Thus it is essential to framing strategy to combating problem of soil erosion in the study area. It consist description about Geographical profile of Shekhawati region, review of related literature, statement of the problem , significance of the topic, description of respective study area, research design, explanation of terms used in study and chapter scheme. The second chapter- Geology and Climate deals with the Geological structure of Shekhawati. According to Hakim Yusuf Jhunjhunuvi Shekhawati derives its name from Persian language word ’Sheekh’ which means ’Sand deposited on the coastal area of sea’.of the study area.
