Irrigation and Agricultural Development compiles selected papers presented at the International Expert Consultation held in Baghdad, Iraq from February 24 to March 1, 1979. This book addresses the technical, economic, and institutional problems connected with the development and utilization of irrigation water for agricultural production. It discusses the policy framework for investment in irrigation projects; natural equilibriums and irrigated agriculture; and selection of appropriate irrigation methods for semi-arid regions. The studies on crop consumptive use of water in Iraq; world bank experience with irrigation, drainage and land reclamation projects; and salinity problems and land reclamation in the Arab Republic of Egypt are also covered. This publication is recommended for environmentalists, irrigation engineers, and agriculturists concerned with water development, conservation, and management.

The concern over groundwater contamination has focused attention on the processes that influence the fate of chemicals in soil water systems. A major concern of groundwater contamination is the passage of these chemcials through the unsaturated zone and the relatively thin cover layers overlying the aquifers. Pollution due to diffuse sources is probably the most difficult to model. This is because the loads are usually non-homogeneous and they are also governed by spatially and temporally non-homogeneous, but dynamic, processes of chemical and biochemical phenomena.In this book, the estimation techniques and transfer functions of required input data from existing databases in geographic information systems are provided. Spatially variable input data, such as the type of soil, hydrological conditions, intensity of land use and atmospheric deposit of pollutants, are derived from basic land and climate characteristics. A model for the evaluation of land use and water management is also described. In addition, examples of field and regional studies on water management and policy analysis are provided.

Water is the most basic essential for plant growth; an inadequate supply causes severe problems, as plants rely on the water transmitted by soil to meet their physiological and nutritional needs. Since the first edition was published, flooding and droughts throughout the world have made water an even more topical subject, as the importance and instability of our water supplies have been brought to the forefront of daily life. This new edition of Water Dynamics in Plant Production focuses on the dynamics of water through the hydrologic cycle and the associated mechanisms that plants employ to optimize growth and development. It describes the basic scientific principles of water transport in the soil-plant atmosphere continuum, and explains the linkage between transpirational water use and dry matter production. Paying particular attention to the various agronomic strategies for adaptation to climate-driven limitations of water resources, the efficiency of water use in plant production and in achieving an economic yield is presented in detail. This book offers a multidisciplinary introduction to the fundamentals and applications of water dynamics in natural and managed ecosystems. Including text boxes throughout, as well as online supplementary material, it provides an essential state of-the-art resource for students and researchers of soil and plant science, hydrology and agronomy.
