Population growth, industrialization, urbanization, agricultural
intensification, and water-intensive lifestyles are placing greater

Over the past century world water withdrawals increased almost
twice as fast as population growth.
Growth of population occurs mainly in developing countries, with
developed countries populace remaining fairly stable.
