Protecting Southeast AsiaS Peatlands and Mangroves: A Climate Change solution
Preserving Southeast Asia’s peatlands and mangroves could significantly mitigate the region’s land-use carbon emissions.Covering just 5% of the region’s terrestrial land, these ecosystems store over 90% of their carbon in the soil, making them among the most efficient natural carbon sinks globally. According to a new international study published in Nature Communications, conserving and restoring these vital ecosystems has the potential to reduce land-use carbon emissions by more than 50%.
The research, conducted by a team of scientists from the National university of singapore, Nanyang Technological University Singapore, and James Cook University Australia, highlights the critical role of peatlands and mangroves in combating climate change. These ecosystems act as natural carbon sinks, absorbing and storing vast amounts of atmospheric carbon dioxide.
However, when disturbed by activities like land-use changes, these ecosystems release meaningful carbon back into the atmosphere, contributing to global warming. Moreover, peatland degradation during dry periods, frequently enough associated with el Niño events, releases massive amounts of carbon and worsens air quality through haze events affecting countries like Singapore.
The climate Benefits: A Powerful Natural Solution
“If we conserved and restored the carbon-dense peatlands and mangroves in Southeast Asia, we could mitigate approximately 770 megatonnes of CO2 equivalent (MtCO2e) annually, or nearly double Malaysia’s national greenhouse gas emissions in 2023,” explained Associate Professor Massimo Lupascu, principal investigator and senior author of the study.
“Our research underscores the immense climate benefits of protecting these ecosystems, making them a pragmatic and effective natural climate solution for ASEAN countries,” added Assoc Prof Lupascu, from the Department of Geography at the NUS Faculty of Arts and Social Sciences.
Integrating Peatlands and Mangroves into Climate Action Plans
Professor David Taylor, co-author and Head of the NUS Department of Geography, emphasizes the importance of incorporating both peatlands and mangroves into countries’ nationally Determined Contributions (NDCs) under the Paris Agreement. “Including both peatlands and mangroves in these updated national climate action plans can certainly contribute to increasing the ambition of countries across the region through the setting of higher emissions reduction targets,” he said. “However, this would involve considerable investment in effective conservation and restoration efforts.”
The Urgent Need for Conservation and Restoration
Southeast Asia is home to some of the world’s largest areas of tropical peatlands and mangroves.These unique ecosystems share water-saturated,oxygen-limited soils that slow down the decomposition of organic matter,allowing them to efficiently store carbon. However, the carbon stored in these soils is “irrecoverable,” meaning it cannot be easily replaced if lost to human activities.
Protecting and restoring these vital ecosystems is crucial for mitigating climate change and preserving biodiversity.By investing in sustainable land-use practices and implementing effective conservation measures, Southeast Asian countries can harness the immense climate benefits of peatlands and mangroves while ensuring a sustainable future for generations to come.
Securing Southeast Asia’s Future: The Power of Peatlands and Mangroves
A groundbreaking study published in Nature Communications reveals the immense potential of peat swamp forest and mangrove conservation in combating climate change across Southeast Asia. The research, led by Dr. Sigit Sasmito of TropWATER,James Cook University,underscores the critical role these ecosystems play in storing carbon and mitigating land-use emissions.
Unveiling the Carbon Powerhouses
While frequently enough overlooked, peatlands and mangroves act as natural carbon sinks, storing vast amounts of carbon within their soils. “Wetland soils may have little agronomic value, as it is indeed generally not well-suited for traditional farming or crop cultivation, but they are unmatched in their ability to store and preserve carbon,”
explained Assistant Professor Alain Taillardat, co-author of the study and principal investigator at the Wetland Carbon Lab at the Asian School of the Environment, NTU Singapore.
Recognizing this immense carbon storage capacity, the researchers propose unlocking the economic potential of these ecosystems through carbon credit schemes. “If carbon were valued like other critical commodities, such as being traded on the carbon credits market, it could unlock vast opportunities for conservation and restoration projects,” suggested Asst Prof Taillardat.
“This will enable local communities to lead carbon management efforts with a win-win scenario where livelihoods and sustainable ecosystems thrive together.”
Towards a Climate-Resilient Future
The study provides crucial facts on emissions from disturbed peatlands and mangroves across Southeast Asia between 2001 and 2022, offering policymakers valuable data to pinpoint critical areas for intervention and prioritize conservation efforts. Dr.Sasmito emphasized, “By investing in the conservation of peatlands and mangroves, Southeast Asia can lead the world in deploying cost-effective, nature-based solutions that deliver enduring climate and biodiversity benefits.”
Integrating peatland and mangrove conservation into national climate strategies is a crucial step, according to the researchers. “These ecosystems pack a climate mitigation punch far beyond their size, offering one of the most scalable and impactful natural solutions to combat the planet’s climate crisis,”
stated Dr. Sasmito.
call to Action
The findings of this study present a clear and compelling case for prioritizing peatland and mangrove conservation in Southeast Asia. By investing in these invaluable ecosystems, governments, organizations, and individuals can contribute to a more sustainable and climate-resilient future for the region and the world.

Protecting Southeast Asia’s Peatlands and Mangroves: An Interview with Dr. Sigit Sasmito
Southeast Asia’s peatlands and mangroves are critical carbon sinks, facing increasing pressure from land-use changes. Dr. Sigit Sasmito, a leading researcher at TropWATER, James Cook University, sheds light on the immense potential of these ecosystems in combating climate change.
Unveiling the Carbon Powerhouses
Dr. Sasmito, your recent research highlights the profound impact of Southeast Asia’s peatlands and mangroves on carbon storage. Can you elaborate on the unique characteristics that make these ecosystems such potent carbon sinks?
Dr. Sasmito: Thank you. These ecosystems are distinguished by their water-saturated, oxygen-limited soils.This unique environment dramatically slows down the decomposition of organic matter,allowing them to effectively trap and store vast amounts of carbon.Peatlands and mangroves are truly unmatched in their capacity for carbon sequestration.
Unlocking the Economic Potential
your study proposes utilizing carbon credits to incentivize conservation efforts. How could this mechanism benefit both the environment and local communities?
Dr. Sasmito: By valuing carbon like othre commodities, we can create economic opportunities from conservation. Local communities can participate in carbon management, earning income while safeguarding these precious ecosystems.This can drive sustainable development, ensuring the well-being of both people and nature.
navigating the Challenges
What are some of the key obstacles hindering effective peatland and mangrove conservation in Southeast Asia?
Dr. Sasmito: One crucial challenge is balancing economic development with environmental protection. we need to prioritize sustainable land-use practices that minimize carbon losses and value the long-term benefits of these ecosystems. Strengthening regulations and enforcement to combat illegal land clearing and deforestation is also paramount.
A Call to Action
What message would you like to convey to policymakers, businesses, and individuals about the urgent need to protect Southeast Asia’s peatlands and mangroves?
Dr. Sasmito: these ecosystems aren’t just carbon sinks; they are vital for biodiversity, coastal protection, and the livelihoods of millions. Failure to protect them will have devastating consequences for the region and the world. We must act now to ensure a sustainable future by prioritizing conservation, implementing effective policies, and supporting community-based solutions.
