Optimised irrigation productivity and river health through pick and & mix strategies: catchment water cycle management, alternative cropping systems, real water savings and aquifer storage and recovery

Abstract

This report summarises the findings of an irrigation-river system analysis aimed at investigating the ramifications of introducing water demand management strategies to modify river flows, so that they more adequately replicate natural flows in the river while enhancing the overall productivity of the irrigation systems. To achieve this aim, the project focused on the following specific objectives: • To identify opportunities to modify irrigation system demand and supply parameters through improved on- and off-farm infrastructure management,changed cropping mixes, potential ground water substitution and trading options; • To assess the wider economic, environmental and social impacts of these change management strategies; • To obtain community feedback on the value of these options in meeting the economic and environmental issues arising from the implementation of water reform in irrigated catchments; • To achieve consensus between catchment stakeholders and scientists on future catchment scenarios and knowledge gaps; and • To identify opportunities for joint CRC-industry research investments in future
