Book Description

Planning and Evaluation of Irrigation Projects: Methods and Implementation presents the considerations, options and factors necessary for effective implementation of irrigation strategies, going further to provide methods for evaluating the efficiency of systems-in-place for remedial correction as needed.

As the first book to take this lifecycle approach to agricultural irrigation, it includes real-world examples not only on natural resource availability concerns, but also on financial impacts and measurements.

With 21 chapters divided into two sections, this book is a valuable resource for agricultural and hydrology engineers, conservation scientists and anyone seeking to implement and maintain irrigation systems.

  • Uses real-world examples to present practical insights
  • Incorporates both planning and evaluation for full-scope understanding and application
  • Illustrates both potential benefits and limitations of irrigation solutions
  • Provides potential means to increase crop productivity that can result in improved farm income
