Ravine Erosion and Livelihoods in Semi-arid India: Implications for Socioeconomic Development

Abstract

The ravines found along the Chambal River are among the most severe types of gully erosion found in semi-arid India. This paper estimates the extent and areal expansion of ravines over 40 years in the Lower Chambal Valley and provides a classification scheme to understand ravine characteristics in the region. To examine the implications of ravines on socioeconomic development and livelihoods of the people in the area, a mixed method approach has been followed. A combination of spatial and statistical tests has been run to examine the overall status of land degradation and its impact in the area concerned. Village-level socioeconomic data have been integrated with physical and environmental parameters in a GIS environment, which has been supplemented with findings from a qualitative survey in a few villages of the study region. The results show that there is a positive and significant relationship between indices of natural resources availability and socioeconomic development. A majority of villages within ravines were found to be very poor in development. In this fragile environment, people’s livelihoods are being adversely affected because of land degradation.
