Why this data
Free global products (Hansen, ESA WorldCover, ESA CCI Biomass) apply generic thresholds that underestimate forest cover by about 40% in sparse-canopy areas, and never distinguish species. These layers are calibrated specifically for this region from Sentinel-1/2 imagery and GEDI LIDAR data, with species-level discrimination (no global product offers this), and validated against independent sources: +4.3% difference from SIREDD (ANEF) for broadleaf cover, -2.7% difference from ESA CCI Biomass 2022 for biomass density. Full methodology documented, known limitations stated explicitly.
Layers
Automated satellite detection (3 VIIRS satellites, about 6 passes a day over Morocco), not verified on the ground. A hotspot can be agricultural burning, an industrial heat source, or a forest fire: the satellite cannot tell them apart. 3-day window.

Future climate scenarios
Projection to the 2041-2060 horizon (4-model CMIP6 ensemble mean, NEX-GDDP-CMIP6), compared to a recent 1995-2014 reference. This is not a prediction: it is a range across two possible emission pathways. The De Martonne aridity index (precipitation and temperature only) is a different indicator from the water deficit shown on the map above, not its future version: this climate product does not provide evapotranspiration data.
| Period | Precipitation | Average temperature | De Martonne index |
|---|---|---|---|
| Reference 1995-2014 | 483 mm/yr | 17.1°C | 17.9 |
| Moderate (SSP2-4.5), 2041-2060 | 459 mm/yr (-5.0%) | 18.9°C (+1.76°C) | 16.0 (-10.7%) |
| Pessimistic (SSP5-8.5), 2041-2060 | 439 mm/yr (-9.3%) | 19.5°C (+2.37°C) | 15.0 (-16.5%) |
Limits to keep in mind
SSP2-4.5 is labelled "moderate", not "optimistic": a genuine strong-mitigation scenario (SSP1-2.6) does not exist in this dataset. The ensemble only includes 4 models (not the dozens available in the full CMIP6 archive), so the true uncertainty range is likely wider than what is measured here. ~25 km resolution: does not capture the local relief nuances that the current water-stress layer captures better for present conditions.
