Book (stand-alone)Technical bookLes sols sont fondamentaux pour la végétation que l’on cultive ou gère pour produire aliments, fibres, combustibles 2015Des sols sains sont essentiels pour assurer une croissance régulière de la végétation – naturelle ou gérée – qui fournit des denrées, des fibres, des combustibles et des produits médicinaux et qui assure des services écosystémiques tels que la régulation du climat et la production d’oxygène. Les sols et la végétation sont interdépendants. Un sol fertile favorise la croissance des plantes car il fournit aux plantes des nutriments, fait office de réservoir d’eau, et sert de support aux plantes qui s’y enracinent. En retour, la végétation, le couvert forestier et les forêts empêchent la dégradation des sols et la désertification en stabilisant le sol, en assurant la rétention de l’eau et le cycle des éléments nutritifs et en atténuant l’érosion provoquée par l’eau et le vent. La croissance économique mondiale et l’évolution démographique de la planète accroissent la demande de végétaux, d’aliments pour animaux et de sous-produits végétaux tels que le bois, les sols sont ainsi soumis à u ne énorme pression et les risques de dégradation augmentent par là même considérablement. Une gestion durable de la végétation – que ce soit dans les forêts, les pâturages ou les prairies – permet d’augmenter ses avantages, y compris le bois, le fourrage et la nourriture, de façon à répondre aux besoins de la société tout en conservant et en entretenant le sol au profit des générations présentes et futures.

Book (stand-alone)Technical studyOrganic materials and soil productivity
FAO Soils Bulletin 35
1977Also available in:
No results found.In the temperate zones of the world a favourable balance exists between input and decomposition of organic materials in the soil. This balance is influenced by climatic conditions and the inorganic constituents of the soil, in which the amount and type of clay minerals play an important role. the plant growth caused by the use of mineral fertilizer increases not only the economically important parts of the plants, but also the growth roots and crop residues. Furthermore, in many farms animal exc reta is used to maintain the level of soil organic matter in arable land.There are some interactions between certain clay minerals and fractions of soil organic matter which act as favourable factors for soil productivity and for plant production. -

Book (stand-alone)Technical bookThe future of food and agriculture - Trends and challenges 2017
Also available in:
No results found.What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021. -
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. -
BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.
