Newton RCUK-SEAMED - Harnessing multiple benefits from resilient mangrove systems
Lead Research Organisation:
University of Leeds
Department Name: School of Earth and Environment
Abstract
Mangroves provide multiple benefits from carbon storage and shoreline protection at global and national scales, to food and energy for natural resource-dependent coastal communities at local scale. However, mangroves are coming under increasing pressure due to land use changes resulting from climate change, coastal development and aquaculture. In Vietnam the area under mangrove forest declined by 35% between 1983 and 2012, increasing vulnerability of the coast to tidal surges, hurricanes and saline intrusion as well as reducing the availability and accessibility of mangrove resources necessary to support livelihoods. Previous research in Vietnam has taken a largely technical approach to the relationship between mangrove protection, restoration and aquaculture and has not paid adequate attention to socio-economic factors. This research aims to evaluate socio-ecological resilience in Vietnamese mangroves in the Red River Delta and evaluate management options to enhance delivery of benefits and services across multiple scales, using an interdisciplinary approach that incorporates ecology; remote sensing and GIS; and social research methods on livelihoods and scenario evaluation. By doing so, this research will contribute to a) the livelihoods and resilience of mangrove dependent communities, b) the on-going delivery of ecosystem services across scales, while at the same time c) through stakeholder engagement and knowledge exchange throughout, building the capacity for conservation and sustainable management of mangroves in Vietnam.
Planned Impact
The overall impact of the research is enhanced management of mangrove social-ecological systems to deliver ecosystem services across scales. We have identified a range of stakeholders who will benefit from the research in a number of different ways. These are outlined below. The timeframe over which we envisage benefits is indicated using L = long term; M = medium term; and S= short term.
1. Mangrove-dependent communities will benefit through:
- Enhanced participation of different stakeholders in mangrove governance (M/L)
- Improved diversity, heterogeneity and sustainability of livelihoods and the landscape (L);
- Improved delivery of key ecosystem services (L);
- Overall enhanced quality of life (L)
2. Policymakers (national and other levels) will benefit through:
- Enhanced awareness of ecosystem services delivered by mangrove socio-ecological systems (S/M);
- Improved integrated interdisciplinary knowledge base to inform evidence-based policymaking (M);
- Improved effectiveness of public policies on coastal and wetland management (L);
3. NGOs and other agencies (e.g. ICRAF)
- Increased access and availability of data on the study areas (M);
- Improved interdisciplinary approaches for resource management and ecosystem service delivery (L);
4. Development donors (e.g. DfID, GIZ)
- Decreased need for development aid in the study areas over the longer term (potentially leading to reprioritisation of focal areas) (L)
- Specifically, in line with DfID's climate and environment priorities and of particular relevance to investments in Tanzania:
- Enhanced understanding of how people can adapt to the effects of climate change on their lives and livelihoods (S/M)
- Improved evidence base for how the world's forests and the livelihoods of the 1.2 billion people who depend on them can be enhanced (S/M)
- Improved effectiveness of public policies on coastal and wetland management, supporting the UK Government's promotion of good governance (L)
5. Academics - See academic beneficiaries section
The kinds of potential impacts we envisage are often overlapping. In an ideal scenario, benefits for one stakeholder group support and feed into the delivery of wider benefits for another. For instance, improved effectiveness of public policies on coastal and wetland management at the level of national policy stakeholders will also support the goals of country-level and international donors. Finally, there are less tangible benefits for global society which the research can help to deliver. Healthy, functioning, resilient mangrove systems, which are managed for multiple purposes, will continue to sequester carbon from the atmosphere. Thus, the research can also contribute towards climate change mitigation.

Description | Remote sensing is an effective tool to extract useful information about mangrove extent and species. Data collected from standard plots in mangrove communities was used to improve the reliability and accuracy of the estimates of the biophysical mapping of the mangrove forest including above ground biomass estimation, forest classification and estimates of the forest age. In addition, information on mangrove biomass and age could be derived from remote sensing data which is also strongly correlated with mangrove health. Mangroves of similar ages inside and outside of the outer dike showed differences in biomass, regeneration, and density, suggesting the dike has positively affected mangroves on the landward side, and negatively affected mangroves on the seaward side. However, mangrove regeneration inside the dike appears negatively affected. The research developed an innovative approach to understanding social values of mangroves using participatory GIS. We found that protection from storms was the ecosystem service valued most by all local groups of people because of security benefits to the sea dike, lives and assets, and freedom from fear and worry. Food, sediment accumulation and habitat provisioning were also of high value to all. The provision of places for learning, water quality regulation, spiritual association and the fuelwood were of least importance. Our scenarios work showed that under a conservation scenario values attached to places supplying services currently important may be substantially altered. In some cases, restrictions on access to areas perceived as important now may lead to reduction in their value. This implies that values attached to the forest may depend on formal access rights, even if the benefit received is not clearly linked directly to physical access. |
Exploitation Route | Land building and ecosystem service hotspots, and their relation to local livelihoods, will have important implications for management and planning across the Red River Delta. If this new knowledge is taken up by government planning, environment and agriculture departments then they will influence how, why and where mangrove projects for planting and conservation are implemented, where development along the coast might be implemented, and by the inclusion of mangrove contributions to livelihoods and local economic development in planning processes. Our work developing an mangrove webGIS tool should facilitate this process. |

Description | The project has had an impact in terms of Outcome 2 of our pathways to impact, research capacity - academics, research students: Significantly increased capacity of co-Is and research students in addressing interdisciplinary challenges (linked to SDG 4). A female masters student has completed their masters thesis based on field data collected with this project. The student received training and support in the field and then guidance on their analysis from the research team. Research training has been provided for all members of the project team based in Vietnam, in stakeholder analysis, participatory methods and ecosystem services. This has increased the capacity of these team members to engage with the research project, but also to conduct collaborative and multi-disciplinary research. Research training for a wider group of researchers (academics and students) based in CRES Vietnam has been provided in using GIS for social research. Mentoring and support of the PI has increased their capacity to manage the project. This project has two female co-PI's, and two other female co-I's leading work packages (4 out of a total of 5 academic staff on the project) and has employed a female PDRA on the project. As a result the project is building the capacity of female researchers and academics in this field, both in Vietnam and in the UK (SDG 5). A webGIS training event for local stakeholders was held in 2020 (outcome 4) and a policy workshop was held in Hanoi at the end of 2020 (outcome 3). A suite of policy briefs was developed in support of these activities. Currently 7 papers have been published as a result of work on this project. The policy briefs and policy workshop were the main ways the project intended to influence policy processes in Vietnam. New knowledge and tools developed in the project were made available to policy makers to support decision making on economic development planning and conservation in mangrove areas. Key policy makers in government ministries were engaged in the project from the beginning (through meetings) and in the final training event and policy workshop. There is interest in how the spatial products produced by this project (particularly webGIS), can be used in policy and planning processes. |
