The State of the World's Mangroves 2022

Healthy mangrove ecosystems are critical for global climate action – playing a key role in carbon storage and in building resilience to a rapidly warming world. Mangroves stabilize coastlines, reduce erosion, foster biodiversity growth and protect coastal communities by building their adaptive capacity and making them more resilient to the impacts of climate change, such as sea-level rise, storms and coastal erosion, Mangroves prevent more than US$65 billion in property damages and reduce flood risk to some 15 million people every year.

A Chinese company that dug a channel through mangroves and a coral reef to provide access to a multi-million-dollar resort and casino development on a Fijian island has been fined $FJ1 million ($650,000) by the High Court in Suva. The company was found guilty in April last year of

The State of the World's Mangroves 2021

Mangroves are vital components of the planet coastal ecosystems. Mangroves sequester carbon at up to four times the rate of terrestrial forests, making them tremendous allies in our struggle for net-zero carbon emissions by 2050. They stabilize coastlines, protected coastal communities against storm surges, reduce erosion and serve as a vast nurseries and habitats for fish, crustaceans shellfish and wildlife.

Mangroves are an overlooked hotspot of insect diversity despite low plant diversity

The world’s fast disappearing mangrove forests have low plant diversity and are often assumed to also have a species-poor insect fauna. We here compare the tropical arthropod fauna across a freshwater swamp and six different forest types (rain-, swamp, dry-coastal, urban, freshwater swamp, mangroves) based on 140,000 barcoded specimens belonging to ca. 8500 species. We find that the globally imperiled habitat “mangroves” is an overlooked hotspot for insect diversity.
