Dry areas suffer not only from limited rainfall but also natural leakage 90% of rainwater is lost directly or indirectly, and is unavailable for agriculture or domestic use. Water harvesting is a low-cost, easy-to-use, environmentally-friendly way to recover a large part of this lost water.

How does water harvesting work? Which sites or areas are best suited and how can these areas be identified? How to design, build and maintain a water harvesting system tailored to local needs? How can water harvesting contribute to combating land degradation, enhancing food security and adapting to climate change? This book provides the answers.

The book is based on many years of research, training and development by three of the world s leading experts in water management and agriculture. It is authoritative, comprehensive, and easy to read, containing practical examples, many illustrations and little jargon. This volume will be of great interest to researchers, development workers, farmers, policymakers, students of the natural sciences in fact, anyone interested in efficient, sustainable management of water resources and agriculture.

As global pressure on water resources intensifies, it is essential that scientists understand the role that water plays in the development of crops and how such knowledge can be applied to improve water productivity. Linking crop physiology, agronomy and irrigation practices, this book focuses on eleven key fruit crops upon which millions of people in the tropics and subtropics depend for their livelihoods (avocado, cashew, Citrus spp., date palm, lychee, macadamia, mango, olive, papaya, passion fruit and pineapple). Each chapter reviews international irrigation research on an individual fruit crop, identifying opportunities for improving the effectiveness of water allocation and encouraging readers to link scientific knowledge with practical applications. Clearly written and well illustrated, this is an ideal resource for engineers, agronomists and researchers concerned with how the productivity of irrigated agriculture can be improved, in the context of climate change, and the need for growers to demonstrate good irrigation practices.

The reuse of wastewater in irrigation is being practiced only recently to solve water scarcity problems in agriculture. Management of water, soil, crop, and operational procedures, including precautions to protect farm workers, play an important role in the successful use of sewage effluent for irrigation. Appropriate water management practices must be followed to prevent salinization. If salt is not flushed out of the root zone by leaching and removed from the soil by effective drainage, salinity problems can build up rapidly. Leaching and drainage are, thus, two important water management practices to avoid salinization of soils. One of the options that may be available to farmers is the blending of treated sewage with conventional sources of water to obtain a blended water of acceptable salinity level. This important book focuses on the use of wastewater as a valuable resource for agricultural micro irrigation purposes. It covers effective wastewater management practices in a variety of climates, including semi-arid regions and others; how to perform effective evaluations to gauge the quality of the water on plants, including potatoes, maize, and eggplant; and the cost-benefit of using wastewater. It addresses the sources of wastewater for irrigation and the problems along with challenges, including water quality, clogging, soil quality, and more. The mission of this compendium is to serve as a reference manual for professionals in biological and civil engineering, horticulture, soil and crop science, and agronomy, as well as for graduate and undergraduate students in related fields. It will be a valuable reference for professionals who work with micro irrigation/wastewater and water management, for technical agricultural centers, irrigation centers, agricultural extension services, and other agencies that work with micro irrigation programs.

Rainfall levels are rarely optimal, but there are hundreds of things you can do to efficiently conserve and use the water you do have and to reduce the impact of drought on your soil, crops, livestock, and farm or ranch ecosystem. Author Dale Strickler introduces you to the same innovative systems he used to transform his own drought-stricken family farm in Kansas into a thriving, water-wise, and profitable enterprise, maximising healthy cropland, pasture, and water supply. Ranging from simple, short-term projects such as installing rain-collection ollas to long-term land-management planning strategies, Strickler's methods show how to get more water into the soil, keep it in the soil, and help plants and livestock access it.

Better water management will be crucial if we are to meet many of the key challenges of this century - feeding the world's growing population and reducing poverty, meeting water and sanitation needs, protecting vital ecosystems, all while adapting to climate change. The approach known as Integrated Water Resources Management (IWRM) is widely recognized as the best way forward, but is poorly understood, even within the water sector. Since a core IWRM principle is that good water management must involve the water users, the understanding and involvement of other sectors is critical for success. There is thus an urgent need for practical guidance, for both water and development professionals, based on real world examples, rather than theoretical constructs. That is what this book provides.

Using case studies, the book illustrates how better water management, guided by the IWRM approach, has helped to meet a wide range of sustainable development goals. It does this by considering practical examples, looking at how IWRM has contributed, at different scales, from very local, village-level experiences to reforms at national level and beyond to cases involving trans-boundary river basins. Using these on-the-ground experiences, from both developed and developing countries in five continents, the book provides candid and practical lessons for policy-makers, donors, and water and development practitioners worldwide, looking at how IWRM principles were applied, what worked, and, equally important, what didn't work, and why.

In this book, Leslie Small and Ian Carruthers examine in detail the potentials and limitations of user fees for financing irrigation operation and maintenance. Both authors have extensive field experience in irrigation in developing countries and have combined this experience with simple concepts of economics to examine possible institutional and financial reforms which would not simply ask farmers to pay for an inadequate irrigation service, but would create the potential for significant improvements in the quality of the service provided. The proposed elements of any such reform are discussed in depth - a system of user fees covering the recurrent costs of irrigation; a financially autonomous irrigation agency that can retain and use the fees to operate and maintain the irrigation facilities; and a macro policy environment that is not unduly skewed against the agricultural sector. Written in a style intended to convey economic perspectives and insights to non-economists, this book will be essential reading for all those concerned with the financing and performance of irrigation in developing countries.

Modeling aspects have added a new dimension in research innovations in all branches of engineering. In the field of soil and water engineering, they are increasingly used for planning, development, and management of land and water resources, including analysis of quantity and quality parameters of surface and ground water, flood forecasting and control measures, optimum allocation and utilization of irrigation water. The application of these models saves considerable time in decision support systems and helps in conservation and optimum allocations of scarce precious natural resources.

Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.

At last, integrated management of drought on farms is dealt with in one comprehensive book. Although drought is a highly variable, near-universal natural phenomenon which has repercussions on a country's water and food supplies and many other sectors of the economy, there are many ways of avoiding, resisting and mitigating the effects of drought. Pro-active preparedness entails using the principles of risk management to upgrade the drought resistance of a farm systematically, and to have auxiliary contingency plans at the ready for use during unusually long droughts. The book provides tools for these strategies as it covers the management of water, soils, crops, rangeland, fodder and livestock, and many other drought-related topics. Audience: This book will be an important source of information for university and college staff and students in agricultural sciences, water and land use, environmental management, geography and risk management, and also farmers, agricultural advisors and policy makers.

Fluctuation in rainfall in Ogun-Osun River Basin, Nigeria in the recent times is a challenge to crop production. Therefore, agronomic practices need to be designed to improve water productivity under rainfed conditions. Improving water productivity requires vapour shift or transfer whereby soil physical conditions, soil fertility, crop varieties and agronomy are applied in tandem and managed to shift the evaporation into useful transpiration by plants. Water conservation practices: Tied ridge, Mulch, Soil bund, Tied ridge plus Soil bund, Tied ridge plus Mulch, Mulch plus Soil bund and Direct sowing were used in cultivating Soybeans for two rainy seasons in Ile-Ife, Nigeria. Full and deficit irrigation application during reproductive stages were used with in-line drip irrigation for two seasons. Seasonal rainfall influenced the water storage in the soil. Transpiration, seed yield and water productivity were related to Total Intercepted Photosynthetically Active Radiation. Yield and economic productivity increased under water conservation practices. Productivity decreased most when irrigation was skipped during seed filling and the production costs under drip system are high. Rainfed cultivation of soybeans when rainfall and solar radiation are optimum, is the best option. The AquaCrop model was calibrated and validated to predict canopy cover, aerial dry biomass, seed yield, soil water content, crop water use, and water productivity under full and deficit irrigation conditions. The model performed the best in simulating aerial dry biomass under full irrigation. The simulated and measured data compare adequately and the performance of the model was satisfactory.
