مستخلص: The efficacy of simulating the ecological networks of landscapes has been examined using a wide range of modelling techniques, although it has not yet been fully investigated. In order to prepare for conservation and identify suitable corridors for wildlife species, this study aims to model and predict landscape ecological networks in 2035 for the Malayan tapir (Tapirus indicus) at Chini-Bera Forest Complex, Pahang. It was parameterized using changes between 1988 and 1999 and verified with land use in 2020 using Land Change Modeller (LCM)-Markov Chain models. The year 2035 was then simulated for land use growth using these models. Then, utilizing integrated circuit models, connectivity analysis, and least cost analysis, the simulated 2035 land was determined to identify the potential corridors. Utilizing potential corridors and the least cost pathways for Tapir at the patch sites, the integrated models enabled for the assessment of connectivity for Tapir. The connectivity of forest areas may be improved by putting the designated routes through changes. This study illustrates how combining models can enhance ecological networks in forest complexes and shows how important such models are for biodiversity preservation and forest planning.

مستخلص: This study compared the ecological effects on forest conservation before and after changes in Brazilian forest protection, taking a case study of a water source area in Diadema, the municipality with the highest demographic density in São Paulo State. We also evaluated compliance with the laws (Forest Code—FC and Native Vegetation Protection Law—NVPL), considering the reality of land use and land cover (LULC) in the year before the new law NVPL. We created LULC maps of legal scenarios for both laws analyzed based on landscape metrics of optimal resource availability (ORA), distance from the nearest neighbor (ENN), and anthropogenic edge frequency and length (ESD and ED). Our findings revealed that changes to some technical criteria in the NVPL reduced the quantity (220–105 ha) and quality (ORAFC = 0.02 and ORANVPL = 0.005) of Diadema protected forests and altered their neighborhood relationships, stronger influenced by human-modified fields as agents of fragmentation and pressure for further disturbances. The results indicate that the new law does not substantially increase compliance (30–35%), but if it has full compliance, landscape connectivity could be improved (ENNFC = 8.6 and ENNNVPL = 11.2). Our technique to create a LULC map of legal expectation, combined with the application of selected landscape metrics, proves valid for understanding the changes in Brazilian expectative protection regarding forest conservation.

الملخص (بالإنجليزية): In recent years, Togo's protected areas have been subject to a worrying process of anthropisation. This has led to a decline in forest ecosystems, their biodiversity and their functions. The general objective of this study is to assess the state of conservation of the classified forest of Amou-Mono between 1986 and 2021. More specifically, it aims to: (i) characterize the dynamics of land use from 1986, 2000, 2013 and 2021 and, (ii) assess the impact of changes in land use on the potential for carbon sequestration. A multi-date classification of Landsat images for the years 1986, 2000, 2013 and 2021 made it possible to quantify and assess changes in occupation. The dynamics of land use between 1986 and 2021 is mainly reflected by a regression of dense/riparian forests (81.40%) and open forests/wooded savannahs (67.79%) and the progression of wooded/shrubby Savannah (172.93%). Anthropogenic formations: Fields/fallow and Agglomerations/Bare soils, absent in 1986, occupy in 2021 respective proportions of 38.1 % and 2.19%. Human activities, particularly logging and agricultural clearing, are causing fragmentation and regression of forest ecosystems. Unless action is taken to reverse the trend, the conservation of biodiversity and ecosystem functions in this classified forest will be increasingly threatened. [ABSTRACT FROM AUTHOR]

Abstract (French): Les aires protégées du Togo connaissent un phénomène d'anthropisation inquiétante ces dernières années entrainant la régression des écosystèmes forestiers, leur biodiversité et leurs fonctions. Cette étude a analyser la dynamique spatio-temporelle de la forêt classée d'Amou-Mono entre 1986 et 2021. Une classification multi des images Landsat des années 1986, 2000, 2013 et 2021 a permis de quantifier et d'apprécier les changements d'occupations. La dynamique de l'occupation du sol entre 1986 et 2021 est traduite essentiellement par une régression des Forêts denses/riveraines (81,40 %) et des Forêts claires/Savanes boisées (67,79 %) et la progression des savanes arborées/arbustives (172,93 %). En 2021, les formations anthropogènes Champs/jachères et Agglomérations/Sols nus, qui n'existaient pas en 1986, représentent respectivement 38,1 % et 2,19 % du total. La fragmentation et la régression des formations forestières sont dues à des activités anthropiques, notamment l'exploitation forestière et les défrichements agricoles. Ceci constitue une menace croissante pour la conservation de la biodiversité et les fonctions écosystémiques dans cette forêt classée si aucune mesure n'est prise pour inverser les tendances.

مستخلص: Above-ground biomass (AGB) is affected by numerous factors, including topography, climate, land use, or tree/forest attributes. Investigating the distribution and driving factors of AGB within the managed forests in Nepal is crucial for developing effective strategies for climate change mitigation, and sustainable forest management and conservation. A total of 110 field plots (circular 0.02 ha plots with a 9 m radius), and airborne laser scanning (ALS)-light detection and ranging (LiDAR) data were collected in 2021. The random forest (RF) model was employed to predict the AGB at a 30 m × 30 m resolution based on 32 LiDAR metrics derived from ALS returns. The study assessed the relationships between the AGB distribution and nine independent variables using statistical techniques like the random forest model and partial dependence plots. Results showed that the mean value of the estimated AGB was 120 tons/ha, ranging from 0 to 446.42 tons/ha. AGB showed higher values in the northeast and southeast regions, gradually decreasing towards the northwest. Land use land cover, mean annual temperature, and mean annual precipitation were identified as the primary factors influencing the variability in AGB distribution, accounting for 64% of the variability. Elevation, slope, and distance from rivers were positively correlated with AGB, while proximity to roads had a negative correlation. The increase in precipitation and temperature contributed to the initial rise in AGB, but beyond a certain lag, these variables led to a decline in AGB. This study showed the efficiency of the random forest model and partial dependence plots in examining the relationship between the AGB and its driving factors within managed forests. The study highlights the importance of understanding the AGB driving factors and utilizing LiDAR data for informed decisions regarding the region's sustainable forest management and climate change mitigation efforts.

مصطلحات جغرافية: PERU

مستخلص: This study contributes to the relatively scarce literature evaluating household-level outcomes of collective agreements. We examine participation in and anticipation effects of two collective, incentive-based initiatives in Ucayali, Peru. The first initiative is a local REDD+ project, the second is Peru's National Forest Conservation Program (NFCP). Both initiatives were evaluated at an early stage of implementation, thus any effects are characterized as anticipation effects. We first examine the determinants of participation in the initiatives and find that household participation is negatively associated with agricultural income and positively associated with market access and previous experiences with external initiatives. Next, we use quasi-experimental methods and self-reflexive evaluations to examine impacts on land use and livelihoods. The results show no evidence of anticipation effects on income or land use. Self-reflexive evaluations indicate, however, that a total of 82% of the NFCP participating households perceive a positive effect on wellbeing, while only 39% of participants in REDD+ perceive a positive effect. The differences in perceptions of the two initiatives is attributed to design and implementation factors, including delayed payments, lack of transparency, and limited local input. The study demonstrates the value of self-reflexive evaluations for identifying intangible effects on wellbeing of conservation initiatives. [ABSTRACT FROM AUTHOR]

الملخص (بالإنجليزية): Anthropogenic climate change, land use modifications, and alien species invasions are major threats to global biodiversity. Protected areas (PAs) are regarded as the cornerstone of biodiversity conservation, however, few studies have quantified the vulnerability of PAs to these global change factors together. Here, we overlay the risks of climate change, land use change, and alien vertebrate establishment within boundaries of a total of 1020 PAs with different administrative levels in China to quantify their vulnerabilities. Our results show that 56.6% of PAs will face at least one stress factor, and 21 PAs are threatened under the highest risk with three stressors simultaneously. PAs designed for forest conservation in Southwest and South China are most sensitive to the three global change factors. In addition, wildlife and wetland PAs are predicted to mainly experience climate change and high land use anthropogenetic modifications, and many wildlife PAs can also provide suitable habitats for alien vertebrate establishment. Our study highlights the urgent need for proactive conservation and management planning of Chinese PAs by considering different global change factors together. [ABSTRACT FROM AUTHOR]

Abstract (Chinese): 与人类活动密切相关的气候变化、土地利用改变和外来物种入侵是当今全球变化时代影响生物多样性的重要因子。自然保护区被视为生物多样性保育的基石，然而，很少研究评估自然保护区面对这些致危因子的脆弱性。本文根据未来预测至2050年的气候变化和土地利用情景，结合1400余种已引入中国大陆的外来脊椎动物建群适宜栖息地模拟，评估了1020个具有明确地理边界和保护功能信息的中国大陆自然保护区对未来三个致危因子的脆弱性。研究表明:56.6%的保护区将面临至少一种风险因子，21个保护区将同时面对三种风险因子的挑战，中国西南和华南地区的森林类型保护区将可能对三种风险因子最为敏感。此外，野生动物和湿地保护区也将面临气候变化和生境干扰的威胁，同时许多野生动物保护区也具有较多的适宜外来脊椎动物建群的栖息地。本研究结果建议:应综合考虑未来气候变化、土地利用改变和外来物种入侵对生物多样性的潜在威胁，对中国自然保护区进行及时的前瞻性保护管理规划。 [ABSTRACT FROM AUTHOR]

مستخلص: The effects of various strategies aimed at simultaneously promoting environmental conservation and human development are closely related to sustainable development regionally and globally. However, although the effects of many such strategies have been evaluated by ecologists and sociologists separately, their ability to simultaneously meet these two anticipated goals (i.e., environmental conservation and human development) at the fine spatial scale remains unclear. To answer this fundamental but crucial question, incorporating household and forest change data, we concurrently estimated the ecological and socioeconomic effects of two world-renowned Payment for Ecosystem Services (PES) programs (i.e., the Nature Forest Conservation Program, the Grain to Green Program) and nature-based tourism in 30 protected areas across 8 provinces in China. Here we showed a trade-off between the ecological and economic effects of two PES programs, while synergistic effects exist in the ecological and economic benefits of tourism. Attributes of household and protected areas significantly influenced economic and environmental benefits as well. Our research provides new insights into the complex effects of PES programs and tourism, and crucial information to support their adequate and sustainable implementation in China and the rest of the world. Significance Statement: This work answers a fundamental but crucial question, that is, whether the policies commonly advocated to incorporate environmental conservation and human development can yield positive effects both for conservation and economic development. Our evaluation is also timely to inform some shortness (i.e., negligible economic effects, or the lack of expected positive economic benefits) and provides new insights (e.g., the implication of households and protected-areas attributes in conservation and economic outcomes) of Payment for Ecosystem Services (PES) programs and the complex effects of instruments in the context of multiple policies, particularly given the upcoming 2030 deadline for achieving the Sustainable Development goals (SDGs). We expected that implications in this study can provide important lessons for these two instruments, other PES programs, and other conservation and development instruments to support their adequate and sustainable implementation in China and beyond and to contribute to the achievement of relevant SDGs in the remaining years.

مصطلحات جغرافية: GEORGIA

مستخلص: Working forest conservation easements (WFCEs) are increasingly used to protect working forests. However, their attributes such as forest management activities, landowner goals, landscape features, and land uses vary significantly. Understanding the trends and patterns in these attributes is essential to comprehend the conservation, ecological, and economic implications of WFCEs. This study analyzed the spatial relationships of easement attributes by examining WFCEs managed by three easement-holding organizations in Georgia, by text-mining the attributes from the contracts and the baseline reports. Results revealed a strong spatial correlation in the distribution of WFCEs concerning landowners' goals, land use types, recreational opportunities, and forest management activities. Similarly, significant clusters of WFCEs were identified near state-protected forestlands to maintain habitat connectivity. The findings help understand the concentrations and variations of easement attributes and serve as a working guide to landowners and easement-holding organizations to locate and strategically target easements in Georgia.

مستخلص: Transfer of development rights (TDR) programs are land preservation programs that promise to conserve land in its current use by allowing landowners to sell development rights on their parcels. Using Montgomery County (MD) as an example, I examine how development patterns evolve under a TDR program and how well this program delivers its promise of permanent preservation. Montgomery County is a national model as one of the most successful TDR programs in the United States. After matching the digitized TDR transaction records with land use/land cover maps, I found a clear effect of the program on encouraging agricultural land and forest preservation. However, scattered development patterns have also emerged in the TDR sending area. The TDR program showed promising effects on preserving agricultural land and forest but also insufficiency in advancing desirable development patterns and ensuring permanent conservation. Planners should be cautious about the putative advantages of land preservation through TDR programs. Such efforts may not engender the desired outcomes. Owing to the unbridled pressure for development in large metropolitan areas, attempting to maintain land for agricultural and forest use perpetually in their suburbs is financially challenging. Thus, planners should enhance their endeavors to track the actual preservation achieved by TDR programs and discern whether sprawling patterns start to emerge in the TDR sending areas. I also discuss specific design features that planners can use in land preservation programs to improve their effectiveness. [ABSTRACT FROM AUTHOR]

مستخلص: Affem Boussou community forest (AFC) abounds in important biological resources. This study, which contributes to its better management, examines the spatiotemporal dynamics of the vegetation and its ecological and structural characteristics to propose a zoning plan for said forest. The analysis of the spatiotemporal dynamics of land use in the AFC from Google Earth images of 2015, 2018, and 2021 revealed a regressive trend of formations: crops and fallows (−33.98%), dense dry forests (−7.92%), gallery forests (−3.46%), plantations (−100%), grassy savannahs, and meadows (−18.84%), except for tree/shrub savannahs (484.23%). The floristic inventory identified 163 species divided into 129 genera and 55 families. Fabaceae (14.02%), and Combretaceae (10.55%) are the most represented families. Anogeissus leiocarpa (5.19%) and Vitellaria paradoxa (4.72%) are the most frequent species. We note the dominance of individuals of small diameters. The regeneration potential of the AFC is 64 feet/ha due to 21 feet/ha of suckers, 29 feet/ha of seedlings, and 14 feet/ha of shoots. As a zoning plan, the AFC was subdivided into four zones: the agroforestry zone (18.80%), the sustainable production forest zone (42.22%), the buffer zone (11%), and the biological conservation zone (28%). These results constitute a scientific basis for testing ecological indicators of the sustainable management of community forests in Togo. [ABSTRACT FROM AUTHOR]
