Wetland ecosystems have enormous potential for carbon storage — up to 20 times greater than terrestrial forest ecosystems — and maritime countries like Indonesia are starting to pay attention.

Not exact matches

The U.S. and Canadian NGO ForestEthics reports that «Canada's boreal forest (alone) stores 23 percent of the planet's terrestrial carbon - more carbon per acre than any other ecosystem on earth, including tropical forests.

Lead author Dr Mark Abrahams, from UEA's School of Environmental Sciences, said: «Understanding the impacts of subsistence hunting in tropical forests is crucial not only to safeguard the world's most biodiverse terrestrial ecosystems, but also to secure a sustainable future for forest - dependent communities.»

Tropical forests convert more carbon from the atmosphere into biomass than any other terrestrial ecosystem on Earth.

At the moment, these carbon markets only trade in credits for terrestrial ecosystems; for example, keeping a certain amount of forest intact in order to offset a ton of carbon dioxide emitted by burning fossil fuels.

«These results indicate that protection of natural habitats at a watershed level, including wetlands and forests, will increase the proportion of rare species and reduce the risk of extinction, which is much greater in aquatic than in terrestrial ecosystems,» Passy said.

Parts of the vast rain forest are as much aquatic as terrestrial ecosystems.

Cory Cleveland, a UM professor of terrestrial ecosystem ecology, said that previous research in the wet tropics — where much of global forest productivity occurs — indicates that the increased rainfall that may occur with climate change would cause declines in plant growth.

Because tropical forests like those in the Sabah have converted large quantities atmospheric carbon into organic material — and they accomplish more of this than any other terrestrial ecosystem on Earth.

The coastal ecosystems of mangroves, seagrass meadows and tidal marshes mitigate climate change by sequestering carbon dioxide (CO2) from the atmosphere and oceans at significantly higher rates, per unit area, than terrestrial forests (Figure 1).

GOAL 15 — Life on Land — Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss.

Land — Terrestrial ecosystems and land use, sustainable agriculture and food systems, mineral extraction, healthy forests, pollution, toxics and hazardous wastes

While laying out several important wild cards (expanded farming of biofuels among them), Ausubel and his co-authors see a reasonable prospect for conserving, and restoring, forests and other stressed terrestrial ecosystems even as humanity exerts an ever greater influence on the planet.

This forest plays a key role in the global carbon equation by serving as a major storehouse for terrestrial carbon — indeed, it is believed to store more carbon per hectare than any other ecosystem on Earth.

This finds stronger and solid footing in Article 5.1, which states, «Parties should take action to conserve and enhance, as appropriate, sinks and reservoirs of greenhouse gases» (i.e. «biomass, forests and oceans, and other terrestrial, coastal and marine ecosystems»).

Based on measurements of ecosystem CO2 flux, radiation absorption by plants, crop yields and a model simulating the terrestrial biosphere, a multinational team of researchers has found that during July and August 2003, 500 million tonnes of carbon escaped from the forests and fields across Europe as a result of extreme heat and drought.

The largest reservoirs of carbon on land are in the forests of the tropics and the soils of northern high latitudes, which are paradoxically, the least studied of terrestrial ecosystems, with the bulk of research effort made where most ecologists live, in the mid-latitudes.

A fifth of global human - caused carbon emissions today are absorbed by terrestrial ecosystems; this important carbon sink operates largely without human intervention, but could be increased through a concerted effort to reduce forest loss and to restore damaged ecosystems, which also co-benefits the conservation of biodiversity.

«One quarter of CO2 emissions are going to terrestrial ecosystems, but the details of those processes and how they will respond to a changing climate are inadequately understood, particularly for tropical forests,» Chambers said.

Healthy forests play a key role in global ecosystems as they contain much of the terrestrial biodiversity on the planet and act as a net sink for capturing atmospheric carbon.

This time around, the scientists tapped the vastly improved satellite imagery from Google Earth, which covered more than 210,000 dryland sites, and ground data gathered by the Terrestrial Ecosystem Research Network to carry out a new global analysis of dryland forest cover.

Amazon forests represent the world's largest terrestrial biome and potentially the tropical ecosystem most vulnerable to abrupt change in response to future climate change in concert with agricultural development (e.g., Cox et al., 2000; Lenton et al., 2008; Zelazowski et al., 2011).

This refers to that part of the framework convention itself that recognizes «common but differentiated» responsibilities between rich and poor countries, and also the need to promote the sustainable management of natural carbon sinks, including «biomass, forests and oceans as well as other terrestrial, coastal and marine ecosystems.»

But the world's land and forests are already past their carrying capacity, and terrestrial ecosystems, upon which all life depends, are crashing.
