UN audit finds 252 million hectares under restoration but says pace must roughly triple by 2030

Ecosystem restoration has moved from the margins of environmental policy to the centre of it over the past five years. The United Nations General Assembly declared 2021 to 2030 the UN Decade on Ecosystem Restoration, a push to prevent, halt and reverse the degradation of landscapes, fresh water and oceans. In 2022, governments adopted the Kunming-Montreal Global Biodiversity Framework, whose second target commits them to placing at least 30 percent of degraded terrestrial, freshwater, marine and coastal ecosystems under effective restoration by 2030. Those promises were made without any reliable way of measuring whether they were being kept.

That measurement gap has now been partly closed. On 29 October 2026, at a high-level event during the UN Biodiversity Conference, known as COP17, in Yerevan, Armenia, three UN bodies published the first comprehensive global stocktake of restoration commitments and delivery. The report, titled "Nature's comeback: scaling ecosystem restoration for people and planet", was co-published by the UN Environment Programme, the Food and Agriculture Organization and the Secretariat of the Convention on Biological Diversity.

Its headline finding is double-edged. The world has documented more restoration than ever before, and the area involved is vast, roughly the size of Kazakhstan, the world's ninth largest country. But the same data show that the effort sits far below what governments themselves promised, and that the shortfall is concentrated in the ecosystems deteriorating fastest.

The report draws on official country data and initiatives submitted to FAO's Framework for Ecosystem Restoration Monitoring. It is the first assessment to cover all ecosystem types at once, and the most complete accounting to date of progress against a separate, older pledge to restore around one billion hectares.

Key Facts

UNEP reported on October 29 that 252 million hectares of degraded ecosystems across 149 countries are documented as under restoration, the largest recorded area to date, and that the work has created more than one million green jobs. The figure breaks down as roughly 232 million hectares of terrestrial ecosystems, 11 million hectares of freshwater, 5.7 million hectares of marine and coastal systems, and 3.2 million hectares that could not be assigned to a category.

FAO reported on October 28 that countries have committed to restoring approximately 738 million hectares, the area implied by the 30 percent goal. Documented implementation would therefore need to roughly triple to meet the 2030 deadline. The agency also cautioned that an area under restoration is not an area that has recovered, since rebuilding biodiversity and ecosystem function can take decades.

The regional spread is lopsided. Asia accounts for 192.2 million hectares, Africa 36.3 million, Europe 9.1 million, North and Central America 5.8 million, South America 5.4 million and Oceania 3.2 million. China reports the largest terrestrial restoration area at 127.4 million hectares, with substantial areas also recorded in Mongolia and Kazakhstan. UNEP notes that these figures reflect land area and monitoring capacity rather than the quality of performance.

Progress is most advanced on land, where 49 percent of the estimated terrestrial target is under restoration. Marine and coastal systems have reached 23 percent, and freshwater only 4.5 percent. Just 62 countries documented freshwater restoration and 46 documented marine and coastal work. Even so, the share of countries reporting wetland restoration programmes rose from 8 percent in 2022 to 54 percent.

Money is the other gap. The report puts traceable global restoration finance at about US$64 billion in 2022 and says annual investment must reach US$296 billion by 2030, more than four times the current level. Public funding dominates and private investment remains limited. The 35 UN World Restoration Flagships report 18 million hectares under restoration, more than 1.1 million jobs created and over 1.2 million people trained.

Analysis

The numbers invite two readings, and the report supports both. A record 252 million hectares is a genuine achievement, and the flagships show that restoration can produce measurable returns, from mountain gorillas in East Africa to Ganges river dolphins in India. The Straits Times reported on October 29 that the restored area is equivalent to the size of Argentina or Algeria. AFP reported on October 29 that Doreen Robinson of UNEP called it "the largest documented restoration effort in history".

The second reading is less flattering. The bigger picture here is that restoration is being outpaced by degradation, and that governments are counting hectares they have promised rather than hectares they have repaired. The 252 million figure is 34 percent of the indicative benchmark for the 30 percent goal, and the freshwater number, at 4.5 percent, is close to a rounding error against the scale of the problem. The report itself warns that freshwater, marine and coastal ecosystems are degrading at the highest rates while attracting the least documented work.

There is also a measurement problem that flatters the totals. FAO reported that 46 countries submitted no quantitative restoration progress data under any framework assessed, and that differing definitions and methods make cross-country comparison difficult. A stocktake that cannot see 46 of its members is not a full picture, and the concentration of reported area in a handful of large countries suggests that administrative capacity, not ecological need, shapes the map. The report acknowledges as much when it says the regional figures reflect land area and monitoring capacity rather than performance.

The financing argument is where the report makes its sharpest judgement. Restoration costs are immediate, while benefits such as flood protection, cleaner water and carbon storage arrive years later, so private capital stays away unless policy changes the arithmetic. UNEP argues for moving from financing isolated projects to building "restoration economies" in which protecting nature is a viable long-term activity. Just Energy News reported on October 29 that Inger Andersen, UNEP's executive director, said the world is "still not restoring nature at the scale or speed required" and called for systemwide action by 2030.

Why It Matters

The stakes are not only ecological. The report estimates that meeting the finance target could generate up to 32 million additional jobs worldwide by 2030, on top of the more than one million already created. It also cites research suggesting that restoring just 15 percent of priority areas worldwide could capture and store carbon equivalent to 30 percent of cumulative CO2 emissions since the Industrial Revolution and help prevent 60 percent of species extinctions.

Those figures explain why restoration has become a climate and development issue as much as a conservation one. Forests, wetlands and coastal systems buffer floods, filter water and support food systems, and their loss is felt first by the communities least able to pay for substitutes. The report's emphasis on freshwater is pointed: rivers and lakes are degrading fastest and receiving the smallest share of documented investment.

For governments, the stocktake also sets a baseline against which national pledges will be judged. Because the data come from countries themselves, through FAO's monitoring framework, the next edition will be hard to dismiss as an external critique. The gap between the 738 million hectares committed and the 252 million documented is now a matter of public record.

Next Up

COP17 continues in Yerevan until the end of the week, where the report is being used to press for stronger finance commitments and better monitoring. The five newly named UN World Restoration Flagships, in China, Colombia, Ethiopia, Italy and the United States, will be expected to demonstrate results that can be replicated elsewhere.

The decisive test comes before 2030. Countries must convert pledges into reported hectares, close the data gaps that leave 46 countries invisible, and shift public and private finance toward the US$296 billion annual figure. On current evidence, the report suggests, the world has built momentum but not yet the scale.
