The identification of natural carbon sinks is important for humans to fight global climate change. Tropical coastal wetlands have been considered crucial to tackle climate change for years, however, scientists have lacked evidence to show the advantages. Now researchers from the University of Göttingen along with other universities conducted a study in the mangrove-fringed Segara Anakan Lagoon in Java, Indonesia. Their study showed that the environmental dynamics in the mangrove ecosystems in Java, Indonesia, and carbon accumulation were regulated mainly by variations in the climate and human activity. Researchers emphasize that mangrove ecosystems need to be conserved and restored as part of the battle against increased global temperature.
