International Day for the Conservation of the Mangrove Ecosystem

International Day for the Conservation of the Mangrove Ecosystem is celebrated annually on July 26. In 2026, this date falls on a Sunday. This United Nations Educational, Scientific and Cultural Organization (UNESCO) holiday aims to raise awareness about the importance of mangrove ecosystems as unique, special, and vulnerable environments that provide critical services to both nature and people. Mangroves are rare, spectacular, and prolific ecosystems found along sheltered coastlines in tropical and subtropical regions, where they support rich biodiversity, protect shorelines, and act as powerful carbon sinks.

History of International Day for the Conservation of the Mangrove Ecosystem

On November 6, 2015, during the 38th session of the General Conference in Paris, UNESCO adopted resolution 38C/66 to officially declare July 26 of each year as the International Day for the Conservation of the Mangrove Ecosystem, responding to a request from Ecuador. The date was chosen to honor Greenpeace activist Hayhow Daniel Nanoto, who tragically died from a heart attack on July 26, 1998, during a massive protest to restore mangrove wetlands in Muisne, Ecuador. The first official World Mangrove Day was held on July 26, 2016.

Since 2015, various parties, non-governmental organizations, and interested stakeholders have celebrated this day with outreach activities worldwide on July 26 each year. These events raise and spread awareness of the need for international cooperation to conserve mangrove ecosystems and promote innovative solutions for their sustainable management, conservation, and uses. Unlike many other international days, there is no annual theme for this observance.

Why is International Day for the Conservation of the Mangrove Ecosystem important?

Mangrove forests are among the most productive and biologically complex ecosystems on Earth, yet they are disappearing at an alarming rate. Globally, mangrove forests represent less than 1% of all tropical forests and less than 0.4% of the total forest estate. According to the Global Mangrove Alliance, an estimated 67% of mangroves have been lost or degraded, and an additional 1% is lost annually. Mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts.

These ecosystems provide extraordinary benefits that directly affect human well-being and environmental health. Mangroves protect coastlines from storm surges, tsunamis, and rising sea levels, while also shielding coral reefs, seagrass beds, and shipping lanes from siltation and erosion. They support rich biodiversity by providing nursery habitats, spawning grounds, and nutrients for fish, shellfish, migratory birds, insects, and countless endangered mammals, reptiles, and amphibians. Mangroves are also a vital tool in fighting climate change, as they take up to five times more carbon out of the atmosphere than forests on land.

• Mangroves act as natural coastal defenses, reducing the impact of natural disasters like tides and tsunamis.
• They provide essential nursery habitats for fish and crustaceans, supporting local fisheries and food security.
• Mangrove soils are highly effective carbon sinks, sequestering vast amounts of atmospheric carbon.
• These ecosystems protect coral reefs and seagrass beds from siltation and erosion.
• Mangroves contribute to the well-being, food security, and protection of coastal communities worldwide.

How to Observe International Day for the Conservation of the Mangrove Ecosystem

Individuals and communities can mark this day by learning about the critical role mangroves play in coastal protection and climate regulation. If you live near a coastal area, consider planting mangrove trees along the shoreline, choosing species that are adaptable to your local climate. You can also teach others about mangrove conservation by sharing educational materials, organizing community talks, or participating in local clean-up events that help protect these vital habitats.

Support organizations working to protect and restore mangrove ecosystems, such as the Global Mangrove Alliance, which aims to increase mangrove cover by 20% by 2030. Reduce your own carbon footprint by walking or biking instead of driving, and choose sustainable seafood to help reduce pressure on mangrove habitats. Every action, no matter how small, contributes to the preservation of these extraordinary ecosystems.

• Plant mangrove trees in suitable coastal areas.
• Educate your community about the importance of mangrove conservation.
• Donate to or volunteer with organizations focused on mangrove restoration.
• Reduce your carbon footprint by choosing sustainable transportation.
• Support sustainable seafood practices that protect mangrove habitats.
