- 요약Land Use and Land Cover Change (LULCC) is a vital process in the coupled human-Earth system, significantly impacting ecological, climate, and socioeconomic processes. Over the past six decades, one-third of global land has changed due to human activities and environmental-related factors. These changes are expected to continue under future scenarios, making reliable LULCC projections essential for understanding climate change and informing mitigation strategies. Integrated Assessment Models (IAMs), which represent multiple human system interactions, are widely used to project LULCC at both regional and global levels. Despite advances in IAMs such as the Global Change Analysis Model (GCAM), the impacts of dynamic forest carbon change-driven jointly by forest management and environmental change-remain underrepresented, leading to biases in LULCC projections. This dissertation addresses these gaps by quantifying the individual, combined, and interactive effects of forest management and environmental change on forest carbon dynamics and LULCC projections. It also explores uncertainty introduced by LULCC spatial downscaling methods, which are critical for generating gridded inputs from region-level IAM output for downstream applications such as the carbon flux estimation through Earth System Models (ESMs). In the first chapter, I investigate the impact of forest management-induced yield (measured in m³/ha, representing the aboveground component of forest carbon in managed forests) changes on future LULCCs across five Shared Socioeconomic Pathways (SSPs). By soft-linking the Global Timber Model (GTM) with GCAM, I find that future increases in forest management intensity generally lead to increased forest yield, which in turn results in an overall reduction in the area undergoing land use change and notable reductions in managed forests. In the second chapter, I explore the role of environment-driven forest carbon change in shaping future LULCC. I incorporate the impacts of environmental change on forest carbon-derived from a Dynamic Global Vegetation Models (DGVM) under three combinations of Shared Socioeconomics and Representative Concentration Pathways (SSP-RCP) scenarios into GCAM. Considering forest carbon change decreases the projected expansion of managed forests and managed pastures, and frees up more area for unmanaged pastures, unmanaged forests, and cropland. In the third chapter, I investigate the combined, individual, and interactive effects of forest management and environmental change on the spatio-temporal dynamics of forest carbon and the resulting LULCC projections under two SSP-RCP scenarios, using GTM, GCAM, and DGVM simulations. I find the combined effects can lead to 31.6±7.7% (mean±sd) and 54.8±6.3% increases in forest carbon and a 4.0±0.6% and 13.2±1.4% relative increase in natural land globally under SSP126 and SSP585, respectively. In the fourth chapter, I assess the uncertainties introduced by spatial downscaling converting IAM-derived regional LULCC into gridded patterns, and their impacts on terrestrial carbon fluxes in the Arctic-Boreal Vulnerability Experiment domain. I find differences across spatial downscaling methods contribute more than 79% of the LULCC-driven variation in carbon cycle projections by 2100. By incorporating forest carbon dynamics into LULCC projections and addressing spatial downscaling uncertainty, this dissertation fills a critical gap in LULCC modeling and quantifies an unavoidable source of uncertainty in gridded LULCC generation. Together, these contributions enable more realistic LULCC projections and provide a better foundation for future studies examining the wide-ranging impacts of LULCC.
