31 January, 2019

The guidelines intend to assist countries in the assessment on water stress by contributing data on environmental flows (EF) which are necessary for the calculation of SDG 6.4.2, indicator on water stress. Assessing environmental flows improves water management by ensuring a sustainable water supply that meets the needs of people, agriculture, energy, industry and the environment within the limits of availability.
