This course will provide knowledge on the processes underlying GHG emissions and soil C sinks, measuring methodologies and modelling tools in cropping systems. Methods for national GHG inventories and mitigation options analysis, including socio-economic assessment, will be presented. Practical work based on real case studies in Mediterranean conditions will also be organized. At the end of the course participants will have: – Better understanding of the sources and drivers controlling GHG emissions from agricultural systems. – An overview of state-of-the-art methods for measuring GHG emissions and soil C changes. – Improved skills in the use of simulation models and tools for estimating GHG emissions and soil C changes at different scales. – Insights on GHG mitigation options and their socioeconomic assessment. – Criteria for designing and improving national inventories. – A holistic view of available tools to support informed decision making.
