Local perception of a regulatory order Closing down an abstraction point as a crisis indicator?

The closure of a drinking water catchment and deterioration of water quality raise questions about concepts such as water quality and territory. This prompts us to consider the interactions between resource and environmental policy, insofar as sensitivity to the standard of water used for human consumption is high and where its operation involves a large number of actors: state departments, public managers and private firms, land and water users and their representatives. Investigations by semi-directive interviews and surveys were conducted with users and water managers at three sites in Brittany (Finistère and in Ille-et-Vilaine) affected directly or indirectly by the Grenelle 1 bill. The results of the survey suggest that the crisis, if it exists, is attributed by the actors to the quantitative evolution of the resource and to regulations perceived as arbitrary in a context of poorly-controlled environmental dynamics. The socio-economic obstacles to quality improvement are frequently advanced in discussions, but management policies capable of removing these obstacles are very rarely mentioned. Instead, the stakeholders place their trust in technological solutions and work towards the political construction of functional solidarities.

Space matters: the importance of amenity in planning metropolitan growth

Most Australian capital cities require many 100,000s of additional dwellings to accommodate demographic change and population pressures in the next two or three decades. Urban growth will come in the form of infill, consolidation and urban expansion. Plans to redevelop environmental amenities such as parks and open green spaces are regularly being put forward to local councils and State governments. Maintaining parks and reserves represents one of the largest costs to local councils. To aid in the evaluation of some of the different propositions, we report the results of a spatial hedonic pricing model with fixed effects for Adelaide, South Australia. The results indicate that the private benefits of a close proximity to golf courses, green space sporting facilities, or the coast, are in the order $0.54, $1.58, and $4.99 per metre closer (when evaluated at the median respectively). The historic Adelaide Parklands add $1.55 to a property’s value for each additional metre closer. We demonstrate how the estimated model could be used to calculate how local private benefits capitalized in property values change with changes in the configuration of a park.
