Bringing together world-class experts from science, policy and practice to highlight and debate the importance of peatlands from an ecological, social and economic perspective, this book focuses on how peatland restoration can foster climate change by: We would like to show you a description here but the site won’t allow Size: 1MB.

Globally, peatland drainage is responsible for 5% of human-derived CO2 emissions; drainage also increases the risk of fire, with associated environmental and socio-economic costs, and of flooding, through the process of (peat)land subsidence.

The first step in restoration of drained peatlands is to undertake a survey to determine the slope of the drains on the peatland.

This is called levelling the drains. A professional survey team will use electronic equipment. Depending on the availability of both resources and time, drains can be levelled using three metre sticks and a spirit level. Introduction.

Peatlands have been recognised as the largest carbon sink among other terrestrial ecosystems on earth, but their proper management is still problematic (Goldstein, ).A key issue is that drainage of peatlands, including for agricultural uses, evokes an irreversible process of soil subsidence leading to substantial CO2 emissions (Wösten et al., Cited by: 3.

of grazing and trampling from grazing livestock (sheep, cattle and deer) can have adverse effects on the peatland ecosystem. Research evidence suggests that blanket bog vegetation can sustain wild and/or domestic herbivore at relatively low stocking rates (equivalent to around sheep per ha or 1 sheep to the acre).File Size: KB.

Drainage ditches were installed. The outcome is a fundamental change in the vegetation and ecology of the peatland. Due to the effect of fertilisation, the natural peatland plants which have adapted to growing in nutrient poor conditions, die out quickly and are replaced by more vigorous Peatland drainage and improvement program book such as Moor Grass (Molinia caerulea).

The policy brief launched today by Wetlands International and Tropenbos International builds on the new scientific findings and provides a thorough analysis of the sustainability and impacts of peatland drainage. It calls upon government and responsible industry to recognize the threat of peatland subsidence, and plan timely action to phase-out drainage.

•Peatland hydrology measurements often difficult to carry out and there is still a lack of research on the topic •Peatland hydrology often complex where different upland processes, channel controls, and interactions with surface and groundwater are present •Drainage changes soil properties and flow patterns.

Peatland degradation & conversion. Out of 27 million hectares of South-eas Asian peatland, 12 million hectares (45%) are currently deforested and mostly drained. Peatlands are drained to enable forestry. After deforestation, drainage is in many areas intensified to establish large scale plantations (oil palm, acacia wood, etcetera).

Peatland area in Indonesia was about million ha spread out in Sumatra million ha (43 %), in Kalimantan million ha (32 %), and in Papua islands million ha (25 %). Hillman, G. R., Johnson, J. & Takyi, S. in Peatland Drainage and Improvement Program (Phase 2): Controlling Water Table Levels to Enhance Tree Establishment and Growth, Canada-Alberta Cited by:   Peatland area in Indonesia ranks first in the world for tropical peatland and ranks fourth after Canada, Russia, and the USA for general peatland area.

Tropical peatland covers about 10%–12% of the world’s total peatland area, though it stores about Gt C (Page and Rieley, ) or about one-third from the total carbon storage in peatland.

The good news is that if we block drainage canals, peatlands can be partly restored by preventing water levels from declining further. Planting native plants in degraded areas can also help by. Restoration aims at reversing the trend of habitat degradation, the major threat to biodiversity.

In Finland, more than half of the original peatland area has been drained, and during recent years, restoration of some of the drained peatlands has been accomplished. Short-term effects of the restoration on peatland hydrology, chemistry and vegetation are promising but Cited by: 9.

Many European countries have witnessed vast amounts of artificial peatland drainage including The Netherlands, Finland, Russia, Ireland and the UK. In Ireland drainage of peats and gleys has been reported since (Common, ; Wilcock, ).

Most of the Irish peat drainage was associated with the aim of reducing flooding butFile Size: KB. The study sites were drained during the s and s, with ditch spacing ranging from 30 to 50 m.

The drainage networks at each study site covered typically about 60% of the total peatland area. To keep the drainage networks fully functional, the drainage networks at some of the study sites have been cleared since the by: consequences of drainage, climate, groundwater use, or land uses • Drainage can reduce water input which can result in peat decay and wetland dissapearance • Peatland are often aquitards which control groundwater discharge at discharge boundaries!!.

• Land use can increase nutrient inputs to wetlands. Large areas of Indonesian peatlands have been converted for agricultural and plantation forest purposes.

This requires draining with associated CO2 emissions and fire risks. In order to identify alternative management regimes for peatlands, it is important to understand the sustainability of different peatland uses as well as the economic benefits peatlands supply Cited by: 6.

Drainage improvements may help one area but create new problems in another. Whenever drainage improvements are considered as a flood mitigation measure, the effects upstream and downstream from the proposed improvements need to be considered.

Peat (/ p iː t /), also known as turf (/ t ɜːr f /), is an accumulation of partially decayed vegetation or organic is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet, because peatland plants capture CO 2 naturally released from the peat, maintaining an equilibrium.

If functionality is being added to the land and the expenditures have a useful life, record them in a separate Land Improvements account. Examples of land improvements are: Drainage and irrigation systems.

Parking lots and walkways. A special item is the ongoing cost of landscaping. This is a period cost, not a fixed asset, and so should be. Peatlands have been subject to artificial drainage for centuries. This drainage has been in response to agricultural demand, forestry, horticultural and energy properties of peat and alleviation of flood risk.

However, the are several environmental problems associated with drainage of peatlands. This paper describes the nature of these problems and examines the .Tropical forests and peatlands provide important ecological, climate and socio‐economic benefits from the local to the global scale. However, these ecosystems and their associated benefits are threatened by anthropogenic activities, including agricultural conversion, timber harvesting, peatland drainage and associated by: 2."Stopping the conversion of peatland in Indonesia is a huge win in the fight against climate change", said Andrew Steer, President & CEO, World Resources Institute.

"Indonesia’s leaders have a unique opportunity to slow the country’s emissions from the conservation and restoration of peatland.
