Lessons Learned and Way Forward

Abstract

Over the past century unprecedented developments like growing population, urbanisation and industrialisation have resulted in shrinking freshwater supplies. The current signs indicate that the situation on the ground is getting worse, and not better. Thus, the water managers, planners and policy makers around the world face the challenge of finding new sources of supply to address perceived new demands. The challenge is more acute because the options for increasing the supplies have become expensive and are often environmentally damaging.
