Biomass surplus in India is recognized as an important renewable source for energy for captive and grid linked energy application. This background necessitates nation-wide assessment of different types of agro biomass distributed geographically. Assessment needs crop parameters- Crop Residue Ratio (CRR), Crop Yield (Tons/Hectare), Residue Yield (Tons/Hectare) and Biomass Utilization [Kilotons/Year]. This was made available through taluk and district surveys conducted across the country initiated by MNRE (Ministry for New and Renewable Energy). National Focal Point (CGPL, IISc) has analyzed, verified and integrated these crop related data (Year 2000- 04) for all states of India into a data base to be used for creating the spatial atlas- Indian Bio-Residue Map (IBRM). The spatial maps providing the Land use were obtained from ISRO (Indian Space Research Organization) for the year 1999-2000 through their satellite imagery at a ground resolution of 184x184 m. Based on the fact that the total change in the agricultural area will not be considerable within 10 years, the crop data has been distributed on to the map. This was then set into GIS (Geographical Information System) by the NFP to use the statistical crop data for spatial distribution at district level. The outcome of this is as an electronic atlas being made available over Internet and a stand–alone application that can work on a Desktop Computer. The power potential for India is estimated at around 16000 MWyre after assessing the agro-biomass from the atlas.
