• The aim of this paper is to clarify the significance of collective land management and collective water use in the dune land agriculture. Collective land use in this paper has such a characteristic that the control of land use to establish the rotation system including cleaning crops is combined with centralization of the land use rights to the farm households engaging in the dune land agriculture. It aims mainly to avoid the defects caused by continuous cropping.These defects derive from the contradiction of monoculture and obstruct the stable reproduction of agricultural management, as observed in many cases of commercial upland farming like the dune land agriculture. Therefore, the change to rotation farming becomes necessary. When the farm size is not expanded, agricultural income declines because of the low prices of the other crops which are combined with the main crop. It is difficult that each of small-scale households adopts rotation system and expands its farm size at the same time. Collective land management sugggests the way to remove this difficulty.By the way, an intensive land use in upland farming requires the irrigation facilities. Farm households who operate the lease farmland can pay the initial cost of it because of the stability of the landlease based on the collective land management. On the contrary, collective water use forms the foundation of collective land management by standardization of land rent level.
