This study synthesises existing knowledge on the linkages between Weather and Climate Information Services (WCIS) and Climate-Smart Agriculture (CSA) practices. Specifically, it addresses the following questions: (1) What is the current status of knowledge on WCIS and CSA in the global south, specifically the African continent?, (2) Are WCIS effectively tailored and linked to CSA practices and technologies to improve agricultural water management (AWM) amongst smallholder farmers?, and (3) How can linking WCIS and CSA facilitate the identification, appraisal and prioritization of regionally differentiated and context-specific climate-appropriate technologies and policies that enhance agricultural water management at various levels (field, farm, scheme, and catchment)?
