"Food inequality and climate change: compounding impacts on caloric undernutrition" by Baldos, Uris Lantz Abstract Anthropogenic climate change is expected to place additional pressure in the world’s food systems which could lead to decreased food production (Hasegawa et al., 2014), declining in agricultural productivity (Ortiz-Bobea et al., 2021) and lower consumer well-being (Baldos et al., 2019; Gurgel et al., 2021). Food security is also threatened by adverse climate impacts and past work have incorporated measures in caloric undernourishment which are generally driven by changes in average dietary energy intake (Baldos & Hertel, 2014; Hasegawa et al., 2016; Janssens et al., 2020). This work builds on this literature by explicitly examining the compounding impacts of greater food inequality and climate-driven crop yield changes on food security. Specifically, I combine the latest mean ensemble of climate change crop yield impacts produced using climate outputs from Coupled Model Intercomparison Project (CMIP6) (Jägermeyr et al., 2021) and projected changes in income inequality under different Shared Socioeconomic Pathways (SSPs) (Rao et al., 2019). In this study, changes in income inequality are assumed to directly impact changes in food inequality. I then use a partial equilibrium model of agriculture to assess the impacts of these drivers in the underlying distribution of caloric consumption within food insecure countries (Baldos & Hertel, 2013; Fuglie et al., 2022). |
