Rainfall gauges are always sparse in the arid and semi-arid areas of Northwest China, which makes it difficult to precisely study the characteristics of drought at a large scale in this region and similar areas. This study used the TRMM (The Tropical Rainfall Measuring Mission) multi-satellite precipitation data to study the spatial-temporal evolution of drought in the Loess Plateau based on the…

Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting in these environments is generally discouraged due to the large water consumption by trees, but this view may neglect their potential positive impacts on water availability. The effect of trees on soil hydraulic properties linked to groundwater recharge is poorly understood. In this study, we…

Findings from this study indicate that tree cover, daily rainfall intensity, and the interaction between the two strongly influenced soil water dynamics in an agroforestry parkland in semiarid West Africa. Tropical regions are likely to experience more intense rainfall events in the future. Such an increase in rainfall intensities will affect soil and groundwater recharge, with…

Vast swathes of land, from Africa to the Middle East, are being left useless by climate shifts and human pressures such as deforestation, mining and farming, threatening to hike migration and conflict. The accelerating damage could cost the global economy a staggering $23 trillion by 2050 - and rich countries as well as poor will pay the price. Interview with Ibrahim Thiaw
