Symposium at the Salon International de l'Agriculture 2015: soils

The 68th United Nations General Assembly declared 2015 as the International Year of Soils.  INRA thus devoted its symposium at the Salon International de l’Agriculture to "Soils: their services and uses".

The symposium was broadcast via direct video streaming and a live debate on this web page and via @Inra_France and @Inra_Intl with the hashtag #IYS2015.

The first part of the symposium was devoted to research findings regarding:

  • the variability of soils, with particular focus on their biological component, which is a particularly active area of research at present,
  • the services rendered by soils, notably relative to climate regulation and their role in the control of climate change, 
  • the management of soils through farming practices, with a view to optimising the different ecosystem services anticipated from them.

The importance of the services rendered by soils means that a wide variety of actors may expect benefits from them, although their viewpoints and interests may sometimes, or even frequently, diverge.  The second part of the symposium will be devoted to different uses of soils and the conflicts associated with them, and the effects these may have on the French land market on the one hand, and global food security on the other.

After each part of the event, experts responded to presentations of the work carried out by INRA research scientists and their partners, as a trigger for subsequent debate with the audience.
