  • Settlement and changing land use in the Chitwan district of Nepal
  • This paper focuses on how population growth and the process of continued migration from the Hill Region and settlement in the Terai Region of Nepal result in considerable changes in land use and fragmentation of land-holdings. It is argued

  • Population and land use changes in the central highland Province of Dak Lak, Vietnam
  • resource database, a classification of the land use changes in the period 1979-1989 and 1994 was conducted using air photos and satellite images. Finally the land use change was analysed using a geographical information system. The produced maps create
