Abstract

Watershed treatment includes implementation of participatory micro-watershed-based soil and moisture conservation programs and income generation through proper natural resource management areas. This has led to increased productivity and income. Training and holistic management along with aforestation programs has led to reduction of silt flow to the lake. The assessment revealed that land degradation in the drainage basin not only leads to enhanced silt flow into the lagoon but also causes poverty, due to low productivity in the drainage basin. The drainage basin management program is conceived as a long-term participatory process to achieve an environmentally, economically and socially sustainable management of water resources. The present study deals with periodic assessment and monitoring the vegetation cover of the Dengei pahad micro watershed, Khurda District, Odisha, using NDVI techniques. NDVI is the traditional vegetation index used by researchers for extracting vegetation abundance from remotely sensed data. In essence, the algorithm isolates the dramatic increase in reflectance over the visible red to near infrared wavelengths, and normalized it by dividing by the overall brightness of each pixel in those wavelengths. Satellite data of IRS series from 1999 to 2010 and Resources at series from 2011 to 2014 along with other spatial and non-spatial data were used to find out the changes that occurred in vegetation and other land cover categories during the last 16 years. It was analyzed that dense vegetation cover has decreased up to 20.24 Ha in the year 2010 and after the awareness to the local people by CDA, has taken active role to sustain the natural resource and it has shown positive impact after the analysis through Remote Sensing data.Keywords: Micro-watershed, participatory, degradation, sustainable, NDVI, satellite, remote sensing Cite this Article Jajnaseni Rout, Adikanda Ojha, Samal R.N., et al.
