The Strategic

This paper and Special Issue build a case for why justice matters in water governance and why it should be explicitly accounted for in water management and allocation. It describes four characteristics of water and their implications for social and environmental justice. These four characteristics – the spatial and temporal uneven distribution of water; the fact that water is essential for all life, with minimums needed for the survival of both the environment and humankind; water's added benefits to human well-being through the goods and services it provides; and the ensuing political dimensions of power asymmetries affecting water governance – have resulted in a plethora of disciplinary interpretations of justice in an attempt to capture its relevance and importance. The collection of papers in this Special Issue provides a glimpse into the diverse range of issues that can emerge when justice considerations are taken or not taken into account in water governance. Water justice is particularly significant when societal change occurs because of altered allocations, institutional rules of the game or in the underlying hydrological regime. We summarise 10 steps that contribute to the continuing articulation of a ‘water justice framework’ by researchers interested in this field of research and practice.

Environmental flows are an integral component for the conservation and management of rivers, flood plains and other wetlands in the Murray–Darling Basin. Under the Basin Plan, environmental water is managed by the Commonwealth Environmental Water Office (CEWO) and the states. We assessed CEWO environmental flows (2014–15 to 2018–19), compared our findings with expected outcomes for vegetation in the Basin-wide Environmental Watering Strategy (EWS) and interviewed water managers about the efficacy of environmental watering. Some 21% of CEWO water was delivered as flood events, to 9 of 19 river valleys, inundating 7% of wetland area in those valleys annually and 0.8% of major Basin wetlands. A consistent pattern was the watering of many small wetlands on the South Australian Murray with small volumes (median area 43ha, volume 125ML). Just 12% of the area of river red gum subject to EWS expected outcomes was flooded, and half these events were likely suboptimal to achieve ecological benefits. Wetlands have not received the water they need and vegetation outcomes cannot be met by completion of the Plan in 2024. Rules that constrain flooding of private land must be relaxed if the Plan is to achieve its statutory requirement of wetland conservation.
