What if Edward Abbey's “Monkey Wrench Gang” had Succeeded? The Ghosts of Glen Canyon Past,Present, and Future

Across the fiction and non‐fiction writings of Edward Abbey (1927–1989), the anticipated restoration of Glen Canyon on the Colorado River is a recurring theme. This article employs Abbey's polemic for the removal of Glen Canyon Dam to critique contemporary debates on dam decommissioning, water politics, and ecological restoration in Glen Canyon on the Utah–Arizona border. The endeavours (and fantasies) of Abbey's fictional quartet of eco‐saboteurs reveal his radical and anarchical imaginings on how to remove the dam, yet his non‐fiction works often suggest why Glen Canyon should be restored. The politicisation of Abbey's philosophy is explored through (1) organisational, institutional responses to the question of draining Lake Powell reservoir and decommissioning the dam, and (2) how the ideology of Abbey's fictional gang is recast—and plays out—in the actions of environmental activists. This article argues that Abbey remains an important voice in the battle to restore the Glen.     

From Traditional Farming in Morocco to Early Urban Agroecology in Northern Mesopotamia: Combining Present-day Arable Weed Surveys and Crop Isotope Analysis to Reconstruct Past Agrosystems in (Semi-)arid Regions

ABSTRACT

We integrate functional weed ecology with crop stable carbon and nitrogen isotope analysis to assess their combined potential for inferring arable land management practices in (semi-)arid regions from archaeobotanical assemblages. Weed and GIS survey of 60 cereal and pulse fields in Morocco are combined with crop sampling for stable isotope analysis to frame assessment of agricultural labour intensity in terms of manuring, irrigation, tillage and hand-weeding. Under low management intensity weed variation primarily reflects geographical differences, whereas under high management intensity fields in disparate regions have similar weed flora. Manured and irrigated oasis barley fields are clearly discriminated from less intensively manured rain-fed barley terraces in southern Morocco; when fields in northern and southern Morocco are considered together, climatic differences are superimposed on the agronomic intensity gradient. Barley δ¹³C and δ¹⁵N values clearly distinguish among the Moroccan regimes. An integrated approach combines crop isotope values with weed ecological discrimination of low- and high-intensity regimes across multiple studies (in southern Morocco and southern Europe). Analysis of archaeobotanical samples from EBA Tell Brak, Syria suggests that this early city was sustained through extensive (low-intensity, large-scale) cereal farming.     

Modelling Uncertainties of Italian Code-Conforming Structures for the Purpose of Seismic Response Analysis

ABSTRACT

This paper describes the multivariate statistical model of the structure-related modelling uncertainty, developed with reference to reinforced concrete, masonry, steel, and seismically isolated buildings, within the framework of the RINTC project. The model describes the variability of material properties as well as the uncertainty associated with the adopted response models. Specific aspects of each structural typology are also discussed, with a focus on the statistical dependence of the random variables in the model. Finally, the paper describes also the efficient sampling procedure adopted. Effect of model uncertainty on response for each typology are discussed in the corresponding papers within this special issue dedicated to the RINTC project.     

Seismic behavior of two Portuguese adobe buildings: part II —numerical modeling and fragility assessment

Considering the likely unfavorable behavior under seismic action of adobe construction, this article aims at providing a seismic fragility characterization of two adobe Portuguese traditional buildings, using numerical models calibrated over experimental results. The study of such two case-study buildings in the region of Aveiro contributes to the understanding of the seismic fragility of adobe construction in the region in general. The buildings were numerically modeled to estimate their structural behavior under seismic loading using adobe material properties that were calibrated based on the experimental results of a cyclic in-plane test of a full-scale double-Tshaped adobe wall. The method chosen to characterize adobe masonry and model its nonlinear behavior followed a total strain crack-based macro-modeling (TSCM) approach, whereas pushover analysis was carried out to reproduce the pseudo-static experimental test in order to enable a refined calibration of adobe masonry mechanical properties. Fragility functions were then derived, based on the above-mentioned numerical models, using nonlinear static analysis, bringing further insight on the seismic fragility of traditional Portuguese adobe construction.     

Socialist architecture as today’s dissonant heritage: administrative buildings of collective farms in Estonia

The heritage studies of the socialist built legacy of the former Soviet Socialist Republics have mainly concentrated on the buildings and monuments representing the political ideology of the socialist era due to their evidently controversial character, while the more mundane and ordinary legacy has seldom been the focus. The administrative buildings of collective farms represent a particular socialist architecture of the 1960s–1980s in Estonian rural areas and small towns. These prosaic buildings, which used to play important role in the Soviet-time rural life, have become a dissonant heritage today, although their controversial nature lies in the complicated contemporary environment they fell into after the collapse of the socialist regime, rather than in the fact that they were constructed for ideological purposes. This paper examines the dissonant processes and the present contexts that affect the re-use and preservation of the administrative buildings of collective farms, as well as the acceptance of them as a meaningful part of Estonian history that should not be ignored or forgotten.
