Climate services can help address a range of climate-sensitive development challenges, including agricultural production and food security. However, generating empirical evidence of impact is challenging. In this paper, we synthesize published evidence of pathways by which climate services contribute to improved food security. A summary of key mechanisms by which climate risk drives food insecurity provides a context for understanding potential climate risk management interventions. Our review of available evaluation literature finds moderately strong evidence that climate services contribute to improvements in food security or its precursors through farmers’ risk management decisions and index-based agricultural insurance; and a weaker body …
