Background: Methane, considered second major greenhouse gas after CO2, with significant fluxes from agro-ecosystems is held responsible for global warming and climate change. In order to address this environmental challenge, world-wide attention continues to focus on this important topic. Field data are provided on much-needed information on this greenhouse gas from little–explored hilly and temperate region of Kashmir Himalaya, India.
Methods: Methane determination was done by collecting the gas samples using closed chambers, and analyzed by Gas Chromatograph (Shimadzu 14BPSTF) fitted with flame ionization detector (FID).
Conclusions: Rice in some circles is condemned as the major culprit for the global warming, climate change and environmental degradation. The application of biodigested manures over the fresh organic manures like farmyard manure, green manure etc constitutes one of the amelioration mechanisms to retard methane emission in rice cultivation. As such rice (and livestock) deserves adequate attention to target CH4 emission reduction. Livestock are well implicated in highest methane emissions as compared to other subsectors of agriculture. However, there is a need to strike a balance between food security through rice protection and sustainability of resource-base and global climate.
