Preserve and
Protect Biodiversity

Nature's rich biodiversity not only provides us with food and water but a cornucopia of scenic delights from the snow-capped mountains to the mighty oceans, deep forests and a treasure trove of wildlife.

Ecosystem services worldwide are worth nearly twice the Global National Product (GNP) at around $44 trillion, nearly double the value of what humans produce each year!

The irreversible loss of plant and animal species, habitats and vital crops, along with global climate change represents a biodiversity crisis that is putting all of mankind at risk.

The UN Convention on Biological Diversity talks of 13 million living species, of which only 1.75 million have been named and recorded.

PROBLEM

Underground Bord and Pillar mining needs porous barricades to prevent land subsidence and degradation. These are generally made of timber props and bamboo mats.

SOLUTION

A suitable, environment-friendly and cost-effective method was to erect barricades by using 6 mm diameter flexible steel ropes and geo-textile mats. This sustainable solution minimised environmental impact and indirectly reduced greenhouse gas emissions.

IMPACT

This new methodology of barricading has been deployed at our Jharia Divison and has completely replaced the use of timber props and bamboo mats.

CHALLENGE

To enrich the biodiversity in the Saranda forest region near Noamundi.

 

SOLUTIONS

A 'niche' is the space selected by any animal or plant for its feeding, resting, sleeping, nesting, breeding and growing (plants). These can be on the ground, tree trunk, branches, twigs and leaves or different parts of a rock and other substrate. The concept of enhancing nesting niches is by creating nesting spaces for biodiversity to thrive.

A biodiversity assessment revealed that at Noamundi there are 18 species of hole nesting birds. With guidance from the International Union for Conservation of Nature (IUCN), Noamundi has developed 200 nest boxes and placed it at various locations in reclaimed areas, the Tata Steel township and in nearby villages.

IMPACT

The installation of artificial nesting on tree tops has added to the resting space for birds and provided a secure breeding ground.

Bird activity spotted in 80% of the installed nest boxes. This niche nesting programme is being replicated at our other mining locations.

PROBLEM

Reclamation in the worked-out mining benches for plantation.

SOLUTION

Using the 'pitting and planting' method, plantation have been developed on flat areas on overburden. Reclamation is done by making 1.5 ft pits, six feet apart, and filling them with earth, sand and cow dung. Neem cake powder is applied to protect the saplings from white ants. Some 27 local species were selected for plantation for which no chemicals were used for pest control. Regular weeding is undertaken to enhance plantations and control growth of invasive species.

IMPACT

Conversion of the mining land into a thick biomass cover provides a good habitat for the local species with social, environmental and governance benefits. It provides food security to the local species and the local villagers. Employment opportunities, for local villagers, have been generated in horticulture and plantations.
