The Gambia faces numerous food system challenges, including growing food demand, climate change, land degradation, low agricultural productivity, and a high dependence on food imports that are at risk from external shocks. To address these challenges, there is a need to increase domestic food production while limiting deforestation. In this study, we used the FABLE Calculator, a food and land-use system model, to simulate scenarios for future food demand and increasing domestic food production. We considered the impacts of climate change on crops, the implementation of climate change adaptation techniques, as well as the potential of enhanced fertilisation and irrigation to boost crop productivity, and assessed whether these measures would be sufficient to meet the projected increase in food demand.
