Factors Influencing Adaptive Marine Governance in a Developing Country Context: a Case Study of Southern Kenya
Provedor de dados: Ecology and Society
Autores: Evans, Louisa S.; The School of International Development, University of East Anglia; louisa.evans@jcu.edu.au; Brown, Katrina; The School of International Development, University of East Anglia; k.brown@uea.ac.uk; Allison, Edward H.; The WorldFish Center; e.allison@cgiar.org.
Adaptive governance can be conceptualized as distinct phases of: 1) understanding environmental change; 2) using this understanding to inform decision making; and 3) acting on decisions in a manner that sustains resilience of desirable system states. Using this analytical framework, we explore governance in practice in two case studies in Kenya, that reflect the &amp;#8220;messiness&amp;#8221; of contemporary coastal governance in many developing country contexts. Findings suggest that adaptive marine governance is unlikely to be a smooth process of learning, knowledge sharing, and responding. There are institutional, sociocultural, and political factors, past and present, that influence each phase of both local and state decision making. New local...

Influence de l'azote et du phosphore sur la croissance et la toxicité de Prorocentrum lima (Ehrenberg) Dodge
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Morlaix, Martine; Lassus, Patrick.
Very few attempts have been made in order to investigate the role of nutrients on cellular growth and toxin production in dinoflagellates associated with DSP (Diarrhetic Shellfish Poison). Some preliminary results are presented here, aiming at a better knowledge of inorganic nitrogen and organic phosphorus effects upon division rate and toxin content of Prorocentrum lima (PL2V spanish strain). Nitrogen have a positive effect on growth rate, up to a threshold value of 880muM.l-1. Above this threshold the rate decreases. There is no effect on toxin content since okadaic acid and DTX1 cell contents remain low (4.8 +/- 0.5 pg.cell.-1) and steady. Phosphorus effect upon division rate follows a non-linear relationship, whereas cellular toxic content is inversely...

Cycle du mercure en estuaire, baie de Seine et pays de Caux
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Laurier, Fabien.
The Seine estuary and its adjacent region Pays de Caux are two significant sources of mercury for coastal marine environments. It is carried through fluvial means for the Seine bay and through karstic fresh water emergences for Pays de Caux's coastal area.  Mercury cycle in the Seine estuary and bay is affected by additional anthropical activities. The estuary's maximal turbidity area acts like a trap and a chemical reactor for fluvial mercury. Within this area, we can confirm: (i) the non conservative behaviour of dissolved mercury; (ii) mercury enrichment of particles when comparing the Seine's and marine environment and we suggest mercury particle redistribution from the organic fraction to the oxyhydroxydes fraction. A large fraction of mercury is...

In the marine environment, positive law generates multiple zones and regulatory limits that overlap in space, justifying a cartographic representation as a relevant approach to promote understanding (synthetic vision), analysis (highlighting legal anomalies, inconsistencies and redundancies), dissemination and communication to different audiences (awareness-raising). The article presents a methodology leading to the mapping of marine and coastal environmental law in West Africa, using a geographic information base to produce static or interactive cartographic representations via a Geographic Data Infrastructure (GDI). It shows the contribution of this type of mapping to a transversal approach in a multi-activity, multi-sectoral and multi-scale context. A...

Bathymetric estimation using MERIS images in coastal sea waters
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Minghelli Roman, Audrey; Polidori, Laurent; Mathieu-blanc, Sandrine; Loubersac, Lionel; Cauneau, François.
Bathymetric estimation using remote sensing images has previously been applied to high spatial resolution imagery such as CASI, Ikonos, or SPOT but not on medium spatial resolution images (i.e., MERIS). This choice can be justified when there is a need to map the bathymetry on large areas. In this letter, we present the results of the bathymetry estimation over a large known area, the Gulf of Lion (France), expanding over 270 x 180 km.

Relations entre apports terrigènes et conchyliculture dans les Pertuis Charentais
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Soletchnik, Patrick; Polsenaere, Pierre; Le Moine, Olivier; Guesdon, Stephane; Bechemin, Christian.
This work presents interactions between quantitative and qualitative river freshwater inputs and the shellfish farming (oyster and mussel) in the Pertuis Charentais. The quantity of freshwater (i.e. salinity) seems to have a weak influence on the shellfish farming contrarily to its quality determined by particulate and dissolved matters contained in the water. In autumn and winter, large precipitations have a "globally positive" effect amending the coastal ecosystem. Associated dissolved nutriments and the organic matter largely determine the quality of the coming spring growth for bred shellfish, itself controlling in turn the annual yield efficiencies. However, in winter their effects are postponed because of strong mineral load, low luminosity and...

The Contribution of Wind-Generated Waves to Coastal Sea-Level Changes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dodet, Guillaume; Melet, Angélique; Ardhuin, Fabrice; Bertin, Xavier; Idier, Déborah; Almar, Rafael.
Surface gravity waves generated by winds are ubiquitous on our oceans and play a primordial role in the dynamics of the ocean–land–atmosphere interfaces. In particular, wind-generated waves cause fluctuations of the sea level at the coast over timescales from a few seconds (individual wave runup) to a few hours (wave-induced setup). These wave-induced processes are of major importance for coastal management as they add up to tides and atmospheric surges during storm events and enhance coastal flooding and erosion. Changes in the atmospheric circulation associated with natural climate cycles or caused by increasing greenhouse gas emissions affect the wave conditions worldwide, which may drive significant changes in the wave-induced coastal hydrodynamics....

Autores: Oursel, B.; Garnier, C.; Pairaud, Ivane; Omanovic, D.; Durrieu, G.; Syakti, A. D.; Le Poupon, C.; Thouvenin, Benedicte; Lucas, Y.
The evaluation of contaminant net fluxes from the coast to the open sea requires the study of terrigeneous particles behaviour and fate. We studied the particles issued from two small coastal rivers whose waters are mixed with treated wastewater (TWW) coming from the Marseille wastewater treatment plant (WWTP) just before discharge to the Mediterranean Sea. An experimental device was developed and used to investigate particles settling rates, size distribution and metallic contamination when mixing with seawater. The particles were sampled in flood deposits of rivers and outlets during rainy periods and in the outlet water during dry periods. The flood deposits were mainly composed of 50–200 μm-sized particles, higher metals content being observed in the...

Autores: Caill-milly, Nathalie; Mahias, Jérémy; Bru, Noelle; De Casamajor, Marie-noelle; Pigot, Thierry; Corbet, Paul.
This paper investigates whether morphological variability of test and Aristotle’s lantern can be detected in sea urchins exposed to domestic pollution and whether this variability can be also related to tidal level and hydrodynamic features. The study was conducted on four sites along the French Basque coast. Each site is characterized by its geological layers’ orientation, regardless of its proximity to sewage outlets. Analyses on high-resolution pictures of jaws were performed and three parameters were retained: length, height and demipyramid dry mass. Five shape descriptors were consequently defined regarding the test and the jaws. Individuals with heavy test density associated with highly developed demipyramid regarding test diameter and height were...

Physiological basis of interactive responses to temperature and salinity in coastal marine invertebrate: Implications for responses to warming
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Torres, Gabriela; Charmantier, Guy; Wilcockson, David; Harzsch, Steffen; Giménez, Luis.
Developing physiological mechanistic models to predict species’ responses to climate‐driven environmental variables remains a key endeavor in ecology. Such approaches are challenging, because they require linking physiological processes with fitness and contraction or expansion in species’ distributions. We explore those links for coastal marine species, occurring in regions of freshwater influence (ROFIs) and exposed to changes in temperature and salinity. First, we evaluated the effect of temperature on hemolymph osmolality and on the expression of genes relevant for osmoregulation in larvae of the shore crab Carcinus maenas. We then discuss and develop a hypothetical model linking osmoregulation, fitness, and species expansion/contraction toward or away...

Dynamique du carbone et des nutriments dans la zone côtière Baie de l’Aiguillon-Pertuis Breton et influence des apports terrestres du bassin versant du Marais poitevin
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lannuzel, Reva.
Coastal zones represent key systems in biogeochemical cycle couplings between continents, oceans and the atmosphere transporting considerable amounts of matter, energy and nutrients (C, N, P et Si) from land to sea. Despite its relatively modest surface area (7 % of the global ocean surface), this zone accounts for 14–30 % of all oceanic primary production. The present study deals with nutrients and carbon dynamics during a full hydrologic cycle in 2017 over the terrestrial-aquatic continuum formed by the Poitevin Marsh-Aiguillon Bay- Breton Sound to better understand terrestrial export influence on the coastal zone. Carbon and nutrient concentrations were sampled twice a month over heterogeneous sites (estuaries, channels and coastal sites) to integrate...

Large-scale patterns of river inputs in southwestern Europe: seasonal and interannual variations and potential eutrophication effects at the coastal zone
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Romero, Estela; Garnier, Josette; Lassaletta, Luis; Billen, Gilles; Le Gendre, Romain; Riou, Philippe; Cugier, Philippe.
We provide data on nutrient export for 28 rivers in southwestern Europe and analyze long-term changes in the context of anthropogenic pressures and regulation policies. Special attention is given to seasonal variations, because the integrated annual values that are usually provided do not allow us to establish comparisons with seasonal phytoplankton dynamics. The eutrophication risk associated with river inputs is addressed by means of an indicator (Index of Coastal Eutrophication Potential, ICEP, Billen and Garnier, Mar Chem 106:148–160, 2007). An overview of the temporal evolution and the intra-annual variability of the ICEP is discussed for specific rivers and integrated coastal regions. The annual dynamics of the eutrophication indicator is analyzed to...

The french approach to managing water resources in the mediterranean and the new European Water Framework Directive
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Henocque, Yves; Andral, Bruno.
The main content of the new European Water Framework Directive is presented. Within its river basin management approach, a special mention of coastal waters status is made. Among the issues at stake are the setting up of river basin management plans, including coastal waters, and water quality assessment system leading to an harmonized definition of quality objectives and their appropriate indicators. The Rhone-Mediterranean-Corsica Water Master Plan, launched in 1996, is considered to be well fitted to this river basin approach and the necessary tools which go with it. It shows up how a river quality assessment system (SEQ) can be adapted to the coastal waters and how it can progressively lead to an efficient set of publishable environmental and...

Autores: Oursel, B.; Garnier, C.; Zebracki, Mathilde; Durrieu, G.; Pairaud, Ivane; Omanović, D.; Cossa, Daniel; Lucas, Yves.
Trace elements and organic carbon inputs to the Mediterranean sea from an urbanized area (Marseille city) were studied and characterized during flood events. Inputs were brought to the sea by two small coastal rivers whose waters were mixed together and also with treated wastewaters (TWW) just before discharge. The monitoring of the rivers during flood events showed the high temporal dynamics of water flow, suspended particulate matter (SPM), organic carbon and trace metals concentrations, typical of small coastal Mediterranean rivers and requiring an appropriate sampling strategy. Dissolved/particulate partition coefficient (log Kd) in rivers during floods remained quasi-constant for a given trace element, but differed from one element to another...

Autores: Mathieu-resuge, Margaux; Kraffe, Edouard; Le Grand, Fabienne; Boens, Andy; Bideau, Antoine; Lluch-cota, Salvador E.; Racotta, Ilie S.; Schaal, Gauthier.
Understanding the nature and origins of food sources supporting coastal lagoon-inhabiting organisms is necessary to evaluate the ecological status of such ecosystems. The trophic ecology of a bivalve specie Spondylus crassisquama was studied in the Ojo de Liebre lagoon (Baja California, Mexico), combining stable isotope (SI), fatty acid (FA) and sterols analyses along a transect under oceanic influences. The second objective of the study was to investigate if sterols compositions give complementary information to those obtained from FA and SI. Temporal and spatial patterns of the three biomarkers in bivalve tissues suggest oceanic inputs at the mouth of the lagoon, while the inner station was characterized by a contribution of local sources including an...

Atmospherically-promoted photosynthetic activity in a well-mixed ecosystem: Significance of wet deposition events of nitrogen compounds
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Boulart, C; Flament, Pierre; Gentilhomme, V; Deboudt, K; Migon, C; Lizon, F; Schapira, M; Lefebvre, Alain.
Wet atmospheric deposition of dissolved N, P and Si species is studied in well-mixed coastal ecosystem to evaluate its potential to stimulate photosynthetic activities in nutrient-depleted conditions. Our results show that, during spring, seawater is greatly depleted in major nutrients: Dissolved Inorganic Nitrogen (DIN), Dissolved Inorganic Phosphorus (DIP) and Silicic acid (Si), in parallel with an increase of phytoplanktonic biomass. In spring (March-May) and summer (June-September), wet atmospheric deposition is the predominant source (&gt; 60%, relative to riverine contribution) for nitrates and ammonium inputs to this N-limited coastal ecosystem. During winter (October-February), riverine inputs of DIN predominate (&gt; 80%) and are annually the most...

Tanzanian Coastal and Marine Resources: Some Examples Illustrating Questions of
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Francis, J.; Bryceson, I.
The coast of Tanzania is characterised by a wide diversity of biotopes and species, typical of the tropical Indowest Pacific oceans, and the peoples living there utilise a variety of its natural resources. Because of the extent of the diversity and variety, several different examples are used by this study to elucidate the complexity of issues and multiplicity of management responses related to use of coastal and marine resources. It emerges that coastal management requires an integrated cross-sectoral approach to address the wide array of interrelated issues involved.

A coastal zone contains a range of natural envionments that man uses in different ways to provide a variety of goods and services. Some of these goods (e.g. oil and gas, fish and mangrove wood) and services (e.g. recreational values of beautiful beaches) are tangible and marketable. Other such as nutrient flows, waste reception and stabilization functions are less tangible.

The coastal zone and oceanic problems of Sub-Saharan Africa
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ibe, A.C.
The coastal zone and oceans surrounding Sub-Saharan Africa, with their vast resources of food, energy, and minerals, not only are composed of various fragile ecosystems, but are scenes of a variety of often conflicting uses. At present, the uncontrolled development of the coastal zone and ocean and the almost haphazard exploitation of their natural resources threaten to turn the promise of economic prosperity into an environmental nightmare that portends great dangers for present and future generations. There is the urgent need to put in place national management policies that address the environmental controls and procedures to be applied in pursuit of economic development. However, the oceans have no physical boundaries corresponding to national...

Dynamique sédimentaire et répartition granulométrique des sédiments de surface dans la frange littorale Ras Taguermess-Ras Marmour (golfe de Gabès)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Brahim., M.; Abdelfattah., A.
Les analyses granulométriques des sédiments superficiels de la zone côtière située entre Ras Taguermess et Ras Marmours montrent que les petits fonds (-2 à -10 m) sont couverts par des sables fins aux sables grossiers (la moyenne est entre 0,39  et 3,34 ), généralement mal à très mal classés. Cependant, le haut de plage situé entre Ras Taguermess et Ras Marmour est couvert essentiellement par des sables fins et des sables moyens (la moyenne est entre 1,082 et 2,823 ). La répartition spatiale des sables ne montre pas un grano-classement décroissant ou croissant des sédiments de la côte vers le large. Cette distribution est due à l‘existence d’une énergie importante où la houle joue le rôle essentiel sur leur répartition. L’étude granulométrique montre aussi...

As a contribution to the implementation of the National Environmental Polices for the Sustainable Development of Oceanic Spaces and Coastal and Insular Zones of Colombia, the physical characterization of the  north littoral of Cordoba department (Paso Nuevo-Cristo Rey), was undertaken. The aim of doing it, was to determine which are the causes of the erosive processes that are present and to suggest solutions that help to reduce the vulnerability of the coastal populations of the area. In this area Tertiary sediments of fluvio-marine origin, are cropping fractured, weathered and slightly folded. The geomorphological characteristics show that the fluvio-marine terraces, which are limited by cliffs of up to 15 m of height, are the most represented unit and...

Coastal Ecosystems
Provedor de dados: Ocean Docs: e-repository of  publications
The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango...

The communities do not have a compression of the environmental on the resource, as well as the fragility of the coastal ecosystems. Between the negative effects over the environmental are the indiscriminate cutting, the pollution, all of them due to the ignorance of the mangove forests benefits. The economic activities are industrialists and agriculturists where the spiny lobster fishery (P. argus) is the most important. A decrease of the level of captures from 1990 to 2003, was observed. This behavior reflects the deteriorate conditions of the environment, which limit the recruitment and affect some nursery areas, as well as the...

The eastern African coastal forest ecoregion is recognised as one of Africa’s centres of species endemism, and is distributed over six countries (Somalia, Kenya, Tanzania, Mozambique, Zimbabwe and Malawi). Most is found in Kenya, Tanzania and Mozambique, which form our focal region. The coastal forests are fragmented, small and surrounded by poor communities that have a high demand for land and forest resources. Although coastal forests have significant cultural and traditional values for local communities, they do not receive adequate support from the relevant government authorities and international conservation institutions.

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Shi, H.; Singh, A.; Foresman, T.; Fosnight, E.A.
This study focuses on assessing the state of population distribution, land cover distribution, biodiversity hotspots and protected areas in global coastal zones. The coastal zone is defined as land within 100 km of the coastline. This study attempts to answer such questions as: how crowded are the coastal zones, what is the pattern of land cover distribution in these areas, how many of these areas are designated as protected areas, and what is the state of the biodiversity hotspots. This study uses globally consistent and comprehensive geo-spatial data sets based on remote sensing and other sources. The application of modern Geographic Information System (GIS) layering methods and consistent data sets has made it possible to identify and quantify selected...

Contribution of Cameroon: An outlook of Cameroon's coastal zone
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Keumejio, E.D.
Like all coastal zones, the cameroonian coast is a complex and diversified environment, controlled by atmospherice, marine and terrestrial phenomena. This diversity is a result of natural changes, human activities, and even the diversity of resources. Coastal zone falls among the most productive ecosystems in the biosphere; they possess specific attributes from which socio-economic development can either benefit, or suffer. Thus their harmfulness is a commensurate with their potentials. In effect, these zones are often subjected to chaotic, and even destructive exploitation wich tends generally to off set the ecological equilibria.

Methodological Guide :Steps and Tools Towards Integrated Coastal Area Management
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Hénocque, Y.; Denis, J.
This second volume of a guide to integrated coastal zone management opens a new dimension by discussing the processes involved in a more complete and dynamic way than the first, To fulfil1 this requirement, an expanded work group, drawing upon the knowledge of experts in political science, economics, and sociology, devoted over two years of effort (1999 - 2001) to its completion, following a disciplined working method. A dual principle prevailed in the application of this method. On one hand, it prescribed an approach structured as a series of steps, and on the other, it demanded that real situations be brought to light, emphasizing case studies of experience with or analysis of coastal management.

Autores: Klein, R.J.
The work presented in this PhD thesis has not been carried out within a single, well-defined project. Instead, it integrates the results of a number of studies conducted from 1994 onwards, each of which had different clients and objectives. The common theme of the studies has been the description and analysis of elements that determine how coastal systems and communities would and could respond to climate change and, in particular, how this response may be assessed as part of coastal vulnerability studies. Coastal zones are amongst the most dynamic natural environments on earth, providing a range of goods and services that are essential to human social and economic well-being. Coastal zones represent the narrow transitional zone between the world’s land...

Eastern Africa Atlas of Coastal Resources: Kenya
Provedor de dados: Ocean Docs: e-repository of  publications
Marine fisheries in Kenya are based on a small number of species, the most important of which are demersal and caught by artisanal fishermen operating between the shoreline and the reef. Of the national total annual fishery production only 7.4% comes from marine waters. Freshwater fish landings in Kenya have always been higher than those from coastal waters. However, while the disparity was not too great until the mid-1970s, the difference has broadened significantly due to the marked increase in freshwater fish production since then. While freshwater fish production increased from around 22,000 tonnes in 1975 to 138,000 tonnes by 1989, marine fish landings have remained consistent between 5,000 and 8,000 tonnes over the same period.

For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns. In order to determine how the environmental factors influenced the fish community structure, the...

The northern sector of the Argentine continental shelf (34º S-41º S) is a highly productive area that sustains important fishery resources like Argentine anchovy (Engraulis anchoita) and is characterized by the presence of frontal zones with retention of detritus and plankton. In marine environments the bacterioplankton represents one of the main components of the trophic nets and plays a key role in biogeochemical cycles. In this ecosystem biomass and bacterioplankton distribution as well as their relation to environmental variables were analyzed. The highest chlorophyll a values, not significantly related to bacterioplankton (p &gt; 0.05), were found in frontal and coastal areas. Abundance, bacterial biomass and cell volume values ranged 0.48-5.42 x 106...

Coral reefs and their management in Tanzania
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Wagner, G.M.
Coral reefs are very important in Tanzania, both ecologically and socio-economically, as major fishing grounds and tourist attractions. Numerous fringing and patch reefs are located along about two-thirds of Tanzania’s coastline. These reefs have been partially to severely degraded by human (primarily destructive fishing practices) and natural (particularly coral bleaching) causes. These immediate human causes have been brought about by various socioeconomic root causes, particularly poverty and lack of proper management. After decades of human and natural impacts there has been only limited reef recovery. This paper presents a region-by-region analysis of trends in the condition of coral reefs in Tanzania in relation to the causes of damage. While earlier...

Dynamique sédimentaire et répartition granulometrique des sédiments de surface dans la frange littorale Ras Taguermess-Ras Marmour (golfe de Gabès)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Brahim., M.; Atoui, A.
Les analyses granulométriques des sédiments superficiels de la zone côtière située entre Ras Taguermess et Ras Marmours montrent que les petits fonds (-2 à -10 m) sont couverts par des sables fins aux sables grossiers (la moyenne est entre 0,39  et 3,34 ), généralement mal à très mal classés. Cependant, le haut de plage situé entre Ras Taguermess et Ras Marmour est couvert essentiellement par des sables fins et des sables moyens (la moyenne est entre 1,082 et 2,823 ). La répartition spatiale des sables ne montre pas un grano-classement décroissant ou croissant des sédiments de la côte vers le large. Cette distribution est due à l‘existence d’une énergie importante où la houle joue le rôle essentiel sur leur répartition. L’étude granulométrique montre aussi...

Impact de l'érosion côtière et éléments d'étude de vulnérabilité : example du Togo (Golfe de Guinée)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Blivi, A.B.
La morphodynamique côtière permet d'analyser les séquences de plages réflexives et dissipatrices des côtes sablonneuses. Les ouvrages maritimes perturbent le mécanisme hydro-sédimentaire et déclenchent l'érosion côtière dont les impacts de recul sont généralement assez forts, notamment de 12 m/an sur le segment de 5 km de côte, à l'est du système d'infrastructures portuaires de Cotonou, au Bénin, et de 5 à 10 m/an sur environ 30 km de côte, au Togo. Cette caractérisation morphodynamique de plage, aussi bien à court qu'à long terme, est en réponse aux variations significatives du bilan sédimentaire dont les conséquences ' sont très importantes du fait de l'utilisation de l'espace pour des activités industrielles et urbaines très variées et de la forte...

Autores: El Raey, M.; Hagenstad, M.; Smith, J.; Agrawala, S.; van Aalst, M.; Conway, D.; Moehner, A.
This report presents the integrated case study for Egypt carried out under an OECD project on Development and Climate Change. The report is structured around a three-tiered framework. First, recent climate trends and climate change scenarios for Egypt are assessed and key sectoral impacts are identified and ranked along multiple indicators to establish priorities for adaptation. Second, donor portfolios are analyzed to examine the proportion of development assistance activities affected by climate risks. A desk analysis of donor strategies and project documents as well as national plans is conducted to assess the degree of attention to climate change concerns in development planning and assistance. Third, an in-depth analysis is conducted for coastal zones...

Coastal resources and management systems influenced by conflict and migration: Mecúfi, Mozambique
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Bryceson, I.; Massinga, A.
Coastal resource utilization and management systems, bothtraditional and more recently conceived, were studied in Mecufidistrict, northern Mozambique in a post-conflict situation prior towhich a significant migration of people to the coast had occurred.A wide variety of coastal biotopes containing a multitude ofresources had been affected in various ways. Intertidalorganisms exhibited signs of decreasing abundance and averagesize, whereas offshore fishes and mangrove forests did not showsigns of overutilization. It was observed that traditional coastalmanagement systems were still influential, but that newerinitiatives were only beginning to enter into significant dialogueand cooperation with these. In the current circumstances ofpeace and political...

Provedor de dados: Boletín de Investigaciones Marinas y Costeras (INVEMAR)
Autores: Correa-Ramirez,Marco; Pacheco,Wilberto; Ricaurte-Villota,Constanza.
ABSTRACT To counteract the spread of the Covid-19 pandemic disease, the Colombian government decreed a quarantine period from March 24 to July 1, 2020, which forced the cessation of tourist activities and the closure of the main tourist destinations of the Colombian Caribbean: Santa Marta, Cartagena, and San Andrés. During this period, a significant increase in the environmental quality of these coastal zones was perceived. To quantify environmental changes in the coastal zone, the variation in chlorophyll concentration and total suspended solids observed by the Sentinel-3 satellite mission, 30 days before and after the start of the quarantine, was analyzed. The results showed a decrease in the concentration of chlorophyll (&gt; 20 %) and suspended solids...

Seasonal variability of coastal water quality in bay of Bengal and Palk Strait, Tamilnadu, Southeast Coast of India
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Srinivasan,Viswanathan; Natesan,Usha; Parthasarathy,Anitha.
The aim of this work was to study the physicochemical parameters of water quality collected from 12 sampling stations from Topputhurai to Muthupet in Vedaranyam located on the southeast coast of India from January to December 2008. Results showed that the DO and nutrients were the maximum in the Bay of Bengal during the monsoon period. High concentration of the nutrients in summer season was obtained near the Muthupet mangroves compared to the Palk Strait, which showed that this acted as a source of nutrients to the adjacent coastal waters. Low concentrations of the nutrients observed in the monsoon could be attributed to the terrestrial runoff from Muthupet lagoon. The physicochemical characteristics of coastal waters between the Point Calimere and...

Influence of effluents from a Wastewater Treatment Plant on nutrient distribution in a coastal creek from southern Brazil
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Santos,Isaac Rodrigues; Costa,Ronaldo Cataldo; Freitas,Ubiratan; Fillmann,Gilberto.
The hypothesis that effluents treated through activated sludge process cause changes in nutrient biogeochemistry of receiving water bodies was investigated in Vieira creek, southern Brazil. Dissolved oxygen, suspended matter, and pH did not vary among the sampling stations. Nutrient, biochemical oxygen demand, and conductivity values were significantly higher downstream from the Wastewater Treatment Plant (WWTP) effluents. Further downstream, nitrate concentrations were higher due to ammonium nitrification, organic matter remineralization and/or the occurrence of unidentified sources. Per capita nutrient emission factors were estimated to be 0.16 kg P.yr-1 and 4.14 kg N.yr-1. Under pristine conditions, low N:P ratios were observed, which were significantly...
