New research: The effect of reducing per capita water and energy uses on renewable water resources in the water, food and energy nexus
A significant percentage of the world’s population does not have adequate access to water, food, and energy resources (WFE). Although efforts to achieve the UN Millennium Development Goals and later the Sustainable Development Goals (SDGs) have increased access to scarce resources, still, 25.9% of the population is affected by moderate or severe food insecurity in 2019, 2.2 billion people lacked access to potable water in 2017, and 789 million people lacked electricity service in 2018. The pressure on WFE resources will increase as the world’s population grows from 7.4 billion in 2016 to 9.7 billion in 2050.
