Groundwater is an important water resource for the supply of drinking water, especially in arid countries. The Arab region is one of the most water-scarce in the world and groundwater is the most relied-upon water source in at least 11 of the 22 Arab states. Over-extraction of groundwater in many parts of the region has led to groundwater table ...
Graphic on Groundwater Flow. Groundwater-Dependent Ecosystems (or GDEs) are ecosystems that rely upon groundwater for their continued existence. Groundwater is water that has seeped down beneath Earth's surface and has come to reside within the pore spaces in soil and fractures in rock, this process can create water tables and aquifers, which are large storehouses for groundwater.
One of the sources of groundwater contamination can be linked to animal agriculture and Animal feed operations (AFO). These facilities tend to have a higher concentration of animal manure , which when stored improperly can cause problems by leaking into local groundwater and aquifers, causing groundwater contamination.
Subterranean fauna is found worldwide and includes representatives of many animal groups, mostly arthropods and other invertebrates.However, there is a number of vertebrates (such as cavefishes and cave salamanders), although they are less common.
Across the world there’s a rapid depletion in the underground reserves of water that billions of people rely on for drinking, irrigation and other uses, new research has found.
Eventually, extracting groundwater may become so difficult that farmers may be forced to abandon irrigated agriculture. Some notable examples include: The hundreds of tube wells installed in Uttar Pradesh , India, with World Bank funding, have operating periods of 1.4 to 4.7 hours/day.
