Water is an irreplaceable and difficult natural resource to manage. Sixty percent is in either polar or glacial ice or water vapour. The remaining thirty percent of fresh water is in liquid form and potentially accessible for human use and management.
Water is an essential resource for human, animal and plant health. However, natural waters can become non-renewable by human actions such as contamination, modification of land where all of the water (surface and groundwater) flows to the lowest point or disproportionate extraction.
Access to water is a basic human right and clean, inexpensive water improves both personal and social health.
Decisions about water concern many interested parties or stakeholders. Decisions about water in one area could have sweeping implications in others.
