The FAO may want to work with the regenerative agriculture alliance https://www.regenagalliance.org/ . This organization is focused on scaling up systems-level regenerative poultry solutions that restores ecological balance, produces nourishing food, and puts money back into the hands of farmers and food chain workers. In particular they are focused on raising poultry and hazelnuts in degraded lands in the US Midwest. Perhaps the FAO could identify what crops should be raised with free range poultry in degraded lands where the FAO has major projects
