Rainfed agriculture (expressed as proportion of land area) in temperate drylands estimated from: (A) remote sensing (e.g. realized abundance), (B) predicted under current conditions from a statistical model (e.g. potential abundance), (C) predicted under future conditions (median GCM, RCP8.5), and (D) change in prevalence between future and current climate.
