WHAT THE EVIDENCE SAYS
FAO’s State of the World’s Forests 2026 reports more than 460 million hectares of degraded forest and about 1.56 billion hectares of degraded land globally. It says meeting 2030 goals requires at least 470 million hectares to be brought under restoration and presents pathways that include natural regeneration, agroforestry, hydrologic repair, native vegetation, production-landscape changes and community-led approaches rather than equating restoration with planting alone.
WHY IT MATTERS / OUR READ
The useful signal is architectural: restoration at scale is a portfolio of ecological processes, land uses, institutions and incentives. The report is strongest where it treats hydrology, livelihoods, production, governance and biodiversity as parts of the intervention instead of assuming that adding trees is the outcome.
CAVEATS / UNCERTAINTY
This is a global institutional assessment and synthesis, not a single controlled experiment. Global area estimates depend on definitions and underlying datasets, and the case studies demonstrate approaches rather than providing standardized causal effect sizes across regions.
