List of countries by forest area
View on Wikipedia


This is a list of countries and territories of the world according to the total area covered by forests, based on data published by the Food and Agriculture Organization of the United Nations (FAO). In 2010, the world had 3.92 billion hectares (ha) of tree cover, extending over 30% of its land area.[1][need quotation to verify]
In 2020, the world had a total forest area of 4.06 billion ha, which was 31 percent of the total land area. This area is equivalent to 0.52 ha per person[2] – although forests are not distributed equally among the world's people or geographically. The tropical domain has the largest proportion of the world's forests (45 percent), followed by the boreal, temperate and subtropical domains. More than half (54 percent) of the world's forests is in only five countries – the Russian Federation (20.1%), Brazil (12.2%), Canada (8.6%), the United States of America (7.6%) and China (5.4%).[2]
Many of the world's forests are being damaged and degraded or are disappearing altogether. Their capacity to provide tangible goods, such as fiber, food, and medicines, as well as essential ecological services, including habitat for biodiversity, carbon storage, and moderation of freshwater flows, is under greater threat than ever before.[3] According to World Resource Institute in Washington, between 2000 and 2020 the world lost 101 million hectares (Mha) of tree cover, mostly tropical and subtropical forests (92%).[3] The FAO is compiling a new global assessment due to be published in 2025.[4]

FAO Forest Definition
The Food and Agriculture Organization (FAO) of the United Nations employs a standardized definition of forest for its Global Forest Resources Assessments (FRA), adopted in 2000 to ensure global comparability of data reported by member countries. Under this definition, forest comprises land spanning more than 0.5 hectares, featuring trees with the potential to reach a height of more than 5 meters at maturity and a canopy cover exceeding 10 percent. This includes areas that are temporarily unstocked, such as those recovering from harvesting or natural disturbances, provided they retain the capacity to meet these biophysical thresholds in situ and are not primarily designated for agricultural or urban uses.[2][3] This threshold-based approach emphasizes structural characteristics—tree height potential and canopy density—over land use intent or management practices, distinguishing forest from other categories like other wooded land (OWL), which applies the same area and height criteria but with a canopy cover of 5–10 percent. The exclusion of predominantly agricultural or urban lands aims to delineate natural or semi-natural tree formations from cultivated systems, such as orchards or agroforestry plots, though implementation relies on national reporting, which can introduce variability in interpretation. For instance, the definition accommodates sparse woodlands in arid regions if they meet the criteria, but it has drawn criticism for potentially overestimating forest extent by including degraded or low-density areas that function more as scrubland than productive forests.[2][4] The FAO's definition facilitates consistent cross-country comparisons in FRA reports, such as the 2020 assessment, which estimated global forest area at 4.06 billion hectares using this framework, but it requires countries to map and report data harmonized to these parameters, often via remote sensing validation or ground inventories. Updates in subsequent FRAs, including 2025, retain the core elements while refining reporting on subcategories like naturally regenerated versus planted forests to enhance precision without altering the baseline threshold. This biophysical focus prioritizes empirical measurability over subjective classifications, supporting policy decisions on conservation and sustainable management, though discrepancies arise when national definitions diverge, necessitating FAO adjustments for aggregation.[5][6]Alternative Definitions and Thresholds
Alternative definitions of forest diverge from the FAO's standardized criteria primarily through adjustments to biophysical thresholds such as minimum canopy cover, tree height, and land area, often tailored to national contexts, ecological specificity, or policy goals like carbon accounting or biodiversity assessment. For instance, while the FAO requires at least 10% canopy cover, some frameworks specify 20-30% to distinguish denser forests from open woodlands or savannas, reducing the inclusion of sparse vegetation that may not function ecologically as closed-canopy systems.[7][8] These variations arise because nearly 800 distinct definitions exist globally, with countries adapting thresholds to local biome characteristics; for example, arid regions may lower height requirements below 5 meters to account for stunted trees, whereas temperate zones might raise canopy minima to exclude degraded lands.[9] Minimum land area thresholds also vary, ranging from 0.05 hectares in some national inventories to 1.0 hectare in others, affecting the classification of small patches or fragmented habitats that the FAO's 0.5-hectare cutoff might aggregate or exclude.[7] Alternative metrics beyond canopy and height include basal area, wood volume, or biomass proportions, which prioritize stocking density over visual cover and are used in frameworks like certain IPCC guidelines for land-use change reporting.[10] In the United States, the Forest Inventory and Analysis program employs a definition emphasizing potential stocking levels of at least 10% for trees capable of reaching 5 meters, but integrates land-use exclusions more stringently than the FAO to align with domestic timber and conservation reporting.[11] Such differences lead to discrepancies in reported forest extents; lower thresholds like the FAO's 10% canopy can classify savanna-like ecosystems as forests, potentially inflating global estimates by including areas with limited carbon storage or biodiversity value compared to higher-threshold definitions that emphasize functional forest attributes.[12] For cross-country comparisons, harmonization efforts, such as those proposed by the FAO, suggest flexible ranges (e.g., 10-30% canopy) to accommodate variability while maintaining comparability, though critics argue that biophysical-only criteria overlook land-use dynamics, such as excluding temporarily unstocked areas post-harvest in managed forests.[7][8] National examples include stricter canopy requirements in European Union reporting (often >20%) to focus on productive woodlands, contrasting with broader inclusions in tropical nations where lower thresholds capture regenerating secondary forests.[13] These alternatives underscore the trade-off between global uniformity and context-specific accuracy in forest monitoring.[14]Methods of Data Collection and Validation
National forest inventories (NFIs) form the backbone of forest area data collection, utilizing systematic sampling grids where field crews measure tree attributes such as diameter, height, and species on permanent or temporary plots spaced across forested landscapes, often at densities of 1 plot per 1,000 to 5,000 hectares depending on national protocols.[15] These ground-based measurements are extrapolated to estimate total area using statistical models that account for plot-level variability and sampling errors, with periodic re-measurements enabling trend analysis over 5- to 10-year cycles.[16] Aerial surveys complement ground data in some countries by interpreting stereoscopic photographs or LiDAR scans to delineate forest boundaries and classify cover types, particularly in remote or topographically challenging regions.[17] For global compilations, such as the Food and Agriculture Organization's (FAO) Global Forest Resources Assessment (FRA), countries submit harmonized reports prepared by official national correspondents, drawing from their NFIs or equivalent systems, which FAO then verifies for consistency with standardized definitions like forest as land spanning more than 0.5 hectares with trees taller than 5 meters.[18] Where national submissions are incomplete, outdated, or absent—particularly in developing nations with limited capacity—FAO supplements with remote sensing-derived products, integrating wall-to-wall satellite analyses to fill gaps and ensure comprehensive coverage.[9] Satellite remote sensing has become integral, employing optical sensors on platforms like Landsat (30-meter resolution) or Sentinel-2 (10-meter resolution) to capture multispectral imagery, from which algorithms detect canopy cover through vegetation indices such as NDVI or machine learning classifiers trained on spectral and textural features to map forest extent and disturbances like deforestation or regrowth.[19] Time-series analysis of these images enables annual monitoring of net changes, with methods like Landsat-based change detection algorithms quantifying gross gains and losses by comparing pixel trajectories against baseline forest masks.[20] Validation techniques emphasize cross-verification and error quantification to mitigate biases from self-reported national data, which can vary in methodological rigor and political incentives for over- or under-reporting. FAO applies quality assurance protocols, including plausibility checks against historical trends, peer consultations with experts, and reconciliation of discrepancies via remote sensing benchmarks, while statistical confidence intervals from NFI designs provide uncertainty estimates derived from design-based or model-assisted inference.[21] Independent ground truthing—via field validation plots or high-resolution drone surveys—calibrates remote sensing products, with accuracy assessments reporting producer's and user's accuracies often exceeding 85% for forest/non-forest classification when fused with ancillary data like topography or soil maps.[22] Discrepancies between sources, such as higher resolution satellite estimates versus coarser NFI extrapolations, are resolved through hybrid approaches like area-based LiDAR modeling validated against plot networks, ensuring robustness against spatial autocorrelation and overfitting in predictive models.[23]Data Sources and Reliability
FAO Global Forest Resources Assessment
The Global Forest Resources Assessment (FRA) is the Food and Agriculture Organization of the United Nations' (FAO) periodic evaluation of global forest resources, encompassing data on extent, condition, management, and trends across 236 countries and territories.[5] First conducted in 1948, the FRA has evolved into a quinquennial report since the 1990s, with the most recent edition, FRA 2025, released on October 21, 2025, providing updated estimates for reference years including 1990, 2000, 2010, 2015, and 2020.[5] [24] It serves as the primary source for country-level forest area statistics, supporting indicators like Sustainable Development Goal 15.2.1 on progress toward sustainable forest management.[5] Data collection relies on two main pillars: official country reports prepared by nationally nominated correspondents using standardized FAO questionnaires, and FAO-conducted remote sensing surveys for validation and gap-filling.[1] [18] Countries report on over 60 variables, drawing from national inventories, government statistics, and sometimes their own remote sensing, while FAO's Remote Sensing Survey (RSS)—introduced in FRA 2010 and expanded thereafter—employs photointerpretation of high-resolution satellite imagery from a global sample to independently estimate forest extent and annual changes.[25] [26] This hybrid approach harmonizes disparate national methods into comparable global aggregates, with forest defined as land spanning more than 0.5 hectares with trees higher than 5 meters and canopy cover of at least 10 percent, naturally regenerated or planted.[1] For country-specific forest area rankings, the FRA compiles self-reported extents adjusted for consistency via FAO's imputation models where data gaps exist, incorporating RSS results to reconcile discrepancies between reported and observed changes.[9] FRA 2025, for instance, reports a global forest area of approximately 4.05 billion hectares in 2020, with Russia, Brazil, and Canada leading in total extent based on these harmonized figures.[24] Trends are calculated as net changes, accounting for gains from afforestation and losses from deforestation or natural causes. The FRA's reliability stems from its transparent, participatory process involving over 700 contributors and tiered data quality classifications, where 89 percent of global forest area in prior assessments fell into the two highest tiers based on methodological rigor. However, limitations persist due to heavy dependence on self-reported national data, which in developing countries often lacks recent inventories or full remote sensing integration, leading to potential underestimation of degradation and overestimation of intact forests.[27] [28] Critics note that without universal ground-truthing, political incentives may inflate reported areas, as evidenced by discrepancies between FRA figures and independent satellite analyses in regions like the tropics.[29] Despite these issues, the FRA remains the most comprehensive official dataset, with ongoing enhancements like expanded RSS coverage improving accuracy over time.[5]Satellite-Based Monitoring Systems
Satellite-based monitoring systems employ remote sensing technologies, including optical and synthetic aperture radar (SAR) imagery, to derive global forest cover estimates and detect changes such as deforestation and regrowth, providing data that can be aggregated to national levels with reduced reliance on potentially biased ground inventories. These approaches leverage satellites like Landsat, MODIS, Sentinel, and ALOS for wall-to-wall coverage, enabling consistent, repeatable assessments over time.[30] Unlike FAO's country-submitted data, satellite methods prioritize empirical pixel-based classification, often validated against field samples, though they vary in resolution, forest thresholds (e.g., minimum canopy cover of 10-30%), and sensitivity to disturbances like selective logging.[31] The Hansen Global Forest Change dataset, produced by the University of Maryland using time-series analysis of over 654,000 Landsat images, quantifies tree canopy cover in 2000, subsequent loss (any stand-replacement event or canopy removal), and gain up to 2024 at 30-meter resolution worldwide. Forest loss is detected via spectral changes indicating disturbances exceeding 50% canopy reduction in a pixel, allowing country-level aggregation; for instance, it documented 425 million hectares of gross tree cover loss globally from 2001-2023, with Brazil and Indonesia accounting for over 25% of humid tropical losses. This dataset underpins platforms like Global Forest Watch, which disaggregates changes by administrative boundaries and reveals discrepancies with FAO reports, such as 2-3 times higher annual deforestation in the Amazon during 2000-2010.[32][31][33] The European Space Agency's CCI Land Cover initiative generates annual discrete classification maps from 1992 to 2022 at 300-meter resolution using primarily MERIS and PROBA-V optical data, categorizing pixels into 22 classes including "tree cover" (woody vegetation >15% cover and >2 meters height). Aggregated to countries, these maps estimate forest extents aligning closely with FAO for boreal regions but diverging in tropics due to finer detection of fragmentation; validation against ground data yields 70-80% accuracy for forest classes.[34][35] NASA's MODIS Vegetation Continuous Fields (VCF) product delivers sub-pixel fractional estimates of tree cover percentage annually at 250-meter resolution since 2000, derived from training high-resolution imagery on MODIS reflectance data, suitable for broad national trends but limited by coarser scale for precise boundaries or small forests. It reports global tree cover at approximately 30-40% of land area in baseline years, with updates tracking decadal declines of 1-2% in woody cover.[36][37] Japan Aerospace Exploration Agency (JAXA) systems, utilizing L-band SAR from ALOS-2, produce global forest/non-forest maps at 25-meter resolution for periods like 2007-2015 and support the JJ-FAST early warning tool, which monitors deforestation alerts in 78 tropical countries every 1.5 months regardless of cloud cover. SAR's penetration of canopy enables biomass estimation and detection of subtle changes missed by optical sensors, with applications showing annual tropical losses of 5-7 million hectares in recent years.[38][39] Collectively, these systems offer higher temporal granularity and objectivity than traditional surveys, facilitating cross-validation; however, aggregation to country totals requires harmonizing definitions, as satellite-derived losses often exceed FAO figures by 20-50% in developing nations due to inclusion of degradation versus strict crown cover criteria.[30][40]Discrepancies Between Sources
Discrepancies in estimates of countries' forest areas stem from divergent definitions of forest, methodologies for data collection, and the quality of underlying inputs. The FAO's Global Forest Resources Assessment (FRA) defines forest as land spanning more than 0.5 hectares with trees higher than 5 meters and at least 10% canopy cover, but relies on self-reported data from countries, which vary in accuracy, timeliness, and adherence to the definition.[41] In contrast, satellite-based datasets like those from the University of Maryland (UMD) integrated into Global Forest Watch (GFW) emphasize tree canopy cover exceeding 30% at a 5-meter height threshold, capturing broader tree extent including plantations but excluding temporarily unstocked areas classified as forest under FRA criteria.[42] These differences result in varying totals and rankings, with FRA often reporting higher areas in regions dependent on national inventories and UMD/GFW showing expansions where commercial tree plantations are prevalent.[42] Globally, FRA 2020 estimated 4,059 million hectares of forest, while UMD/GFW reported 4,018 million hectares for the same year, a 1% divergence reflecting definitional and methodological variances.[42] Regionally, discrepancies widen: UMD estimates exceed FRA by 24.8% in Oceania due to inclusion of non-forest tree covers, but fall 11.5% short in North and Central America, where FRA incorporates country-reported gains from afforestation not aligned with satellite-detected canopy.[42] Country-level examples highlight these issues; Malaysia's FRA figure stands at 19.1 million hectares, versus UMD's 28.6 million, primarily because UMD counts oil palm estates as tree cover, whereas FRA excludes them absent explicit forest designation.[42] In African nations, FAO data inconsistencies with remote sensing arise from inconsistent classification of wooded savannas as closed or open forest; for Gabon and Cameroon, FRA estimates deviate from map- and satellite-derived figures, such as those from Mayaux et al. (1998), due to poor primary data and limited ground validation in tropical zones.[29] FRA's focus on permanent land-use change for deforestation—yielding a global average of 10 million hectares lost annually from 2010–2020—contrasts with GFW's tracking of all tree cover loss, including temporary events like wildfires or logging, which reached 24 million hectares in 2019 and alters perceived rates in fire-prone countries like Australia or Indonesia.[41] Reliability challenges compound these gaps: country reports to FRA, as in Nigeria's revisions from outdated 2000 baselines in FRA 2020, introduce potential political or capacity-based biases, while satellite data faces limitations from cloud obstruction, algorithm thresholds, and exclusion of sub-canopy changes.[42][29] Such variances affect rankings, with UMD/GFW elevating countries with dense plantations (e.g., potentially boosting Southeast Asian totals) relative to FRA's stricter land-use lens, underscoring the need for hybrid approaches combining remote sensing with validated ground data for cross-source reconciliation.[41]Global and Continental Overview
Worldwide Forest Cover Totals and Trends
As of the Food and Agriculture Organization's (FAO) Global Forest Resources Assessment 2025, the world's total forest area stands at 4.14 billion hectares, encompassing approximately 32 percent of the Earth's total land area.[24] This figure reflects a slight increase from the 4.06 billion hectares reported in the 2020 assessment, attributed to ongoing afforestation and natural expansion efforts offsetting some losses. Of this area, more than 90 percent consists of naturally regenerated forests, with the remainder from planted forests.[43] Global forest trends indicate a persistent net loss, though at a decelerating rate. The annual net forest loss decreased from 10.7 million hectares in 1990 to 4.7 million hectares per year during the 2020-2025 period, representing a more than halving of the deforestation rate since the early 1990s.[44] This net change accounts for deforestation (gross loss) minus forest expansion and afforestation (gains), with tropical regions experiencing the highest losses while gains occur primarily in temperate and boreal zones.[45] Satellite-based systems like Global Forest Watch report higher gross tree cover losses—26.8 million hectares in 2024 alone—but these metrics differ from FAO's forest definition, which requires canopy cover of at least 10 percent over 0.5 hectares, potentially leading to discrepancies in trend assessments.[46] Despite the slowdown, primary forests—those with native species and high biodiversity—continue to decline, comprising about 37 percent of total forest area in 2025, down from previous decades due to conversion for agriculture and infrastructure.[47] The FAO's reliance on country-reported data, harmonized through standardized methodologies, provides the most comprehensive global estimate, though underreporting in some developing nations may underestimate losses, as cross-verified by remote sensing where available.[5] Overall, while policy interventions have curbed rates, sustained net losses underscore the need for enhanced protection to stabilize cover above current levels.[45]Continental Forest Area Distributions
The distribution of global forest area varies significantly across continents, reflecting diverse ecological zones and historical land use patterns. According to the Food and Agriculture Organization's (FAO) Global Forest Resources Assessment (FRA) 2020, Europe accounts for the largest continental share at approximately 1.01 billion hectares, or 25% of the world's total forest area of 4.06 billion hectares, primarily due to vast boreal forests spanning Russia and Scandinavia. South America holds the second-largest portion with around 888 million hectares (22%), dominated by tropical rainforests in the Amazon Basin across Brazil, Peru, and other nations. North America follows with 721 million hectares (18%), encompassing temperate and boreal forests in Canada and the United States. Africa's forest area totals 624 million hectares (15%), concentrated in tropical regions such as the Congo Basin, though it experiences high rates of net loss due to agricultural expansion and logging. Asia contributes 570 million hectares (14%), with significant coverage in Southeast Asian rainforests and East Asian temperate forests, excluding Russia's Asian territories classified under Europe in FAO regional groupings. Oceania, including Australia and Pacific islands, has the smallest share at 186 million hectares (5%), featuring eucalypt-dominated woodlands and rainforests in Papua New Guinea. Antarctica has negligible forest cover, estimated at zero hectares. The FAO's FRA 2025 updates the global total to 4.14 billion hectares, indicating a slight net increase from 2020 amid slowing deforestation rates, but regional distributions remain broadly consistent with prior assessments, as gains in Asia and Europe offset losses elsewhere.[24] Boreal forests, prevalent in Europe and North America, comprise about 27% of global forests and exhibit relative stability, while tropical forests in South America, Africa, and Asia (45% of total) face ongoing pressures from conversion to agriculture. These patterns underscore the concentration of forest resources in fewer continents, with Europe and the Americas together holding over 60% of the world's forests.[48]| Continent | Forest Area (million ha, 2020) | Share of Global (%) |
|---|---|---|
| Europe | 1,010 | 25 |
| South America | 888 | 22 |
| North America | 721 | 18 |
| Africa | 624 | 15 |
| Asia | 570 | 14 |
| Oceania | 186 | 5 |
| Antarctica | 0 | 0 |
Net Versus Gross Forest Changes
Net forest area change measures the algebraic difference between forest gains and losses over a specified period, resulting in a single figure that can be positive, negative, or zero.[3] This metric, as reported in the FAO's Global Forest Resources Assessment (FRA), aggregates deforestation (conversion of forest to other land uses) against gains from natural expansion, afforestation, and other increases in forest cover.[49] For the period 2015–2025, the FRA 2025 estimates an annual net global forest loss of 4.12 million hectares, a decline from 10.7 million hectares per year in the 1990s.[24] Gross forest changes, by contrast, quantify total deforestation and total gains independently, without offsetting one against the other, providing a fuller picture of turnover in forest cover. The FAO defines deforestation as the gross annual loss to non-forest uses, independent of subsequent regrowth or replanting, which for 2015–2025 averaged 10.9 million hectares per year—more than double the net loss rate.[24][50] This implies annual gross gains of approximately 6.78 million hectares, primarily from planted forests in temperate and boreal regions offsetting tropical losses. Satellite monitoring by Global Forest Watch (GFW), using Landsat data, reports even higher gross tree cover losses—around 15 million hectares annually in recent years—due to its broader inclusion of degradation and lower crown cover thresholds not captured in FAO definitions.[9] The distinction matters for assessing ecological impacts, as net figures can mask significant gross losses, particularly where natural forests in high-biodiversity tropics are cleared for agriculture while gains occur as lower-diversity plantations elsewhere.[51] FAO's broad forest definition, encompassing areas with as little as 10% tree cover and including commercial plantations, contributes to this offset, potentially understating biodiversity decline and carbon storage disruptions from gross turnover.[52] For instance, between 1990 and 2015, global net forest area declined by 129 million hectares, but gross losses exceeded 200 million hectares when excluding plantation gains.[53] Policy targets like zero net deforestation allow continued gross loss if matched by gains, whereas zero gross deforestation—aimed by initiatives like the New York Declaration on Forests—seeks to halt losses outright to preserve intact ecosystems.[54][55] Discrepancies between FAO net metrics and GFW gross data highlight validation challenges, with satellites revealing higher losses in regions like the Amazon where ground reporting lags.[9]Country Rankings
By Total Forest Area
The ranking of countries by total forest area relies primarily on the Food and Agriculture Organization's (FAO) Global Forest Resources Assessment (GFRA) 2025, which aggregates data from national forest inventories, remote sensing, and other verified sources to estimate forest extent as of 2025. Forest is defined as land spanning a minimum of 0.5 hectares with trees reaching at least 5 meters in height and a canopy cover of more than 10 percent, excluding land primarily used for agriculture or urban purposes.[5] This assessment reports a global total of 4.14 billion hectares, with rankings reflecting absolute area rather than density or proportion of land cover.[24] Russia holds the largest forest area at 832.6 million hectares, dominated by vast boreal taiga forests across Siberia, accounting for roughly 20 percent of worldwide forests.[56][57] Brazil ranks second with 486 million hectares, largely comprising the Amazon basin's tropical rainforests.[58][59] Canada follows in third place with 368.8 million hectares, primarily boreal forests in its northern territories.[58][60] The United States occupies fourth position at approximately 308.9 million hectares, encompassing diverse ecosystems from temperate to subtropical forests.[61] China rounds out the top five with substantial forest cover bolstered by extensive reforestation programs since the 1990s.[61] These leading nations collectively hold over half of the planet's forests, highlighting the concentration of global woodland in a few large territories.[5]| Rank | Country | Forest Area (million hectares) |
|---|---|---|
| 1 | Russia | 832.6 |
| 2 | Brazil | 486.0 |
| 3 | Canada | 368.8 |
| 4 | United States | 308.9 |
| 5 | China | ~220 (estimated from trends) |
By Percentage of Land Area
Forest cover as a percentage of total land area indicates the relative extent of forested terrain within a country's borders, defined by the FAO as land spanning more than 0.5 hectares with trees taller than 5 meters and canopy cover exceeding 10 percent, including both natural and planted forests. This metric highlights countries where forests dominate the landscape, often in tropical regions with dense, undisturbed rainforests, contrasting with arid or heavily agricultural nations. Data from the FAO Global Forest Resources Assessment 2020 reveal that small-to-medium-sized equatorial countries in South America, Africa, and Oceania top the rankings, as their geography favors extensive woodland preservation with limited competing land uses. The following table lists the top 10 sovereign countries by forest area percentage based on FAO 2020 estimates, excluding overseas territories like French Guiana which report even higher figures (e.g., 96.6 percent). These proportions reflect baseline conditions prior to recent minor fluctuations, with tropical moist forests comprising the bulk in leaders like Suriname and Guyana, where logging and mining pose ongoing risks despite protective policies.[63]| Rank | Country | Forest Area (% of Land Area) |
|---|---|---|
| 1 | Suriname | 94.6 |
| 2 | Guyana | 93.5 |
| 3 | Micronesia (Federated States of) | 92.1 |
| 4 | Gabon | 91.3 |

By Annual Change Rates
According to the Food and Agriculture Organization's (FAO) Global Forest Resources Assessment 2025 (FRA 2025), net annual change in forest area is calculated as the difference between gains from natural expansion, afforestation, and natural regeneration and losses from deforestation, harvesting, and other conversions, averaged over the 2015–2025 period using country-reported data harmonized by FAO.[64] Globally, this resulted in a net loss of 4.12 million hectares per year, a decline from higher rates in previous decades, driven by reduced deforestation in some tropical regions offset by continued losses elsewhere.[24] The countries experiencing the largest absolute net annual losses are predominantly in South America and Africa, where agricultural expansion and logging contribute significantly. Brazil recorded the highest net loss at 2.94 million hectares per year, followed by Indonesia at 1.23 million hectares.[65]| Rank | Country | Annual Net Change (1000 ha/year) |
