<div> <p>This dissertation examines long-run food security in Niger in an era of climate change and comprises three interlinked essays. The first essay investigates the socio-economic projections for Niger in the current climate change literature in a growth accounting framework and provides a critical assessment to evaluate global projections in the context of a low-income developing country. The second essay quantifies the combined and individual impacts of income, population growth, agricultural productivity, and climate change on food security outcomes by mid-century in rural and urban Niger. Finally, the third essay assesses three policy scenarios considering accelerated investments in agricultural research and dissemination (R&D), reductions in fertility rates, and regional market integration.</p> </div> <br>
