Along with their water and soil purification capabilities, it can be understood why it is vital to preserve and restore these wetlands worldwide from the negative impacts of sea level rise.
Coastal tidal wetlands, such as saltmarsh and mangrove wetlands, can be found in the tidal zone between the land and ocean. These vegetated intertidal ecosystems are valuable ecological environments that serve as important habitat for wildlife; in addition to providing numerous ecosystem benefits for humans. Globally, 50% of these wetlands have been disturbed or damaged by human impact since 1900 and projections indicate up to 30% of current global wetlands could be lost due to sea level rise by 2100.
The United Nations declared 2021-2030, the Decade on Ecosystem Restoration calling upon nations and governments to take action to restore damaged ecosystems. To support this important initiative UNSW EcoEng researchers from the Water Research Laboratory have developed a sustainable solution that demonstrates the ability to preserve existing coastal wetlands from sea level rise threat and restore wetlands already influenced by human intervention. We call our solution the “Tidal Replicate Method”!
