Three out of four jobs worldwide rely on water. As such, water shortages and lack of access may limit economic growth in the years to come, according to the World Water Development Report 2016. From its collection, through various uses, to its ultimate return to the natural environment, water is a key factor in the development of job opportunities either directly related to its management (supply, infrastructure, wastewater treatment, etc.) or in economic sectors that are heavily water-dependent such as agriculture, fishing, power, industry and health. In its analysis of the economic impact of access to water, the report cites numerous studies that show a positive correlation between investments in the water sector and economic growth. It also highlights the key role of water in the transition to a green economy.
