Occasional Paper N. 9 - July 1997
1997Also available in:
No results found.The introduction of soybeans to the southern and eastern parts of Paraguay in the early 1970s, followed by wheat in the mid-1970s, using conventional mechanised soil preparation practices with disc ploughs and harrows, initiated a process of widespread soil degradation and erosion. The technique of no-tillage was first used in Paraguay in the late 1970s. Following a slow start, its adoption by Paraguayan farmers gathered momentum increasing from 20,000 ha in 1991/92 to an impressive 250,000 ha i n 1995/96, accounting for about 19% of the land cultivated mechanically. In 1993, the Ministerio de Agricultura y Ganadeira (MAG) and the Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ) started a project aimed at adapting and further disseminating no-tillage in combination with rotations of both cash and green manure crops in the major grain producing departments of Paraguay. Since very little was known about the economics of these technologies in Paraguay, MAG in association with GTZ, initiated a detailed study which was guided by the FAO Investment Centre. In this paper, the findings of the study are summarised and discussed. -

Occasional Paper N. 6 - September 1996
1996Also available in:
No results found.In Lesotho, some externally financed agricultural development projects have appeared particularly prone to failure. One reason may be that, when designed, projects have not been subjected to sufficiently rigorous analysis, particularly with regard to expected farmers' response to extension messages. The thesis of this paper is that the impact of high inter-annual fluctuations in crop yields (and of crop prices) on farmers' expectations plays an important role in producers' decision-making, and t hat this can be measured with sufficient approximation to assess the prospects for the successful introduction of "improved" cropping technologies in small farmers' communities. Stochastic Efficiency Analysis has been applied to the mountain areas of Lesotho, where natural conditions are particularly harsh, but it has wider applicability in project formulation. The paper is based on information gathered by an FAO Investment Centre mission, which visited the Districts of Thaba T'seka and Qacha's Nek in November 1995 on behalf of the Government of Lesotho and the International Fund for Agricultural Development to identify a Sustainable Mountain Agriculture Programme for possible IFAD financing.

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. -
Book (stand-alone)Technical bookPractice of Conservation Agriculture in Azerbaijan, Kazakhstan and Uzbekistan 2016The book summarizes and presents the information on possible ways to adopt Conservation Agriculture (CA) approaches under the conditions of the countries mentioned above and makes recommendations for their further promotion. The Guidelines cover such topics as the significance and current state of agriculture in the project countries, permanent raised-bed planting technologies, zero-tillage technologies, weed varieties and main measures to control them, crop rotation, overview of CA machinery an d equipment, and laser-assisted land levelling. The Guidelines target agricultural scientists, specialists, trainers, extension consultants and interested farmers. We hope that the information in these Guidelines will contribute to the promotion of CA, increase of productivity and sustainability in irrigated areas of Azerbaijan, Kazakhstan, Uzbekistan and other countries of Central Asia.

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.
