A complete satellite-based grassland monitoring service

Duration: 2020–2021
Funder: European Space Agency
Partners: Gisat s.r.o

Grazing detection from Copernicus data for agricultural subsidy checks is a project carried out in collaboration with the European Space Agency (ESA) and with our partner, Czech EO company Gisat s.r.o. The project started in October 2020 and will finish in November 2021. The aim is to develop a complete satellite-based grassland monitoring service, where grazing detection is equally needed alongside mowing detection and reducing the need for field surveys.
 
Grazing detection service is urgently needed for the monitoring approach reform of the Common Agricultural Policy (CAP). With the reform, the current method of on the spot checks (OTSC) will be gradually replaced with satellite monitoring. One of the most common requirements under CAP that needs to be checked is grassland maintenance, which can be performed by either mowing or grazing. To provide a complete satellite-based grassland monitoring service, grazing detection is equally needed alongside mowing detection. Without the grazing detection, complete grassland maintenance checks cannot be performed with satellite monitoring, as a significant part (~20%) of the European grasslands are being grazed.

Our aim is to develop a grazing detection methodology based on Copernicus data (Sentinel-1 and Sentinel-2 imagery time series). We are planning to test the methodology with selected European national paying agencies (NPAs) and further aim is prototype development for public sector applications.

Planned outcomes:

  • Develop grazing detection methodology based on Copernicus data (Sentinel-1 and Sentinel-2 imagery time series).

  • Provide the NPA operators means to carry out checks on grasslands using EO data and substituting on the spot checks of grassland grazing activity with new EO data based grazing detection methodology.

  • Close the grasslands subsidy checks case for CAP satellite monitoring.


The timeline of the project is presented in the table below.
