Report: World faces up to $39 trillion of economic losses due to disappearing wetlands

According to a report released by the Convention on Wetlands on Tuesday, the destruction of wetlands around the world, which are vital for fisheries, farming and flood control could result in a loss of $39 trillion by 2050.

According to an intergovernmental report, 22% of freshwater systems, such as rivers, lakes and peat lands, and coastal marine ecosystems, including mangroves, coral reefs and coastal systems, have disappeared since the 1970s. This is the fastest rate of loss for any ecosystem.

The declines are a result of pressures such as land-use changes, pollution, agricultural expansions, invasive species and climate change impacts, including rising sea levels and drought.

Hugh Robertson is the main author of the report. He said, "The extent of the loss and degradation exceeds what we can afford not to acknowledge."

The report recommended annual investments between $275 billion and $550 billion in order to reverse threats to remaining wetlands. It also stated that current spending is a "substantial underestimate" without providing figures.

According to a report, 411 million hectares, or half a billion soccer pitches, of wetlands have been lost. A quarter of those remaining wetlands is now in a degrading state.

The economic benefits of wetlands include flood control, water purification, and carbon storage. This is important as the water levels increase and hurricanes and tropical storms intensify because of climate change.

The fishery, agriculture and cultural industries also benefit from these products.

The report is launched a week ahead of the Victoria Falls, Zimbabwe meeting of the Parties to the Convention on Wetlands. This global agreement was signed by 172 countries in 1971, with the goal of protecting the ecosystem.

The group includes China, Russia, and the United States. It is not clear if each nation will send delegates.

The report stated that the deterioration of wetlands is most acute in Africa, Latin America and the Caribbean but worsens in Europe and North America.

In Zambia, Cambodia, and China, rehabilitation projects are underway.
