Terrestrial ecosystems can be either greenhouse gas (GHG) sources or sinks. Ecosystem management in i.e. forests, croplands, grassland, mires, rangelands amongst others largely affect the net GHG exchange, encouraging both sources and sinks, or even leading to changes in the sign of the net GHG budget. With this session we aim at understanding how management activities in terrestrial ecosystems modify GHG exchanges of the three major GHGs: carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). We are particularly looking for in-situ measurements (both short and long-term) on either a single GHG, or studies that jointly assess the three of them. Direct comparison studies of managed vs. unmanaged systems are further encouraged. We further invite contributions that aim at combining measurements with modeling approaches, and/or those that are trying to disentangle how management practices modify the processes responsible for GHG production and consumption at the soil, plant or ecosystem level. As an output if this session we anticipate, (1) learning about individual approaches currently being used to better understand the effects of management activities on GHG budgets, and (2) to consolidate information and develop standardized guidelines for existing and future studies allowing for direct comparison of individual results.
