Monitoring the world's forests
FAO has been monitoring the world’s forests since 1946 through regular assessments conducted with its member countries. FAO now works with partners to use remote sensing and cloud-based super computers to help countries monitor and report on forests and develop climate change mitigation plans and data-driven land-use policies. The Global Forest Resources Assessment presents a comprehensive view of the world’s forests and the ways in which the extent of forest resources, their condition, management and use is changing.
FAO also compiles global statistics on the production and consumption of forest products, pulp and paper production capacities and recovered paper data surveys. The FAO Yearbook of Forest Products is a compilation of statistical data on basic forest products for all countries and territories of the world.
At a national level, FAO also supports countries to develop national forest monitoring systems, forest product statistics and socioeconomic surveys to improve national forest information.

Regional assessment of above-ground biomass using field, airborne light detection and ranging and satellite data integration
2025
Tropical forests are key to the global carbon balance but face serious threats from deforestation and degradation. Accurate estimates of above-ground biomass density are crucial for forest monitoring, climate reporting and initiatives like REDD+.
Global Forest Resources Assessment 2025
2025
FAO completed its first assessment of the world’s forest resources in 1948. Since then, the Global Forest Resources Assessment has evolved into a comprehensive evaluation of forest resources and their condition, management and uses, covering all the thematic elements of sustainable forest management. This, the latest of these assessments, examines the status of, and trends in, forest resources over the period 1990–2025, drawing on the efforts of hundreds of experts worldwide.
The status of Mediterranean forests 2025
2025
Forests and wooded lands cover 28 percent of the Mediterranean region. Forest area within Mediterranean countries grew by 12 percent between 1990 and 2020, but gains have slowed and requires enhanced sustainable forest management.
