FAO launched today the most comprehensive forestry assessment to date in an innovative and easy-to-use digital format.
Available for public viewing, the Global Forest Resources Assessment report (FRA 2020) and its first-ever online interactive dissemination platform contain detailed regional and global analyses for 236 countries and territories.
Users can now consult a comparable and consistent set of more than 60 forest indicators across countries and regions and download the requested data in a non-proprietary digital format. Monitoring of change over time is also possible in parameters such as forest area, management, ownership and use.
The FRA 2020 key findings:
- The world has a total forest area of 4.06 billion hectares, which is about 31 percent of the total land area. Europe, including Russian Federation, accounts for 25 percent of the world’s forest area, followed by South America (21 percent), North and Central America (19 percent), Africa (16 percent), Asia (15 percent) and Oceania (5 percent).
- The global forest area continues to decrease, and the world has lost 178 million hectares of forest since 1990. However, the rate of net forest loss decreased substantially over the period 1990-2020 due to a reduction in deforestation in some countries, plus increases in forest area in others through afforestation and natural expansion of forests.
- Africa has the largest annual rate of net forest loss in 2010-2020, at 3.9 million hectares, followed by South America, at 2.6 million hectares. The highest net gain of forest area in 2010-2020 was found in Asia.
- Since 1990 an estimated 420 million ha of forest has been lost worldwide through deforestation, conversion of forest to other land use such as agriculture. However, the rate of forest loss has declined substantially. In the most recent five-year period (2015-2020), the annual rate of deforestation was estimated at 10 million hectares, down from 12 million hectares in 2010-2015 and 16 million hectares in 1990-2000.
- The area of forest in protected areas has increased by 191 million ha since 1990, and has now reached an estimated 726 million ha (18 percent of the total forest area of reporting countries). In addition, the area of forest under management plans is increasing in all regions – globally, it has increased by 233 million ha since 2000, reaching slightly over two billion hectares in 2020.
- Top ten countries worldwide for average annual net losses of forest area between 2010 and 2020 are: Brazil, Democratic Republic of the Congo, Indonesia, Angola, United Republic of Tanzania, Paraguay, Myanmar, Cambodia, Bolivia (Plurinational State of), Mozambique.
- Top ten countries for average annual net gains in forest area in the same period are: China, Australia, India, Chile, Viet Nam, Turkey, United States of America, France, Italy, Romania.

There are many statistical measures that show how productive the U.S. is. Its economy is the largest in the world and grew at a rate of 4.1 percent last quarter, its fastest pace since 2014. The unemployment rate is near the lowest mark in a half century.
What can be harder to decipher is how Americans use their land to create wealth. The 48 contiguous states alone are a 1.9 billion-acre jigsaw puzzle of cities, farms, forests and pastures that Americans use to feed themselves, power their economy and extract value for business and pleasure.
Using surveys, satellite images and categorizations from various government agencies, the U.S. Department of Agriculture divides the U.S. into six major types of land. The data can’t be pinpointed to a city block—each square on the map represents 250,000 acres of land. But piecing the data together state-by-state can give a general sense of how U.S. land is used.

The world’s natural places are disappearing at a galloping clip, says a new study, released Friday in the journal Science Advances. It suggests that more than 7 percent of Earth’s natural, intact forest landscapes have been lost since 2000 — and these ecosystems may be in danger of disappearing entirely from at least 19 countries in the next 60 years.
These landscapes represent some of “the last portions of the Earth that are not significantly affected by human influence,” said Lars Laestadius, a forest expert, consultant on natural resources policy and co-author of the new study. “As we lose these, we lose something that is bigger than ourselves.”
The study defines “intact forest landscapes” as areas greater than 500 square kilometers, or 193 square miles, containing a mosaic of forests and other associated ecosystems, such as plains or wetlands. The key is that these areas must be undisturbed by human activities — they can’t be fragmented by roads or deforestation or other industrial operations. Once that happens, the ecosystems cease to be considered “intact.” And as the new study indicates, this is happening more and more frequently around the world.
This research examines the impact of forest management regimes, with various degrees of restriction, on forest conservation in a dry deciduous Indian forest landscape. Forest change is mapped using Landsat satellite images from 1977, 1990, 1999, and 2011. The landscape studied has lost 1478 km2 of dense forest cover between 1977 and 2011, with a maximum loss of 1002 km2 of dense forest between 1977 and 1990. The number of protected forest areas has increased, concomitant with an increase in restrictions on forest access and use outside protected areas. Interviews with residents of 20 randomly selected villages indicate that in the absence of alternatives, rather than reducing their dependence on forests, communities appear to shift their use to other, less protected patches of forest. Pressure shifts seem to be taking place as a consequence of increasing protection, from within protected areas to forests outside, leading to the creation of protected but isolated forest islands within a matrix of overall deforestation, and increased conflict between local residents and forest managers. A broader landscape vision for forest management needs to be developed, that involves local communities with forest protection and enables their decision-making on forest management outside strict protected areas.
