About twenty years ago, there was a recognition in Europe that real benefits would flow from coordinating the manner in which food composition tables were produced in the various countries of Europe. Subsequent development of computerised nutritional data bases has further highlighted the potential advantages of working together. Such cooperation could lead to improved quality and compatibility of the various European nutrient data bases and the values within them. This realisation was one of the driving forces behind the development of the Eurofoods initiative in the 1980's when those people in Europe interested in data on food composition began working together. This initiative received further impetus with the establishment of the Eurofoods-Enfant Concerted Action Project within the framework of the FLAIR (Food-Linked Agro-Industrial Research) Programme of the Commission of the European Communities. It was quickly recognised that the draft guidelines for the production, management and use of food composition data which had been prepared under the aegis of INFOODS (International Network of Food Data Systems, a project of the United Nations University), would be especially applicable to the objectives of the Concerted Action. The guidelines have been written by two recognised experts. Many people associated with FLAIR Eurofoods-Enfant have added constructive criticism and advice to that offered previously by those associated with INFOODS. Thus the guidelines are backed by a consensus in the community of those responsible for the production and use of food composition tables and nutrient data bases.

In its thirtieth session the Commission reviewed the intersessional activities of its Scientific Advisory Committee (SAC) and its Committee on Aquaculture (CAQ). Based on the advice emanating from SAC and proposals by Members, the GFCM adopted respectively: three binding recommendations on fisheries management measures, including on fishing effort and on the protection of sensitive habitats; two recommendations on illegal, unreported and unregulated (IUU) fishing, including on the establishment of a black list of vessels and on data confidentiality procedure. It also endorsed three recommendations from the International Commission for the Conservation of Atlantic Tunas (ICCAT), including on the establishment of a programme for transshipment by large-scale longliners. The GFCM reiterated its satisfaction with progress made in the implementation of the five regional projects executed by FAO in support of the Commission. The Commission ascertained its financial situation and agreed to use arrears to build a Working Capital Fund. In the Secretariat, it established a post of Statistician and a post of Programmer/System Analyst. Work progress related to the new headquarters of the Commission was reviewed. The Commission decided to postpone the adjustments to its Rules of Procedure to its next plenary. The Commission established a Compliance Committee. It formalized the Environment Aquaculture Mediterranean Network (EAM) and the Statistical Information System on Aquaculture (SIPAM) as subsidiary bodies of CAQ, and endorsed the guidelines prepared by the Joint GFCM/ICCAT Working Group on Sustainable Tuna Farming. The Commission agreed on its programme of work and adopted its autonomous budget for the year 2006. The GFCM elected its new Bureau

La biodiversité calédonienne, reconnue comme l’une des plus exceptionnelles avec son fort taux d’endémisme, est largement menacée par l’introduction de nouvelles espèces. Il est donc important de protéger l’écosystème calédonien, à la fois riche et vulnérable, des espèces envahissantes, l’une des principales causes de perte de la biodiversité à l’échelle mondiale. Face à cette menace, le Gouvernement et les trois provinces de Nouvelle-Calédonie souhaitent mettre en place une structure collective afin de définir les orientations stratégiques nécessaires pour préserver et conserver leur biodiversité. Elles ont ainsi voulu qu’un état des connaissances soit dressé et qu’une réflexion soit menée sur la prévention, la détection précoce, l’intervention rapide, l’éradication, le confinement et le contrôle des espèces envahissantes. Cette expertise collégiale apporte les éléments nécessaires à la construction d’un système de biosécurité pertinent et efficace pour l’archipel néo-calédonien.

The 2020 edition of the WWDR, titled 'Water and Climate Change' illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses - in terms of adaptation, mitigation and improved resilience - that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.

The seemingly inexhaustible oceans have proved to be finite after all. Capture of wild fish have leveled off since the mid-1980s, and many stocks of fish are fished so heavily that their future is threatened. And yet the world's appetite for fish has continued to increase, particularly as urban populations and incomes grow in developing countries. Aquaculture--fish farming--has arrived to meet this increased demand. Production of fish from aquaculture has exploded in the past 20 years and continues to expand around the world. But will aquaculture be sufficient to provide affordable fish to the world over the next 20 years? And what environmental and poverty problems will aquaculture face as it expands? Using a state-of-the-art computer model of global supply and demand for food and feed commodities, this book projects the likely changes in the fisheries sector over the next two decades. As prices for most food commodities fall, fish prices are expected to rise, reflecting demand for fish that outpaces the ability of the world to supply it. The model shows that developing countries will consume and produce a much greater share of the world's fish in the future, and trade in fisheries commodities will also increase. The authors show the causes and implications of these and other changes, and argue for specific actions and policies that can improve outcomes for the poor and for the environment.

With by-catch in fisheries becoming an ever more high-profile problem, this brilliant work could not be more timely. It contains contributions from the world’s leading experts in by-catch reduction, who guide the reader through most aspects of the field. They examine the methodologies used to develop by-catch reduction techniques and provide new avenues for broadening such work. Case studies are provided that encompass most of the world’s fishing techniques and regions.
