CLIMATE CHANGE MITIGATION EFFECTS ON HUMAN HEALTH THROUGH UNDERNOURISHMENT

Abstract

 In this study, we clarified the health damage caused by climate change mitigation throughout undernourishment using multiple global agriculture economic models. As a result, the ambitious climate policy, if it is not properly implemented, would negatively affect human health. In the scenario equivalent to the 2 °C target agreed in the Paris Agreement, in 2050 DALY attributable to childhood underweight is expected to increase by 1.7 million years (0.16 to 2.75 million years), and the economic value of life lost is expected to increase by $4.4 to 200 billion (equivalent to 0.032-1.5% of global GDP in 2050), compared to the scenario without climate change and without climate change measures. This result suggests necessity of implementing complementary measures such as food support to the poor along with climate change mitigation.
