Climate Change as a Double-Edged Sword: Exploring the Potential of Environmental Recovery to Foster Stability in Darfur, Sudan

Climate, Journal Year: 2025, Volume and Issue: 13(3), P. 63 - 63

Published: March 18, 2025

The Darfur conflict, which emerged in the early 21st century, represents a multifaceted crisis driven by socio-political and environmental factors, with resource scarcity, exacerbated climate change, playing pivotal role intensifying tensions between agricultural pastoral communities. While change is typically associated adverse outcomes, an analysis of data spanning four decades (1980–2023) reveals contrasting trend increased precipitation, enhanced vegetation, decreased drought frequency recent years. This research explores potential these positive changes to mitigate resource-based conflicts foster political stability as improved conditions are posited create foundation for conflict resolution sustainable peacebuilding. present study integrates trends Enhanced Vegetation Index (EVI) Standardized Precipitation Evapotranspiration (SPEI) examine shifts. EVI data, derived from Moderate Resolution Imaging Spectroradiometer (MODIS) at 250 m resolution, was used assess large-scale vegetation patterns arid semi-arid landscapes. Autoregressive Integrated Moving Average (ARIMA) model employed forecast future precipitation scenarios up year 2034, enhancing understanding long-term climatic trends. Data processing utilized advanced tools, including Google Earth Engine (GEE), ArcGIS Pro (version 3.4), R software 4.3.2). findings reveal significant (33.19%) improvement natural cover 2000 2023, degraded unchanged areas accounting 1.95% 64.86%, respectively. finding aligns marked increase annual reduction intensity over period. Historical SPEI showed persistent events 1980 2012, followed notable decline severity 2013 2024. projections suggest stable trend, potentially supporting further recovery region. These improvements preliminarily linked climate-change-induced increases reductions severity. study’s contribute nuanced interplay dynamics Darfur, offering actionable insights policy interventions aimed fostering peace resilience

Spatiotemporal Changes in Vegetation Cover during the Growing Season and Its Implications for Chinese Grain for Green Program in the Luo River Basin

Forests, Journal Year: 2024, Volume and Issue: 15(9), P. 1649 - 1649

Published: Sept. 19, 2024

The Grain for Green Program (GFGP) plays a critical role in enhancing watershed vegetation cover. Analyzing changes cover provides significant practical value guiding ecological conservation and restoration vulnerable regions. This study utilizes MOD13Q1 NDVI data to construct the Kernel Normalized Difference Vegetation Index (kNDVI) analyzes spatiotemporal evolution future trends of from 2000 2020, covering key periods GFGP. innovatively combines optimal parameter geographic detector with constraint lines comprehensively reveal nonlinear constraints, intensities, thresholds imposed by various driving factors on kNDVI. results indicate that following: (1) Luo River Basin increased significantly between noticeable increase percentage high-quality vegetation. Spatially, followed pattern being “high southwest low northeast”, 73.69% region displaying improved conditions. Future degradation is predicted threaten 59.40% region, showing continuous or declining trend. (2) primary are evapotranspiration, elevation, population density, geomorphology type, temperatures GDP secondary factors. Dual-factor enhancement was observed interactions among factors, evapotranspiration density having largest interaction (q = 0.76). (3) effects exhibited patterns, existing hump-shaped concave-waved types. stability kNDVI 40.23% areas showed moderate high fluctuations, most fluctuations low-altitude high-temperature areas, as well those impacted dense human activities. (4) By overlaying classifications GFGP priority reforestation totaling 68.27 km2 were identified. findings can help decisionmakers optimize next phase effective regional management.

Impacts of Intensified Human Activity on Vegetation Dynamics in the Qinba Mountains, China

Forests, Journal Year: 2024, Volume and Issue: 15(9), P. 1561 - 1561

Published: Sept. 5, 2024

The Qinba Mountain range is a typical climate-sensitive and ecologically fragile region. Monitoring of vegetation dynamics crucial for ecological protection achieving sustainable development goals. Various mutation-detection methods, along with slope analysis, hot-spot residual were used to examine changes in the Normalized Difference Vegetation Index (NDVI) during growing non-growing seasons over 41 years distinguish relative effects drivers. This revealed four key findings. (1) NDVI increased at 0.02 decade−1, mutation points 2006 growing-season 2007 non-growing-season NDVI. (2) trend changed markedly point. After point, was impacted more by human activity than climate change. hot cold spots rate change location season; season, it shows an obvious north–south distribution. (3) spatial patterns drivers this In before collectively enhanced ca. 81.3% region; after value declined 59.9% area, became dominant driver area formerly dominated both factors combination. areas where promoted growth decreased 12.6% those alone 11.1%, whereas affected only 11.6%. (4) Before contributed >60% western Qinling region, contributing other areas. exerted stronger influence change, enhancing >80% reducing it.
