Mangrove ecosystems serve as breeding, feeding, and nursery grounds for many shellfish, fish, and other wildlife. Blue carbon is the carbon stored in coastal and marine ecosystems. That’s the good news. Subscribe to The Revelator’s weekly newsletter. On a regional scale, Southeast Asia has one-third (51,049 km2) of the world’s mangroves – more than any other region in the world. Floating on clear, calm water, my travel group and I kicked over tall seagrass beds and rays camouflaged in the sandy flats. Moreover, intact and healthy mangroves act as a natural buffer, contributing to the reduction of impact forces and depth and velocity of natural hazards, thus contributing to coastal communities’ ability to adapt as the frequency and severity of such events increases as a result of climate change. A paper published in Science in June looked at data on thousands of years of sea-level rise and mangrove accretion. In addition, Bangladesh already has seen significant loss of mangrove forests to shrimp farming. A 2018 study calculated that the world’s mangrove forests suck up more than 6 billion tons of carbon a year. Mangrove forests could play a crucial role in protecting coastal areas from sea level rise caused by climate change, according to new research involving the University of Southampton. Mangrove plants are mostly trees and large shrubs, but also include ferns and a palm species. 01 : 30 MIN SEC. Climate Change How Singapore's mangroves can contribute in the battle against climate change.

Mangroves and climate change. Saintilan et al. Between 2000 and 2015 mangrove destruction released up to 122 million tons of carbon — more than two and a half times the amount emitted by California wildfires between 2001 and 2010. Pierre Taillardat. Climate change refers to a change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer (IPCC 2014).Managing the risks of climate change involves mitigation and adaptation decisions with implications for future generations, economies, and environments. But far less attention has been paid to a similar and equally important type of biome that is also increasingly at risk: Mangrove forests. However, despite such diversity in the roles of mangroves, these ecosystems are still often seen as valueless wastelands available for other uses. “The second to largest seaport [in Bangladesh] is close to Sundarbans. In order to raise awareness of the multiple benefits of mangrove ecosystems, there is a need to conduct more research and also focus more on expanding mangrove areas in participation with local communities and other key stakeholders. This ability of mangroves and other coastal vegetation to store such large amounts of carbon is, in part, due to the deep, organic rich soils in which they thrive. ... about one per cent - they have a role to play when it comes to carbon storage. The effects of climate change are already being felt, especially in many coastal areas. The aerial roots of mangroves hold back sediments and reduce pollutants from sewage and aquaculture in estuaries and coastal waters. Yet, these people are often unaware of the key role mangroves may play, especially if the associated fisheries are offshore. Front. Like other plants, mangroves take carbon dioxide from the air as they photosynthesize. In many countries, mangrove wood is used to produce charcoal, and as firewood. An initiative of the Center for Biological Diversity. Mangroves and marshes key in the climate change battle 02/02/2017 03:47 am ET Updated Feb 02, 2018 With the advent of green technologies, it is easy to view the battle against climate change … Here's what that means for us. Mangroves have declined by nearly half in the last 50 years. The bad news: Mangroves face numerous threats — 35% were lost between 1980 and 2000, and since the turn of the 21st century almost 1 in 50 of the remaining mangrove forests has been cut down.
