Promoting Value Chains Impacts through Sedentary Based-Cropping Systems

Traditional cropping systems (shifting cultivation and slash-and-burn) contribute to the deforestation, land degradation and low agricultural productivity. Alternative systems emerge with combined efforts of smallholder farmers and researchers in the Sudan-Guinean zone of Benin. The study promotes value chains (sedentary-based cropping production settled marketing through the storage and processing) and impacts. Results show Increase of cropping systems productivity (healthy seeds yam production by minisetts technique, 10 t - 33 t/ha yam yield fresh matter, return on investment (20-60 %), tubers storage for at least 7 months, tuber processing into pounded yam improved varieties of yam with good organoleptic quality, tuber processing with mechanical slicer in dried tubers (chips without aflatoxine attacks) with social and environment impacts.
