    Bayesian approaches to stock assessment provide a means for the analyst to combine information for the stock for which an assessment is needed, information based on expert opinion, and inferences for other species in a probabilistic framework. It is even possible to consider uncertainty about which model of the population dynamics is correct. This manual provides an overview of the application of Bayesian methods through a series of worked examples in EXCEL. The examples are based on biomass dyn amics and stock-recruitment models, and focus on the use of assessments that form the basis for evaluating the consequences of alternative management actions.Also available in HTM format: http://www.fao.org/3/Y1958E/Y1958E00.htm

    Review of stock assessment data and methods in the Fishery Committee for the Eastern Central Atlantic area
    Gap analysis and proposal of new approaches

    This review summarizes the data and methodological gaps identified through the reports of the FAO working groups in the Fishery Committee for the Eastern Central Atlantic (CECAF) area. It highlights the need to improve data quality and assessment approaches appropriate to the existing data in the CECAF region. Improving data and access to existing data is a priority for the development and application of more advanced stock assessment models to strengthen the scientific advice provided and to support the CECAF Scientific Sub-Committee and the Committee.

    Emissions due to agriculture
    Global, regional and country trends 2000–2018

    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.

    FAO Strategy on Climate Change 2022–2031 2022
    The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.
