This deliverable describes a typical meso-level application of SEAMLESS-IF. This application serves two main purposes within the SEAMLESS project. First of all it served as Test Case 2 (TC2) to test the various prototypes delivered by the SEAMLESS project and guide the development of the framework by identifying the requirements for a real-world application of the framework for ex-ante policy and technological innovations analysis. The second purpose of this application and main focus of this deliverable is to illustrate the potential use of SEAMLESS-IF to adress meso-level environmental questions across domains and scales. This deliverable builds on deliverables prepared throughout the SEAMLESS project, compiling and updating the essence of each of these individual deliverables to a final application with SEAMLESS-IF. The deliverable highlights the potential of SEAMLESS-IF to analyse meso-level incitation for better water and nitrogen managements. For this purpose three scenarios have been defined, combing different water and nitrogen managements such as suggest to improve nitrogen management for cereal crop based on simplify N balance. The objective of this scenario is to calculate new amounts of irrigation based on plant available water (PAW) which will be daily estimated by using the APES model. The last scenario is a combination of the previous two scenarios. The CAP2003 applied with 2013 conditions, by including exogenous driving forces, is taken as a reference. After a brief description of the Nitrate Directive and Water Framework Directive and their main measures in order to reduce nitrogen leaching and water consumption, a detailed description of the three modelling phases of SEAMLESS-IF is given. For each part, the main elements and data needed for each scenarios is described.
