Mangrove ecosystems are highly productive and rich in biodiversity and offer a variety of goods and services, both economic and ecological. The importance of mangroves and the threats to their persistence have long been recognized, leading to actions taken locally, by national governments, and through international agreements for their protection. The Importance of Mangroves: A Call to Action launched today at the 16th Global Meeting of the Regional Seas Conventions and Action Plans, describes how emissions resulting from mangrove losses make up nearly one-fifth of global emissions from deforestation, resulting in economic damages of some US$6 - 42 billion annually. https://doi.org/10.1016/j.aquabot.2008.02.009. Coastal residents who use mangroves and their resources may have considerable botanical and ecological knowledgeable about these forests. There is growing research interest in the ethnobiology, socio-economics and management of mangrove forests. Mangroves need to be understood for the valuable socio-economic and ecological resource they are, and conserved and managed sustainably. A major ecosystem service provided by these mangrove forests is the habitat they build for many commercially important species including fish and crabs, who live in the complex root network of mangrove forests. %PDF-1.3 %���� ����I>g,al�7��`� �6�l�@Z�a�d�����~��c���d��"/w���n= �c`7_��ā잓 |�f� �� , revenues generated from fishery, timber, fuel wood, fodder, honey, wax, and … The largest mangrove forest in the world is Sundarban Mangrove Forest.

As noted above, mangroves provide a wide range of vital ecosystem services, which have an equally wide range of value. For example over-harvesting of wood for timber production – mangrove is a cheap, strong and durable building material. Economists generally decompose the total economic value of ecosystems into direct use, indirect use and non-use values. 35 no. What are mangroves? In this review, we explore the status of mangrove forests as well as efforts to protect them. Mangroves protect coastal areas from erosion, storm surge, and tsunamis. Although there are exceptions, mangrove forest products are typically harvested in a small-scale and selective manner, with harvesting efforts and impacts concentrated in stands that are closer to settlements and easiest to access (by land or by sea). 123 0 obj <> endobj Direct use values refer to consumptive and non-consumptive uses that encompass physical interaction with the mangroves and their services e.g. As a soft engineering technique, … In plants, the first line of defense against abiotic stress is in their roots. Recent advances in remotely sensed, geo-spatial monitoring provide opportunities for researchers and planners to better understand and improve the management of these unique forested wetlands.

Economist generally divide the total economic value of mangrove into three major groups namely (i) Direct use value (ii) Indirect use value and (iii) Non-use value. Mangroves protect shorelines from erosion. Numerous studies have been done on the economic values of mangrove ecosystem services. They maintain water quality and clarity, filtering pollutants and trapping sediments originating from land. Coastal Protection- Mangroves stabilize coastlines and preserve coral reefs, as well as filter water. h޼��n۸��༃�lQdG���8�&i�q��m�Ŧm5��Jr����oHɖm5�.p Т���6�qH�u\G���wϑ���td���DJ�wҍ���.

Some of these outputs, such as timber, are freely exchanged in formal markets. 215-218. Likewise, the ecological and economic literature of mangrove ecosystems in Karachi Coastal areas has brought significant ecological and economic values which contribute to the local economy. Anne Birch Marine Conservation Manager, TNC Florida Mangroves are important to the ecosystem too. For the longest time, mangrove resources have been used primarily for wood harvesting, barely taking into account the important role they play in biodiversity and shoreline protection. The threats to mangroves in Kenya are many, and most of them human-induced.

Mangroves are the rainforests by the Sea. Mangroves support diverse, local fisheries, and also provide critical nursery habitat and marine productivity which support wider commercial fisheries. Commercially important fish rely on mangrove root systems for habitat.  Mangroves are those plants that thrive along coastlines, lagoons, and estuaries in the tropics and sub-tropical regions. Mangroves therefore build their own environment. More attention is now given to managing remaining forests sustainably and to restoring those degraded from past use. Mangroves are wonderful ecosystems and now with the threat of climate change, their importance is being restored. Mangroves provide numerous important ecosystem services. Watch Queue Queue. One important observation from this analysis, however, is that the benefit of protection is only accrued from wide mangrove belts. Mangrove C assimilation may be under-estimated because of flawed methodology and scanty data on key compo-nents of C dynamics. Their role as efficient coastal defense systems is perhaps most visually evident, often saving properties and lives from the destructive force of tropical storms. By engaging international organizations such as Seacology and multilateral platforms like BOBLME, Sri Lanka generates awareness about how important mangroves are to coastlines and encourages countries to share best practices for their conservation. Results The role of mangroves as C sinks needs to be evaluated for a wide range of biogeographic regions and forest conditions. The Sundarbans mangrove forest of Bangladesh provides ecosystem services having great importance for local livelihoods, national economy and global environment. Our results are important for policy makers because they highlight that mangrove conservation and restoration efforts can be used in coastal lowlands to protect economic activity against tropical cyclones.

Economic importance of mangrove-associated fisheries Fisheries production constitutes the major value of marketed natural resources from mangrove ecosystems. Mangroves also help prevent erosion by stabilizing sediments with their tangled root systems. Economic Importance of Mangroves, Afforestation and Reclamation Sathiadhas, R and George, J P and Jayasurya, P K and Mathew, Ansy (2005) Economic Importance of Mangroves, Afforestation and Reclamation. Mangroves retard the tidal movement of water, allowing sediment to be deposited as the tide comes in, and leaving all except fine particles when the tide ebbs. They are also important nursery areas for many fresh water and reef […] Mangroves and the shellfish that live on roots also filter water, and hold pollutants from getting out to sea. Mangals are highly biodiverse habitats that host a large variety of unique organisms from barnacles and oysters to fiddler crabs, mudskippers or even near-endemics like Costa Rica’s Mangrove Hummingbird or PNG’s Sheathtail Bat and various birds. Moreover, mangroves also play an important role in stabilizing shorelines in coastal streams and estuaries by protecting them against tidal bores and soil erosion.   These salt-tolerant plants make significant socio-economic and environmental contributions as they protect the coastal and inland areas from severe … The City of Manila is named after maynilad – which literally means “there is nilad”, a mangove scientifically known as the Scyphiphora hydrophyllacea, which lined the shores of Manila Bay and the banks of the Pasig River (Gruezo, 1999). These forests also provide valuable ecosystem services that benefit coastal communities, including coastal land stabilization and storm protection. Fish- Mangroves preserve biodiversity and allow fish and shellfish to thrive.  Mangroves significantly facilitates in moving organic matter and energy from the land to marine ecosystems.
