The report analyzes the intersection of climate threats and socio-economic vulnerabilities in the Yaque del Sur basin, the Dominican Republic's third-largest basin. It finds that the region faces severe water deficits and high vulnerability due to poverty and dependence on climate-sensitive agriculture. Projected climate trends include rising temperatures and decreasing precipitation, which could lead to an annual water deficit of 390 million m3 by 2050. The document identifies critical gaps in institutional coordination between disaster risk management and climate change adaptation bodies. To mitigate these risks, it recommends seven priority actions, including switching to drought-resistant crops like sorghum and mangoes, increasing irrigation efficiency from 20% to 45%, and implementing payment for ecosystem services to promote reforestation in the upper basin.
