With the help of geospatial technology, it is possible to generate and update information about natural resources, in spatial format, at much more frequent intervals, so enabling proper inventory and management of natural resources, said P. Subbian, Registrar, Tamil Nadu Agricultural University (TNAU).
Inaugurating a 21-day summer training on “Geospatial Technologies and Applications” at TNAU, he said the Indian geospatial industry’s current annual productive capacity was nearly Rs. 4,000 crore. “The industry is expected to annually grow at a cumulative growth of eight per cent to a productive capacity of Rs. 5,820 crore by 2014. Geospatial technology includes three components, viz., Remote Sensing (RS), Geographic Information System (GIS), and Global Positioning System (GPS),” he said.
The scope for applying geospatial technologies was enormous in Indian agriculture, especially in areas of watershed management, crop acreage and yield estimation, drought monitoring, pest and disease monitoring, soil resource mapping and command area management, which would help enhance sustainable agriculture, he added. “It is found that the use of GIS and GPS for precision farming, especially for fertilizer application, reduced total fertilizer expenditure by up to 10 per cent a year, besides enhancing yield by 15 per cent, has been profitable,” Mr. Subbian said.
