With the impact of climate change and implementation “Grain-for-Green” ecological restoration project, dynamics water heat transport storage in Loess Plateau (LP) have changed substantially. However, studies on vulnerability LP ecosystem response to are less concerned. Based normalized difference vegetation index (NDVI) gross primary production (GPP), this study assessed spatial (EV) during 200...
Abstract In a changing climate, drought risk and vulnerability assessments are becoming increasingly important. Following the global call for proactive management, progressively taking their stage in research community. As manifestation of is dependent on social, ecological, hydroclimatic context which it occurs, identifying factors relevant specific climatological ecological regions may improv...
Species distribution models (SDMs) are commonly used to assess potential climate change impacts on biodiversity, but several critical methodological decisions are often made arbitrarily. We compare variability arising from these decisions to the uncertainty in future climate change itself. We also test whether certain choices offer improved skill for extrapolating to a changed climate and wheth...
West Africa has been described as a hotspot of climate change. The reliance on rain-fed agriculture by over 65% of the population means that vulnerability to climatic hazards such as droughts, rainstorms and floods will continue. Yet, the vulnerability and risk levels faced by different rural social-ecological systems (SES) affected by multiple hazards are poorly understood. To fill this gap, t...
Abies nephrolepis is a climate-vulnerable species that inhabits high mountains in the Baekdu–Daegan range and distributed along southern limit line South Korea, making it suitable for climate change research. This study aimed to observe spatial distribution changes according scenarios using models nephrolepis, analyze relationship between various environmental factors density, contribute future...
At present, climate change has brought huge challenges to vegetation and ecosystems. As the Qinghai-Tibet Plateau (QTP) is a sensitive area of global change, dynamic assessment its ecological vulnerability very important. In order better quantify relative size QTP, this study starts from background characteristics process ecosystem, by fitting index net primary productivity (NPP) temperature, p...
