DocumentOther documentAssessment of irrigation potential in Africa - Arc-Info: a tool for the computation of the irrigation water requirements at continental level
Télédétection et ressources en eau/Remote sensing and water resources p. 115
1995Also available in:
No results found.This article is based on the FAO study “Irrigation potential of Africa: a basin approach” and it is part of the proceedings of the international workshop on “Remote sensing and water resources” (http://www.fao.org/docrep/W7320B/w7320b00.htm) organized by FAO, in collaboration with the Comité interafricain d'études hydrauliques (CIEH), the Laboratoire commun de télédétection Cemagref-Engref (LCT) and Orstom (Institut français de recherche en coopération) and published in 1997. The study FAO undertook in 1995 investigated the potential use of remote sensing and geographic information systems in water resources assessment of small watersheds in semi-arid areas of West Africa. The use of the Arc-Info geographic information system allowed to define the geographical computation units, which are homogeneous regarding average rainfall, potential evapotranspiration, cropping pattern (calendar, intensity) and irrigation efficiency. Combining information on gross irrigation water requirements, area of soils suitable for irrigation and available water resources by basin eventually resulted in an estimation of the physical irrigation potential for Africa. -
Book (series)BulletinIrrigation in the Middle East region in figuresAquastat Survey – 2008 2009
Also available in:
The AQUASTAT Programme was initiated with a view to presenting a comprehensive picture of water resources and irrigation in the countries of Africa, Asia, Latin America and the Caribbean and providing systematic, up-to-date and reliable information on water for agriculture and rural development. This report presents the results of the most recent survey carried out in the 18 countries of the Middle East region, and it analyses the changes that have occurred in the ten years since t he first survey. Following the AQUASTAT methodology, the survey relied as much as possible on country-based statistics and information. The report consists of three sections. Section I describes in detail the methodology used. Section II contains the regional analysis which presents a synopsis on water resources development and irrigation in the region, including a more detailed description of four transboundary river basins: the Euphrates-Tigris, Kura-Araks, Asi-Orontes and Jord an river basins. Section III contains the detailed profiles on the situation in each country. -
Brochure, flyer, fact-sheetBrochureAQUASTAT - Global information system on water and agriculture 2003This information brochure describes AQUASTAT, FAO’s global information system on water and agriculture, operational since 1993. It collects, analyses and disseminates data and information by country and by region. Its aim is to provide users interested in global, regional and national analysis (e.g. policy-makers, decision-makers and researchers) with the most accurate, reliable, consistent and up-to-date information available on water resources and agricultural water management. All AQUASTAT products are available on the Web site and as published reports or on CD-ROM.

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. -
ArticleJournal articleNurturing Soil Life through Agroforestry – The Roles of Trees in the Ecological Intensification of Agriculture 2023
Also available in:
No results found.Soil resources constitute the very foundation of agriculture, so sustainable agriculture is inherently dependent on soil health. Soil health reflects the capacity of soil to respond beneficially to agricultural management, maintaining both agricultural production and the provision of varying ecosystem services, nutrient cycling, and biodiversity conservation in the long term. Soil health depends on the physical, chemical, and biological conditions of the soil that are required for plant growth and development. Ecological intensification differs from current strategies for agricultural intensification by embracing agroecological transitions to more sustainable agriculture and food systems. This chapter discusses the pivotal role that trees play in building and maintaining the soil health and functional resilience that are required for the ecological intensification of agriculture. It summarizes the current knowledge about functions and impacts of trees on soil health, and highlights the tree/soil biodiversity interactions that drive these functions. -
Book (stand-alone)Technical bookTracking progress on food and agriculture-related SDG indicators 2025 2025The achievement of the Sustainable Development Goals (SDGs) set by the 2030 Agenda is now more crucial than ever, as the target date draws near and many goals are still far from being achieved. Countries across the globe are grappling with an array of complex and interconnected challenges, including ongoing conflicts, health crises, biodiversity loss, the escalating impacts of climate change, and political and economic tensions. FAO is the custodian agency for 22 SDG indicators spanning Goals 2, 5, 6, 12, 14 and 15. Among its key responsibilities as a custodian agency is to curate the indicator methodologies, collect, harmonize and compile data from countries, as well as disseminate and analyse data at global level. This report provides an analysis of regional and global figures and trends for the 22 SDG indicators under FAO's responsibility, thus fulfilling one of FAO’s key roles as custodian agency. The world is at a moderate distance from achieving roughly half of the food and agriculture-related SDG indicators under FAO custodianship; one-quarter of the indicators are close to being achieved, whereas another quarter remains far or very far from being achieved. Meanwhile, progress since 2015 has deteriorated on over three-fifths of the indicators; one indicator has stagnated; whereas only the remaining one-third of indicators have registered an improvement or slight improvement.
