Description
Global hunger has been increasing since 2014, putting the Sustainable Development Goal of ending hunger by 2030 at risk. Climate vulnerability is a major driver of hunger. Food security is determined by land availability, access, utilization of food preparation and diversity, and stability. This study aims to compare the impacts of different scenarios on national food security, identify key drivers of undernourishment prevalence, and identify areas at risk of future undernourishment. Results show population growth and land use change could have the greatest impact on national food security. Key drivers of undernourishment prevalence were shown to be fossil fuels, with significant challenges to mitigation and adaptation. On the global scale, Africa was expected to be most at risk of undernourishment in the future
