Peat lands, critical ecosystems that regulate the climate, are rapidly degrading across 177 countries, jeopardizing global climate goals and biodiversity. The newly released Global Peat land Hotspot Atlas, published by the United Nations Environment Programme (UNEP), emphasizes the urgent need for enhanced protection and restoration efforts. The atlas, which maps peat land distribution and the threats they face. It the importance of safeguarding these ecosystems to secure essential services and mitigate climate change.
THE CRITICAL ROLE OF PEATLANDS IN THE GLOBAL ECOSYSTEM
Peat lands are often referred to as nature’s carbon vaults. They cover only 3-4% of the Earth’s land surface. Yet, they store up to one-third of the world’s soil carbon. This is more than double the carbon found in global forests. These unique ecosystems offer much more than carbon sequestration. Locally, peatlands regulate and purify water, support livelihoods, and help mitigate natural disasters like floods, fires, and droughts. Furthermore, they offer habitats for over 1,000 vulnerable, endangered, and critically endangered species.
Despite their significance, peatlands face many threats, particularly from human activities like agriculture, urbanization, deforestation, and industrial development. These pressures not only contribute to peat land degradation but also release vast amounts of greenhouse gases into the atmosphere.
GLOBAL PEATLAND DEGRADATION: THE SCALE OF THE CRISIS
The Global Peatland Hotspot Atlas reveals alarming trends in peatland degradation, particularly in tropical regions. Every year, approximately 500,000 hectares of intact peatlands—about 0.1% of global peat land area—are destroyed due to human activities, including agriculture, livestock farming, and oil palm plantations. The drainage of peat lands for these purposes leads to subsidence, which exacerbates carbon emissions.
One of the most concerning threats comes from thawing permafrost. It causes peatlands in the Arctic and sub-Arctic regions to rapidly degrade. As temperatures rise due to climate change, the thawing of permafrost releases stored carbon, contributing to further global warming.
Peatlands in more remote areas, such as parts of the sub-Arctic and boreal regions, remain relatively intact. However, the ongoing degradation in other areas is undermining global climate and biodiversity goals.
THE COST OF INACTION: IMPACT ON CLIMATE AND BIODIVERSITY
Degraded peat lands are responsible for 4% of global greenhouse gas emissions originating from human activities. This alarming figure highlights the critical need for peat land restoration as a climate solution. By protecting and rehabilitating peat lands, countries can significantly reduce their carbon footprint. These actions also safeguard biodiversity and enhance local resilience to climate change.
The report urges governments and decision-makers to recognize the value of peat lands. These lands offer a cost-effective strategy for climate mitigation and adaptation. Peat lands help regulate the global climate, providing a host of benefits for local communities. These benefits include cleaner water, reduced risk of natural disasters, and support for endangered species.
UNEP’S GLOBAL PEATLANDS INITIATIVE: A PATH FORWARD
The Global Peat lands Initiative (GPI), led by UNEP, is spearheading efforts to conserve, restore, and sustainably manage peat lands worldwide. GPI uses the Global Peat land Hotspot Atlas. It promotes holistic water management. GPI also encourages a landscape approach to peat land conservation. The initiative focuses on priority areas where peat land protection can have the greatest impact on climate and biodiversity.
UNEP aims to support the restoration of peatlands by enhancing investment in research, monitoring, and protection efforts. It seeks to drive global climate action. The focus on priority regions is crucial. Southeast Asia is one such region where peatland degradation is most severe. Focusing here will be essential to meeting global climate goals.
THE URGENT NEED FOR ACTION
The Global Peatland Hotspot Atlas is a stark reminder of the need for immediate action. We need protection and restoration; otherwise, peatlands will degrade. This degradation will continue to undermine global efforts to combat climate change and preserve biodiversity. Governments, businesses, and local communities must collaborate. They need to protect these invaluable ecosystems. This collaboration will secure a sustainable future for both people and the planet.
As Susan Gardner, Director of the UNEP Ecosystems Division, states, “Peatlands do not just store vast amounts of carbon. They provide essential services that millions of people rely on daily.” Their protection is a fundamental investment in human wellbeing. It is time to act before it is too late.
