Feasibility study of managed aquifer recharge for improved water productivity for Australian cotton production

Date Issued:2020-11

Abstract

Background The project ‘Feasibility study of managed aquifer recharge [MAR] for improved water productivity for Australian cotton production’ is investigating the potential to implement MAR at a regional scale in key irrigated cotton growing regions of Australia. The first focus region was the Murrumbidgee River system, with particular focus on Coleambally Irrigation Area of Operations (CIAO). This case study aimed to evaluate whether MAR could be feasible for irrigated cotton production in the Murrumbidgee region, and if so, make recommendations on further work to evaluate local hydrogeological conditions, plan the necessary site-specific infrastructure, and establish the legal, social and organisational conditions for its implementation. The broad approach taken was to draw on evidence from a holistic feasibility assessment to scope the most promising opportunities (“scenarios”) for MAR, and to test and refine these scenarios with the local stakeholder working group.
