UN-SEEA Ecosystem Accounting

Extent

Map of where the ecosystems are, broken down to percentage coverage.

Condition

Locate areas of high or low ecosystem condition to assess risk of degradation or targets for conservation.

Value

Tier 2 carbon stock & biodiversity indicators (ecosystem connectivity & patchiness).

Coastal ecosystems are an essential part of climate mitigation

Value

From fishing to flood protection, healthy ecosystems provide the resources and stability that fuel our industries, communities, and the planet itself.

Threat

In the past 50 years, we've lost an unprecedented amount of these ecosystems, and each year, 450 million metric tons of C02 (equivalent to 19% of total deforestation) is emitted from the destruction of coastal wetlands.
