A Review of SAR Image Processing for Mangrove above Ground Biomass Estimation

Mangrove biomass monitoring has become critical today, as it aids in measuring the amount of carbon that will be contained in these forests in the future. Remote sensing is possibly the solution for estimating AGB on a large scale. It allows biomass assessments over large areas, providing a spatially comprehensive measure of forest biomass variance in a relatively short time and at a low cost. Because of the penetration capability of radar remote sensors, the high-frequency L-band and P-band can be used to measure aboveground biomass effectively. The study emphasizes the importance of Synthetic Aperture Radar imaging and the correlation between backscatter reflectance of remotely sensed data and live biomass over a given area. Despite many studies on the use of machine learning algorithms for biomass estimation, no single model fits all problems. Furthermore, finding the best machine learning model is critical for advancing global expertise in the field of mangrove forest management. The hybrid models such as extreme gradient boosting regression (XGBR) and extreme Gradient Boosting (XBoost) are also used along with regression models linear regression, multilayer perceptron (MLP), and machine learning approaches like support vector Machine (SVM), random and random forest (RF) is used in mangrove studies. In comparison to the allometric equations based on ground truth data, remote sensing methods are coming up as an effective tool for AGB estimation of mangroves. This vision survey focuses on SAR radar remote sensing-based studies in mangrove forest biomass estimation and the limitation of SAR imaging in AGB estimation.

Abstract. Sabrina AD, Ramadhandi AR, Nur AAI, Liza N, Sutarno, Yap CK, Indrawan M, Setyawan AD. 2022. Sustainability level of mangrove forest management based on RAP-MForest approach in Pancer Cengkrong, Trenggalek District, Indonesia. Intl J Bonorowo Wetlands 12: 82-88. Mangrove forest area is a coastal resource that benefits the community's welfare. Protection and preservation of the mangrove ecosystem need to be carried out by taking into account various aspects to achieve sustainability. This study aims to analyze the level of sustainability of mangrove forest management and the contributing factors in the Pancer Cengkrong Mangrove Forest area in Karanggandu Village, Trenggalek District, East Java, Indonesia. This research was conducted in June 2022 through field interviews and literature studies. Three dimensions (ecological, economic, and social) were selected, along with their attributes. Each attribute was scored to indicate the status of sustainability. Then, the data obtained were processed by Multi-Dimensional Scaling (MDS) analysis using the Rapid Appraisal for Mangrove Forest (RAP-MForest) method. Furthermore, leverage analysis determines the sensitive attributes in each dimension. The results depicted that management in Pancer Cengkrong Mangrove Forest is less sustainable in the economic dimension and fairly sustainable in the two remaining dimensions. The social dimension achieved the highest sustainability index value at 72.92. Furthermore, knowledge of the sustainability index and sensitive factors can help provide recommendations for management in the Pancer Cengkrong mangrove area to achieve a sustainable level. In this case, the economic dimension should be more concerned with promoting environmentally sustainable development.

Characteristics of integrated mangrove-shrimp farming systems in Ben Tre Province, Vietnam: preliminary findings for organic shrimp production certification

Mangrove forests play a critical role in natural disaster resistance and provide meaningful livelihoods for local communities, especially integrated mangrove shrimp farming (IMSF) systems. Organic shrimp certification actually increases the value chains of shrimp farming in addition to ameliorating mangrove–forest management. Identifying technical issues and assessing environmental risks are the leading concerns when considering organic shrimp production certification. In this study, the technical practices of 30 households were investigated, and surface water and sediment samples were collected in the IMSF models and adjacent rivers in the Thua Duc Forest Management Board area, Ben Tre Province. Data collected from shrimp farming ponds and the environmental background were referred to both the Naturland and National Standards. The results showed that the average mangrove forest and shrimp pond ratio was 56.90:42.70 (%). Two technical issues were highlighted: (i) the use of rotenone, known as a toxin to kill undesirable fish before stocking shrimp, and (ii) annual shrimp pond regeneration causing increased pollution. The data showed that higher concentrations of TSS and P-PO4 3- were detected in surrounding rivers, while surface water in either IMSF ponds or adjacent rivers slightly surpassed the permissible levels of total Fe concentration. All parameters—including heavy metals; toxic and persistent parameters; oil and grease and coliforms analysed in surface water, and sediment samples—were lower than the detection and permissible levels. The results provided evidence that the IMSF’s practices and environmental characteristics were suitable for recommending the Naturland Standards. Recommendations and technical interventions for farmers are necessary to help reduce Fe levels and the safe use of rotenone in IMSF systems. An environmental quality monitoring programme at the target area should be applied when launching organic shrimp production.

The Trend in Types of Tree Damage in Mangrove Forest Management Areas, East Lampung Regency

Damage to mangrove trees is one of them influenced by the types of tree damage. The more types of tree damage to a single mangrove tree, the worse the health level of the mangrove tree will be. This study aims to obtain damage index trend values and types of tree damage in the east coast mangrove forest area, East Lampung Regency. Measurement of the types of damage to mangrove trees was carried out three times using the Forest Health Monitoring (FHM) method in two FHM cluster plots for each mangrove forest area. Assessment of damage to mangrove trees uses the Damage Index formula. The results showed that the trend index values for mangrove tree damage were 9.3 and 4.5 (Resort Kuala Penet, Way Kambas National Park), 9.2 and 19.8 (Margasari, Labuhan Maringgai), and 6.2. and 9.8 (Purworejo, Pasir Sakti) with the dominant types of damage being open wounds (code 03) 343 damage, damaged foliage/shoots (code 24) 240 damage, and broken/dead (code 22) 158 damage. Thus, the trend of damage index and types of damage to mangrove trees in the east coast mangrove forest area of East Lampung Regency has increased.

Evaluation of Ecosystem Services and Mangrove Management Based on the Blue Economy Approach of Untung Jawa Island

Mangrove forests have a very important role for people's lives, especially for people who live in coastal areas, both from environmental, economic and social aspects. However, the economic potential of the ecosystem services provided by mangrove forests has not been comprehensively calculated. As a result, the economic potential of mangrove forests in an area is often calculated to be lower than the actual economic potential. The purpose of this research is to evaluate the total economic potential of mangrove forest ecosystem services. The economic valuation method of ecosystem services used in this study is the Total Economic Value method, including the economic value of providing services, regulatory services, cultural services, and supporting services. The location of this research is on Untung Jawa Island, Seribu Islands, DKI Jakarta Province, while the research time is from July to September 2022. The data used in determining the economic value in this study are primary data and secondary data. The results of the analysis show that the total economic value of the provision of services is around IDR 607 million per year, support services around IDR 15 million per year, cultural services around IDR 1.3 billion per year, and regulatory services around IDR 34 billion per year. The findings of this study have implications that the government and related stakeholders are required to provide more intensive education to the public about the importance of sustainable management of mangrove forests for the development of a blue economy on the island.

Insights into Bacterial Communities and Diversity of Mangrove Forest Soils along the Upper Gulf of Thailand in Response to Environmental Factors.

The comprehensive data for the dynamic adaptation of bacterial community structure in response to environmental factors is important for the maintenance of the mangrove ecosystem. This aspect was investigated with soils and surface water from six mangrove forests in six provinces along the Upper Gulf of Thailand shoreline. Mangrove soils were variable with respect to pH (acidic to slightly alkaline) and had low amounts of organic matter (OM). Illumina next-generation sequencing attested that the number of observed species as well as the bacterial diversity and richness among all sites were not significantly different. The gamma-, alpha-Proteobacteria, Desulfobacteria, Bacteroidia, Anaerolineae, Bathyarchaeia, Acidobacteriae, Nitrososphaeria, Clostridia, and Thermoplasmata were more abundant bacterial classes present in all sites. Soil OM was the major factor that mostly modulated the bacterial community structure, while salinity influenced the number of observed species and bacterial richness. These results provide informative data on the bacterial community, in response to both environmental factors and heavy metal pollutants, that is prominent for sustainable development and management of mangrove forests.

Mangrove Forest Management Stakeholder Social Network in Langkat Regency

This study examines the social network of stakeholders managing mangrove forests sustainably in Langkat Regency. The existing conditions that have occurred so far show that the government has yet to be able to synergize with stakeholders through a mangrove forest management program that involves local community participation in a sustainable, synergistic, and systemic manner. Identifying stakeholder networks is very important to become a reference in designing a systemic and sustainable mangrove forest management program. Stakeholders who manage mangrove forests in Lubuk Kertang Village and Pasar Rawa Village form a symmetrical relationship through participatory group partnerships. The existing network forms, including tenure aspects (forest land tenure rights), and social and economic constructions, provide a significant background and influence on efforts to rehabilitate degraded mangrove forests. Within this scope, social networks can be understood to determine access rights, management rights, and governance of mangrove forests. The purpose of this research is to find out the shape of the network and the role of stakeholders (actors and institutions) as managers of mangrove forests. The method used is qualitative, with descriptive analysis techniques to analyze the shape of the network and the role of stakeholders (actors and institutions) as managers of mangrove forests.

Factors Affecting Community Participation in Environmental Corporate Social Responsibility Projects: Evidence from Mangrove Forest Management Project

Community participation in an environmental corporate social responsibility (CSR) project can help business enterprises effectively develop projects that respond to the actual demands of the community and effectively utilize a firm’s resources. This study aims to investigate factors that affect community participation in each stage of environmental corporate social responsibility project development. The environmental corporate social responsibility project explored in this study is a sustainable mangrove forest management project in the Pakprasae sub-district of Rayong province in Thailand. This study has tested whether enterprise-related factors (such as perceived CSR credibility and organization–public relationship (OPR) quality) and participant-related factors (such as ecological knowledge, perceived ecological values, and expected benefits from participation in the project, both monetary and non-monetary related benefits) could predict community participation in an environmental corporate social responsibility project development initiated by a business enterprise. Questionnaire surveys were administered to 355 community members who were the target group of this environmental corporate social responsibility project from June to July 2022. The collected data were inspected and analyzed using an inferential statistical technique. Multiple regression analyses were performed to test significant factors that affected community members’ participation in planning, implementing, and monitoring the project. The results revealed that perceived ecological values were the strongest predictor of participation in all stages of the project, including planning, implementing, and monitoring the project. Perceived CSR credibility and OPR quality also significantly affected participation in all stages, whereas ecological knowledge significantly affected participation only in the monitoring stage. These findings suggest that to promote community participation in each stage of environmental corporate social responsibility project development, it is important to enhance community members’ perceived ecological values, and community members should be educated in ecology to enhance participation in the monitoring stage.

Influence of mangrove forests on subjective and psychological wellbeing of coastal communities: Case studies in Malaysia and Indonesia.

Mangrove forests possess multiple functions for the environment and society through their valuable ecosystem services. Along with this, the mangrove forests have large and diverse social values, in combination contributing to the health and wellbeing of the surrounding communities. This study aims (i) to assess the benefits of mangrove forests and their impact on subjective and psychological wellbeing of coastal communities and (ii) to understand the challenges coastal communities face that limit sustainable wellbeing. We have used a mixed methodological approach, combining workshop, interview, and survey, to obtain qualitative and quantitative information from two coastal communities in Malaysia and Indonesia. For quantitative data, 67 participants from both coastal communities participated using a pre-tested structured questionnaire. To obtain opinions from key informants in Malaysia and Indonesia, we organized two stakeholders' workshops and community interviews. When merging these interviews and workshops, we identified the following three themes related to the perception of mangrove forest benefits: (1) the advantage of living in a natural countryside; (2) the natural resources supporting employment, income, and family security; and (3) the increase in subjective and psychological wellbeing. The mean score of wellbeing for Indonesian participants (28.6) was slightly higher than that for Malaysian participants (26.2) and was significant. Overall, the respondents felt happy because the combination of job security and leisure activities supports feeling content and satisfied. The analyses also suggest that the combination of exposure to coastal environments and stress reduction promotes good mental health; however, diagnostic health data are lacking. The lower score of mental wellbeing in Malaysia is attributed to respondents involved in risky fishing activities and local regions with excessive tourism. The findings from this study imply that coastal mangrove forest management plays an important role in the living conditions of coastal communities and their subjective and psychological wellbeing. Hence, restoration and sustainability of mangrove ecosystem are important.

Local community perception on the State Governance of mangroves in Western Indian coast of Kinondoni and Bagamoyo, Tanzania

Sustainable conservation of mangrove forests has been constrained by marginalising some key stakeholders in resource governance in Tanzania. The present study assessed the perceptions of local communities towards the state management of mangroves on the western Indian coast of Kinondoni and Bagamoyo. The mixed method design was used to collect data from 306 respondents from Kaole, Mlingotin, Pwani-Kunduchi, and Mtongani villages via household questionnaire surveys, interviews with key informants, focus group discussions, and documentary reviews. The overall mean score on a 5-point scale for respondents in both study sites was 3, indicating neutral perception. The perception of respondents towards state management of mangroves for ecological benefits was relatively higher (M = 3.92, SD = 0.18) than for socioeconomic context (M = 3.02, SD = 1.03), t (128) = 4.7, p < 0.01, d = 0.51) in Kinondoni. The same results were revealed in Bagamoyo as higher perception for ecological gain (M = 3.43, SD = 0.67) than for economic benefits (M = 2.63, SD = 0.86), t (133) = 5.3, p < 0.01, d = 0.63. Multiple regression models revealed that local community perceptions of state management of mangrove forests in both study areas can be explained by education level (β = 0.168, p = 0.012), knowledge of reserve rules (β = 0.187, p = 0.013), household distance from reserve boundary (β = 0.798, p = 0.003), and occupation (β = −0.162, p = 0.001). The study revealed that respondents were satisfied with the state’s management of mangroves for ecological gain, but they were not supportive of management when economic issues were discussed. The study recommends the state management of mangroves to become inclusive and recognize the neighboring communities’ entitlements; an adequate contribution of revenue from mangrove protection to local livelihood; and the provision of environmental education to communities on the potential of ecosystem services to increase their social acceptability.

The Management Strategy of Ecopreneurship-based Sustainable Mangrove Forest Ecotourism in Makassar City, South Sulawesi

Mangrove forests provide various tropical and subtropical ecosystem services to support sustainable development and people's livelihoods. Ecopreuneurship-based management became an alternative approach for mangrove forests ecotourism. Implementing the ecopreneurship concept in mangrove forest areas could include the utilization of mangrove forest products for business while maintaining biodiversity and the environmental sustainability of the ecosystem. This research aimed to formulate the strategy for ecopreneurship-based management of mangrove forests. This research employed direct observation and in-depth interviews. The respondents were purposively selected based on their specific roles within the communities, community leaders, local governments, and non-governmental organizations surrounding the mangrove forest areas. This research applied SWOT (Strengths, Weaknesses, Opportunities, and Threats) method to analyze the ecopreneurship-based mangrove ecotourism management in Makassar City. The SWOT analysis resulted in three strategies to capture the available opportunities. First, developing community business through innovations in local resource utilization. Second, empowering the community groups such as fishermen, farmers, and women to create mangrove-based household scale businesses. Third, providing training on the post-harvesting mangrove forest products and digital/ online marketing for brown sugar.

Dynamique spatio-temporelle de la forêt de mangrove dans la province de Trat en Thaïlande

In the United Nations 2021–2030 ecosystem restoration programme, coastal ecosystems such as mangroves are listed as a priority for biodiversity restoration. Therefore, understanding mangrove species diversity and changes over time are essential to predict ecosystem health, viability and resilience to changing climatic and human pressures. However, when considering future conservation ambitions and policies for mangroves, it is also crucial to understand the effects of conservation interventions. To address these concerns, we needed to develop reliable inventory methods for mangrove forests, spatialised predictions of biodiversity and good practices for using Earth observation data. In this study, we investigated the gaps in knowledge concerning the spatial organisation, intertidal zones and the recent history of mangroves in Thailand's Trat province. We investigated the impacts on forest diversification of environmental parameters, such as topography, and of human interventions such as stand rehabilitation or plantations. We were able to integrate historical multi-satellite data, current ecological data and micro-topographic measurements to establish the status and describe the spatial organisation of the mangrove forests in the Province of Trat. Using the method described in this study, we were able to overcome the technical limitations of monitoring protocols and thus develop a powerful decision-support system to assess the recovery period of mangrove forests, their structural growth and the species composition of plantations and natural native stands over three decades. Our study also identifies the main influencing factors that compromise the quality of Earth observation data, and proposes specific best practices for monitoring mangrove ecosystems. In addition, we developed the ARMA tool (Automatic Regrowth Monitoring Algorithm) and summarized functional indicators (secondary succession) by type of stand. ARMA can identify the years of planting, recovery period, age and structural development of rehabilitated mangroves compared to adjacent natural and naturally regenerating mangroves. We believe that our study makes a significant contribution to research on mangrove biodiversity, as it has several potential applications for forest restoration planning and management. It can therefore be a useful tool to measure and assess biodiversity and thereby improve ecosystem-based mangrove forest management.
