A statistical methodology to downscale aggregated land use data

• Scenario and past Land Use (LU) data often at coarse resolution reflecting global scale processes acting over large areas • Fine resolution LU data is needed for ecological studies (e.g. population dynamics, biodiversity, carbon stocks...) • In particular, there is a need for a fine resolution LU model over a large extent (the Svalbard migratory geese flyway) to model bird population dynamics Downscaling – how?
