FoodWeb for Agroecology

A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological community.

Ecosystems are increasingly manipulated for agricultural goals. Food web structures of agrosystems highly influence their agronomical performance and stability. Although it has been observed that living communities are ruling the performance of agroecosystems, these
living communities are generally ignored by agronomists who focused mainly on abiotic factors. Indeed, agronomists usually focus on the soil–plant–atmosphere continuum. Now, ecological modellers can link food web models with soil–plant models to create innovative frameworks. Here, we advocate that foodwebs must be included in simulations of production and in studies of emerging properties. We emphasize the role of trophic chains in the regulation of pests.

Agroecology (a-grō-ē-ˈkä-lə-jē) is the study of ecological processes applied to agricultural production systems. Bringing ecological principles to bear can suggest new management approaches in agroecosystems.

A graph database (GDB) is a database that uses graph structures for semantic queries with nodes, edges, and properties to represent and store data. A key concept of the system is the graph (or edge or relationship). The graph relates the data items in the store to a collection of nodes and edges, the edges representing the relationships between the nodes.

Autour de l'enquête en 2019 du NY Times sur la PAC (Politique Agricole Commune)
  • > "corrélation nette entre les exploitations les plus polluantes et celles qui bénéficient le plus des aides de la PAC"
  • > nécessité d'une "triple conditionnalité des aides (environnementale, sociale et de bien-être animal)"
