According to the United Nations, the overall goal is to: "Ensure availability and sustainable management of water and sanitation for all." [1] The goal has eight targets to be achieved by 2030 covering the main areas of water supply and sanitation and sustainable water resource management. Progress toward the targets will be measured by using ...
A similar definition of water security by UN-Water is: "the capacity of a population to safeguard sustainable access to adequate quantities of acceptable quality water for sustaining livelihoods, human well-being, and socio-economic development, for ensuring protection against water-borne pollution and water-related disasters, and for ...
