Agricultural biomass has immense potential for power production in an Indian state like Punjab. A judicious use of biomass energy could potentially play an important role in mitigating environmental impacts of non-renewable energy sources particularly global warming and acid rain. But the availability of agricultural biomass is spatially scattered. The spatial and temporal distribution of biomass potential from crop residues was studied at district level for calculating total and surplus biomass using Geographical information system (GIS). The change in biomass intensity, cropping intensity and percentage area under different crops over a period of time from 2001 to 2011 was also studied. The total potential of biomass in Punjab was 54.54 million tones. The average biomass intensity in Punjab increases over the year from 9.3 tonne per ha to 16.47 tonne per ha, the increase was due to increase in cropping intensity and also the change in area and production of major contributors of biomass. The surplus biomass for energy generation was estimated at district level and it was found that out of the total biomass potential, about 61.78 per cent of biomass (33.69 million tons) was surplus for energy generation. The major contribution was from paddy straw (63.97 per cent) followed by wheat straw (20.33 per cent), paddy husk (11.98 per cent), cotton sticks (2.4 per cent) and maize cobs (0.378 per cent). The maize stalks were completely utilized and are not available as surplus. The percent area of paddy has increased from 58.31 to 67.96 per cent and wheat increased from 80.17 to 84.41 per cent from year 2001–02 to 2010–11. The decrease in area under cotton was 100 per cent in Jalandhar over the decade followed by Moga (79.02 per cent) and Faridkot (58.45 per cent) districts. The area under sugarcane has been completely wiped in Bathinda, Moga, and Faridkot and Sangrur districts over the decade whereas other districts Ferozepur, Muktsar and Amritsar have witnesses increase in area. The cropping intensity increased linearly form 187.43 to 189.56 per cent in this decade. The estimated biomass intensity of unused biomass for energy generation lies between 4.80 tonne per ha to 10.96 tonne/ha. On the basis of total availability of biomass for power generation using GIS, spatial maps of biomass management for power generation of Punjab was also developed.
