Dear Giotto. Are you thinking about promoting crop wild relatives for specific species? Or rather in general? It might be worth having a look at the work done by Charlotte Watteyn in the context of vanilla agroforestry systems with crop wild relatives in Costa Rica. See . https://www.sciencedirect.com/science/article/abs/pii/S1161030123001582. One of the aspects she explored, was the possibility to grow vanilla CWR as a “crop” within existing cocoa plantations, hence developing some kind of agroforestry system. The results were promising and the approach was a good way of creating a buffer system which might be an alternative for (or complementary system to) intensive plantations of domesticated Vanilla on the one hand, without risking overharvesting of CWR in pristine forest on the other hand.
