ProjectFactsheetStrengthening Capacity for Dealing with Shrimp Infectious Myonecrosis Virus Disease - TCP/INT/3501 2019
Also available in:
No results found.Infectious myonecrosisvirus (IMNV) is an emerging disease of whitelegshrimp, and is one of only a few internationally important diseases of crustaceans listed by the World Organisationfor Animal Health (OIE), owing to its high pathogenicity; its potential for significant economic, social and/or biological impacts on countries that have not as yet been affected by the disease; and the difficulty or impossibility to treat, control or eradicate it once it has been introduced to new geographic areas. The project aimed to strengthen institutional biosecurity governance for dealing with IMNV in six countries: Brazil, China, Ecuador, Indonesia, Mexico and Thailand. -
ProjectFactsheetStrengthening Biosecurity (Policy and Farm Level) Governance to Deal with Tilapia Lake Virus - TCP/INT/3707 (Phase 1) and TCP/INT/3902 (Phase 2) 2024
Also available in:
The emergence of tilapia lake virus (TiLV) poses a significant threat to the sustainability of Nile tilapia, the second most farmed finfish species worldwide. Nile tilapia serves as a vital source of accessible animal protein, income for fish farmers and fishers, and contributes substantially to both domestic and export revenues. In 2015, the global production of tilapia, encompassing both aquaculture and capture, reached 6.4 million tonnes, valued at approximately USD 9.8 billion, with international trade amounting to USD 1.8 billion. TiLV has been verified in a number of countries across Asia, Africa, and Latin America. There is a strong possibility that the distribution of the virus extends further than currently acknowledged, posing a substantial threat to tilapia farming on a global scale. Although there are no public health implications associated with this pathogen, there exists a notable danger of TiLV spreading both within and between continents through the transportation of infected live tilapia, particularly in the absence of adequate biosecurity measures. The economic effects of TiLV has had significant consequences in a number of regions. In Israel, the wild catch of tilapia, primarily the Sarotherodon galilaeus species, in the Sea of Galilee saw a substantial decline. From an average of 257 tonnes per year, catch numbers plummeted to a mere 8 tonnes per year in 2008, a decline directly attributed to TiLV-induced disease. In Thailand, TiLV outbreaks in 2015 and 2016 resulted in fish mortality rates ranging from 20 to 90 percent. Records indicate widespread deaths among farmed Nile tilapia and red tilapia hybrids. Countries that cultivate tilapia must remain vigilant and implement suitable risk management strategies, such as improving diagnostic testing for imported stocks and unexplained tilapia mortalities, promptly reporting to biosecurity authorities, conducting active surveillance, launching public information campaigns, and establishing contingency plans. These measures are crucial for mitigating the continued spread and potential socio-economic consequences of this emerging disease. The Food and Agriculture Organization of the United Nations (FAO) plays a pivotal role in preventing the further spread and negative impacts of TiLV while also facilitating communication and dissemination of risks and knowledge on effective aquaculture biosecurity. -
Policy briefPolicy briefHow natural resource management sectors can contribute to reducing emerging infectious diseases: the example of forest ecosystems
Policy brief
2022Also available in:
No results found.This policy brief is a result of a collaboration between the Food and Agriculture Organization of the United Nations (FAO) and EcoHealth Alliance. The aim of the brief is to suggest ways, using the example of forest ecosystems, in which natural resource management sector can play a more active role in reducing risk and/or mitigating the impact of emerging infectious diseases (EIDs). This would reflect and facilitate a more holistic and upstream One Health approach as defined by the One Health High-Level Expert Panel, an advisory and scientific body to the Quadripartite Alliance for One Health (FAO-WOAH-WHO-UNEP). Based on guidance from FAO’s Governing Bodies, inter alia, the Committee on Forests, the Committee on Agriculture and its Subcommittee on Livestock, and FAO’s Regional Forestry Commissions, the recommendations from this brief are directed at national government authorities in charge of natural resource management, in addition to other relevant stakeholders involved in environmental management and land use planning. The recommendations are structured around eight illustrative entry points whereby the natural resource management sector can increase participation in efforts to reduce EID risk, thus applying a more holistic One Health approach.

Book (stand-alone)Technical bookDietary assessment
A resource guide to method selection and application in low resource settings
2018Also available in:
No results found.FAO provides countries with technical support to conduct nutrition assessments, in particular to build the evidence base required for countries to achieve commitments made at the Second International Conference on Nutrition (ICN2) and under the 2016-2025 UN Decade of Action on Nutrition. Such concrete evidence can only derive from precise and valid measures of what people eat and drink. There is a wide range of dietary assessment methods available to measure food and nutrient intakes (expressed as energy insufficiency, diet quality and food patterns etc.) in diet and nutrition surveys, in impact surveys, and in monitoring and evaluation. Differenct indicators can be selected according to a study's objectives, sample population, costs and required precision. In low capacity settings, a number of other issues should be considered (e.g. availability of food composition tables, cultural and community specific issues, such as intra-household distribution of foods and eating from shared plates, etc.). This manual aims to signpost for the users the best way to measure food and nutrient intakes and to enhance their understanding of the key features, strengths and limitations of various methods. It also highlights a number of common methodological considerations involved in the selection process. Target audience comprises of individuals (policy-makers, programme managers, educators, health professionals including dietitians and nutritionists, field workers and researchers) involved in national surveys, programme planning and monitoring and evaluation in low capacity settings, as well as those in charge of knowledge brokering for policy-making. -
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 (series)Working paperMap Accuracy Assessment and Area Estimation: A Practical Guide 2016
Also available in:
No results found.Accurate and consistent information on forest area and forest area change is important given the reporting requirements for countries to access results based payments for REDD+ . Forest area change estimates usually provide data on the extent of human activity resulting in emissions (e.g. from deforestation) or removals (e.g. from afforestation), also called activity data (AD). A basic methodological approach to estimate greenhouse gas emissions and removals (IPCC, 2003), is to multiply AD with a coefficient that quantifies emissions per unit ‘activity’ (e.g. tCO2e per ha), also called an emission factor (EF).
