    Emissions due to agriculture
    Global, regional and country trends 2000–2018

    The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.

    El estado mundial de la agricultura y la alimentación 2020
    Superar los desafíos relacionados con el agua en la agricultura
    2020
    Limitaciones cada vez mayores del abastecimiento hídrico amenazan la seguridad alimentaria y la nutrición. Por consiguiente, se hace necesario actuar con urgencia a fin de lograr un uso más sostenible y equitativo del agua en la agricultura. La producción agrícola de regadío sigue siendo, de lejos, el principal usuario de agua dulce, pero la escasez de este recurso constituye un problema cada vez mayor debido al incremento de la demanda y a la competencia por su utilización. Al mismo tiempo, la agricultura de secano se enfrenta a la creciente variabilidad de las precipitaciones como consecuencia del cambio climático. Estas tendencias exacerbarán las disputas entre usuarios del agua y la desigualdad en el acceso a los recursos hídricos, especialmente para los pequeños agricultores, la población rural pobre y otras poblaciones vulnerables. En El estado mundial de la agricultura y la alimentación 2020 se presentan nuevas estimaciones de la difusión de los problemas de escasez de agua en la agricultura de regadío y déficit hídrico en la agricultura de secano, así como del número de personas afectadas. Se constatan diferencias importantes entre los países y una considerable variación espacial dentro de ellos. A partir de estos datos, se examina la forma en que los países pueden determinar políticas e intervenciones apropiadas, las cuales dependerán de la naturaleza y la magnitud del problema, pero también de otros factores, como el tipo de sistema de producción agrícola, el nivel de desarrollo del país y sus estructuras políticas. Basándose en este examen, la publicación ofrece orientación para que los países puedan asignar prioridad a políticas e intervenciones destinadas a superar las limitaciones de la disponibilidad de agua en la agricultura y garantizar, al mismo tiempo, el acceso eficiente, sostenible y equitativo al recurso.

    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.
