Abstract:
The mitigation of GHG emissions from anthropogenic ecosystems is one of a challenge for following decades. Successful GHG emission mitigation scenarios can be developed if there are tools to predict GHG emission trends according to climate, soil conditions, farm management practices, and other factors. One of the essential GHG emission sources is managed agricultural soils, and the most important factors are soil conditions, soil moisture, and temperature. The conceptual hydrological model METQ has been created under the leadership of scientists at Latvia University of Life Sciences and Technologies and validated for runoff modelling. The development of the conceptual hydrological model METQ by adding additional ecosystem modules is complex. However, the conceptual approach and developed algorithms allow using of this model for ecosystem modelling. The aim of the study is to establish a conceptual framework of GHG emission calculation module integration in the conceptual hydrological model METQ for the assessment and forecasting of the impact of climate change, land use, farming systems, and other factors on GHG emissions. The developed GHG emission calculation modules are designed in two groups. The first group is emissions from the soil, where the GHG emission calculation modules are connected to the soil active layer calculation algorithm of the conceptual hydrological model METQ. The second GHG emission calculation module is indirect N2O emissions from water bodies, where the GHG emission calculation algorithm is connected to the conceptual hydrological model METQ calculation algorithms. Integration of the GHG emission calculation into the conceptual hydrological model METQ requires the rewritten code of the existing modelling platform and the creation of an open platform for adding new calculation modules.
