Challenges in managing dryland rivers crossing political boundaries: lessons from Cooper Creek and the Paroo River, central Australia

Abstract

1. Dryland rivers are a focal point of life. Highly variable flows that underpin the ecology of these rivers are the antithesis of requirements for regular water for irrigation. Proposals exist to divert water for irrigation on the dryland rivers, Cooper Creek and the Paroo River in central Australia, that cross political boundaries of three Australian states (Queensland, South Australia and New South Wales). 2. Poorly‐planned water resource developments on dryland rivers incur unacceptably high ecological costs. Debate about the future of Cooper Creek and the Paroo River is challenging traditional political accountabilities for management hitherto focused on land rather than water. Diversion of water for irrigation threatens high conservation values of these unregulated rivers and livelihoods of rural communities who rely on floods. The current process whereby a Government water agency in one political jurisdiction assesses and judges the merits of proposals that have ecological consequences is restrictive. We critique current mechanisms for assessment, and approval of proposals to divert water from dryland rivers in Australia. 3. An alternative is to begin with a discussion of the impacts of such proposals and ecological and social values under threat that involves a ‘collaborative’ resource management partnership between scientists, landholders and conservationists. Two scientific workshops on Cooper Creek and the Paroo River distilled such a process. This paper reviews the background to these workshops and their importance for decisions on sustainable management of dryland rivers and their floodplain wetlands. Scientific workshops involve the wider community in decision‐making that is traditionally the province of water managers and developers. Transparency, independence and a catchment focus remain challenges for decision‐making on the Paroo and the Cooper but the foundations were laid by the workshops. © 1998 John Wiley & Sons, Ltd.

Lake Eyre Basin Rivers

“…Concern is particularly acute in the desert channels environment of south-western Queensland where rivers are currently unregulated; their flood waters cover extensive areas that connect waterholes, lakes and wetlands after heavy rainfall , and the ephemeral pulses of productivity that they generate support livestock grazing (see chapters 10 and 11) and highly diverse native plants, animals and other organisms (Robin et al 2010; see Chapter 1). A coalition of groups fought successfully against plans to introduce irrigated cotton farming to the region in the mid-1990s because of the probable impacts on production and biodiversity values (Kingsford et al 1998). Proposals to increase water extraction for mining and irrigation have continued (see Chapters 19 and 20), with the region potentially less able to resist powerful corporate interests that are well served by the Regional Planning Interests Act 2014.…”

Aquatic ecosystems in inland Australia: tourism and recreational significance, ecological impacts and imperatives for management

“…These findings suggest that the condition of inland waterbodies is not only threatened by broad-scale land uses such as agriculture, pastoralism and mining (e.g. Smith 1998;Yencken and Wilkinson 2000;Aplin 2002) and the effects of water extraction and regulation for irrigation (Kingsford et al 1998;Sheldon et al 2002), but also from visitor activities at focal waterbodies arising from tourism and recreation.…”

Long-term environmental trends and the future of tropical wetlands

“…The ecological integrity of wetlands, however, depends on integrated forms of watershed management that in semi-arid regions may encompass large areas and many stakeholders who are not directly related to the wetlands. Integrated management requires the cooperation of all stakeholders in the catchment area who have to renounce some of their benefits in favour of sustainable use of the resources by all members of the community and environmental protection, as shown for Australian dryland rivers (Kingsford et al 1998). This integration requires a high level of understanding of ecological and socioeconomic interactions that scarcely exists in most countries.…”
