In many low-income countries, agriculture is mostly rain-fed and yields highly depend on climatic factors. Furthermore, farmers have little access to traditional crop insurance, which suers from high information asymmetry and transaction costs. Insurances based on meteorological indices could ll this gap since they do not face such drawbacks. However their implementation has been slow so far. In this article, we rst describe the most advanced projects that have taken place in developing countries using these types of crop insurances.
The authors then describe the methodology that has been used to design such projects, in order to choose the meteorological index, the indemnity schedule and the insurance premium. We nally draw an agenda for research in economics on this topic. In particular, more research is needed on implementation issues, on the assessment of benets, on the way to deal with climate change, on the spatial variability of weather and on the interactions with other hedging methods.
