Land Use and Climate Change Team
Science Center Objects
We are a research team focusing on understanding the rates, causes, and consequences of land change across a range of geographic and temporal scales. Our emphasis is on developing alternative future projections and quantifying the impact on environmental systems, in particular, the role of land-use change on ecosystem carbon dynamics.
We are interested in how land-use and climate systems will evolve and interact to shape future land-use and carbon dynamics. Our team is developing the Land Use and Carbon Scenario Simulator (LUCAS) model. LUCAS is a state-and-transition simulation model designed to track changes in land use, land cover, land management, and disturbance, and their impacts on ecosystem carbon storage and flux.

Date published: June 22, 2017Status: ActiveLand use and tsunami hazards in the Pacific Northwest
Tsunamis have the potential to cause considerable damage to communities along the U.S. Pacific Northwest coastline. As coastal communities expand over time, the potential societal impact of tsunami inundation changes.
To understand how community exposure to tsunami hazards may change in coming decades, we projected future development (i.e. urban, residential, and rural), households, and...

Date published: June 22, 2017Status: ActiveCalifornia land-change projections
This dataset consists of modeled projections of land use and land cover and population for the State of California for the period 1970-2101. For the 1970-2001 period, we used the USGS's LUCAS model to "backcast" LULC, beginning with the 2001 initial conditions and ending with 1970. For future projections, the model was initialized in 2001 and run forward on an annual time step to 2100. In...

Date published: June 22, 2017Status: ActiveLand change and water use in Mediterranean California
Water shortages in California are a growing concern amidst ongoing drought, earlier spring snowmelt, projected future climate warming, and currently mandated water-use restrictions. Increases in population and land use in coming decades will place additional pressure on already limited available water supplies.
We used a state-and-transition simulation model to project future changes in...

Date published: June 22, 2017Status: ActiveThreats to protected areas
Land-use intensification poses significant threats to biodiversity both directly through the alteration and fragmentation of ecosystems and habitat loss, and indirectly through the disruption of supporting ecological processes. While protected areas offer refugia for species and ecosystems, they do not function in isolation from surrounding natural, working, or human-dominated landscapes....

Date published: June 22, 2017Status: ActiveLand use and carbon modeling in the Sierra Nevada Mountains
The goal of this study was to develop an integrated, regional-scale terrestrial carbon model, which can project changes in ecosystem carbon dynamics resulting from both changing biophysical conditions (e.g. CO2 fertilization, changes in climate) and land-change processes (e.g. urbanization, agricultural intensification, wildfire, harvest).
Our objective was to develop a modeling...

A major scientific challenge in global change research is connecting coarse-scale global assessments, particularly those involving the projection of land use, to scales relevant and useful for analysis and management. We have downscaled land use projections from two global scenario frameworks, the Special Report on Emission Scenarios (SRES), and the Representative Concentration Pathways (RCPs...

Year Published: 2018Effects of contemporary land-use and land-cover change on the carbon balance of terrestrial ecosystems in the United States
Changes in land use and land cover (LULC) can have profound effects on terrestrial carbon dynamics, yet their effects on the global carbon budget remain uncertain. While land change impacts on ecosystem carbon dynamics have been the focus of numerous studies, few efforts have been based on observational data incorporating multiple ecosystem types...

State-and-transition simulation models (STSMs) provide a general framework for forecasting landscape dynamics, including projections of both vegetation and land-use/land-cover (LULC) change. The STSM method divides a landscape into spatially-referenced cells and then simulates the state of each cell forward in time, as a discrete-time stochastic...

Changes in land use and land cover (LULC) have important and fundamental interactions with the global climate system. Top-down global scale projections of land use change have been an important component of climate change research; however, their utility at local to regional scales is often limited. The goal of this study was to develop an...

Global land-use/land-cover (LULC) change projections and historical datasets are typically available at coarse grid resolutions and are often incompatible with modeling applications at local to regional scales. The difficulty of downscaling and reapportioning global gridded LULC change projections to regional boundaries is a barrier to the use of...
