  • World Bank report suggests “New Water-Food Nexus Framework” for smarter hydrological use to feed 10 billion people

    Why in the News?

    In March 2026, the World Bank released a landmark report titled “New Water-Food Nexus Framework” ahead of World Water Day. The report warns of a “Global Water Bankruptcy,” stating that current water management can sustainably support food for only 3.4 billion people, far short of the 10 billion projected by 2050.

    Economic Impact of Productivity:

    • A 10% increase in agricultural productivity can lead to a 2.5–3% reduction in poverty.
    • Expanding irrigation in rainfed areas could potentially create 245 million jobs globally.

    Global Water Bankruptcy:

    • The UN and World Bank warn that water crises are no longer “temporary” but a structural state of bankruptcy.
    • South Asia (including India) is flagged for overexploiting resources, while Sub-Saharan Africa is noted for underusing available water.

    The “New Water-Food Nexus Framework”: 

    • The report categorizes nations into four quadrants to guide policy:
      • Water-secure food exporter: Abundant water, exports calories (e.g., Brazil).
      • Water-secure food importer: Has water but relies on trade for food.
      • Water-stressed food exporter: High water risk but remains a major exporter (India falls here).
      • Water-stressed food importer: Lacks water and relies on imports (e.g., Middle East).
    [2023] Consider the following statements: 
    Statement-I: According to the United Nations’ ‘World Water Development Report, 2022’, India extracts more than a quarter of world’s groundwater withdrawal each year.

    Which one of the following is correct in respect of the above statements? 
    (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I (c) Statement-I is correct but Statement-II is incorrect (d) Statement-I is incorrect but Statement-II is correct
