HEALTHY SEAGRASS, HEALTHY PLANET
In May 2022, the General Assembly adopted A/RES/76/265 proclaiming 1 March as World Seagrass Day. The resolution highlights the urgent need to raise awareness at all levels and to promote and facilitate actions for the conservation of seagrasses in order to contribute to their health and development, bearing in mind that enhancing ecosystem services and functions is important for the achievement of the Sustainable Development Goals. Seagrasses are marine flowering plants that are found in shallow waters in many parts of the world, from the tropics to the Arctic circle. They form extensive underwater meadows, creating complex, highly productive and biologically rich habitats.
Covering only 0.1% of the ocean floor, these seagrass meadows provide food and shelter to thousands of species of fish, seahorses, turtles, etc. and sustain some of the world’s largest fisheries. They improve water quality by filtering, cycling and storing nutrients and pollutants, reducing contamination in seafood. Highly efficient carbon sinks, they can store up to 18% of the world’s oceanic carbon, making them a powerful nature-based solutions to tackle climate change impacts. Because they buffer ocean acidification, they contribute to the resilience of the most vulnerable ecosystems and species, such as coral reefs. And to the coastal populations, they act as the first line of defense along coasts by reducing wave energy, protecting people from the increasing risk of floods and storms.
Despite its important contribution to sustainable development and climate change mitigation and adaptation, this core component of marine biodiversity is in danger and only about a quarter of all meadows fall within marine protected areas. Seagrasses have been declining globally since the 1930s, with the most recent census estimating that 7% of this key marine habitat is being lost worldwide per year. It was recently noted that 21% of seagrass species are categorized as Near Threatened, Vulnerable and Endangered Species under the International Union for Conservation of Nature Red List of Threatened Species. The combined pressures of coastal development, pollution, including land-based run-off, climate change, dredging and unregulated fishing and boating activities are key drivers of the degradation of seagrasses and their associated ecosystems.
