Karnataka Sets a Precedent in Waterbody Buffer Zoning

The Karnataka Tank Conservation and Development Authority (KTCDA) has taken an unprecedented step by proposing a scientific revision to buffer zone regulations for waterbodies. This marks the first time a state in India has tailored regulations to the size of waterbodies, aiming to prevent flooding while maintaining natural water inflow.

The proposal introduces a graded buffer system: zero metres for waterbodies up to five guntas, increasing incrementally to 30 metres for lakes exceeding 100 acres. This scientific framework replaces the existing uniform 30-metre rule, enhancing the zoning approach across diverse waterbodies.

KTCDA emphasizes that the revised buffer zones are not for real estate gains but for ensuring public utility and infrastructure development without disrupting water flow. The changes, also reflecting practices from other states like Gujarat and Tamil Nadu, promise to mitigate urban flooding risks.
