Influence of weather shocks and coping strategies on food consumption: Evidence from rural Niger
Weather is an important determinant of household well-being in rural Sub-Saharan Africa. This paper explores the relationship between novel measures of cropping-season weather conditions and household food consumption in rural Niger, and how household coping mechanisms mediate that relationship. We employ a panel logit model to show that the normalised difference vegetation index (NDVI) and extreme heat degree day (EHDD) measures are associated with subjective self-reporting of drought in a panel dataset of 2 264 households. We then show, with a household fixed-effects panel model, that low NDVI and high EHDD measures are associated with significant decreases in household per capita food consumption. Household coping strategies, such as the disbursement of savings, temporary migration of a family member, and the adoption of heat-resistant agricultural technologies, are found to partially mitigate, but not fully alleviate, the negative effects of weather shocks on consumption. More comprehensive coping mechanisms are needed to improve household resilience to weather shocks.
期刊介绍:
The African Journal of Agricultural and Resource Economics (AfJARE)/Journal Africain d’Economie Agricole et des Ressources (JAEAR) is a publication of the African Association of Agricultural Economists (AAAE). The journal publishes original research about how African agriculture interacts with local and global economic systems and policy regimes in its impacts upon people. The scope of the journal covers the roles of markets, technology, policy, institutions and the natural environment in shaping the lives of well being of Africans engaged in agricultural activities. The journal strives to nurture and enhance the capacity of African professionals to conduct and publish scientific research and provides a venue for communicating and disseminating their findings. Multi-disciplinary, problem-oriented articles are encouraged. Submissions may deal with teaching, research extension, consulting, advising, entrepreneurship and administration. The Chief Editors and Editorial Board, under the general direction of the AAAE President, Executive Committee and Council are charged with implementing Journal policy to serve members of AAAE. The main section of the journal publishes technical research articles while a small section is devoted to publishing brief notes with important policy content and book reviews. The journal is a quarterly publication.
