Abstract

Climate change has emerged as one of the most pressing global environmental challenges, significantly affecting marine biodiversity, particularly in tropical waters. This study aims to analyze the impact of rising sea temperatures, ocean acidification, and sea-level rise on the diversity and distribution of marine species in tropical regions. Using a systematic literature review and secondary data analysis from 2015–2024, this research synthesizes findings from various case studies across Southeast Asia, the Pacific, and the Indian Ocean. The results indicate that coral reefs, seagrass beds, and mangrove ecosystems are experiencing severe degradation, leading to habitat loss and population decline of key species such as reef fish, mollusks, and marine mammals. Moreover, altered migration patterns and reduced reproductive success are evident among several marine organisms. The discussion highlights how these changes threaten food security, fisheries sustainability, and coastal community livelihoods. In conclusion, climate change poses substantial risks to tropical marine biodiversity, necessitating urgent adaptive management strategies and stronger international cooperation. This research contributes to a deeper understanding of ecological vulnerabilities and emphasizes the need for integrated conservation policies to safeguard marine ecosystems in tropical waters.

Abstract

This study analyzes the quality of seawater and its implications for fisheries productivity along the Indonesian coast. Coastal ecosystems are highly dependent on water quality, which influences the sustainability of fish populations and community livelihoods. The purpose of this research is to assess key water quality parameters such as temperature, salinity, pH, dissolved oxygen, and nutrient concentration, and evaluate their relationship with fishery yields. The study employed a mixed-method approach, combining field measurements with secondary data analysis from environmental and fisheries institutions. Results indicate that declining water quality, particularly due to eutrophication and heavy metal pollution, has significantly reduced fish diversity and productivity in several regions. Conversely, areas with stable environmental conditions exhibited higher fisheries productivity. The findings suggest the urgent need for integrated coastal management policies to ensure sustainable fisheries. This research contributes to a better understanding of the link between marine environmental health and fisheries productivity, providing valuable insights for policymakers, researchers, and local communities.

Abstract

The rapid degradation of coastal ecosystems, particularly mangroves and coral reefs, has become one of the most pressing environmental challenges in tropical regions. Conventional field-based monitoring methods are often limited by high costs, time, and accessibility, especially in remote areas. Satellite technology provides an effective alternative by offering large-scale, continuous, and multi-temporal monitoring of coastal ecosystems. This study aims to evaluate the application of satellite imagery in monitoring changes in mangrove and coral reef ecosystems in tropical regions. A multi-temporal remote sensing approach was employed using high-resolution satellite data, combined with ground truth surveys for validation. Results indicate that satellite technology can accurately detect changes in mangrove cover, identify coral bleaching events, and assess reef health conditions with significant spatial precision. Furthermore, the integration of satellite data with Geographic Information Systems (GIS) enhances ecosystem mapping, temporal trend analysis, and predictive modeling. This study highlights the crucial role of satellite-based monitoring in supporting coastal ecosystem management, conservation planning, and climate change adaptation strategies. The findings suggest that satellite remote sensing is not only efficient but also essential in establishing sustainable management practices for mangroves and coral reefs.

Abstract

This study investigates the water quality of coastal waters in Sanur, Bali, with respect to tourism intensity and domestic wastewater discharge. The Sanur coastline is one of Bali’s major tourist destinations, experiencing high human activity and potential pollution inputs from hotels, restaurants, and residential areas. The objectives of this study were to evaluate key water quality parameters (BOD, nutrients, coliform, turbidity, and DO), to assess spatial and temporal variability, and to determine the relationship between tourism activity and domestic effluent. Water samples were collected from six coastal stations during both peak and off-peak tourism seasons and analyzed according to APHA standard methods. Results showed significant seasonal differences: during peak tourism periods, concentrations of nitrate, phosphate, and coliforms exceeded permissible thresholds, while dissolved oxygen levels decreased. Areas near hotel clusters and domestic drainage outlets showed the most degraded quality. The findings indicate that tourism and domestic wastewater significantly affect Sanur’s coastal water quality. This study emphasizes the urgent need for improved wastewater treatment infrastructure and sustainable tourism management policies to protect Bali’s coastal ecosystem integrity.

Abstract

Coral reefs are essential marine ecosystems that provide habitat, coastal protection, and significant economic value. The Nusa Penida Marine Protected Area (MPA) in Bali has been recognized as one of Indonesia’s most diverse coral ecosystems. However, increasing human activities such as tourism, coastal development, and fishing pressure have affected the health and population dynamics of coral reefs. This study aims to analyze the changes in coral population structure in Nusa Penida as an indicator of marine ecosystem health. Data were collected using line intercept transect (LIT) and photo-quadrat methods at four monitoring sites between 2022–2024. The results show a decline in live coral cover by 8.4% in the last two years, with significant variations across depth gradients and reef zones. Acropora and Porites species dominated shallow areas, while massive coral species exhibited higher resistance to thermal stress. The findings highlight the importance of sustained monitoring and adaptive management to maintain coral resilience. These results provide insights for policymakers and conservation programs in enhancing coral reef restoration and ecosystem-based management in Bali’s marine conservation zones.

Abstract

Sustainable marine fisheries management has become a critical global issue due to the increasing pressure on fish resources caused by overfishing, environmental degradation, and climate change. Indonesia, as one of the world’s largest maritime nations, faces significant challenges in maintaining fish stock resilience while ensuring food security and livelihoods for coastal communities. This study aims to analyze sustainable marine fisheries management practices as an effort to maintain fish resource resilience by integrating ecological, economic, and social dimensions. The research employed a descriptive-analytical approach based on secondary data obtained from national fisheries statistics, scientific journals, and international reports published between 2015 and 2025. Data were analyzed using a qualitative synthesis method supported by sustainability indicators, including stock status, fishing effort, governance effectiveness, and community participation. The results indicate that sustainable fisheries management, particularly ecosystem-based fisheries management, rights-based fisheries, and the implementation of blue economy principles, significantly contributes to maintaining fish stock resilience. However, governance gaps, weak enforcement, and limited stakeholder integration remain major constraints. This study concludes that strengthening institutional capacity, improving data quality, and enhancing community-based management are essential to achieving long-term sustainability of marine fisheries resources. The findings provide practical and theoretical contributions to fisheries management policy development in Indonesia and other developing maritime countries.

Abstract

Marine fisheries face increasing pressure from overexploitation, climate variability, and ecosystem degradation. Conventional single-species management approaches have proven insufficient to address these complex challenges. Ecosystem-Based Fisheries Management (EBFM) has emerged as an integrated framework that considers ecological, environmental, economic, and social dimensions of fisheries systems. This study aims to develop a conceptual model of ecosystem-based marine fisheries management to support long-term resource sustainability. The study applied a qualitative systematic review combined with comparative analysis of empirical EBFM case studies from tropical and temperate marine ecosystems. Data were collected from peer-reviewed international and national journals published between 2008 and 2025. The analysis focused on ecosystem indicators, management domains, governance mechanisms, and adaptive strategies. The results show that effective EBFM models consistently integrate habitat protection, biodiversity monitoring, stakeholder participation, and climate-responsive management tools. Tropical fisheries require stronger emphasis on spatial planning and community-based governance due to high ecological sensitivity and socio-economic dependence. The proposed model synthesizes ecological thresholds, adaptive management cycles, and participatory decision-making processes. This model provides a practical framework for policymakers and fisheries managers to enhance resilience and sustainability of marine fisheries systems. The study contributes to the operationalization of EBFM in developing country contexts.

Abstract

Sustainable marine fisheries play a critical role in ensuring global food security while simultaneously supporting the economic development of coastal communities. Overexploitation of marine resources, climate change, and ineffective governance have posed significant threats to fisheries sustainability, particularly in developing coastal regions. This study aims to examine the contribution of sustainable marine fisheries to food security and coastal economic development through a systematic literature-based and empirical assessment approach. A mixed-methods design was applied, combining secondary data analysis from international organizations and peer-reviewed journals with qualitative insights from coastal fisheries management practices. The findings indicate that sustainably managed marine fisheries significantly enhance protein availability, stabilize livelihoods, and promote inclusive economic growth in coastal areas. Furthermore, fisheries governance frameworks that integrate ecosystem-based management and social equity principles demonstrate higher resilience against environmental and economic shocks. The study concludes that sustainable marine fisheries are not only a food production system but also a strategic economic pillar for coastal development. Strengthening policy coherence, community participation, and adaptive management is essential to maximize the long-term contribution of marine fisheries to food security and coastal economies.
