BENGALURU: Following a dispute mirroring the Aravalli controversy, members of a Supreme Court-appointed panel will inspect Bannerghatta National Park Friday after a plea against a 2018 govt move to cut the eco-sensitive zone (ESZ) around Bengaluru's green backyard. The park is facing pressure from mining and real estate interests eyeing its contiguous landscape. At the core of the standoff is govt's move to drastically shrink ESZ from 268.9sqkm to 168.8sqkm and curtail its width from 4km to just 1km.A group of citizens and activists led by K Belliappa had approached Supreme Court in May 2025, arguing the reduction undermines the purpose of an ESZ. On Friday, members of the Supreme Court-appointed Central Empowered Committee (CEC), led by Chandra Prakash Goyal, will survey the park and speak to senior Karnataka officials, including the chief secretary, to assess the ecological impact of the reduction.

Vanishing buffer

In a preliminary notification in June 2016, the Union environment ministry had in consultation with the state proposed declaring 268.9sqkm around BNP as ESZ. However, the final notification of Nov 2018 sharply curtailed the protected area - a decision the petitioners alleged was influenced by real estate developers and mining and quarrying interests. They contended that several ecologically sensitive pockets surrounding well-documented elephant corridors were excluded from the final notification.

Kiran Urs, a member of the Bannerghatta Nature Conservation Trust (BNCT), said ESZ reduction appeared to be an attempt to legitimise existing ecological violations. "The pockets excluded from the final notification contain active quarries, and there were efforts to build a township along the boundary, which will inevitably exert immense pressure on the ecosystem," Urs alleged. Somashekhar, a farmer from Kaduchikkanahalli near the park, claimed he came under pressure to sell his land even after the final ESZ notification. "However, I continue to hold my land and grow ragi," he said. Keerthan Reddy of BNCT described the park as one of the best ecological gifts for a burgeoning Bengaluru. "No other city can boast this vast green landscape in its backyard, dotted with a salubrious population of tigers, elephants, leopards, and countless other species of flora and fauna.

The city is already witness to rising incidents of human-animal conflict, and violations like these would only add to the problem," Reddy cautioned.
