Cultivated areas

The agricultural and forestry sectors must reconcile socio-economic production issues with major environmental issues related to reducing the ecological impacts of these activities. In this context, the Cassia® approach makes it possible in particular to:

MAPPING OF HEDGEROWS IN A BOCAGE CONTEXT

Hedgerows are an essential part of the agricultural landscape. They make a major contribution to the biodiversity of agro-ecosystems and also provide numerous ecological services (habitat for growing aids, regulation of soil erosion, etc.).
In the example presented down below, the Cassia® approach has made it possible to precisely map hedgerows in order to create a functional typology linked to other landscape elements (forests, fields, buildings, etc.).

STUDY OF CULTIVATED AREAS

Within the framework of the ambitious cultural and tourist development project of AlUla Region (KSA), Valorhiz has been commissioned by the French Agency for the Development of AlUla (AFALULA) to map, characterise and quantify the cultivated areas throughout the County of AlUla. By combining field missions and the innovative Cassia® approach, nearly 15,000ha of cultivated land and associated soils have been mapped and characterised with a very high level of accuracy. These data now serve as the basis for building the County’s agricultural development strategy. The example on the right illustrates the application of Cassia® technology for the detection of different types of soil and crops in this region. This mission has been carried out on behalf of the Agence Française pour le Développement d’AlUla (AFALULA) in partnership with the Royal Commission for AlUla (RCU).
