Study of Impact of Estimated Climate Change on Monsoon Rainfall in Maharashtra

Introduction: Climate change is one of the main environmental challenges facing the world today. India is facing several problems. Climate change is associated with various adverse impacts on agriculture, water resources, forest and biodiversity, health, coastal management and increase in temperature. United Nations Statistics Division (UNSD) recognized the subject of Climate Change as one of its priorities in the Environment Statistics. Climate Change comes under the ambit of the UN framework Convention on Climate Change (UNFCCC) wherein different countries are required to report their Green House Gases (GHGs) emission to the UN. There is also Inter Governmental Panel on Climate Change (IPCC) which reports to UNFCCC. Decline in agricultural productivity is the main impact of climate change on India. A majority of population depends on agriculture directly or indirectly. Climate change would represent additional stress on the ecological and socioeconomic systems that are already facing tremendous pressure due to rapid industrialization, urbanization and economic development. The Intergovernmental Panel on Climate Change projects that the global mean temperature may increase between 1.4 and 5.8 o C by 2100. This unprecedented increase is expected to have severe impact on the global hydrological system
