TS.B.3.5 The impacts of climate change on food systems affect everyone, but some groups are more vulnerable. Women, the elderly and children in low-income households, Indigenous Peoples, minority groups, small-scale producers and fishing communities and people in high-risk regions more often experience malnutrition, livelihood loss and rising costs . Increasing competition for critical resources, such as land, energy and water, can exacerbate the impacts of climate change on food security . Examples include large-scale land deals, water use, dietary patterns, energy crops and use of feed crops.
