59. Participation in International Workshop on Mainstreaming Spate irrigation in Higher Education will be fruitful if at the end of workshop we will be able to produce curriculum which can put the acquired knowledge into practice and solve people’s problem at grassroot level. I can quote former United Nation Secretary General Mr. Koffi Annan who once said that in ‘Africa Knowledge is not lacking. What is lacking is to put the Knowledge into practice” Materials I brought with me which can be useful to workshop 1) Development of Standard scheme design document for Rainwater Harvesting Based Irrigation 2) Tanzanian National Irrigation Policy 3) Arusha Technical College (ATC) Degree in Irrigation curriculum
