How Climate Change Affect Food Security By Akinmade Iseoluwa Pdf Climate change and unsustainable food systems interact reciprocally with adverse impact on food and nutrition security. climate change impacts food systems via multiple pathways, including soil fertility, water availability, reduced food yield, reduced food nutrient concentration and bioavailability, increased food anti nutrient content and. In this paper we narrow our focus on the potential effects of climate change on the agrifood system from the latest intergovernmental panel on climate change (ipcc) climate projections (isimip3b cmip6) and modeled estimates of food and nutrition security that result from the complex interplay of factors and drivers across commodities, countries.

Key impacts on food security and nutrition • all dimensions of food security will be affected, but the majority of assessments are on food production availability • nutrition can be affected through changes in food intake, diseases. • ↑global food production for ↑t of moderate size, ↓production for further warming.
