dominating countries like India. 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. The

a large variety of natural resources thus required to utilize in sustainable manner for proper
development.The fifth chapter- Factors affecting soil erosion deals with the factors such as
rainfall, runoff, wind, soil, slope, plant cover and presence or absence of conservation measures
