Morrison (1990) defines restoration as follows: ”restoration is the re-introduction and re-establishment of community-like groupings of native species to sites which can reasonably be expected to sustain them, with the resultant vegetation demonstrating aesthetic and dynamic characteristics of the natural communities on which they are based”. The level of survival of the restoration project sites ranged from 0 to 78% and only three sites, that is, The results of each R/R project, whether successful or not, should be published, as they are critical sources of data and information for further development of mangrove R/R practices and methods within the community of restoration ecology science. The recovery and protection of mangroves can be increased by these plans, in which not only the ecological issues are taken into account, but also the economic and social issues (, The human factor in mangrove restoration should not be underestimated (. These benefits can be in the direct use of harvesting the mangrove ecosystem natural resources: External support (for neighbouring ecosystems), Scientific research and education (botanical interest). The success of restoration through replanting seems to depend largely on availability of suitable sites and species and the involvement of the local community (Walters et al., 2008). Transportation distance between seedling source and planting site, Seedling mortality rate between collection and planting, Cost of raising specific species in nurseries before transplantation because they cannot be directly planted on mud flats due to strong wind and wave forces, Scale of post-implementation monitoring operations, Clearly, estimating the costs of mangrove restoration is complex and depends on a large number of factors. When the tsunami struck at the 26 of December 2002, much of the land around the village was flooded, but this village suffered only minimal damage. This also influences the specific mangrove species that will grow at this location (McKee, 2002). In the Building with Nature research program guidelines are created for governing eco-engineering projects. Meer informatie hierover vindt u op onze, Mangrove forests are estuarine wetlands, the area where the river meets the sea. Unlike many planting projects, CBEMR works with nature and takes into account mangrove ecology and biology to restore degraded mangroves by mimicking natural processes. For more than 30 years, a community in the central Philippines has been actively involved in reforesting and protecting a mangrove site, which has expanded from 50 hectares to 220 hectares (124 acres to 544 acres). The elaborate giraffe gymnastics occurred in July 2017 when Dr. Freid joined us to conduct the initial botanical assessments of the two terrestrial sites. This project involved the expansion of an existing mangrove forest on the seaward side of a dike system estimated planting capital and recurrent costs at approximately US$41 per hectare of mangrove planted, at 2009 price levels. This is contrary to more conventional approaches where after implementation projects are finished. Saint Lucia’s Ma Kôté mangrove forest is the largest in the Eastern Caribbean, but it recently has sustained severe damaged due to poor water circulation. Situated between land and sea, the mangrove forest contains many different species which, depending on their location, are more or less salt tolerant. This natural regeneration avoids the costs of building and running an expensive nursery and planting out seedlings. There is a need to combine the technological, economic and social knowledge on mangrove restoration, to make mangrove restoration more successful (CANVAS workshop). Ignoring the changes of topography and undulations of the site because of rigid line planting risks planting in channels or depressions, which are or will become the vital hydrological channels of a natural mangrove. In summary, five critical steps are necessary to achieve successful mangrove restoration: 1. This will preserve habitats and ecosystems into the future. Coastal Resource Group is a 501 c 3 non-profit organization that works with public and private partners to conserve Florida’s native coastal wetlands. Mangrove forests are situated in the intertidal area between land and sea. Scientific data shows that when this method is used, the ecological functions of the mangrove forest are quickly restored. Deltafacts: altijd de nieuwste feiten over klimaat, waterbeheer en waterkwaliteit. Time series photographs of a hydrologic mangrove restoration project at West Lake Park, Hollywood, FL, USA (A) Time Zero, July 1989, (B) Time Zero + 28 months, November 1991 and … Mangrove restoration is an activity that fits well in the working with nature concept because mangrove forests serve as natural coastal defence. MAP promotes and teaches its best practice ‘Community-Based Ecological Mangrove Restoration’ (CBEMR) technique. The work and social agreements need monitoring beyond 3-5 years to ensure the interventions worked and social agreements are being adhered to. Since then, we have worked on mangrove monitoring; the design of living shorelines; and the design of seagrass, dune and mangrove restoration, including the planting of native vegetation throughout the region. On-going researchAs stated before, much is learned by doing. The protective function of mangrove forest can be split up in wave attenuation, windbreak and stabilization of the shoreline by retaining sediment (, The tidal movement of water is not disturbed by breakwaters; it is actually the roots of the mangroves that reduce the velocity of the water and capture sediment. Mangroves are capable of protecting the coastline against erosion caused by wind, waves, and currents, and they can reduce the impact of storms and hurricanes. Other objectives could be landscape enhancement, sustainable productions of natural resources and protection of coastal areas (Morrisson, 1990). A study by these authors calculated the costs and benefits of a mangrove restoration project in Vietnam. These are human-induced degradation and natural disturbance related. Such a plan can only be implemented successfully when the local community is aware of the benefits offered by mangrove forests; the lack of public awareness of the usefulness of mangrove forests for flood and erosion protection may hinder the realization of these plans. Planting alone; this restoration usually fails because of lack of attention for the physiological tolerances of mangroves to tidal inundation. An international database of mangrove restoration projects would reduce the likelihood that unsuccessful restoration projects would be repeated elsewhere. Work together with communities, organizations and local government in order to: The success of restoration through replanting largely depends on the availability of suitable sites and species (Walters et al., 2008). Mangroves are very productive eco-systems; they provide benefits in different ways for many parties. Understanding which species are suitable for an individual site takes experience, and knowledge of mangrove ecology, biology and the various gradients on a site such as inundation, salinity and wave energy. Especially in delta and coastal areas where a large natural belt of mangrove exists, a significant protection against storms is possible. The costs of individual projects should be calculated on a case-by-case basis (Tri et al., 1998). (Tri et al., 1998). Excavation or fill; this is a very expensive category, due to the high cost related to earthmoving on a large scale. There is a big step to be made to upscale small restoration activities. Many effective mangrove restoration projects, like the mentioned one in South India, have been conducted through an approach of ‘learning by doing’. Background. The principal objectives of this project are carbon emission reduction, climate adaptation, and biodiversity conservation. Through this local sedimentation capitation, coastal erosion is diminished and with that stabilization of the shorelines takes place (Marchand, 2008). Mangrove restoration is based on a strategy of ‘working with nature’. This will also reduce or even avoid the cost of restoration and planting schemes. Click the link adjacent to get in touch with our team: The Mangrove Action Project (MAP) has adopted ‘Ecological Mangrove Restoration’ (EMR) as developed by Robin Lewis of Florida. There is a massive mangrove die-back due to changes in the hydrological system, which is sometimes caused by natural events, but is more often the result of human interference with the natural hydrology (Erftemijer and Teunissen, 2009). Understand the normal local hydrology that controls the distribution, settlement and growth of mangrove species. The MAP team engages in extensive discussions before the training to ensure the workshop is tailored to the needs of participants involved and the local mangrove conditions. Therefore working with nature solutions require adaptive pathways for decision-making and an adaptive governance approach to facilitate implementation and maintenance of the working-with-nature solutions. Hydrologic restoration (with and without planting). Lewis and Marshall (1997) have suggested five critical steps are necessary to achieve successful mangrove restoration: 1. There is a big step to be made to upscale small restoration activities. The recovery and protection of mangroves can be increased by these plans, in which not only the ecological issues are taken into account, but also the economic and social issues (Biswas et al, 2009). A lot of expertise on mangrove restoration has been gained during the past decades. Nine out of 23 project sites (i.e. These might include local or international NGOs, Environment or Forest Department staff, local government units and other relevant and interested groups. Good hydrology is vital for a healthy functioning mangrove and the provision of the full suite of ecosystem services. Implementation can therefore take many forms, from digging to improve site hydrology, to agreements to divert more fresh water into a site, or community mangrove management rules about harvesting of mangroves. Mr. Lewis and vice president Curtis Kruer were associated with the world’s largest and most successful seagrass and mangrove forest restoration project. Mangrove restoration projects for improving coastal resilience are underway in many places , particularly in countries like the Philippines , Bangladesh, Vietnam, Indonesia and Thailand, which are heavily affected by flooding … MAP also facilitates a CBEMR e-group with over 280 members worldwide sharing information and experience on more effective ways to rehabilitate mangroves. Biswas et al., (2009) for example state that poor socio-economic conditions and intensive human intervention are enormous challenges for mangrove restoration in Southeast Asia. Since environmental impactsare an ongoing threat, to successfully restore an ecosystem implies not merely to recreate its former condition, but to strengthen … The India Sundarbans Mangrove Restoration project seeks to plant 6000 ha of mangroves over three years that will store a projected 700,000 t of carbon over 20 years in their biomass and soil. A constraint to successful implementation of mangrove restoration is an incomplete understanding of the ability of a clear-cut, degraded wetland to recover, and of the success rates of mangrove restoration. Through all of its work, MAP also raises awareness among those participating as to the importance of mangrove forests, whether participants are policy makers, local citizens, or NGOs. The advantage of this approach is that it is supported by the local population. Mangrove Action Project has implemented both CBEMR projects and trainings in various countries around the world, demonstrating an effective and sustainable approach to mangrove forest restoration. For example, in Bangladesh 120,000 ha of mangroves have been planted since 1968 (, Many mangrove forests were lost during the last decades of the 20th century. On-going research and monitoring of current mangrove restoration projects can provide insight into the preconditions for successful mangrove restoration. An adaptive governance approach includes principles of continuous and collective learning to include new insights and knowledge, a participatory monitoring program, wide participation of stakeholders, and a continues process of reflexive decision-making. Roy R. “Robin” Lewis III, has over 40 years of experience in seagrass meadow and mangrove forest mapping, management and restoration in the USA and twenty-two foreign countries. Mangrove R/R projects implemented in the Asia and Australasia sectors of the IWP (a, b). Kondikara et al. Discussion and agreement within a village about project objectives, who does the work and equitable benefit sharing, are greatly aided by mapping of the site and frequent public engagement to discuss proposed activities. Only in more developed countries this type of mangrove restoration activities could possibly be performed (. Wetlands International, IUCN Netherlands and Oxfam Novib state that sustainable aquaculture production can help in restoring and conservation mangrove ecosystems. These benefits can be in the direct use of harvesting the mangrove ecosystem natural resources: Indirect use is more difficult to express in a monetary value, these are: The last benefit category is non-use or preservation value. Mangroves are forests in intertidal areas, with medium height trees and shrubs. Until researchers, NGOs, and government agencies can work together, mangrove restoration has an uncertain future in Sri Lanka. Through this local sedimentation capitation, coastal erosion is diminished and with that stabilization of the shorelines takes place, Large scale restoration activities are happening less. MAP has actively rehabilitated mangroves in Thailand and Indonesia, as part of post-tsunami recovery, while being involved in consulting on shoreline and mangrove restoration projects elsewhere. Hence, where necessary, hydrology should be improved by digging and then let nature do the rest. This was disclosed Tuesday by Guyana Mangrove Restoration Project (GMRP) Coordinator, Mr. Bissasar Chintamanie who said the Region Five site is one of several identified for such development in future. These relate to the involvement of local communities, the use of pilots, and adaptive management structure and learning-by-doing approaches. In the past decades a lot of experience has been gained with mangrove restoration in tropical areas. Mikoko Pamjoa (“Mangroves Together”) is a community-led restoration project along Gazi Bay, on Kenya’s south coast. In the Building with Nature research program guidelines are created for governing eco-engineering projects. Lewis, R. (2001), studied mangrove restoration activities and divided these into three categories: For successful mangrove restoration the following six steps are identified. They are located mostly along tropical coastlines and some subtropical coastlines (see figure 1). MAP has completed EMR training workshops in Cambodia, El Salvador, French Guiana, Honduras, India, Indonesia, Malaysia Myanmar, Senegal, Sri Lanka, Tanzania, and Thailand, and plans to additional workshops where there is interest. All rights reserved, Nursery and planting-focused restoration projects have a tendency to utilise only the propagules of species that are easy to handle, such as those from. In the past decades a lot of experience has been gained with mangrove restoration in tropical areas. Situated between land and sea, the mangrove forest contains many different species which, depending on their location, are more or less salt tolerant. climate change or land-use) and possible actions. These theoretical business models should be tested and further expanded. “There was a major restoration project in Saint Lucia, and their shade house is 12 by 14,” she said. In order to yield successful results, coastal wetland restoration strategies need to be adapted to the rapidly-changing coastal landscape. There are a lot of benefits related to mangrove restoration (as stated before), which could, in theory, be commercially exploited. Different parties can use the mangrove ecosystem as a resource for producing products and services. Next to the physical conditions, the governance setting around the restoration activities is very important. Commercial exploitation of the different function of mangroves can play a role in the restoration activities. Mangrove forests are situated in the intertidal area between land and sea. “We don’t know the exact percentage, but most of the mangrove restoration projects around the world that are attempted are not successful,” Lewis says. [G M E Perillo;] -- Coastal Wetlands, Second Edition: An Integrated and Ecosystem Approach provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide. Local training to increase community understanding and awareness of mangrove values is needed. Mangroves are capable of protecting the coastline against erosion caused by wind, waves, and currents, and they can reduce the impact of storms and hurricanes. Large scale restoration activities are happening less. sustainable approach to mangrove forest restoration. mangrove restoration projects using either approach. This takes a lot of preparation, work and with that money, making this restoration strategy not that feasible. Planting is only necessary if natural recolonization after the hydrologic restoration fails. which limits biodiversity, rather than selecting all the potential species that are appropriate for the site. The costs of individual projects should be calculated on a case-by-case basis, This project involved the expansion of an existing mangrove forest on the seaward side of a dike system estimated planting capital and recurrent costs at approximately US$41 per hectare of mangrove planted, at 2009 price levels. With regard to the presence of suitable sites, it should be noted that clear-cutting of mangrove forests has often led to degradation and erosion of the soil. Established in 2014, it’s one of the world’s longest-running such projects, and has now become the first to use mangrove carbon credits to protect its blue forests. Mangroves flourish by a depositional regime of fine sediments. The objective of this project is to determine if, where, and how mangrove restoration should be implemented in Galveston Bay. Suspended sediments that enters the mangrove ecosystem through waves, settles between the roots of the mangrove trees. The most important is the restoration of abiotic conditions that allow natural development of mangroves. Working with Nature solutions contribute to multifunctional land use, such as nature development, flood risk management, fresh water supply, fisheries, recreation and infrastructure. Many mangrove forests were lost during the last decades of the 20th century. There are different reasons for the reduction of mangroves. Ecological Engineering for Successful Management and Restoration of Mangrove Forests. Furthermore, hand planting tends to ignore variations in soil elevation as planters attempt to keep propagules in straight lines. Working-with-nature is an approach in which optimal use is made of natural dynamics, Restoration is defined as ‘an act of putting or bringing back into a former, normal, or unimpaired state or condition’. Experiments and field observations have provided evidence for the wave attenuating function of mangrove vegetation. This estimate includes planting costs and the cost of thinning (removal of certain plants to improve the growth rate and health of the remaining plants) from year six onwards. CBEMR starts with a detailed investigation of the proposed site to understand the reasons for previous mangrove losses and why mangroves are not naturally regenerating. For example, to gain successful mangrove restoration at a larger scale and to limit uncoordinated fragmented initiatives it is necessary for governments to develop proactive coastal management plans to protect, enhance, restore and create mangrove forests. The reasons for degradation in the first place are often not taken into account and restored before the planting activities start. For successful mangrove restoration the following six steps are identified. The most important is the restoration of abiotic conditions that allow natural development of mangroves. IUCN and The Nature Conservancy are producing a global map with cutting edge analysis on the potential for, and challenges to, mangrove restoration. Reduction/degradation of the mangrove forest results in a loss of these ecosystem functions. This step includes resolving land ownership/use issues necessary for ensuring long-term access to and conservation of the site. The most important is the restoration of abiotic conditions that allow natural development of mangroves (interview B. van Weesenbeeck). Red = Training;  Green = Training & Restoration. Costs of mangrove restoration          The costs of mangrove restoration differ per type of mangrove restoration activity (as proposed by R. Lewis (2001)); The costs of mangrove restoration further depend on: Clearly, estimating the costs of mangrove restoration is complex and depends on a large number of factors. Mangroves are forests in intertidal areas, with medium height trees and shrubs. We elaborate on these three below. Onze website maakt gebruik van cookies om het gebruik en functionaliteit te waarborgen. Mangrove restoration is about recovering the former situation; it is the regeneration of mangrove ecosystems in areas where they were previously situated. Technically, rehabilitation or restoration of mangroves can be surprisingly easy: [ T] he single most important factor in designing a successful mangrove restoration project is determining the normal hydrology (depth, duration and frequency, and of tidal flooding) of existing natural mangrove plant communities ([i.e.,] a reference site) in the area in which you wish to do restoration (Lewis, 2005, p. 409). This research, combined with a study of a nearby natural healthy mangrove, will reveal what has changed on site and what needs to be done in order to restore normal mangrove conditions. The approach they offer, integrates sustainable use with commercial production and reduction of the vulnerability of coastal areas. This is an incentive for them to invest in mangrove restoration and conservation. Wetland habitats (like mangroves) are more dynamic than terrestrial habitats; they’re submerged in water for part of each day as the tides come in and roll out. Adaptive pathways include the use of multiple scenarios on future socio-economic and physical developments (e.g. Benefits of mangrove restorationMangroves are very productive eco-systems; they provide benefits in different ways for many parties. Additional research is needed to build successful business models around mangrove restoration. While governments acknowledge the importance of mangroves, the success of restoration efforts has been limited. However, about 200–220 ha showed successful mangrove restoration. Restoration of ecosystems will seldom reach this initial stage, but it will more often mean returning the ecosystem to a state of effectiveness (Bosire et al, 2001). Infrastructure development and hydrological diversion. World mangrove distribution in 2000 (Wikipedia, 2013), Key words: Mangroves, working with natureDelta Facts: Sand Nourishment, Managed Realignment. They are located mostly along tropical coastlines and some subtropical coastlines (see figure 1). There are a lot of benefits related to mangrove restoration (as stated before), which could, in theory, be commercially exploited. Physical A constraint to successful implementation of mangrove restoration is an incomplete understanding of the ability of a clear-cut, degraded wetland to recover, and of the success rates of mangrove restoration. These are human-induced degradation and natural disturbance related. Natural regeneration has the advantage of not only producing a more biodiverse mangrove, which increases its resilience to climate change, but also potentially more economical as it avoids the costs of nurseries and planting out. The level of survival of the restoration project sites ranged from 0 to 78% and only three sites, that is, Kalpitiya, Pambala, and Negombo, showed a level of survival higher than 50%. Deltares is concerned with several mangrove restoration projects. These ponds are exhausted within a few years and after that abandoned as they are no longer useable. In addition, a crucial condition for successful restoration of mangrove forests is the support and involvement of the local community. The needs of mangroves and other wetland plants and animals are not yet fully understood. Mangroves include about 16 families and 40 to 50 species, but depending on the classification 100 species can be counted (, Mangrove restoration is an activity that fits well in the working with nature concept because mangrove forests serve as natural coastal defence. Therefore, I have developed a rapid assessment monitoring protocol to be incorporated as part of mangrove restoration projects in Southeast Asia in order to evaluate the success of each project and approach and adaptively manage these over time. Human-induced degradation is the active conversion of mangroves by humans, while natural disturbance is degradation of mangroves as a result of a change in their environment/ecology (which can have a human cause as well) (. How MAP can help your organization implement CBEMR techniques, © 2020 Mangrove Action Project. Type and location of mangrove/wetland to be restored, expertise availability, and consequent chances of success, Degree of mangrove/wetland degradation and consequent restoration requirements, Intended degree of restoration (for example, it may not be possible to restore all the ecosystem functions of a wetland if it is located in a highly industrialised/urbanised environment and the planned restoration measures may be less ambitious), Land costs if land purchase is required to convert to wetlands. Coastal wetlands : an integrated ecosystem approach. The tidal movement of water is not disturbed by breakwaters; it is actually the roots of the mangroves that reduce the velocity of the water and capture sediment. Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. The success of restoration through replanting seems to depend largely on availability of suitable sites and species and the involvement of the local community (Walters et al., 2008). 2. It is also key to natural regeneration as the flushing brings in all the available seeds and propagules and puts them in the appropriate place, unlike single-species planting which only produces mono-culture plantations. Pilot projects are running in for example Indonesia will provide further insights. To ensure that the mangrove forests are maintained and used in a sustainable manner (for example not torn or cut), local people and local stakeholders have to be involved in shoreline management. He said the plants will be moved to Number Six from a mangrove nursery manned by residents, as community involvement in the procurement of seedlings extends to ensuring … Nine out of 23 project sites (i.e. There also needs to be an investigation of the social factors that might inhibit mangrove regeneration including land tenure, site usage, site history, what restoration attempts have been tried already, and other relevant socio-economic factors such as livelihoods that impact on mangroves.
