The detection of climate change is the process of demonstrating that an observed change is significantly different from what can be explained by natural variability. It does not necessarily imply that its causes are understood. The climate change can be attributed to anthropogenic causes and at the same time there are non-climate drivers such as land use, land degradation, urbanisation and pollution, affect systems directly and indirectly through their effects on climate.
The socio-economic processes that drive land-use change include population growth, economic development, trade and migration, which are proceeding at an unprecedented rate in India. Land-use changes hamper range-shift responses of species to climate change, leading to an extra loss of biodiversity. Additional land-use changes have been linked to changes in air quality and pollution taht affect the greenhouse process itself. It can also strongly magnify the effects of extreme climate events, e.g., heat mortality, injuries/fatalities from storms, and ecologically mediated infectious diseases.
