By 2050, two-thirds of the world's population will live in cities and urban areas. Demand for water is estimated to increase by 55% , mainly from the need to develop urbanization in developing countries. Urbanization is synonymous with the need to access clean water and sanitation.

At the same time in 2050, the world will produce 60% more food. Meanwhile, global water demand for industrial activity will increase by 400%. The entire world population needs to use energy up 70%.

The process of urbanization, increasing population and increasing water demand for food, energy and industrial production are factors that cause water shortage. According to the United Nations report, people will face a shortage of water supplies by 40%. Increasing competition means that more effective management measures can ensure everyone's need for water.

"We have to manage and use water appropriately. If we use water to irrigate and treat agricultural land with less quantity, it can provide water to serve the needs of many others ," Reuters quoted. Richard Connor, lead author of the World Water Development Report, said.
