To help transition from reactive to proactive drought management, and in the absence of a cross-sectoral coordinating mechanism around drought investment prioritization, the World Bank has put together a process for developing a Drought Risk and Resilience Assessment (DRRA). The DRRA methodology includes reference to Nature-based Solutions (NBS) as an option to make countries more resilient to droughts. However, how these types of interventions can increase efficiency of World Bank projects, how they can be identified, how impacts can be assessed, and which challenges need to be addressed to implement NBS is not yet addressed sufficiently. This knowledge gap will be addressed by (i) Development of factsheets of existing NBS interventions to reduce drought risks for water services for drink water supply, for agriculture, for energy or other economic sectors that depend on water, and (ii) Developing an inventory of existing tools to identify effective NBS for drought resilience and assess their potential impact.
