Water Waste in Agriculture

Chris Chen
Currently, about two-thirds of water we employ in our daily lives is going to waste. However, efficient water usage technologies could reduce waste to about 15%. If we invest in efficient water technologies, it would reduce the burden on wastewater plants and transfer projects that irreversibly alter habitats for both people and wildlife. It will also allow the aquifers deep in the ground to recharge and conserve money and energy that must be used to extract the deep groundwater.
Many experts believe that the reason so much water is wasted is because it is undervalued. This is due to government subsidies that increase the supply of water and drive prices down. Since the price is so low, it gives people very little incentive to conserve it. The problem with making the unpopular political decision to raise prices is that low-income farmers and city dwellers will find it increasingly more difficult to buy enough water to satisfy their needs. On the flip side of the issue, proponents of water subsidies argue that it promotes settlement and agricultural production in arid areas, stimulate economies, and lower the price of food and other goods and services for consumers. This is because a low priced factor of production will allow businesses to keep the prices on their products low.
Another reason that experts believe is at the center of the problem known as water waste is the lack of subsidies for technologies that improve the efficiency of water use. If more subsidies for such technologies existed, businesses would have an incentive to invest in better systems and conserve the precious water.
Since most of the water consumed on earth is used in irrigation and agriculture, it makes the most sense that it should be the first to see reform. It is estimated that about 40% of water used in agriculture actually reach crops and contribute to food production. A method that performs extremely poorly is the flood irrigation. It often delivers more water than plants actually require and only 60% of the water is absorbed and made useful. An alternative to this method is to use a center-pivot low-pressure sprinkler that boasts 20% losses and allows water use to be slashed to a fourth of the current amount.
