In the present scenario climate change has become a global environmental concern. Its impacts are far and wide, which will be witnessed by all the entities present in the region. The United Nation Framework on Climate Change (UNFCCC) defines climate change as “statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer)”. These changes may be due to natural internal processes or external forces or due to persistent anthropogenic changes that ultimately impact the composition of the global atmosphere or land use patterns. The World Meteorological Organization defines the classical period to study climatic variables is 30 years. The changes can be seen through the statistical description of the surface variables such as temperature, precipitation, and wind. Inter – Governmental Panel on Climate change (IPCC) mentions that the warming of the climate systems is being witnessed in the present century. There have been observations that the global average air and ocean temperatures are increasing resulting in the rise of global average sea level and widespread melting of snow and ice. IPCC also observes that over the last 50 years some extreme weather events have changed in frequency and/or intensity as well. To address the challenges being posed by climate change the Government of India too has adopted a National Action Plan on Climate Change (NAPCC) since 2008. To respond to climate change the NAPCC has sets eight priority missions to respond to climate change. These missions include the National Missions on - Solar Energy, Enhanced Energy Efficiency, Sustainable Habitats, Water, Sustaining the Himalayan Ecosystem, Greening India, Sustainable Agriculture and Strategic Knowledge for Climate Change. It is seen that climate change adaptation and vulnerability identification can both be done more effectively at local level. Hence Rajasthan like each Indian state has prepared a detailed State Action Plan on Climate Change (SAPCC) to identify state-specific risks, impacts and opportunities posed by climate change. This thesis title – „Vulnerability and Adaptation to Climate Change in the Context of Water Resources with reference to Rajasthan‟ looks in to the environmental and water resource scenario of Rajasthan and the statistical changes reflected in the surface climatic variables of temperature and rainfall. The study observes these climatic variables during 1980 and 2009 i.e. for 30 years.
