This paper describes how the people utilize the diversified natural resources for their living and form subsistence activities connected with seasonal change. The connection of subsistence activities as well as land use and habitat is also focused on. Various subsistence activities and land use in the wetland of Lao PDR are characterized by rice farming and paddy fields. The village and land use are formed on the basis of rice cultivation. The paddy fields and their surroundings are regarded as the ecotone where creatures live in dependence on the environment in which rice growing takes place. With rice, water, trees, and wild animals and plants, the paddies in our research area have complex ecological characteristics.
