Coastal zone management in Egypt

This paper introduces the institutions, rules and regulations, which have been established by the relevant Egyptian laws for addressing various coastal and sea management issue. The existing legislation shows clearly the sectoral character of the present system, suffering from insufficient communication and cooperation among different state agencies on the one hand, and among central government and municipalities on the other. There is a significant interest in Egypt for improving the coastal zone management (CZM) practices and for integration of the management from many state agencies.

Promoting cross-cultural exchanges in ICM and fisheries: The Consortium for Transatlantic Cooperation in Marine Policy and Coastal Management Education

Since 1997, institutions on both sides of the Atlantic have been building linkages under a joint US/European effort aimed at the next generation of marine policy and ocean management professionals. The Consortium for Transatlantic Cooperation in Marine Policy and Coastal Management Education is facilitating the exchange of knowledge between the United States and Europe regarding integrated coastal management (ICM) and regional fisheries management by creating course modules and case studies, conducting short intensive cross-cultural courses, offering transatlantic internship and academic exchange opportunities, and implementing distance learning technologies. The Consortium includes three European and three US universities, plus five partners from government, non-governmental organizations, and the private sector. The Consortium's ultimate goal is to foster cross-cultural understanding of ICM as it is implemented in response to international mandates such as Agenda 21, the Framework Convention on Climate Change, the Convention on Biological Diversity, and the Global Programme of Action on the Protection of the Marine Environment from Land-Based Activities. This article describes the workings of the Consortium over the past two years.     

A proposal for boundary delimitation for integrated coastal zone management initiatives

ICZM relies heavily on the definition of major multidisciplinary characteristics/elements of the coastal area of interest. Usually, only terrestrial boundaries are considered, which tend to respond to a specific sectoral problem and can be determined by administrative limits. In this study, we propose a method for establishing a decision-making tool to inform boundary delimitation for ICZM initiatives that is proactive and widely applicable as opposed to reactive and problem specific. This method integrates environmental, economic and societal characteristics of the marine and terrestrial boundaries of the coastal zone, starting at the boundary of the jurisdictional zone of influence (shoreline units), increasing in detail through the definition of their influential areas from jurisdictional, environmental or socio-economic perspectives (functional areas) and, within them, specifying the finest scale at which relevant indicator data may be obtained (analysis units).     

Coastal and fisheries co-management in South Africa: an overview and analysis

The newly elected democratic government of South Africa, has promulgated new policies and legislation which advocate alternative approaches to resource management which involve user groups. Co-management has been identified as one such strategy. An overview and analysis of selected coastal and fisheries co-management case studies in South Africa is given and key lessons are highlighted. Research findings indicate that co-management in South Africa is still in its infancy, making it difficult to provide conclusive statements about its success or failure. Nevertheless, the paper highlights some of the key conditions that are required for co-management to operate effectively in South Africa and some of the existing obstacles to practical implementation.     

Coastal issues and conflicts in North West Europe: A comparative analysis

This paper identifies and examines current coastal issues and conflicts in the northwest Europe region through the use of questionnaire surveys. The overall management concerns and outstanding problems across the region are highlighted and the results are presented in relation to previously identified management issues in northeast England, east Grampian in Scotland, and France. The survey presents a list of identified issues, each of which has a direct relationship to one of the 3 pillars of sustainable development, (environment, economic and social), and therefore the Lisbon Agenda (economic and social) and the Gothenburg Agenda (environment and environmental risk). The survey reveals that the important coastal management issues across the region are the large-scale concerns traditionally associated with ICZM: land-use planning, estuary management, natural resource and landscape protection, and water quality. Generally, respondents considered that management response to these issues is poor. Dissatisfaction levels were particularly high in France and Ireland, and to a lesser extent, in England. Water quality management escapes general criticism. This can be regarded as a positive finding, because it indicates that pan-European initiatives (the water-related EU directives) can deal effectively with this pan-European problem. The paper considers the links between the main issues across North West Europe and aims to distinguish how current coastal management practices have affected the range of issues arising.     

Three-dimensional circulation in the NW Africa coastal transition zone

High-resolution data collected southeast of the Canary Islands during late winter 2006 are analyzed to describe the hydrography and three-dimensional circulation in the coastal transition zone off NW Africa. The data are optimally interpolated over a regular grid, the geostrophic velocity field is calculated and the Q-vector formulation of the omega equation is used to compute the quasi-geostrophic (QG) mesoscale vertical velocity. The coastal transition zone is divided into upwelling, frontal and offshore regions with distinct physical and dynamic characteristics. The upwelling region is characterized by cold and weakly stratified waters flowing towards the equator, with a poleward undercurrent of approximately 0.05 m s⁻¹ over the continental slope. The frontal region exhibits a southwestward baroclinic jet associated with cross-shore raising isopycnals; the jet transport is close to 1 Sv, with maximum velocities of 0.18 m s⁻¹ at surface decreasing to 0.05 m s⁻¹ at 300 db. Vertical sections across the frontal region show the presence of deep eddies probably generated by the topographic blocking of the islands to the southward current, as well as much shallower eddies that likely have arisen as instabilities of the baroclinic upwelling jet. The QG mesoscale vertical velocity field is patchy, estimated to range from −18 to 12 m day⁻¹, with the largest absolute values corresponding to an anticyclonic eddy located south of Fuerteventura Island. These values are significantly larger than estimates for other vertical velocities: diapycnal vertical velocities associated with mixing in the frontal region (a few meters per day), and wind-induced vertical velocities (non-linear Ekman pumping arising from the interaction between the wind stress and the background vorticity, maximum values of a few meters per day; linear Ekman pumping due to the divergence of Ekman transport, a fraction of a meter per day; or the coastal constraint in the upwelling region, about 0.7 m day⁻¹). However, the patchiness in both the QG mesoscale vertical velocity and the non-linear Ekman pumping velocity cause their integrated vertical transports to be one order of magnitude smaller than either coastal Ekman transport (0.08 Sv), integrated linear Ekman pumping (−0.05 Sv) or diapycnal transfer (about 0.1–0.2 Sv). The pattern of the near-surface fluorescence field is a good indicator of these different contributions, with large homogeneous values in the coastal upwelling region and a patchy structure associated with the offshore mesoscale structures.     

Coastal zone management focusing on coastal tourism in a transitional period of China

Coastal zone management in China has undergone a developmental leap since 1978, a turning point in the country's economic and institutional reform. In examining China's reform in coastal management, this paper assesses the evolution of marine activities including coastal tourism. It also looks into the present issues of coastal resource uses and how administrative agencies responded to those coastal resource issues especially as the country moves from a planned economy to a market economy, and from centralized governance to decentralized governance. This paper also proposes a management approach for coastal tourism management in the future of China.     

Coastal oceanic climate change and variability from 1982 to 2009 around South Africa

Changes and fluctuations in sea surface temperature (SST) around the South African coast are analysed at a monthly scale from 1982 to 2009. There is a statistically significant negative trend of up to 0.5 °C per decade in the southern Benguela from January to August, and a cooling trend of lesser magnitude along the South Coast and in the Port Elizabeth/Port Alfred region from May to August. The cooling is due to an increase in upwelling-favourable south-easterly and easterly winds. There is a positive trend in SST of up to 0.55 °C per decade in most parts of the Agulhas Current system during all months of the year, except for KwaZulu-Natal where warming is in summer. The warming was attributed to an intensification of the Agulhas Current in response to a poleward shift of westerly winds and an increase in trade winds in the South Indian Ocean at relevant latitudes. This intensification of the Agulhas Current could also have contributed to the coastal cooling in the Port Alfred dynamic upwelling region. The El Niño Southern Oscillation (ENSO) is significantly positively correlated at a 95% level with the southern Benguela and South Coast from February to May, and negatively correlated with the Agulhas Current system south of 36° S. The correlation with the Antarctic Annular Oscillation is weaker and less coherent. El Niño suppresses upwelling along the coast, whereas La Niña increases it. Although there does not seem to be a linear relationship between the strength of the ENSO and the magnitude of coastal SST perturbation, El Niño and La Niña appear to be linked to major warm and cool events, respectively, at a seasonal scale in summer in the southern Benguela and along the South Coast. However, care must be taken in interpreting low-resolution reanalysed climate data (ERA40 and NCEP) and optimally interpolated Reynolds SST, such as used here.     

Advancing knowledge: a key element of the World Bank's integrated coastal management strategic agenda in Sub-Saharan Africa

Advancing knowledge in integrated coastal management (ICM) is a key element of the ICM Strategic Agenda of the World Bank in Sub-Saharan Africa (SSA). Advancing knowledge encompasses both the transfer of information and skills as well as the sharing of information and synthesis of local knowledge to support decision-making processes in client countries. Facilitating access to knowledge, generating new information and knowledge are key to empowerment. A key goal of development is empowering people to manage their own destinies. The World Bank is committed to this goal and makes concerted efforts to make information accessible and to promote knowledge in a variety of disciplines through a mix of modalities. The aim of this paper is to discuss select interventions supported by the Bank to promote ICM in SSA, the context within which they are implemented and emerging lessons from the experience.

Coastal typology: An integrative “neutral” technique for coastal zone characterization and analysis

Typology, the ‘study or systematic classification of types that have characteristics or traits in common’, has become a commonly used term and technique in coastal zone studies over the past two decades. At least part of this is due to adoption by the first Land–Ocean Interactions in the Coastal Zone (LOICZ) project of a typological approach as a way to understand and organize the daunting diversity of natural and human systems comprising the world coastal zone, and to the concurrent development of tools and databases to support systematic applications. This paper reviews some of the history of the term ‘typology’ and the concepts and techniques that it subsumes, and discusses its adoption and adaptation in coastal studies. It also addresses the continued and increasing relevance of typology to the continuation of the LOICZ project and its objectives, and outlines the opportunities and challenges involved in realizing the potentials of the approach – both within LOICZ and for the scientific and coastal zone communities in general.     

The Larval Fish Assemblage in Nearshore Coastal Waters off the St Lucia Estuary, South Africa

This paper reports on the composition, abundance and distribution of the larval fish assemblage in the nearshore coastal waters off the St Lucia Estuary mouth, South Africa. Ichthyoplankton samples were collected over a 12 month period from five stations located along a transect up to 2·5 km offshore, and from two stations north and south of the estuary mouth, respectively. In all, 6126 fish larvae, representing 89 families and 186 species, were collected. Larvae in the families Myctophidae and Tripterygiidae comprised 21% and 16% of the total catch, respectively. The most abundant species were an unidentified triplefin, Tripterygiid 1 and the lanternfish Benthosema fibulatum, together which contributed nearly 18% of the total catch. Larvae of marine spawners independent of estuaries dominated the catch both in terms of density (90%) and in terms of number of taxa (89%). Some larvae of estuarine-associated species were present, in addition to a few specimens of estuarine resident species. Overall the dominant environmental variable affecting larval densities was temperature, particularly for Trypterygiid 1 where temperature contributed to 9% of the variance model. Densities of fish larvae peaked in November and December 1990 (late spring and early summer) and were lowest from January to June 1991 (summer, autumn an early winter). Different taxa dominated the catch each month with reef- and shelf-associated species accounting for the peak in August and September 1990, oceanic species in November 1990 and a mixture of the two groups in December. Overall larval densities were significantly higher in bottom samples with a trend of increasing densities offshore for reef and shelf taxa. The larvae of reef and shore taxa were predominantly preflexion larvae, whilst the few estuarine spawner species that were collected were mainly postflexion. Ontogenetic patterns related to depth and distance offshore were evident for the dominant species in each estuarine-association category.The present study has shown that temporal and spatial variations in the larval fish assemblage off St Lucia are related to environmental conditions and ontogenetic behavioural patterns of certain species. The origin of many of the larvae in the assemblages off the coast of St Lucia is probably from both local spawning populations in the shelf waters off KwaZulu-Natal and spawning populations farther north in shelf waters off Mozambique. Additional studies with more detailed oceanographic measurements will further our understanding of the physical processes that supply larvae to the St Lucia region.
