Opportunities for reclaimed water use in Australian agriculture

This paper provides an overview of how Australia exploits its water resources with a focus on reclaimed water. Arguments are brought up for the high value horticultural sector (vegetables, fruits and grapes) being a competitive customer for reclaimed water. Factors to consider when assessing the suitability for reclaimed water use in horticulture either for substitution of existing water resources or expansion of production are discussed.

Australian adults’ knowledge of Australian agriculture

Purpose – Agriculture is a major generator of wealth and employment in Australia. However, it faces a range of economic and environmental challenges which require substantial community support. The purpose of this paper is to examine Australian adults’ Australian knowledge of, and attitudes towards, Australian agriculture. Design/methodology/approach – Online questionnaire survey of 1,026 adults conducted nationwide during August 2012. Findings – Most respondents had little knowledge of even the basic aspects of the industry but they approved of farmers’ performance of their roles. Latent class analysis showed that there are two groups of consumers with low and lower levels of knowledge. The respondents’ age, rural residence and universalist values were positive predictors of agricultural knowledge. Research limitations/implications – This was a cross-sectional, quota-based survey which examined only some aspects of agriculture. However, the findings suggest that more communication with the general public about the industry is required in order to build on the positive sentiment that exists within the community. Practical implications – More education about agriculture in schools and higher education is indicated. Social implications – The poor state of knowledge of agriculture threatens the social contract upon which agricultural communities depend for survival. Originality/value – The study highlights the poor state of general knowledge about agriculture in Australia. The findings could be used as a baseline against which the efficacy of future education programmes could be assessed.

Expert systems modeling for assessing climate change impacts and adaptation in agricultural systems at regional level

Australian agriculture is very susceptible to the adverse impacts of climate change, with major shifts in temperature and rainfall projected. In this context, this paper describes a research methodology for assessing potential climate change impacts on, and formulating adaptation options for, agriculture at regional level. The methodology was developed and applied in the analysis of climate change impacts on key horticultural commodities—pome fruits (apples and pears), stone fruits (peaches and nectarines) and wine grapes—in the Goulburn Broken catchment management region, State of Victoria, Australia. Core components of the methodology are mathematical models that enable to spatially represent the degree of biophysical land suitability for the growth of agricultural commodities in the region of interest given current and future climatic conditions. The methodology provides a sound analytic approach to 1) recognise regions under threat of declines in agricultural production due to unfolding climatic changes; 2) identify alternative agricultural systems better adapted to likely future climatic conditions and 3) investigate incremental and transformational adaptation actions to improve the problem situations that are being created by climate change.

Adaptation to climate change in regional Australia : a decision-making framework for modelling policy for rural production

A decision-making framework was developed and applied in regional Australia to identify adaptation issues arising in agricultural systems and rural production as a consequence of climate change. Australian agriculture is very susceptible to the adverse impacts of climate change, with major shifts in temperature and rainfall projected. An advantage of the framework is that it provides a suite of tools to aid in the formulation of strategies for sustainable regional development and adaptation. The decision-making framework uses a participatory approach that integrates land suitability analysis with uncertainty analysis and spatial optimisation to determine optimal agricultural land use (at a regional scale) for current and possible future climatic conditions. It thus provides a robust analytic approach to (i) recognise regions under threat of productivity declines, (ii) identify alternative cropping systems better adapted to likely future climatic conditions and (iii) investigate policy actions to improve the sub-optimal situations created by climate change. The decision-making framework and its methods were applied in a case study of the South West Region of Victoria.

The relationship between native vegetation and in-stream salinity: An Australian case study

The Glenelg-Hopkins area is a large regional watershed (2.6 million ha) in southwest Victoria that has been extensively cleared for agriculture. In-stream electrical conductivity (EC) in relation to remnant native vegetation is examined from the headwaters to the upper extent of the estuary of the Glenelg River. Five water quality gauging stations were selected. Their contributing subcatchments represent a continuum of disturbance. Proportions of native vegetation ranged from ∼100% at the headwaters of the river to ∼30% at the furthest downstream gauge station. The relationship between remnant vegetation and in-stream EC was examined using aggregated and non-aggregated land use statistics over a period of 22 years from three land use maps. Increased proportions of native vegetation were significantly negatively correlated with in-stream EC and were consistent across all scenarios investigated.

Temporal changes in macroinvertebrate assemblages following experimental flooding in permanent and temporary wetlands in an Australian floodplain forest

The River Murray, Australia, is a highly regulated river from which almost 80% of mean annual flow is removed for human use, primarily irrigated agriculture. Consequent changes to the pattern and volume of river flow are reflected in floodplain hydrology and, therefore, the wetting/drying patterns of floodplain wetlands. To explore the significance of these changes, macroinvertebrate samples were compared between permanent and temporary wetlands following experimental flooding in a forested floodplain of the River Murray. Weekly samples from two permanent wetlands and four associated temporary sites were used to track changes in macroinvertebrate assemblage composition. Non-metric multidimensional scaling was used to ordinate the macroinvertebrate data, indicating consistent differences between the biota of permanent and temporary wetlands and between the initial and later assemblages in the temporary sites. There were marked changes over time, but little sign that the permanent and temporary assemblages were becoming more alike over the 25-week observation period. The apparent heterogeneity of these systems is of particular importance in developing river management plans which are likely to change flooding patterns. Such plans need to maintain a mosaic of wetland habitats if floodplain biodiversity is to be supported.

The story of Australian agricultural economics 1900-1975

The growth of the agricultural economics profession in Australia is evaluated within the context of government policy. Particular economists and agricultural economists were instrumental in questioning the government's policy approach to agriculture. Their life work is assessed to ascertain their legacy to this country through their research, teaching and writing.

From despotism to democracy : reporting Iraq's January 2005 election in the Australian and Middle Eastern print media

It is only in recent times that the magnitude of Ancient Mesopotamia’s contribution to language, agriculture, modern thought and urbane society has begun to be understood. Most relevant to this study is the governance of Mesopotamia’s early city-states by a political system that Jacobsen has termed ‘Primitive Democracy’ where “…ultimate political power rested with a general assembly of all adult freemen” (Jacobsen, 1977; 128). Yet, despite this, the coverage of Iraq in the Western media since its creation at the end of the First World War and particularly since the first Gulf War, has tended towards Orientalism (Said, 1978) by trivialising this nation and thereby reinforcing the hegemony of the West over the ‘backward, barbaric’ East.

This paper examines this issue further by comparing and contrasting the representations of the Iraqi election of January 30, 2005 in four of Australia’s leading daily newspapers (The Australian, The Courier-Mail, The Age and The Sydney Morning Herald) with four Middle Eastern English language papers (The Daily Star from Lebanon, Andolu Agency and Dunya both based in Turkey, and the eponymous Kuwait Times). In essence, it finds that while the Australian media posits democracy as a Western concept and asserts a discourse of US hegemony, the Middle Eastern papers are more contemplative, focusing on the impact that this election could have throughout the region.
