Abstract
Climate change is expected to have far-reaching impacts on food security. Such impacts are likely to be higher in developing countries. This paper analyses the state of research on the nexus between climate change and food security in Burkina Faso. In particular, it sheds light on whether and how the scholarly literature addresses the impacts of climate change on the four dimensions of food security (i.e. food availability, food access, food utilisation and stability). It also explores the synergies and trade-offs between climate change mitigation/adaptation and food security. A search performed in April 2020 on the Web of Science yielded 243 records and 62 of them, which resulted eligible, were included in the systematic review. The literature shows that climate change will affect all the four dimensions of food security. However, most of the analysed literature addresses its effects on food availability. Indeed, it focuses on impacts on crop yields and climate suitability for crops (e.g. maize, millet, sorghum). Moreover, most of the impacts on the remaining food security dimensions stem from the negative effects on food production and supply (cf. food availability). The review also shows that, on the one hand, climate change mitigation can undermine food security and, on the other hand, agriculture intensification and some adaptation strategies, which aim to enhance food security, might increase emissions from agriculture. The dual climate change-food security relationship calls for integrated policies that address trade-offs and optimise co-benefits between 'climate action' and 'zero hunger' in Burkina Faso.
