GS–3 | WATER RESOURCES & CLIMATE CHANGE

3. Day Zero

Subtopic: Urban Water Security, Climate Risk

Value Addition:

  • Water reserved for hospitals, sanitation, firefighting.

  • Distribution via controlled public collection points.

• Drivers:

  • Over-extraction of groundwater.

  • Poor urban planning.
