Water Stress Index

  • The sub-national Water Stress Index is formulated by London-based risk analytics firm Verisk Maplecroft.
  • It lists India as the 46th highest risk country in the world.
  • 11 of India’s 20 largest cities face an ‘extreme risk’ of water stress and seven are in the ‘high risk’ category.
  • According to the index, Delhi, Chennai, Bengaluru, Hyderabad, Nashik, Jaipur, Ahmedabad and Indore are among the cities facing ‘extreme risk’.
  • The index measures the water consumption rates of households, industries and farm sectors and the available resources in rivers, lakes and streams.

Indian cities are at risk

  • According to the report the average population growth rate among the 11 extreme risk cities is 49%; more than 127 million people will call them home by 2035.
  • The UN estimates that Delhi’s population will grow from 28 million people to above 43 million by 2035, a 52% rise while Chennai will grow by 47% to top 15 million over the same period.
  • The study says Chennai is the tip of the iceberg for India’s water stressed cities.
