Roles of global land use/cover studies in global environmental issues are summarized.Major research results and trends are reviewed from the following viewpoints:
1) estimatiion of environmentalimpacts due to changes in land use and cover.
2) assessment of terrestrial environmental resources.
3) development of landuse models for forecasting environmental impacts and for policy evaluation and.
4) development of land use/cover data on the global scale and a computer environment to support global land use studies.
There have not been reported an enough numbers of researches on development of land use models at the continental and global scale and needs for further intensive studies are identified. It is very necessary to develop databases of land use/cover data which allow time-series analysis.
