We are identifying opportunities for mitigating greenhouse gases from agriculture. We are analysing plant-microbe interactions and soil properties to better understand how N2O emissions may be reduced and carbon sequestered to helpre-shape policies and practices.
Nitrous oxide (N2O) is a very potent and dangerously increasing greenhouse gas (GHG), which has 300-fold greater global warming potential than carbon dioxide and an atmospheric lifetime of ~150 years.
More than 80% of N2O emissions globally are associated with the agricultural and waste-treatment industries, in large part because of the increased application of nitrogenous fertilisers onto soils that began in the early 1900s. Efforts to reduce N2O emissions require a better understanding of the factors that influence the production of N2O by bacteria, and closer interaction between this understanding and the policies and management techniques that regulate a range of agricultural and waste-treatment practices.
Globally we stand on the brink of some major opportunities in agriculture and food production for mitigating the production of GHG. This Tyndall-Fudan research project will identify and highlight these opportunities. It will look at plant-microbe interactions and soil properties using metatranscriptomics methods and isotope measurements to establish how N2O emissions may be reduced and C sequestered, and integrate this knowledge with agricultural transitions and urbanisation to help re-shape agricultural policies & practices.
