Abstract Freshwater biodiversity, from fish to frogs and microbes macrophytes, provides a vast array of services people. Mounting concerns focus on the accelerating pace biodiversity loss declining ecological function within freshwater ecosystems that continue threaten these natural benefits. Here, we catalog nine fundamental ecosystem biotic components indigenous provide people, organized into three categories: material (food; health genetic resources; goods), non‐material (culture; education science; recreation), regulating (catchment integrity; climate regulation; water purification nutrient cycling). If is protected, conserved, restored in an integrated manner, as well more broadly appreciated by humanity, it will contribute human well‐being our sustainable future via this wide range associated nature‐based solutions future.

The study examines the complex dynamics of changes in LULC over three decades, focused on years 1992, 2002, 2012, and 2022. research highlights significance comprehending these alterations within framework environmental socio-economic consequences. land use cover (LULC) have significant far-reaching effects ecosystems, biodiversity, human livelihoods. This offers useful information for politicians, conservationists, urban planners by examining historical patterns forecasting future changes. utilized a Multilayer Perceptron Neural Network (MLP-NN), well-known machine learning technique that excels at collecting intricate patterns. model's design had layers: input, hidden, output. model underwent 10,000 iterations during its training process, thorough statistical analysis was conducted to assess impact each driving component. MLP-NN demonstrated impressive performance, with skill measure 0.8724 an accuracy rate 89.08%. estimates 2022 verified comparing them observed data, ensuring reliability. Moreover, presence evidence likely found be factor substantial model. effectiveness accurately predicting LULC. exceptional proficiency make it powerful tool forecasts.

Comparing and evaluating global climate datasets their effect on model performance in regions with limited data availability has received little attention ecological modeling studies so far. In this study, we aim at comparing the interpolated dataset Worldclim 1.4, which is most widely used studies, quasi-mechanistical downscaled Chelsa, as well latest versions 2.1 Chelsa 1.2, regard to suitability for studies. To evaluate of these meso-scale, niche Betula utilis Nepal modeled under current future conditions. We underline differences regarding methodology bias correction between highlight potential drawbacks models remote high mountain regions. Regarding prediction plausibility climatic conditions, Chelsa-based significantly outperformed Worldclim-based models, however, version contains partially inherent distorted precipitation amounts. This study emphasizes that unmindful usage may have severe consequences treeline species high-altitude projections, if based flawed predictions. The results illustrate inevitable need interdisciplinary investigations collaboration scientists ecologists enhance climate-based quality meso- local-scales by accounting local-scale physical features temporal spatial resolution.

Human–wildlife conflict in the roof of the world: Understanding multidimensional perspectives through a systematic review

Ecology and Evolution, Год журнала: 2021, Номер 11(17), С. 11569 - 11586

Опубликована: Авг. 2, 2021

Abstract Human–wildlife conflicts have intensified by many folds and at different levels in recent years. The same is true the case of Hindu Kush Himalaya (HKH), roof world, a region known for its wealth biodiversity. We present systematic literature review (SLR) using search, appraisal, synthesis, analysis (SALSA) framework; spatial network analysis, we employed VOSviewer software. review—covering 240 peer—articles within span 27 years (from 1982 to 2019)—revealed that last decade, there was 57% increase publications but with disproportionate geographical thematic focus. About 82% research concentrated on protected areas large carnivores mega herbivores played big role such conflicts. 53% studies were based questionnaires, main driver reported habitat disturbance animals due land‐cover change, urbanization, human population. On management front, use traditional protection techniques like guarding fencing. Our 681 keywords revealed prominent focus ‘human‐wildlife conflict,’ ‘Nepal,’ ‘Bhutan,’ ‘Snow Leopard,’ ‘Leopard’ indicating issue linked these species countries. involvement 640 authors from 36 countries indicates increasing interest, Nepal India are playing key roles region. As conducted, while it showed regional variations, conspicuous limitations terms having transboundary Thus, particular attention ought be paid building partnerships improving interventions; also pressing need understand patterns human–wildlife convergence, especially involving meso‐mammals.

Knowledge Priorities on Climate Change and Water in the Upper Indus Basin: A Horizon Scanning Exercise to Identify the Top 100 Research Questions in Social and Natural Sciences

Earth s Future, Год журнала: 2022, Номер 10(4)

Опубликована: Март 24, 2022

Abstract River systems originating from the Upper Indus Basin (UIB) are dominated by runoff snow and glacier melt summer monsoonal rainfall. These water resources highly stressed as huge populations of people living in this region depend on them, including for agriculture, domestic use, energy production. Projections suggest that UIB will be affected considerable (yet poorly quantified) changes to seasonality composition future, which likely have impacts these supplies. Given how directly indirectly communities ecosystems dependent growing pressure them due ever‐increasing demands, climate change pose adaptation challenges. The strong linkages between hydroclimate, cryosphere, resources, human activities within a multi‐ inter‐disciplinary research approach integrating social natural/environmental sciences is critical successful ongoing future hydrological change. Here we use horizon scanning technique identify Top 100 questions related most pressing knowledge gaps priorities natural UIB. margins current thinking investigation clustered into 14 themes, covering three overarching topics “governance, policy, sustainable solutions”, “socioeconomic processes livelihoods”, “integrated Earth System processes”. Raising awareness cutting‐edge opportunities hopefully encourage researchers, funding bodies, practitioners, policy makers address them.

Ecosystem services research trends in the water tower of Asia: A bibliometric analysis from the Hindu Kush Himalaya

Ecological Indicators, Год журнала: 2020, Номер 121, С. 107152 - 107152

Опубликована: Ноя. 12, 2020

The study presents the first comprehensive overview of ecosystem services (ES) research from Hindu Kush Himalaya (HKH), a region often referred to as 'water tower Asia'. Through systematic literature search, we consolidated 439 peer-reviewed journal articles related in HKH. A bibliometric analysis was carried out examine temporal trend, geographical distribution, coverage, keywords used, authorship patterns, and collaboration networks ES on region. results showed an increasing trend publication HKH, with nearly 62 per cent being published just last five years. Most has been China, followed by Nepal India. Among 166 scholarly journals publishing Ecosystem Services Sustainability are most-used, Science Total Environment. identified total 1,460 used ES. them, 'ecosystem services' is most commonly 'China', 'Nepal', conservation', 'biodiversity.' revealed that 1,386 authors, 1,000 co-authored publications. top authors region; however, they either affiliated international organization or based developed countries. Research institutions 56 countries have networked conduct collaborative so far. Although China highest number publications, principal collaborator widest country network. existing focuses biophysical elements services, very few studies covering its social political aspects management services. As HKH contiguous shared eight countries, there need for regional analyses Our concludes multidisciplinary concept, into it requires between multiple actors varied disciplines, greater emphasis science, together sciences, more holistic understanding. Furthermore, important include local context issues avoid dominance perspectives marginalization concerns.
