Micronesia Forest Area

The forest area indicator measures the total extent of land covered by forests, defined by the Food and Agriculture Organization (FAO) as land spanning more than 0.005 km² (0.0019 sq mi) with trees higher than 5 m (16 ft) and a canopy cover of more than 10%. This definition requires that the land is not primarily under agricultural or urban use. It includes both naturally regenerating forests and planted forests, such as timber plantations established for wood production. However, it specifically excludes fruit tree plantations, oil palm segments, and agroforestry systems where crops are grown beneath a tree canopy. The indicator accounts for areas that are temporarily unstocked—due to harvesting or natural disturbances—provided they are expected to regenerate. It serves as a fundamental metric for assessing global biodiversity, carbon sequestration capacity, and the efficacy of environmental conservation policies at both national and international levels.

Data collection is coordinated primarily by the Food and Agriculture Organization (FAO) through the Global Forest Resources Assessment (FRA). This process relies on a combination of national forest inventories provided by member states and remote sensing analysis. National reports are prepared by official correspondents using ground-based surveys, though the frequency of these updates varies by country. To ensure global consistency, the FAO uses satellite imagery to verify reported figures and fill data gaps. A major limitation is the variation in data quality; while some nations provide updates every few years, others may rely on surveys conducted over 10 years ago. Additionally, differences between land-use definitions and land-cover data can lead to conflicting estimates between international monitoring platforms, as intended use and physical tree presence are distinct metrics.

While the FAO remains the primary source for official land-use data, Global Forest Watch (GFW) provides annual tree-cover estimates based purely on satellite observations. GFW often reports higher loss figures because it includes temporary removals like harvesting that the FAO classifies as still being forest if the land is intended to regrow.

A global benchmark for healthy terrestrial ecosystems is approximately 31% of total land area. Annual net forest change is considered positive if gains from afforestation and natural expansion exceed losses from deforestation, though the preservation of primary forest is the highest priority for biodiversity.

Current estimates indicate that the world has a total forest area of approximately 41 million km² (16 million sq mi), covering about 31% of the global land area. While the world continues to lose forest area, the rate of net loss has slowed considerably over the last few decades. Recent data shows the annual net loss fell from 78,000 km² (30,116 sq mi) in the 1990s to approximately 47,000 km² (18,147 sq mi) in the most recent decade. This trend is driven by a combination of reduced deforestation in certain tropical nations and significant increases in forest area in temperate regions through both natural expansion and large-scale planting initiatives. Despite this slowing rate, the loss of primary tropical forests remains a critical concern, as these ecosystems are irreplaceable for carbon storage and biodiversity.

Forest distribution is highly uneven, with just five countries—Russia, Brazil, Canada, the United States, and China—containing 54% of the world's total forest area. Europe, including Russia, holds the largest regional share at 25%, while South America has the highest proportion of forest cover relative to its land area at 49%. Over the last 30 years, regional trends have diverged sharply: Africa and South America have experienced the largest net losses of forest area due to agricultural expansion and logging. Conversely, Asia has seen significant net gains, largely driven by massive reforestation programs in China. High-income countries generally show stable or increasing forest areas, while low-income tropical regions continue to face the highest pressures from land-use conversion for cattle ranching and soy production.
