Systems- & people-centred water and irrigation

Using knowledge of irrigation management, I responded to a remark by Melvyn Kay who in 2002 asked if demand management could be applied to the ecological water sector. In other words, during conditions of water scarcity, could less water be apportioned to all sectors including environmental flows, while maintaining ecological functioning and productivity?
My response to this question resulted in the 2003 CIWEM publication, cited:Lankford, B. A. 2003. Environmental water requirements: A demand management perspective. CIWEM. Journal of the Chartered Institution of Water and Environmental Management. Vol 17, No. 1: 19-22 (PDF).
More recently, with Jamie Pittock (WWF), we co-wrote a follow-up publication: Pittock, J. and Lankford, B.A. 2010. Environmental water requirements: demand management in an era of water scarcity. Journal of Integrative Environmental Sciences, 7(1):1–19.
