OuTrop’s friend and colleague Dr. Sam Moore has just had his research published in Nature, which he completed in Sabangau. OuTrop are very excited to have such vital swamp research in the public eye!..
Sam, lead author and former Open University PhD student conducted extensive research in the water OuTrop know so well… “We measured carbon losses in channels draining intact and deforested peatlands, and found it is 50 per cent higher from deforested swamps, compared to intact swamps. Dissolved organic carbon released from intact swamps mainly comes from fresh plant material, but carbon from the deforested swamps is much older – centuries to millennia – and comes from deep within the peat column.”

Tropical peatlands, with their high water tables and low decomposition rates, form vast stores of organic carbon tens of metres thick. Most of it is found in Indonesia, where the natural swamp forests (also home to endangered animal species such as orangutans) are increasingly being destroyed by deforestation, drainage and fire, to make way for agriculture, in particular oil palm for biofuels and food. All these processes remove the carbon from deep within their peat soils, with consequences for the release of carbon dioxide to the atmosphere.

Deforestation of Asian peat swamps is an important source of carbon dioxide emissions globally. This message need to be widely and effectively communicated now, while some of the forests can still be saved. Carbon dating shows that the additional carbon lost from deforested swamps comes from peat which had been securely stored for thousands of years. Carbon lost from the drainage systems of deforested and drained peatlands is often not considered in ecosystem exchange carbon budgets, but the research team found it increased the estimated total carbon loss by 22 per cent. Changes in the water cycle seem to be the principal driver of this increase in carbon loss. Much of the water falling as rain would normally leave the ecosystem through transpiration in vegetation, but deforestation forces it to leave through the peat, where it dissolves fossil carbon on its way.

Dr Vincent Gauci, Senior Lecturer in Earth Systems and Ecosystem Science at The Open University, and corresponding author said: “Essentially, ancient carbon is being dissolved out of Asian peatlands as they are increasingly being turned over to agriculture to meet global demands for food and biofuels. The destruction of the Asian peat swamps is a globally significant environmental disaster, but unlike deforestation of the Amazon, few people know that it is happening”.
These results increase the urgency for protecting these ecosystems from ongoing destruction for oil palm and other uses. We hope OuTrop can help in this process in the years to come.
