The number of people living in extreme poverty could rise by between 35 m and 122 m by 2030 due to climate change , according to a report from the United Nations . Ertharin Cousin, executive director of the World Food Programme, said: “Climate change is already stretching the international humanitarian system … more than 80% of the world’s hungry live in areas prone to natural disasters and environmental degradation. The 2016 State of Food and Agriculture report argues that climate change is “ a major and growing threat to global food security ” with sub - Saharan Africa particularly vulnerable . The report calls for support for the world ’s half - billion small farms , as well as for “ deep transformations in agriculture and food systems ” . It advocates the adoption of sustainable policies within the land , water , energy and forestry sectors , and the reduction of farming emissions .
