Water security is a major challenge for many countries, especially developing ones. The numbers tell a story of water resources under stress while competition for their use is increasing – by 2025, about 1.8 billion people will be living in regions or countries with absolute water scarcity. Clean water and adequate sanitation is still far from reach for many of the world’s poorest. At the same time, more water is needed to produce food and energy to satisfy the rising needs of the earth’s growing population.
Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants.
For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 decades, then the rate at which pollutants have accumulated in shallow aquifers can only have equaled or exceeded that rate.
The lack of care given to groundwater is placing a huge tax on the poor who have no access to clean piped water supply and depend on groundwater for their health and livelihoods. Self-supply, through the use of wells, from polluted aquifers in urban and rural areas is widespread, but un-reported. The impacts are all too apparent in the densely populated urban slums and rural communities that often live just centimeters above polluted soil and rock. Out-migration of poor farmers who are no longer able to access deepening groundwater tables has been a feature in arid and semi-arid regions, but intensive agriculture is also leaving behind a legacy of nitrates and pesticides which imprint aquifers for decades.

China’s most arid regions are facing an increasingly serious water crisis, and local water policies often aggravate the problem. In such climates, growth in the agricultural sector has come with high environmental costs.
With the help of new technologies that measure real water consumption in agriculture, governments are designing innovative water rights systems that actually save water. Based on results from two successful pilots, the World Bank Group is partnering with China to tap into science to transform water management in agriculture at the national level.
