    Legume Trees and other Fodder Trees as Protein Sources for Livestock 1992

    Fodder trees and fodder shrubs have always played a significant role in feeding domestic animals. In fact, trees and shrubs are increasingly recognized as important components of animal feeding, particularly as suppliers of protein and especially in harsh environmental conditions. In such situations, the available grazing is not generally sufficient to meet the maintenance requirements of animals, at least for part of the year. This occurs, for example, in some mountainous regions and in the dry tropicswhere the grazing is also sometimes very degraded. Thus, in extensive animal production systems in the dry areas of Africa, it is generallye stimated that ligneous materials contribute up to 90% of production and account for 40-50% of the total available feed. Such figures illustrate the existing and urgent need not only for better knowledge but also for better use of such potential, particularly in the context of environmental degradation which is affecting our planet. On the other ha nd, in the humid tropics of Latin America, the South-cast Asia and Africa, foddersfrom trees and shrubs from leguminous species - are beginning to be utilized more dietary nitrogen supplements for ruminants. In this respect, new a significant move to look for new sources of protein from shrubs. However, given the increasing demand for forage and availability of low quality basal feed materials which require protein supplementation, high protein fodders from leguminous trees and shrubs could have a much more significant role in animal feeding systems throughout the developing world. In this respect, there is a need for more research to develop technically viable solutions. These solutions must also be economically and socially acceptable; they must preserve natural resources and protect the environment. In other words, the challenge is the sustainable development of fodder trees and shrubs.........

    This illustrated booklet on the cassava plant covers all the main points of crop yield, feed value of cassava roots, the problem of cyanide in cassava, harvesting and spoilage of cassava, processing of cassava into dried chips, and the preservation of the roots as silage. It also presents some information on the sweet potato and the crop yields to be expected as well as some materials on curing and storage of tubers in genera.

    This illustrated booklet teaches the farmer how to use cassava as animal feed for pigs, chickens, rabbits and ruminants. The roots, peels, and leaves all have value as animal food. Sweet potatoes and the sweet potato vine, are also animal food.

    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.

    Russian Federation: Meat sector review
    Country highlights prepared under the FAO/EBRD Cooperation
    2014
    Also available in:

    World food demand has seen massive changes, including a shift from staple foods to animal proteins and vegetable oils. In the short to medium term, this trend in global food demand will continue. There will be an increased demand for vegetable oils, meat, sugar, dairy products and livestock feed made from coarse grains and oilseed meals. There are numerous mid-term forecasts for the Russian Federation’s meat sector. Most of them agree on the following trends: (i) the consumption of poultry and p ork meat will increase; (ii) the consumption of beef will decrease or stabilize; and (iii) the Russian Federation will remain a net importer of meat on the world market. According to OECD and FAO projections, meat imports from the Russian Federation will decrease from 3 to 1.3 million tonnes, owing to an anticipated growth in domestic chicken meat and pork production. The country’s share in global meat imports is anticipated to decrease from 12 percent in 2006–2010, to 4 percent in 2021. While t he Russian Federation will continue to play an important role in the international meat market, it will fall from its position as the largest meat importing country in 2006–2010 to the fourth largest global meat importer by 2021, behind Japan, sub-Saharan African countries, and Saudi Arabia.

    FAO Strategy on Climate Change 2022–2031 2022
    The 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.
