ArticleJournal articleGenetic investigation of population structure in Atlantic chub mackerel, Scomber colias Gmelin, 1789 along the West African coast 2024
Also available in:
No results found.Sustainable management of transboundary fish stocks hinges on accurate delineation of population structure. Genetic analysis offers a powerful tool to identify potential subpopulations within a seemingly homogenous stock, facilitating the development of effective, coordinated management strategies across international borders. Along the West African coast, the Atlantic chub mackerel (Scomber colias) is a commercially important and ecologically significant species, yet little is known about its genetic population structure and connectivity. Currently, the stock is managed as a single unit in West African waters despite new research suggesting morphological and adaptive differences. Here, eight microsatellite loci were genotyped on 1,169 individuals distributed across 33 sampling sites from Morocco (27.39 N) to Namibia (22.21 S). Bayesian clustering analysis depicts one homogeneous population across the studied area with null overall differentiation (FST = 0.0001ns), which suggests panmixia and aligns with the migratory potential of this species. This finding has significant implications for the effective conservation and management of S. colias within a wide scope of its distribution across West African waters from the South of Morocco to the North-Centre of Namibia and underscores the need for increased regional cooperation in fisheries management and conservation. -
ProjectProgramme / project reportReport of the technical meeting on the lessepsian migration and its impact on Eastern Mediterranean fishery
Nicosia, Cyprus, 7 - 9 December 2010
2010Also available in:
No results found.The sub-regional technical meeting on the lessepsian migration and its impact on Eastern Mediterranean fisheries was held in Nicosia, Cyprus from the 7 th to 9 th of December 2010. Experts from Cyprus, Egypt, Gaza Strip and West Bank, Greece, Italy, Lebanon and Turkey attended the meeting. After the opening of the meeting two general presentations were given concerning the “tropicalisationâ€ÂÂ� effect and the oceanography of the Eastern Mediterranean. Information regarding lessepsian species and their influence on local fisheries were also given by the representatives of each country. The participants discussed future research ideas on lessepsian species especially with respect to fisheries. The problem of Lagocephalus sceleratus was highly discussed since this species is causing considerable damage to fisher`s static nets and longlines in all the countries in the project area. The participants mentioned that some lessepsian species s uch as Siganus spp. and Saurida undosquamis, among others were successfully introduced into the local markets and in some cases of high commercial value. The marketing and commercialisation of lessepsian species was seen as of high priority. Educating the local public was also important since for example Lagocephalus spp. is a toxic species and there is a high risk of death if people consume individuals of this species. A network of experts on lessepsian species was established, which would have the responsibility to promote the issue of lessepsian species in the Mediterranean and develop a database on lessepsian species. The network will also assist the Coordination Committee through the focal points to propose solutions to avoid the harmful effects of lessepsian species on the Eastern Mediterranean fisheries. Most of the issues described in this report are at the moment relevant to the Eastern Mediterranean which however, in the near future will sur ely increase in importance in the other parts of the Mediterranean. -
ProjectFactsheetSupporting Responsible Fisheries in the Eastern Mediterranean through Scientific & Institutional Cooperation (Eastmed Year 10) - GCP/INT/363/EC (Baby 02) 2022
Also available in:
No results found.The EastMed project’s overall aim is to support the sustainable management of marine fisheries in the Eastern Mediterranean subregion to boost economies and protect livelihoods. The achievement of this goal is supported through technical assistance and capacity development initiatives targeted at national fisheries departments, as means of increasing their scientific and technical skills on fisheries management, and through the development of coordinated, participatory fisheries management plans.

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. -
Book (stand-alone)High-profileState of knowledge of soil biodiversity - Status, challenges and potentialities
Report 2020
2020Also available in:
No results found.There is increasing attention to the importance of biodiversity for food security and nutrition, especially above-ground biodiversity such as plants and animals. However, less attention is being paid to the biodiversity beneath our feet, soil biodiversity, which drives many processes that produce food or purify soil and water. This report is the result of an inclusive process involving more than 300 scientists from around the world under the auspices of the FAO’s Global Soil Partnership and its Intergovernmental Technical Panel on Soils, the Convention on Biological Diversity, the Global Soil Biodiversity Initiative, and the European Commission. It presents concisely the state of knowledge on soil biodiversity, the threats to it, and the solutions that soil biodiversity can provide to problems in different fields. It also represents a valuable contribution to raising awareness of the importance of soil biodiversity and highlighting its role in finding solutions to today's global threats. -
BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The 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.
