Water abstraction devices exist where a water wheel provides the energy to a pump so that water can be pumped with no electrical energy demand. The causes of water insecurity are physical climate variability salt water encroachment at coasts as well as human over abstraction from rivers lakes and groundwater aquifers water contamination from agriculture industrial water pollution over-abstraction from rivers lakes and aquifers and the. Therefore it is essential to understand the environmental implications of groundwater overexploitation. Water extraction is the process of taking water from any source either temporarily or permanently for flood control or to obtain water for for example irrigation. Groundwater is a highly vulnerable and important resource for both humans and the environment.

This degradation of groundwater quality may. Water abstraction is a term that is used to define the process by which water in its natural environment may be artificially removed through some sort of manmade structure or through the process of changing the flow of the water from its usual course to some other course that the people responsible for the diversion may have set. It is usually computed as the total water withdrawn by the. Abstraction for public water supply which makes up 512 of total abstraction has been relatively stable - increasing by 31 over the same 6-year period to an estimated 53 billion cubic metres in 2017 Figure 2. In 2015 the severe water crisis in São Paulo showed the imbalance in the access to water in most large cities in Brazil and changed the way water is managed in a country with over 12 of the reserves of the planet. This presentation emphasizes the hydrologic fundamentals for such understanding which involve groundwater flow system concepts factors controlling.

Irrigation is the main cause of groundwater overexploitation in agricultural areas. CGIAR A well in Tunisia. Depending on the environmental legislation in the country controls may be placed on extraction to limit the amount of water. Yaya National Water Resources Institute Kaduna INTRODUCTION In the hydrologic cycle an aquifer is a geologic body that is porous enough to store groundwater and permeable enough to permit economic withdrawal of water for diverse human uses. The Oxford Handbook of Water Politics and Policy notes that 20 of the worlds aquifers are over-exploited and the global rate of groundwater abstraction is increasing by.

The intrusion into a freshwater aquifer of low-quality surface water or groundwater because of the change in the hydraulic gradient due to groundwater abstraction is a frequent cause of quality degradation. If the amount of water taken is greater than the amount of water falling as rain it is called over-abstraction. 57B - The Causes of Water Insecurity.
