The document analyzes climate vulnerability in the Bacia do Jacuípe, a poor region in the Brazilian Sertão, where temperatures have risen by approximately 2 °C and rainfall has decreased by about 350 mm since 1962. This environmental shift has led to a decline in average milk productivity, contrasting with overall increases in Bahía and Brazil. To address this, the Adapta Sertão coalition tested various farm-level interventions, finding that efficient irrigation systems and balanced animal diets can reduce production's dependence on climate, suggesting these are viable adaptation strategies for larger-scale implementation in semi-arid regions.
