Adaptation to the climate change: Interest of a prospective approach / Adaptation au changement climatique : l'intérêt d'une démarche prospective

The current challenges of the agronomic research and in particular the adaptation of agriculture to climate change, require a very broad disciplinary mobilization. To meet these challenges, which go beyond its disciplinary and territorial organization, the INRA initiated a new system of interdisciplinary piloting of research. Thus, the métaprogramme ACCAF is trying to understand the joint effects of the various modifications caused by climate change on terrestrial farming and natural environments, and to define adaptation strategies of adaptation as well as their environmental and socio-economic consequences. Within this framework, twenty-three research laboratories have been collaborating in the project LACCAVE and united their efforts in the project LACCAVE in order to examine the effects of climate change on the vine and wine sector. In addition to six disciplinary working groups, this project is made up of an interdisciplinary group including researchers and experts of public institution working with the sector, which has carried out a foresight exercise. By directing the reflection towards a medium-long term future (2030–2050), this prospective exercise authorizes us to leave the temporal horizon of the negotiation and the dictatorship of emergency. As the long-term future is neither known nor recognizable, the evolutions are considered as combinations of assumptions expressed in one potential form and its opposite. For the prospective in the LACCAVE program, four strategies of adaptation of viticulture for 2030–2050 were predefined and a collective and pluridisciplinary work made possible the writing of a plausible way of events leading to each strategy. These results will then be used to debate with the actors of the wine sector at various geographical levels, in order to contribute to the development and the consolidation of choices of strategies of adaptation of the vineyards to climate change. The presentation will focus on this original methodology and its specific implementation. Stories are detailed in another article “Work of prospective on the adaptation of the viticulture to climate change: which series of events could support various adaptation strategies?”
