In partnership with the U.S. Geological Survey Coastal and Marine Hazards and Resources Program (USGS CMHRP) and the U.S. Coastal Research Program (USCRP), the American Shore and Beach Preservation Association (ASBPA) has identified coastal stakeholders’ top coastal management challenges. Informed by two annual surveys, a multiple-choice online poll was conducted in 2019 to evaluate stakeholders’ most pressing problems and needs, including those they felt most ill-equipped to deal with in their day-to-day duties and which tools they most need to address these challenges. The survey also explored where users find technical information and what is missing. From these results, USGS CMHRP, USCRP, ASBPA, and other partners aim to identify research needs that will inform appropriate investments in useful science, tools, and resources to address today’s most pressing coastal challenges. The 15-question survey yielded 134 complete responses with an 80% completion rate from coastal stakeholders such as local community representatives and their industry consultants, state and federal agency representatives, and academics. Respondents from the East, Gulf, West, and Great Lakes coasts, as well as Alaska and Hawaii, were represented. Overall, the prioritized coastal management challenges identified by the survey were: Deteriorating ecosystems leading to reduced (environmental, recreational, economic, storm buffer) functionality, Increasing storminess due to climate change (i.e. more frequent and intense impacts), Coastal flooding, both Sea level rise and associated flooding (e.g. nuisance flooding, king tides), and Combined effects of rainfall and surge on urban flooding (i.e. episodic, short-term), Chronic beach erosion (i.e. high/increasing long-term erosion rates), and Coastal water quality, including harmful algal blooms (e.g. red tide, sargassum). A careful, systematic, and interdisciplinary approach should direct efforts to identify specific research needed to tackle these challenges. A notable shift in priorities from erosion to water-related challenges was recorded from respondents with organizations initially formed for beachfront management. In addition, affiliation-specific and regional responses varied, such as Floridians concern more with harmful algal blooms than any other human and ecosystem health related challenge. The most common need for additional coastal management tools and strategies related to adaptive coastal management to maintain community resilience and continuous storm barriers (dunes, structures), as the top long-term and extreme event needs, respectively. In response to questions about missing information that agencies can provide, respondents frequently mentioned up-to-date data on coastal systems and solutions to challenges as more important than additional tools.

A governança ambiental no Brasil tem avançado significativamente nas últimas décadas, principalmente no que concernem as políticas públicas. No contexto da descentralização do poder institucional, o município vem adquirindo papel de relevância como entidade executora das ações orientadas pela governança. No âmbito da gestão costeira, hoje há diversos meios legais que reafirmam a importância do gerenciamento do litoral em áreas densamente urbanizadas, nesse quesito, todos os níveis detêm diversos mecanismos que podem auxiliar significativamente para a gestão adequada das áreas litorais. Dessa forma, a partir das diretrizes da governança ambiental brasileira, o presente artigo tem por objetivo analisar a gestão costeira dos municípios litorâneos cearenses a partir da atuação das secretarias municipais de meio ambiente dos referentes municípios. Sendo assim, foi aplicado um questionário eletrônico direcionado aos gestores públicos de órgãos e/ou secretarias de meio ambiente. Em que foram analisados aspectos da sua estrutura técnica de implementação das políticas públicas de gestão costeira, bem como as respostas municipais de gestão com base local. Levou-se em consideração para esta análise apenas os municípios que possuem orla marítima.  Com base na estrutura que orienta a boa gestão, aqui entendida como Governança, foi possível identificar a capacidade técnica de resposta dos órgãos de meio ambiente dos municípios costeiros cearenses frente as problemáticas de gestão de suas orlas.  E sobre todas essas questões, a governança assume o papel direcionador de boas práticas para melhorar a gestão costeira.Palavras-chave: Governança.

In the context of the decentralization of institutional power, the municipality has been acquiring a relevant role as an executing entity of governance-oriented actions. In the context of coastal management, today there are several legal means that reaffirm the importance of coastal management in densely urbanized areas. In this regard, all levels have several mechanisms that can significantly assist in the proper management of coastal areas. Thus, based on the guidelines of the Brazilian environmental governance, this article aims to analyze the coastal management of the coastal municipalities of Ceará from the performance of the municipal environmental secretariats of the referred municipalities. Thus, an electronic questionnaire was applied to public managers of environmental agencies and / or departments. In which aspects of its technical structure for the implementation of coastal management public policies were analyzed, as well as the municipal based management responses. For this analysis, only the municipalities with seafronts were considered. Based on the structure that guides good management, understood here as Governance, it was possible to identify the technical capacity of the environmental agencies of Ceará coastal municipalities to respond to the problems of managing their borders. And on all these issues, governance assumes the guiding role of good practice for improving coastal management.Keywords: Governance. Coastal Management.

The volume of material required for the construction of new and expansion of existing beach sites is an important parameter for coastal management. This information may play a crucial role when deciding which beach sites to develop. This work examines whether artificial neural networks (ANNs) can predict the spatial variability of nourishment requirements on the Croatian coast. We use survey data of the nourishment volume requirements and gravel diameter from 2016 to 2020, fetch length, beach area and orientation derived from national maps which vary from location to location due to a complex coastal configuration on the East Adriatic coast, and wind, tide, and rainfall data from nearby meteorological/oceanographic stations to train and test ANNs. The results reported here confirm that an ANN can adequately predict the spatial variability of observed nourishment volumes (R and MSE for the test set equal 0.87 and 2.24 × 104, respectively). The contributions of different parameters to the ANN’s predictive ability were examined. Apart from the most obvious parameters like the beach length and the beach areas, the fetch length proved to be the most important input contribution to ANN’s predictive ability, followed by the beach orientation. Fetch length and beach orientation are parameters governing the wind wave height and direction and hence are proxies for forcing.

Bathtub Model

Sea-level rise is a problem increasingly affecting coastal areas worldwide. The existence of free and open-source models to estimate the sea-level impact can contribute to improve coastal management. This study aims to develop and validate two different models to predict the sea-level rise impact supported by Google Earth Engine (GEE)—a cloud-based platform for planetary-scale environmental data analysis. The first model is a Bathtub Model based on the uncertainty of projections of the sea-level rise impact module of TerrSet—Geospatial Monitoring and Modeling System software. The validation process performed in the Rio Grande do Sul coastal plain (S Brazil) resulted in correlations from 0.75 to 1.00. The second model uses the Bruun rule formula implemented in GEE and can determine the coastline retreat of a profile by creatting a simple vector line from topo-bathymetric data. The model shows a very high correlation (0.97) with a classical Bruun rule study performed in the Aveiro coast (NW Portugal). Therefore, the achieved results disclose that the GEE platform is suitable to perform these analysis. The models developed have been openly shared, enabling the continuous improvement of the code by the scientific community.

Critical Understanding

AbstractIntegrated coastal management (ICM) programmes are being planned, formulated and implemented in coastal States all over the world. To date, however, ICM has been seen as more in the realm of policy-makers, managers, scientists, coastal resource economists, and others, rather than in the realm of lawyers. This article reveals how law and lawyers should play an absolutely essential role at all stages of the ICM process. Ideally, ICM legal consultants will have a broad range of knowledge and experience in both international legal treaties as well as in certain fundamental national law principles, so that coastal zone policies will be designed and carried out with a critical understanding of the laws and institutions needed for the long-term success of an integrated coastal management programme.
