Climate Change and Water Poverty: The Indian Scenario

Jagriti Kher, Savita Aggarwal and Geeta Punhani

Abstract

Climate change has become a reality, observational records and climate projections provide evidence that fresh water resources are most vulnerable. While on one hand, demand for water is increasing rapidly, on the other hand the availability of water faces serious threat from human induced climate change making it important to monitor the management of water across different regions. A water management tool, known as the Water Poverty Index (WPI), later modified to Climate Vulnerability Index (CVI) has been developed by Sullivan et.al.in 2002 and 2009 respectively encompassing various components such as water resources, access to water and it’s use, human capacity to lobby for water, the state of environment and the geospatial characteristics which includes climate. The present study was undertaken to quantify the climate vulnerability index for water at the household level (CVI-WH) for states and UTs in India. The study has shown that the states of Jharkhand, Bihar and Madhya Pradesh were the most vulnerable to climate and water related stresses with CVI-WH values greater than 0.61. Conversely, Goa and Chandigarh were the least vulnerable with low CVI-WH values of 0.36 and 0.37. Thus CVI-WH can be used as a tool to monitor the water stress at the regional level to determine priority needs for intervention in water sector
