The number of countries falling into critical food insecurity could almost triple to 24 if global temperatures increase by 2C, research has shown.
Analysis by the International Institute for Environment and Development (IIED) shows the climate crisis will disproportionately affect food systems in poorer nations, widening the gap between the most and least vulnerable countries.
Although global heating will increase the risk of food insecurity worldwide, food systems in low-income countries are projected to deteriorate seven times as fast as those in wealthy nations.
Ritu Bharadwaj, a researcher for the IIED and author of the study, said: Countries already facing poverty, fragility and limited safety nets are projected to see the fastest deterioration in food systems, despite having contributed the least to global emissions.
