Session 11. Standards and International Developments
Standards Development for Microirrigation
Kenneth H. Solomon and Allen R. Dedrick
This article identifies national and international standards and engineering practices applicable to microirrigation. The organizational structure and procedures for the development of standards proposals and standards by the Irrigation Association, ASAE and the International Standards Organization are described, and the process for developing the U.S. position on international standards documents is presented. Arrangements for financing standardization within the irrigation industry are reviewed. Individual and industry involvement in standardization is encouraged.

International Developments in Microirrigation
Fedro S. Zazueta
This work argues that there has been a paradigm shift microirrigation from a simple water resource management system to a complex, knowledge intensive, management system that manipulates the chemical, physical and biological environment where the crop is grown. It discusses different developments in microirrigation technology in both developed and developing countries. It presents examples of successful applications of the technology well as possible consequences on its diffusion due to privatization, and tax deferment policies adopted by some countries. The remainder of the work reviews new developments in computer-based tools for microirrigation originating in several developed countries. These developments include: 1) automation using expert systems, real-time expert systems and conventional control techniques with low-cost sensors, 2) the use of simulation, and 3) the use of information delivery technologies and management tools based on CD-ROM and interactive multimedia.
