Book (stand-alone)Technical reportBrief on Fisheries, Aquaculture and Climate Change in the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) 2016
Also available in:
No results found.This brief synthesizes the Intergovernmental Panel on Climate Change Fifth Assessment Report’s (AR5) important knowledge on how climate change is already manifesting itself through the aquatic systems, what the future changes may be and their predicted impacts on food and livelihood security, marine and inland fisheries and aquaculture systems, and overviews AR5’s information on implications of climate change and variability for capture fisheries, aquaculture and dependent communities in eight r egions: Africa, Asia, Australasia, Central and South America, Europe, North America, Small Island States and Polar Regions. In this context, adaptation options suggested by the AR5 will be outlined for each. It concludes with a review of knowledge gaps from the fisheries and aquaculture perspective that could benefit from further IPCC efforts. -
Brochure, flyer, fact-sheetBrochureImpacts of climate change on fisheries and aquaculture 2018
Also available in:
No results found.The leaflet presents the overall content of a technical paper on current scientific knowledge available on climate change implications for fisheries and aquaculture, as well as adpatation and mitigation responses. The leaflet is meant to announce the release of the technical paper. It is prepared on the occasion of an international symposium on climate change impacts on the world's oceans with the purpose to raise interest of the participants in the symposium. However, it can be used as a 2-page communication product on any international event where FAO publications are presented. -
Book (stand-alone)Technical studyImpacts of climate change on fisheries and aquaculture
Synthesis of current knowledge, adaptation and mitigation options
2018Also available in:
No results found.The 2015 Paris Climate Agreement recognizes the need for effective and progressive responses to the urgent threat of climate change, through mitigation and adaptation measures, while taking into account the particular vulnerabilities of food production systems. The inclusion of adaptation measures in the fisheries and aquaculture sector is currently hampered by a widespread lack of targeted analyses of the sector’s vulnerabilities to climate change and associated risks, as well as the opportunities and responses available. This report provides the most up-to-date information on the disaggregated impacts of climate change for marine and inland fisheries, and aquaculture, in the context of poverty alleviation and the differential dependency of countries on fish and fishery resources. The work is based on model projections, data analyses, as well as national, regional and basin-scale expert assessments. The results indicate that climate change will lead to significant changes in the availability and trade of fish products, with potentially important geopolitical and economic consequences, especially for those countries most dependent on the sector.

Book (series)Technical studyManual de evaluación de recursos pesqueros 2002
Also available in:
El manual se presenta en el mismo orden seguido en el último curso impartido en el IPIMAR (noviembre/diciembre 1997). Se inicia con una introducción a los modelos matemáticos aplicados a la evaluación de los recursos pesqueros y con consideraciones relativas a la relevancia de la actividad pesquera. A continuación, se pone en evidencia la necesidad de una gestión racional de los recursos pesqueros, indispensable para una explotación adecuada que garantice su conservación. Se presentan las hipóte sis subyacentes de los modelos y los conceptos de las diferentes tasas de variación de los parámetro en función del tiempo (o de otros parámetros), destacando los aspectos más importantes de los modelos lineal simple y exponencial que serán ampliamente utilizados en capítulos sucesivos. A partir de algunas consideraciones sobre el concepto de cohorte, se desarrollan modelos para la evaluación en el tiempo del número y del peso de los individuos que componen una cohorte, incluyendo modelos para el crecimiento individual de la cohorte. En el capítulo sobre el estudio del stock se define el patrón de explotación y sus componentes, presentándose los modelos más usados para la relación stock-reclutamiento, ya sea como proyecciones de un stock a corto como a largo plazo. En lo que respecta a la gestión de los recursos pesqueros, se discuten los puntos de referencia biológica (puntos objetivo, puntos límite y puntos de precaución) y las medidas de regulación de las pesquerías. El último capí tulo de presentación y discusión de los modelos teóricos de evaluación de recursos pesqueros, trata de los modelos de producción (también llamados modelos de producción general) y de las proyecciones de captura y biomasa a largo y corto plazo. Finalmente se describen los métodos generales de estimación de parámetros y se presentan algunos métodos de estimación de los parámetros más importantes, con particular atención a los análisis de cohortes con edades y con tallas....... -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -
BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.
