| The IOC Data and Information system will provide seamless access to the real-time and delay-mode oceanographic data and services across all IOC and related programmes, handling data from the point of collection, through processing and quality control, to archival and dissemination. The IODE developed Ocean Data Portal (ODP) will facilitate the exchange and dissemination of data and services from these systems and will be a key component to deliver the objectives of the IOC Data and Information Strategy. Data, metadata and information will be fully interoperable with the WMO Information System (WIS) and the ODP will function as a WIS Data Collection or Production Centre (DCPC) providing oceanographic data and services. |

| The IODE Quality Management Framework (IODE-QMF) provides overall strategy, advice and guidance for NODCs to design and implement quality management systems (QMS) for the successful delivery of oceanographic and related data, products and services. The IODE Committee encourages NODCs to implement a QMS but does not propose a specific standard. NODCs may seek ISO 9001 quality management certification, however this is not mandatory and NODCs can successfully implement an effective quality management system without going through formal ISO 9001 certification. |

| The Joint WMO/IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM) was formally established in 1999 by Thirteenth Congress and the Twentieth Session of the IOC Assembly, through a merger of the Commission for Marine Meteorology (CMM) and the Joint IOC/WMO Committee for IGOSS. JCOMM is the reporting and coordinating mechanism for all operational marine activities in both WMO and IOC. As such, it is charged with the international coordination, regulation and management of an integrated, operational, oceanographic observing, data management and services system which will eventually become the ocean equivalent of the World Weather Watch. Thus JCOMM is the implementation arm of GOOS. |

| Wetlands are dynamic landforms which vary in both time and space. Tanzania's wetlands areclassified according to the physiography and the environment in which they exist. Coastalwetlands, Rift System wetlands and the wetlands of highland drainage basins are the majorgroups. Coastal wetlands are formed by wave action and tidal influence; beaches and lagoons exist because of wave action; mudflats, marshes, mangrove swamps, estuaries and deltas aretidal in origin. Rift System wetlands occur in the rift depressions and are characterised by salt lakes, playas, swamps and short streams with inland drainage. The highlands are drained by long rivers originating in the inland catchments and ending in oceans or lake basins. On theway to their outlets, they form... |

| This paper examines how rural Caprivians secure their livelihoods, in order to understand how wildlife and other community based natural resource management (CBNRM) initiatives can "fit in" to current activities and the rural economy. The livelihoods and priorities of different types of households are assessed, and the many positive and negative impacts of CBNRM initiatives identified. The aim is to understand wildlife and CBNRM from householders' perspectives, and recommend how conservancies, and other natural resource management initiatives can be implemented in ways that maximise the positive impacts to rural livelihoods and minimise the negative impacts. The paper first considers the wide range of resource uses and livelihood strategies employed by... |

| St Lucia, is a large coastal lagoon, which is very sensitive to changes in water level,volume and quantities of inflowing freshwater. It is therefore sensitive to the effects of global change that alter sea levels and rainfall. Earlier studies have shown that, during the Eemian, St Lucia was a marine environment. At that time global sea level was 3-4 m higher than that at the present. During the falling sea level leading up to the Last Glacial Maximum, St Lucia was above sea level and the climate was mainly dry. Studies of cores at Brodie’s Crossing showed that there were episodes with a wet climate at 23 000 years BP. During this period peat was deposited. Overlying this is wind-blown sand. Diatom studies indicate that this overlying sand was mainly... |

| Tropical forest ecosystems have multiple functions and therefore are great significance for the well-being of people. It is widely acknowledged that forests and trees simultaneously provide a wide range of socio-economic and environmental benefits and values to humankind. They deserve conservation and wise use for the benefit of rural people who are dependent on these forests and for the benefit of humanity in general. Unfortunately, the use of tropical forests has been undertaken with little care about their potential to fulfil many functions and also about their future. |

| The nutritional effects of the complete or partial replacement of fishmeal by Soyabean meal in the diets of catfish were investigated. Four diets A, B, C, and D in which 34% of fish meal was replaced weight by weight with 0%, 10%, 20% and 34% of Soya-bean meal respectively were fed to four groups of brackish water catfish for six weeks. Results showed that although the digestibilities of proteins were almost equal in all the four groups, the groups fed diet D in which 100% of the fishmeal had been replaced by Soyabean had the least growth as compared to A, B and C. Nevertheless, the group fed diet D (with the least growth) had an economy of gain twice that of the group fed diet A. The liver and heart indices and the proximate compositions of the muscle... |

| The two most important foreign exchange earning activities in the Seychelles are tourism and fisheries and therefore, the coastal areas and their management are of the greatest importance to the Seychelles government (Khadun, 1991). In recent years government policy has encouraged marine conservation (Procter, 1970; 1984-1989 National Development Plan) and is part way to fulfilling the programme outlined in the Environmental Management Plan of the Seychelles (EMPS, 1990-2000). To date, five marine areas have been designated as national marine parks covering about 23 000 ha with several more proposed parks and protected areas. However, financial constraints, a deficit of qualified personnel, lack of boundary delimitation, inadequate legislation and... |

| Fishing plays an important role in the Senegalese economy and society. Indeed, it is a multipurpose activity that contributes towards reducing the balance of payments deficit, reducing unemployment and satisfying the protein needs of the population. Despite its importance, the fishing sector is facing serious socioeconomic disequilibria, which has lead to overfishing and the use of harmful methods of production. This, in turn, has resulted in the shortage of supplies to local markets and a reduction in protein intake for populations dependent on fishing. Furthermore, the strong tendency to export Senegalese piscatorial products has led to a shift in focus of the fishing effort from locally consumed species (pelagic) to export oriented ones (demersal),... |

| Developing capacity in coastal and marine issues of the Western Indian Ocean (WIO) region is a very important activity, given the present growing and projected pressures on the coastal and marine resources. The region’s experience in both knowledge-based, technical and equipment capacity building has been progressively growing. Many large milestones have been reached in this current effort to assess the capacity of the WIO region both in the form of increasing the knowledge base on core competencies of a good coastal manager as well as identifying the capacity-building efforts going on in the region. > Management of coastal and marine issues is critical to ensure a sustainable future in a region where tens of millions of people depend on coastal... |

| Beach nourishment is the process of dumping sand on the beach to increase the width or the height of the beach. For along time this had been the most widely used on the beach. Table shows the many beach nourishment programs that have been implemented on the beach. While beach nourishment is regarded as soft and environmentally friendly method of combating coastal erosion it is a stopgap temporary measure. It requires periodic implementation. The return period of the nourishment programs since 1982 averages two years. This option is only a stopgap measure and not permanent. Hence this option cannot be viewed as a lasting solution to the problem. |

| The seerfish group (Scomberomorus and Acanthocybium species) contributes less than 2% to the total landings from the western Indian Ocean (FAO Area 51, Fig. 1) (FAO 1994). Although its contribution is minor in quantity when compared with the landings of other major fish groups, it is considered as the prime fish in almost all the countries bordering this area. Seerfish fetch a higher price per kilogram than any other marine fin-fish landed in these countries. It is also a valuable export product in some of these countries (e.g., Oman). The high demand appears to have triggered over-exploitation of some stocks living in this region. Therefore, research studies are needed to assess these stocks to formulate appropriate management and development plans.... |
