IMPACT ASSESSMENT OF IRRIGATION DEVELOPMENT IN VEDGANGA BASIN--A GEOINFORMATIC APPROACH

摘要

Irrigation development has been conceived as one of the important rural development programme in India where the rainfed agriculture is characterised by low productivity, degraded natural resources and widespread poverty. Recognising the importance of irrigation development for their perceived ability to promote agriculture and rural development, both Central and State Governments make huge investments in irrigation development. As million of rupees are invested, it is essential that the programmes have positive impact. It is in this context the Impact Assessment of irrigation development and management assumes importance. In this paper an attempt has been made to assess the impact of medium and minor irrigation project of watershed development in Vedganga basin. This study is based on scientific parameter; NDVI and land use/land cover change detections etc. A scientific methodology is developed to monitor assess and evaluate the irrigation development programme. The analysis reveals that even though, the large amount has been invested the impact is not satisfactory.
