TL;DR: In this article, the authors investigated the link between people's vulnerability in the face of coastal hazards and sustainable livelihoods and found that local fishermen are often compelled to go out fishing despite pending typhoon or storm surge to sustain the daily needs of their family.
Abstract: The present study investigates into the link between people’s vulnerability in the face of coastal hazards and sustainable livelihoods. It focuses on the town of Borongan in the Philippines and draws on questionnaire-based surveys and focus group discussions. This research shows that local fishermen are often compelled to go out fishing despite pending typhoon or storm surge to sustain the daily needs of their family. Its also demonstrates that the capacity of these people to protect themselves from the threat is constrained by poor and fragile livelihoods. In the event of a crisis, the study argues that people resort to a range of adjustments on their daily life which is rooted in the strength and diversity of their livelihoods. To reduce people’s vulnerability and enhance capacities to face coastal hazards, the study fosters Community-Based Disaster Risk Reduction with special emphasis to sustainable livelihoods.

TL;DR: In this article, an interpretative framework for the conflictual processes relating to the environment is proposed, in order to provide a complementary analysis of the typologies of existing conflicts and to highlight the socio-spatial dynamics of conflicts of use relating to environment.
Abstract: Most rapidly changing areas are beset by intensified conflicts of use, where the environmental dimension plays an increasingly important role. These antagonistic situations represent a challenge for continuing and launching territorial public actions for integrated resource management. This contribution aims to highlight the socio-spatial dynamics of conflicts of use relating to the environment and provides methodological elements to characterise the conflictual processes at work in rapidly changing areas. It sets out elements of research on the Languedoc-Roussillon coastal zone, based on the hypothesis that sustainable management of territories’ gains by being acquainted with conflict mechanisms (the emergence factor, modes of dissent, methods of regulation) and the actors involved (role, organisation, strategies), in time and in space. An interpretative framework for the conflictual processes relating to the environment is proposed, in order to provide a complementary analysis of the typologies of existing conflicts.

TL;DR: The Countryside Council for Wales (CCW) is developing a management framework with the primary aim of restoring favorable conservation status to the sand dune resource of Wales as mentioned in this paper, which will take onboard the requirements of both national and international conservation legislation and also help CCW integrate its responsibilities for biodiversity, geodiversity, landscape, access and recreation for this habitat.
Abstract: The Countryside Council for Wales (CCW) is developing a management framework with the primary aim of restoring favourable conservation status to the sand dune resource of Wales. It will take onboard the requirements of both national and international conservation legislation and will also help CCW integrate its responsibilities for biodiversity, geodiversity, landscape, access and recreation for this habitat. In order to achieve certain conservation goals it will be necessary to have in place a variety of different types of management ranging from non- or minimal intervention through to intensive single species management and habitat re-creation. However, it will not provide a comprehensive framework for all aspects of site management, but only those that are deemed to be of strategic importance, and have significance within an all-Wales perspective for their nature conservation importance.

TL;DR: In this article, the authors examined the distribution of Balaenoptera acutorostrata in the waters of the outer Moray Firth in northeast Scotland (57o41'N 2o40'W) during the summer and autumnal months.
Abstract: The coastal waters of the Moray Firth in northeast Scotland (57o41’N 2o40’W) provide rich, inshore feeding grounds for minke whales (Balaenoptera acutorostrata) during the summer and autumnal months. In order to better understand the habitat selection, movements and feeding ecology of the animals utilising this North Sea region, distribution data from the southern coastline of the outer Moray Firth were subsequently examined with respect to the marine physiography of the area, specifically the environmental variables water depth, slope, aspect and sediment-type. A total of 305 minke whale encounters – collected from dedicated boat surveys conducted between May and October 2001 to 2006 inclusive – were used in the construction of a Geographic Information System (GIS) for the 860 square-km study site. The subsequent analysis revealed a strong spatial preference by whales in this location for water depths between 20 and 50 metres (mean 46.9 m, SD = 30.9), steep slopes (mean 75.7 degrees, SD = 8.9), a northerly-facing aspect and sandy-gravel sediment type. Kruskal-Wallis tests for variance confirmed that the distribution of B. acutorostrata was significantly different across each of these physiographic features examined (P < 0.05). In particular, water depth and sediment type were shown to be highly correlated with the frequency of whales observed (Spearman’s Rank Correlation P < 0.05 for depth and sediment respectively). From these results, we conclude that sea bottom characteristics may be used to predict the fine-scale distribution of minke whales on their feeding grounds; the physiographic features identified providing valuable proxies for inferring prey distributions in the absence of fisheries data. However, an appreciation of both abiotic and biotic factors (using a combination of GIS and remote sensing outputs) is clearly desirable for ecosystem-based management approaches for the coastal conservation of these whales. The application of GIS capacities to ecological studies based largely on field data of these marine mammals is highly recommended in the present study to cetologists, environmental modellers and conservation managers alike.

TL;DR: In this paper, the authors focused on a rural coastal area in Japan and examined whether VDPO impacts residents' awareness of disaster preparedness and also examines ties among the community.
Abstract: The Japanese rural coastal areas are inherently vulnerable to typhoons and tsunamis. Their vulnerability has been further increasing recently, in part due to social factors such as the aging of society and depopulation. Following the Kobe earthquake of 1995, the Japanese government has promoted the Voluntary Disaster Preparedness Organization (VDPO) to build communities that are more sustainable and resilient to natural disasters. However, studies indicate that some VDPO activity has stagnated. The present study focuses on a rural coastal area in Japan and examines whether VDPO impacts residents’ awareness of disaster preparedness and also examines ties among the community. The study relies on a questionnaire survey. It reveals that VDPO contributes to improving both awareness of disaster preparedness and ties in the community.

TL;DR: The habitats of La Mancha Lagoon, located midway along the coast of Veracruz, Mexico, are responding to the change of sediment supply reaching its primary inlet at the Gulf of Mexico as mentioned in this paper.
Abstract: The habitats of La Mancha Lagoon, located midway along the coast of Veracruz, Mexico, are responding to the change of sediment supply reaching its primary inlet at the Gulf of Mexico. Until several decades ago, an abundant alongshore supply of sediment created a periodic opening and closing of the La Mancha inlet. The hydrologic regime of the lagoon consisted of raised water level and lower salinity during the closures, whereas the open inlet favored lower water level, higher salinity, and sediment accumulation in the flood tidal delta. Currently, diminished alongshore sediment supply has affected the inlet morphology and the discharge regime. Associated with the reduced sediment supply, the inlet is open longer in its periodic cycle, the water level variation is reduced, the salinity contrasts are reduced, and the rate of sedimentation in the flood-tide delta is increased. This combination of alterations to the inlet area is changing the flooding regime and affecting the conditions in a very well-developed mangrove habitat at the lagoon margins as well as conditions within the aqueous portions of the lagoon. Management options produce a conflict between supporting the direction of change or preserving the existing habitats.

TL;DR: In this article, the authors monitored the salt marsh succession after de-embankment on the East Frisian barrier island Langeoog by investigating permanent plots and found that the former high marsh and glycophytic vegetation died out and was replaced by species of lower salt marsh zones.
Abstract: Salt marsh succession after de-embankment was monitored on the East Frisian barrier island Langeoog by investigating permanent plots. Seventy years after embankment salt marsh plants were once again influenced mainly by the tidal regime. From 2002 to 2004 the former high marsh and glycophytic vegetation died out and was replaced by species of lower salt marsh zones. Nitrophytic halophytes like Suaeda maritima, Atriplex prostrata and Artemisia maritima established first because of the high nutrient content in the soil, a direct result of former vegetation decay. With decreasing nitrogen afterwards other species became more competitive. Until 2007 Atriplex portulacoides became more dominant in the lower marsh and Elymus athericus reached dominance in areas where grazing has been abandoned in the high marsh. The dynamics in the study area is much lower than in natural marshes due to the still existing drainage system. Therefore vegetation units with low species diversity are widespread.

TL;DR: In this article, an attempt at reviewing this relatively unknown problem through the results of an international bibliographical review and of a regional inquiry conducted in close collaboration with managers of the conservation areas in Brittany is made.
Abstract: Bird disturbance by human activities is one of the impacts related to human presence at conservation sites in Brittany (France). This paper is an attempt at reviewing this relatively unknown problem through the results of an international bibliographical review and of a regional inquiry conducted in close collaboration with managers of the conservation areas in Brittany. These two approaches will help to demonstrate the extent and complexity of the human / fauna interactions, as well as to take stock of the state of research in this field and, last but not least, to highlight the difficulties managers of conservation sites are facing to deal with this new issue. For the managers, bird disturbance is indeed the most important impact related to human attendance on conservation sites in Brittany.

TL;DR: It is essential that the strategic principles are given priority, because only they can underpin a sustainable approach to the issue of coastal erosion, and they are an indivisible integrated set.
Abstract: The European Recommendation on Integrated Coastal Zone Management has six core principles. These form two groups, one concerned with strategic goals and one that has a local focus. The principles are presented as a menu of free-standing options, with no prioritization either within or between groups. In the case of coastal erosion management these characteristics result in irreconcilable conflicts, and actively hinder sustainable management of eroding coasts. The principles require clarification, and recognition that they are an indivisible integrated set which should not be used to select principles to advance a particular agenda. It is essential that the strategic principles are given priority, because only they can underpin a sustainable approach to the issue of coastal erosion.

TL;DR: Services and systems developed in the FP6 InterRisk (Interoperable GMES Services for Environmental Risk Management in Marine and Coastal Areas of Europe) project are presented, which addresses the need for better access to information for risk management in Europe.
Abstract: This paper presents services and systems developed in the FP6 InterRisk (Interoperable GMES Services for Environmental Risk Management in Marine and Coastal Areas of Europe) project, which addresses the need for better access to information for risk management in Europe, both in cases of natural hazards and industrial accidents. The overall objective of the project is to develop a pilot system for interoperable GMES monitoring and forecasting services for environmental management in marine and coastal areas. This pilot system is based on established and widely adopted web-GIS standards, in line with INSPIRE recommendations. The pilot is comprised of, among other things, a portal and a web-GIS map viewer, both developed using open source tools. Providers using commercial tools adhering to the adopted standards, however, can also deliver products to the InterRisk pilot. The InterRisk services and system are based on a combination of free and commercial software, and have been demonstrated to end-users in three European areas: Norwegian, UK and Irish waters, and German and Polish waters. Products and services offered in these areas are presented, along with an outline of the technical development of web-GIS clients and portals.

TL;DR: In this paper, a bottom-up approach based on the inductive description and assessment of problems is combined with a top-down approach including the deductive differentiation of an integrative sustainable development model.
Abstract: The article describes the approach chosen for the development of indicators for an ICZM in the Oder estuary region (Germany, south-western Baltic Sea). The development of indicators focuses on regional problems. A bottom-up-approach based on the inductive description and assessment of problems is combined with a top-down-approach including the deductive differentiation of an integrative sustainable development model. At the interface of the problem-orientated bottom-up-approach and the norm-orientated top-down-approach, indicators specify the issues discussed. This means linking the minimum demands made by sustainable development to the specific regional problems. The regional approach provides the following results: a high degree of orientation towards existing problems and user needs, the vertical integration of the issues discussed at the international and European level, and links to the concept of sustainability.
TL;DR: In Italy, the incapability of the State to implement a national strategy for the sustainable development of coastal areas lead the regional authorities to adopt integrated coastal zone management plans, which are often relevant, correcting the defiency of the national legislation, but do not assure the implementation of a coherent littoral policy as mentioned in this paper.
Abstract: In Italy, the incapability of the State to implement a national strategy for the sustainable development of coastal areas lead the regional authorities to adopt integrated coastal zone management plans. These initiatives are often relevant, correcting the defiency of the national legislation, but do not assure the implementation of a coherent littoral policy. Thereby, it is to be hoped that the recent developments in international law—and particularly the Mediterranean protocol on integrated coastal zone management recently adopted—will compel the Italian State to make a positive commitment to coastal protection.
TL;DR: In this article, a mathematical model for defining set-back lines along eroding coasts is presented. But the model is applied to the Frontignan and Carnon beaches (south of France).
Abstract: The study presented here describes a method for defining set-back lines along eroding coasts. The method (a mathematical model) combines the long-term shoreline retreat trend with short-term shoreline erosion (during storms). Simulations are carried out for 2030 and compared with the beach width to determine whether the shoreline is likely to shift onshore. The mathematical model is applied to the Frontignan and Carnon beaches (south of France). Both sites possess hard engineering coastal structures and downdrift erosion on the natural beaches. The set-back lines indicate that beaches with groynes are generally wide enough to resist shoreline retreat, while the downdrift “natural” beaches are not. We discuss the possible utilisation of set-back line estimations.
TL;DR: In this paper, a study of mangrove vegetation structure in the Gulf of Kachchh was carried out over two years (1999-2000) at three sites, including tree density, tree height, tree girth at breast height (GBH), canopy index, regeneration class and recruitment class, together with physico-chemical characteristics of water and sediment and the textural aspects of sediments.
Abstract: To understand natural and anthropic control of mangrove vegetation in the Gulf of Kachchh, a study was undertaken of its vegetation structure. Over 2 years (1999–2000) at three sites, mangrove vegetation was studied, including tree density, tree height, tree girth at breast height (GBH), canopy index, regeneration class and recruitment class, together with physico-chemical characteristics of water and sediment and the textural aspects of sediments. Reflecting the hot, arid hinterland of Gujarat, ambient temperatures and salinities are high in this macrotidal estuary, decreasing somewhat during the monsoon. The littoral soil supporting the mangrove is abundant in silty loam, silty clay and slity clay loam. The density of mature trees (Mangrove plants of GBH > 25 cm) ranged from 2088/ha to 3011/ha, the height of the trees ranged from 1.42 m to 9 m and the maximum mean GBH at all three sites was 33 cm, and the mean canopy indices ranged between 4.77 m2 and 10.45 m2. The maximum density of regeneration stages was 100,800/ha while that of recruitment stages was only 3,040/ha. While quite severely impacted by anthropic exploitation at one site, the mangrove ecosystem of Gulf of Kachchh was found to be mainly healthy and supporting associated organisms. The ecological and social role of the mangrove, and the potential for its future conservation are briefly discussed in the light of current legislation.
TL;DR: Investigation of ecological mechanisms related to the observed pattern of floristic diversity and nestedness in the Lake Bardawil islets on the Mediterranean coast of Sinai Peninsula before the execution of the North Sinai Agricultural Development Project (NSADP) that will threaten the ecosystem of the lake yielded evidence for a positive species-area relationship.
Abstract: Island biogeography theory and nestedness are two relevant and important concepts in biogeography and conservation. However, their integration and application has not been examined for maintaining or maximizing species diversity, especially in arid regions. The aim of this study is to investigate the ecological mechanisms related to the observed pattern of floristic diversity and nestedness in the Lake Bardawil islets on the Mediterranean coast of Sinai Peninsula before the execution of the North Sinai Agricultural Development Project (NSADP) that will threaten the ecosystem of the lake. Plant species on 15 islets were identified and categorized into ecological groups related to their life-form, salt tolerance and succulence. Richness of total plant species and their ecological groups were positively correlated with islet area, number of habitats and elevation, and negatively with disturbance index. The temperature calculator detected highly significant nestedness for the entire flora and all ecological groups. Distance from the mainland had no effect on either species richness or nested pattern of total plant species and their ecological groups. Both the analyses of species richness and nested distribution yielded evidence for a positive species-area relationship. Although nestedness was detected for the entire plant species and their ecological groups, many species and islets exhibited idiosyncratic distribution. Idiosyncrasies could be mainly attributed to demographic stochasticity which is an important character for species interaction and diversity maintenance in arid regions. Therefore, in developing conservation strategies for the Lake Bardawil islets, it is important to incorporate spatial and temporal stability of populations.
TL;DR: In this paper, an integrated coastal management project on an island, Isle-aux-Coudres, located in the St-Lawrence Estuary (Quebec, Canada).
Abstract: This paper is about an Integrated Coastal Management Project on an island, Isle-aux-Coudres, located in the St-Lawrence Estuary (Quebec, Canada). It is based on data collected from 2003 to 2007 on the participatory aspects of the project such as: types of stakeholders, relationships between stakeholders, time dedicated to dialogue, consensus versus negotiation, and outcomes. We analyze the way concerns evolved into actions and the relationship between dialogue and actions during the project. We conclude that the difficulty is to join together the differences around various stakes, without forcing the consensus, or negating problems and conflicts.
TL;DR: In this paper, the vegetation dynamics on the Łeba Bar/Poland over a period of 74 years by cartometric comparison using modern Geographical Information System (GIS) were identified.
Abstract: Coastal dune ecosystems are among the most dynamic habitats with high conservation value in Europe but are also under strong anthropogenic pressure regarding coastal protection and recreation. Hence, it is of high importance to know about long-term natural and anthropogenic changes and development of protected dune habitats for nature conservation, as well as for coastal management. This paper aims to identify the vegetation dynamics on the Łeba Bar/Poland over a period of 74 years by cartometric comparison using modern Geographical Information System (GIS). To quantify the rate of vegetation dynamics two aerial photographs dating from 1932 and 2006 were digitalized and analyzed with GIS to produce digital vegetation maps. Information about decrease, increase and stability of vegetation types of this area are discussed. The results show that there has been a clear reduction in the total area of bare sand and a considerable increase of woodlands and dense grass communities. Nevertheless, the remaining extensive drift sand areas and deflation hollows on the Łeba Bar offer one of the most important habitats for pioneer vegetation on bare sand of migrating dunes and dunes at the Southern Baltic coast. The present work proved the need to observe the future development of the vegetation communities and to implement management measures to maintain the dynamic of this unique dune landscape.
TL;DR: In this paper, the authors provided information on selected sites as possible sources of suitable sand, chemical and granulometric characteristics of their sand, and the potential direct and long-term environmental effects and consequences of its use in any future nourishment practices.
Abstract: The coastal zone management and development plans which include tourism development necessitate among many other management practices, the extension of the available area of the present natural but narrow, limited and widely eroded beaches by implementing some type of nourishment practices. The present work is providing information on selected sites as possible sources of suitable sand, chemical and granulometric characteristics of their sand, and the potential direct and long-term environmental effects and consequences of its use in any future nourishment practices. Seven sites located within the up-lifted terraces area along the Jordanian portion of the Gulf of Aqaba, were selected as potential sources or borrow sites for sand that may be used in any future nourishment projects. Two sites were selected at the northeastern side of Aqaba region to represent sand dunes. Sand material from these sites were analyzed for their physical characteristics (grain size) as well as their content of heavy metals, organic carbon, total nitrogen, total phosphorous, and calcium carbonate. Standard methodological techniques were used during analysis of all constituents. The results were compared with those obtained from the analysis of sand deposits of six beaches along the Jordanian coastline of the Gulf of Aqaba. Results indicate that sand of the selected borrow sites has grain size fractions that are suitable for use in beach nourishment. Results of the measured pollution indicators indicate that their levels in the sand of the potential borrow sites are within or lower than their levels in the marine and coastal sediments of the Gulf of Aqaba and the Red Sea. These properties, in addition to the wide occurrence and availability of such sources along the coasts of the Red Sea and the Gulf of Aqaba, suggest that it will be a cheep source of sand for beach extension and restoration and their use in large amounts in beach nourishment project will not pose major hazards on the quality of seawater of the Gulf of Aqaba area
TL;DR: In this article, a survey carried out of 20 seaside tourism professionals and representatives of local institutions aimed to understand the underpinning strategies of these developments, which are very heterogeneous as regards their size, their localization, and their level of service.
Abstract: Faced with a growing demand from the disabled community in Europe and encouraged by new regulations regarding people with disabilities, the French Riviera has joined an initiative which makes its seaside facilities more accessible. Adapted amenities are consequently currently available on the French Riviera. A survey carried out of 20 seaside tourism professionals and representatives of local institutions aimed to understand the underpinning strategies of these developments, which are very heterogeneous as regards their size, their localization, and their level of service. On the whole, it seems that on the French Riviera the services offered to disabled tourists are the product of a mixture of willingness and obligation by the regulations. Disabled people are not yet considered as real clients but as a separate population, not to be mixed with the able-bodied holiday clientele.
TL;DR: The mangrove forests in the South Viet-Nam are the witnesses of a destruction then of a cicatrization of the landscapes as discussed by the authors, and the possible reconquest of the littoral by the plants is due to the great capacity of nature to be regenerated.
Abstract: French colonization (1860–1945), Indochina (1945–1954) and Viet-Nam’s Wars (1961–1975) illustrate during nearly one century, the use of the littoral at “strategic” ends (commercial and military). The discovery of the coasts of Cochinchina allowed the conquest of new grounds and the progressive development of the primarily alluvial plains. The mangrove forests in the South Viet-Nam are the witnesses of a destruction then of a cicatrization of the landscapes. A progressive dynamics and a reconquest of formerly bombarded lands, intensely defoliated, set up themselves. We can speak about “rebirth” because it is possible to see, rebuild this dynamics as from one moment “zero” (war) and to compare with the evolution of the current vegetable formations, using Remote Sensing and Geographical Information Systems (GIS). These devasted landscapes were transformed into a success, by positive effect of the rehabilitation of the coasts. Finally, the possible reconquest of the littoral by the plants is due to the great capacity of nature to be regenerated.
TL;DR: In this paper, the authors describe the perception of the Opal Coast (North of France) among French native populations or remaining population for tourist reasons, based on quantitative and qualitative equivalences and differences on perceiving the characteristics and love of the area according to nationality.
Abstract: The purpose of the exploratory study is to describe the perception of the “Opal Coast (North of France)” among French native populations or remaining population for tourist reasons. A discussion (a) based on quantitative and qualitative equivalences and differences on perceiving the characteristics and love of the area according to nationality is proposed (b) confronting the perceptions measured of the national stereotypes is evoked, (c) considering the tourist communication in the area as a self confirmation of the identity of the tourist visiting is outlined.
