of greenhouse gas emissions from compost application with special
focus on arid
|Abstract:|| Increasing greenhouse gas
emissions are the most important driver of climate change. Different
sectors, such as energy, transportation, industrial production,
agriculture, waste and solvent use contribute to greenhouse gas
emissions. Mitigation of greenhouse gas emissions is very essential in
order to attenuate/decelerate climate change. Therefore it has been a
subject for many research studies in the last decades. |
Composting as an alternative to land filling is globally discussed as a key mitigation strategy, although additional emissions of N2O have to be considered. The agriculture sector causes around 12% of man-made greenhouse gas emissions. A study done by FAO (2014) shows that greenhouse gas emissions increased from 4.6 Gt CO2 eq/yr in the 1990s to 5.0 Gt CO2 eq/yr in the 2000s and further to 5.3 Gt CO2 eq/yr in 2011. Agriculture also contributes to 60% of total anthropogenic N2O emissions and 50% of CH4 emissions. These emissions grew by 17% from 1990 to 2005, by increasing around 60 MtCO2-eq/yr.
The objective of the study is to investigate the greenhouse gas emissions from compost application, with special focus on arid climates. It is aimed to support decision making for compost applications which mitigates the greenhouse gas emissions in arid climates. Experiments have been conducted under stable laboratory conditions. Results will give insight into changes in greenhouse gas emissions according to the different compost and fertilizer applications.
