Surface water availability was based on distance to perennial waterbodies (DPW) and stream order weighted distance to water (drainage) (SWD). Distance to perennial waterbodies was derived from both monthly Sentinel surface water and Landsat surface water. Sentinel water detection was performed in Google Earth Engine by applying a water detection index and threshold (Ricardo et al. pers. comm.) to monthly median pixel reflectance values. Monthly binary water masks were summed for all 48 months from 1 January 2016 to 1 January 2020. Pixels were assigned a value of one (water) where water was detected for more than 24 months (>50% detection rate).
