Renewable natural resources (RNR) are a major source of socio-economic development potential in all developing countries, if they can be conserved, developed and sustainably exploited. For strategic conservation and sustainable exploitation strategies to be implemented, a knowledge of biodiversity at various levels within these RNR has to be investigated and documented in an internationally accepted manner, and preferably as close as possible to the habitat of the resources. However, human and material resources available in developing countries are currently neither sufficiently trained nor sufficient to undertake the appropriate studies. Meanwhile, various forces continue to deplete RNR and their inherent biodiversity. An attractive approach towards... |

The effects of human trampling on the population parameters of the soldier crab Dotilla fenestrata at Praia da Costa do Sol, Maputo were studied in two areas subjected to two different levels of human disturbance: (1) a low disturbance area; and (2) a high disturbance area. Sampling was carried out 1 day before and 1 day after disturbance took place and crab abundance and biomass data were compared between the two periods at each area. No significant differences (P > 0.05) were found between abundance and biomass values before and after the disturbance. These results suggest that human trampling has an insignificant effect on D. fenestrata and that behavioral and habitat structure aspects might play more important roles on the population ecology of the... |

Coral and rocky reefs are very important ecosystems in terms of their diversity, productivity, abundance and beauty. Mozambique possesses extensive reef areas, where fish fauna is the main exploited resource. Nevertheless, the ecology of these resources is little studied. A recent report listed 794 reef-associated fishes known to occur in Mozambican coral and rocky reefs. This is a first accountancy of the high fish diversity of Mozambican reefs, which must be assessed. Reef-associated fish resources exploitation is conducted at three basic levels: (i) subsistence (artisanal fishery); (ii) commercial exploitation (semi-industrial reef fishery, ornamental fish trade and recreational diving); and (iii) sports fishing. Presently, the artisanal fishery is the... |

This document describes the vision, structure and partnerships for an international information system on the occurrence, impacts, identification, and monitoring of marine and brackish water planktonic and benthic microalgae perceived as harmful by humans. The document was developed by the Joint IPHAB/IODE (Document IOC/IPHAB-VIII/3 see http://www.ioc-unesco.org/hab) Task Team on the Development of the Harmful Algal Information System (HAIS) at a Workshop 8-9 January 2008, Oostende, Belgium. The vision is an easy-to-navigate, dynamic, integrated, and distributed system with: visual and interactive quality-assured data and scientific information on harmful algae provided by experts, coupled with general information on authorities and institutions involved... |

The Integrated Global Observing Strategy Partnership (IGOS-P) established, in 1999, a thematic approach to the implementation of the IGOS. Recognising that other themes will emerge, the “Ocean Theme” was chosen to be the “pathfinder” in this approach and an Ocean Theme Team was assembled to formulate guidance. One goal of the Ocean Theme Team is to consider and study the full range of current and planned observations, while identifying potential gaps in future observations that might compromise ocean observational records. This document presents a proposed set of long-term ocean observations and identifies a number of challenges for the improvement of knowledge about both the oceans and observing techniques. The overall strategy is to create an observing... |

Argo is the most visible and innovative new element of the sustained observing system for the open ocean. Since mid-2004 it has become the most abundant source of profile data from the ocean and that abundance will continue to increase as the array grows to its target of 3000 floats that will deliver 100,000 CTD profiles per year by 2007. Paradoxically, the existence of Argo has highlighted the importance of research ship-based CTD observations. Argo floats are expendable, consequently there is no opportunity to do laboratory calibrations to check sensor drift. A method has been devised to estimate sensor drift by making comparisons with nearby (in space and time) CTD profiles collected by research ships and by comparing new and old floats. This method is... |

In 1997, IUCN-The World Conservation Union, with the financial support of the German Federal Ministry for Economic Co-operation and Development, initiated a project to examine the relationship between the Convention on Biological Diversity (CBD) and the rules of international trade–those administered by the World Trade Organisation (WTO), in particular. The project was motivated by a widely shared concern that the aims of the CBD, which are essentially to conserve and equitably distribute the benefits of the environment, might be undermined by the WTO, which aims at the liberalisation of trade. Liberalised trade has the potential to integrate economies, regionally and globally, in mutually beneficial ways. But some observers are concerned that it may do so... |

A fishery resource profile for Moree has been developed to help in exploring linkages between migration dynamics and the organisation and management of fishery activities in the study community. The biophysical study component of the Small Scale Fisheries in Africa project involves the following: (a) an assessment of the quality and quantity of fish and marine resources available to the community including best estimates of current fish stocks and natural patterns affecting their availability, (b) a review of the main types of fishing technologies used to exploit fish stocks in the community, (c) any significant qualitative and quantitative changes in fish stocks which have been documented in recent years, and (d) an assessment of the main biological and... |

Like people in many nations, South Africans value their coastal resources and are striving to manage them more effectively (Cicin-Sain & Knecht 1998; CMPP 1998, 2000; Glavovic 2000 a, b, c; Glavovic et al. 2001). The White Paper for Sustainable Coastal Development in South Africa aims to promote sustainable coastal development through integrated coastal management. This new policy represents a marked shift from earlier views of the coast and how it should be managed. What was, until relatively recently, a predominantly biophysical and bureaucratic view has been transformed into a participatory approach driven by human development imperatives and the need to promote sustainable livelihoods. How did this transformation take place, and what lessons might... |
