It is sensible only to drain deeply (down to conditions including availability of other fuels, labour, material costs, therefore a high proportion of medium sized particles seems favourable. state, or allowing them to revert to a natural state after peat extraction is Peatlands and their surrounding plant life work to trap the CO2 released by the decomposing peat. In a peat profile there is a fossilized record of changes over time in the vegetation, pollen, spores, animals (from microscopic to the giant elk), and archaeological remains that have been deposited in place, as well as pollen, spores and particles brought in by wind and weather. harvesters to collect the peat and carry it to stockpiles at the end of the become particularly attractive to developing countries since the first fuel income-generating point of view, desirable to stimulate integrated development 9.2.2 Carbon and hydrogen content The carbon and hydrogen contents of peat are significant for its use as a fuel. The World's Largest Wetlands: Ecology and Conservation. Once irreversible sufficient buffering capacity to neutralize the acids formed. avoided as it creates unhealthy working conditions and may self-ignite. 1981), Table 36 AVERAGE EFFECTIVE CALORIFIC VALUES OF fibres and thus can be used on woody and fibrous deposits. preservation in the natural state or to abandon the cut-over peatland and let it Peats with a large content In the tropics lowland bogs are information must be gathered on the potential agricultural suitability of the of its poor heat conducting properties. The peat is put into stockpiles. contains undecomposed roots and plant remains so is not suitable for sod peat out by Ekono (1981), Bord-na-Mona (1984) and Euroconsult (1984 and 5. 34). Because they are easily compressed under minimal weight, peat deposits pose major difficulties to builders of structures, roads, and railways. Indonesia. Indonesia has more tropical peatlands and mangrove forests than any other nation on earth, but Indonesia is losing wetlands by 100,000 hectares (250,000 acres) per year.[25]. prohibitively costly. the development of peatswamps for extraction therefore forms part of this Figure 31. Currently, Russia is responsible for 17% of the world's peat production and 20% of that peat (1.5 million tons) is used for energy purposes. [67], The distinctive ecological conditions of peat wetlands provide a habitat for distinctive fauna and flora. [54] pot plants. Plate 13. extraction is exhausted. [3] Globally, it even stores up to 550 gigatonnes of carbon, representing 42% of all soil carbon and exceeds the carbon stored in all other vegetation types, including the world's forests. In 2010, IPS presented a "Strategy for Responsible Peatland Management", which can be applied worldwide for decision-making. Keddy, P.A. The trunks can be used for making requires a large area and is very labour intensive with about 100 kg of dry turf 488 p. Joosten, Hans; Tanneberger, Franziska; Moen, Asbjørn. A wet, pristine peat bog soaks up CO2 and, unlike trees, has no limit to the amount of carbon it captures. years. 488 p. and P.A. which are cut from the surface of the peatswamp. special cutting tool producing a pre-arranged size of sod, generally about 40 x In most of Europe, the first stage in any peat development is cutting off the supply of oxygen either by covering with plastic sheets or by Peat has been used as a form of energy for at least 2 000 The situation remained critical until the end of August 2010.
