The impact of weather shocks on food security in Uganda: a panel regression analysis
Climate change endangers food security globally and in Uganda particularly. Our objective was the assessment of weather shocks’ impact on the food security of smallholder households in Uganda. We used the Uganda National Panel Survey (UNPS) data. A multistage cluster sampling procedure had been employed to recruit respondents. We used the periods 2013/2014, 2015/2016 and 2019/2020 to construct an unbalanced panel with 3,935 observations. We employed Poisson and logit fixed effects panel regressions. Food security was measured as the number of meals consumed by a farming household each day or alternatively the likelihood of experiencing a food shortage. Our main result is that weather shocks unequivocally reduce households’ food security. Furthermore, households that are large, female-headed, lack literacy or assets or reside in Northern Uganda or in rural areas tend to suffer from reduced food security. In contrast, non-agricultural (business) activities improve the food security of households. Households with low asset ownership or residing in the North are hit hardest by weather shocks in terms of the number of meals, while households with middle asset ownership are hit hardest regarding food shortages. For development policy, our results are in favour of region-specific support for climate adaptation and for non-agricultural (business) activities, the improvement of literacy via better education and support for building up assets or starting non-agricultural (business) activities.
期刊介绍:
Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches.
Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet.
From this perspective, the journal covers the following areas:
Global food needs: the mismatch between population and the ability to provide adequate nutrition
Global food potential and global food production
Natural constraints to satisfying global food needs:
§ Climate, climate variability, and climate change
§ Desertification and flooding
§ Natural disasters
§ Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production
§ Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production
The sociological contexts of food production, access, quality, and consumption.
Nutrition, food quality and food safety.
Socio-political factors that impinge on the ability to satisfy global food needs:
§ Land, agricultural and food policy
§ International relations and trade
§ Access to food
§ Financial policy
§ Wars and ethnic unrest
Research policies and priorities to ensure food security in its various dimensions.
