A contemporary analysis of policy implementation for the coastal mangrove forest management in Bangladesh Sundarbans

Despite having more than 200 environmental laws and policies in Bangladesh, the overall ecological situation is almost beyond control. Relying on both primary and secondary sources of data, particularly the legal texts, this study delves into analysing the legal frameworks of Bangladesh pertaining to wildlife and biodiversity conservation in the Sundarbans mangrove forest (SMF). This study finds that the lack of implementation of stringent provisions is one of the key reasons for the failure to successfully conserve biological diversity in the SMF. The other reason that heavily accelerates environmental crimes in Bangladesh is the less severe punishment compared to other crimes. This study result reveals that the Animal Welfare Act 2019 imposes a mere BDT 10,000 (USD 116) for harming any animal. This study also finds that the Environment Court Act 2010 strives to expand environmental governance in every district, but the absolute authority of the Department of Environment (DoE) and its limited resources hinder such lavish expansion. Although the government has revised many outdated laws and policies and enacted new laws such as Bangladesh Environment Conservation Act 1995 (2023), Forest Act 2023, and Forest Conservation Act 2023, evidence indicates that most of the provisions were not successfully implemented due to overlaps with other laws and loopholes within the laws. In addition, complex bureaucratic systems significantly hamper the administration system in forest management. Furthermore, the Director General (DG) of the DoE’s sole authority often sparked concerns regarding the transparency and accountability of this department. Therefore, this paper examines the domestic legal system of Bangladesh for conserving biodiversity in the SMF.

Essential Ecosystem Area Policies as a Means to Promote Participatory and Inclusive Conservation in Forest Landscape Governance: Centering Perspectives of Marginalized Women in Taman Kili-Kili, Indonesia

This study analyses dimensions of participatory forest landscape governance of the Essential Ecosystem Area (EEA) of Taman Kili-Kili, Indonesia. The voices of marginalized communities, and especially women, are rarely incorporated into forest landscape governance and conservation policies. The recently established Indonesian EEA policy mandates a participatory approach, with explicit requirements to involve marginalized groups and gendered perspectives. However, on a practical level, policy formulation and application unfold in very different ways. Using a Postcolonial Feminist Participatory Action Research (PFPAR) approach, we center local communities' power relations in our analysis as a specific means for drawing out various intersectional relations to conservation areas. The study found that local communities around EEA Taman Kili-Kili have a clear interest in participating in inclusive mangrove forest management models as they not only have the knowledge and capacity, outcomes significantly affect their lives and livelihoods. Findings suggest that the activism of local communities, specifically in the form of various women's gatherings, is reshaping policy milestones and opening up pathways towards gender and ecological justice.

Health analysis of mangrove forest based on vitality indicators (case study in Purworejo mangrove forest, Pasir Sakti District, East Lampung Regency)

Vitality indicators are characterized by tree damage and canopy condition. This condition has an impact on the health of mangrove forests, including the Purworejo mangrove forest. The aim of this research is to obtain the value and health status of the Purworejo mangrove forest in Pasir Sakti District, East Lampung Regency, based on vitality indicators. In terms of collecting and analyzing vitality indicator data, the Forest Health Monitoring (FHM) method is used based on tree damage parameters and canopy cover conditions. Sample plot clusters were made into four clusters, or 16 plots, at four points with an area of 0.4 ha per cluster. The research results showed that the tree damage value at the cluster plot level (CLI) was 1.08–1.23. The cluster plot level canopy condition value (VCR) was 2.82–3.32. Thus, the average health value of the Purworejo mangrove forest is 1.88, with a medium status category (1.63-2.31). Mangrove forest management must be improved, especially in maintenance activities, to overcome pest problems that cause damage to mangrove trees.

Local Institutional Collaboration Models for Coastal Communities in North Sumatra

The social network of those managing mangrove forests sustainably in the districts of Langkat and Batu Bara is the subject of this study. The state of affairs indicates that the government has not been able to collaborate with stakeholders on mangrove forest management projects involving the local community that are systematic, synergistic, and sustainable. Finding a network of stakeholders is crucial to designing a mangrove forest management program holistically and sustainably. Stakeholders in the Nibung Hangus Sub-district, Batu Bara Regency, namely Lubuk Kertang Village, Pasar Rawa Village, Tapak Kuda Village, and Bagan Baru Village, maintain mangrove forests symmetrically through cooperative efforts. Rehabilitating degraded mangrove forests is heavily impacted by the structure of current networks, which includes social and economic construction and tenure components or rights to forest property. This research aims to determine the structure of networks and the function of stakeholders—actors and institutions—in managing mangrove forests. Descriptive analytic approaches were employed in the qualitative conduct of this study.

Assessing the Productivity of the Matang Mangrove Forest Reserve: Review of One of the Best-Managed Mangrove Forests

Mangrove ecosystems are crucial for biodiversity and coastal protection but face threats from climate change and human activities. This review assesses the productivity of the Matang Mangrove Forest Reserve (MMFR) in Malaysia, which is recognised as one of the best-managed mangrove forests, while also addressing challenges such as deforestation and climate change-induced factors. This review explores the concept of productivity in mangrove forests, highlighting their role in carbon sequestration and discussing litterfall measurements as fundamental metrics for assessing primary productivity. An analysis of historical changes in MMFR’s biomass and productivity revealed fluctuations influenced by logging, reforestation, and climatic conditions. Trends in MMFR productivity indicate a concerning decline attributed to anthropogenic activities such as aquaculture and industrial projects. A regression analysis conducted on Rhizophora apiculata data with age as the predictor and AGB as the response variable indicated a positive trend (slope = 3.61, R-squared = 0.686), suggesting a quantitative increase in AGB with age. Further analysis revealed a significant negative trend in MMFR’s overall productivity over years (coefficient = −3.974, p < 0.05) with a strong inverse relationship (rho = −0.818, p < 0.05), indicating declining AGB trends. Despite these challenges, this review underscores the significance of sustainable management practices, effective conservation efforts, and community engagement in maintaining mangrove ecosystem health and productivity. In conclusion, sharing management lessons from MMFR can contribute to global conservation and sustainable mangrove forest management efforts, fostering resilience in these vital ecosystems.

What factors influence women’s participation in co-management? A case study of Sundarban mangrove forest management in Bangladesh

Understanding what factors influence women’s participation in forest co-management is vital for effective policy planning and women’s empowerment. The views of women and men from four villages in the Chandpai forest range on what influences women’s participation in forest co-management were gathered qualitatively. Data were collected through focus group discussions (n = 16) and in-depth interviews with key informants (n = 29), and thematically analyzed. The participation of women in forest co-management was mostly influenced by family expectations, then religious and societal norms. Women stated that these expectations constrained their participation, whereas men suggested it was less influential. Men reported that women’s participation was motivated by a sense of responsibility to protect the forest, while women reported that participation was mainly focused on economic security for the family. Activities to increase women’s participation could include training (e.g. forest protection, leadership), awareness campaigns regarding women’s roles, and gender-balanced involvement in household activities.

Monitoring dynamic mangrove landscape patterns in China: Effects of natural and anthropogenic forcings during 1985–2020

Many mangrove forests located along estuaries and deltas worldwide are currently facing irreparable losses caused by natural factors and intensive anthropogenic disturbances. The limited capabilities of traditional remote sensing processing platforms tend to lead to poor image processing consistency in medium- and large-scale areas, resulting in lower ground object classification accuracy. Consequently, little information is available regarding the extent and causes of variation in large-scale mangrove forests. In this study, we used Google Earth Engine mangrove forest data from eight periods between 1985 and 2020, with total accuracy rates of 82.95–90.15%, and combined landscape metrics with a centroid transfer model to quantitatively analyze the landscape evolution of mangrove forests in China. Finally, we employed a geodetector based on optimized parameters to quantitatively determine the potential mechanisms driving mangrove landscape evolution. Overall, a slight increase followed by a sharp decrease in mangrove forest area in China during the past 40 years, with a turning point around 2000 and substantial shifts in mangrove spatial patterns in Guangdong and Guangxi Provinces, particularly in the Pearl River Estuary and Beibu Gulf. The landscape pattern of Chinese mangrove forests has become fragmented and isolated through rapid urbanization in recent decades. Mangrove forests shifted significantly (> 31 km) early in the study period, followed by smaller shifts later in the study period. The optimal spatial scale of mangrove landscape driver detection was 270 m × 270 m. The variation in mangrove forest area was caused by the interactions of multiple factors, particularly between mean annual precipitation and other potential influencing factors. Government policies guided the conservation and management of mangrove forests in China to varying degrees throughout the study period. Our findings on the dynamics of mangrove forests provide a reference for integrated coastal management, which will contribute to the ecological utilization and high-quality development of coasts during extensive urbanization along the southeastern coast of China and similar large estuary deltas worldwide.

Local Institutions Performance in Mangrove Forest Management on Small Islands: Case Study in Buano Island, Maluku Province, Indonesia

Mangrove forests on small islands play an essential role in the stability of island ecosystems. It is crucial to analyze the performance of local institutions in forest management to increase the community’s active role in preserving mangrove forests. This research aims to analyze the performance of local institutions managing mangroves on small islands. The research was conducted on Buano Island, Maluku, Indonesia. In-depth interviews and participant observation were used to obtain data. Data analysis uses a Situation, Structure, Behavior, and Performance (SSBP) approach. The research results show that the community is very dependent on mangrove forests. Resources are owned by the clan group (Soa) but managed by members of the clan group (family). Thus, the phenomenon occurs when common pool resources are managed by private (Dati/Nuru) proprietors. The community regulates the utilization of potential forest resources by dividing management areas controlled by each Soa/Nuru group. The preservation of natural potential on Buano Island is supervised by Kewang and Sasi culture. Applying customary rules increases the community’s active role in managing resources and supporting village management. However, mangrove forest logging activities continue to occur. This performance shows a very high decline in mangrove forest vegetation and regeneration of mangrove forests. Stakeholder support is needed to increase the knowledge and skills of the community, especially traditional leaders, in implementing sustainable forest management.
