The time has come, or one can say it is overdue, that a green belt has to be set up around Angul-Talcher region of Odisha, which is one of the most polluted in India. The people of this region are subjected to air, water, sound and land pollution due to heavy industrialization. A green strategy by planting multi-tolerant species like Banyan, Neem, Mango, Sal and other eco-friendly plants will considerably reduce pollutants which cause contamination by floating in the air, environmentalists opined. No one will deny that over a dozen of open cast mines, thermal power plants and ancillary industries have destroyed the ecological balance in Angul-Talcher industrial belt over the years. The pace of industrialization in Angul-Talcher region is increasing day by day and so the pace of environmental pollution goes up matching with this phenomenon. Studies have revealed that the air of the region is filled with heavy metals and radio active elements that are dangerous for human beings. Environmentalists are of the opinion that the need of the hour is to grow as many ecofriendly plants as possible and this process has to be done scientifically. They said the green strategy formula introduced in cities like Bhubaneswar and Rourkela has shown positive response to counter environmental contamination. The multi-tolerant species have shown high degree of absorption capacity to neutralize toxic effects in the air.
Species Suitable For Angul-Talcher:
1.Neem saplings are ideal to be planted in buffer zones for green cover. The buffer zones are between industries and human habitation.
2.Mango trees, apart from giving fruits, provide wider canopy which are suitable for birds to build their nests. This helps to boost biodiversity in the region.
3.Banyan trees and Peepal trees are also suitable for increasing biodiversity which release of oxygen day in and day out.
4.Sal trees are naturally grown in Angul district in Odisha. Theses species are proved to be the best among those which act as pollution repellants. But, unfortunately, Sal forests are denuded due to extensive mining operation in Angul-Talcher and Chhendipada regions in the state.
5. Jamun species are fast-growing as well as fruit bearing and widely acknowledged as for their medicinal value and air purification capabilities.
6. Karanja is also known as high tolerant tree and suitable for industrial areas to contain high pollution impact.
Green Cover Strategy:
The strategy should be carried out to plant saplings in close proximity to opencast coal mines and thermal power plants in Angul-Talcher area. The saplings must be Sal and Banyan for high absorption of pollutants floating in the ambient atmosphere. Mixed species like Mango, Peepal can be opted for colonies and residential areas as well as parks for purifying air quality. Due attention must be given to protect biodiversity by planting species which are known to have wide canopy to be used as nests for birds. However, the strategy to counter contamination effectively rests on proper participation of different stakeholders in the region such as local communities, non-government organizations, academic institutions and the industries.
Sal Forest Dwindling:
Extensive mining operation in Angul-Talcher-Chhendipada region has almost wiped out Sal species which have high tolerance to air pollution. Social activists working in the region have alleged that as many as one lakh Sal trees have been chopped off to make way for open cast coal mines in Chhendipada area. The region will witness over a dozen coal mines denuding large tracts of lush green Sal forest and displacing hundreds of thousands of families from their homestead land. The widely advertised slogan 'Ek Ped Maa Ke Naam' (One tree in honour of mother) by the government has come in for criticism following widespread felling of Sal trees from reserved forest areas in Chhendipada forest range for handing over the land to mining barons.
