ASBTRACT Some sectors of the west Portuguese coast are particularly endangered by erosion and flooding. Regional to local scale information, on coastline evolutionary trend, is particularly valuable in sectors that includes areas with relevant erosion. A continuous, high-resolution, dataset on coastal evolution, from 1947 and 2015, between Figueira da Foz and Nazaré, was achieved within the Programme “Geological and Coastal Hazard Mapping at a 1:3000 resolution scale” at the National Laboratory of Energy and Geology (LNEG). This work, due to the detailed scale of analysis in a wide geographic context, allows to have both, a general overview of the coastal evolution and, at the same time, when zooming in up to 1:3000 scale, to observe the local behaviour and to quantify the occurred changes. Also, the well time-spaced aerial photograph dataset allows to compare the resultant coastline movement between the oldest and the youngest coastline (NSM index), with the total coastline oscillation (SCE index), bringing new insights on the coastline stability at a local scale. The evolution trend shows an overall erosional behaviour, if considering the entire sector. Erosion occurs predominantly in the north, as the south shows more stability and progradation. Quantification of the land-lost and land-gain due to the coastline shift in a 68-year period shows that 1 164 888 m2 of land were lost along 30 470 m of the coastal fringe, and 462 330 m2 were gained along an extension of 21 010 m.

RESUMO A implementação de mecanismos de gestão de Unidades de Conservação (UCs) e de áreas costeiras, de maneira integrada, são fundamentais nos processos de previsão de impactos e desastres, e na criação de medidas de mitigação. As zonas costeiras estão sujeitas a uma vulnerabilidade ambiental quanto a mudanças climáticas, pressões antrópicas e acidentes químicos em diferentes escalas. Dessa forma, o presente trabalho tem como objetivo analisar os planos de manejo das UCs Marinhas atingidas pelo derramamento de óleo na zona costeira do Brasil no ano de 2019, tendo em vista a verificação e análise da presença de planos de contingenciamento, bem como a identificação de possíveis ações propostas para mitigação do referido impacto. Com esta pesquisa, pôde-se constatar que das 119 UCs Marinhas nos estados atingidos, apenas 42 apresentaram plano de manejo. Destas, 20 faziam parte da área atingida pelos derramamentos, abrangendo 26 municípios em 7 estados, porém, nenhuma delas apresentou em seu plano de manejo ações referentes ao contingenciamento ou mitigação de impactos devidos a acidentes químicos. Ademais, em relação a atualização dos planos de manejo, os mesmos encontraram-se desatualizados desde a sua publicação nos anos 90, como verificado nas Unidades do estado da Bahia. Sendo assim, sugere-se que ao realizar as atualizações, os planos venham a incluir especificações direcionadas a incidentes com químicos, em especial o petróleo, além das demais ações antrópicas as quais os ambientes costeiros estão predispostos.

ABSTRACT Brazil has great potential for the development of technologies for the conversion of marine energy from waves and tides, which raises the discussion about the possible environmental impacts of these projects. This article seeks to synthesize knowledge about the risks of collision of marine animals, such as mammals, fish and birds, with marine renewable energy (MRE) devices, as well as to identify priority species for environmental monitoring along the Brazilian coast. The risk of marine mammals colliding with MRE devices is influenced by regional and behavioral factors. The risk of collision in a fish community is influenced by the avoidance behavior, the distribution of fish in the MRE sites and the stages of the enterprise (installation, operation and maintenance). Seabird collision risk is influenced by species behavior (geographical distribution, seasonal habitat use, diving time and depth) and the location of MRE structures (surface and/or water column). The survey of priority species for monitoring the risk of collision with MRE devices in Brazil consisted of 5 species of marine mammals, 13 taxa of seabirds, 5 species of endangered sea turtles and 18 species or groups of species of fish of economic importance to the country. The research review did not record the occurrence of collisions with marine animals. However, this does not mean that they did not occur, but that they may not have been observed due to monitoring challenges. The study concluded that research on the interaction of marine animals with MRE devices should be encouraged, even in prototypes and non-commercial projects, in order to reduce knowledge gaps and support the development of MRE in an environmentally sound manner. Keywords: Marine renewable energy, Collision risk, Species, Marine animals.

Coastal regions show a varied exposure to anthropogenic and natural risks, whose impact can often endanger the delicate balance of coastal habitats. Over the past issues of the Journal of Integrated Coastal Zone Management, several coastal risks have been broadly analysed, along with practical case studies, novel research and scientific findings ( e.g ., Taveira-Pinto et al . (2021), Hoff et al . (2022) and Costa (2022)). The continuous study of coastal risks, hazards, and the short or long-term interactions between inhabitants and the coast, remains an important research topic, particularly given the rising pressure in coastal areas, due to widely known factors, e.g . climate change, increasing population and development of large cities, as well as the increase of industrial, commercial and social activities near the coast (Pelling and Blackburn, 2013), including recently boosting sectors of the so-called sea economy, such as the ones related to marine renewable energy and aquaculture, among others. In this context, the present journal issue provides a unique set of works dedicated to the analysis of several environmental risks and impacts, which represent paradigmatic cases that have a profound impact on the sustainable and integrated management of coastal resources. there is a complete absence of management and contingency plans, while in the portion of of were in the by the oil municipalities and 7 The conducted analysis showed that none of these cases had a management and contingency plan covering the chemical impacts related to oil spilling, which in turn leads to unprepared populations and authorities in case of a disaster. This study concludes with recommendations to update the management and contingency plans of coastal regions in Brazil and provides a benchmark study that can be useful for other nations and municipalities with heavy oil and maritime traffic related activities.

ASBTRACT The present investigation used Brachionus plicatilis (Rotifera) to evaluate the water quality in Callao Bay, Peru. The water samples were taken in four areas: P1 in La Punta, P2 in Chucuito, P3 in front of the Callao Port Terminal and P4 in the San Lorenzo and El Frontón Islands, and in four seasonal periods: autumn-2015, winter- 2015, spring-2015, and summer-2016. Physical-chemical parameters, chlorophyll, phycocyanin, heavy metals, and bioassays with seawater at 24 h and 48 h of exposure to Brachionus plicatilis obtained from a standardized culture were evaluated in each area and seasonal period. High concentrations of Ag, Pb, Hg, Cu, Cr, Ni and Zn were found at all the sampling sites. The no observed effect concentration (NOEC) values (concentration at which a significant effect of mortality is not observed with respect to the control) and lowest observed effect concentration (LOEC) (minimum concentration at which a significant effect of mortality is observed with respect to the control) at 48 h of exposure to the B. plicatilis bioassay were lower for P1 (winter-2015) and P2 (winter-2015). Principal components analysis (PCA) showed that principal component 1 (PC1) contributed 38.70% and PC2 17.70%. PC1 was formed by LOEC of Cd, Hg, Ni, Ag, and Pb while PC2 was related to Cu, Cr and Zn. According to these results Brachionus plicatilis can be used as a bioindicator organism to assess water quality in the marine environment. Keywords: acute bioassay, Brachionus, heavy metals, mortality, rotifer.

Na transição tropical-subtropical, no litoral norte do estado de São Paulo (Brasil), a presença de um porto e um terminal petrolífero, associados a outras atividades humanas como pesca, turismo e industrialização, pressionam a integridade ecológica e a biodiversidade do arquipélago de Alcatrazes, que compreende duas áreas marinhas protegidas (ESEC Tupinambás e REVIS Alcatrazes). Este trabalho tem como objetivo a elaboração de uma carta de sensibilidade ambiental ao derramamento de óleo (carta SAO) para subsidiar a proteção dessas unidades de conservação. A carta SAO utilizou dados primários da ictiofauna demersal e dados secundários para outras variáveis biológicas, socioeconômicas e oceanográficas. O mapa operacional produzido (escala 1: 50000) destaca pontos estratégicos de importância biológica e para as atividades desenvolvidas em Alcatrazes. As regiões abrigadas do arquipélago, compostas por falésias expostas com menor declive, ou rochas protegidas da ação das ondas, apresentaram os maiores índices de sensibilidade ambiental. A biodiversidade de Alcatrazes apresenta 835 táxons, e muitos são considerados ameaçados, de acordo com diferentes níveis de proteção, ou por seu endemismo ou por serem espécies comercialmente importantes. As áreas marinhas protegidas não estão necessariamente seguras contra derramamentos de óleo que ocorram além de seus limites geográficos, tornando a carta SAO do arquipélago de Alcatrazes uma ferramenta essencial para ações de combate a derramamentos de óleo, para a elaboração de planos de contingência, e como uma fonte de dados para trabalhos futuros.

Land transformation is the main factor that may increase ecological vulnerability in coastal areas in Semarang City, Indonesia. Therefore, environmental damage in coastal areas should be restored using an integrated management strategy based on the ecosystem, social and economic condition, as well as stakeholder partnership. This research aimed to measure the resilience score of environmental and socio-economic conditions and to identify stakeholder partnership in arranging integrated coastal area management in Semarang City. A descriptive observational study was conducted in Mangkang Kulon and Tugurejo Sub-district, Tugu District, Semarang City using in-depth interviews, field observations and survey-mapping. The ecological conditions data was collected using image analysis of aerial photographs following the concept of environmental and geophysical. Meanwhile, the social-community conditions data were diagnosed using a socio-economic assessment. The result showed that changes in the coastline occured due to the disappearance of some area of mangrove that were turned indented close to the ocean. However, the socio-economic index showed a medium to a high score, which means high opportunities for the local community to develop their livelihood. Therefore, various community empowerment programs initiated by government, academics, the private sectors, and non-government organizations have increased the resilience of the community.

La zona costera constituye un espacio singular por la compleja interacción que ejercen los dominios oceánico, terrestre y aéreo. Para la planificación y gestión ambiental es fundamental delimitar el espacio terrestre donde se originan los procesos naturales que definen la influencia del dominio oceánico, así como las características socioeconómicas que modulan el proceso de gobernanza. Con el objetivo de definir bajo condiciones de insularidad algunos criterios básicos e identificar los principales descriptores de posible uso en la delimitación del espacio comprendido entre el borde litoral y el limite interior de la faja terrestre sometida a la influencia oceánica, se efectuó un ejercicio grupal con 25 especialistas de las Ciencias de la Tierra. Los juicios se relacionaron a la litología, tectónica, relieve, clima, suelos, paisajes, ecosistemas y hábitats así como a los peligros, vulnerabilidades y riesgos. A microescala, fueron identificados 24 descriptores, a mesoescala 25 y a macroescala 28. Se reconoció la importancia que todos ellos tienen para la delimitación de ese espacio, en particular los vinculados al paisaje y al relieve, concluyendo que la magnitud del proceso de antropización, determina la importancia relativa de los mismos. Cuando la naturalidad es elevada, los límites de las formaciones vegetales adquieren notoria importancia, pero cuando la “litoralización” es total solo las conurbaciones y los factores de riesgo determinan la extensión de esta faja terrestre. La identificación de este espacio geográfico resulta de gran importancia ya que su conservación o recuperación depende del transporte de materia y contaminantes derivado del escurrimiento terrestre, particularmente de aquel proveniente de las cuencas hidrográficas asociadas, casi siempre con un notable deterioro ambiental.

Con el objetivo de definir bajo condiciones de insularidad algunos criterios básicos e identificar los principales descriptores de posible uso en la delimitación del espacio comprendido entre el borde litoral y el limite interior de la faja terrestre sometida a la influencia oceánica, se efectuó un ejercicio grupal con 25 especialistas de las Ciencias de la Tierra. Los juicios se relacionaron a la litología, tectónica, relieve, clima, suelos, paisajes, ecosistemas y hábitats así como a los peligros, vulnerabilidades y riesgos. A microescala, fueron identificados 24 descriptores, a mesoescala 25 y a macroescala 28. Se reconoció la importancia que todos ellos tienen para la delimitación de ese espacio, en particular los vinculados al paisaje y al relieve, concluyendo que la magnitud del proceso de antropización, determina la importancia relativa de los mismos. Cuando la naturalidad es elevada, los límites de las formaciones vegetales adquieren notoria importancia, pero cuando la “litoralización” es total solo las conurbaciones y los factores de riesgo determinan la extensión de esta faja terrestre. La identificación de este espacio geográfico resulta de gran importancia ya que su conservación o recuperación depende del transporte de materia y contaminantes derivado del escurrimiento terrestre, particularmente de aquel proveniente de las cuencas hidrográficas asociadas, casi siempre con un notable deterioro ambiental.","PeriodicalId":37892,"journal":{"name":"Journal of Integrated Coastal Zone Management","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71208707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Identificar áreas alagáveis nas Zonas Costeiras (ZCs) é essencial para a elaboração de planos de gestão capazes de minimizar os impactos associados à elevação do Nível Global Médio do Mar (NGMM). O objetivo deste trabalho foi projetar a vulnerabilidade e susceptibilidade à intrusão marinha em São João da Barra/RJ, considerando dois cenários previstos pelo Painel Intergovernamental sobre Mudança Climática (IPCC) para o período 2081-2100: “otimista” (elevação do NGMM de 0.26 a 0.55 m) e “pessimista” (0.45 a 0.82 m). Através do software QGis foi construído um banco de dados para a representação das unidades de paisagem e a ponderação de variáveis que condicionam as inundações. Dos 453.00 km2 de território são-joanense até 193.01 km2 (42.60%) e 253.38 km2 (55.85%) podem ser inundados nos cenários “otimista” e “pessimista”, respectivamente. A elevação no intervalo 0.26-0.82m pode tornar inundável até 16.46 km2 (42.81%) dos 38.44 km2 da RPPN Caruara e até 60% (11.52 km2) dos 19.20 km2 do Porto do Açu. As áreas de maior vulnerabilidade ambiental concentram-se nos manguezais. As regiões mais afetadas economicamente nos dois cenários são aquelas onde vivem os agricultores familiares. Com base nos resultados obtidos, é possível concluir que devido às suas configurações geológicas e ambientais, a ZC são-joanense é vulnerável à elevação do NGMM, com maiores reflexos sobre áreas urbanas e rurais de baixa altitude e em ecossistemas naturais. Até 2100 o município poderá perder mais da metade de sua área territorial e caso não sejam tomadas ações de contingenciamento, haverá grandes perdas econômicas e ambientais.
