Water scarcity could affect 5 billion people by 2050
A new report claims that half of the world’s population may struggle to quench its thirst in the coming decades.
The news: UNESCO’s new World Water Development Report says that 3.6 billion people currently live in places that can suffer from water scarcity for at least one month of the year. It projects that the figure will rise to five billion—half of the world’s predicted 10 billion population—by 2050.
The solution: Might not be entirely technologocial. While innovations in things like irrigation and desalination will help deliver water to some people, UNESCO argues that natural methods that trap water in soils could help protect 1.7 billion people from water scarcity.
