Living Lightly: Let's leave no-one behind on World Water Day
March 22 is global World Water Day, a day on which we should think about the significance of fresh water and sustainability in managing fresh water resources.

DO BETTER: Food production techniques have caused salinity, erosion, blue-green algal blooms, fish kills and reduced water quality in the Murray-Darling Basin. We must develop a way forward where water is shared.
This year's theme is "Leaving no-one behind".
Unfortunately, current water use practices don't benefit everyone. Globally, 80 per cent of the people who must use unsafe and unprotected water sources live in rural areas. Access to water underpins public health.
Indeed, leaving no-one behind is critical to sustainable development and a stable future.
Lessons can be found closer to home. The Murray-Darling Basin plan is perhaps one of the most ambitious social and governmental projects undertaken. Individuals, communities and regions face a range of changes to the way we use water, in terms of materials and well-being.
The importance of irrigated agriculture in the basin is hard to overstate. However, food production techniques have started causing salinity, erosion, blue-green algal blooms, fish kills and reduced water quality. This in turn affects a range of indigenous groups, recreational fishers, stock and domestic users, as well as those of us who value river ecologies.
Evidence of illegal take and fish kills in the Darling River suggest we need to do better.
Both the Productivity Commission's assessment of the basin plan and the recent South Australian Royal Commission have called for greater transparency and public participation in planning. More recently, ANU researchers claimed $3.5 billion of taxpayers' money spent on water-saving infrastructure projects in the basin had returned little or no new water.
Imperatives of fairness or social justice are not front and centre in the Water Act — a strict interpretation suggests science will determine what the environment needs and that the task for government (including the MDBA) is then to "do what science tells us to do".
Given the importance of the basin, it is important to have a set of value judgments that underpin what we do. On Friday, I would urge we focus on beginning to re-define the principles that underpin water management, engage all of us who have a stake in this vital issue, and develop a way forward that means water is shared.
I would urge we ... develop a way forward that means water is shared.
We should begin leaving no one behind in the Murray-Darling Basin.
