Book (stand-alone)Technical studyAgricultural Drainage Water Management in Arid and Semi-arid Areas
FAO Irrigation and Drainage Paper
2002Also available in:
No results found.This publication deals with the underlying concepts relating to drainage water management. It first discusses the adequate identification and definition of the problem for the selection and application of a combination of management options. It then presents technical considerations and details on the four groups of drainage management options. The second part of the publication contains the summaries of the case studies from the United States of America, Central Asia, Egypt, India and Pakista n. These case studies represent a cross-section of approaches to agricultural drainage water management. The factors affecting drainage water management include geomorphology, hydrology, climate conditions and the socio-economic and institutional environment. -

Policy briefPolicy briefIrrigation performance benchmarking 2023
Also available in:
No results found.Irrigation benchmarking is a process of comparative analysis of irrigation performance that enables scheme managers to understand the performance of their irrigation services. To better understand the process of monitoring irrigation performance, this brief will use Cambodia as an illustrative example. Irrigated rice production in Cambodia has significant potential, yet performance of the sector lags behind surrounding countries, such as Viet Nam’s delta region. In addition, there are limited available and published data in Cambodia, making it difficult to analyse the current and changing state of irrigation in the country, the productivity levels, or irrigation’s contribution to poverty alleviation and economic growth. For these reasons, Cambodia was selected as a country to pilot the transfer of key learnings from the Australian experience of irrigation performance benchmarking, and to develop a benchmarking methodology as a first step to undertake ongoing performance assessment of irrigation schemes for strategic investments in increasing water productivity. -
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. -
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.
