The findings, published in the international journal New Phytologist, have implications for scientific understanding of how mangrove systems sequester "blue carbon" -- CO2 absorbed from the atmosphere and locked up in coastal wetlands such as mangroves.

Fiji's LEDS sets out long-term emission reductions and defines sustainable and resilient economy-wide mitigations pathways until 2050. It also addresses: sector-specific targets and measures; social, economic and environmental dimensions; education, capacity building and awareness raising; and a framework for monitoring and evaluating the LEDS. It is also among of the world's first LEDS to address the Blue Carbon Sector and the island country's mangrove ecosystems.
The LEDS also details Fiji's objective of reaching net-zero carbon emissions by 2050 across all economic sectors, and details the following potential low emission scenarios:

The programme is being developed by Marine Scotland in partnership with Scottish Natural Heritage, St Andrew's University, Glasgow University, Heriot-Watt University, Napier University, and the Scottish Association for Marine Science.
Scotland Environment Secretary Roseanna Cunningham said: "The potential role of our marine environment in tackling the greenhouse gas problem is enormous, with recent research by the University of St Andrews estimating that more carbon is captured and stored in sea lochs alone than in our terrestrial environment, such as forests and peatlands. Scottish Natural Heritage has estimated that the amount of carbon stored within Scotland's Marine Protected Areas is the equivalent of four years of Scotland's total greenhouse emissions," the Environment Secretary added.
Chair of the Blue Carbon Forum Professor John Baxter said: the "Programme will provide essential information to help inform what is required to be done to enhance and protect these key habitats into the future which is essential for the mitigation of future climate change."

According to the study, eelgrass organic carbon stocks were comparable to organic carbon stocks of tropical seagrass species, as well as mangroves, salt marshes and terrestrial ecosystems. The researchers also found that on average, eelgrass meadows stored 27.2 tons of organic carbon per hectare, although the variation between the regions was considerable
In the marine systems, the blue carbon species alone account for up to 33 pct of the total oceanic CO2 uptake. In contrast to terrestrial soils, which usually store carbon up to decades, the carbon stored in blue carbon ecosystems may persist for timescales of millennia or longer and thus, contribute significantly to climate change mitigation and alleviation of the rising atmospheric carbon dioxide concentrations. Despite the importance of these ecosystems, to date, none of them are included in the global carbon trading programmes. Alarmingly, in the past 50 years, at least one-third of the distribution area of coastal vegetated ecosystems has been lost.

The recently released long-term study offers a better understanding of how mangrove deforestation contributes to the greenhouse gas effect, one of the leading causes of global warming.
The Brazilian mangrove forest fringes the entirety of the Atlantic Coast at the mouth of the Amazon, the largest river in the world with the largest mangrove forest. Mangroves -- aka Blue Carbon -- represent 0.6 pct of all the world's tropical forests but their deforestation accounts for as much as 12 pct of GHG emissions from all tropical deforestation.
Partial funding for the study was provided by the U.S. Agency for International Development, Sustainable Wetlands Adaptation and Mitigation Program.

In total, the researchers estimated Victoria's inland wetlands had a soil carbon stock of 68 million tons, worth about $6 billion under Australia's most recent carbon price.
According to lead researcher Dr Paul Carnell, "While a lot more is known about how trees suck up and store carbon, freshwater wetlands can actually sequester 20 to 40 times more carbon than forests on dry land."
The study was funded by the Victoria Department of Environment, Land, Water and Planning.
The study, published in the journal Global Change Biology.

On land, forests capture carbon dioxide and produce oxygen. Forests release their carbon every few hundred years, due to fire, tree mortality or human harvesting. By comparison, coastal marshes maintain their carbon for thousands of years. Coastal ecosystems do the same -- but they're much better at it, according to McGill University "Blue Carbon" authority Assoc. Prof. Gail Chmurain. Coastal ecosystems can hold three to five times more carbon than the equivalent area of forest, according to a federal government report.
The financial value of blue carbon comes from its potential for carbon emission credits which the Canadian federal government is introducing.
According to government documents, "carbon stored in tidal salt marshes in the Bay of Fundy could have an estimated value of $202 million." That would equal $1 billion in 2022.
In terms of Canada's national carbon emissions strategy, blue carbon could be used as an offset to meet international targets and
coastal communities could protect or rehabilitate wetlands to generate carbon credits.

With XL Catlin's support, TNC will develop a system of credits assigning a market value to the resilience services provided by these historically under valueded cosystems. The hope behind this initiative is that, for the first time, insurance firms and other businesses will be able to offset their carbon footprint while simultaneously better underdstanding the contribution they are making to reducing coastal hazards in the world's most vulnerable coastal areas.
Coastal wetlands -- salt marshes, seagrass meadows and mangroves -- sequester billions of tonnes of "blue carbon" from the atmosphere at concentrations up to five times greater than terrestrial forests. As an increasing number of companies are purchasing carbon credits to offset their footprints, this credit will enable a valuation of the carbon sequestration and coastal resilience benefits that wetlands provide both businesses and communities.
Unlike other climate mitigation solutions coastal wetlands not only sequester carbon, they also protect coastlines by absorbing incoming wave energy and providing storm protection. Additionally, a recent study found that wetlands prevented $625 million in direct flood damages from Hurricane Sandy in the United States. As such, coastal wetlands provide both carbon sequestration and resilience services- a powerful combination in a world of changing climate.
TNC will explore different options to value the resilience services provided by coastal wetlands and to develop a credit product to support ongoing wetland conservation. One of these options could include a numeric ranking system assigning a dollar value to wetlands based on factors such as their potential for storm impact reduction, location relative to vulnerable communities, local economic activities and assets, and potential benefits from habitat restoration. The figures generated by the rankings, combined with the carbon storage capacity of a given wetland, would generate Blue Carbon Resilience Credits. These credits would then offer organizations the capacity to manage their carbon footprints whilst acting as the funding mechanism for wetland conservation, increasing coastal resilience for communities.

One hectare of seagrass, along with mangroves, has 30 - 50 times the potential of Amazonian forest in terms of [carbon] mitigation, according to study researcher and lead author Oscar Sorrano. It also has the potential to release huge amounts of carbon-dioxide back to the atmosphere -- potentially increasing the likelihood of further heatwaves by fuelling global warming.
The researchers - ranging from Australia, Spain, Malaysia, the United States and the Kingdom of Saudi Arabia - estimated the loss from the heatwave event released as much as 9 million tonnes of CO2, or the equivalent annual emissions of 800,000 homes or 1,600,000 cars.
The estimates were based on modelling releases based in-situ studies from 50 sites. (Source: Edith Cowan University, Nature Climate Change, Sydney Morning Herald, 20 Mar., 2018) Contact: Edith Cowan University, Oscar Serrano, Researcher, Paper Lead Author, +61 8 6304 0000, www.ecu.edu.au
