Global Water Stress and Management

Rutger Hofstra from the World Resources Institute discusses water stress, defined as the ratio of water demand to supply. He highlights that 61 countries face high water stress, driven mainly by increased demand. The report suggests that proper management can mitigate water stress, with examples from countries like Namibia and Australia. Recommendations include improving agricultural efficiency, using green and gray infrastructure, and recycling wastewater. While individual consumption is not the focus, the discussion emphasizes global trends and solutions.
