Extrapolation domain analysis (EDA) is a methodology for identifying geographical areas that seem suitable for adoption of innovative ecosystem management practices on the basis of sites exhibiting similarity in conditions such as climatic, land use and socioeconomic indicators.
[1] The research has stimulated members of several of the Challenge Program for Water and Food projects to explore potential areas for scaling out.
[4] The method developed further the research around Jones' 'Homologue' analysis[5][6] by incorporating socio-economic variables in the search for similar sites around the Tropics.
[1] 'Homologue' was developed to determine the similarity of climatic conditions across a geographical area to those exhibited by the pilot site; the pixel resolution at which this is processed is 2.43 arc minutes, or 4.5 km at the equator.
[7][8] In essence, statistical inference is based on determining the probability of target sites adopting the change demonstrated in pilot areas.
