Geospatial Assessment of Climate Resilience Strategies in Sorghum Cultivation across Semi-Arid Landscapes
Author(s): Ricardo Rojas
Abstract: Sorghum (
Sorghum bicolor L. Moench) is the world’s fifth most important cereal crop and a critical food and fodder source in semi-arid regions across Africa, Asia, and the Americas. Global climate change threatens sorghum production with increasing temperature extremes, erratic rainfall, and prolonged droughts. This study develops a geospatial framework to assess climate resilience strategies in sorghum cultivation globally using open-source Earth observation datasets and international production statistics. We integrate CHIRPS rainfall data (CHIRPS), ERA5 reanalysis climate fields (ERA5), MODIS vegetation indices (NASA MODIS), SMAP soil moisture (NASA SMAP), and FAOSTAT and USDA-FAS global production statistics (FAOSTAT; USDA PSD). Our results highlight spatial heterogeneity in exposure and sensitivity across semi-arid zones: Sub-Saharan Africa remains highly rainfall-dependent, while North America exhibits partial decoupling of yields from climate due to advanced breeding and management. Adaptive strategies—early-maturing hybrids, soil-water conservation, and integration of sorghum as silage—emerge as globally relevant practices for enhancing resilience. This global synthesis provides a blueprint for climate-smart monitoring of sorghum production in semi-arid systems.
