    Acid Discharge from the Tropical Peat Swamp Forest and Its Impact on Local People – a Review

Sulphuric acid contaminates soil and river water and then acidifies the environment. Soil chemical and limnological studies in peat swamp forest in Central Kalimantan showed that sulphuric acid loading from acid sulphate soil occurred widely in the coastal region ranging from the river mouth up to 150 km from the coast. The amount of sulphuric acid discharged to freshwater systems was much higher in the rainy season than in the dry season. By holding interviews with local inhabitants on the source of drinking water for inhabitants in polluted areas this was significantly different between dry and rainy seasons. During the rainy season, river and canal water in polluted areas is not available for drinking, and at this time people avoid using river water for drinking. This paper reviews our limnological and biogeochemical studies on acidification of peat by sulphuric acid, discharging process of sulphuric acid to freshwater system, and impact of sulphuric acid pollution on local inhabitants. Key index words : acid sulphate soil, freshwater ecosystem, peat swamp forest, tropical peat, water resource Distribution of pyrite and its impact on Sulphuric acid discharge from acid peat acidification sulphate soil to freshwater ecosystems Pyrite (FeS 2) is formed in a reducing environment, e.g.

Centre-Ville, Montréal, Québec, Canada 3current address: Geography, College of Life and Environmental Sciences, University of Exeter, UK _______________________________________________________________________________________ SUMMARY Peatlands have been widely studied in terms of their ecohydrology, carbon dynamics, ecosystem services and palaeoenvironmental archives. However, several assumptions are frequently made about peatlands in the academic literature, practitioner reports and the popular media which are either ambiguous or in some cases incorrect. Here we discuss the following ten common assumptions about peatlands: 1. the northern peatland carbon store will shrink under a warming climate; 2. peatlands are fragile ecosystems; 3. wet peatlands have greater rates of net carbon accumulation; 4. different rules apply to tropical peatlands; 5. peat is a single soil type; 6. peatlands behave like sponges; 7. Sphagnum is the main ‘ecosystem engineer’ in peatlands; 8. a single core provides a representative palaeo-archive from a peatland; 9. water-table reconstructions from peatlands provide direct records of past climate change; and 10. restoration of peatlands results in the re-establishment of their carbon sink function. In each case we consider the evidence supporting the assumption and, where appropriate, identify its shortcomings or ways in which it may be misleading.

In January and February, water and in the dry season water is slowly fishes migrate into the waters in the peat released (compare Figure 3). forest for mating and breeding. During this Figure 1. Fishing in a peat swamp forest season fishermen have relatively little catch since most fishes are in the shallow inland waters far inside the peat forest. Fishers using these artificial ponds, called beje, take advantage of fluctuations in the movement of water or overflow of river water during the rainy season from November to March to trap the fish in artificial ponds or special containers. Fish come into the beje by © FAO/TECA themselves since they follow the water flow from the river to the peatland.

    Glossary Ablation Till: Till Carried on Or Near the Surface of a Glacial Ice Column and Let Down As the Glacier Melted and Retreated

    Glossary ablation till: till carried on or near the surface of a glacial ice column and let down as the glacier melted and retreated. alluvium: any mineral or detrital sediment that is transported and deposited by the flowing water of a river or stream. Riverbeds, floodplains, and deltas are all made up of alluvium. backswamp: low-lying wet areas on river floodplains, located away from the active river channel. basal till: till carried in the base of a glacial ice column and deposited under the glacier. Basal till is therefore very dense and typically forms a layer that impedes drainage. biological diversity (biodiversity): the complexity of all life at all its levels of organization, including genetic variability within species, species and species interac- tions, ecological processes, and the distribution of species and natural communities across the landscape. bog: an acidic, peat-accumulating wetland that is isolated from mineral-rich water sources by deep peat accumulation and therefore receives most of its water and nutri- ents from precipitation. Bogs are dominated by sphagnum moss and heath family shrubs. boreal forest: a circumpolar band of northern forests bordered to the north by open tundra and to the south by more transitional forests. Boreal forests are characterized by species of pine, spruce, fir, tamarack, birch, and poplar that are adapted to the extreme cold of this region. bryophyte: a division of plants including the mosses, liverworts, and hornworts. calciphile: a plant that thrives in calcium-rich soils. circumneutral: having a pH near 7.0 and therefore neither strongly acidic nor basic. cliff: an exposed, steep face of rock.
  • A-414 History of Tropical Peatland in Southeast Asia

    A-414 History of Tropical Peatland in Southeast Asia

    15TH INTERNATIONAL PEAT CONGRESS 2016 Abstract No: A-414 HISTORY OF TROPICAL PEATLAND IN SOUTHEAST ASIA Furukawa Hisao Kyoto University, Japan * Corresponding author: [email protected] SUMMARY Geohistory of tropical peatlands in Southeast Asia and a historical retrospect of the exploitation are presented. Keywords: Age, stratigraphy, early and modern ways of exploitation. INTRODUCTION Coastal plains of the Malay Peninsula, Sumatra and Borneo bordering the Sunda Sea were, and still are partly, the realm of swamp forests which included mangrove at seaward outskirts, freshwater swamp forests in the tidal zone, and peat swamp forests inland. Under natural conditions, the ground surface is covered by tropical woody peat layers of varying thickness. These peatlands emerged through the Holocene submersion of the vast and flat terrains at the periphery of the former Sunda Land, and the productive tropical rain forests which expanded over the region. The tropical peatlands inhabited only by mammals, apes, birds and reptiles, remained miasmic for long periods against human interferences because of dense forests, high humidity, numberless mosquitoes, often submerged and bumpy ground surface. Now amidst the worldwide industrialism, they are swiftly changing into one of the important agro-industrial bases, and no one cannot deny that industrialism is a powerful engine to make a people richer and more free. On the other hand, we have seen negative effects of industrialism so often. London was famous for its smog by the mid 20th century. Japan in the 1960s to 1970s was an emporium with so many kinds of environmental pollution and induced diseases. These issues were met, and even now are met through dialogs, scientific studies and legislative measures supported by our own accord.

To earlier start a better environmental policy for conservation of nature of the tropical peat swamp area is one of the preferential global issues. This study aimed at 1) clarifying the state of the tropical peat swamp area in terms of the areas of each land cover categories, and 2) locating the regions where environment have been severely damaged or lands have been extensively developed. Some digital environmental data such as GeoCover, GeoCover LC, SRTM, digital soil maps and so on were analyzed to estimate land cover maps of fine scale around 2000 region by region. As a result of this analysis, following characteristic on the land cover pattern in the Southeast Asia are clarified.
