Human demands on the world’s available water supplies continue to grow due to rapid population growth, urbanization and industrialization. In the endeavour to manage water to meet human needs, greater demand for increasing smaller supply of water resources in the country and the ecological consequences have been tragic. If we hope to sustain water biodiversity, the appropriation of water flows must be better managed in order to ensure a wealth of goods and services for society in healthy water ecosystems.
To protect the ecological integrity of affected ecosystems, ecologically sustainable water management must occur in order to meet intergenerational human needs. Ecological integrity is protected when the compositional and structural diversity and natural functioning of affected ecosystems is maintained.
