successful mangrove restoration projects

Design the restoration program at suitable sites (selected in step 4) to restore the proper hydrology and utilize natural mangrove recruitment for natural development. 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. Utilize actual planting of propagules or seedlings only when step 1-5 does not work out and natural recruitment will not provide the quantity of successfully established seedlings, rate of stabilization or rate of growth as required for project success. How MAP can help your organization implement CBEMR techniques, © 2020 Mangrove Action Project. Ecological Engineering for Successful Management and Restoration of Mangrove Forests. Experiments and field observations have provided evidence for the wave attenuating function of mangrove vegetation. This also influences the specific mangrove species that will grow at this location (McKee, 2002). 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. IUCN and The Nature Conservancy are producing a global map with cutting edge analysis on the potential for, and challenges to, mangrove restoration. 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. Our experts offer extended training workshops that integrate and address the needs of multiple stakeholders into the process, creating a network that brings a lasting restorative effort, A key component of the CBEMR process is understanding and addressing the underlying ecological necessities of each individual area – fixing the underlying reasons for why mangroves haven’t naturally regenerated in the first place, Working with local communities – including in networking, educational, and livelihood training capacities – is integral to the success of projects, ensuring that those living within the area will be involved in the restoration efforts, countries MAP has given CBEMR trainings to worldwide, CBEMR demonstration sites across Thailand converting abandoned shrimp ponds back to healthy mangroves, villages involved in mangrove restoration knowledge exchange projects, Click the link below to download a PDF to learn a bit more about the CBEMR process, Locations of CBEMR trainings & restorations around the globe. World mangrove distribution in 2000 (Wikipedia, 2013), Key words: Mangroves, working with natureDelta Facts: Sand Nourishment, Managed Realignment. Mangrove restoration is based on a strategy of ‘working with nature’. Monitoring of completed schemes will enhance the understanding of the mangrove restoration (Climate tech wiki, 2013). Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. The process will also hopefully demonstrate that local communities must preserve the mangroves they have, protect them, and manage them sustainably in order to secure a sustainable future for themselves. 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. 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 are capable of protecting the coastline against erosion caused by wind, waves, and currents, and they can reduce the impact of storms and hurricanes. In the past decades a lot of experience has been gained with mangrove restoration in tropical areas. MAP suggests that as nature does not grow in straight lines, there is no need to plant mangroves like this – planting in lines and even spacing is a terrestrial production forestry approach. 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. There is a big step to be made to upscale small restoration activities. Mangrove forests are situated in the intertidal area between land and sea. Wetlands International, IUCN Netherlands, Oxfam Novib – Sustianable Shrimp Production South East Asia. The coastal restoration site before and after Hurricane Irma. Additional research is needed to build successful business models around mangrove restoration. They are located mostly along tropical coastlines and some subtropical coastlines (see figure 1). The study, Have mangrove restoration projects … Different parties can use the mangrove ecosystem as a resource for producing products and services. MAP also facilitates a CBEMR e-group with over 280 members worldwide sharing information and experience on more effective ways to rehabilitate mangroves. Implementing a successful method of mangrove restoration. There are a lot of benefits related to mangrove restoration (as stated before), which could, in theory, be commercially exploited. 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. On-going researchAs stated before, much is learned by doing. 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 theoretical business models should be tested and further expanded. The human factor in mangrove restoration should not be underestimated (Bosire et al., 2008). 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. The level of survival of the restoration project sites ranged from 0 to 78% and only three sites, that is, The needs of mangroves and other wetland plants and animals are not yet fully understood. For successful mangrove restoration the following six steps are identified. An international database of mangrove restoration projects would reduce the likelihood that unsuccessful restoration projects would be repeated elsewhere. about 200–220ha showed successful mangrove restoration. An illustrative example is the story of a village in India’s province Tamil Nadu, In an attempt to get in the Guinness World Records book the inhabitants planted 80.244 saplings of mangroves. 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. Hydrologic restoration (with and without planting). In the past decades a lot of experience has been gained with mangrove restoration in tropical areas. At the same time, this fact only makes successful mangrove restoration even more urgent. There are different reasons for the reduction of mangroves. This makes it very difficult to restore the mangrove forests. Natural regeneration is preferred, as the resulted forest is supposed to be more like the original forest (, Excavation or fill; In order for mangroves to grow, the restoration site needs to have a certain slope and a very exact tidal elevation to insure that the hydrology for the mangroves is correct. Coastal wetlands : an integrated ecosystem approach. 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. Meer informatie hierover vindt u op onze, Mangrove forests are estuarine wetlands, the area where the river meets the sea. (Tri et al., 1998). Good hydrology is vital for a healthy functioning mangrove and the provision of the full suite of ecosystem services. Scientific data shows that when this method is used, the ecological functions of the mangrove forest are quickly restored. 36/67 planting efforts) showed no surviving plants. Mangrove … The reasons for degradation in the first place are often not taken into account and restored before the planting activities start. Many effective mangrove restoration projects, like the mentioned one in South India, have been conducted through an approach of ‘learning by doing’. Understand the normal local hydrology that controls the distribution, settlement and growth of mangrove species. 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. Planting alone; inexpensive, from 100-200USD/ha. MAP suggests that as nature does not grow in straight lines, there is no need to plant mangroves like this – planting in lines and even spacing is a terrestrial production forestry approach. Large scale restoration activities are happening less. Working-with-nature is an approach in which optimal use is made of natural dynamics such as wind, water, sediment and vegetation and may lead to a positive effect on nature. 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. 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. World mangrove distribution in 2000 (Wikipedia, 2013), Key words: Mangroves, working with nature. Work together with communities, organizations and local government in order to: Understand the ecology of the naturally occurring mangrove species at the site such as the patterns of reproduction, distribution, and successful seeding establishment. 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”. 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. These activities are initiated from bottom up. Mangrove restoration is based on a strategy of ‘working with nature’. We elaborate on these three below. 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). Furthermore, hand planting tends to ignore variations in soil elevation as planters attempt to keep propagules in straight lines. Governance Next to the physical conditions, the governance setting around the restoration activities is very important. 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). 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. 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. As stated before, much is learned by doing. 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’. Mangroves are very productive eco-systems; they provide benefits in different ways for many parties. The needs of mangroves and other wetland plants and animals are not yet fully understood. 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. Involving local stakeholders right from the outset, this process encourages the mitigation of mangrove stressors and the facilitation of natural regeneration where at all possible. The most important is the restoration of abiotic conditions that allow natural development of mangroves (interview B. van Weesenbeeck). 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 … 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) (. These ponds are exhausted within a few years and after that abandoned as they are no longer useable. 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) (Biswas et al, 2009). This will also reduce or even avoid the cost of restoration and planting schemes. However, over 80% of these projects failed. The project aimed to use the novel PVC encased method to plant the young mangrove propagules- a method that was new to me. In summary, five critical steps are necessary to achieve successful mangrove restoration: 1. Pertinent areas of mangrove ecology, biology and social science are included to combat specific challenges such as very high salinity, or over-harvesting of mangrove wood. Mangrove restoration is about recovering the former situation; it is the regeneration of mangrove ecosystems in areas where they were previously situated. 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. 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 … Still, I was disheartened to hear that while the community may plant 1,000 mangroves in a month, development projects that transforms coastal wetlands could kill the same amount in just a day. 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. Situated between land and sea, the mangrove forest contains many different species which, depending on their location, are more or less salt tolerant. 11As stated above, the majority of mangrove “restoration” projects in this region of the world involve preparing seedlings in polybags or direct root propagules (usually of the genus Rhizophora), which are then hand-planted in straight rows at spacings of less than a metre. Until researchers, NGOs, and government agencies can work together, mangrove restoration has an uncertain future in Sri Lanka. “There was a major restoration project in Saint Lucia, and their shade house is 12 by 14,” she said. Our goal was to inform best-practices for mangrove ( Avicennia germinans) restoration, and to provide recommendations as to if and when coastal wetland restoration efforts should include mangrove plantings. Infrastructure development and hydrological diversion. Furthermore, hand planting tends to ignore variations in soil elevation as planters attempt to keep propagules in straight lines. 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). several preferred methods for planning and implementing mangrove rehabilitation. Next to the physical conditions, the governance setting around the restoration activities is very important. The principal objectives of this project are carbon emission reduction, climate adaptation, and biodiversity conservation.
