Water crisis in Bengaluru linked to urbanization of Kodagu

Subject: Geography

Section: Indian Physical geography

Context:

The Save Kodagu and Cauvery Campaign has raised concerns about the adverse effects of rampant commercial land conversion and urbanisation in Kodagu, the birthplace of the Cauvery River.

Save Kodagu and Cauvery Campaign:

Aim:
- This campaign highlights the critical role of Kodagu as the principal catchment area for the Cauvery, which significantly contributes to the water supply of Bengaluru.
- The Save Kodagu and Cauvery Campaign’s concerns underscore the need for sustainable development policies to preserve the Cauvery’s water supply for Bengaluru and other dependent regions.
Cause of water crisis:
- The continued urban expansion and environmental degradation in Kodagu could lead to a scenario where the district’s cities grow significantly, potentially affecting the water supply to Bengaluru and neighbouring regions.
Consequences:
- The campaign highlighted the potential long-term consequences of unchecked urbanisation in Kodagu, such as the transformation of several areas into large urban centers and the possible escalation of the population.
- Such developments could strain water resources, requiring drastic measures like invoking the National Disaster Act in the event of drought conditions.
- This could severely impact local agriculture, particularly coffee production, by restricting water usage for irrigation.

Kodagu- Place of origin of Cauvery river:

Kodagu, which is the main catchment area as well as place of origin of the Cauvery river, is under stress due to the sensitive ecosystem.
Located in the Western Ghats region of Karnataka.
The Krishnaraja Sagar (KRS) reservoir is located downstream the Cauvery river.
