Sustainable development, rolled-out neoliberalism and sustainable communities

Recent contributions by geographers on the relationships between states and citizens have documented the rise of rolled-out neoliberalism. Development agendas are, it is argued, increasingly dominated by the principles of market-driven reforms, social inequality, and a drive towards enhancing the economic competitiveness of the supply side of the economy. However, at the same time, a parallel set of discourses has emerged in the development literature which argues that it is principles of sustainable development that have, in practice, become dominant. The emphasis is, instead, on democratic empowerment, environmental conservation, and social justice. This paper examines the relationships between these ostensibly very different interpretations of contemporary development with an assessment of one of the Labour government's most ambitious planning agendas-the publication in February 2003 of the document Sustainable Communities: Building for the Future. The proposals are promoted as a "step change" in the planning system with a new emphasis on tackling shortages of housing in the South East and reviving the economy of the Thames Gateway area. The paper assesses the different ways in which such programmes can be interpreted and argues that contemporary development practices in countries such as Britain are constituted by a hybridity of approaches and rationalities and cannot be reduced to simple characterisations of rolled-out neoliberalism or sustainable development.

Eddy current testing system with scanning probe head having parallel and normal sensing coils

An eddy current testing system consists of a multi-sensor probe, a computer and a special expansion card and software for data-collection and analysis. The probe incorporates an excitation coil, and sensor coils; at least one sensor coil is a lateral current-normal coil and at least one is a current perturbation coil.

Extinction processes in hot spots of avian biodiversity and the targeting of pre-emptive conservation action

Hot spots of endemism are regarded as important global sites for conservation as they are rich in threatened endemic species and currently experiencing extensive habitat loss. Targeting pre-emptive conservation action to sites that are currently relatively intact but which would be vulnerable to particular human activities if they occurred in the future is, however, also valuable but has received less attention. Here, we address this issue by using data on Endemic Bird Areas (EBAs). First, we identify the ecological factors that affect extinction risk in the face of particular human activities, and then use these insights to identify EBAs that should be priorities for pre-emptive conservation action. Threatened endemic species in EBAs are significantly more likely to be habitat specialists or relatively large-bodied than non-threatened species, when compared across avian families. Increasing habitat loss causes a significant increase in extinction risk among habitat specialists, but we found no evidence to suggest that the presence of alien species/human exploitation causes a significant increase in extinction risk among large-bodied species. This suggests that these particular human activities are contributing to high extinction risk among habitat specialists, but not among large-bodied species. Based on these analyses, we identify 39 EBAs containing 570 species (24% of the total in EBAs) that are not currently threatened with severe habitat loss, but would be ecologically vulnerable to future habitat loss should it occur. We show that these sites tend to be poorly represented in existing priority setting exercises involving hot spots, suggesting that vulnerability must be explicitly included within these exercises if such sites are to be adequately protected.
