Peri-urbanisation, Social Heterogeneity and Ecological Simplification
Peri-urban development pressure on and near Australian coastlines is resulting in the conversion of agricultural land for rural-residential use. The impact of larger and more diverse human populations upon the ecological assets remaining in agricultural landscapes has consequently become a policy concern. This paper contributes to these policy debates by integrating the results of parallel social and ecological research projects commissioned to improve natural resource management in peri-urbanising regions. The research was undertaken in the case study region of South East Queensland, the region supporting Australia’s most rapid population growth. Our results indicate that both social and ecological communities cross a fragmentation threshold due to peri-urban development whereby they become ecologically simple and socially heterogeneous in a coupling that cedes a poor diagnosis for biodiversity retention.stored soil water, dryland grain cropping, extension, social systems, RD&E, differentiation
The water-food-energy nexus in Pakistan: A biophysical and socio-economic challenge
We draw on previous work examining historical trends, likely future water use and food availability in Pakistan and extend the analysis to consider interactions with hydropower generation and the energy demand in food production due to pumping of groundwater for irrigation. Business-as-usual scenarios suggest growing demands for groundwater and energy use for food production as population grows rapidly. However, groundwater use is already unsustainable in many areas, and energy supply is failing to keep up with demand. Quantifying material linkages between water, food and energy provides a means to explore biophysical constraints. Characterising institutional constraints is equally important, as they can be significant barriers to effective stewardship of water, energy and food resources. The experience in Pakistan reinforces this finding, and we discuss the implications for hydrologists
Reflexive governance of urban catchments: A case of deliberative truncation
Integrated, collaborative governance arrangements are viewed as answering the limitations of the liberal, democratic state in the face of 'wicked' policy dilemmas such as environmental degradation. The nature of institutional resistance to governance experiments, however, has received limited attention. This paper explores a case of such resistance by the New South Wales political system: the decision to disband the Hawkesbury-Nepean Catchment Management Trust. This discontinuation of the administrative coordination and community engagement aimed at restoring the health of Sydney's major river system is herein characterised as a deliberative truncation. Discussion of what would constitute constructive ecological institutional and policy settings was cut short by intolerant notions of efficacy sustained by political/administrative routines. Analysis of this truncation is progressed through a nexus between three mutually informative theories of modernity dealing with the policy challenges facing liberal democratic societies today
The influence of agronomic advice upon soil water thresholds used for planting decisions in Southern Queensland's grains region
At least two decades of sustained research, development and extension (RD&E) effort was undertaken in Southern Queensland's broad acre cropping zone regarding the role of stored soil water in crop performance. Grain industry concern that the resulting insights into stored soil water were not being integrated into the planting decisions of grain producers was raised when a series of dry years culminated in widespread wheat crop failure across Southern Queensland's Darling Downs in the winter of 2007. This paper reports on a resulting qualitative investigation into the use of stored soil water research in planting decisions in this cropping region of Australia. A dual sample of grain producer and agronomic RD&E advisors were interviewed in-depth in order to establish what planting strategies were used by grain producers, explore the relationship between these strategies and agronomic advice, as well as the relationship between grain grower's planting decisions and their short and long term economic objectives. We found that all of the interviewees understood the role of stored soil water in crop performance. However, this understanding supported three distinct planting decision strategies: plant only when a stored soil water threshold has been reached; take the opportunity to plant at least some crop each season; and plant at the appropriate time to maximise crop yield and consider stored soil water a bonus. These planting strategies were perceived by the interviewees to be aligned to agronomic advice differentiated by its commercial terms. Private agronomists, hired via an annual retainer, tended to be associated with the first planting strategy while retail agronomists, hired through the purchase of chemicals, were perceived as associated with the second strategy. These results indicate that an industry wide comparison of planting strategies in terms of yield outcomes and economic performance over multiple years is warranted in order to facilitate industry wide discussion of the trade-offs between long term enterprise profitability and short term economic pressures.Plant available water Dryland grain cropping Extension Social systems RD&E
Democracy, consultation and socio-environmental degradation : diagnostic insights from the Western Sydney/Hawkesbury-Nepean region
The use of community consultation to address socio-environmental degradation is entwined with contested democratic principles polarising views of its role. I frame this problem by examining three democratic paradigms faced with two contemporary problems. The deliberative argument that preferences require enrichment with debate mediates between the liberal-aggregative view that preferences are individual, private and amenable to aggregation and the view that participation in public life is foundational. Viewing consultation as deliberative reconciles the liberal-aggregative view of consultation as the illegitimate elevation of unrepresentative minority groups with the participationist view that consultation constitutes a step towards participatory democracy. Theorists of social reflexivity, however, point to an elided politics of knowledge challenging technoscience's exemption from politically garnered consent. Also neglected by much democratic theory is how functional differentiation renders self-referential legal, political, technoscientific and administrative domains increasingly unaccountable. I employ Habermas' procedural theory that public spheres allow social irritations into the political domain where they can be encoded into laws capable of systemic interjection in response, along with a dialogic extension accommodating the politics of knowledge. I then use this procedural-dialogic deliberative understanding of democracy to elucidate the context and outcomes of the NSW State's consultative strategy. The NSW state, institutionally compelled to underwrite economic growth, implicating itself in that growth's socio-environmental side effects provoking widespread contestation. The resulting Environmental Planning and Assessment Act (1979) and its adjunctive consultative provisions helped highlight the socio-environmental degradation of the Hawkesbury Nepean River Catchment via Western Sydney's urban sprawl, politicising the region. The convenement of a consultative forum to oversee a contaminated site audit within the region facilitated incisive lay critique of the technoscientific underpinnings of administrative underwriting of socio-environmental degradation. The discomforted NSW State tightened environmental policy, gutted the EP&A Act's consultative provisions and removed regional dialogic forums and institutions. I conclude that the socio-economic accord equating economic growth with social progress is both entrenched and besieged, destabilising the political/administrative/technoscientific regime built upon it. This withdrawal of avenues for critique risks deeper estrangement between reflexive society and the NSW State generative of electoral volatility
