Land Use Evolution and Impact Assessment Model
[ Get Service ]
[ Update this Record ]

Abstract: The Land Use Evolution and Impact Assessment Model (LEAM) is a computer-based tool that simulates land-use changes across space and time. LEAM urban land-use transformation modeling begins with drivers, those forces (typically human) that contribute to land-use change. Model drivers represent the dynamic interactions between the urban system and the surrounding landscape. Each driver is developed as a contextually independent sub-model which allows for calibration before being run simultaneously in the LEAM model. Environmental, economic and social system impacts of alternative scenarios such as different land-use policies, growth trends, and unexpected events can be tested out in the LEAM modeling environment. Scenario results and impact assessments can be displayed in a number of ways: as simulation movies, through a built-in mapping tool, in graph or chart displays, or simply as raw data. LEAM's visual representation of each scenario's outcome provides an intuitive means of understanding the potential of decisions and acts as a catalyst for discussion and communal decision-making.

All driver models figure into creating the development probability model, while the impact models respond to the land use change that is triggered by the development probability model. Impacts assessed by the LEAM model are also used in the creation of sustainable indices and indicators that can feed back into the model drivers for new policy formation.
