Soil Erosion under Future Climate Change Scenarios in a Semi-Arid Region

The Mediterranean Region is presumed to be one of the locations where climate change will have most effect. This impacts natural resources and increases extent severity disasters, in general, soil water erosion particular. focus this research was assess how might affect rate a watershed High Atlas Morocco. For purpose, high-resolution precipitation temperature data (12.5 × 12.5 km) were collected from EURO-CORDEX regional model (RCM) simulations for baseline period, 1976–2005, future periods, 2030–2060 2061–2090. In addition, three maps created slopes, land cover, geology, while observed process catchment determined following field observations. potential (EPM) then used variations on rate. Until end 21st century, results showed decrease annual −32% −46% under RCP 4.5 periods 2061–2090, respectively, −28% −56% 8.5 same large increase +2.8 °C +4.1 scenario, +3.1 +5.2 scenario respectively. aforementioned changes are anticipated significantly rate, by +97.11 m3/km2/year 2060, +76.06 2090, scenario. predicts rise +124.64 period 2030–2060, but drop −123.82 2060–2090.
