    Aquaculture development and coordination programme. Fish feed technology. Lectures presented at the FAO/UNDP Training Course in Fish Feed Technology, Seattle, Washington, 9 October - 15 December 1978 1980

    The need for developing suitable feeds based on locally available inexpensive ingredients has been widely recognized. Since lack of trained personnel is the main constraint in the development of fish feed technology in developing countries, the FAO/UNDP Aquaculture Development and Coordination Programme (ADCP) organized a special training course in fish feed technology at the College of Fisheries, University of Washington, Seattle, with a view to forming a small corps of fish feed specialists wh o could then be the focal points for future feed development programmes in their respective countries. The first report of the training course was presented in the report ADCP /REP/79/8. This present volume represents the edited texts of lectures presented by different specialists. Some additional material has been included for more complete coverage of the subject. Together, these texts may be considered to constitute a manual on fish feed technology, even though they were not prepared for that purpose. Twenty-six papers are included, under the general headings: (1) Digestion, physiology and anatomy; (2) nutritional bioenergetics; (3) nutritional biochemistry; (4) feedstuffs; (5) feed formulation; (6) feed manufacturing technology; (7) practical diets; and (8) quality control. Appendices include conversion tables, electrical data, and details on pelletability of selective feedstuffs, pellet die specifications, and equipment requirements for an 8 ton an hour feed mill.

    Farm-made aquafeeds 1995
    Also available in:
    No results found.

    This book is the proceedings of a meeting held in Bangkok in December 1992 on the use of farm-made feeds in Asia. It contains eleven country reviews of the topic, for Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Nepal, the Philippines, Singapore, Thailand and Vietnam. Nine technical papers are also included. Three are on-farm feed preparation and feeding strategies - for carps and tilapias, for catfish and snakehead, and for marine shrimp and prawns. Five other working papers are on economics, the selection of equipment, feed ingredients, formulation and on-farm management, and supplementary feeding in semi-intensive aquaculture, all directed at farm-made, rather than commercial feeds. The ninth working paper is a regional overview of aquafeeds in Asia. An analysis of the material in the eleven country papers is also presented.

    Global Forest Resources Assessment - FRA 2020 - Terms and Definitions
    Working Paper No. 188
    2018
    FAO has been coordinating global forest resources assessments every five to ten years since 1946. The assessments have to a great extent contributed to the improvement of concepts, definitions and methods related to forest resources assessments. Strong efforts have been made to harmonize and streamline reporting with other international forest-related processes e.g. within the framework of the Collaborative Partnership on Forest (CPF), as well as with the partner organizations of the Collaborative Forest Resources Questionnaire (CFRQ) and the scientific community, all in order to harmonize and improve forest related definitions and reduce reporting burden on countries. The core definitions build on earlier global assessments to ensure comparability over time. Whenever new definitions are introduced or old definitions modified this is done taking into consideration recommendations from experts in various fora.

    The State of Food Security and Nutrition in the World 2020
    Transforming food systems for affordable healthy diets
    2020
    Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions.The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic.The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

    Land tenure and rural development 2002
    This guide on Land tenure and rural development has been prepared to familiarize readers with key issues in land tenure, especially as they relate to food insecurity and rural development situations. Land tenure issues are frequently ignored in rural evelopment interventions, with often long-lasting, negative results. Analysis of how land tenure works in practice – as evidenced by who has what type of access to land and under what conditions – is essential. This guide is designed to assist tec hnical officers in governments and civil society in understanding why and how land tenure issues should be considered in rural development projects. It analyses important contexts such as environmental degradation, gender discrimination and conflicts, where land tenure is currently of critical concern. While the guide cannot provide jurisdiction-specific advice, it is intended to be relevant to those working in rural development projects throughout the world. Because tenure issues vary conside rably from one country to another, and even within a country, the guide does not attempt to provide readers with a detailed knowledge of land tenure. Instead, it provides guidance on how to identify whether or not land tenure issues are likely to occur in a rural development project, and gives recommendations as to how appropriate land tenure expertise can be built into project design and implementation.
