This handbook is a training tool to learn how to run AquaCrop. AquaCrop is a crop water productivity model developed by the Land and Water Division of FAO to address food security and to assess the effect of environment and management on crop production. AquaCrop simulates yield response to water of herbaceous crops, and is particularly suited to address conditions where water is a key limiting factor in crop production.

Water resources are linked to the global challenges of food insecurity and poverty, as well as to climate change adaptation and mitigation. In line with the Sustainable Development Goals (SGD), FAO works towards several dimensions of sustainable development, including the promotion of coherent approaches to efficient, productive and sustainable water management, from farm to river basin scales. Accordingly, FAO is enhancing well-informed on-the-ground decision-making processes on water management through projects, knowledge advancement, information-sharing and tools development, such as AquaCrop, the FAO crop-water productivity model. This model assists in assessing the effects of environment (including atmospheric CO2 concentration) and management on crop production through the simulation of yield response to water of herbaceous crops. It is particularly suited to address conditions where water is a key limiting factor in crop production. In 2009, FAO officially launched AquaCrop, being the result of several years of collaborative work among scientists, water and crop specialists and practitioners worldwide, bringing together previously fragmented information on crop yields in response to water use and water deficit. AquaCrop has evolved over the different versions released since its first launch, but it always balances accuracy, simplicity and robustness. This has enabled it to remain faithful to its goal, i.e., to be a dynamic tool accessible to several types of users, mainly practitioner-type end users, in different disciplines and for a wide range of applications. In addition, AquaCrop may be considered a valuable tool by research scientists for analysis and conceptualization.

People use lots of water for drinking, cooking and washing, but significantly more for producing things such as food, paper and cotton clothes. The water footprint is an indicator of water use that looks at both direct and indirect water use of a consumer or producer. Indirect use refers to the 'virtual water' embedded in tradable goods and commodities, such as cereals, sugar or cotton. The water footprint of an individual, community or business is defined as the total volume of freshwater that is used to produce the goods and services consumed by the individual or community or produced by the business. This book offers a complete and up-to-date overview of the global standard on water footprint assessment as developed by the Water Footprint Network. More specifically it: o Provides a comprehensive set of methods for water footprint assessment o Shows how water footprints can be calculated for individual processes and products, as well as for consumers, nations and businesses o Contains detailed worked examples of how to calculate green, blue and grey water footprints o Describes how to assess the sustainability of the aggregated water footprint within a river basin or the water footprint of a specific product o Includes an extensive library of possible measures that can contribute to water footprint reduction

By 2050, the world’s population will reach 9.1 billion, which requires an increase of food production by 70 percent compared to 2005 (FAO,2018). Nearly all the increase will occur in developing countries, where agriculture plays a major role to provide employment, income and to improve food security. One of the major challenges of increasing food supply is the limited water resources. Agriculture, as the driver of freshwater exploitation has, therefore, to be transformed into more resource efficient production (FAO, 2003). The world’s limited freshwater resources are potentially threatened by the expansion of agriculture. Increasing the potential output per amount of water used is an appropriate practice to improve production efficiency while protecting water resources. Therefore, increasing the productivity of agricultural water use in a sustainable manner is essential to ultimately sustain the social and economic conditions of livelihoods. Crop water productivity has grown into one of the major approaches to cope with water scarcity and advance crop-water relation. The number of conceptual frameworks and implications is ample, but there is always a growing need to review the step-by-step approach beyond. In this Field guide, practical pathways are presented to provide a comprehensive approach for assessing and improving crop water productivity in small-scale agriculture. The Field guide draws lessons learned in three countries (Burkina Faso, Morocco and Uganda) within the framework of FAO project “Strengthening Agricultural Water Efficiency and Productivity at the African and Global Level” funded by Swiss Agency for Development and Cooperation (SDC).

This book combines multidisciplinary studies on the environmental consequences of intensified use of land and water, and the fusion of land to provide food for a growing population. Studies on water, vegetation, and soil are addressed from an environmental management perspective with a special focus on the relation between natural elements and humans. This book considers the essential dynamics of humans and the natural environment, which is especially important in areas with shallow water-table that influence directly on agricultural activities (crops, livestock, and forests), land management, flooding, droughts, waterlogging, salt-affected soils (saline and sodic) and variation in obtained water quality in wells where these processes as related to the local and regional geomorphology control. The studies present hydrological processes towards the definition of an adequate use of soil and water with consequences of its management on the environment. Also, water study procedures are presented as well as their relation to other elements of the landscape. Methodologies such as the Tóthian flow system concept are recognized by different authors to provide the reader with solid interdisciplinary analyses of related environmental components such as soils, vegetation, surface water, geomorphology, geological framework and groundwater physical-chemical composition.

The content of this guide is twofold: to describe the most important weather and agroclimatic products that are available by the National Meteorological Service (NMS) and to identify the most important needs of farmers concerning climate information. Special consideration will be given to the local knowledge used by rural farmers, too often neglected, but a key factor to their ability to cope with climate variability and change. An additional objective of this guide is to improve communication among the NMS staff, in particular, meteorologists and agrometeorologists and to encourage Agro-Pastoral Field School (APFS) trainers and facilitators to be more aware of their respective availability. Furthermore, one of the most important aims is the exchange of agroclimatic information that corresponds to the needs of all concerned, thus facilitating the assessment of the existing climatic risks in farming activities. The integration of the Response Farming in Rainfed Agriculture (RF) approach into Farmer Field School (FFS) is feasibly an effective way to reconcile NMS products with the needs of farmers. RF is a method used for identifying and quantifying rainfall variability at a local level to assess the climatic risks of farming communities. The Climate-Responsive Farming Management (CRFM) approach is an enhanced version of RF that uses modern and digital technologies, such as specific computer software, automatic weather stations, real-time telecommunication and smartphone applications. This approach can be implemented at a minimum cost at the farming level.The integration of the Response Farming in Rainfed Agriculture (RF) approach into FFS is feasibly an effective way to reconcile NMS products with the needs of farmers.

Access to water in many parts of the world is increasingly challenging due to scarcity, quality issues and lack of access to adequate supply infrastructure. Currently, over 2 billion people around the world experience high water stress, and about 4 billion people experience severe water scarcity for at least one month on an annual basis. Rainwater harvesting (RWH) is increasingly seen as both an excellent alternative source of water and a valuable climate change adaptation measure. However, large-scale adoption remains challenging in many parts of the globe. This book, Rainwater Harvesting for the 21st Century, serves as a rigorous yet practical guide for a broad audience interested in the many opportunities that RWH systems can provide, including water and food security, flood management and climate change adaptation. It comprehensively covers the state of the art in RWH with practical examples of cutting-edge research and innovation in the design, operation and maintenance of RHW systems from both academics and practitioners. Highlights include: A comprehensive, transdisciplinary perspective of the latest advances in RWH techniques. Examples and case studies from around the world.

Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.
