Synopsis (short abstract) The eighteenth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Banjul, the Gambia, 26 June–1 July 2018. The first day of the meeting was dedicated to reviewing the outcomes of a two-day meeting to discuss the relevance of 2017 survey data from the R/V Dr Fridtjof Nansen to the Working Group. During the remaining days, the Group assessed the status of the small pelagic resources in Northwest Africa and made projections on the development of the status of the stocks and on future effort and catch levels. The advice for the stocks is in general given in relation to the agreed target and limit reference points (F0.1, B0.1, FMSY, and BMSY)and on the basis of the projections for the next four or five years. The structure of the report is in general the same as that of the previous Working Group reports (FAO, 2002–2017), and includes information on the small pelagic fisheries in the Canary Islands. A separate section is devoted to each of the main groups of species (sardine, sardinella, horse mackerel, chub mackerel, anchovy, and bonga). For each of these, standardized information is given on stock identity, fisheries, abundance indices, sampling intensity, biological data, assessment, projections, management recommendations and future research. Additional information on the different analysis and choices made by the Working Group has been included, when this was deemed necessary. The Working Group continued the exploration of alternative assessment methods as CMSY for poor data to be used together with the assessment methods traditionally used as well as the work on documenting options and information used in the assessment, thus following up on recommendations from a technical review and the CECAF Expert Group meeting on assessment methods (FAO, 2015) and on recommendations from the Scientific sub-committee. La dix-huitième réunion du groupe de travail de la FAO sur l'évaluation des espèces de petits pélagiques au large de l’Afrique nord-occidentale s'est tenue à Banjul, en Gambie, du 26 juin au 1er juillet 2018. Le 26 juin a été consacré à l'examen des résultats d'une réunion de deux jours tenue à l'IMR à Bergen pour discuter de la pertinence des données de la campagne de 2017 du N/R Dr Fridtjof Nansen pour le groupe de travail. M. Erling Kaare Stenevik (IMR, Norvège) a présenté le document de travail et a dirigé les discussions avec le groupe de travail. Entre le 27 juin et le 1er juillet, le Groupe a évalué l'état des ressources en petits pélagiques au large de l’Afrique nord-occidentaleet a fait des projections sur l'évolution de l'état des stocks ainsi que sur l'effort futur et les niveaux de capture. Les avis concernant les stocks sont généralement donnés par rapport aux points de référence cibles et limites convenus (F0.1, B0.1, FMSY et BMSY) et sur la base des projections pour les quatre ou cinq prochaines années. La structure du rapport est généralement la même que celle des rapports précédents du Groupe de travail (FAO, 2002-2017) mais inclue des informations supplémentaires sur les pêcheries de petits pélagiques dans les îles Canaries. Une section distincte est consacrée à chacun des principaux groupes d’espèces (sardine, sardinelles, chinchards, maquereau, anchois et bonga). Pour chacune des espèces, des informations standardisées sont fournies sur l'identité du stock, les pêcheries, les indices d'abondance, l'intensité de l'échantillonnage, les données biologiques, l'évaluation, les projections, les recommandations de gestion et les recherches futures. Des informations supplémentaires sur les différentes analyses et choix effectués par le groupe de travail ont été incluses, lorsque cela a été jugé nécessaire. Les captures totales des principales espèces de petits pélagiques dans la sous-région ont connu une augmentation minime, passant de 2,7 millions de tonnes en 2016 à 2,71 millions de tonnes en 2017. Les captures totales de petits poissons pélagiques ont fluctué entre 1990 et 2017, avec une moyenne d'environ 1,9 millions de tonnes alors que la moyenne des cinq dernières années est de 2,5 millions de tonnes. Des campagnes de prospection couvrant l'ensemble de l'aire de répartition de l'espèce ont été effectués en 2017 par le N/R Dr Fridtjof Nansen. Le groupe de travail a poursuivi l'exploration de méthodes d'évaluation alternatives comme CMSY, afin de remédier aux problèmes de données à utiliser (poor data), en plus dedes méthodes d'évaluation utiliséestraditionnellement par le groupe, ainsi que la documentation des options et des informations utilisées dans l'évaluation, suite aux recommandations issues de la réunion du groupe d’experts du COPACE sur les méthodes d’évaluation des stocks (FAO, 2015) et les recommandations du sous-comité scientifique du COPACE.

    The second meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Banjul, Republic of the Gambia, from 5 to 12 April 2002. During this year's meeting the emphasis was on updating the database as well as knowledge of assessment methods within the group. At the beginning of the meeting a two-days course in assessment methodology was held. A separate section is devoted to each of the main groups of species (sardine, sardinellas, horse mackerels a nd mackerel). For each of these, actualized information until 2001 is given on stock identity, the fisheries, catch and effort, biological data and abundance indices. A number of preliminary assessments for various species were carried out. Although the group is not yet in a position to make short/long-term projections, it is expected that the pelagic stocks will decline further in case of an expansion of the (industrial) fishing effort in the area. As a general recommendation the group therefo re suggests that the fishing effort should be restricted to the current level.

    The sixth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Banjul, Gambia, from 2 to11 May 2006. This year, the Group made decisions on reference points for management of the pelagic stocks in the region. The advice for the stocks is given in relation to these reference points and on the basis of predictions for the next five years. The results of the assessments indicate that the stock of round sardinella is overexploited and co nsequently a decrease in effort in total sardinella fishery was recommended. The Atlantic horse mackerel was found to be probably fully exploited whereas the Cunene horse mackerel was found not fully exploited. Given that this is a mixed fishery, a decrease in the catches of horse mackerel was recommended. The mackerel was found not to be fully exploited, but given the mixed fishery with other species, it was recommended that the catches should not exceed 200 000 tonnes. The sardine stock in Zone A+B was found not fully exploited and the Working Group recommended not to increase catches above the average level of the last 5 years. The stock of sardine in Zone C was found to be underexploited and it was noted that the total catch level may be progressively increased during a five-year period. It was not possible to reach reliable conclusions from the assessments for bonga and anchovy, but in the case of anchovy acoustic estimates show an increasing biomass in recen t years. For bonga the catch rates are stable. The Working Group recommended as a precautionary measure that the catch level should not exceed the average over the five and three last years, for bonga and anchovy respectively.

    A permanent FAO/CECAF Working Group composed of scientists from the coastal countries and from those countries or organizations playing an active role in demersal fisheries in Central-West Africa, was created by CECAF in 2000. The first meeting of Subgroup North was organized in Saly, Senegal, from 14 to 23 September 2004. The overall objective of the Group is to contribute to the improvement of the management of demersal resources in Northwest Africa through assessment of the state of stocks and fisheries to ensure the best sustainable use of the resources for the benefit of coastal countries. The study zone for the Working Group is the CECAF zone of the Central-East Atlantic Ocean between Cap Spartel and the south of Senegal. For reasons of heterogeneity, the species and stocks assessed by the Working Group were divided into four groups: hake, other demersal fish, shrimps and cephalopods. For each of these groups information is provided on the fisheries: sampling schemes and sampling intensity, biological characteristics, stock identity, trends (catch, effort, biological data and abundance indices), assessment, management recommendations and future research. Un Groupe de travail permanent FAO/COPACE, composé de scientifiques des États côtiers et des pays ou organisations qui jouent un rôle actif dans les pêcheries démersales de l’Afrique centre-occidentale a été créé par le COPACE en 2000. La première réunion du Sous-groupe Nord a été organisée à Saly, Sénégal, du 14 au 23 septembre 2004. L’objectif général du Groupe de travail est de contribuer à améliorer l’aménagement des ressources démersales en Afrique du Nord-Ouest par l’évaluation de l’état des stocks et des pêcheries afin d’assurer une meilleure utilisation de ces ressources pour le bénéfice des pays côtiers. La zone d’étude du Groupe de travail est la zone COPACE de l’océan Atlantique Centre-Est, entre Cap Spartel et le sud du Sénégal. En raison de l’hétérogénéité des espèces et des stocks, le Groupe de travail sur les démersaux a été divisé en quatre groupes: merlus, autres démersaux, crevettes et céphalopodes. Pour chacun de ces groupes, des informations sont données sur les pêcheries: système et intensité d’échantillonnage, caractéristiques biologiques, identité du stock, tendances (capture, effort de pêche et indices d’abondance), évaluation, recommandations d’aménagement et recherches futures.

    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.

    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.
