How will global access to food, water, and energy evolve in coming decades' A new study co-authored by MIT researchers suggests the answers could be very different depending on region, resource, and income. Based on extensive modeling of many different resource scenarios, the study finds that in some regions, lower-income people could be spending roughly 50 percent of their income on food by the year 2050, in contrast to higher-income groups that could spent about 5 percent of income on food in the same areas. 'For a lot of these outcomes, the lower-income groups see much worse potential insecurity,' says Jennifer Morris, a principal research scientist at the MIT Center for Sustainability Science and Strategy and the MIT Energy Initiative, and co-author of a new paper detailing the findings. The results, she notes, can be evaluated by policymakers in different global regions to understand what the long-term, large-scale resource security risks may become for different parts of their...
