Ecosystem services are the benefits natural ecosystems provide to people. Ocean ecosystems face growing threats globally from overfishing, habitat damage, pollution, and especially acidification (Halpern et al., 2008). The most classic example is that of mangrove ecosystems, which help reduce the impact of tsunamis. �@�e��N����+��ס���U+��i���n���� ��^YG�E�{ڼ��{BW��еB֡�9o�x|�xd��Z&�VHo hӷM��=У�@�:�����Z�-����;hK��8��ۗ�.9����$�lIn7iq_�����(B��"[>��YQ6R�$���ؾ�s��*�p�D���o��ن�C��EؖK[��oo�沦m���EV���ށ��pM,TXH�0< ���9�@r��K��1��V�/��tT3���h0 �)���+ ��H���"�� 366 0 obj <> endobj The concept of ecosystem services has become an important model for linking the functioning of ecosystems to societal benefits. O[����8��ܝ�俒#@�!��hm��S6~9�~e�a�&�����o0���w}���) A mangrove commonly refers to two different things: a tidal swamp ecosystem found in tropical deltas, estuaries, lagoons or islands, and the characteristic tree species populating this ecosystem. This high level of productivity contributes to the wide array of species that inhabit mangroves or use them as refuges, migration sites, and nurseries. They protect the coastline from wave action and erosion, they're nurseries for all kinds of different types of organisms, and some of these are very important food types for us. The natural functioning of coastal ecosystems is needed to produce and sustain the vital flow of various goods and services to humans. This module provides guidance for people interested in mangrove ecosystem conservation, restoration and management.

So mangrove forests have one of Earth's most effective ecosystems for carbon sequestration and storage. Mangroves have been widely reviewed as supporting numerous ecosystem services including flood protection, nutrient and organic matter processing, sediment control, and fisheries. Explain one probable cause for the change in per capita waste from 2000 to 2012. Amazonian and Congolese rainforests, for example, provide heavy rainfall in key, agricultural areas. Mangroves absorb carbon dioxide and store carbon in their sediments, thereby lessening the impacts of global warming; and. Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. Ecosystems – living elements which interact with each other and their non-living environments – provide benefits, or services, to the world.. Ecosystem services make human life possible by, for example, providing nutritious food and clean water, regulating disease and climate, supporting the pollination of crops and soil formation, and providing recreational, cultural and spiritual benefits. Access to our library of mangrove resources, © 2020 Mangrove Action Project. Salt marshes and tidal creeks provide us with a wealth of benefits, referred to as ecosystem services, including maintaining healthy water, protecting us from flooding and erosion, providing nursery and essential habitat for commercial and recreational fisheries, and supporting recreational activities that have become part of the coastal lifestyle. endstream endobj 371 0 obj <>stream The stability mangroves provide is essential for preventing shoreline erosion. 5v�_����78�!��m4��/�U�n$3���Lk�d�bO�k��` ��w Mangrove forests are rich in biodiversity providing a habitat for wide varieties of animal and plant species. Commercial fisheries are provided by mangrove ecosystems. Marine ecosystems also provide other important services, associated with their regulatory and habitat functions, such as pollution control, storm protection, flood control, habitat for species, and shoreline stabilization. The aim of this paper is to conduct an ecosystem services valuation study for mangroves ecosystems, the results of which can be used to inform governance and management of mangroves. In general, the term ‘ecosystem services’ refers to the benefits people obtain from ecosystems. To this end, education and awareness strategies are also critical. Lot of works have been done on the valuation methods, data and classification systems for ecosystem services of terrestrial ecosystems compared to the mangrove ecosystems in the coastal and estuarine regions of the world. It presents a meta-analysis of the economic valuation literature and applies the estimated value function to assess the value of mangroves in Southeast Asia. soil stabilization & erosion protection; Ecosystem Services Of Mangrove Forests Other ecosystem services provided by mangroves include: Guatemala Rhizophora aerial rootsprotection from strong winds & waves; Mangroves’ protective buffer zone helps shield coastlines from storm damage and wave action, minimizing damage to property and losses of life from hurricanes and Some propagules may take root in the soil beneath the parent tree, but others may float for an extended period of time before anchoring to the shore. 392 0 obj <>/Filter/FlateDecode/ID[<5E359E53CDEA9E48A39578301DA6361D><232D2E760A4622449E52CDE902F5C5C4>]/Index[366 50]/Info 365 0 R/Length 116/Prev 560391/Root 367 0 R/Size 416/Type/XRef/W[1 2 1]>>stream These ecosystems services include: supporting, biological, provisioning, regulating, and cultural ... a beautiful intact mangrove. o,����j ���_��`���JC���?���]|(�w4֡~�'+^ ٢Z3��LוB�a[p�JC��%��s$�0�8��(��#�H3ðHG3pD����U�0p�L�l iFpha�@��ڀү��l�7������֡�����:�� ����ᝳWx7~7��G�^�T�ud��.Xɭ�\T�z+� In addition to their adaptation to salty conditions, mangroves have also evolved innovative reproductive strategies. Two of nature’s key pollinators are insects (particularly bees) and wind; without these two pollinators, growing agricultural crops would be immensely challenging for us as humans. The carbon value on the other hand is, um, is growing. Changes in local water conditions caused by upstream dams, irrigation and pollution have led to the loss of many mangroves. ea�a�����ҫ�i���3z]���3Bs:O!��=ߖ(�i�_B���IZ�!,��D�jt{�>���Ӌ|���i�A�_�^~��\~='����=�;O�G��ʃ�_�Y�L�@�Ҩ�O+���n�� �g2�����B�=�a�Y�rH��QV�����0� ��鴊 a�G�>x/i����Q%��N;!=�� Mangrove trees are removed by humans due to expanding agriculture. Many of the fish caught commercially in tropical regions reproduce and spend time in the mangroves as juveniles or adults. Mangrove systems are critically important habitats for a wide range of aquatic species, including fish, shrimp, molluscs and crabs, providing nursery, feeding and refuge areas and underpinning coastal food webs that support many commercial harvests, local subsistence harvests, and other sustainable uses such as limited timber and firewood harvests, local medicine production and other important local uses.

The provision of habitat for aquatic and terrestrial fauna and flora cannot be overlooked. Frequent correct responses included shoreline stability, maintaining or increasing biodiversity and flood control. Traditional and indigenous coastal populations have found sustenance from mangroves, collecting products and resources in a sustainable manner for hundreds or even thousands of years, including: Mangrove Action Project works with a variety of local and international entities to help preserve, restore, and educate on our global mangrove forests. By some estimates, less than 50 percent of the world's mangrove forests were intact at the end of the 20th century, and half of those that remain are in poor condition. ����tG{�,�w�`�~���v�t��5&�q������T*E�gٴ�g�f��l\8�Eޞc�R����>��.��ۺ�Ϻ��tJ1��>,|���(�,��(��������D?�66��F��J1�.�\4O���-%��#��c���; $!L w8���h�Qe�t"0��%e��6l�id�vG��0�4�Ly׸��ˠu��ƥ2z�_O2 Other ecosystem services provided by mangroves include: Sea grass beds and coral reefs depend on healthy mangroves to filter sediments and provide nursery grounds for resident species.

Mangroves are also home to snakes, lizards, and insects – which are actually the most abundant (both in numbers and species) above the tide. They survive high amounts of salinity either by excreting salt through their leaves, or simply by safely keeping it within their tissues. Hundreds of bird species have been identified in mangrove forests, and many species of tropical and sub-tropical marine species, such as fish and crustaceans, spend some part of their lives in mangrove wetlands as juveniles. endstream endobj 370 0 obj <>stream Mangrove trees have developed unique adaptations to the harsh conditions of coastal environments.
