Highest Usage Of Freshwater By Country

Some of the world's most populous countries and largest economies inherently use some of the largest quantities of water.

Some of the world’s most populous countries and largest economies also use the largest quantities of water, as doing so is necessary to meet the municipal, commercial, industrial, and agricultural needs of their people and economies. Water consumption has been on the increase in the recent decades, and an increase in global population is a major contributor to this increasing water consumption. Demand for the resource is estimated to increase by 64 Billion cubic meters annually. The countries which use the highest volumes of freshwater are briefly discussed and analyzed below.

India

India uses 7610.0 billion cubic meters of water annually. India gets its surface water from rivers such as the Ogallala Aquifer, and the Mahomet Aquifer. Some of these water resources are increasingly threatened by depletion. The Ogallala Aquifer has been subjected to large volumes of agricultural and municipal withdrawals while it is inadequately replenished. The water sector in the US produces high-quality water regarding citizens’ health and the environment. However, the water system is not exactly error free due to cases of industrial pollution. Notable lawsuits have been filed by the residents of Chicago and Flint, Michigan, over what they termed as contaminated tap water that endangered their health.

Pakistan

Pakistan uses 183.5 Billion cubic meters annually. Groundwater is the primary source of Pakistan’s water followed by surface water. Most of the water is utilized in the agricultural sector through irrigation as Pakistan is a major agriculture economy. Other areas that use the resource are industrial, domestic, and power generation. The Pakistan government has undertaken significant strides to improve water accessibility and safety. The steps taken are however not adequately funded, and safe water in Pakistan is major problem. Unsafe water leaves Pakistan’s population vulnerable to water- borne diseases. Waste water treatment in Pakistan is largely inadequate, and this leads to the contamination of water sources. Increasing aggressive irrigation in Pakistan has exposed some aquifers to depletion such as the Kuchlagh Basin. Changing climatic conditions have caused reduced rainfall such that aquifers are not adequately replenished. Depletion of groundwater is a looming crisis in Pakistan.

Concerns Over Depletion

Other high water consuming countries are Indonesia, which uses 113.3 billion cubic meters of freshwater per year, followed by Iran (93.3 billion), Vietnam (82.0 billion), Philippines (81.6 billion), Japan (81.5 billion), and Mexico (80.3 billion). Notably, emerging economies have a high water consumption rate. These countries use water to drive their economies especially in the industrial sector and power generation. Environmentalists are increasingly concerned if economic development in some of these countries is sustainable owing to the continued depletion of natural water sources.
