Abstract [en]

Shortage of water has been recognised as an important obstacle to development of various sectors of socity, primarily food production, and, to a lesser extent, industrial expansion. Lack of access to safe water for household use is also a significant drawback for human well-being. As a consequence, the effort to withdraw water from streams, lakes and from the ground, has been substantial during recent decades. From a supply augmentation point of view, the past focus on the quantitative aspects of water provision to sectors in society has, no doubt, been successful. The prevailing policy has, however, evolved with scant attention to the threat to water quality degradation which is an inevitable by-product of an intensified water resources utilisation. This is particularly apparent in dry areas where the dilution effect of natural water courses is reduced as a result of increased withdrawals. Another shortcoming of the water supply policy has been a surprising lack of concern about how water is actually being used in various sectors, what relative benefits are generated, and how water is being disposed after use. It is argued in this article that high rates of water withdrawal necessitate a change in water policy. Among other things the connections between water quantity and quality will have to be dealt with and also the allocation of water supply between incompatible and competing water uses.
