    As part of the FAO project Strengthening biosecurity governance and capacities for dealing with the serious shrimp infectious myonecrosis Strengthening biosecurity governance and capacities for dealing with the serious shrimp infectious myonecrosis virus (IMNV) disease, the FAO undertook a self-assessment questionnaire-based survey of the aquatic animal diseases emergency preparedness and response (EPR) systems of six participating countries, Brazil, Ecuador and Mexico (representing South/Central America) and China, Indonesia and Thailand (representing Asia), with a view to developing recommendations for improved performance. Current system strengths and weaknesses were identified by comparing each country’s EPR system elements against those elements needed for a comprehensive (ideal world) EPR system based on FAO and OIE publications (and the model used in Australia). The questionnaire covered three broad systems components: administration (e.g. resource allocation and legislation), operational components (including early warning, early detection and early response systems) and operational support systems (such as information management and communications systems). The questionnaire was structured into four sections: (1) general administration, (2) operational components, (3) support systems and (4) additional information. Section 1 (General Administration) contained questions aimed at generating information on the administrative structure and the scope of responsibilities of the Competent Authority on various elements (e.g. communication, risk analysis, contingency plan, personnel skills, etc.) that are essential when dealing with an aquatic emergency response. Section 2 (Aquatic EPR System Elements) contained questions on the priority system elements identified by the OIE; namely, early warning, early response and early detection systems. Section 3 (Support Systems) contained questions about broader supporting systems in relation to legislation, information management, communications and resourcing. Section 4 (Additional information) presented an opportunity for countries to provide any information or raise issues not adequately addressed in the questionnaire. The self-assessment survey provided insight into each country’s capabilities in terms of policies, procedures and institutional capabilities in place to detect the incursion of an emergency aquatic animal disease and to respond to that incursion by containing or eradicating the disease. Six key areas of need where EPR systems were not well developed included the following: stakeholder consultation, systems audit/review, simulation exercises, education/awareness building, documentation and dedicated resourcing. Analysis of the survey responses form the basis of 20 recommendations aimed at improving the administration and operation of national EPR systems with respect to early warning, early detection and early response to emergency aquatic animal disease incursions.

    Reducing and Managing the Risks of Acute Hepatopancreatic Necrosis Disease of Cultured Shrimp - TCP/INT/3502 2019
    Also available in:
    No results found.

    Acute hepatopancreaticnecrosis disease (AHPND) is an emerging disease that has caused mass mortality in shrimp in many countries in Asia and South America. AHPND is therefore a threat and a serious concern for the aquaculture industry, and a number of risk management measures need to be put in place to enable countries to reduce their vulnerability to this threat. Against this background, the project aimed to strengthen the competence of national authorities involved in aquatic animal health (AAH) in selected shrimp-producing countries in Asia, Near East and the Latin America and Caribbean (LAC) region to reduce the risks and potential negative impacts of aquatic disease incursions, particularly AHPND.

    Strengthening 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.

    The State of Food Security and Nutrition in the World 2023
    Urbanization, agrifood systems transformation and healthy diets across the rural–urban continuum
    2023
    This report provides an update on global progress towards the targets of ending hunger (SDG Target 2.1) and all forms of malnutrition (SDG Target 2.2) and estimates on the number of people who are unable to afford a healthy diet. Since its 2017 edition, this report has repeatedly highlighted that the intensification and interaction of conflict, climate extremes and economic slowdowns and downturns, combined with highly unaffordable nutritious foods and growing inequality, are pushing us off track to meet the SDG 2 targets. However, other important megatrends must also be factored into the analysis to fully understand the challenges and opportunities for meeting the SDG 2 targets. One such megatrend, and the focus of this year’s report, is urbanization. New evidence shows that food purchases in some countries are no longer high only among urban households but also among rural households. Consumption of highly processed foods is also increasing in peri-urban and rural areas of some countries. These changes are affecting people’s food security and nutrition in ways that differ depending on where they live across the rural–urban continuum. This timely and relevant theme is aligned with the United Nations General Assembly-endorsed New Urban Agenda, and the report provides recommendations on the policies, investments and actions needed to address the challenges of agrifood systems transformation under urbanization and to enable opportunities for ensuring access to affordable healthy diets for everyone.

    Latin America and the Caribbean - Regional Overview of Food Security and Nutrition 2023
    Statistics and trends
    2023
    Also available in:

    The 2023 edition of the Regional Overview of Food Security and Nutrition in Latin America and the Caribbean presents an update of the data and trends in food security and nutrition in recent years. The impact of the COVID-19 pandemic, the climate crisis and the conflict in Ukraine, as well as the economic slowdown, rising food inflation and income inequality have had an impact on regional figures. The most recent data shows that, between 2021 and 2022, progress was made in reducing hunger and food insecurity in Latin America and the Caribbean. However, the progress achieved is far from the targets established to meet SDG 2 of ending hunger. In addition, one in five people in the region cannot access a healthy diet and malnutrition in all its forms, including child stunting, micronutrient deficiencies and obesity continue to be a major challenge.
