been applied for cleaning different materials in the field of archaeological conservation, but it was rarely applied on wooden artifacts, and its effect on wood has not been assessed. Therefore the aim of this paper is to study the effects of carbogel poultices on one type of wood, namely pine wood, a softwood commonly used in many countries around the world throughout history. Three different Carbogel poultices were prepared by mixing in: distilled water, water and ethyl alcohol and water and acetone. Wood samples were covered with the different carbogel mixtures for 5, 15 and 30 minutes. To assess the long term effect of Carbogel on the treated wood, samples were exposed to accelerated heat ageing and humidity. Infrared spectroscopy analyses of treated and aged wood were conducted to study the effect of the poultices on wood components. Color change measurements and visual examination using a digital microscope were recorded. The results obtained indicated that carbogel can be safely applied in cleaning wooden artifacts made of softwoods, because its effect on wood components is minute and color change is negligible.

The Qinghai–Tibet Plateau is a unique global natural geographical unit with a high altitude and fragile ecology, where land cover change has been affecting its regional ecological security and sustainable development. The plateau covers nine countries with different variations in climate change and human activities, which cause significant spatial variations in its land cover change. This paper uses land cover data to reveal the spatiotemporal characteristics and multi-country differences in land cover change on the Qinghai–Tibet Plateau from 1992 to 2020 by applying spatiotemporal characteristic analysis and mapping methods. The results show that grassland (65.70%), bare land (15.56%), and woodland (10.25%) are the main types of land cover on the plateau, accounting for 91.51% of the total area. The interconversion of bare land and grassland was dominant in 1992–2020, with an area share of 67.83%. The turning point year of grassland change occurred in 2015. The grassland area increased by 6312 km
2 in 1992–2015, while it decreased by 14,646 km2 in the plateau in 2015–2020. The areas of woodland, cropland, and water increased by 2.77%, 5.85%, and 7.57%, respectively, and the area of built-up land increased from 299.17 km2 to 1206.29 km2 . Overall, a warming and wetting trend of the climate in the Qinghai–Tibet Plateau has driven the expansion of natural vegetation and water in the central plateau within China, with its natural vegetation area increasing by 0.11%. However, the development of regional warming and drying caused local grassland degradation, where Kyrgyzstan and India within the Qinghai–Tibet Plateau experienced the most prominent vegetation degradation. Human activities are relatively frequent in the Qinghai–Tibet Plateau within China and India, causing higher growth rates of built-up land and cropland than in other countries. The establishment of reserves and effective forest management policies have led to significant increases in woodland areas in China and Nepal within the plateau, while weak forest management and limited investment in forest conservation have led to high rates of deforestation in India and Myanmar. Accelerated temperature rises and regional differences in precipitation are the main drivers of large-scale land cover change on the plateau and differences in human activities and land use policies are responsible for the dramatic and diverse localized land cover change.

The Venezuelan economic crisis, combined with the creation of the Orinoco Mining Arc (OMA), has pushed thousands of people to work in wildcat mines in the Venezuelan Guayana. Even though attempts have been made to control illegal mining in the past, the absence of planning and lack of concrete economic alternatives have made these efforts unsuccessful. Spatial planning could play an important role in developing a rural regional strategy aimed at making other livelihood options available. This is a challenging endeavour, however, because the Venezuelan Guayana is the largest and least populated region of the country, with most of its surface covered by fragile forests rich in ecological and cultural diversity. Moreover, data to inform decision-making are unavailable or severely limited. This paper presents an approach that attempts to overcome those obstacles and seeks to identify which are the peripheral remote areas where resource extraction and its negative externalities are most present, conflicting with the preservation of the forest, its biodiversity and the livelihoods of Indigenous populations. The conclusions presented here might assist spatial planners and policymakers who seek to explore territorial approaches for rural development and inform decision-making in peripheral regions where data are scarce.

HUNTING ,RURAL development ,FOREST conservation ,SOCIOECONOMIC factors ,LAND use - Abstract
Hunting is a unique form of activity in rural areas with a high proportion of forest areas, which involves nature conservation and meets social needs for recreation and the preservation of traditions while being an important part of economic activity. The presented study results, based on a literature review and questionnaire surveys conducted among hunters associated in hunting clubs in the north-eastern part of Poland, provide the basis for a discussion on the socio-economic significance of hunting, both in the country and throughout the European continent. Based on the results presented in the paper, it can be concluded that the number and density of hunters differ in individual countries. Moreover, hunting is practised in Europe by almost 7 million people, of which 127,000 are in Poland, and is a typical male activity. Most hunters in Poland and other European countries are professionally active inhabitants of rural areas, aged approximately 50 years, with several years of shooting experience and an income exceeding average values. Hunting is an important part of socio-economic activities, particularly in rural areas. It is estimated that in the EU alone, hunting can be worth approximately EUR 16 billion, and creates 100-120 thousand jobs. The most recent results of studies conducted in certain EU countries and the wide range of services provided by the hunting sector indicate that these values may be considerably higher. Regarding Poland, despite the centralised game resource management system, there are no extensive studies of the economic significance of hunting, and the official data are limited to a few basic indices related to hunting statistics. As indicated by the study results presented in this paper, in Poland, hunting-related expenditures are clearly lower than the European average and, thus, the economic significance of hunting is relatively low in this country. Despite this, it is a hunting community that, as a result of the adopted system solutions, is responsible for the functioning of reasonable game management while significantly affecting the management of the vast majority of rural areas.

Globally, shifting cultivation is known to be an important driver of tropical deforestation. However, in this paper, we argue that it can be sustainably managed if the environmental boundary conditions, laid by the traditional customs and practices, are fully respected. We narrate an empirical study from the Zunheboto district of Nagaland, India, where we deployed a mixed research method to explore the Indigenous and Local Knowledge and Practices (ILKPs) associated with shifting cultivation (aka Jhum), particularly concerning farm-level practices, forest and biodiversity conservation, and disaster risk reduction measures. The research method included analysis of primary data obtained through Focus Group discussions (FGDs), key informant interviews (n = 21), and a questionnaire survey (n = 153) with Jhum farmers from two different age groups, i.e., below 50 years (middle-aged farmers) and above 50 years (older farmers). From the qualitative inquiry, we identified 15 ILKPs, which were then validated from survey responses. We used the Mann–Whitney U test to examine differences in agreement between two groups of framers. Based on this analysis, we conclude that upholding of the ILKPs holds strong potential for the local implementation of several Sustainable Development Goals (SDGs), particularly, SDG-1(No poverty), SDG-2 (Zero hunger), and SDG-15 (Life on land). However, eight of the identified ILKPs showed a statistically significant difference between older and middle-aged farmers, underlining a declining trend. Finally, we suggest suitable policy measures to mainstream ILKPs to balance the trade-offs in food production and biodiversity conservation, and to ensure the future sustainability of Jhum cultivation in the region and beyond.

Costa Rica is widely regarded as a global leader in conservation practices. In the Maquenque National Wildlife Refuge (MNWLR), within Costa Rica's Northern Zone, a strong commitment to conservation has led to protecting highly biodiverse mature forests. However, a significant opportunity to strengthen conservation in this region is being overlooked at a great cost to the local community and environment: the protection of regenerating secondary forests. Secondary forests account for over 50% of global tropical forests and serve vital ecological and cultural functions. Within the MNWLR, many species in the secondary forests provide medicinal value to the rural communities where western medical care is difficult to access. Recent research, however, has shown that secondary forests in Costa Rica are re-cleared within 20 years, before they have accumulated the previously lost biomass and biodiversity. In this paper, we call for conservation and management strategies to incorporate community held knowledge about culturally significant species, and for there to be economic incentives for keeping secondary forests intact and for determining which forests are designated as Protected Areas. We discuss previous research with two trees that are common in secondary forests in the MNWLR (Vismia macrophylla and Pentaclethra macroloba), recognizing that these are some of the many species that have great potential to both the ecological and social communities. While our focus area is in the Northern Zone of Costa Rica, the integration of community use and local knowledge into conservation should be a global priority. [ABSTRACT FROM AUTHOR]

As a leading cause of forest health degradation, non‐native invasive plant species are a key focus for many forest management and conservation efforts. These efforts come at a high price for resource‐limited agencies and organizations making cost‐effectiveness an important objective of invasion response plans. In this paper, we present an approach to guide the prioritization of locations for invasion management using species distribution models that account for the non‐equilibrium of invasive species distributions and use readily available land use data as the primary explanatory variables. This approach takes advantage of the relatively high spatial resolution, as well as the broad, continuous geographic coverage, of land use data to provide results at a landscape scale relevant to practitioners responsible for invasive species management. In our example from northern Virginia, we simultaneously modeled a suite of invasive plant species to identify common indicators of invasion. We found that the proportions of surrounding non‐forested land use types (grasses, crops, and development) were the most common and strongest indicators of invasion risk. These outcomes can guide managers of large protected areas to focus on major divides between forest and non‐forest land over linear disturbances. We also found useful species‐specific traits that can inform specific management actions. Additionally, we demonstrate through a case study how organizations that manage multiple smaller properties can take advantage of the projected distribution maps when considering acquiring or administering properties.

FOREST conservation ,PROPERTY rights ,CIVIL rights ,FORESTS & forestry ,FOREST degradation - Abstract
The past few decades have seen significant changes in the governance of forests in India. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Rights on Forest) Act (FRA), 2006, was a landmark act passed in the Indian Parliament to assign individual property rights over forest resources that have been de facto used by local communities. This paper examines whether the assignment of individual property rights results in positive outcomes for forest conservation using village-level forest patta (forest land title) and census data from Bankura district in West Bengal. Vegetation Continuous Fields data has been used to measure the change in forest cover from 2006 to 2012. The results show that the percentage of forest patta land in the village, distance to markets, the existence of pucca roads, and the presence of forest protection committees (FPCs) are negatively and significantly related to forest degradation, implying improvement in forest conservation outcomes. The presence of tribal people, a larger population, and higher literacy rate are positively associated with forest degradation, meaning that they have an undesirable impact on forest conservation outcomes. The findings of this study strongly suggest that the assignment of individual property rights to both the Scheduled Tribes (STs) living in the forest and Other Traditional Forest Dwellers (OTFDs) under the FRA, 2006, tends to improve forest conservation outcomes. Hence, it is suggested that the distribution of individual forest rights (IFRs) under the FRA may further improve forest conservation outcomes. [ABSTRACT FROM AUTHOR]

Forests as a part of landscape do not fulfil their economic function (timber production) only but a lot of other non-economic functions, especially ecological ones. Both economic and non-economic functions are indisputable and equally important for society. The aim of this paper is to identify current attitudes to forest perceptions by citizens in the Czech Republic. Primary data were obtained by means of a questionnaire research survey which was carried out in 2018. Altogether 824 respondents took part in this survey (n = 824). From the results follows that approximately 70% of respondents visit forest at least three times a month. In connection with this, the relationship between respondents' forest visit frequency and the forest density in the region where they come from was con- firmed. 60% of respondents consider the forest exploitation and forest management to be the most important cause of damage and threats to forest. In relation to forest, 46% of respondents consider forest conservation and protection to be the most important topics. [ABSTRACT FROM AUTHOR]

Mendoza city (Argentina) hosted the VIII Latin American Forestry Congress (CONFLAT) and the V Forestry Congress of Argentina (CFA) in 2023, where relevant issues were addressed, such as climate change, degradation, reforestation, management and forest industry, monitoring, environmental services, social issues, and governance, among others. The objective of this Special Issue was to present the main advances in Forestry Science for Latin-America in the context of changing governance and forest livelihoods for people. The fifteen articles emphasize the interdisciplinary nature of the forest management and conservation, and that multiple variables must be considered to achieve sustainability. The articles come from studies across Southern South-America (Argentina, Brazil, Chile, and Uruguay), and the collaboration of researchers of other countries (México, Canada, and Spain). Articles include research in tropical, Mediterranean and temperate Sub-Antarctic forests. Together, these articles provide a snapshot of new forestry research carried out locally and internationally to bring about beneficial ecological and environmental outcomes in a world facing the challenges of sustainable management and conservation amongst the threats and uncertainty of climate change and environmental degradation responsible for extensive loss of biodiversity and environmental services. We believe that this Special Issue will encourage more inter-disciplinary research focusing on management and conservation of forests. [ABSTRACT FROM AUTHOR]

Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity hotspot, especially for medium to large‐sized species. Here we present a data set from camera trap surveys of medium to large‐sized native mammals (>1 kg) across the Atlantic Forest. We compiled data from 5380 ground‐level camera trap deployments in 3046 locations, from 2004 to 2020, resulting in 43,068 records of 58 species. These data add to existing data sets of mammals in the Atlantic Forest by including dates of camera operation needed for analyses dealing with imperfect detection. We also included, when available, information on important predictors of detection, namely the camera brand and model, use of bait, and obstruction of camera viewshed that can be measured from example pictures at each camera location. Besides its application in studies on the patterns and mechanisms behind occupancy, relative abundance, richness, and detection, the data set presented here can be used to study species' daily activity patterns, activity levels, and spatiotemporal interactions between species. Moreover, data can be used combined with other data sources in the multiple and expanding uses of integrated population modeling. An R script is available to view summaries of the data set. We expect that this data set will be used to advance the knowledge of mammal assemblages and to inform evidence‐based solutions for the conservation of the Atlantic Forest. The data are not copyright restricted; please cite this paper when using the data. [ABSTRACT FROM AUTHOR]

In multifunctional landscapes, expanding economic activities jeopardise the integrity of biodiverse ecosystems, generating conservation-development trade-offs that require multi-stakeholder dialogue and tools to negotiate conflicting objectives. Despite the rich literature on participatory mapping and other tools to reveal different stakeholder perspectives, there is limited evidence on the application of such tools in landscape-scale negotiations. This paper addresses this gap by analysing a participatory mapping process in Ghana's Western Wildlife Corridor, where a community-based landscape governance system called the community resource management area (CREMA) exists. Data from three participatory mapping workshops and focus group discussions with community and institutional actors reveal that increasing demand for food and natural resources and climate change impacts are drivers of landscape degradation, resulting in declining faunal and floral biodiversity and reduced ecosystem services. Meanwhile, community actors prioritise the expansion of farming land, while institutional actors prioritise forest conservation. However, scenario building and participatory mapping helped communicate each other's aims and reach a negotiated consensus. Finally, power relations, cultural and traditional rules, and differences in knowledge affected deliberations and decision-making. We conclude that scenario building and participatory mapping can contribute to an inclusive landscape approach, provided that well-functioning multi-stakeholder platforms are in place and facilitators adequately navigate power imbalances and recognise different kinds and degrees of knowledge.

Understanding factors that influence trade-offs between agricultural expansion and forest conservation is important in managing competing land-use objectives. This paper applies elements of the Analytical Hierarchy Process (AHP) to distinct farming business ownership models in Zambia to gain insights into factors that agricultural land managers take into account when considering land-use trade-off decisions which involve agricultural expansion into natural habitats. Results showed that the market domain was weighted above other domains, followed by the financial domain. When environmental considerations were pitted against other factors such as markets and finance, agricultural land managers were likely to trade off environmental concerns. Furthermore, availability of input subsidies via the agricultural Food Input Support Programme (FISP) influenced the decision to expand, particularly for the small-scale ownership model. This suggests that agricultural policies and strategies aimed at promoting agricultural productivity may require accompanying measures to safeguard forest ecosystems from agricultural expansion. Key differences in the factors influencing expansion decisions were evident among ownership models suggesting that ownership types do have an impact on factors considered. This highlights the need to advance tailored strategies that address differences in priorities and decision making emanating from variations in farming business ownership models.

• Pan-European monitoring on forest dynamics based on Earth Observation data. • Clusters for combined assessment of changes in forest area and canopy density. • Spatial explicit assessment for different settlement types in Europe 2012–2018. • Assessment of protection effects and gaps including characteristic examples. • Variation detection between IUCN protected area management categories. Forest management and conservation can help forests adapt to and minimize the effects of natural and anthropogenic disturbance factors on forest mortality. However, little quantitative information is currently available on the impact of different management and conservation practices on forest dynamics in Europe focusing on forest extent and health simultaneously. Against this background, this paper aims to understand the effectiveness of management and protection practices on two key indicators of forest dynamics under different land use conditions. We analyzed changes in both indicators in Europe between 2012 and 2018, detected spatial explicit mean differences between forest dynamics of protected vis á vis unprotected areas, and examined protected areas of multiple management types. The results show that European forest area increased by 1.2 percentage points pp while canopy density decreased by 2 pp. The average forest area in protected areas increased, but at a slower rate than in their unprotected surroundings indicating no protection effects., In contrast, potential protection gaps can be observed for canopy density changes as density dropped in protected areas by 0.5 pp while it remained stable in unprotected areas. Finally, significant differences between IUCN management and protection categories are quantified against three settlement types and discussed along characteristic examples. In doing so, this paper contributes to the EU Forest Strategy 2030 by providing a robust and spatially explicit monitoring of the effectiveness of managed and protected forests linking observed overall patterns of forest dynamics to conclusions on the role of different management and protection practices.

The work presented in this paper compares the burnt areas in continental Portugal in 2017 and 2018 mapped by three initiatives, namely the Portuguese Institute of Nature and Forests Conservation (ICNF), the Corine Land Cover (CLC) inventory of the Copernicus programme and the European Forest Fire Information System (EFFIS). Then, the Land Use Land Cover (LULC) classes affected by the 2017 burnt areas mapped by ICNF are analysed considering CLC 2018 and the 2018 LULC map produced by the Portuguese National Mapping Agency (Direção Geral do Território) – "Carta de Ocupação do Solo" (COS 2018). To enable a comparison between the classes of both LULC products, a nomenclature was selected and both CLC 2018 and COS 2018 were mapped into the chosen classes. The comparison of the burnt area's extent showed that there are large differences in both area and levels of detail between the analysed data sources. The results regarding the LULC classes affected by the 2017 fires mapped by ICNF show large differences in terms of burnt area in each class as well as the proportion of the burnt areas associated to the classes. This analysis shows that very different results may be reached if different products are used, and therefore a large level of uncertainty is associated with the conclusions achieved with these products.

This paper summarises information on the occurrence of the Common Wombat in the Pilliga Forest, based on 12 years of observations and collation of records from additional sources. The core of the species' distribution in the Pilliga Forest appears to coincide with the most topographically rugged areas, which contain forested hillslopes providing suitable burrow sites and a slightly more mesic microclimate than the broader Pilliga Forest. Outlying records are located where higher quality soils occur in proximity to topographically rugged areas. The paper also notes the regional conservation significance of this edge-of-range population and highlights the local climate refuge value of the south-eastern Pilliga Forest for wombats and other mesic-dependent fauna in the Pilliga Forest.
