Extrapolation domain analysis (EDA) is a methodology for identifying geographical areas that are suitable for adoption of innovative practices of ecosystem management on the basis of selecting sites that have similar climate, land-use and socio-economic indicators.

This working paper presents detailed steps how to implement an EDA. For a particular research project, it starts with establishing a baseline assessment of the project, and proceeds through data collection, preparation, and similarity modeling concluding with reporting and validation. The guide is designed for users with intermediate knowledge of GIS and Bayesian statistics for a smooth and easy implementation of the method. It also requires the participation of the members of the research project for proper identification of key variables to be used in the process.
