DocumentOther documentCompendium on Rainwater Harvesting for Agriculture in the Caribbean Sub-region
Concepts, calculations and definitions for small, rain-fed farm systems
2014Also available in:
No results found.The purpose of this document is to provide a practical tool to train and build human capacity in the Caribbean sub-region in the practice of rainwater harvesting. Application of rainwater harvesting techniques will produce measurable improvements in livelihood and household food security, generated by access to reliable water resources for irrigation. The document is targeted to agricultural smallholders operating on two hectares of land or less, as well as backyard gardeners and school gardenin g projects. It describes simply, but carefully the relationships between plants, soil, water, climate and rainfall, and on-farm rainwater harvesting. The document uses calculations and tables to explain the concepts, charts and drawings to illustrate them. Furthermore, both metric and imperial systems of measurement are used throughout to facilitate practical application of the knowledge gained by users. It includes important definitions and reference tables to provide added guidance to users. A dditionally, each example of a rainwater-harvesting system is illustrated by the relevant drawings and/or photographs. In a step-by-step approach to knowledge-building, the document addresses the following five areas: (a) design rainfall; (b) the catchment area and storage design; (c) reference crop evapotranspiration and crop water requirements; (d) managing effective rainfall and cumulative storage; and (e) rainwater harvesting systems suitable for the Caribbean sub-region. -

Technical Paper N. 10 - 1995
1995Also available in:
No results found.The success of dryland agriculture depends on there being an adequate supply of water in the rooting zone of the soil, freely available to crop plants. Designers of investment projects to support dryland agriculture often analyse rainfall statistics in some detail. However they have tended to give less attention in project designs to measures which will promote more efficient capture and use of rainfall. This document reviews available technologies to improve in situ capture of rainfall and its more efficient use by crop plants. It concerns areas with restricted, irregular or markedly seasonal rainfall, mostly where the annual average is from 400 to 1,000 mm, but also where seasonal shortages of rainfall can limit crop productivity. It is directed to staff of the FAO Investment Centre and their counterparts in government teams responsible for project design. -

BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The 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.

Book (stand-alone)Technical bookThe future of food and agriculture - Trends and challenges 2017
Also available in:
No results found.What will be needed to realize the vision of a world free from hunger and malnutrition? 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. -
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.
