| Outline of Final Research Achievements |
This research aims to establish sustainable crop production system in mountainous areas and rejuvenate abandoned satoyama forests by traditional swidden cultivation, which is environmentally sustainable agriculture in intermediate and mountainous areas of Japan. This study revealed that traditional skills and knowledge inherited from Japanese swidden cultivation have been developed not to maximize crop yield but to minimize the risk from various environmental fluctuation. Results of this study showed that better quality of turnips can be produced by swidden cultivation and burning stimulates the germination of turnips. Vegetation survey in fallow forest suggested that degraded satoyama forest can be rejuvenated by slash-and-burn. From these results, four types of forest-agriculture rotation models were established for the restoration of degraded satoyama forests.
