Understanding Peatlands: Nature's Critical Carbon Reservoirs
Peatlands are among the most significant natural carbon sinks on Earth, storing vast amounts of carbon and playing a crucial role in mitigating climate change. Research at Queen's University Belfast has focused on understanding the complex dynamics of these ecosystems, their vulnerability to environmental changes, and their potential as nature-based climate solutions. This research is vital in informing global strategies for climate mitigation and sustainable management of peatland resources.
Research Challenge
The Vulnerability of Peatlands: Threats from Climate Change and Human Activity
Peatlands, though critical for carbon storage, are highly sensitive to changes in climate and land use. Human activities such as drainage for agriculture, forestry, and peat extraction have degraded these ecosystems, leading to significant carbon emissions. The challenge lies in understanding how peatlands respond to environmental changes over time and how they can be protected or restored to enhance their role in climate change mitigation.
Our Approach
Investigating Peatland Dynamics: Insights from Groundbreaking Research
The research conducted by Queen’s University Belfast delves into the eco-hydrological dynamics of peatlands, examining their functioning across various climates, from temperate regions to the Arctic and tropics. By using high-resolution dating techniques and ecological indicators like testate amoebae, the research reconstructs past environmental conditions to predict future changes in peatland behavior. Key areas of study include the restoration of degraded peatlands, the role of tropical peatlands in the global carbon cycle, and the impact of human activities on these ecosystems. This research not only advances scientific understanding but also supports the development of strategies for peatland conservation and restoration globally.
Much of the research took place the state of the art 14CHRONO Centre at Queen’s, the only high precision radiocarbon dating and isotope analysis laboratory on the Island of Ireland.
"Peatlands can be considered as natural time capsules, and as the peat is forming, over time they can lock in information about climate change, about ecosystems and also about human impacts on the landscape."

From Research to Policy: The Global Influence of Peatland Conservation
The findings from Queen's research have significant implications for climate policy and conservation efforts. The research highlights the importance of peatlands in global carbon sequestration and supports their inclusion in climate mitigation strategies. It has informed the development of evidence-based policies aimed at protecting and restoring peatlands, contributing to global efforts to limit temperature rise and achieve climate goals such as those outlined in the Paris Agreement. Furthermore, the research has practical applications in guiding sustainable management practices that balance human needs with the conservation of peatland ecosystems.
