The Handbook of Irrigation System Selection for Semi-Arid Regions compares the various types of available irrigation systems for different regions and conditions, and explains how to analyze field data to determine the suitability of the land for surface, sprinkle, or drip irrigation systems. The book focuses on strategies for irrigation development and management and examines deficit irrigation and partial root-zone drying systems. Also, solute leaching modeling under different irrigation systems, soil moisture conditions, and organic fertilizer application in arid areas are discussed. Further, it examines multi-criteria decision making for irrigation management and the appraisal of agricultural lands for irrigation in hot, sub-humid regions.

Features:

• 
  
  

• Presents comparative analysis to aid in the selection of the most appropriate types of irrigation systems according to land characteristics.

• 
  
  

• Includes numerous practical case studies.

• 
  
  

• Offers parametric evaluation systems for irrigation purposes.

• 
  
  

• Considers data from semi-arid zones, each with different sub-climates.

Focusing on semi-arid land, the book highlights parametric evaluation systems for irrigation purposes, along with the use of analytical hierarchy processes integrated with GIS to determine which systems are best suited. This comprehensive and well-illustrated handbook will be of great interest to students, professionals, and researchers involved with all aspects of irrigation in semi-arid regions.

11.1 INTRODUCTION

The agricultural expansion in the desert lands is one of the most important objectives to be taken in the plans of agricultural expansion in Iraq, in order to bridge the gap between the population increase and the deterioration of land and food needs. The study area is one of the most important areas of future expansion in terms of agricultural potential (Investment map for promising areas – Anbar Agriculture Directorate, 2009).

Assessing land suitability for irrigation is an important tool not only in planning for agricultural development but also in overcoming the global problem of scarcity of water used for food production, especially because Iraq has for many reasons prevented it; this is due to Iraq not seriously planning to establish real agricultural development until it imports everything from crops. This has had a disastrous impact on the economy of the state and the deterioration of agricultural land due to the abandonment and lack of exploitation in an optimal manner, causing a state of deterioration, especially in the case of salinity; thus, there has been an increase in the proportion of land desertification.

Water is one of the important sources of growth and development for human societies. The water crisis is a real problem worldwide. Most of the world suffers from the scarcity of its water resources, whether it is for domestic use or for agriculture, industry, and development. Consequently, water management and investment are a challenge for workers in the field of agriculture and irrigation all in dry and semidry climatic conditions, and the optimal investment of this important resource for the development and transfer of modern technology and its dissemination in irrigation projects in conjunction with the study of soil characteristics and their suitability with irrigation methods, and the utilization of all available traditional and nontraditional water resources (Albaji et al., 2008).

FAO 1997 defines surface irrigation as holding water on the surface and allowing it to soak the soil to some depth. Drip irrigation is the flow of water droplets to a s...
