Context
Fresh encroachments and illegal commercial activities have intensified the ecological degradation of , a vital wetland in Andhra Pradesh. Environmental advocacy groups are demanding the immediate enforcement of past directives to dismantle illegal structures. This highlights the persistent tension between commercial interests, political inaction, and the conservation of critical natural habitats.
UPSC Perspectives
Geographical (Ecosystem & Topography)
Wetlands are dynamic ecosystems that serve as natural sponges, absorbing excess rainfall and preventing floods. Geographically, is strategically situated between the delta regions of the Krishna and Godavari rivers, functioning as a massive natural flood-balancing reservoir. The lake drains into the Bay of Bengal through the Upputeru river, maintaining a delicate estuarine balance. Encroachments directly reduce the water-holding capacity (the maximum volume of water a body can store) of the lake. When artificial ponds are constructed by raising mud bunds, the natural flow of water is obstructed, leading to severe flooding in surrounding agricultural lands during monsoons. UPSC Prelims frequently tests the exact geographic locations of such wetlands and their associated river systems.
Environmental (Conservation & Ramsar Recognition)
International frameworks exist to protect wetlands of global importance, most notably the (an international treaty for the conservation and sustainable use of wetlands). Recognized under this convention, the lake is also a notified wildlife sanctuary protected under the , hosting millions of birds including the Near Threatened Grey Pelican (Spot-billed Pelican). The unchecked expansion of illegal aquaculture (the commercial farming of aquatic organisms like fish and prawns) pollutes the water with excess nutrients, antibiotics, and chemical fertilizers. This nutrient overload causes eutrophication (excessive richness of nutrients in a water body, causing dense algae growth and the death of animal life by oxygen depletion). For Mains, aspirants should note how habitat fragmentation and pollution directly threaten the fragile biodiversity of protected eco-sensitive zones.
Governance (Judicial Enforcement & Policy Failure)
Effective environmental governance relies heavily on the strict implementation of judicial and statutory mandates at the grassroots administrative level. The has historically intervened to protect this wetland, notably prompting an eviction drive known as 'Operation Kolleru' in 2006 to forcefully dismantle illegal fish ponds. However, the resurgence of these encroachments over five decades highlights a profound governance deficit (a systemic gap between policy formulation and its on-ground implementation) fueled by local political-economic nexuses. This scenario underscores the practical challenges of enforcing the when local commercial lobbies exert political pressure. For UPSC GS Paper 2 and 3, this serves as a classic case study of how administrative apathy and political inaction can undermine landmark judicial directives and national ecological security.
