Cash transfer programmes are increasingly being used to combat poverty and hunger as well as to shape the human capital of future generations. Even though most of these programmes are not explicitly designed to help households manage climate risk, there are good reasons to expect that cash transfers can help build household resilience against climatic risk. This study aims to provide an empirical analysis of the effect of weather risk on the welfare of rural households using impact evaluation data from the Zambia Child Grant Programme (CGP), together with a set of novel weather variation indicators.
