This document summarizes information about global and UK peatland distribution and characteristics. It notes that peatlands cover 3% of the world's land but store over 30% of global soil carbon. In the UK, peatlands store 20 times more carbon than forests. The document also reviews peatland biodiversity, history, economic importance, and current damaged state. It identifies key threats like drainage, afforestation, overgrazing, and fire. Finally, it outlines objectives and results of a peatland restoration partnership in the UK aimed at improving carbon storage, biodiversity, water quality, and reversing peatland degradation.
Environmental threats and Land Reclamation on underground mining of Gem,graph...Pabasara Gunawardane
Removal of valuable minerals from the earth by taking both people and equipment into depths from the earth’s surface is called underground mining.Unsupported openings, Supported openings and Caving methods are the three methods of underground mining. Main methods in Underground mining are drift mining, slope mining, shaft mining, borehole process and hard rock mining.Contamination of rivers, lakes and ground water, alteration of surface and ground water flow, erosion and instability, loss of soil, material contamination, improper sanitation, increased dust, loss of faunal and floral habitats, over use of timber resources and destruction of forests and savannah are the general environmental threats of mining.
Gem mining methods range from digging deep mines and adrift to shallow open mining and river bed mining. In Sri Lanka traditional gem mining is mainly found in Balangoda, Ratnapura, Opanayake, Deniyaya, Rakwana, Elahera and Matale areas. Legislation to minimise environmental damage caused by gem mining is included within the 1971 Act drawn up by the NGJA, reinforced by the Mines and Minerals Act of 1992. Damage to vegetation cover, plantations and paddy fields, damage to land and geomorphology, man-made structures, to streams and river banks, sedimentation and water pollution, damage to fauna, alteration of surface and ground water flow and adverse environmental health conditions are some threats of gem mining.
Graphite and gold mining also have a severe impact on the environment. Especially the impacts are affecting on soil and water.
Backfilling of mined sites, seeding with grasses, tree planting at backfilled sites with native species, shaping and contouring of spoil piles and replacement of top soil are some mitigatory measures to the land reclamation after the mining of gold, gem and graphite.

A Baseline Assessment of Soil Organic Carbon in the Mangroves of the Bakassi ...ijtsrd
The mangrove soils as one of the global soil types is a major carbon store that helps to curb the rising global temperatures. This is not unconnected to their high carbon storing and sequestration potentials of the peat soils. The conclusion is characterized by some knowledge gaps on the actual carbon stock and sequestration potentials of some mangroves soils on the Central African Sub regional landscape. Some of these areas are the Bakassi mangroves in the South West Cameroon. Cross border conflicts, piracy and over exploitation have rendered the sourcing of appropriate data on its carbon stock and sequestration potentials difficult. In strive to bridge this knowledge gap, this work carried out baseline assessments of the carbon stock and sequestration rate of this peat soil. To achieve the study objectives, stratified random opportunistic sampling using an inventory design based on five forest canopy height classes, with collection of peat soils using a soil auger to different depth for laboratory analysis was done. Soils Organic Carbon stocks were estimated from soils to a depth of 100cm and determined using chromic acid digestion and spectrophotometric analysis. Parameters determined were bulk density and percentage carbon. Results showed that soil carbon stock density ranged from 705.8 Mg ha to 546.2 Mg ha .

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

1.
2. Global Distribution of Peatlands
Approximately 4 million km2
175 countries from tropics to poles
3% of the world’s land area
3. UK Distribution of Peatlands
Peatlands occur in a number
of different forms in the UK:
fens, wet woodland and bogs
92% of the peatland in the UK
occurs as blanket and raised
bogs
The UK has about 13% of the
world’s blanket bog
4. Carbon storage & sink
Peatlands cover just 3% of the world’s land surface but store more
than 30% of the total global soil carbon
A loss of just 1.6% of the global peat store equates to the total
annual global anthropogenic greenhouse gas emissions
In the UK peatlands store 3 200 million tonnes of carbon, 20 times
than that of UK forests
Semi-natural, intact bogs may remove 30-70 tonnes of carbon per
km2 per year
A loss of just 5% of the UK peat store equates to the total annual UK
anthropogenic greenhouse gas emissions
5. Biodiversity
Largest area of semi-natural habitat in the UK containing 16 NVC
plant communities
One of the most ancient and unique habitats in Europe dating back
thousands of years (designated as SAC)
Supports a unique, rare and threatened range of specialised species
adapted to waterlogged, nutrient-poor conditions such as sundews
and Sphagnum
Internationally important bird assemblages such as golden plover,
dunlin, merlin & hen harrier (designated as SPA)
6. History
Preserved pollen and partially decomposed plant remains enables
reconstruction of vegetation and land management history.
Record of past atmospheric pollution levels
Record of past events – eg volcanic eruptions
Archaeological artefacts
7. Economy
As major tourist attractions peatland bring the tourist pound into
remote areas supporting accommodation providers and local
communites
Management of peatlands for grouse (or deer stalking in Scotland)
provides employment opportunities for keepers and other sporting
managers
Peatlands are an integral part of the extensive sheep farming
systems of the UK uplands
In some areas of the UK peat is still exploited as a fuel
source
8. Current state of peatlands
Less than 20% of blanket bog in UK is in a natural or near-natural
condition
Majority of UK peatlands are no longer peat forming
16% severely eroded, 10% afforested, 11% affected by past peat-
cutting, 40% modified or destroyed by conversion to agriculture
Now emitting 3.7million tonnes of CO2 equivalents per year >
average annual emissions of Leeds, Edinburgh and Cardiff.
Only 58% of internationally designated blanket bog is in favourable
condition. Of the rest only 15% is recovering
Over last 30 years amount of dissolved organic carbon (brown
colour) in water draining peatlands has doubled which has to be
taken out by water companies
9. Key damaging drivers
Large areas drained with ditches (grips) through agricultural
subsidies. No longer funded but still flowing and eroding
10% of UK peatlands afforested. Generally requires drainage,
cultivation and fertilisation which causes peat to crack, shrink and
oxidise
Heavy grazing changes the vegetation converting from specialists to
grass dominated peatlands which begin to erode and stop peat
forming.
Fire. Wildfire and poorly-managed burns on grouse moors damages
Sphagnum and leads to conversion to heather and grasses.
Dessicated peatlands are drier and more prone to fire – a vicious
circle

12. Objectives
•Restore 35,000 (50%) of peatland by restoring 3401km (45%) of
grip/gully and re-vegetating 169ha (50%) of bare peat by March
2017
• Establish long-term sites for research into the benefits of
peatland restoration to ecosystem services by March 2013
•To use and promote best practice in all applied restoration
techniques
•To raise awareness and promote the multitude of benefits that
peatland restoration can provide
21. Gully/hag reprofiling
All gullies but especially larger ones that can’t be blocked are re-
profiled and then re-vegetated to remove source of continued erosion
22. Re-vegetating bare peat
Bare peat needs treating in several ways to get a vegetation cover to
establish
pH levels often too low for vegetation (even Sphagnum)
Wind, water and frost heave in exposed areas mean surface is
continually mobile so vegetation cannot get a hold
Vulnerable to dessiccation in dry periods
23. Cut heather brash
Transport brash to site
Spread brash to stabilise surface
Create stable root mat
Spread lime & fertiliser to support
growth for 3 yrs
3 yrs on all being well
Establish Sphagnum & other
peat formers
24. Results so far
Achievement by December 2011 Quantity
Area of land surveyed 16,542ha (48%)
Area under restoration 3283ha (10%)
Length of grips blocked 334km (13%)
Length of eroding gullies re-vegetated 40km (5%)
Area of bare peat re-vegetated 17ha (10%)
Number of peat dams installed in grips 33,000
Number of timber sediment traps installed in larger grips and 300
gullies
Number of peat depth records 20,000
Number of volunteers involved 40
27. Water quality
Blocking reduces fine particulate organic matter, suspended solids
and bed sediment leading to change back to Ephemeroptera,
Plecoptera, Trichoptera from Diptera.
Peatlands cover approximately 4million km2 3% of the world’s land area Stretching across 175 countries from the tropics to the poles
UK has 9-15% of Europe’s peatlands UK peatlands form 33% of the UK’s soils. The majority of UK peatlands are concentrated in Scotland and northern England Red/dark brown show the deeper peatland areas with mainly blanket and raised bogs Green shows the degraded shallow peaty soils again mainly in the uplands The light brown areas in East Anglia and other agricultural lowlands show wasted or cultivated peat. The peatlands in the southeast are fens
