This book explores the issue of salinization in the context of contemporary conflicts about irrigation, water, and the environment in Australia, considering the Murray-Darling Basin in particular. It provides an environmental and social history charting the transformation of rural communities in the basin through the salinization of soils and water. Focusing on the Goulburn-Murray Irrigation district in the southwest of the Murray-Darling basin – the largest irrigation district in Australia – it explores the history of state-directed, large-scale engineering in the district, where the environment has been altered dramatically to facilitate white agricultural settlement inland. Changes to the landscape led to extensive salinization, however – a significant environmental threat in Australia. This book traces the impact of these changes on rural communities, taking a ‘bottom-up’ approach, highlighting the connections between environmental, social, and political change. It provides an important reflection on the importance of environmental history for facing the challenges posed by anthropogenic climate change.
