Application of remote sensing techniques to discriminate between conventional and organic vineyards in the Loire Valley, France

Remote sensing techniques can effectively differentiate between conventional and organic vineyards, achieving a 91.4% success rate in identifying both viticultural methods and grape varieties in the Loire Valley. The study analyzed ASTER satellite imagery, focusing on spectral reflectance patterns influenced by chemical treatments and inter-row vegetation. Key findings indicate that conventional vineyards exhibit distinct spectral signatures, particularly in short-wave infrared bands, due to chemical impacts on leaf composition and structure. Organic vineyards, lacking these treatments, show different reflectance characteristics, highlighting the potential of remote sensing as an early indicator for viticultural monitoring. This approach offers a non-invasive method to assess agricultural practices, complementing field inspections or laboratory analyses.
