Asymmetric Warming and Intensified Extremes Dominate Ugandan Crop Yield Variability (1995–2024): The Primacy of Nocturnal Heat over Precipitation

John Ogwere, Yunsheng Lou, Gerverse Kamukama Ebaju, Stadius Stephen Mtalemwa, Genesis Magara, Nakaana Josiah, Sseruwagi David Daniel & Rhoda Nakabugo · International Journal of Environment and Climate Change · 2025

This study investigates spatiotemporal trends in temperature and precipitation extremes across Uganda (1995–2024) and their impacts on national crop yields, using ERA5-Land reanalysis and FAOSTAT data. Eight core ETCCDI indices were calculated at 0.25° resolution. Monotonic trend...
