Water Poverty Index (WPI) is a simple, open and transparent tool, one that will appeal the politicians and decision makers, and at the same time empower poor people to better participate in water sector interventions and budgets development in general. The advantage of this index is that it encapsulates more than one measure of influencing factors in a single number, and one line representation of the whole picture. As such, WPI aids to effective water management in the basin that requires immediate attention.
The development of WPI is to produce a holistic policy tool, drawing on both the physical and social sciences, and having application throughout the world. It is estimated that the development of such an index will enable decision makers to target crosscutting issues in an integrated way, by identifying and tracking the physical, economic and social drivers which link water and poverty.
Water problem in Nepal is an emerging issue for the Nepal Government. Nepal is a landlocked country, significantly facing challenges related to water pollution, poverty and scarcity though it is the second richest country in the World with 2.27% of world water resource. Water resource is the most important natural resource of the country Nepal. The major sources of water are snow melt from Himalayas, glaciers, rainfall and groundwater.
The Bagmati river is the principal river of the Bagmati basin which covers nearly an area of 3640 sq. km in the Kathmandu Valley. Although it is a perennial river, water availability per population is the lowest in this river basin. The catchment area of the river is 3610 sq. km which is 2.25% of total area of Nepal.
The main aim of this research project is to find out the water situation in the Study area in the Bagmati River basin through the evaluation of WPI, a tool which is widely used to assess water poverty. Water poverty is influenced by natural and anthropogenic activities.
