Natural Dynamics

Human population density is globally three times higher along the coasts than inland, and thus environmental impacts of human activities are greater in magnitude on coastal ecosystems such as beaches and dunes. Vulnerability assessment (the loss of capacity to return to the original dynamic state after system displacement) is thus necessary to evaluate the conservation status and determine the most relevant disturbance events. Twenty-six sites along 902 km of Gulf of Mexico coastline, varying in conservation status and sedimentary dynamics, were sampled. At each site a vulnerability index (VI) was calculated based on variables that described geomorphological condition, marine influence, aeolian influence, vegetation condition and human effects. Vulnerability was very variable along the coast and only 19% of the sampled locations (mostly in the central Gulf of Mexico) displayed low vulnerability. Cluster analyses of the values assigned to the checklists for each location grouped the studied sites into three, according to their VI values. Low vulnerability locations had abundant sediment supply and low human impact. Locations with medium to high VI were mostly affected by their natural geomorphological and marine features and had medium to intense human activities. Management strategies should consider the observed variability in vulnerability, the natural dynamics of these systems and the role of human activities and interests, in order to achieve adequate policies and establish well-informed priorities for integrated coastal zone management.

Gulf Of Cádiz

Numerous human activities take place in the marine area of ​​the Gulf of Cádiz, making it necessary to organize space through their spatial and temporal distribution. With the aim of combining the long-term conservation of marine biodiversity and the development of an economic activity that makes it possible to maintain over time the capacity of the marine environment to provide ecosystem services. Marine Spatial Planning (MSP) is being an effective process regarding the spatial and temporal distribution of human activities in the marine space to the achievement of ecological, economical and social objectives. MSP is usually schematized in 10 phases, in which among others it is found 5th phase: Defining and analyzing existing conditions. The aim of this document is the development of this phase in the Gulf of Cadiz, pretending to provide some of the needed basis to cope effectively with this process. Furthemore, in order to transfer the analyzes to the territory, Geographic Information Systems (GIS) have been used, showing how useful these are to address PEM processes. It is worth highlighting, among the results, the need to develop the MSP within a framework of cooperation and coordination between the Administrations that undertake the planning and Integrated Coastal Zone Management (ICZM), that is, MSP and ICZM. In the Gulf of Cadiz, the main conflictive areas have been detected near to the coast and in semi-closed environments, such as bays and estuaries.

Abstract. Wind, waves, tides, sediment supply, changes in relative sea level and human activities strongly affect shorelines, which constantly move in response to these processes, over a variety of time scales. Thus, the implementation of sound coastal zone management strategies needs reliable information on erosion and/or deposition processes. Suggesting a feasible way to provide such information is the main motivation of the present work. A chain approach is here proposed, tested on a vulnerable coastal site located along the southern Italy, and based on the joint analysis of field data, statistical tools and numerical modelling. Firstly, the coastline morphology has been examined through interannual field data, such as aerial photographs, plane-bathymetric surveys, seabed characterization. After this, rates of shoreline changes have been quantified with a specific GIS tool. Correlations among the historical shoreline positions have been detected by statistical analysis and have been satisfactorily confirmed by numerical modelling, in terms of recurrent erosion/accretion area and beach rotation trends. Finally, based on field topographic, sediment, wave and wind data, the response of the beach by the numerical simulation has been investigated in a forecasting perspective. The scope of this study is providing a feasible, general and replicable chain approach, which could help to thoroughly understand the dynamics of a coastal system, identifying typical and recurrent erosion/accretion processes, and predict possible future trends, useful for planning coastal activities.

Data Layers

Multiple funding mechanisms support restoration across the northern Gulf of Mexico. To maximize environmental, societal, and financial benefits of these investments, best use of available science is needed to inform project prioritization and planning processes. Synthesizing available data across the northern Gulf of Mexico can provide information on potential threats to, and benefits from, projects or suites of projects. To achieve this, subject matter experts from Alabama, Florida, Louisiana, Mississippi and Texas were identified with recommendations from each of the RESTORE Act Centers of Excellence. These experts provided known sources of Gulf-wide data and recommended metrics that would be most informative, resulting in 40 threat, 19 habitat and 10 community primary data layers. Two tessellated geospatial hexagon grids were generated to provide uniform coverage that encompassed a 25-mile buffer of the Coastal Zone Management Act (CZMA) boundary at a spatial grid resolution of 100 km2 and 1 km2. The two resultant grid domains included all counties in the five Gulf states determined by the National Oceanic and Atmospheric Administration (NOAA) as contributing to coastal watersheds. The varying grid resolutions allowed for data to be spatially visualized both at a broad Gulf-wide scale on the 100 km2 grid as well as at a regional and project level scale on the 1 km2 grid. The data layers were synthesized into combined layers of potential stress, potential ecological benefits, and potential community benefits. These layers support broad scale prioritization for restoration efforts, based on likelihood of success and desired outcomes. The synthesized data were discussed in the context of the five goals and four priority criteria of the Gulf Coast Ecosystem Restoration Council’s (RESTORE Council) aim of using best available science (BAS) to guide future funding for restoration at large and small scales.

Management Protocol

SUMMARYThe Integrated Coastal Zone Management protocol of the Barcelona Convention sets governance objectives for countries bordering the Mediterranean Sea. This protocol emphasizes collaborative approaches to acknowledge the role of local people in coastal management. Evaluating the quality of governance processes is critical if coastal zone values are to be effectively managed in times of global climate change. This study examined the structure and attributes of collaborative governance networks in two Mediterranean deltas, the Camargue (France) and Gediz Delta (Turkey). A deliberative social catchment sampling was used to target actors with physical, cultural, social or economic ties. Forty-five different organizations/professions were interviewed using a standardized questionnaire to identify the frequency and quality of contacts, information flows, and subject matter relevant to natural resource management. There were higher levels of degree centrality and reciprocal ties in the Camargue, while the Gediz Delta had a greater homogeneity of actors, with one centralized influential actor. Civil society played a greater role in the Camargue network, and government organizations were more central in the Gediz Delta. The differences between the two sites call into question the use of the same integrated management strategies and suggest the need to acknowledge the importance of existing governance models and relationships within local contexts.

Severe Erosion

We analyze decision making under uncertainty in a search for an integral management solution for Playa Granada in the Guadalfeo River Delta (Granada, Spain), where the construction of a dam in the river basin is causing severe erosion. Different management strategies are considered. For each of them the assessment of the uncertainty in the accomplishment of the management targets is done with a methodology that takes into account the coupled action of atmosphere, ocean, and land agents and their intrinsic stochastic character. This information is used to infer the joint distribution function of three criteria that represent the economic benefit of different interest groups. A stochastic multicriteria decision method that accounts for the uncertainty in the performances of alternatives and also in decision makers preferences, is used to rank strategies according to their effectiveness in an informed and transparent process.

The Impact

Coastal ecosystems undergoing rapid urbanisation have characteristics of both natural and artificial ecosystems. How we evaluate the dynamic impact of human activities on coastal ecosystems is important for coastal zone management and development. In this study, we first developed a method to extract both the natural and artificial features of coastal land cover, and classified the coastal landscapes impacted by human activities from an ecological service perspective. We then constructed an ecological interference index for classification to evaluate the impact of coastal human interference on both artificial and natural ecosystems during rapid urbanisation. Lastly, we verified our method by applying it to the coastal zone in Shenzhen, China. Our results show that this method can describe the effects of human activities on coastal zones in more detail. The distribution of human activity was mainly associated with the geomorphology of the coastal zone. Changes in human interference were seen strongly in proximity to both the landward and coastal boundaries of the study area, in close correlation with the public’s increasing conscience for ecological environment protection.

The aims of this study are to analyze the role, interest, and influence of stakeholders in the coastal zone management of Gunungkidul, as well as to formulate sustainable coastal management strategies. The research used quantitative and qualitative methods with questionnaires and in-depth interview. Data were collected from April to July 2018; processed by Mactor software and analysed using stakeholder analysis. The results showed that coastal management of Gunungkidul Regency involved three key stakeholders, six primary stakeholders, and three supporting stakeholders as a coordinator, facilitator, and implementer. Mapping stakeholders shows the categories of stakeholders involved in the management of coastal zones as subjects, players, actors, and spectator. Therefore, strategies are necessary to optimize stakeholder arrangements in realizing sustainable coastal area management through increasing collaboration and cooperation between subjects and players who have a level high of power and interest in coastal management policies. The sustainable coastal area management policies can be realized through effective collaboration and cooperation between government and community. The strategies must also involve all related parties to protect natural resources and environment, to concern with environment quality, and it increase the income of coastal communities.
