''Climate change is projected to exacerbate malnutrition'' ( ''high confidence'' ). Moderate and severe stunting in children less than five years of age was projected for 2030 across 44 countries to be an additional 570,000 cases under a prosperity and low climate change scenario (RCP2.6) to one million cases under a poverty and high climate change scenario (RCP8.5), with the highest effects in rural areas ( [[#Lloyd--2018|Lloyd, 2018]] ). Future DALYs lost due to protein-energy undernutrition and micronutrient deficiencies without climate change have been projected to increase between 2010 and 2050 by over 30 million; with climate change (RCP8.5), DALYs were projected to increase by nearly 10%, with the largest increases in Africa and Asia ( [[#Sulser--2021|Sulser et al., 2021]] ).

The projected risks of hunger and childhood underweight vary under the five SSPs, with population growth, improvement in the equality of food distribution and income-related increases in food consumption influencing future risks ( [[#Ishida--2014|Ishida et al., 2014]] ; [[#Hasegawa--2015|Hasegawa et al., 2015]] ). A review of 57 studies projecting global food security to 2050 under the SSPs concluded that global food demand was expected to increase by 35–56% between 2010 and 2050 ( [[#van%20Dijk--2021|van Dijk et al., 2021]] ). In the same review, estimates of the change in population at risk of hunger by 2050 range between −91 to +8% if climate change is not considered and between -91 to +30% if climate change is considered, with the inclusion of climate change not leading to statistically significant differences in projections ( [[#van%20Dijk--2021|van Dijk et al., 2021]] ).
