This document summarizes a presentation on powering dry areas through food security under climate change. It discusses critical factors like extreme poverty, environmental degradation, and climate impacts. Key themes in Tunisia include effects of climate change on agriculture/food security as population grows. The most pressing priorities are enhancing water productivity, crop improvement, managing salinity, and integrated livestock. Achievable goals include conserving water, developing drought/salt tolerant varieties, reducing yield gaps, and regional technology sharing. Key actors are researchers, farmers, and international organizations. Overall, it stresses the need for collaborative research on scenarios to ensure food/nutrition security under challenges like resource degradation and climate change.
