- Abstract
An investigation was undertaken to understand the impact of climate change on biomass availability and no assess the pressure of livestock on available total feed and fodder. Biomass productivity of both rice and maize was simulated using DSSAT model. The average biomass productivity of maize single and double cropping system under baseline was 8708 kg/haand 9441 kg/ha and for rice was 4810 kg/ha and4737 kg/ha respectively for baseline period (1980-2009). Simulation of future biomass productivity under changing climatic conditions indicated that it was decreasing in both maize and rice. A decrease of 27.6 and 22 per cent was expected in maize and by 27.2 and 26.5 per cent in rice single and double cropping system, respectively. The results revealed that the livestock production systems need to be adjusted through adoption of possible feed and forage management strategies to reduce the vulnerability to climate change.
