Climate change and variability can severely constrain the productivity of pastoral herds by reducing water availability, forage production and quality, and hence the carrying capacity of rangelands. In particular, the risk of heavy livestock losses suffered during recurrent severe droughts associated with climate change and variability presents one of the most serious threats to pastoral livestock keepers.

This paper illustrates how weather derivatives indexed to forecasts of famine can be designed and used by operational agencies and donors to facilitate timely and reliable financing, for effective emergency response to climate-based, slow-onset disasters such as drought. We provide a general framework for derivative contracts, especially in the context of index insurance and famine catastrophe bond, and show how they can be used to complement existing tools and facilities in drought risk financing through a risk-layering strategy.
