Intense need of groundwater recharge…..
Water THAT is found underground in cracks and spaces in soil, sand and rocks is considered as groundwater which is stored in aquifer and moves via geologic formations of soil, sand and rocks. These aquifer is in permanent motion from areas of natural and artificial recharge to natural and artificial drainage outlets. It is an obvious thing that human beings are dependent on groundwater, as groundwater supplies drinking water to large number population and moreover groundwater is the main source of recharge for lakes, rivers and wetlands. The 70 percent of the precipitation on land is lost and remaining 25 percent penetrates downward to the aquifers and moves as groundwater from recharge areas to natural discharge outlets on the surface of the ground as springs, streams, lakes and oceans. It’s very sad to say that in Pakistan underground water reserves are under threat. Groundwater situation in Pakistan is getting from bad to worst. The dependence of household, industry and agriculture on groundwater is increasing day by day that causing groundwater economy under critical stress. Associated with massive pumping of groundwater aquifers through legal or ill-legal, unrestricted expansion of tube-wells. The groundwater exploitation creating severe negative impacts on environment and economy. It also causing serious threats to the sustainability of irrigated agriculture in the country. In 2008, freshwater withdrawals for Pakistan was 183.5 billion cubic meters, growing at an average annual rate of 6.22 percent. Out of this 93.95 percent of total withdrawal is consumed for agriculture purpose. The enormous increase in the groundwater withdrawal during the last half-century carried out by thousands of farmers is due to alternate for consistent irrigation water supply. Two decades back in Pakistan the number of tube wells installed were 659,278 and in 2012-13 their number had risen up to 1,175,073. The groundwater in Indus Basin aquifer is expiring on a very fast pace. Pakistan is already categories as water-stressed country by world Bank and the Asian Development Bank and likely to face acute short fall over the next five years. It is pertinent to mention that Indus Basin is among 21 of the world’s 37 largest aquifers which have losing it sustainability tipping points means more water has been consumed than replaced. As per Punjab irrigation department, water table in Punjab is declining by three feet per year. The groundwater table will come under severe pressure with this continues trend. To overcome this situation, war like efforts are being made across the globe. Storage dams are planned for time of access water. This can be done through injection wells after every rain fall for groundwater recharge purpose. These wells help to place surface water into groundwater storages to avoid evaporation losses. These wells can be useful to control saline water upcoming in the coastal aquifers. Keeping in view the utmost need of groundwater and its sustainable use it is necessary to develop groundwater regulatory framework to control and optimize groundwater regulation. Water is not something which have any alternate, we can’t ignore it’s sensitivity, not only to be stressed but to be resolved as well, as soon as possible. If we keep ignoring this sensitive issue, then the predictions of dry Pakistan in 2025 couldn’t be made false. There is need of time to promote groundwater recharge along with proper set of rules and laws for the use and access of groundwater which is under no legal discipline.https://www.technologytimes.pk/intense-need-of-groundwater-recharge/Editorialgroundwater,intense,RechargeWater THAT is found underground in cracks and spaces in soil, sand and rocks is considered as groundwater which is stored in aquifer and moves via geologic formations of soil, sand and rocks.
