Definition We define safe drinking water as:“water that is safe to drink and available in sufficient quantities for hygienic purposes.” Our working definition of basic sanitation is: “the lowest-cost option for securing sustainable access to safe, hygienic, and convenient facilities and services for excreta and sullage disposal that provide privacy and dignity while ensuring a clean and healthful living environment both at home and in the neighborhood of users.”
Definition Renewable water resources: include all surface water and groundwater resources that are renewed on a yearly basis without consideration of the capacity to harvest and use this resource. Exploitable water resources: refer to the surface water or groundwater that is available with an occurrence of 90 % of the time, are considerably less than renewable water resources, but no universal method exists to assess such exploitable water resources. Agricultural water withdrawal: refers to the quantity of water withdrawn for agricultural purposes. It includes irrigation and livestock watering. Methods for computing agricultural water withdrawal vary from country to country.
2005 Environmental Sustainability Index Yale Center for Environmental Law and Policy andColumbia University, Center for International Earth Science Information Network,in collaboration with World Economic Forum Authors of ESI stated that In many areas, decision-making has become increasingly data-driven, but the environmental domain has curiously lagged in this regard. Difficulty by widespread information gaps and uncertainties, environmental policy-making has often been based on generalized observations, best guesses, etc. Ability of nations to protect the environment 76 datasets have been integrated into 21 indicators of Environmental sustainability: Biodiversity, Land use, Water quality, Air quality, Reducing air pollution, Environmental health, etc.
