An overview of subsurface irrigation techniques

Andrea Dührkoop and Oliver Hensel, University of Kassel, Germany

Chapter synopsis: Water is a scarce resource which plays a crucial role in agriculture. As climate change and population growth increase the strain on water supplies, involved actors are forced to look for water-saving irrigation methods for food production. This chapter reviews four key subsurface irrigation techniques: clay pot (pitcher) irrigation, auto-regulative subsurface pipes, subsurface drip irrigation (SDI) and porous pipe irrigation. Advantages, disadvantages and case studies for each technique are presented. In the final sections, subsurface irrigation with treated wastewater and a model for designing irrigation systems are also discussed.
