are estimated to increase nutrition-related diseases and the number of undernourished people by 2050, affecting tens  to hundreds of millions of people , particularly among low-income households in low- and middle-income countries in sub- Saharan Africa, South Asia and Central America , for example, between 8 million under SSP1-6.0 to up to 80 million people under SSP3-6.0. At 3ºC or higher global warming levels, adverse impacts on all food sectors will become prevalent, further stressing food availability , agricultural labour productivity and food access . Regional disparity in risks to food security will grow at these higher warming levels, increasing poverty traps, particularly in regions characterised by a high level of human vulnerability .
