Assessment of Agricultural Practices From Sentinel 1 and 2 Images Applied on Rice Fields to Develop a Farm Typology in the Camargue Region

Abstract: In the global change context, an efficient management of the available resources has become one of the most important topics particularly for sustainable crop development. Many questions concern the evolution of the rice farming systems in Camargue in Southeastern France, which play a crucial role in controlling the soil salinity. Their surface area significantly decreased from 20, 000 ha in 2010 to 14000 ha in 2014. The arrival of the new Sentinel satellites makes it possible to evaluate these crop evolutions… Show more

“…The global accuracy of the land use map was 88% of wellclassified crops (rice, wheat, and grassland) and 99% for the rice class, which was quite satisfactory. Details on the statistical scores can be found in Courault et al (2020). Rice and wheat can be easily distinguished because their cultural cycles are staggered in time (wheat being sown in winter and harvested at the end of July and rice being sown in April and harvested in autumn).…”

“…The solar and sensor angles are necessary for computation. The normalized difference vegetation index (NDVI) was also computed for each image to extract the sowing date according to the method described in Courault et al (2020) (a brief summary is given in Supplementary Material part 3).…”

“…Thus increasing the difficulty to assess the spatial variability of the agricultural practices through field surveys, which is also costly and time-consuming. Sometimes, the only available information comes from farmers' declarations (Courault et al, 2020). With the rapid development of geospatial technology in the last years, the acquisition of high-quality spatial and temporal data has become cost-effective and efficient, offering opportunities for land monitoring and management.…”
