Geographic Disparities in Future Global Food Security : Exploring the Impacts of Population Development and Climate Change
Meeting the food demands of a growing population is one of the currently most critical issues for the world community. Additionally, negative impacts of climate change on agriculture are expected in some densely populated regions of developing economies. In this thesis, I examine spatial patterns of...

Meeting the food demands of a growing population is one of the currently most critical issues for the world community. Additionally, negative impacts of climate change on agriculture are expected in some densely populated regions of developing economies. In this thesis, I examine spatial patterns of future impacts of population development and climate change on food security and how these impacts correlate with current patterns of food security and poverty. I aim to assess the global spatial patterns of food insecurity, concerning the current situation and future prognosis, to quantify the impact of population development and climate change on food security, and to examine to what extent poverty can explain spatial patterns. To identify spatial patterns, I performed a multiple correlation analysis. The aggregated impact estimate of population development and climate change was calculated by adding their respective national predictions. The explanatory power of poverty was evaluated using regression models which contained population development predictions and current food security as functions of poverty rate. Based on the my results and a literature review I discuss the future geographic disparities of food security and the corresponding consequences for combating hunger. My results show that global geographic disparities are likely to increase substantially, mainly because population, and in turn food demand, will increase strongly in sub-Saharan Africa, the region with the highest decline of resources in relation to population. Impacts of climate change show a similar geographic pattern where foodinsecure regions will be affected the most.
