Increasing potential evapotranspiration despite non-significant rainfall trends: a 35-year hydroclimatic analysis and assessment of farmer perceptions in Southern Ethiopia
Rainfed smallholder agriculture in sub-Saharan Africa is increasingly exposed to rising atmospheric evaporative demand and hydroclimatic variability, even where long-term annual precipitation totals show no significant directional change. This study examines 35-year hydroclimatic variability and farmer-reported climate...
