Water availability and shortages for domestic uses that are often attributed to climate change are often driven by the local presence of water in the region verses the increasing demands caused by population expansion, increase in commercial and personal usage that increasingly tax the available supplies. Therefore, human interventions to enhance the natural water usage has become more important now. In order to increase the real water availability we need to eliminate the single usage of water and introduce multiple-pass usage prior to discharge of the water. This method can be applied to several types of industries such as agricultural irrigation, food processing, industrial cooling etc.
Water Crises & Our Role
As an agricultural as well as Food processing company that is located in a country where only 50% of the population have access to an improved source of water, we have always believed that we have a huge responsibility to use strategies that optimise the use of water. Agriculture is by far the largest consumer of the Earth’s available freshwater. 69% of the world’s freshwater withdrawals are committed to agriculture. The industrial sector accounts for 19% while only 12% of water withdrawals are destined for households and municipal use. It is estimated that by 2050, the global water demand of agriculture will increase by a further 19% due to irrigational needs.
Elven Agri’s Organic Farm and processing factory have put in several strategies in place that ensure multiple usage of water before discharge. This this has been done through various recycling options made available at the Farm for agricultural irrigation and at the factory during food processing.
One of the key steps taken at our Organic farm to ensure water conservation has been installation of Drip irrigation systems. It is a method of delivering water slowly, at low pressure, at or near the root zone of the landscape plant material. Drip irrigation lets us target the precise area that we want to irrigate and lets us monitor amount of water needed for each plant. Water is subject to lesser evaporation and does not get disturbed by wind conditions; overall resulting in no loss or wastage of water.
Drip irrigation slowly delivers water to plant roots keeping the root zone moist , creating a balance of water and air around roots for optimum growth. Studies show that drip irrigation can save up to 70% of applied water compared with a sprinkler system. To conserve more water, we cover drip lines and areas around plants with mulch such as dry grass clippings which helps conserve moisture by reducing evaporation.
