    Biosocioeconomics of Fishing for Small Pelagics along The Southwest Coast of Sri Lanka - BOBP/WP/96 1994
    Also available in:
    No results found.

    The marine fishery in Sri Lanka is the country’s major source of animal protein supply (60%). It also provides employment to around 100,000 fishermen. More than 90 per cent of the fish production comes from the coastal area extending up to about 25 nautical miles from the shore. A group of small pelagic species constitutes more than 45 per cent of this catch. Before the motorization of fishing craft in the early 1950s, almost the entire production of small pelagics came from the beach seine (B S). After motorization, however, small-mesh gillnets (GN) became popular. With the introduction of synthetic material, the gilinet became the major gear. In the early 1980s, fishermen on the southwest coast of Sri Lanka started using the purse seine (PS) to target small pelagic resources. The rapid increase in fishing intensity due to motorization gave rise to several fishing disputes. The use of the more efficient purse seine in the southwestern coastal waters led to several conflicts. In 198 7, the Ministry of Fisheries and Aquatic Resources (MFAR) framed regulations limiting the area of operation of the PS. However, enforcement of these regulations was not successful. The MFAR thereupon, realized the need to examine the possible interaction between the different fisheries in terms of resources and income distribution among various user-groups. It was expected that the information obtained through a study would assist in arriving at sound management measures. The study was undertake n by the Department of Fisheries and Aquatic Resources and the National Aquatic Resources Agency (NARA) with guidance from the Bay of Bengal Programme’s biosocioeconomics team. The reporting was funded by the United Nations Development Programme (UNDP).

    Exploratory Fishing for Large Pelagic Species in the Maldives - BOBP/REP/46 1990
    Also available in:
    No results found.

    This paper discusses the aims, methodology and findings of the project “Exploratory tuna fishing in the Maldives” TCP/MDV/6651(1). It was established in 1987 as part of a TCP (technical cooperation) agreement between the FAO and the Government of Maldives. The project was completed in December 1988. The project was executed by the Marine Research Station of the Ministry of Agriculture and Fisheries with some support from the BOBP (Bay of Bengal Programme for Fisheries Development). Und er the project, exploratory surveys were carried out by the vessel Matha Hari. Despite limited fishing operations, useful information was obtained on the status of pelagic fish stocks, and on the feasibility of operating multi-day gillnet-cum-longline offshore fishing trips Data were also obtained on offshore tuna and sharks. The BOBP is a regional fisheries programme that covers seven countries around the Bay of Bengal - Bangladesh,-India, Indonesia, Malaysia, Maldives, Sri Lanka and Thail and. It strives for the socio-economic betterment of small scale fisherfolk communities in the region by developing, demonstrating and promoting new ideas or techniques, new technologies, methodologies or systems to help smallscale fisherfolk.

    Biosocioeconomic Assessment of the Effect of the Estuarine Set Bagnet on the Marine Fisheries of Bangladesh - BOBP/WP/94 1994
    Also available in:
    No results found.

    The estuarine set bagnet (ESBN) fishery of Bangladesh is one of the country’s niost important traditional fisheries and a large population of small-scale fisherfolk have been dependent on it for a long time. In the last two decades, the introduction and rapid expansion of the bottom trawl fishery and of shrimp culture have contributed to problems of interaction and competition among the fisheries which exploit the same penaeid shrimp and demersal finfish stocks. The traditional, but less effic ient, ESBN fishery has not only become vulnerable, being likely to be affected by other fisheries, but may also be destructive to small penaeid shrimp and some of the finfish resources that these other fisheries exploit. The Department of Fisheries, Bangladesh, decided to investigate this issue and the Bay of Bengal Programme (BOBP) was requested to assist. The study was funded by the United Nations Development Programme (UNDP). Bioeconomic and socioeconomic surveys were undertaken in 1989/90 an d a National Seminar was held in January 1992 to discuss the results. Because of the interactive nature of many of the marine fisheries, it was necessary, for the assessment and management of any one fishery, to consider the other fisheries exploiting the same resources. Therefore, in addition to the estuarine set bagnet fishery, the fisheries employing marine set bagnets (MSBN), trammelnets (TRN), beach seines (BS), bottom longlines (BLL) and trawlnets (TWL), as well as shrimp fry-collection using pushnets (PN) and dragnets (DN), were investigated. These studies have been documented separately in BOBP working papers BOBP/WP/89 Studies of Interactive Marine Fisheries of Bangladesh and BOBP/WP/90 — The Socioeconomic Condition of the Estuarine Set Bagnet Fisherfolk in Bangladesh. The present paper is based on the results and findings of these publications and assesses the biosocioeconomic impact of the ESBN fishery on the other marine fisheries of Bangladesh. The working papers mention ed provide additional information on the respective fisheries.

    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.

    Food loss analysis: causes and solutions – The Republic of Uganda. Beans, maize, and sunflower studies 2019
    Also available in:
    No results found.

    This report illustrates the food loss assessment studies undertaken along the maize, sunflower and beans supply chains in Uganda in 2015-16 and 2016-17. They aimed to identify the critical loss points in the selected supply chains, the key stages at which food losses occur, why they occur, the extent and impact of food losses and the economic, social and environmental implications of the food losses. Furthermore, these studies also evaluated the feasibility of potential interventions to reduce food losses and waste.

    The future of food and agriculture - Trends and challenges 2017
    Also available in:
    No results found.

    What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021.
