Delhi government officials hold talks with Ahmedabad civic agency officials to introduce bio-remediation, a method by which the latter will be able to clear a massive 35-year-old landfill.
The Delhi government is taking help of the civic agency in Gujarat's Ahmedabad for removal of around 28 million tonnes of waste from the three gigantic landfills in the city — Ghazipur, Bhalswa and Okhla — in adherence to the National Green Tribunal's (NGT) directions.

Centre Grants Tungareshwar, Tansa Reserves 'Eco-Sensitive Zone' Status

The Centre declared two wildlife sanctuaries near Mumbai as 'Eco-Sensitive Zones' (ESZs). There are 11 more such zones in Tamil Nadu and Chhattisgarh.
Tungareshwar Wildlife Sanctuary (TWLS) and Tansa Wildlife Santuary (TWS) are lush green areas spread across several hundred square kilometres in Palghar and Thane districts adjoining Mumbai.
They also serve as the catchment areas for lakes and reservoirs that supply water to the city.
The total protected area of TWLS is around 86 sq km and will have the ESZ of 67 sq km. For TWS, the total area is around 305 sq km with ESZ of around 490 sq km, which will include 150 villages. TWLS and TWS are ranked as major habitats for wildlife.
The Sanjay Gandhi National Park in Borivali, sprawled across Mumbai's north-east and north-western suburbs, is home to around 45 leopards, different varieties of deer, four-horned antelopes, monkeys, Indian Flying Foxes, spot-Striped Hyena and a large number of birds and insects.
Leopards often stray into residential areas like Dahisar, Borivali, Kandivali, Malad, Goregaon, Andheri, Powai, Bhandup, Kanjurmarg and Mulund, and other green areas in the Mumbai Metropolitan Region.
Experts said declaring an ESZ, or a buffer zone, around a wildlife reserve will help conserve the ecosystem since only agriculture, a few small scale industries and minor infra-works are permitted within the ESZ. Maharashtra had proposed the ESZ around TWLS and TWS forests in August 2016.
