This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes.

People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be des...

Description
A National Research Council committee will review the present status of spatially explicit land-change modeling approaches and describe future data and research needs so that model outputs can better assist the science, policy, and decision-support communities. Future needs for higher resolution and more accurate projections will require improved coupling of land-change models to climate, ecology, biogeochemistry, biogeophysical, and socioeconomic models; improved data inputs; improved validation of land-change models; and improved estimates of uncertainty associated with model outputs. The study will provide guidance on the verification strategies and data, and research requirements needed to enhance the next generation of models. In particular, the study committee will:
- Assess the analytical capabilities and science and/or policy applications of existing and emerging modeling approaches.
- Describe the theoretical and empirical basis and the major technical, research, and data development challenges associated with each modeling approach.
- Describe opportunities for improved integration of observation strategies (including ground-based survey, satellite, and remote sensing data) with land-change modeling to improve land-change model outputs to better fulfill scientific and decision making requirements.
