Projected risks for malnutrition in Africa are high : 433 million people in Africa are anticipated to be undernourished by 2030  and, compared to 1961- 1990, 1.4 million additional African children will suffer from severe stunting by 2050 under 2.1℃ global warming . In Burkina Faso, the mortality burden due to low crop yields could double by 2100 with 1.5℃ of global warming . Drought risks will include crop and livestock failures . Additionally, increasing concentrations of atmospheric CO2 will affect the nutritional quality of C3 plant staples, lowering levels of protein and minerals like zinc and iron . Declining fish catches due to ocean warming, illegal fishing and poor stock management are projected to increase deficiencies of zinc, iron and vitamin A for millions of people across Mozambique, Angola and multiple west African countries .
