Peat and peatland evaluation of the Longlac-Nakina area
|The Physical Object|
This paper derives the distribution of peatland in Europe as the extent of peat and peat-topped soils indicated by soil databases. The data sources . Peat fire and the consequent degradation of peatland have had significant negative environmental and economic consequences at national and global levels. A green economy transition path is seen as a socioeconomic solution to address peat degradation. Swamp agriculture, better known as paludiculture, is a green economy action holding promise. .
Peatland represents quite significant phenomenon in the headstream areas of Czech rivers. Considering the fact that these areas are crucial for streamflow generation process, it is very important to study the mechanism of runoff formation in a peatland and its hydrological function. Natural runoff process is affected by man already by its birth, thus in headwaters where Author: Jan Kocum, Bohumír Janský, Lukáš Vlček, Tomáš Doležal.  Ground penetrating radar (GPR) was used to determine peat basin geometry and the spatial distribution of free‐phase biogenic gasses in two separate units of a northern peatland (Central and Southern Unit of Caribou Bog, Maine). The Central Unit is characterized by a deep basin structure (15 m maximum depth) and a raised (eccentric) bog topographic profile (up to 2 m Cited by:
Conclusions. Peatland development is controlled by both autogenic and allogenic factors. The processes of peat (sediment) accumulation and acidification by Sphagnum result in hydroseral successions towards drier and more oligotrophic conditions. Secondary pattern development is also largely initiated by local biotic factors, with the exception of permafrost by: The GWT is the principal parameter to evaluate the peat ecosystem, because high GWT prohibits peatland from being degraded by microorganisms and fire. If GWT comes to low by mainly peatland drainage, then oxygen comes into peat, and oxidizes peat by microorganisms and fire. Thus, the GWT map is necessary for peatland management and evaluation.

Contents include: * Peat Author: Dan Charman. Usup et al. () found that the burning or fire of peat charcoal was more violent than the burning of volatile matter in peat soil due to the presence of large amounts of lignin in the peat soil. Peatland fires do not only turn peatlands from C sinks to C sources, they also release large amounts of other gases and particles to the atmosphere Cited by: 6.
Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland.
Peatlands form part of the iconic landscape of Ireland and account for nearly a quarter of the land area. Raised bogs, blanket bogs and fens are Ireland’s last great area of wilderness, hovering between land and water, providing unusual habitats for its unique and specialist flora and fauna.
The peat layer in arctic peatlands is not thick, and only in rare cases does the peat exceed 4 – 6 m in depth (V asilchuk et al. ; Peteet et al. ; Andreev et al. ; Pitkanen et al. And the peatland areas in Indonesia covers 10% of the total land area, or about 20 million ha.
According Wahyunto () the peatlands in Kalimantan, based. A peatland is an area with or without vegetation with a naturally accumulated peat layer at the surface. The term “mire” describes a wetland ecosystem where peat accumulates (Moore and Bellamy, ) or a peatland where peat is currently being formed (Joosten, ), although it is difficult to know if peat is still forming or by: 6.
Mire is peatland where peat is being formed (Josten and Clark ). Bogs and fens are a type of mire based on its shape, landscape, and land use potential, i.e. nutrient contents (Joosten peatland types although Sphagnum-dominated peatlands are the most studied compared to other peatland types.
The re-dox potential is decisive for many biogeochemical processes in the peat, and this is largely governed by the position of the water table.

Contents 1. Characteristics of peat and peatland 2. About this book. Tropical Peatland Ecosystems is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon-water flux/storage, biodiversity and peatland management in tropical.
In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation.
Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result. technology of peat. Other books that discussed peat properties include: P.D. Moore and D.J.
Bellamy’s Peatland, nov’s Peat Deposit, Sakakuchi’s Geography of Peatland, etc. At present, research on peat properties mainly discusses physical and chemical assessment of peat.
Due to an awareness of peatlands as a diminishing resource, peatland conservation and rehabilitation has become an important study area.
Peatlands and Environmental Change offers a new approach by considering peatlands as a whole ecosystem, and thereby provides a better understanding of the importance and the consequences of the functioning of peatlands. The mapped extent of potential peatland is much more extensive than the sampled area, raising questions about whether all the potential areas really harbour peat, and, if so, how old and deep the Cited by: 2.

To analyse the trends in Indonesian peatland-use, we only considered peatland with the peat depth of at least 50 cm (Krisnawati et al.
) with an estimation of the total area around million hectares (Ritung et al. ), although there is still uncertainty on the exact peat area and by: 6.
The area of peatland within palm oil concessions, however, is much larger, and many are unplanted but degraded. Oil palm cultivation has negative effects on peatlands Cultivation of oil palm on peat comes with certain challenges, like high CO2 emissions, peat soil subsidence, consequent flooding, and productivity loss.
