The Yaque del Sur watershed in the Dominican Republic is already under severe water stress. The population of the area is much poorer than the national average and livelihoods are dependent on cash crops and subsistence agriculture. Cyclones, storms, floods and droughts regularly damage crops and infrastructure in the watershed. This report highlights how climate change is likely to cause additional stress to the vulnerable area. It notes that current coping strategies may be insufficient to deal with future climate risks and it presents issues that efforts to manage climate risks in Yaque del Sur should focus on, including: selecting crop varieties that use less water; climate-proofing access roads; building water reservoirs for domestic and agricultural use; establishing agroforestry and payment for ecosystem services systems to promote reforestation in the upper watershed; increasing irrigation efficiency; and improved monitoring and accessibility of climate data.
