WWF identifies 100 cities, including 30 in India, facing ‘severe water risk’ by 2050:


Context:

A hundred cities worldwide, including 30 in India, face the risk of ‘severe water scarcity’ by 2050, according to a recent report by the World Wide Fund for Nature (WWF).

The cities include:

  • Global hubs such as: Beijing, Jakarta, Johannesburg, Istanbul, Hong Kong, Mecca and Rio de Janeiro.
  • Indian Cities such as: Jaipur, Indore, Thane, Srinagar, Rajkot, Bengaluru etc.

More than half of the identified cities are from China and India.

What’s the concern and challenge?

The cities would face a ‘grave water risk’ by 2050 due to a dramatic increase in their population percentage to 51 per cent by 2050, from 17 per cent in 2020.

What needs to be done?

  1. Cities need to invest more in nature-based solutions and enhance the health of river basins, watersheds and wetlands to build resilience to water risks.
  2. To manage these initiatives, a public funding pool needed to be created in collaboration with the private sector to invest, reduce risk and generate returns and fuel sustainable economic growth.
  3. Cities also needed to support greater global efforts to mitigate greenhouse gas emissions to avoid reaching these scenarios.
