Politicisation of water use exacerbates farmers鈥 distrust
Researchers have found that in agricultural areas with declining resource availability, climate-adaptation risks increase when discussion about water allocation becomes politicised.

The finding was made through the examination of water management in the Langhorne Creek viticultural region, where researchers assessed the hydrosocial risk in 2021.
鈥淗ydrosocial risks arise from the social processes that influence, and are influenced by, human interactions with water,鈥 says Associate Professor Douglas Bardsley, from the University of Adelaide鈥檚 School of Social Sciences, who produced the study in association with colleagues Associate Professor Georgina Drew and Dr Bill Skinner.
鈥淭hese risks have become more prominent over the last twenty years due to increasing impacts of climate change and more extreme events, such as the Millennium Drought, which led to the over-use and depletion of some water resources.鈥
Langhorne Creek has a history of managing issues such as floods, over-use of groundwater, and increasing salinity in nearby water resources.
The region displayed an innovative attitude when managing these issues, which it achieved through excellent organisation, links to government, and by working together as a community.
鈥Strong engagement processes were initiated during the crisis of the Millennium Drought, and they led to some great hydrosocial processes,鈥 says Associate Professor Bardsley.
鈥淭his led to a range of innovations, such as new water infrastructure, agro-ecosystems and water recycling. People also organised and worked to prioritise the sustainability of water resource systems.鈥
However, the collaborative processes developed during this period did not last long term.
鈥淎fter the crisis passed, the processes were politicised by government, and technical solutions were prioritised over the important participatory approach that was developed earlier,鈥 says Associate Professor Bardsley.
鈥淭he outcome of this is now many landholders feel marginalised from water-resource science and decision-making.鈥
According to Associate Professor Bardsley鈥檚 research, which was , if the politicisation of hydrosocial processes occurs, communities experiencing hydrosocial risks could miss critical opportunities for climate adaptation.
鈥淲hat we saw during the Millennium Drought was landholders and other stakeholders recognising that limits needed to be placed on ground and surface water extraction,鈥 Associate Professor Bardsley says.
鈥淧lanning was therefore tolerated because it was well understood, and provided irrigators with confidence they could make long-term decisions around the new allocations.鈥
To ensure this type of outcome can be achieved, authentic engagement between science, policy and stakeholders should occur.
鈥淐urrently, future climate change projections are insufficiently incorporated into water planning,鈥 says Associate Professor Bardsley.
鈥淭here is an iterative process of updating allocations built into water planning, but long-term policy will need to increasingly incorporate future constraints in water resource availability.
鈥淚t is also important that effective scientific knowledge for water management is developed with strong processes alongside landholders so that everyone understands and supports the decisions that eventuate from that new knowledge.鈥
