WASP: A planning and policy tool for sustainable urban irrigation
This article by Bhakti Devi featured in the Irrigation Australia Journal, Winter 2009, Volume 24, No. 2.
With urban areas across Australia feeling the effects of drought in the last few years, the response of many water utilities has been to implement water restrictions for urban green spaces, including domestic gardens, sporting ovals and grounds and other public open spaces. While restrictions do conserve water resources, this is at the cost of the quantity and quality of the urban green space and the associated social, economic and environmental benefits. Without a tool or framework for analysing existing urban irrigation demand and determining the water saving potential of various categories of urban green spaces, it is likely that water restrictions continue to be the preferred policy option for saving water.
