The objective of this technical report is to describe in details the hypotheses about de future of the various drivers as well as the general rules adopted for translating them into quantitative hypotheses readily processible by the GlobAgri-AgT model. In the following, we describe successively each driver, the general rules adopted for translating its alternative development patterns into quantitative hypotheses, and the consequences of these general rules on concerned entry variables of the GlobAgri-AgT model. The latter is presented in appendix, pointing out its entry variables.
