Africa is one of the most vulnerable continents to climate variability and change due to its high exposure to climate shocks and stresses (e.g., droughts) and relatively low adaptive capacities (IPCC Fifth Assessment Report, 2014). In sub-Saharan Africa (SSA) rain-fed agriculture, which is vital for a large percentage of the rural population and contributes significantly to GDP, is particularly vulnerable. Providing decision-makers with timely, accurate information on climate and weather variations can help inform decisions that enhance agricultural production and avoid harvest loss, thereby improving food security, lifting agricultural incomes, and increasing the resilience of farmers to future shocks and stresses. However, the generation and delivery of climate information services (CIS) in SSA is significantly underfunded. To advance our understanding on how to bridge the funding gap this project will: • Develop metrics to assess sustainable and effective provision of CIS by National Meteorological and Hydrological Services (NMHSs) and others, and conduct a baseline assessment of current gaps; • Identify business models for CIS and options to improve the sustainability of NMHSs including collaboration with the private sector; and • Build partnerships, synthesis knowledge, and ensure uptake of lessons.
