Don’t abhor your neighbor for he is a pastoralist: the GIS-based modeling of the past human–environment interactions and landscape changes in the Wadi el-Hasa,west-central Jordan

Recently developed modules in GRASS GIS combine a wide variety of spatial data such as climatic, geological, and cultural in order to estimate how long-term interactions among these factors contribute to the evolution of natural environment and anthropogenic landscapes. Additionally, these modules allow users to visualize anthropogenic impacts of extensive agropastoralism on landscapes by subjecting the pre-defined catchment areas to repeated land use activities. The results emphasize the economic and ecological value of extensive agropastoralism in the marginal landscapes, which make anthropogenic activities more sustainable in the long-term. The results of this research are not only significant for its methodological contributions in anthropological archaeology but also have broader significance for researchers interested in interdisciplinary approaches in assessing the long-term dynamics of human-environment relations.     

Green cities? Urbanization,trade, and the environment

Is urbanization good for the environment? This paper establishes a simple core–periphery model with monocentric cities, which comprises key forces that shape the structure and interrelation of cities to study the impact of the urban evolution on the environment. We focus on global warming and the potential of unfettered market forces to economize on emissions. The model parameters are chosen to match the dichotomy between average “large” and “small” cities in the urban geography of the United States, and the sectoral greenhouse gas emissions recorded for the United States. Based on numerical analyzes we find that a forced switch to a system with equally sized cities reduces total emissions. Second, any city driver which pronounces the asymmetry between the core and the periphery drives up emissions in the total city system, too, and the endogenous adjustment of the urban system accounts for the bulk of the change in emissions. Third, none of the city drivers gives rise to an urban environmental Kuznets curve according to our numerical simulations. Finally, the welfare‐maximizing allocation tends to involve dispersion of cities and the more so the higher is the marginal damage from pollution.     

Precarious foundations: irrigation,environment, and social change in the Canadian Pacific Railway's Eastern Section, 1900–1930

This paper analyzes the introduction and development of irrigation agriculture in the lower Bow River region, Alberta, Canada. Sponsored by the Canadian Pacific Railroad (CPR) and the Canadian federal government, irrigation promised to transform semi-arid prairie into a densely settled countryside. After 1900, a mixture of policies and practices pioneered elsewhere were deployed to create the largest irrigation project of its kind in North America. Settlers faced difficult economic conditions, however, and fell into conflict with the CPR. The system as a whole experienced a range of environmental changes as irrigation water altered the land and produced new conditions for flora and fauna. By 1930, the irrigation project experienced high levels of settler abandonment and deep fiscal problems. The circumstances of the Bow River case suggest the particular qualities of social and environmental changes initiated by irrigation agriculture in the Canadian prairies, but they also provide the basis to consider comparatively the processes and difficulties attending irrigation expansion in the late nineteenth and early twentieth century world.     

Human–environment interactions in medieval Poland: a perspective from the analysis of faunal stable isotope ratios

Stable isotope analyses of faunal remains provide valuable information about human–environment interactions in the past, including insights into past animal husbandry and land management strategies. Here, we report stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope values of collagen and carbonate from archaeological fauna from Ka?dus, a medieval settlement in North-Central Poland, to better understand human–environment interactions during a period of increasing urbanism and marketization. Wild and domestic animals can be separated on the basis of their isotopic values. The mean δ¹⁵N value for 12 domesticated animals is 7.6 ± 1.2‰ and for 5 wild animals is 4.3 ± 0.5‰ (p = 0.002). The mean collagen δ¹³C value for domesticated animals is −20.6 ± 1.1‰ and for wild animals is −22.0 ± 0.5‰ (p = 0.004). The mean carbonate δ¹³C value for domesticated animals is −13.14 ± 1.3‰ and for wild animals is −14.14 ± 0.9‰ (p = 0.034). The “canopy effect” and anthropogenic effects that alter stable isotope ratios of plants (manuring, swidden agriculture and ploughing) are discussed in relation to these differences. Fish are isotopically variable, which suggests broad-spectrum fishing strategies and/or trade, and increases our awareness of the difficulties in interpreting human paleodiet when freshwater fish were on the menu.     

The other cold war: the United States and Greenland’s ice sheet environment, 1948–1966

During the early Cold War, no part of the Arctic was as important to the United States’ strategic interests as Greenland: situated on the shortest straight-line route between the industrial centers of the two superpowers, Greenland was integral to North American continental security. The US desire to control Greenland, however, was complicated by the island’s isolated geography, harsh climate and barren landscape. Between 1948 and 1966, US forces in Greenland were entrenched in the ‘other cold war’: the struggle with the ice sheet environment which threatened to impede American capabilities in the region. This paper explores the ‘other cold war’ through two case studies: US scientific efforts to understand and cope with polar whiteouts and the plastic deformation of ice. These case studies illuminate a struggle between two philosophical approaches to nature: a brash, aggressive approach which aimed to conquer the Greenland environment, and a more nuanced approach which aimed to collaborate with that environment. I show that the second approach won out as Greenland’s exceptional geography and environment forced the US military to reassess its relationship with nature: rather than striving for control over the island space, US military personnel ultimately chose strategic cooperation with that space.     

Doctoral dissertations in human geography from Swedish universities 1884–2015: demographics,formats and productivity

The doctoral dissertation is a key component of postgraduate education that plays an important role for knowledge production and hence the development of a discipline. Swedish human geography currently lacks an overview of dissertations. This article fills this knowledge gap by reporting findings from a unique database covering all doctoral dissertations between 1884 and 2015. The paper focuses on the demographics of the authors (age, gender), the format of the dissertation and explores productivity variations for authors of compilation dissertations. The findings show a notable increase in the number of doctoral dissertations since the late 1960s but a decreasing share of doctoral dissertations in the social sciences since the 1970s. In terms of demographics, we show that while the age of the authors remains relatively stable, the gender-balance has improved considerably. In terms of format, the monograph has rapidly given way to compilation dissertations, which now account for half the number of dissertations. More than 70% of all dissertations are now published in English. Statistical results suggest that the likelihood of completing a compilation dissertation is greater if the doctoral candidate is young and if attending Umeå University. But individual author productivity for compilation dissertations is mainly influenced by unobservables.     

Time,temporality, and woman–child relations

This is the second in a series of Viewpoints about a symposium on the intersections and antagonisms between various forms of feminism and the politics of childhood. This article traces the various ways in which time and temporality were mobilised in symposium papers and discussions and considers the implications for efforts to conceptualise woman–child relations. In conclusion, the potentials and risks of focusing on temporality when theorising relations between those positioned as women and those positioned as children are considered.
