Résumé
Climate change plays a pivotal role in the world. Many scientific research projects are being proposed and many researchers came to know about the importance studying the climate change. It has produced many positive as well as negative impact in the world. India is not an exception to the climate change. India is a tropical and agrarian country. It is solely depends on the seasonal monsoon rainfall for cultivation. Changes in climate shows huge impact on agricultural production, so the farmers are worst affected. Therefore, there is a need to assess the climate change and strategies adopted by the people to improvise rural livelihoods. This study mainly focuses on the impact of climate change (rainfall and temperature) on cultivable/ crop land, wasteland/ fallow land, water bodies and depth of Ground Water Level (GWL) in Tamil Nadu state, Dindigul district and study villages. For the study, district-wise rainfall and temperature data from 1901 to 2009 (109 years) covering Tamil Nadu State were downloaded from India water portal website. Station-wise rainfall data from 1981 to 2010 for the Dindigul district were acquired from the Statistical Department, Collectorate, Dindigul District. Temperature data were purchased from the Public Works Department (PWD), Tharamani, Chennai. The state and district rainfall data were further classified into two indices namely, Standardized Precipitation Index (SPI) and Indian Meteorological Drought (IMD) Index. State level ground water data from 1990 to 2008 were collected from Tamil Nadu Water Supply and Drainage Board (TWAD) website. District level ground water data from 1990 to 2009 were gathered from the Statistical Department, Collectorate, Dindigul District. For the village-wise depth of GWL for the year 1990 was collected from the field experience of the land owners, farmers and elders in their family. The depth of GWL data for 2014 was collected using field survey method. The sample well locations were identified using Global Positioning System (GPS).
