Global Economy Threatened by Dramatic Loss of Wetlands

The alarming destruction of global wetlands could lead to economic losses of up to US$39 trillion by 2050. A recent report by the Convention on Wetlands reveals that 22% of these vital ecosystems have already disappeared since 1970 – an unprecedented loss occurring faster than in any other ecosystem.

The threats are manifold: land-use changes, pollution, agricultural expansion, invasive species, and climate change impacts are all putting pressure on wetlands. Particularly concerning is that a quarter of the remaining wetlands are already classified as degraded. In total, 411 million hectares – an area larger than Germany and France combined – have already been destroyed.

To counter this development, annual investments of $275 to $550 billion are required. While this sum may seem high, it is justified given the crucial functions of wetlands: they regulate floods, purify water, store carbon, and support fisheries and agriculture.

Ahead of the upcoming meeting of parties in Victoria Falls, Zimbabwe, it’s clear: protecting wetlands is a global challenge that requires immediate action. While Africa, Latin America, and the Caribbean are particularly affected by the deterioration, Europe and North America are also experiencing increasing losses
