Reform economics for managing global water supply

In their call for protection of the global water cycle, Johan Rockström and his colleagues propose putting an economic value on ‘green’ water, which is held in the air, biomass and soils (Nature 615, 794–797; 2023). In my view, it’s even more urgent to fix the underpricing of ‘blue’ water in rivers, lakes, reservoirs and aquifers if we are to reduce the risk of water-scarcity crises.
