Book (stand-alone)Technical bookHuman energy requirements
Report of a Joint FAO/WHO/UNU Expert Consultation
2004Also available in:
No results found.Since 1949, FAO has convened groups of experts to evaluate current scientific knowledge in order to define the energy requirements of humans and propose dietary energy recommendations for populations. The World Health Organization (WHO) joined this initiative in the early 1950s, and the United Nations University (UNU) in 1981. New scientific knowledge generated in the 20 years since the last consultation was held prompted the assembly of a new expert consultation to make recommen dations for energy requirements of populations throughout the life cycle. This publication is the report of that consultation, which took place from 17 to 24 October 2001 at FAO headquarters in Rome. The report is not meant merely to describe the energy expenditure and requirements of population groups. It is intended also to be prescriptive in supporting and maintaining health and good nutrition, defining human energy requirements and proposing dietary energy recommendations for populations. The new concepts and recommendations set forth in the report include: calculation of energy requirements for all ages; modification of the requirements and dietary energy recommendations for infants, older children and adolescents; proposals for different requirements for populations with lifestyles that involve different levels of habitual physical activity; reassessment of energy requirements for adults, based on energy expenditure estimates expressed as multiples of basal metabolic rates; classification and recommendations of physical activity levels; an experimental approach for factorial estimates of the energy needs of pregnancy and lactation; and recommendations for additional dietary energy needs in the two last trimesters of pregnancy. The report is accompanied by a CD-ROM software program and instruction manual on calculating population energy requirements and food needs. -

Book (stand-alone)Technical bookFats and fatty acid in human nutrition
Report of an expert consultation, 10 − 14 November 2008 Geneva
2010The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO), in their roles as technical agencies of the United Nations (UN), are charged with providing science-based guidance on food and nutrition to national governments and the international community. The process used to do this involves periodic and systematic reviews of scientific evidence, which often culminates with the convening of joint expert consultations to review the state of s cientific knowledge, deliberate on the issues and translate this knowledge into a definition of requirements and corresponding nutrient-based recommendations. The overall goal of these recommendations is to support health and nutritional well-being of individuals and populations. The topics covered during the recent past include energy, protein and amino acids, fats and oils, most of the vitamins and minerals and carbohydrates, with the objective of providing guidance on nutritional requirements and recommended dietary intakes.The Joint FAO/WHO Expert Consultation on Fats and Fatty Acids in Human Nutrition (hereafter Expert Consultation) was the most recent expert meeting convened, and was held in Geneva from 10 to 14 November 2008. The Expert Consultation was the third to be held on the subject of fats in human nutrition, the first expert consultation on this topic being held in 1977 (FAO, 1978) and the second in 1993 (FAO, 1994).

No Thumbnail AvailableBook (stand-alone)Training materialPlanning in government forest agencies how to balance forest use and conservation: agenda for training workshop. 1998
Also available in:
No results found.The purpose of planning for forestry development is to establish a workable framework for forest use and conservation which incorporates the economic, social and environmental dimensions on a sustainable basis. The framework is about creating a shared vision of how forests will be used and protected. This can be summed up in a single central question: Trees and forests for whom and for what? The question is not new but what is new is the perception that so many different groups have an interest in the reply. Forestry planning has traditionally been mainly concerned with the production of timber for industry and other wood products, and with forest industry development. Planning for environmental goals also has a long history but was largely restricted to designated areas for exclusive conservation. National forestry development agencies were essentially responsible for the sustained yield management on protected public forest lands and for reserved forests. The term "sustained yield " was mostly limited to wood production and therefore excluded the majority of other forest products and services. Although most forestry agencies have made progress towards multiple-use management, planning remains often biased towards timber in a wide range of countries. Many of the actions taken in order to stimulate forestry development in the immediate failed to sustain the momentum of growth in the longer term. Short term achievements sometimes resulted in degradation or destruction of the stock of natural capital needed in order to maintain growth in the future or reduced options for future end uses by degrading the forest capital. -
Book (stand-alone)Flagship2015–16年农产品市场状况
贸易与粮食安全：更好地平衡国家重点与集体利益
2015全球农产品和粮食产品贸易已在最近几十年取得快速增长，各国作为出口或进口方越来越多地参与这一贸易进程。这种趋势预计将在今后几十年中持续。因此，贸易将在全球各区域对粮食安全的程度和性质产生越来越重要的影响。我们面临的挑战就是确保农产品贸易的扩大能对消除饥饿、粮食不安全和营养不良起到促进作用，而不是阻碍作用。 本版《农产品市场状况》旨在缓解目前各方在农产品贸易对粮食安全产生的影响以及如何管理农产品贸易以确保贸易开放度的增加能惠及所有国家等问题上出现的观点两极分化现象。本书通过就一系列话题举证和说明，努力促成各方就政策选择开展有实证依据的辩论，并在政策选择过程中努力实现必要的改进。
