摘要

Policies in sub-Saharan Africa are constrained by a limited knowledge of climate change extremes and a focus on agricultural production rather than nutrition supply. Here we model the impacts of future extremes on national-level calorie and nutrient supply in Zambia for production and nutrition focused policy scenarios. We identify the specific cropland, yield and import increases required to achieve climate-resilient nutrition security and highlight policy options.
