    Illegal, unreported and unregulated (IUU) fishing indicators apply readily available data and straightforward calculations to measure something that provides insight into – but does not actually estimate – the level of IUU fishing. In doing so, indicators aim to evaluate and monitor performance in combating IUU fishing, including highlighting where improvements in monitoring, control and surveillance (MCS) systems are needed. Since they are easy to update and track over time, indicators offer an alternative to often resource-intensive quantitative IUU fishing estimation methods, and can be adapted across a broad range of fisheries. This document reviews various types of indicators and develops a universal framework based on detection, coverage and investment indicators for IUU fishing. It then presents four hypothetical case studies, illustrating how these indicators can be applied to different fisheries with different IUU fishing risks. Guidance is provided for customizing indicators to individual fisheries and for interpreting various combinations of indicators moving in different directions. However, IUU fishing problems can have multiple drivers, take various forms and produce mixed signals, making it difficult to provide interpretive guidance that is appropriate for all situations. For this reason, a variety of recommendations are presented for engaging stakeholders and drawing inferences from similar fisheries.

    Applying the principles and approaches from Volume 1 of this series, this practical guide details the steps necessary to plan, execute and present estimates of illegal, unreported and unregulated fishing. For the initial planning phase, the guide provides information on how to work with stakeholders to define objectives, examine and catalogue available data, and then match the objectives with the available data to determine the most useful estimation methods. Also discussed are subsequent steps involving designing a conceptual model, triangulating alternative approaches, dealing with data gaps and biases, and accounting for uncertainty. For the execution phase, guidance is provided for developing and running models, including checking preliminary outputs with stakeholders and experts, before refining and finalizing results. Guidance for the final presentation phase focuses on how to ensure the methodology, data inputs and gaps, and assumptions are clearly explained. As in the first two phases, allowing for feedback from stakeholders on the study results, and refining the outputs as necessary, will strengthen both the quality of the work and its uptake by decision-makers.

    1. Methodologies and indicators for the estimation of the magnitude and impact of illegal, unreported and unregulated fishing: 1.1 Principles and approaches
    2023
    The Food and Agriculture Organization of the United Nations (FAO) can play an important role in encouraging consistent and sound practices for estimating illegal, unreported and unregulated (IUU) fishing activities around the world. This first volume in a series of guidance documents on this topic outlines guiding principles and approaches applicable to a broad range of IUU fishing estimation scenarios. It begins by defining which components of IUU fishing to estimate depending on the specific objectives of the exercise. It then helps to set boundaries for the estimation exercise based on the fishery, species, area and timeframe of interest. Top-down and bottom-up methodological approaches are introduced, with examples, as ways of partitioning an overall IUU fishing amount into component activities, or compiling estimates of IUU fishing at a granular scale to form an overall composite figure, respectively. Ideas for presenting results to maximize the uptake by stakeholders and decision-makers are also presented.

    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.
