Acid Discharge from the Tropical Peat Swamp Forest and Its Impact on Local People – a Review
TROPICAL PEATLANDS Acid discharge from the tropical peat swamp forest and its impact on local people – a review Akira Haraguchi 1, Liwat Yulintine 2, Linda Wulandari 2, Tris Liana 2, Sepmiarna Welsiana 3 1 The University of Kitakyushu, Hibikino 1-1, Wakamatsu, Kitakyushu 808-0135, Japan Phone: +81 93 695 3291, Fax: +81 93 695 3383, E-mail: [email protected] 2 The University of Palangkaraya, Palangkaraya, Central Kalimantan, Indonesia 3 Marine and Fishery Department, Katingan Regency, Central Kalimantan, Indonesia Summary After destruction of the peat layer over pyrite-containing sediment, pyrite is oxidized and sulphuric acid is produced. 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. -

Questioning Ten Common Assumptions About Peatlands

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. -

Transitions for the Delta Economy
Transitions for the Delta Economy January 2012 Josué Medellín-Azuara, Ellen Hanak, Richard Howitt, and Jay Lund with research support from Molly Ferrell, Katherine Kramer, Michelle Lent, Davin Reed, and Elizabeth Stryjewski Supported with funding from the Watershed Sciences Center, University of California, Davis Summary The Sacramento-San Joaquin Delta consists of some 737,000 acres of low-lying lands and channels at the confluence of the Sacramento and San Joaquin Rivers (Figure S1). This region lies at the very heart of California’s water policy debates, transporting vast flows of water from northern and eastern California to farming and population centers in the western and southern parts of the state. This critical water supply system is threatened by the likelihood that a large earthquake or other natural disaster could inflict catastrophic damage on its fragile levees, sending salt water toward the pumps at its southern edge. In another area of concern, water exports are currently under restriction while regulators and the courts seek to improve conditions for imperiled native fish. Leading policy proposals to address these issues include improvements in land and water management to benefit native species, and the development of a “dual conveyance” system for water exports, in which a new seismically resistant canal or tunnel would convey a portion of water supplies under or around the Delta instead of through the Delta’s channels. This focus on the Delta has caused considerable concern within the Delta itself, where residents and local governments have worried that changes in water supply and environmental management could harm the region’s economy and residents. -
Beje Aquaculture and Inland Fishery in Tropical Peatland of Indonesia

Peatlands are their vegetation on the top of it. That is why in the main resources area. They traditionally catch Figure 2, the peatland is higher than the level fishes and reptiles, and collect fuel wood and of the river. In the rainy season it collects grass in peatlands. 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. -

Building Communities – Economics & Ethnicity
Building Communities – Economics & Ethnicity Jennifer Helzer, California State University, Stanislaus Helzer, 1 Delta Protection Commission Delta Narratives (Revision Final) June 11, 2015 Building Communities – Economics & Ethnicity Jennifer Helzer, California State University, Stanislaus INTRODUCTION Approaching the Delta from the east, off of Interstate 5, the hurried and harried pace of life gives way to a gradual western sloping landscape of manicured fields. As the morning fog burns away, glimpses of old barns, field equipment, and neatly stacked fruit crates appear alongside the road. As one approaches town, heavy‐duty pick‐up trucks meet at the four‐way stop with their driver motioning for visitors to take the right‐of‐way. The post office and local coffee shop buzz with morning routines. A tour through the Delta carries visitors along levee roads, across iconic bridges and into culturally rich historic towns. Orchards and row crops expand from levee roads; and farmsteads and stately homes exist alongside ethnic heritage landscapes and new commercial developments. The communities of the Delta are places of the present and the past that are stitched together by a network of railroads, canals and levees, and by the open spaces that link them together. These are the first impressions of the Delta as a place and the start of many questions. What is the meaning of this place, who made this place and how has it changed through time? In the 1850s, powerful economic, political and social forces precipitated momentous change in the Delta region of California: 1) the California Gold Rush, 2) levee construction and agricultural development, and 3) the migration and settlement of domestic, European and Asian cultural groups. -
