  "title": "Sustainable Landscape Efficiency Frontiers \u2014 Input Layers (Polasky et al. 2026)",
  "description": "H3-hexed input layers for the sustainable landscape efficiency frontier analysis of Polasky et al. (2026, Science). Economic production-value layers (crop, oil palm, grazing revenue; grazing methane) are native **H3 resolution 5** (from 5-arcmin ~9 km source); forestry, Forest Landscape Integrity, and land-use transition costs are native **resolution 8** (from 300 m source); all carry an h5 parent column for a common res-5 decision unit (~8000 ha, the paper's parcel). Revenue/methane/FLII are per-ha/index DENSITIES (mean reducer \u2014 aggregate with AVG, never SUM); transition costs are per-cell USD TOTALS (sum reducer). Sourced from the CC0 Dryad deposit (doi:10.5061/dryad.qjq2bvqw5); see also iucn-richness-2025, wwf-ecoregions-2017, irrecoverable-carbon for the biodiversity and carbon objectives, and wdpa for the IUCN I\u2013IV constraint. Also included are the scenario-construction constraint masks (binary suitability/slope eligibility, mode reducer, res 8) that restrict admissible land-use alternatives per parcel, and the carbon-zone ID raster (mode reducer, res 8) that keys the Spawn et al. carbon_table for graded per-land-use carbon.",
