description: Sediment Retention for Water Quality Regulation  expressed as sediment
  retention on natural and seminatural pixels multiplied by the number of people downstream
  of those pixels at a resolution of 10 arc-sec (~300 m). Sediment retention provided
  by vegetation was modelled by adapting the InVEST Sediment Delivery Ratio (SDR)
  model, which maps overland sediment generation and delivery to the stream. Ideally
  this would be delineated for reservoirs, irrigation canals, or other water delivery
  infrastructure that is most impacted by sedimentation, but lacking a comprehensive
  global dataset identifying all such infrastructure, we again use the proxy of number
  of people downstream. For more information on this layer, including detailed methods,
  please see the lineage section of the accompanying metadata YAML file and/or visit
