Sentences with phrase «peat decomposition»

While oil palm can be grown sustainably, this is rarely the case in Indonesia, where Wetlands International estimates that production of one metric ton of palm oil will result in an average emission of 20 tons of carbon dioxide from peat decomposition alone, not including emissions resulting from production or combustion.

Forest loss and degradation and peat decomposition and fires are behind average annual carbon emissions equivalent to 122 percent of the Netherlands total annual emissions, 58 percent of Australia's annual emissions, 39 percent of annual UK emissions and 26 percent of annual German emissions.

Substantial N2O emissions from peat decomposition and N fertilization in an oil palm plantation exacerbated by hotspots

«Combined with a literature review, the results showed that high N2O emissions from peat decomposition in the tropics tend to be common; which is in contrast with most recent IPCC [Intergovernmental Panel on Climate Change] emission factors,» she says.

The low apparent sensitivity of peat decomposition to warming has important implications for the future of the peatlands, as warming is unlikely to result in widespread carbon loss.

This indicates oxygen exposure time was the primary control on peat decomposition, while temperature was of secondary importance.

The scientists warn that climate change threatens these habitats, not only from rising temperatures increasing peat decomposition, but also via altered rainfall patterns — with summer droughts drastically affecting the blanket bog hydrology.

Two principal techniques were used to reconstruct past climates over the past 3000 years: at close intervals throughout a vertical column of peat, the researchers investigated the degree of peat decomposition, which is directly related to climate, and also examined the peat matrix to reveal the changing amounts of different plants that previously grew on the bog.

Not exact matches

Almost 20 years ago, she buried small bags of peat in a Canadian bog to study their decomposition.

Hergoualc» h explains that in their natural state, peatlands are flooded for part of the year, leading to a slow decomposition of organic matter deposited by plants, and eventual accumulation of carbon in the form of peat.

peat unconsolidated soil material consisting largely of partially decomposed organic matter accumulated under conditions of excess moisture or other conditions that decrease decomposition rates

The study included carbon dioxide emissions from burning fossil fuels and producing chemicals and cement but excluded emissions from activities like deforestation and logging, forest and peat fires, the decay of biomass after burning and decomposition of organic carbon in drained peat soils.

Emissions of CO2 were highest from peat incubated in the localized permafrost feature, suggesting that slow organic matter accumulation rates are due, at least in part, to rapid decomposition in surface permafrost peat.
