In return, the reefs protect the seagrass beds and mangroves from strong ocean waves. How do coral reefs benefit the economy? Mangroves are widely recognized for their functions of providing nursery grounds, shelter and food sources for reef fishes ( Laegdsgaard & Johnson, 2001 ; Mumby et al., 2004 ). Coral reef is one from many ocean ecosystem that we see frequently. Mangroves protect coral reefs from sedimentation, sequester massive amounts of carbon to combat climate change, adapt to rising sea levels, serve as nurseries in a vital food source for marine life while providing critical habitat for endangered species. Many coastal and indigenous communities rely on this wood for construction material as well as for fuel. (Read more about how mangroves support animal life.). (8) They are also very effective at diminishing storm waves. Tourists coming to dive need not only dive boats and guides, but also restaurants, hotels and commercial and entertainment facilities. Mark Butler MP 27 May 2016 Harvested for durable, water-resistant wood, mangroves have been used in building houses, boats, pilings, and furniture. How do coral reefs benefit the economy? The shade provided by mangroves protects the corals from high levels of solar radiation. Image: Purnadi Phan via Flickr, CC BY-NC 2.0 Cities, even those sited away from coastal areas, can benefit from nature-based solutions such as the restoration of mangroves and coral reefs to combat rising sea levels and global warming. The shady ecosystem offers a refuge from warmer temperatures and solar radiation, which can cause coral bleaching. WAVES Report Highlights Economic Benefits of Mangroves and Coral Reefs story highlights Engineering and insurance models should be used to reevaluate the benefits of habitats like mangrove forests and coral reefs, rather than building walls against floods and rising seas, according to a technical report published by Wealth Accounting and the Valuation of Ecosystem Services (WAVES). While coral reefs can grow to become as massive as an island, when waters become too warm, too cold, or overly acidic, entire coral ecosystems can be lost. Highly vulnerable, coastal regions that would benefit the most from the conservation of mangroves and coral reefs span across Central America, the … Coral reefs are considered to be one of the most diverse and valuable ecosystems on earth. No matter where you live, near the coast or hundreds of miles away, there are several things that you can do to keep coral reefs healthy. surges, currents, waves and tides. Mangroves are widely recognized for their functions of providing nursery grounds, shelter and food sources for reef fishes ( Laegdsgaard & Johnson, 2001 ; Mumby et al., 2004 ). • Of these benefits, carbon sequestration by mangroves (~$6.7 billion) and tourism by coral reefs (~$5.7 billion) are the most valuable. Mangroves act to purify the water from human wastes and pollutants, and in doing so, coral reefs are less effected. Like coral reefs, mangrove forests are extremely productive ecosystems that provide numerous good and services both to the marine environment and people. Mangroves are able to reduce non-storm waves by 70% of their near shore height! • Mangroves and seagrass beds together provide around $6.7 billion in ecosystem service benefits. This makes mangrove forests vitally important to coral reef and commercial fisheries as well. Both stony coral -- … The remaining 20% mangroves are scattered on the west coast from Kutch to Kerala. Thousands of species can be found living on one reef. In many cases, tourism asociated with reefs has expanded to transform the entire economy of a region. Previous studies suggest that corals that are accustomed to environmental fluctuation can better weather extreme heat. The impact of Typhoon Haiyan on the mangroves and coral reefs in the Concepcion municipality was devastating. Healthy coral reefs support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation. Proximity to mangroves was another important positive factor associated with fish communities, as the biomass and species richness of fishes were greater on coral reefs near mangroves. I don’t think so. Below, we have highlighted the benefits of mangroves, and recommend immediate action to protect and […] In this case, the coral reef offshore provides a break, slowing incoming waves. The. Reefs worldwide are facing destruction at every turn, as can be seen in this map of the Mesoamerican Reef, at the other end of the Caribbean from St. John. 2 Encourage the role of the community in protecting mangroves 4,5,6,16 3 Stop using coral reefs as building and decorative materials 7,8,9,10,13 4 Support community participation in coral reef conservation 14, 15,17,18 Table 3 The Category of Knowledge and Attitude Category Interval Score Very High X>81.28 High 70.64>X<81.28 Coral reefs and mangroves save billions of dollars in flood damage. Reefs are huge deposits of calcium carbonate made up mainly of corals. When the sea grass dies it helps to create future plant growth. Herbivorous fish feed mainly on plant material. Not only as a shelter and food resources for many living beings but the importance of coral reefs … Mangroves In Reef Aquaria - Growing mangroves enables one to decorate a tank to look like a fringing reef that surrounds an island, as seen from the ocean. Mangroves and coral reefs can help protect millions from rising seas . Mangroves produce coloured dissolved organic matter (CDOM) that can be transported over near shore reefs affording them some sunscreen protection. They do, however, play an important role in driving consensus around how to measure and monitor ecosystems like coral reefs and the benefits they provide to people. Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield. Value of Coral Reefs & Mangroves in the Caribbean -- Economic Valuation Methodology V3.0-- World Resources Institute January 2009 This document contains a methodology for assessing economic value of three goods and services provided by coral reef ecosystems in the Caribbean. According to a recent report, these goods and services are conservatively estimated to be worth US$186 million each year.They include: Fisheries: Mangrove forests are home to a large variety of fish, crab, shrimp, and mollusk species. Mangroves, seagrass beds, and coral reefs are often found together and work in concert. What do coral reefs have to do with our economy? Researchers say corals have been bleached and reefs have lost their structural complexity as a major consequence of warming seas The coastline is protected because the roots of mangroves act to trap sediments that would otherwise be washed back out by the waves. Growing among the tree roots were more than 30 coral species, including four threatened species. Timber and plant products: Mangrove wood is resistant to rot and insects, making it extremely valuable. Luxuriant patches of mangroves are found on all the other continents but the best mangroves are found in Asia, especially in India and Bangladesh - the Sunderbans are the largest mangrove forest in the world both in size as well as biodiversity. Vulnerability of Fiji’s mangroves and associated coral reefs to climate change 9 mates is Watling (1985), who found 385.43 km2 remain- ing of an original mangrove area of 410 km2, with 24.57 km2 (7%) developed to other uses. These human activities paired with the threat of climate change, warming sea temperatures, and increased ocean acidification are causing corals to die-off at an alarming rate. These fish rely on those coral reefs to get their nutrition and the coral reefs can also get the benefits from those fish in return. Over half a billion people depend on reefs for food, income, and protection. From the Great Barrier Reef to the Caribbean’s treasures, they are an integral part of ocean life.. The richest mangrove communities occur in tropical and sub-tropical areas, i.e., between the 30°N and 30°S latitudes where the water temperature is greater than 24ºC in the warmest month, where the annual rainfall exceeds 1250mm and mountain ranges greater than 700m high are found close to the coast. Coral reefs often form the backbone of local economies. Importantly, mangroves have the ability to reduce impacts of water quality. 2020 National Geographic Partners, LLC. » Mangroves protect water quality by removing nutrients and pollutants from stormwater runoff before they reach seagrass habitats and coral reefs. Aside from nurturing future generations of coral reef fish, mangroves and seagrass meadows trap material that runs off the land, providing clearer coastal waters over reefs.
