The flush toilet is an illogical form of sanitation from the point of view of water conservation, nutrient recovery and water pollution. Places such as London, with one of the oldest flushing toilet and sewer systems in the world, bears witness to the limits of its universal applicability through dwindling freshwater resources and polluted waterways. It is therefore important to develop new forms of sanitation infrastructure. An actor–network theory coevolution framework is used to explore and gain insights into the coevolution pathways for new types and paradigms of sanitation in London, where waterborne sanitation is currently prevalent. This approach shows that while flushing toilets are currently stable network configurations, there are coevolution pathways that would shift the system towards dry sanitation. The quantity of freshwater resources available for toilet flushing was the main actant cited for the development of these coevolution pathways. 相似文献

An assessment of floodplain regulation by the Upper Thames River Conservation Authority in the City of London for the period
1978–1989 was undertaken. Utilizing a mix of data sources available through the conservation authority office, questionnaires
administered to flooplain residents, interviews with relevant government officials, and housing statistics, the study concludes
that regulations have been administered in an equitable and efficient manner. However, regulations have had some problems
in controlling all development activity and in addressing policy objectives. Problems arise from weaknesses in the Conservation
Authorities Act, an ensuing lack of judicial and participating municipal support in prosecuting violations, and inadequate
monitoring and enforcement of development activity. Without addressing these issues, the basic problems associated with floodplain
management in Ontario will remain. 相似文献

Intensification of existing urban areas is currently a major item on the policy agenda of the Ontario and Canadian governments. As part of the urban intensification drive, brownfield sites have become major candidates for redevelopment. Governments at all levels have initiated policies and programmes to encourage their remediation and redevelopment. This paper reports the findings of a qualitative exploration of brownfield redevelopment in London, Canada. Through in-depth interviews (n?=?17) with key stakeholders involved in brownfield redevelopment, the study explores the level of participation in brownfield redevelopment, barriers to brownfield redevelopment in the city, and perceptions about financial incentives in the city's Brownfield Community Improvement Plan. The study found that despite the availability of financial incentives, the overall private sector participation in brownfield redevelopment is low due to barriers such as competition from greenfield, risk, cost, negative public perception of brownfields, and complex remediation processes. The paper provides policy suggestions that may contribute to a more active participation in brownfield redevelopment in the city. 相似文献
