The use of dry wells was earlier banned to protect groundwater from overextraction
. But given the impending shortage, city governments have been temporarily allowed to use them as long as they secure a permit from the National Water Resources Board, Salalima added.
The illegal practice could be a problem in the future as overextraction
at quarry sites can trigger erosions or landslides.
Kinyua said the overextraction
of the tree will make the species extinct.
Other issues such as water scarcity (the drought) in California and the western U.S., overextraction
of groundwater in the Central Valley of California and the Ogallala Aquifer, saltwater intrusion, urban stormwater management and the energy water food nexus stress (no water no food, etc.).
of both groundwater and fossil fuels allows seawater to penetrate porous deltaic sediments.
Owing to the high pressure employed, overextraction
of bitter components (e.g., naringin, neohesperidin, and limonoids)  often occurs and for this reason, the pressure must be carefully controlled.
Continuation of overextraction
exceeding the safe yield may subsequently lead to progressive decline in groundwater table .
For a thorough approach, it has also been suggested that researchers administer both tests because the procedures complement each other in that parallel analysis tends to err in the direction of overextraction
and MAP tends to err in the direction of underextraction (O'Connor, 2000).
The Moroccan authorities are also working to improve groundwater governance, to avoid overextraction
. Farmers engaged in rain-fed agriculture receive support that helps them to make better use of rainfall -- such as through the introduction of climate-resilient practices like direct seeding -- resulting in higher yields than traditional practices produce during dry years.
Asked on the issue of overextraction
of scarce ground water in several pockets of the country, Bharti replied, " India gets so much of rainfall.
K1 recommends retaining all components with eigenvalues greater than 1.0 (i.e., components should account for as much variance as that in a single indicator), but this may lead to overextraction
and consequently, unreliable, noisy components, so we relied on two additional tests (Zwick and Velicer 1986; Coste et al.
