Book (series)Technical report水产养殖认证准则 2011
Also available in:
全球水产养殖生产大幅增长，为人类消费提供了数量越来越多的鱼类和其他水产品，预测这一趋势仍将继续下去。虽然水产养殖发展仍有潜力满足不断增长的水产品需求并对粮食安全、减贫和更广泛意义上实现可持续发展和千年发展目标做出贡献；但人们也愈发认识到，要实现这一潜力还需要提高该产业的管理水平。目前，应用水产养殖认证被视为一个以市场为依托的可行手段，能够在水产养殖生产和销售环节最大限度地降低潜在负面影响并增加社会和消费者的收益和信心。本准则旨在为制定、组织和实施有效的水产养殖认证方案提供指导。 -

Book (series)Technical studyThe impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
Background paper for The State of Food Security and Nutrition in the World 2018
2020Also available in:
No results found.Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated. -
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. -
Book (series)FlagshipThe State of Food and Agriculture 2019
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.
