The problems of overexploitation of aquifers in semi-arid areas: the Murcia Region and the Segura Basin (South-east Spain) case T. Rodr´ıguez-Estrella Technical University of Cartagena (UPCT), Department of Mining, Geological and Cartographic Engineering, Paseo Alfonso XIII, 52, 30203 Cartagena, Spain Aquifer origin volume is indicated with links emanating from the outer bar of the same color. Email. The common argument against the utilisation of SPIS is that this technology goes hand in hand with overexploitation and eventually depletion of limited water resources such as groundwater. Myint Thein, Consultant (Groundwater & Wells) Advisory Group Member (Groundwater) NWRC, Myanmar. Current status of Groundwater in greater Yangon compare to Bangkok: Bangkok is more 40 years advance in groundwater management than Yangon. This requirement is mostly met through groundwater, extracted from the shallow aquifers of the WR-2 watershed. Facebook Count. Twitter Share . Overexploitation of groundwater in India is reported to be so acute in several regions of India subsequent to the depletion of ground water table in an alarming rate. Pumping water out of the ground faster than it is replenished over the long-term has caused similar problems.
Several cities, such as Mexico City, Aguascalientes, Morelia, and Querétaro, use groundwater as the primary source of water supply and contributes >70% to the water needs of >100 million inhabitants (Conagua, 2003; INEGI, 2011). Water extraction drops the level of fresh groundwater, reducing its water pressure and allowing saltwater to flow further inland. Groundwater pumping from coastal freshwater wells, have increased saltwater intrusion in many coastal areas. Some of the negative effects of sustained groundwater pumping are: drying up of wells; reduction of water in streams and lakes Over-exploitation of groundwater resources and their environmental and socio-economic implications: the case of Jordan. (2008). Groundwater is a highly vulnerable and important resource for both humans and the environment; therefore, it is essential to understand the environmental implications of groundwater overexploitation. 1, pp. groundwater seem to be the solution. Essay on Overexploitation of Groundwater (with statistics) Article Shared by. International virtual groundwater transfers from overexploited aquifers in the United States. Over-exploitation of groundwater (GW) in the North China Plain (NCP) since the 1960s has many environmental consequences. Persistent groundwater overexploitation in the northern parts of the NCP has resulted in water-level declines in both shallow and deep aquifers. Water tables beneath Beijing have been dropping 1-2 metres a year and a third of its wells have reportedly gone dry. 33, No. Water International: Vol. (2008). Water International: Vol. Overuse of groundwater is now ubiquitous in parts of China, India, Mexico, Thailand, the western USA, north Africa and the Middle East. This email address is being protected from spambots. The volume of groundwater in storage is decreasing in many areas of the world in response to excessive pumping. 55-68. ADVERTISEMENTS: Water crisis has been caused due to growing population and increase in demand of food-grains and also subsequent Green Revolution in the late sixties. ion of groundwater resources in the coastal aquifer system of Argolis is investigated since the late 1950’s. The size of the outer bar indicates the total virtual groundwater export volume for the ME aquifer (blue), HP aquifer (yellow), and CV aquifer (green). Over-exploitation of groundwater.
The watershed area incorporates a rich orange orchard belt that requires a huge quantity of water for irrigation. 33, No. Such overexploitation can be allowed, taking into account various factors such as the development of the community, environmental impact, needs of future generations, etc. 1, pp. Aquifer overexploitation has caused a significant decline of the piezometric head up to 100 m in these sites. The WR-2 watershed is located in the Deccan trap basaltic terrain of Maharashtra State, India. Many of the most important water projects in these regions focus on fossil water creating a sort of “pumping race” between the countries that share common aquifers, where overexploitation of groundwater in these regions is the major cause of seawater intrusion problems [34,35,38–46].
