Meeting the urban challenge

World Water Day has been celebrated worldwide on March 22, since 1993 to highlight the importance of freshwater and the need to manage it sustain-ably. The theme of World Water Day 2011 is ‘Water for cities: responding to the urban challenge’. It aims to focus international attention on the impact of rapid urban population growth, industrialization, and the uncertainties caused by climate change, conflict, and natural disasters on urban water systems.

The amount of water available per person in cities is decreasing rapidly, putting pressure on available water resources, both in terms of quality and quantity. Theoretically, there is plenty of water available in Nepal, but there are large variations on when and where the snow and rain falls. At any given time, there is either too much or too little water. People are faced with both acute shortages and floods.
