Population could outpace water by mid-century: Technological advances needed in coming decades to avoid water shortages

Population growth could cause global demand for water to outpace supply by mid-century if current levels of consumption continue. But it wouldn’t be the first time this has happened, a Duke University study finds.

Using a delayed-feedback mathematical model that analyzes historic data to help project future trends, the researchers identified a regularly recurring pattern of global water use in recent centuries. Periods of increased demand for water — often coinciding with population growth or other major demographic and social changes — were followed by periods of rapid innovation of new water technologies that helped end or ease any shortages.
