First, what is the right path to sustainability? Mishra proposes the decentralisation of groundwater recharge. Photo by Hamish John Appleby. The Sonoma County Water Agency manages surface flow in both of those streams via its control of upstream reservoirs.
Unlike rivers or lakes, recharge of groundwater can take years. Up to 80 percent of the population relies on groundwater for both drinking and irrigation. Despite receiving one percent higher than normal rainfall between andnorthern India experienced severe groundwater depletion primarily due to widespread overextraction for irrigation of crops like rice and wheat.

Groundwater rejuvenation in parts of India influenced by water-policy change implementation. Other groundwater basins in Napa and Sonoma counties are already subject to these requirements.
A study found that groundwater management strategies likely contributed to a marked reversal from decreasing groundwater storage during to in Gujarat and Andhra Pradesh to replenishment from to At its core, the process involves creating a new government agency to regulate groundwater.
He suspects the change in priority is a result of connections between groundwater and surface water. Northern India, region 7, has undergone severe groundwater depletion mainly due to agricultural irrigation.

They noted a long-term decline in rainfall over parts of northern India since the s such as in the Gangetic Plains, resulting in more frequent droughts. Relative contribution of monsoon precipitation and pumping to changes in groundwater storage in India. The expenses are numerous. In addition, consultants must be hired to study the hydrology of the basin and, in many cases, to conduct a rate study to figure out how much each groundwater user should pay into the program.
Global trends in land freshwater availability as shown by Terrestrial Water Storage, TWS — the sum of groundwater, soil moisture, surface waters, snow and ice in centimetres per year. The Healdsburg groundwater basin, for instance, is connected to surface flow in the Russian River.
Eastern India, region 13, has seen freshwater decline due to groundwater depletion for irrigation and lower monsoonal rainfall. Second, who should pay for groundwater management?
Limiting subsidised electricity Shah and Mishra state that subsidised electricity provided by state governments is largely to blame for the over-extraction as farmers use it extensively to run pumps that draw up groundwater.
Sasaki said the entire population benefits from sustainable aquifers and their connection to surface-water flows.
The cause of the trend in each outlined study region is briefly explained and colour-coded by category. The basins shown in gray on the map are already subject to law.i.
Management of aquifer recharge and discharge processes and aquifer storage equilibrium GEF-FAO Groundwater Governance Thematic Paper 4: Authors: Peter Dillon*, Enrique Fernandez Escalante **. Groundwater in northern and eastern India is undergoing severe depletion as measured by satellite data between andmainly due to intense extraction for crop irrigation.

The depletion of California's aquifers by overpumping of groundwater has led to growing interest in "managed aquifer recharge," which replenishes depleted aquifers using available surface waters, such as high flows in rivers, runoff from winter storms, or recycled waste water.
