Agriculture - GHG emissions - Global ecosystem models - Mitigation - Soil management
Strategies on agricultural management can help to reduce global greenhouse gas (GHG) emissions. However, the potential of agricultural management to reduce GHG emissions at the global scale is unclear. Global ecosystem models often lack sufficient detail in their representation of management, such as tillage. This paper explores whether and how tillage can be incorporated in global ecosystem models for the analysis of nitrous oxide (N2O) emissions. We identify the most important nitrogen processes in soils and their response to tillage. We review how these processes and tillage effects are described in field-scale models and evaluate whether they can be incorporated in the global-scale models while considering the data requirements for a global application. The most important processes are described in field-scale models and the basic data requirements can be met at the global scale. We therefore conclude that there is potential to incorporate tillage in global ecosystem models for the analysis of N2O emissions. There are several options for how the relevant processes can be incorporated into global ecosystem models, so that generally there is potential to study the effects of tillage on N2O emissions globally. Given the many interactions with other processes, modelers need to identify the modelling approaches that are consistent with their modelling framework and test these.

FACCE ERA-GAS (ERA-NET Cofund for Monitoring & Mitigation of Greenhouse gases from Agri- and Silvi-culture), together with the ERA-NET SusAn, (Sustainable Animal Production Systems) and ERA-NET ICT-AGRI 2 (Information and Communication Technologies and Robotics for Sustainable Agriculture) organized a joint workshop on 29-30 November in Potsdam to identify promising approaches to reduce GHG emissions in livestock production. The joint workshop, the first of its kind involving three ERA-NETs, had close to 70 participants from 22 different countries. The three ERA-NETs have already identified a number of potential areas of synergy. This workshop explored one of those areas in detail: Comparison of animal production systems with respect to GHGs. Particular attention was paid to the following two sub-topics: (1) Production technology and management (e.g. housing systems; optimal field and grazing management), and (2) Breeding, physiology, feed & nutrition.The outputs of the workshop will help to set the research priorities for future joint calls and other activities between the three ERA-NETs.

Energy efficiency - GHG emissions - Sustainable production
Greenhouse production has increased over the last decades in the Mediterranean region. Greenhouses allow protecting crops from adverse climate conditions, creating microclimate conditions appropriate for obtaining high production with high quality all over the year. However, greenhouse production is generally associated with high environmental impacts due to the use of high amounts of resource inputs and the high quantity of waste generated. Sustainable greenhouse production is nowadays a goal and can be achieved by using appropriate technologies such as innovating crop practices and environmental control techniques allowing reducing agro-chemicals, water, and energy consumption. Organic farming is based on methods and practices that try to protect the environment (soil, water, air), which includes limitation on the use of synthetic pesticides and fertilizers and the use of onsite resources, such as livestock manure for fertilizer. Demand for food produced without using agro-chemicals has increased; usually these products are sold at high price and associated to a particular nutritional value, taste and health. It is generally associated with lower yield and better quality. Greenhouse organic farming is not widely applied as farmers believe that yields are strongly reduced. However, there is a market opportunity to organic farming as a result of higher product prices and consumers demand. In order to compare the overall efficiency of crop farming systems, it is vital to consider energy consumption and efficiency. In this work, a case study is analysed in terms of energy consumption and greenhouse gas emissions (GHG). The data were obtained directly from the grower and the main objective of this work was to characterize the organic greenhouse production system. The most important inputs were identified and compared with others obtained with conventional greenhouse production. Results showed that organic greenhouse uses less energy ha-1 and t-1 of produced tomatoes than the conventional greenhouses.
