UNESCO-IHE and MetaMeta as co-conveners of the Spate Irrigation Network, have, with support from UNW-DPC and DUPC produced this series of lectures on Spate Irrigation Systems. The series aims to capture and disseminate key aspects and emerging issues of Spate Irrigation systems relevant to rural livelihoods, and food and water security. The lectures feature experts and stories from major spate-irrigated areas from Yemen, Pakistan, Ethiopia and Sudan.
The Spate Irrigation Network aims to improve the livelihoods of those living in spate irrigated areas. It exchanges experiences and good practices, initiates and supports new programs and policies, and mainstreams education and training. It is supported by IFAD, World Bank/EKN, UNW-DPC, UNESCO-IHE/DUPC and FAO.
The Video Lecture Series on Spate Irrigation Systems is a follow-up from the "Mainstreaming Spate Irrigation in Higher Education" Workshop, jointly organized by FAO, UNESCO-IHE, UNW-DPC, The Spate Irrigation Network and MetaMeta in Delft, the Netherlands from 20-22 September 2010.

Spate irrigation systems are based on floods and related phenomena, which makes them very different from normal irrigation practices. Design considerations that apply to other irrigation systems do not apply to them. This difference, however, has not been appreciated by a number of interventions carried out to modernize or improve existing spate systems. Many of them ended up not improving or worsening their performance.
Some of the factors that make spate systems unique are:
- The large amount of sediments that ride on the flow
- The large amount of trash that comes in with the flood waters
- Scope for abrasion and impact damage
- An intricate system of water rights of various users.
Having evolved over hundreds of years, traditional spate systems take all of these into account. Any intervention to increase their efficiency should be based on these considerations.
