role of mangroves in climate change

The capacity of mangroves, sea grasses, and salt marshes to sequester carbon dioxide from the atmosphere is becoming increasingly recognized at an international level. “Every time a study looks at it, the rate is faster than we expected.”. Saintilan et al. Indonesia, Malaysia and Myanmar accounted for more than two-thirds of the released amount. As compared to terrestrial ecosystems, the research focus on coastal and marine systems is about a decade behind. Yet these ecosystems are exceptionally prone to extinction due to increased human interventions and changes in environmental boundary conditions. “The rate of sea-level rise keeps going up,” says Geselbracht, who was not affiliated with the study. An estimated 75 percent of game fish, and 90 percent of commercial species in South Florida depend on … 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. Role of Mangrove Forests in Climate Change Adaptation. In a particularly vicious twist, taking out mangroves not only eliminates their potential for storing carbon, it releases significant amounts — increasing the threats of climate change and sea-level rise and putting even more mangroves, and the communities and habitats around them, at risk. Mangroves and mapping help Mozambique tackle climate change "Mangroves are our first line of defence" By Adela Suliman | Fri, 27 Apr 2018 Seawalls and forests aim to … Here’s how: Science. s.parentNode.insertBefore(gcse, s); Mangroves are found in 123 countries, covering an area of 152,360 km, . Several studies have shown that mangroves play crucial roles in protecting coastal communities from the impact of large storms. Despite high rates of destruction and degradation, mangroves still play key roles in ameliorating coastal erosion, fostering coastal stability and assisting in human sustainability. But far less attention has been paid to a similar and equally important type of biome that is also increasingly at risk: Mangrove forests. The entangled roots of mangrove forests help to stabilize coastal areas through sediment capture and bio-filtration of nutrients and some pollutants from the water, and reducing coastal erosion. gcse.type = 'text/javascript'; “They should do the project in a more environmentally friendly way.”. Mangroves and climate change. The aim of this review was to present the impacts of a range of climate change factors on mangroves at a regional scale, and then to synthesize these trends at a global scale. 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. Every year thousands of tons of shrimps from aquaculture farms from Southeast Asia are exported to western markets. Mangroves also play a critical role in protecting communities from the harmful effects of climate change, like flooding from rising sea levels, which threaten both the balanced ecosystem and traditional ways of life in coastal villages. The capacity of mangroves, sea grasses, and salt marshes to sequester carbon dioxide from the atmosphere is becoming increasingly recognized at an international level. The effects of climate change are already being felt, especially in many coastal areas. 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. Blue carbon is the carbon stored in coastal and marine ecosystems. Perspective Global Significance of Mangrove Blue Carbon in Climate Change Mitigation Daniel M. Alongi Tropical Coastal & Mangrove Consultants, 52 Shearwater Drive, Pakenham, VIC 3810, Australia; Mangroves may help fight coral bleaching. Role of Mangrove Forests in Climate Change Adaptation. Mangroves play an important role in adapting to climate change and provide a plethora of ecosystem services that are fundamental to human survival. The best known area for mangroves in the whole world is the Sundarbans, a vast mangrove forest that spreads across the boundary between India and Bangladesh and covers an area of 6,500 km2, extending up to 85 km inland. One of the key challenges facing mangrove conservation is inadequate understanding of their multiple roles due to poor research, particularly in the areas of climate change mitigation and adaptation. Rutgers University climate data scientist Erica Ashe, one of the authors, says the current global rate is 0.134 inches, with some areas experiencing much higher rates. Mangroves and climate change Updated: Thu, 18 Oct 2018. 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.
