Intensification of agriculture has been proposed as one way of minimizing emissions per unit of product, apparently legitimizing the ongoing structural changes in agriculture. We have investigated the relationship between the farming intensity and the nitrogen (N) dissipation by calculating the overall N emission factor (E: total N surplus per unit of N in the produce) from several studies of d...

Livestock is a vital source of methane and nitrous oxide gas which are considered as hazardous greenhouse gas (GHG) causing global warming. This study was conducted to assess GHG emissions from different livestock categories of different (small, medium, large) dairy farming in Bangladesh by using IPCC guideline 2006 and CIGR 2002. The emission rate of CH4, N2O (mainly emits from manure) is incr...
