Water, as the source of all life, is the most precious substance on the planet. Its comparative abundance has led to many misuses which will seriously impair our common future. Problems such as water degradation and contamination are impossible to resolve without the participation of many different disciplines. These issues are, by definition, trans-national and relate to rights of states and hence it is essential to discuss these at international level to arrive at equitable and binding solutions that will ensure the rights of society to quality water supplies.
