Application of FSSIM in two test case regions to assess agro-environmental policies at farm and regional level. PD 6.3.2.2

Résumé

This deliverable presents the results of the first application of the bioeconomic farm model FSSIM for a set of farm types representing the arable farming systems in two Test Case regions of the SEAMLESS-IP project: Midi-Pyrénées (France) and Sikasso (Mali). This application is performed through the FSSIM standalone version (i.e. outside the SEAMLESS-IF system) and it has two aims: (i) to test the capacity of FSSIM to capture the diversity of conditions from the North to the South, regarding biophysical and socio-economic aspects; and (ii) to provide a first example of assessment at the field and farm levels of the economic and ecological impacts of specific agricultural and environmental policies and technological innovations. The impact assessment at the field level was done through the biophysical model CropSyst, used as a substitute for APES, which is not yet operational for an application. FSSIM is a comparative static mathematical programming model which seeks to capture resource, socio-economic and policy constraints and the major farmer’s objectives. It was designed to be sufficiently generic and flexible to be applied for all relevant farming systems, easily transferable between different geographic locations, reusable and with a rich usage comfort. The simulated scenario in the French region (Midi-Pyrénées) is focused on the adoption of the Nitrate Directive (91/676/EC). The Nitrate Directive is an environmental measure designed to reduce water pollution by nitrate from agricultural sources and to prevent such pollution occurring in the future. The CropSyst-FSSIM-Indicators modelling chain was used to compare a baseline scenario driven by the CAP reform, and a policy scenario combining the CAP reform with the application of the Nitrate Directive and the adoption of alternative crop management. This modelling chain was operated “manually”, i.e. using specific databases filed by one component for the next one, but in a manner consistent with the future applications done inside SEAMLESS-IF when the modelling chains will be operational. The tested scenario in the Malian region (Sikasso) is based on the adoption of new cropping techniques, more efficient and suited to a wide range of socioeconomic and biophysical conditions. These techniques are usually designed at the plot level within research stations and sometimes in farmers’ plots. FSSIM was used in this scenario as a tool to assist and establish a dialogue between agronomic research and farmers, in order to help the adoption or design processes of these new cropping techniques. After a brief description of the FSSIM framework, particularly model design, specification and components (farm activities, resource constraints, policies specification and objective function etc.), sections 3 and 4 present the results of the application for the two Test Case regions respectively. Each section exposes the context, the tested scenarios, the required input data, the procedure followed for running the model (i.e. specification of components, modules and calibration procedure used) and the results of the application. The conclusions, in relation to the comparison of the scenarios and the implications for future FSSIM development and integration into SEAMLESS-IF, are given in section 5
