Kazakhstan reports the third-largest area of land under restoration worldwide and Poland the second-largest freshwater area, a UN report finds, as global restoration reaches 252mn hectares.
The report, "Nature's comeback - scaling ecosystem restoration for people and planet", was published on October 29 by the UN Food and Agriculture Organization (FAO), the UN Environment Programme (UNEP) and the Secretariat of the Convention on Biological Diversity (CBD) at the UN biodiversity conference, COP17, which opened in Yerevan on October 19. It counts restoration under way in 149 countries, linked to more than 1mn green jobs, and calls it the largest documented global restoration effort to date.
For Central Asia, where deserts, steppe and the dried-out Aral Sea bed make land degradation a daily economic problem, the UN's first global stocktake shows a region with some of the world's biggest programmes on paper. Europe looks thinner: it accounts for just 3.6% of the land under restoration worldwide, its pledges cover a smaller share of its territory than in any other region except North and Central America, and the share of its land classed as degraded is rising.
"Five years into the UN Decade, the message is clear: restoration works," said FAO Director-General Qu Dongyu.
"Today, we are witnessing the makings of one of the largest movements for nature in recorded history," said UNEP Executive Director Inger Andersen. "Yet, at the halfway point of the UN Decade on Ecosystem Restoration, we are still not restoring nature at the scale or speed required."
A quarter of the way there
The 252mn hectares under restoration amount to about a quarter of the roughly 1bn hectares that countries have pledged to restore. "Restoration is underway at an unprecedented scale," the report said, but "implementation needs to triple to meet Target 2 of the Kunming-Montreal Global Biodiversity Framework", which calls for 30% of degraded land, freshwater, marine and coastal areas to be under effective restoration by 2030.
Land is closest to the goal, with restoration of terrestrial areas at nearly half the global target. Rivers, lakes, wetlands and seas lag far behind: only 11mn hectares of freshwater habitat in 62 countries and 5.7mn hectares of marine and coastal habitat in 46 countries are documented as under restoration.
"Reported restoration lags far behind ambition in both freshwater (inland water) and marine and coastal ecosystems, yet these ecosystems are degrading at the highest rates," the report said. The share of countries reporting wetland restoration or rehabilitation programmes has risen from 8% to 54% since 2022, and the authors caution that thin reporting on aquatic restoration may understate progress.
Asia accounts for 192.2mn hectares of the global total, followed by Africa with 36.3mn hectares, Europe with 9.1mn hectares, North and Central America with 5.8mn hectares, South America with 5.4mn hectares and Oceania with 3.2mn hectares. China alone reports 127.4mn hectares of land under restoration, about 13.5% of its territory.
Money is the main constraint. Annual restoration finance needs to rise more than fourfold, from $64bn to $296bn by 2030, led by agroforestry ($87bn a year), restorative reforestation ($52bn), peatland restoration ($44bn) and seagrass restoration ($28bn). That investment could create up to 32mn jobs worldwide by 2030, the agencies estimate.
"We cannot expect to fix nature with one hand while we destroy it with the other one," said CBD Executive Secretary Astrid Schomaker. "Governments must address the drivers of ecosystem degradation and invest in monitoring mechanisms to ensure the durability of the restoration movement to date."
Steppe giants
Kazakhstan reports 8.13mn hectares of land under restoration, equivalent to 3% of its territory and the third-largest area after China and Mongolia, which reports 12.18mn hectares, or 7.8% of its land. Kazakhstan also features among the 10 countries with the largest freshwater areas under restoration, at 0.33mn hectares. The report stresses that its country charts "should not be interpreted as a ranking of country restoration performance", since the figures also depend on land area and how well countries monitor and report.
Kazakhstan's Altyn Dala, or Golden Steppe, initiative is one of the UN World Restoration Flagships, and the report lists the return of saiga antelope and wild horses there among the species recoveries the flagships have delivered. The saiga population has grown from 21,000 in 2003 to an estimated 4.7mn this spring, President Kassym-Jomart Tokayev told the COP17 leaders' summit in Yerevan in mid-October.
Conservationists say the herds do more than recover numbers. Bringing back large grazers to the steppe thins out the dry grass that has fed a surge in wildfires across grasslands covering more than 40% of Kazakhstan. Astana has also proposed a regional Green Shield of Central Asia, a network of protective forest belts against desertification and dust storms, building on the forest belt around the capital that has grown to 102,000 hectares since 1997.
Snow leopards and mountains
Snow leopards in Kyrgyzstan appear alongside mountain gorillas in East Africa, jaguars in Brazil and Ganges river dolphins in India on the list of species the flagships have helped. Kyrgyzstan is part of a multi-country mountain flagship with Rwanda, Serbia and Uganda, recognised in 2022, which works to reduce conflict between herders and wildlife through better grazing practices and community wildlife monitoring. Four adult snow leopards were recorded and two cubs born in each of 2020 and 2021 in the Kyrgyz project area, according to the UN Decade on Ecosystem Restoration. In Serbia the same flagship is restoring forest and pasture in the Kucaj-Beljanica and Stara Planina nature parks.
Bishkek has since gone further, creating a 792,000-hectare ecological corridor in Issyk-Kul region in 2025 to link snow leopard habitats, and opening the Ak Ilbirs research and rehabilitation centre on October 23.
Mountains are also the theme Armenia has pushed as COP17 host. On October 28 it launched with UNEP a Yerevan Platform on Mountains and Related Freshwater Ecosystems; mountains supply 55-60% of the world's annual freshwater flows, but only 19% of mountain areas are protected.
"The reality is what happens in mountains does not stay in the mountains," Andersen said at the launch.
The Aral Sea's long shadow
Further south, the report has no country figures for Uzbekistan, Tajikistan or Turkmenistan, but the region's restoration challenge is defined by the Aral Sea, which has lost around 90% of its surface area in 50 years. Uzbekistan says it has established more than 2mn hectares of forest plantations on the former seabed and plans to create or restore forests on 1.27mn hectares in 2026-2030. Kazakhstan has committed to restoring 1.1mn hectares of the seabed on its side, half of which has already been planted.
Dust and salt from the Aralkum desert that formed on the dry bed can reach Tajikistan's glaciers and speed their melting, experts warn. Drought already affects more than 26mn people in Central Asia, where over 80% of territory is desert and steppe, part of a wider global disaster season of heat, fire and water shortage. Uzbekistan has cut its water stress from 169% in 2017 to 122% in 2021, but still withdraws more freshwater than it renews.
Research in Rwanda and the drylands of Central Asia cited in the report found that "pursuing each Convention's goals independently requires far more money than most developing countries have available". The biggest single efficiency gain came from setting up one national monitoring system for restoration.
Data collection is still fragmented in most countries, and "harmonizing these into one national system for restoration is where the biggest gains lie", the report said. The Eastern Europe, Caucasus and Central Asia Forest Landscape Restoration Initiative (ECCA30) is one of the regional programmes it names alongside Africa's Great Green Wall.
Europe's wetlands
Europe's 9.1mn hectares are skewed towards water. About 4.1mn hectares, 72% of all marine and coastal restoration documented worldwide, are in European seas, mostly off Ireland. Another 1.8mn hectares are freshwater sites, against only 3.2mn hectares of land.
Poland reports 0.97mn hectares of freshwater habitat under restoration, equivalent to 3.2% of its land area, second only to Indonesia's 5.99mn hectares of peatland restoration. Poland and Estonia each report 0.03mn hectares of marine and coastal restoration. Warsaw voted against the EU's Nature Restoration Law in 2024 but failed to block it; the regulation requires restoration measures on at least 30% of habitats not in good condition by 2030 and the return of at least 25,000 km of rivers to a free-flowing state.
Ukraine dominates Europe's freshwater pledges. Of 4.1mn hectares of freshwater restoration commitments identified through the Convention on Wetlands, most are in Europe, and "This pattern is strongly influenced by a commitment of approximately 3 Mha reported by Ukraine", the report said. The scale of the task there grew with the war: the destruction of the Kakhovka dam in 2023 flooded 80,000 hectares of protected areas, according to Ukraine's environment ministry at the time.
Hungary is named among countries with wetland and peatland commitments in their national plans. Peatlands cover only 3-4% of the world's land but store up to a third of its soil carbon, and degraded peatlands produce about 4% of global man-made emissions, yet they "remain among the most under-represented ecosystems in national restoration commitments and reports", the report said. Around the Baltic, Estonia and its neighbours have discussed rewetting bogs as a natural barrier against Russian forces.
On land, Europe's pledges total 60.45mn hectares, or 2.7% of its land area, against 11.3% in Africa and 10% in Asia. UN data cited in the report show the degraded share of Europe's land rising from 11.3% in 2015 to 14.7% in 2019, though the authors warn that changes in methodology may account for part of the increase. Of the 63 countries that gave the CBD no restoration figures in their latest national reports, 17 are European.
Who pays
Traceable restoration finance reached $64bn in 2022, but 88% of public money went through domestic spending on agriculture, forestry and fishing, and five countries, China, the US, Canada, Japan and Turkey, accounted for 76% of it. Turkey also reports 3.39mn hectares of land under restoration, the seventh-largest area. Development finance aimed at restoration totalled only $1.2bn.
Asia needs the largest increase, about $102bn a year by 2030, while the Near East and reforming economies, which include the former Soviet states, need $39bn, the report said, citing UNEP estimates.
"Building restoration economies can help shift the balance from an economy that depletes nature to one that values and invests in its recovery," the report said. "Thirty percent by 2030 is a milestone, not the end of the restoration journey."
