KONDISI SOSIAL BUDAYA DAN EKONOMI MASYARAKAT YANG MEMANFAATKAN KAWASAN EKOSISTEM MANGROVE DI KAMPUNG BUKISI KABUPATEN JAYAPURA

Background : Mangroves are plants whose natural habitat is in coastal areas, so they absolutely need the role of coastal communities, who need empowerment in the implementation of mangrove management. Therefore, the sustainability of coastal areas will be maintained because of conservation activities, as well as they can obtain socio-economic benefits. Along with the increase in population and the high needs of the community, the high level of utilization of mangrove resources has resulted in a high level of utilization of mangrove resources. On the other hand, damaged natural resources, because they are not taken care of by the surrounding community, and are not taken care of by the surrounding community, can hardly meet the needs of the community in Bukisi Village. The purpose of the research is to examine the social, cultural and economic conditions of the people living around the mangrove ecosystem area in Bukisi Village, Yokari District, Jayapura Regency. Method: The research methods used were qualitative and quantitative descriptive methods as well as an overview of social, cultural and economic conditions in the utilization of mangrove ecosystems in Bukisi Village and 35 communities who were used as respondents. Results: Respondents were dominated by men, productive age 26-35 years, predominantly elementary school educated, fishermen, with an income of IDR 1,500,000 - IDR 2,500,000. Socio-economic characteristics illustrate that respondents who utilize the mangrove ecosystem are residents who live around the area and there are sacred places around the mangrove ecosystem area, so that no one is allowed to carry out activities in sacred locations. People in Bukisi village often use the mangrove ecosystem area to look for fish, shellfish, shrimp, crabs and even for firewood. Conclusion: Sustainability management strategies that are prioritized in terms of social, cultural and economic conditions as well as the role of stakeholders who are the most important actors in mangrove forest management in Bukisi Village, Yokari District, Jayapura Regency.

Numerical study of wave run-up on sea dikes with vegetated foreshores

Integrating coastal vegetation into sea dikes is a nature-based approach aimed at combining disaster prevention with ecological sustainability in coastal areas. This study investigates the impact of vegetation on the wave run-up on dikes through numerical analysis. The numerical model used in the study solves the Reynolds-averaged Navier–Stokes equations by adding a vegetation resistance force to account for momentum loss. A stabilized k–ω shear stress transport model considering the vegetation effect was adopted for turbulence closure. A series of numerical simulations was carried out on the wave run-up (Ru) on dikes, focusing on the effects of different vegetation heights, densities, zone lengths, and dike slopes under various wave conditions. The results indicate that vegetation can significantly decrease Ru and may cause the wave to change from breaking to nonbreaking on dikes. The Ru behaviors depend on whether waves break and can be well characterized by the Iribarren number and dimensionless wave momentum flux parameter under breaking and nonbreaking conditions, respectively. Finally, the multivariate non-linear regression (MNLR) and artificial neural network (ANN) methods were adopted to explore a prediction model for evaluating Ru. Comparisons showed that the prediction performance of the ANN model is superior to that of the MNLR model. The ANN model has the potential as a promising predictive tool for obtaining wave run-up on dikes with vegetated foreshores under breaking and nonbreaking conditions.

Reconfiguration of Coastal Settlement Policy in Blue Economy Paradigm: Discources and Practices in Bintan Island, Indonesia

The blue economy paradigm promotes sustainable economic growth by linking social equality, poverty reduction and marine conservation. Bintan Island, a designated Special Economic Zone (SEZ), has faced a challenge in accommodating economic growth and social equality for indigenous people living in coastal settlements. Providing settlement permits and recognition of property rights must consider the sustainability of coastal areas and spatial allocations along the coast of Bintan Island. Policy changes and policy networks in implementing coastal settlement policy become the theoretical framework in this study. Drawing on discourse analysis, key-informant interviews across scales, and secondary data in the regulations, we examine the meanings and practices of the reconfiguration of Coastal Settlement Policy in Blue Economy Paradigm. Policy networks perform in implementing coastal settlement policy to provide legalisation of assets as a form of social equity in the blue economy paradigm. The initiative of the regional head also followed the establishment of Bintan as an SEZ by strengthening the coastal settlement certification programme. However, within the framework of the policy network, the intergovernmental relationship that works in this policy needs strengthening from other networks.

The Effects of Climate Change on Coastal Areas and Coastal Property and Floating Cities As a Solution Proposal

This research examines the impacts of climate change on water levels in coastal areas and focuses on strategies to cope with these impacts. Research shows that climate change will have negative impacts such as rising sea levels, flooding, loss of settlements and forced migration. This necessitates the development of climate change compatible policies in coastal areas. The paper addresses sustainable and resilient urban planning strategies in this context. It also evaluates floating city projects that stand out as an effective solution against future water level rises. Floating cities offer innovative concepts that can adapt to rising water levels, are eco-friendly, self-powered and offer sustainable living spaces. The research examines the potential advantages of these projects for addressing property issues and environmental sustainability in coastal areas, while emphasizing that these projects could be an important alternative for future coastal areas. As a result, it emphasizes the role of floating city projects in the development of effective and sustainable strategies to combat climate change and sheds light on future research in this field and its applicability in Turkey.

How Eco-Spatial Edutourism Support Sustainability in Coastal Areas in South Malang, Indonesia?

This study aimed to determine the effect of edutourism based on eco-spatial to support sustainability in coastal areas in South Malang, East Java, Indonesia. The qualitative research design is conducted at Kondang Merak Beach, Pesanggrahan Beach, Bajulmati Beach, CMC (Clungup Mangrove Conservation) Tiga Warna, Tamban Beach, and Perawan Beach, which located in South Malang Regency, East Java, Indonesia. Data were taken using participant observation, documentation, and in-depth interviews. Data analysis used qualitative analysis from Miles and Huberman, consisting of three stages, reduction, data presentation, and conclusions. The result found that each beach has unique qualities depending on the surrounding environment and can be developed into an edutourism destination. Edutourism has benefited environmental sustainability, showed in the condition of natural resources in maintained tourist attractions (mangroves, coral reefs, pine shrimp, sea pandanus, turtles, and crabs), and maintained cleanliness at tourist areas.

Evaluation and Correlation Analysis of Surface Water In and Around Mangalore Coastal Belt, Karnataka, India

Urbanisation, industrialisation, population growth and various agricultural activities in and around coastal areas have led to a significant amount of pollutants into the surrounding aquatic ecosystem such as estuary, river, sea, seashore and coastal wetlands. This causes ecological degradation. Pollution is one of the major challenges to the sustainability of coastal areas. In the study area, major industries are located on the Gurupur river bank which joins the Nethravati river to form a common estuary before entering the Arabian sea. The major activities that are responsible for coastal pollution in the study area are discharge and disposal of untreated domestic and industrial wastes to estuaries, rivers, nearshore waters and harbour activities. Gurupura and Nethravthi are two west flowing rivers of the Mangaluru coastal region. They receive a large amount of pollution load from the nearby industries causing the deterioration of the water quality. In this study, 10 surface water samples which include stream water, river water and sea water, were collected during the pre-monsoon and post-monsoon and analysed for various water quality parameters by adopting standard methods. The study reveals that the electrical conductivity, total dissolved solids and chlorides concentration of most of the surface water samples were met above the standard limits in both seasons. From the correlation analysis, it was found that a very strong correlation was observed between chlorides and hardness (0.9691), TDS and conductivity (0.9227) during post-monsoon season of 2018 and TDS and conductivity (1.00), COD and chlorides (0.8922), DO and chlorides (0.8810) during pre-monsoon of 2019.

Intervention Strategy for Ecosystem-Based Tourism Sustainability in Coastal Areas and Gili Matra Small Islands

The development of coastal ecosystem-based tourism in Gili Matra has been very massive and tends to exceed capacity. For this reason, it is necessary to review the existing ecosystem status in mapping out appropriate intervention strategies in tourist areas. The research during 2021 at 13 locations in Gili Matra aims to look at the pattern and status of the ecosystem for the preparation of tourism development intervention strategies. Data analysis includes descriptive and cluster analysis of the pattern of ecosystem structure, habitat, and resources. The results showed that 30.7% of hard coral cover was still in good condition, and 69.23% was in poor condition. The coral health index level is also with the same percentage value as coral cover. Meanwhile, fish species richness that exceeds 5 species reaches 61.53% and less than 5 species by 38.46%. The general conclusion is that coral reefs are under pressure, although fish biodiversity is still high. The intervention strategy is through efforts to increase coral coverage, and while fishing tourism activities must be managed properly, so as not to damage coral reefs and maintain the target fish population.

Study on Spatiotemporal Evolution of the Yellow River Delta Coastline from 1976 to 2020

The Yellow River Delta in China is the most active one for sea–land changes over all deltas worldwide, and its coastline evolution is critical to urban planning and environmental sustainability in coastal areas. Existing studies rarely used yearly temporal resolution, and lack more detailed and quantitative analysis of coastline evolution characteristics. This paper used visual interpretation to extract the coastline of the Yellow River Delta in year interval Landsat images for 45 years from 1976 to 2020, and analyzed the spatiotemporal characteristics of the coastline evolution through statistical methods such as calculating change values and change rate. The main results are as follows: (1) overall, the coastline of the Yellow River Delta presented a spatial pattern involving northern landward retreat and southern seaward expansion. Since 1990, the Yellow River Delta has entered a period of decline. In addition, the length of the artificial coastline increased by about 55 km; (2) in the Qingshuigou region, the land area and the coastline length increased first and then stabilized. The southeastern part of the Qingshuigou was in a state of erosion, while the northeastern part was expanding toward the sea along the north direction; (3) in the Diaokou region, the land area has been decreasing, but the reduction rate has gradually slowed down. The main conclusions are as follows: (1) through the research on the evolution model and mechanism of the coastline of the Yellow River Delta, it was found that human factors and natural factors were the two major driving factors that affect the evolution of the coastline; (2) a river branch appeared in the northern part of the Qingshuigou region in 2014 and became a major branch in 2020, which would affect the development of the coastal region of Chengdao. This study is important for better understanding the evolution pattern of the Yellow River Delta coastline and will help to provide guidance for coastline management and resource exploitation.

Low-Cost Archaeological Investigation and Rapid Mapping of Ancient Stone Tidal Weirs in the Penghu Archipelago Using Google Earth

This paper provides a brief history review of the use of ancient weirs in fishing on our planet, as well as a pilot study that involves investigating and mapping the coastal heritage of ancient stone tidal weirs (STWs) in the Penghu Archipelago which is located in the Taiwan Strait. The spatial distribution and morphological features of STWs across Penghu Archipelago were investigated and analyzed using very high-resolution (VHR) and freely available Google Earth (GE) imagery and geographic information system (GIS) analysis tools. A total of 539 ground-truthed STWs were identified from multiple temporal GE images, and these accounted for over 90% of the localized inventory databases. The proposed GE-based method was found to be more efficient, timely and effective compared to field and airborne surveys. This paper illustrates the utility of GE as a source of freely available VHR remote sensing imagery for archaeological surveys and heritage sustainability in coastal areas.

Strong sustainability in coastal areas: a conceptual interpretation of SDG 14

Humans derive many tangible and intangible benefits from coastal areas, providing essential components for social and economic development especially of less developed coastal states and island states. At the same time, growing human and environmental pressures in coastal areas have significant impacts on coastal systems, requiring urgent attention in many coastal areas globally. Sustainable development goal (SDG) 14 of the 2030 Agenda for Sustainable Development (henceforth the 2030 Agenda) aims for conservation and sustainable use of the oceans, seas, and marine resources, explicitly considering coastal areas in two of its targets (14.2 and 14.5). These promote, as we argue in this article, a strong sustainability concept by addressing protection, conservation, and management of coastal ecosystems and resources. The 2030 Agenda adopts the so-called “three-pillar-model” but does not specify how to balance the economic, social, and environmental dimensions in cases of trade-offs or conflicts. By analysing SDG 14 for the underlying sustainability concept, we derive decisive arguments for a strong sustainability concept and for the integration of constraint functions to avoid depletion of natural capital of coastal areas beyond safe minimum standards. In potential negotiations, targets 14.2 and 14.5 ought to serve as constraints to such depletion. However, such a rule-based framework has challenges and pitfalls which need to be addressed in the implementation and policy process. We discuss these for coastal areas in the context of SDG 14 and provide recommendations for coastal governance and for the process ahead.

Second homes, legal framework and planning practice according to environmental sustainability in coastal areas: the Swedish setting

The aim of this article is to discuss second homes according to legislation, planning practice and effects on environmental sustainability in a Swedish context. The legislation contains special provisions concerning land and water management in certain areas of national interest in their entirety in view of the natural and cultural assets that exist there. Subject to resource conservation regulations, new vacation housing will be limited to infill, with no new land development. There is no such restriction for permanent housing. Spatial theory according to Lefebvre is used to discuss ideas in legislation and spatial planning versus actual development of vacation housing in coastal areas over time. Documents have been analyzed from a discourse analytic perspective inspired by Laclau and Mouffe. The legal ambition to separate dwelling forms seems to be unstable and ambiguous. An alternative pragmatic attitude within planning practice has developed and seems to increase according to the study.

Beach Carrying Capacity Analysis for Sustainable Tourism Development in the South West Coast of India

The rapid growth of coastal tourism that has been seen in the last 10 years is frequently described as one of the major reasons for the development of these areas and also is responsible for many current coastal problems. The beaches perform, in this context, a fundamental role, where the issues related to planning and management are increasingly more important when it comes to an implementation of a sustainable development philosophy. In Kerala, where coastal tourism plays a major part of the state’s economy, the management of beaches is crucial for maintaining their quality and therefore continuing to attract tourists. Since the 1990s, with the application of Coastal Zone Management Plans to the whole Kerala coast, beach plans are now required. The concept of capacity has received considerable attention as a result of increasing anthropogenic pressure in certain natural environments. Much consideration has recently been given to an increase in coastal population, with the implication that the carrying capacity of the world’s coast is finite, and such consideration forms part of several coastal management initiatives. Tourism is the world’s largest industry, which accounts for more than 10% of total employment, 11% of global GDP, and total tourist trips are predicted to increase to 1.6 billion by 2020. The ecosystems, typically stressed by development activity along the Indian coastal areas, are particularly vulnerable to socio-economic driving forces. The planning and management of coastal tourism can be improved through more careful understanding of social and ecological systems and their linkages, with a view to ensure a development that lasts, not only for tourism but also for the host destination. The present study gives a comprehensive idea on both sustainability of coastal areas and a prerequisite for the carrying capacity based development in tourism destinations.DOI: http://dx.doi.org/10.5755/j01.erem.63.1.2648

Tourism Activities and its Impact on Environmental Sustainability in Coastal Areas

Tourism Activities and its Impact on Environmental Sustainability in Coastal Areas

In search of coastal zone sustainability by means of social carrying capacity indicators construction: lessons learned from the Thau lagoon case study (Region Languedoc-Roussillon, France)

This paper aims at shedding new light on sustainability in coastal areas while defining a methodology for constructing social carrying capacity indicators. These indicators evaluate the levels and thresholds related to population growth pressures. From a Driver-Pressure-State-Impact-Response (DPSIR) framework, we centre on the Pressure and State processes and we follow a Principles-Criteria-Indicators (PCI) outline to distinguish the underlying pressures on the coastal zone. The main assumption of this article is that social carrying capacity within the coastal zone needs a multidimensional study by means of a set of indicators. We consider that social carrying capacity indicators provide standards for sustainability, and we identify sustainable and critical levels of pressures. How coastal practitioners and municipal councillors perceive the various challenges and how they use the indicators are assessed. The results show various degrees of involvement and scale misunderstandings on the part of policy makers.

The use of DPSIR framework to evaluate sustainability in coastal areas. Case study: Guanabara Bay basin, Rio de Janeiro, Brazil

The Guanabara Bay basin, SE Brazil, is shown as an experimental site to evaluate development and sustainability in coastal areas. We developed a Driver–Pressure–State–Impact–Response (DPSIR) framework in a practical context to integrate natural and socio-economic indicators. Sustainability reflects public policies towards the utilization of natural resources. Cost-benefit analysis (CBA) included in DPSIR evaluates losses and benefits resulting from such policies. CBA has some limitations due to the difficulty of valuating environmental goods and services. Instead of valuating them we propose to combine sustainability indicators and defensive expenditures for the implementation of public policies. This approach agrees with the environmental conservation paradigm implicit in sustainable development. It allows an estimation of the physical natural capital depreciation (PNCD), by using it to correct the gross domestic product (GDP) of the study area, and demonstrating the present non-sustainable characteristics of the current policies applied to the area.
