TS.C.6.4 Climate impacts on food systems are projected to increase undernutrition and diet-related mortality and risks globally . Reduced marine and freshwater fisheries catch potential is projected to increase malnutrition in East, West and Central Africa  and in subsistencedependent communities across North America . By 2050, disability-adjusted life years due to undernutrition and micronutrient deficiencies are projected to increase by 10% under RCP8.5 . These projected changes will increase diet-related risk factors and related non-communicable diseases globally and increase undernutrition, stunting and related childhood mortality, particularly in Africa and Asia . Near-term projections  of undernutrition are the highest for children , which can have lifelong adverse consequences for physiological and neurological development as well as for earnings capacity. Climate change is projected to put 8 million  to 80 million people  at risk of hunger in mid-century, concentrated in sub-Saharan Africa, South Asia and Central America . These climate change impacts on nutrition could undermine progress towards the eradication of child undemutrition .
