Mangroves cover 13,989 square kilometers along Brazil's coast - an area larger than the U.S. state of Maryland - and are a vital protection against climate change, according to biologist Renato de Almeida with the nearby Federal University of Reconcavo da Bahia. Climate change components that affect mangroves include changes in sea-level, high water events, storminess, precipitation, temperature, atmospheric CO 2 concentration, ocean circulation patterns, health of functionally linked neighboring ecosystems, as well as human responses to climate change. Threats from Climate Change Rising sea levels and changing salinity pose the most serious threats to these ecosystems. Now, in a harbinger of climate change, mangroves are expanding from tropical zones into temperate areas. Sea levels are rising and the chemistry of the oceans is shifting (IPCC 2007 and NRC 2011). Most of the mangrove forestation is in the Indian Ocean, whether it be on the coasts of India or surrounding the islands of Indonesia (see Locations of Forests).The climate in this area of the world varies from day to day, with the yearly average being 22 °C (72 °F). And the climate keeps on changing, bringing ever more erratic rains, storms, and temperature swings. Tim Christophersen, a forest and climate change expert with UNEP, told the Thomson Reuters Foundation that protecting and conserving mangroves is crucial for the climate resilience of the world’s coastlines as they face threats such as rising sea level, increasingly frequent and powerful storms and saltwater intrusion into drinking water. Mangrove forest canopy near Jones Lagoon. Mangroves are prevalent in tropical south Florida, but the plants have been moving farther north as climate change makes freezing weather less common. But if mangroves … We review the state of knowledge of mangrove vulnerability and responses to predicted climate change and consider adaptation options. Mangrove ecosystems provide goods and services highly valued by the people of the Pacific. Mangroves provide numerous ecosystem services that contribute to human wellbeing (Vegh et al., 2014; Van Bochove et al., 2014; Friess, 2016) and may be threatened by climate change. Khan's top adviser on climate change, Malik Amin Aslam, did not respond to multiple requests for comment. Mangroves and Climate Change 1. Around the globe mangroves enhance coastal fisheries, sequester carbon, provide provisions to local inhabitants, filter Ecological Services• Sediment trapping*• Land-sea buffer*• Breeding, feeding, nurseryarea for fish, oyster, crab,shrimp**• Bird nesting (herons,pelicans, spoonbills, etc. This makes mangrove forests – and their restoration – one of the planet’s best and most important defenses against climate change. Climate Change May Wipe Out Large Mangrove Forests, New Research Suggests Mangroves help protect coastal areas from flooding and sequester more … Mangrove Forests(Global Explorers Blog) 2. Most mangrove sediment surface elevations are not keeping pace … Coastal wetlands have disproportionately high carbon densities, known as blue carbon, compared to most terrestrial ecosystems. Friendship’s mangrove plantation project is part of a holistic program that includes health interventions, water treatment plants, special assistance for fishermen, sustainable economic development programs, disaster risk reduction, climate change adaptation, which have been set up gradually over the years. One feature of mangroves that we’ve long benefited from is the protection they offer to our coastlines. With climate change, coral bleaching episodes are becoming more frequent around the world. Ranges of mangroves have naturally waxed and waned over the years, influenced by the weather, but with climate change has come a crucial reduction in crop- and tree-killing freeze events. This entry was posted in Coastal Erosion, In the news, Kiribati, Media room and tagged climate change, coastal erosion, Environment and Conservation Division, mangroves, Ministry of Envrionment, press release on July 25, 2013 by webadmin. Weather in Mangrove Forests can ranges drastically because of their location in mainly tropical climates around the world. Mangroves can protect coastal areas from erosion and floods, and Abu Dhabi is regenerating them to help fight climate change. Seagrass beds, coral and mangrove islands are home to diverse species including reef sharks, Goliath groupers, rainbow parrotfish, long-spine sea urchins and hawksbill sea turtles. Mangroves and their blue carbon stocks are at risk globally from land‐use and land‐cover change (LULCC) activities such as aquaculture, alongside biophysical disturbances such as sea‐level rise and cyclones. A single acre of mangroves can drop two to three tons of leaves per year! Blue carbon ecosystems (mangroves, sea grasses and salt marshes) can be up to 10 times more efficient than terrestrial ecosystems at absorbing and storing carbon long term, making them a critical solution in the fight against climate change. Adapting to climate change. Waves lose their power passing through dense mangrove … However, this unique ecosystem faces continuing threats from over harvesting, degradation and land reclamation. Based on available evidence, of all the climate change outcomes, relative sea-level rise may be the greatest threat to mangroves. Globally, the UN Environment Programme estimates two thirds of mangroves have been lost or damaged, with the rest declining by 1% a year. Human impacts on mangroves, including climate change, have received much attention of late especially because mangrove deforestation is occurring at a rapid rate. As the country in the world with the largest cover of mangrove forest, Indonesia has global significance in climate change mitigation. Distribution(“Environment—Tropical Shelf Seas and Shores”) 3. Drowned? Where mangroves are sheltered by coral reefs killed by climate change, damage to mangroves from increased wave action is expected to rise. Mangrove ecosystems grow in the intertidal zones in tropical and sub-tropical regions and are likely to be early indicators of the effects of climate change. Mangroves have (carbon) hoarding issues. The conservation of mangroves and associated ecosystems is a key natural adaptation strategy and mitigation measure to climate change. Restoring mangrove forests is one way scientists in places like Florida have sought to defend coastal communities from the ravages of climate change. The destruction of coral reefs will further harm mangroves, and vice versa, leading to reduced coastal protection and … Like other plants, mangroves take carbon dioxide from the air as they photosynthesize. Hari Sreenivasan reports on … The best estimates of predicted climate change in the literature are presented. Mangroves and climate change Updated: Thu, 18 Oct 2018. A Brazilian court blocked government's move to revoke key regulations protecting the country's tropical mangroves after the move was fiercely criticized by environmental and climate groups. Despite high rates of destruction and degradation, mangroves still play key roles in ameliorating coastal erosion, fostering coastal stability and assisting in human sustainability. Introduction. Mangroves are prevalent in tropical south Florida, but the plants have been moving further north as climate change makes freezing weather less common. Mangroves and Climate Change. Mangroves do more proportionally than any other forest to sequester carbon – up to 5x more per hectare than tropical rainforests. 1. Mumbai's Disappearing Mangroves: A Weapon Against Climate Change Is Under Threat : Goats and Soda Studies show that the city lost nearly 40 percent of its mangroves … With the advent of green technologies, it is easy to view the battle against climate change as one for the tech world. 2008). Climate change impacts, such as storms and rapid sea level rise, are additional factors that lead to reduction in mangrove forests. There is still hope, however: If we protect them, mangroves will continue to offer many benefits for humans, especially in disaster risk reduction and climate adaptation. Climate change will also lead to the destruction of coral reefs, which protect mangroves from wave action and have a symbiotic relationship with mangrove forests. Mangroves are among the most carbon-rich forests in the tropics, according to a 2011 study in Nature Geoscience, making them particularly important for mitigating climate change. In terms of climate change mitigation, mangroves serve as carbon sinks and the loss of mangrove forests can result in significant release of stored carbon. Mangrove forests are incredibly productive ecosystems. Bundle Island, located in the Arabian Sea, is … A lesser-known but increasingly recognised solution lies in nature. Boulder brain corals, for example, were found in abundance under the mangroves … The annual economic value of mangrove habitats is estimated at $80,000 to $360,000 per acre. Mangrove ecosystems are threatened by climate change. The rates at which these impacts are occurring is likely to exceed the ability of mangrove forests and the species that live within them to adapt (Gilman et al .
