Global future land use forecast dataset FROM-GLCSimulation4.5 includes 30m land use forecast data under global future climate change scenario RCP4.5. The land cover types mainly include 9 primary types. With the proposal of the post-2015 sustainable development goal of the United Nations, more and more countries and scholars need to understand the future scenarios of land use change in order to rationally plan and use land resources. Detailed future land use data are also important basic data for studying global climate and environmental change. This dataset simulates the land use situation with higher resolution under the future climate change scenario RCP4.5. The land use change data with higher resolution is of great significance in supporting the understanding of the interaction and response between human activities and the ecological environment. It provides higher resolution simulated future land use and change data for sustainable development of global scientific research.
