Improving water security can be achieved through increasing water supply, reducing water demand, as well as addressing water quantity and water quality issues related to broader water resource management.

When deciding upon the allocation of water to a given use, there is a need to assess not only the expected benefits, but also the costs and risks associated with restricted access to other uses
