Description: This report discusses the non-modernized spate irrigation systems in Yemen. There was a surge of spate development projects in Yemen in the 1980s. A large number of spate systems were “modernized”, particularlay in the Tihama Plains and around Aden. The modernization consisted of the construction of permanent diversion weirs, the excavation and sometimes lining of canals and land leveling. For several reasons there is a need to reassess and reappreciate the traditional methods of diversion of spates. It first gives an overview of the wadi systems in Yemen. It then discusses the types of traditional systems, one that uses non-permanent structures for diversion and one that uses traditional permanent structures. It next discusses the organization around these systems, the water rights and the operation and maintenance. It concludes with a short overview of the predominant crops in the spate systems in the country.
