State rescaling and new metropolitan space in the age of austerity. Evidence from Italy

This article presents the changes that are emerging in the Italian national policies mainly through the discussion of the contents both of the recent metropolitan reform initiative, and the national programming documents for metropolitan cities related to European Programming period 2014–2020. In Italy, which faced severe political difficulty and economic stagnation after 2008 global crisis, the production of the new metropolitan scale became one of the tools for the implementation of austerity measures. The paper examines whether the understanding of the new metropolitan scale in the Italian geography of austerity can be strengthened through a careful engagement with the body of literature on state rescaling and on austerity policies. The paper illustrates how that the apparently neutral emphasis on metropolitan city scale, first can be understood as a crucial tool of an austerity measures; second, it implies a rescaling of public power and, third, it neglects the multifaceted notion of the urban and the trans-scalar territorial governance relationships.

South Australian geology and the State Heritage Register: an example of geoconservation of the Naracoorte Caves complex and karst environment

South Australia’s State Heritage Register contains 2294 listed places, the majority of which are from the ‘Built’ environment, ranging from settlers’ huts, community buildings, historical industrial sites to magnificent stone mansions. Only 96 places are linked to the ‘Natural’ environment. The Register listings protect heritage places from alteration, damage or removal without formal prior consultation, compulsory under the South Australian Development Act. ‘Natural’ environments are landscape-based and oriented towards Geological, Archaeological, Palaeontological and Speleological heritage (‘GAPS heritage’). A process to provide a greater balance between ‘Natural’ and ‘Built’ listings has initiated a series of State Heritage ‘Natural’ environment assessments, mostly of single sites. Two individual caves in the Naracoorte Caves National Park are already entered in the State Heritage Register as single sites. However, an innovative broader multiple-site nomination has focused on the many different but significant GAPS features contained within the 25 caves of the Naracoorte Caves National Park, providing a further level of protection for the land and the caves’ exteriors and interiors. The example of the Naracoorte Caves draws attention to the number of important land and coastal karst (limestone) features across South Australia that were generated by steady geological uplift of three large sections of Oligocene–Miocene limestone—the Nullarbor Plain, the Murray Basin and the Gambier Karstfield (which includes Naracoorte and Mount Gambier), resulting in specific karst forms worthy of a broader coordinating management approach across South Australian karst parks.     

“Love for sale”: Biodiversity banking and the struggle to commodify nature in Sabah,Malaysia

In Malaysia, second largest palm oil producer worldwide, logging companies, palm oil corporations, and even responsible citizens can now compensate their biodiversity impacts by purchasing Biodiversity Conservation Certificates in an emerging new biodiversity market: the Malua BioBank. Biodiversity markets are part of a wider trend of marketisation and neoliberalisation of biodiversity governance; introduced and promoted as (technical) win–win solutions to counter biodiversity loss and enable sustainable development. The existing neoliberalisation and nature literature has tended to analyse these processes as consequences of an inherent drive of capital to expand accumulation and submit ever more areas of nature to the neoliberal market logic.In contrast, I aim (a) to problematise the agency and the “work” behind marketisation of biodiversity, challenging the story of (corporate-driven) neoliberalisation as the realisation of an inherent market-logic (based on the a false conceptual state–market divide, often prevalent even in activist academic circles working on neoliberalisation of nature) and to see the state not only as regulator, but driving force behind, and part of “the market”; (b) to question the myth of neoliberalisation as state losing control to the market and to show how the state is using the biodiversity market as mode of governing; re-gaining control over its forests and its conservation policy; and (c) to demonstrate empirically the distinction between neoliberal ideology and practice, and to show that marketisation was based on pragmatic decisions, not ideology-driven political action. My analysis is based on 35 qualitative interviews with actors involved in the BioBank.     

Interpretation of seismic and potential field data from western New York State and Lake Ontario

Lithoprobe and industry seismic profiles have furnished evidence of major zones of easterly dipping Grenville deformed crust extending southwest from exposed Grenville rocks north of Lake Ontario. Additional constraints on subsurface structure limited to the postulated Clarendon–Linden fault system south of Lake Ontario are provided by five east–west reflection lines recorded in 1976. Spatial correlations between seismic structure and magnetic anomalies are described from both Lake Ontario and the newly reprocessed New York lines.In the Paleozoic to Precambrian upper crust, the New York seismic sections show: (1) An easterly thickening wedge of subhorizontal Paleozoic strata unconformably overlying a Precambrian basement whose surface has an apparent regional easterly dip of 1–2°. Minor apparent normal offsets, possibly on the order of tens of meters, occur within the Paleozoic section. The generally poorly reflective unconformity may be locally characterized by topographic relief on the order of 100 m; (2) Apparent local displacement on the order of 90 m at the level of the Black River Group diminishes upward to little or no apparent offset of Queenston Shale; (3) Within the limited seismic sections, there appears to be no evidence that the complete upper crustal section is vertically or subvertically offset; (4) Dipping structure in the Paleozoic strata (15° to 35°) resembles some underlying Precambrian basement elements; (5) The surface continuity of inferred faults constituting the Clarendon–Linden system is not strongly supported by the seismic data.Beneath the Paleozoic strata, the seismic sections show both linear and arcuate reflector geometry with easterly apparent dips of 15° to 35° similar to the deep structures imaged on seismic lines from nearby Lake Ontario and on Lithoprobe lines to the north. The similarity supports an extension of easterly dipping Central Metasedimentary Belt structures of the Grenville orogen from southern Ontario to beneath western New York State.From a comparison of the magnetic and gravity fields with the New York seismic sections, we suggest: (1) The largely nonmagnetic Paleozoic strata appear to contribute negligibly to magnetic anomalies. Seismically imaged fractures in the New York Paleozoic strata appear to lie mainly west of a positive gravity anomaly. The relationship between magnetic and gravity anomalies and the changes in the geometry of interpreted Precambrian structures remains enigmatic; (2) North to northeast trending curvilinear magnetic and gravity anomalies parallel, but are not restricted to the principal trend of the postulated Clarendon–Linden fault system. Paleozoic fractures of the Clarendon–Linden system may partly overlie a southward extension of the Composite Arc Belt boundary zone.     

Geochemical characterization of heavy metal contaminated area using multivariate factorial kriging

This paper describes a geostatistical method, known as factorial kriging analysis, which is well suited for analyzing multivariate spatial information. The method involves multivariate variogram modeling, principal component analysis, and cokriging. It uses several separate correlation structures, each corresponding to a specific spatial scale, and yields a set of regionalized factors summarizing the main features of the data for each spatial scale. This method is applied to an area of high manganese-ore mining activity in Amapá State, North Brazil. Two scales of spatial variation (0.33 and 2.0 km) are identified and interpreted. The results indicate that, for the short-range structure, manganese, arsenic, iron, and cadmium are associated with human activities due to the mining work, while for the long-range structure, the high aluminum, selenium, copper, and lead concentrations, seem to be related to the natural environment. At each scale, the correlation structure is analyzed, and regionalized factors are estimated by cokriging and then mapped.     

Cyclic liquefaction screening of sand with non-plastic fines:Critical state approach

There have been significant advances in the application of critical state,CS,in liquefaction potential assessment.This was done by comparing state parameter,j with estimated characteristic cyclic stress ratio,CSR due to an earthquake.A cyclic resistance ratio,CRR curve,which can be determined from cyclic liquefaction tests,separates historical liquefied and non-liquefied data points(j,CSR).On the other hand,the concepts of equivalent granular state parameter,j*,which was developed for sands with fines,can be used in lieu j to provide a unifying framework for characterizing the undrained response of sands with non/low plasticity fines,irrespective of fines content(fc).The present work combines these two propositions,and by merely substituting j*for j into the aforementioned CS approach to capture the influence of fc.A series of static and cyclic triaxial tests were conducted,separately and independently of the concept of j*,for sand with up to fc of 30%.The clean sand was collected from Sabarmati river belt at Ahmedabad city in India which was severely affected during the Bhuj earthquake,2001.The experimental data gave a single relation for CRR and j*which was then used to assess liquefaction potential for a SPT based case study,where fc varies along the depth.The prediction matched with the field observation.     

A constitutive model for sand based on non-linear elasticity and the state parameter

The paper describes the development of a constitutive model for a poorly graded sand, which was used in geotechnical experiments on buried pipes (reported elsewhere). The sand was tested extensively in the laboratory to determine the state parameter constants. Triaxial tests on the sand included conventional drained triaxial compression tests, as well as more specialized shearing tests at constant mean effective stress and others at constant volume. Single element simulation of the triaxial tests was performed to validate the proposed constitutive model. The adopted model allowed non-linear elastic behaviour prior to yielding. After yielding of the sand, the state parameter-based model for the sand permitted non-associated plastic flow. Dilation and frictional strength were both dependent on the current value of the state parameter. The combination of laboratory testing and single element modelling resulted in the selection of a single set of material constants for the soil, which adequately described the full range of triaxial tests. Subsequently the model was applied to the problem of a plate loading test on the sand and the model predictions were compared with the test data.
