Agro-environmental indicators. New IACS VISION in ACTION – NIVA
Résumé
Context and objectives: Agricultural activities have a strong impact on the environment ; UC1b has developed a set of indicators based on existing scientific methods and on data widely available in Europe (IACS, Sentinel-2 images, topographic data) ; Computation tools are open-source and available on the NIVA GitLab : gitlab.com/nivaeu. These indicators may contribute to assess some of the new CAP objectives and some Sustainable Development Goals Carbon indicator: annual CO 2 flux due to crop vegetation cycle . CO 2 flux takes into the account the CO 2 emitted in the atmosphere (plants and soil respiration) and the CO 2 stored by plants due to photosynthesis. The computation of CO 2 flux is based on an empirical method: for main crops, annual CO2 flux depends on the number of days with active vegetation. This number of days is estimated from NDVI temporal series (from Sentinel-2 images). The computation tool has been tested on various areas in Europe (France, Denmark, Netherlands, Spain) NIVA H2020 PROJECT www.niva4cap.eu Spanish results in Castile and Leon
