Brochure, flyer, fact-sheetBrochureWeed management in wheat fields in the cold winter desert of Uzbekistan 2023
Also available in:
No results found.The extent of damage due to weeds depends on the type of weeds, crop stage, and duration of competition between weeds and wheat crop. In an early (September) planted wheat crop, weeds can be a problem before winter and should be controlled. A greater weed problem occurs in spring after winter rainfall and when not possible to walk in the field. Weed infestation that occur before winter can become a serious problem in early spring making it difficult to control due to high density and extensive growth of both weeds and wheat crop -

Book (stand-alone)Technical bookWheat Landraces in Farmers' Fields in Turkey: National Survey, Collection and Conservation, 2009-2014 2015

No results found.Turkey is located at a unique position from the view point of plant genetic diversity. Due to its great variety in geomorphology, topography, and climate, Turkey has a large diversity of habitats so it is very rich in plant species and endemism. One plant, perhaps the most important one, is wheat. Wheat is one of the most important agricultural commodities in Turkey, and the country ranks among the top ten wheat producers in the world. Wheat is a staple and strategic crop and an essential food i n the Turkish diet, consumed mostly as bread, but also as bulgur, yufka (flat bread), and cookies. Total annual wheat production is estimated at 19.6 million metric tons, valued at approximately US$6.9 billion in 2010. Total production area is approximately 8 million ha (FAO, 2012). Value addition via processing makes the wheat industry one of the major sectors in the economy. The study showed that wheat landraces are being produced by farmers in generally remote areas for subsistence farming. T he number of farmers producing wheat landraces and different wheat landrace populations are likely decreasing. As a country, Turkey has a good strategy to conserve them in gene banks (ex situ conservation), but should focus more on their maintenance under farmers’ conditions (in situ conservation) and improve conservation and sustainability strategies using organic farming practices, geographical indicators, mountainous production practices, and emphasis on local products.

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.

Book (stand-alone)Technical studyFish stock assessment manual 2003
Also available in:
This manual starts with an introduction to the mathematical models applied in fish stock assessment. The basic assumptions about a model and the concepts of variation rates of a characteristic in relation to time are presented. The concept of cohort and models for the individual growth of the cohort are developed. In the chapter concerning the study of the stock, the fishing pattern and its components are defined, the most used models for the stock-recruitment relation are presented, as well as the short- and long-term projections of a stock. With regard to fishing resources management, the discussion is focused on the biological reference points. Finally, the general methods of estimating parameters are described, with special relevance to the cohort analysis by age and length. Then a solution of the exercises from the last course held in IPIMAR, is presented by the author and the scientist Manuela Azevedo.
