Guwahati, June 8: A study conducted by the Assam forest department on the impact of the blowout of OIL India Limited’s Baghjan well on the ecosystems in and around the site in eastern Assam’s Tinsukia district has been estimated to cause losses to the tune of Rs 25,050.61 crore.
The study titled, “Ecology & Economy: Lessons Learnt from Baghjan Blowout”, and authored by chief wildlife warden, M.K. Yadava, who was appointed by the state government to investigate the impact of the blowout on the ecosystems around Baghjan revealed that there has been a 55 per cent loss of biodiversity owing to the blowout.
The study adopted the ‘shadow pricing’ route, wherein, in the cost of one item, cost of other items for which price is not known, could be subsumed.
Apart from “uncountable losses”, a limited number of “countable” damages which could be directly and rationally arrived at were listed.
The study revealed that the blowout, explosion and fire (from May 27, 2020 to November 15, 2020) directly impacted 40 listed scheduled animals in the Wildlife (Protection) Act, 1972, belonging to different classes, orders, genera, families and species.
“Habitat of these animals was disturbed, destroyed, the young ones, larvae, eggs and nests damaged. The actual visual count of dead animals listed in the Schedules of the Wildlife (Protection) Act, 1972 was found to be 91, including one Gangetic River Dolphin and two Hoolock Gibbons (mother and baby),” it informed.
In addition to these deaths, there were counted deaths of 25,825 animals (wildlife) belonging to 41 genera/ families.
“Condensate oil spread to a large area of 13.85 sq km, of which 7.97 sq km got burnt almost fully, 1.02 sq km in the surroundings got burnt partially, Secondary affected areas spread to 13.75 sq km. Dibru-Saikhowa National Park got impacted to the extent of 12.07 sq km,” the study revealed.
A total wetland area of 16.32 sq km got affected, grassland area of 5.23 sq km, rivers/ streams 19.76 sq km and forest areas 2.13 sq km got impacted adversely, it added.
The study blamed the faulty nature of environment clearances due to misreporting in the environmental impact assessment, which undermined the possibility of a blowout and the destruction it caused to the ecosystem.
