According to International Union for Conservation of Nature's (IUCN) Red List of Ecosystems. more than half of the world's mangrove ecosystems face collapse, with climate change posing a significant threat, according to the first global mangrove assessment.

• Over 50% of mangrove ecosystems at risk, with nearly 1 in 5 facing severe risk.
• Climate change threatens 33% of mangrove ecosystems, leading to increased risk from sea-level rise and severe storms.
• Deforestation, development, pollution, and dam construction also pose serious threats to mangroves.
• IUCN-led study involving 250+ experts in 44 countries classified mangrove ecosystems in 36 regions, assessing threats and risk.
• Climate change and sea-level rise could lead to the loss of 1.8 billion tonnes of carbon stored in mangroves by 2050, valued at least USD 13 billion.
• One-third of mangrove ecosystem provinces to be severely affected by sea-level rise, with 25% of global mangrove area predicted to be submerged in 50 years.
• Maintaining mangrove ecosystems crucial for mitigating climate change impacts, providing coastal protection, and supporting biodiversity.
