MeetingMeeting documentEstimation of bycatch and discard by Iranian fishing vessels (Gillnets) in IOTC area of competence in 2012 2013

No results found.In order to assess the level of bycatch and discard of Iranian tu fishing vessels (Gill nets) in the IOTC competence of area, observers (port samplers) were placed in three main fishing harbors; where tu vessels landing there. We also carried out interviews with some fishermen of the vessels. Filly the log books of the vessels were controlled and compared against the information which was collected by the port samplers. In this study we assessed the amount of catch, bycatch and discard for ten I ranian vessels. Data collection was carried out by observers who are professiol in identification of species and were familiar with the Iranian tu fishing fleets. The period of study was from 10 October to end of December 2012. The areas fished by the vessels were the north-west Indian Ocean (latitude 5-25o (N) and longitude 50-70° (E)). Base on current study results, around 86.4% (211381 Kg) of catch comes from Tu and Tu like species while, around 13.6% (33273 Kg) catch belong to bycatch and di scards. According to the results, target species composition mainly were Skipjack, yellow fin, Kawakawa and big eye respectively. In total the catch composition of the vessels contained 49.8% (121838 Kg) of Tu species, 36.6% (89543 Kg) Tu like species, 7.5% (18349 Kg) different species of sharks and 6.1% (14924 Kg) other species and discard. This is considerably important that, we have never seen any mammals or marine Turtles in catch composition as a bycatch, but we received some information fr om fishermen about them. The total vigation of the vessels was 566 days, in average 56.6 days for a vessel. Because of sailing to destition, location surveys and weather conditions, there was no catches during 15 days and active fishing days for each vessels were 41.6 days in average. The average catch for each vessel was about 24.5 Tons during the vigation. Normally only one gill net installed into the Sea and investigated during a day by fishermen, so the amount of CPUE (Catch/Days) was calcul ated 589 Kg. Base on received information, there are some problems on identification of species. So I.R.Iran recommend allocation funds by IOTC or other competence authorities for technical and fincial assistance of the region by developing a regiol plan to train the related experts and implement some researches to monitor gill net fishing activities bycatch and discard. -

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -
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.
