Study Finds Only 17 Percent of World Peatlands Are Formally Protected Despite Crucial Climate Role

A comprehensive global assessment led by international environmental researchers has revealed that only 17 percent of Earth's peatland ecosystems currently enjoy formal protection within designated conservation areas. The findings underscore a major gap in worldwide conservation efforts, leaving more than four-fifths of these delicate wetlands exposed to human disturbance, drainage, and development. Peatlands, which include bogs, fens, mires, and swamp forests, cover roughly three percent of the global land surface yet store an estimated one-third of all soil carbon. When intact, waterlogged conditions prevent organic plant matter from decomposing, locking carbon away safely for thousands of years. However, when these wetlands are dried out for agriculture, logging, or infrastructure, they shift from powerful carbon sinks into substantial sources of greenhouse gas emissions. The international research initiative evaluated high-resolution spatial datasets spanning tropical peatlands in the Congo Basin and Southeast Asia as well as vast northern peat belts in Canada and Russia. The investigators determined that while global biodiversity treaties target the formal protection of 30 percent of the planet's lands and waters, peatlands significantly trail other ecosystems in legal preservation. In the Democratic Republic of the Congo, field teams from European and African research institutions conducted extensive surveys across the Cuvette Centrale peatlands. The Cuvette Centrale complex covers approximately 145,000 square kilometers and holds roughly 30 billion metric tons of carbon, an amount equivalent to several years of global fossil fuel emissions. The researchers documented that vast portions of this immense basin currently lack formal conservation buffer zones against commercial logging and agricultural concessions. Southeast Asian peat swamp forests, particularly across Indonesia and Malaysia, have faced heavy pressures over recent decades from drainage linked to oil palm and pulpwood plantations. Environmental policy analysts pointed out that drained peat becomes highly combustible, triggering recurring subterranean fires that blanket entire regions in toxic haze and release millions of tons of carbon dioxide into the atmosphere. Northern peatlands across Canada, Scandinavia, and the Russian federation face distinct but equally serious challenges driven by warming temperatures and thawing permafrost. As sub-Arctic soils warm, microbial activity accelerates, speeding up the decomposition of previously frozen organic material. Resource extraction projects and infrastructure corridors also risk altering delicate hydrological networks that keep peat bogs saturated. Ecologists noted that protecting peatland systems delivers benefits far beyond climate regulation. Undisturbed peatlands serve as natural filters that purify regional freshwater supplies and act as giant sponges that absorb floodwaters during severe weather events. They also provide critical habitats for endangered species, including the eastern chimpanzee in Central Africa and the Bornean orangutan in Southeast Asia. The study's authors emphasized that restoring degraded peatlands is substantially more costly and difficult than conserving existing healthy bogs. Rewetting drained peat through canal blocking and ditch filling has shown promise in pilot projects across Europe and North America, but restoring full carbon storage capacity can take decades. Consequently, environmental economists argue that preventative legal protections represent the most cost-effective approach for national governments. International conservation organizations are urging delegates preparing for upcoming multilateral biodiversity summits to establish dedicated peatland targets within national climate action plans. Under the Paris Agreement framework, countries are updating their nationally determined contributions, providing an opportunity to formally include wetland and peatland restoration in statutory emissions targets. Civil society groups and Indigenous community leaders in tropical peat zones have called for greater recognition of traditional land tenure rights as part of protection frameworks. Field data shows that peatlands managed by local communities consistently experience lower rates of deforestation and drainage than unallocated state lands. Integrating local stewardship with transparent legal safeguards is increasingly seen as essential to securing these vital carbon reservoirs.
