Le présent document résume les conclusions du Groupe de travail CPCA sur la pollution et les pêches. Il contient des recommandations concernant les stratégies de lutte contre la pollution aquatique, notamment l'établissement de normes de qualité de l'environnement, en insistant sur l'utilisation de méthodes d'évaluation des risques pour définir des mesures de protection de l'environnement applicables à des sites particuliers. Le document examine en outre l'état du milieu aquatique africain du po int de vue de la pollution par les charges organiques, les métaux lourds et les substances organo-chlorées. Il se termine par la conclusion que, à l'exception de quelques sites critiques, la contamination des eaux intérieures de l'Afrique est encore relativement modérée. Néanmoins, la pollution par la matière organique, entraînant l'eutrophisation et l'anoxie, a été identifiée comme une des principales menaces qui pèsent sur les pêches. Bien que la contamination par les métaux et les substances organo-chlorées soit encore faible, il est impératif, compte tenu de la prévisible intensification de l'urbanisation et des activités socio-économiques, d'identifier sa provenance et de quantifier les volumes de les matières déversés dans le milieu aquatique. La présence de micro-polluants synthétiques, comme les substances organo-chlorées, dans différents compartiments du milieu aquatique, même à l'état de traces et d'ultra-traces, est un motif de préoccupation pour l'écologie et la santé de l' environnement. Tous les pays devraient formuler des stratégies de lutte contre la pollution, couvrant les questions de législation, normes et critères concernant l'environnement, minimisation des déchets, traitement des effluents, suivi de la pollution, formation, éducation et campagnes de sensibilisation du public. -

Book (series)Technical studyLatin America and the Caribbean - Regional Overview of Food Security and Nutrition 2023
Statistics and trends
2023Also available in:
The 2023 edition of the Regional Overview of Food Security and Nutrition in Latin America and the Caribbean presents an update of the data and trends in food security and nutrition in recent years. The impact of the COVID-19 pandemic, the climate crisis and the conflict in Ukraine, as well as the economic slowdown, rising food inflation and income inequality have had an impact on regional figures. The most recent data shows that, between 2021 and 2022, progress was made in reducing hunger and food insecurity in Latin America and the Caribbean. However, the progress achieved is far from the targets established to meet SDG 2 of ending hunger. In addition, one in five people in the region cannot access a healthy diet and malnutrition in all its forms, including child stunting, micronutrient deficiencies and obesity continue to be a major challenge. -

Moving forward on food loss and waste reduction
2019The need to reduce food loss and waste is firmly embedded in the 2030 Agenda for Sustainable Development. Food loss and waste reduction is considered important for improving food security and nutrition, promoting environmental sustainability and lowering production costs. However, efforts to reduce food loss and waste will only be effective if informed by a solid understanding of the problem. This report provides new estimates of the percentage of the world’s food lost from production up to the retail level. The report also finds a vast diversity in existing estimates of losses, even for the same commodities and for the same stages in the supply chain. Clearly identifying and understanding critical loss points in specific supply chains – where considerable potential exists for reducing food losses – is crucial to deciding on appropriate measures. The report provides some guiding principles for interventions based on the objectives being pursued through food loss and waste reductions, be they in improved economic efficiency, food security and nutrition, or environmental sustainability. -
