Résumé / Abstract

The contribution of population growth in water demand projections is often obscured, since only the increase in domestic water demand is usually taken as an indication of the increase in water demand due to population growth. This paper aims to quantify direct (domestic) and indirect water requirements (e.g. for food production, energy etc.) to sustain an individual at a particular lifestyle level. The average domestic water demand projected to the year 2015 accounts for only about 20% of the average full demand while the water demand for the production of food and consumer goods and for employment accounts for 80% of the full water demand to sustain an individual. The full water demand of the 1995 increase in the South African population of about I million people, projected to the year 2015 when the newborns reach adulthood, is conservatively estimated at 638 MUd or about 23% of the current average daily water supply of Rand Water, indicating the tremendous pressure on water resources as a direct consequence of the high current levels of population growth.
