Solar parks could support insect pollinators in present day landscapes if located and managed appropriately. However, the role of solar parks under future land use change has not been explored. We use a GIS and pollinator model to predict bumble bee density inside solar parks and surrounding landscapes to address this knowledge gap and as part of this, require present day and future landcover maps of Great Britain. However, available future land use maps are coarser spatial resolution and include fewer categories than present day landcover maps. We therefore present the challenge of downscaling coarse resolution future maps for use with a pollinator model, using resampling and conditional overlay approaches
