The benefits from conserving and restoring seagrass meadows.

Image
Despite a general global trend of seagrass loss , some areas have shown abating declines or substantial recovery of seagrasses. These recoveries can often be attributed to human interventions reducing the effect of human-caused stressors . Seagrasses are critical for life underwater , but also provide wide-ranging benefits to people on land. Raising awareness about their importance for community well-being, whether through food security from fish production, improved quality of water filtered by seagrasses, protection of coasts from erosion, storms and floods, or carbon sequestration and storage will drive efforts around the world to conserve, better manage and restore these ecosystems. Ultimately, the protection and restoration of seagrass meadows will help countries achieve multiple economic, societal and nutritional objectives, aligning with and supported by policies implemented at the national, regional or global levels . For example:The benefits from conserving and restoring sea...

Focus on the key drivers of the degradation of seagrasses.

Image
Despite Seagrasses 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.

Why seagrass matters?

  The 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 ener...

Seagrass for nature and people.

Seagrass and Seagrass beds are one of the most widespread coastal habitats on the planet. They provide a range of environmental, economic and social benefits to humans, making them one of the most valuable coastal and marine ecosystems on Earth, but they are under threat. The report, Out of the Blue: The Value of Seagrasses to the Environment and to People (UNEP), provides recommendations to help restore them.

Identify gaps and develop actionable strategies for the protection and restoration of seagrass.

The First Asian Regional Dialogue on Seagrass and Dugong Conservation  brought together key experts, policymakers, and conservation practitioners to discuss innovative approaches, identify gaps, and develop actionable strategies for the protection and restoration of seagrass ecosystems and associated dugong population s. Seagrass and Dugong Conservation: From Gaps to Impactful Action. 20 - 21 February 2025.
