    The State of Food and Agriculture 2019
    Moving forward on food loss and waste reduction
    2019
    The need to reduce food loss and waste is firmly embedded in the 2030 Agenda for Sustainable Development. Food loss and waste reduction is considered important for improving food security and nutrition, promoting environmental sustainability and lowering production costs. However, efforts to reduce food loss and waste will only be effective if informed by a solid understanding of the problem. This report provides new estimates of the percentage of the world’s food lost from production up to the retail level. The report also finds a vast diversity in existing estimates of losses, even for the same commodities and for the same stages in the supply chain. Clearly identifying and understanding critical loss points in specific supply chains – where considerable potential exists for reducing food losses – is crucial to deciding on appropriate measures. The report provides some guiding principles for interventions based on the objectives being pursued through food loss and waste reductions, be they in improved economic efficiency, food security and nutrition, or environmental sustainability.

    Los fertilizantes y su uso
    Una guía de bolsillo para los oficiales de extensión
    2002
    Also available in:

    Esta guía fue preparada originariamente para uso de los oficiales de extensión que trabajaban para el Programa de Fertilizantes de la FAO. La primera edición fue publicada en 1965, la tercera edición en 1978, y su reimpresión en 1986. Para esta nueva, edición 2002, la mayor parte del texto de 1978 ha sido completamente revisado. La información sobre nuevos desarrollos técnicos y conocimientos ha sido incorporada. La guía explica la necesidad de los fertilizantes minerales, su rol e n las plantas y las características del suelo que son importantes para la fertilización. Una nueva sección aporta las recomendaciones generales para cultivos seleccionados. El capítulo sobre «Cómo determinar las necesidades de fertilizantes» incluye información sobre los síntomas de deficiencia y análisis de suelo y de los tejidos de las plantas. Un capítulo es dedicado a explicar y dar sugerencias sobre la presentación de demostraciones de fertilizantes y de las técnicas de ex tensión en general. Las recomendaciones para cultivos seleccionados están basadas en gran parte en IFA «Manual Mundial sobre el Uso de Fertilizantes», 1992. Una información más detallada se encuentra en el Manual disponible en IFA, París *. Inclusive la información mucho más completa dada en el Manual a menudo requerirá modificaciones por el usuario para tomar en cuenta las recomendaciones oficiales de los fertilizantes para los cultivos y suelos locales.

    The State of Food Security and Nutrition in the World 2021
    Transforming food systems for food security, improved nutrition and affordable healthy diets for all
    2021
    In 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.
