Mine Land Reclamation-A Case Study of Sesa Goa Ltd

摘要

The disturbance of land surface due to mining alters the potential for revegetation growth, such that it is not possible for pre-existing plant community to be exactly recreated Although the degraded mine wasteland can be stabilised, the use of expensive high input methods is inappropriate for developing countries where there is a general reluctance to increase mining cost because of limited financial resources. Low input approach include proper planning of waste dump using locally available boulders and jute or coir for erosion control, use of hardy, climatically adopted species having low nutrient requirements and use of Nitrogen -fixing plants, especially Legumes to provide sustainable source of Nitrogen. Rehabilitating mining sites is a way to provide speedy vegetation. It aims to achieve vegetative cover within few years so that later succession will be quick. The ecosystem should be sustaining with increase in Bio-diversity and capable of maintaining itself even if unattended Achieving a self-sustaining ecosystem in degraded areas requires careful planning prior to the start of mining activity. Thus mining industry will not lead to degradation of environment if a combination of imagination, care and scientific skill is employed. Infact the sites could become more productive than pre- mining.
