WATER SAVINGS STRATEGIES: FARMS
Farms account for 70% of the water consumed and most of this water is wasted, due to their irrigation systems. Farmers are using large amounts of water for agriculture and due to the little income and severe problems they face it is hard for them to cut down on water usage because the water is necessary for the growth of crops and the crops to keep them alive.
Yet there are useful strategies for saving, conserving and keeping clean water which farmers could use:
1. Efficient Irrigation systems
Irrigation is the application of water to the soil, sprinklers are an example of a common irrigation system.
Some Irrigation problems are waterlogging and drainage problems, due to the large amount of water being applied to the soil, the drainage systems in rural areas often have problems and waste alot of water.
2. Water Pollution
Water pollution is one of the key problems that make water unsafe to drink yet farmers usually pollute and infect their water because of the chemicals and pesticides which are used on the crops these chemicals later pollute rivers and lakes and make the water unsafe to drink. Farmers can be more careful and apply chemicals and pesticides only when absolutely needed, they should also apply a good quality and water safe type of pesticide so that after it is used it does not pollute the water.
