Climate Change: Evaluation of Ecological Restoration of Delhi Ridge Using Remote Sensing and Gis Technologies

Over exploitation of land, forests, water and air and the failure to tackle the problem of ecological degradation have exposed humanity to the threat of climate change. The atmospheric pollution is increasing, largely because of human activity. Climatic importance is becoming clear, and heightens rather than reduces our concern about anthropogenic climate change. Delhi Ridge forest cover has failed to meet reduction targets for greenhouse gases emission in the Delhi City due to constant concrete jungle sprawl over the periods. Direct aspects of reducing climate change include investment in technology to combat emissions; appropriate building and settlement design, fuel-efficient transportation; and reducing fossil-fuel inputs to industry, etc. Whereas, indirect possibilities include the adoption of landuse practices over Delhi Ridge that sequester high volumes of carbon e.g. afforestation, forest conservation and ecological restoration. Little action has been taken to limit greenhouse gases emission from fossil fuel consumption. Over the Delhi Ridge, there is less concern with ecological change, especially in the face of rapidly growing population of the Delhi City. It must be recognised that an almost all-human activity includes either directly or indirectly caused environmental pollution. However, the vulnerable input of climate change on Delhi Ridge includes ecological imbalance, deforestation and CO 2 effects etc. Although climate change has a wide range of adverse impacts on Delhi Ridge environment, a bigger threat come from other factors, such as population growth, land encroachments, quarrying/mining activities, urbanisation and industrialisation and social and political conditions.
