An international coalition of scientists, including Dr. Ritesh Kumar, Director of Wetlands International South Asia, has collaboratively defined the most critical and pressing research questions surrounding peatland ecosystems. This comprehensive global roadmap, published in Communications Earth & Environment, is poised to steer future scientific endeavors and policy formulations aimed at preserving these indispensable yet vulnerable natural resources. The study, a monumental undertaking, garnered input from 467 participants spanning 54 nations, meticulously identifying research priorities essential for understanding and protecting peatlands. By synthesizing the collective expertise of global peatland specialists, the research illuminates critical knowledge gaps and pinpoints areas where new insights can yield the most significant impact on climate mitigation, biodiversity conservation, and sustainable land management.
Peatlands: A Critical Climate Ally Under Threat
Peatlands, though occupying a mere three percent of the Earth’s terrestrial surface, hold a remarkable secret: they store more carbon than all the world’s forests combined. When functioning optimally, these waterlogged environments act as enduring carbon sinks, sequestering carbon for millennia. However, their ecological integrity is increasingly imperiled by drainage, wildfires, extraction activities, and land-use transformations. These pressures can rapidly convert peatlands from carbon reservoirs into significant emitters of greenhouse gases. Despite their profound importance for global climate regulation, substantial knowledge deficits persist regarding peatland resilience to climate change, effective restoration techniques, and strategies for their protection that simultaneously support the livelihoods of local and Indigenous communities.
"An effective science-management interface is crucial for nurturing evidence-based policy and programming for nature conservation. These 50 research questions are a guide to the science needed to conserve peatlands of the world and mobilise action," stated Dr. Ritesh Kumar, Director of Wetlands International South Asia, underscoring the critical link between scientific inquiry and practical conservation outcomes.
Eva Hernandez, Global Peatlands Lead at Wetlands International, further emphasized the collaborative spirit and forward-looking nature of this initiative. "While there is plenty of knowledge to act in favour of peatlands, these 50 questions can help do more, better and quicker, and respond to the new questions that come up in a fast evolving world," she remarked. Hernandez added that this exercise exemplifies the power of collective intelligence and will serve as a vital compass for the Peatland Breakthrough initiative, an ambitious global effort dedicated to galvanizing political will, accelerating action, and mobilizing financial resources for the conservation of healthy peatlands.
A Global Consensus on Research Priorities
The impetus for this global research agenda stems from the growing recognition of peatlands’ pivotal role in addressing the climate crisis. As nations increasingly turn to nature-based solutions to meet their climate targets, the need for robust scientific understanding of these ecosystems becomes paramount. Peatland protection and restoration are now integral components of national climate strategies in countries such as the United Kingdom, Ireland, Indonesia, Canada, and Finland, and have secured a place on the international climate and biodiversity agenda.
To establish these research priorities, scientists, practitioners, and policy experts from around the world were engaged in a comprehensive survey. Participants were tasked with identifying the most urgent and unresolved questions across the spectrum of peatland research, encompassing ecology, hydrology, biogeochemistry, climate science, and social sciences. The resulting list of 50 priority questions reflects a global consensus on the most critical areas requiring further investigation, covering a diverse range of peatland types from boreal and temperate to tropical regions. These priorities aim to inform targeted research that can underpin effective conservation and restoration efforts.
Dr. Alice Milner, Associate Professor at Royal Holloway University of London, UK, and lead author of the study, highlighted the significance of this focused approach. "Peatlands are increasingly recognised as critical ecosystems for climate action, but we still don’t have all the answers we need to manage them effectively. By identifying the most urgent research questions, this work helps focus global effort," she explained.
Echoing this sentiment, Dr. Julie Loisel, Associate Professor at the University of Nevada, Reno, USA, and a co-author, noted the broad agreement among peatland stakeholders. "This global survey revealed how much common ground exists among people working with peatlands around the world. Bringing these voices together has allowed us to focus our collective effort on the questions that matter most, and to begin tackling them together," she stated.
Beyond Biophysics: Integrating Social and Governance Dimensions
A crucial aspect of this research agenda is its expansion beyond purely biophysical sciences. A significant number of priority questions delve into governance structures, land-use decision-making processes, and the indispensable role of Indigenous and local knowledge in peatland management. Historically, these socio-economic and cultural dimensions have received less emphasis in global research frameworks, despite their critical influence on the success of conservation initiatives.
Dr. Michelle McKeown, Lecturer in Environmental Geography at University College Cork, Ireland, and a co-author, cautioned against simplistic restoration approaches. "Restoring peatlands is not as simple as just ‘rewetting’," she remarked. "There are important trade-offs, uncertainties, and regional differences that we still don’t fully understand. These priority questions help ensure that peatland management is helping, not harming, climate and biodiversity goals."
Professor Angela Gallego-Sala from the University of Exeter, UK, a co-author, underscored the human dimension of peatlands. "Peatlands are not empty landscapes. They are lived-in, worked landscapes with deep cultural significance. This is particularly true in the tropics, where peatlands can be a resource – sometimes the only one – that provides livelihoods, so it is important that as researchers we acknowledge this and provide answers that are useful to these communities too," she emphasized.
Dr. Monika Ruwaimana, a co-author and Lecturer at Universitas Atma Jaya Yogyakarta, Indonesia, shared her perspective from a tropical peatland landscape. "As someone who grew up in tropical peatland landscapes, it is encouraging to see the global research community paying attention to these ecosystems. This progress reflects a collective effort that has developed over decades, gradually shifting perspectives on the importance of peatlands in the global carbon cycle, from local communities working in the field to international researchers and policymakers," she observed.
Implications for Policy and Future Investment
The growing international interest in peatlands, driven by their potential to contribute to climate targets, necessitates a clear strategic direction for research funding and policy development. Without well-defined research priorities, investments risk being fragmented and short-sighted, potentially hindering long-term conservation success. The identified research questions offer a framework for directing financial resources towards the most impactful areas of inquiry, ensuring that efforts are coordinated and efficient.
The implications of this research are far-reaching. By clarifying what we need to know, it empowers policymakers to make more informed decisions regarding land use, conservation policies, and international climate agreements. It also provides a roadmap for research institutions and funding agencies to allocate resources effectively, fostering a more cohesive and impactful global peatland research community.
The urgency of this agenda is underscored by the inherent duality of peatlands: they can either be a stabilizing force for the climate or, if degraded, a significant accelerant of climate change. "Peatlands can either help stabilise the climate or accelerate its change," stated Dr. McKeown. "Which path we take depends on the knowledge we build, and how quickly we act on it."
This initiative represents a significant step forward in translating scientific understanding into actionable conservation strategies. The collaborative development of this research agenda signifies a global commitment to unlocking the full potential of peatlands as natural allies in the fight against climate change and biodiversity loss, ensuring a more sustainable future for these vital ecosystems and the communities that depend on them.
