No Thumbnail AvailableBook (series)Technical bookConstruction de bateaux de pêche: 3. Construire un bateau de pêche en ferrociment. 1995La rareté et le coût croissants de bois résistant pour la construction de bateaux ont affecté la construction des bateaux de pêche partout dans le monde. Les pays développés ont été largement les témoins du passage de la construction traditionnelle en bois vers des techniques de construction moins conventionnelles (i.e. contre-plaqué et lamellés) ou des matériaux différents tels que plastique renforcé de verre tissé (PRVT), acier, aluminium et ferrociment. Ces techniques permettent généralement des méthodes de construction employant une main d'oeuvre réduite. Dans les pays en développement où le bois est encore le matériau le plus employé dans la construction navale, la rareté et le prix élevé de bois de bonne qualité n'ont pas conduit à une réduction des constructions de bateaux, mais c'est plutôt la qualité de la construction qui a diminué, du fait de l'utilisation de bois de mauvaise qualité. En même temps cependant, des essais ont été effectués pour diversifier les méthodes de cons truction avec des succcès variés. Le but de ce document est d'aider ceux qui envisagent la construction en ferrociment. On suppose que ceux qui utilisent ce livre sont déjà familiarisés avec la construction de petits bateaux de pêche.

Construire un bateau non ponté en stratifié de verre
2011Dans de nombreuses régions du monde, il devient difficile de trouver le type de bois requis pour construire un bateau de bonne qualité, de sorte que de nombreux constructeurs commencent à se tourner vers le stratifié de verre. Les informations données dans ce manuel concernent spécifiquement la construction d’un bateau de pêche non ponté de 4,5 m, appelé MDV-1. Il s’agit d’une embarcation simple, facile à manoeuvrer, sûre et conçue pour être propulsée à la rame et au moteur. Sa concept ion générale en fait un bateau adapté aux eaux côtières du monde entier

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. -

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. -
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.
