From rasters to gradients of a social ecological research network
Résumé
Open, world wide, geographical information databases are frequently mobilized for hydrological studies in poorly gauged watersheds. More generally, the variety of such databases-landscape, climate, population, vegetation, land cover, practices and so forth-is an opportunity for sharing insights amongst a social ecological research network or a federation of protected areas. In practice, dealing with the heterogeneity in the variables, in the datasets and in the providers, remains a challenge as it often raises some of well-known interoperability and reuse issues. Through software engineering, some general workflow is set up from raster extraction to the computation of social and ecological indicators. The heterogeneity in the data allows for a reflection on FAIR practices amongst a number of providers on the one hand, and the fairification of the products of this research in the other hand. As a case study, the workflow is operated on the French long term socio-ecological research network, namely Réseau des Zones Ateliers, the nodes of which conduct action-oriented studies on social ecological systems (SESs) such as river basins, rural, urban or mountainous territories, or protected areas in Metropolitan France and outside Europe. As expected, some gradients reflecting the diversity in the territories already appear in a half-page pie chart table representing computed indicators.
