Abstract Drylands in sub-Saharan Africa are strongly affected by the impacts of climate change. Temperature increases, changes rainfall patterns, and land degradation pose serious threats to food security, health, water availability region. The increase livelihood insecurity can turn trigger migration as a way adapt or cope with stress. Based on 89 original case studies, this study uses review ...

Abstract Drylands are ecohydrologically-coupled ecosystems whose functioning depends on the interplay between hydrological connectivity runoff source areas and capacity of vegetation to retain water fluxes associated resources. In this study we present a new easily applicable methodology for ecohydrological characterization dryland ecosystem grounded in balance these two strongly interrelated p...

Dryland ecosystems account for ca. 27% of global soil organic carbon (C) reserves, yet it is largely unknown how climate change will impact C cycling and storage in these areas. In drylands, soil C concentrates at the surface, making it particularly sensitive to the activity of organisms inhabiting the soil uppermost levels, such as communities dominated by lichens, mosses, bacteria and fungi (...

Water-use efficiency (WUE), defined as the ratio of net primary productivity (NPP) to evapotranspiration (ET), is an important indicator to represent the trade-off pattern between vegetation productivity and water consumption. Its dynamics under climate change are important to ecohydrology and ecosystem management, especially in the drylands. In this study, we modified and used a late version o...

Abstract Precipitation is crucial for life and the ecological environment in Asian drylands. This study investigated precipitation trends drylands previous four decades simulated its possible linkage with snow cover reduction over Tibetan Plateau. The results show that has been increasing contributing to wetter conditions can be attributed deepened quasi-stationary wave trough around Lake Balkh...
