Taiwan land cover data LUH2 SSPs

This new version updates the LU map of Taiwan, downscaled from the LUH2 SSPs dataset, for the years 2016 to 2099 at a spatail resolution of 500 m by 500 m. Taiwan is defined within the LUH2 dataset boundaries, ranging from 120° to 122°E and 21.5° to 25.5°N. The dataset includes five scenarios: SSP1 with low challenges from adaptation and mitigation; SSP2 with intermediate challenges; SSP3 with high challenges; SSP4 where adaptation challenges dominate; and SSP5 where mitigation challenges dominate.

The future land-use share was directly extracted from the LUH2 dataset at a spatial resolution of 25 km x 25 km. To downscale this information for Taiwan, a long-term land-use change/transition probability map is required as a reference to allocate future land types from coarse to fine spatial resolution. In this study, we applied the long-term land-use change/transition probability map derived from the (potential land-use change, PLC) method. The spatial allocation algorithm integrates PLC maps from historical LULCC reconstructions with gross change information from future land-use maps based on the LUH2 dataset.

For a detailed description of the downscaling approach, please refer to the study "Navigating Land-Use Trends: Bridging Present Realities and Future Projections in Taiwan" by Chen et al. (in submission).
