Book (series)Technical reportWorld reference base for soil resources 2014
International soil classification system for naming soils and creating legends for soil maps - Update 2015
2015This publication is a revised and updated version of World Soil Resources Reports No. 84 and 103 and presents the international soil classification system. Every soil in the world can be allocated to one of the 32 Reference Soil Groups as defined in this document, and can further be characterized by a set of qualifiers. The resulting soil name provides information on soil genesis, soil ecological function and soil properties relevant for land use and management. The same system, refined slightly , may be used to name the units of soil map legends, thereby providing comprehensive spatial information. By accommodating national soil classification systems, the World Reference Base facilitates the worldwide correlation of soil information. -

No results found.After endorsement of the World Reference Base for Soil Resources (WRB) as a universal soil correlation tool by the International Union of Soil Sciences (IUSS), the Reference Base (RB) working group has endeavoured to promote, test and improve the system further . The aim of this publication is to make the WRB available to young scientists at an affordable price. This text is published in conjunction with a CD-ROM that contains additional sample profiles, analytical data and virtual field excu rsions. The document and the CD-ROM are produced jointly by the Wageningen Agricultural University (Wageningen, The Netherlands), the International Institute for Aerospace Survey and Earth Sciences (ITC, Enschede, The Netherlands), the International Soil Reference and Information Centre (ISRIC, Wageningen, The Netherlands), the Faculty of Agricultural Sciences of the Katholieke Universiteit Leuven (Belgium) and FAO. This publication succeeds the Lecture notes on the major soils of the world by P .M. Driessen and R. Dudal, eds. (1991) which were based on the Legend of the FAO Soil Map of the World. -

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.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. -
Book (series)Technical studyProducción de alimentos en acuaponía a pequeña escala – Cultivo integral de peces y plantas 2022Este documento técnico empieza introduciendo el concepto de acuaponía, incluyendo una breve historia de su desarrollo y su sitio en la amplia categoría de cultivos sin suelo y de agricultura moderna. Discute los conceptos teóricos principales de la acuaponía, incluyendo el ciclo del nitrógeno y el proceso de nitrificación, el rol de las bacterias, y el concepto del equilibrio en una unidad de acuaponía. Luego cubre aspectos importantes de los parámetros de calidad de agua, pruebas de agua, y de dónde obtener el agua para la acuaponía, así como también los métodos y teorías del diseño de unidades, incluyendo los tres métodos principales de sistemas acuapónicos: camas de cultivo con sustrato, técnicas de flujo laminar con nutrientes y cultivo de aguas profundas. La publicación discute en detalle los tres tipos de organismos (bacterias, plantas y peces) que hacen al sistema de acuaponía. También presenta estrategias de manejo y prácticas para resolución de problemas, así como temas específicamente relacionados a fuentes de acuaponía local y sostenible. Esta publicación también incluye nueve apéndices que presentan otros temas claves: las condiciones ideales para que plantas comunes crezcan en acuaponía; control biológico y químico de plagas y enfermedades, incluyendo una guía de plantas compatible; enfermedades comunes y síntomas, causas y remedios relacionados; herramientas para calcular la cantidad de amoníaco producido y los medios de biofiltración requeridos para ciertas densidades de peces y la cantidad de alimento a agregar; la producción casera de alimento para peces; los lineamientos y las consideraciones para establecer unidades de acuaponía; un análisis de costo-beneficio de una unidad de acuaponía a pequeña escala; una guía completa para construir versiones a pequeña escala de cada uno de los tres métodos de acuaponía; y, un breve resumen de esta publicación designada como material suplementario para extensionismo y educación.

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