Agriculture’s Thirst
Agriculture accounts for 72% of all freshwater withdrawals globally. Some 25% of the world’s population depends on groundwater that is being pumped faster than nature can replenish it. Across the planet, 66 countries allocate more than 75% of their water to agriculture, leaving little margin for drought, population growth, or ecosystem needs.
Day Zero
Day Zero—the moment a major city’s taps run dry—could emerge as early as
2030. By 2050 an additional 1 billion people will face extreme water stress, and 100% of the MENA region’s population will live under extreme stress. The annual financing gap to avert this crisis stands at $140.8 billion.
