Geochemical evidence for the manufacture,logistics and supply‐chain management of Emperor Qin Shihuang's Terracotta Army,China

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce .     

Refugee Shelter in a Logistical World: Designing Goods for Supply‐Chain Humanitarianism

Focusing on the design and production of the IKEA Foundation “Better Shelter” and on its use in a camp on the island of Lesvos, Greece, this article explores the role of logistical calculative rationales in the provision of emergency shelters to refugees. It argues that an engagement with the critical geographies of logistics contributes to the study of such “humanitarian goods” in two main ways. First, it foregrounds the technologies that allow emergency shelter products to circulate across production sites and disaster and border zones, and their connections to broader infrastructures and commercial networks in what recent literature has called “supply‐chain humanitarianism”. Second, a logistical lens highlights the disruptions that characterise the production and usage of emergency shelter products. The analysis adds to a body of work that exposes humanitarian technology and design as sites of friction, deeply embedded in global processes of bordering and accumulation.     

Identifying pre-Hispanic water storages in agricultural areas of south-central Andes through diatom evidence

In the Andes, there are several pre-Hispanic irrigation networks with structures destined for water storage. However, it has not been widely discussed in archaeological research. This is probably due to their being difficult to identify. The aim of this study is to explore the use of diatom assemblage analysis as a methodological tool suitable to help in the identification and characterization of these ancient hydraulic structures. We analyzed two archaeological structures interpreted as water reservoirs from north-western Argentina (EH1 in Antofagasta de la Sierra and U-88R1 in Yocavil) and compared them to current reservoirs. The diatom species composition and the changes in the dominant ecological groups in the studied structures highlight different periods of hydraulic behavior. EH1 contained and stored water, but there were periods of time in which there was a lack of use or abandonment of the structure. However, the U88-R1 structure does not have diatom evidence of containing standing water for a prolonged time but presence of wet soils. Thus, the structure could have been used for other water management strategies. The results show that diatom analysis is a methodological tool with a high potential to study ancestral hydrotechnologies.     

Inter- and intraregional inequality in a spatial economy

In this paper, we develop a three-region economic geography model with workers of heterogeneous skills and mobility rates to consider how first-nature, regional differences impact both inter- and intraregional inequality. In our model, the skill premium within a region summarizes both the degree of intraregional inequality between mobile, skilled workers and immobile, unskilled workers and the interregional inequality through differences in the welfare of unskilled workers across regions. Regions with the highest skill premium have the greatest degree of intraregional inequality and provide the lowest level of welfare to unskilled workers, relative to other regions. We find that the skill premium will be higher in regions with a greater supply of unskilled labor, lower supply of housing, or are more remote. An increase in a region's housing supply or centrality will lower intraregional inequality and raise the welfare of the local, unskilled workforce. However, the magnitude of these changes are declining in the initial number of skilled workers in the region. The model is extended to consider imperfectly elastic housing supply. The larger the price elasticity of housing, the larger the range of values, such that more populated regions will host a disproportionate share of skilled workers, have lower levels of intraregional inequality, and provide higher levels of welfare for unskilled workers.     

Dams,Diversions, and Development: Slow Resistance and Authoritarian Rule in the Salween River Basin

We engage geography's longstanding debate on what “counts” as resistance by introducing slow resistance to account for temporal-political strategies against unjust developments, particularly under authoritarian conditions. We draw on over a decade of fieldwork in the Salween River Basin where dams and diversions have been proposed since 1979, including the most recent iteration, the Yuam River water diversion project in Northwest Thailand. We find that resistance by impacted communities and civil society encompasses slow, strategic, and considered actions over time and generations. Such resistance is necessarily protracted to contest developments (re)proposed over decades. By foregrounding the strategic use of time and temporality, we highlight often overlooked actions and strategies of resistance by a diverse range of actors, showing how resistance movements are incremental and interconnected over time, even when “under the radar”. These strategies are key to contesting and (re)shaping the conditions of development in the Basin.     

Regulatory Alchemy: How the Water Cycle Becomes Capital in the California Desert

A proposed project will take water from an aquifer in the California desert to the coast. Lacking final approvals more than 30 years after it started, the project remains a plan despite sizeable opposition. What is its secret? In this paper, I examine the imaginaries of the underground aquifer underneath the lands of Cadiz Inc, the project proponent. While local theories insist the company is at the centre of a Chinatown conspiracy, I argue that the company stays alive through regulatory alchemy, a term that reveals the magic at the heart of scientific and regulatory approval processes. I examine narratives of the aquifer in environmental compliance and financial reporting in order to reveal how regulatory processes become the conditions of profit-making, building on debates in critical legal geography and political ecology.     

The Making of a Regulatory Crisis: Restructuring New York City's Water Supply

Much practically orientated environmental research is marked by a polarity between functionalist abstraction and ahistorical normative discourse. This paper seeks to bridge the divide between theoretical and empirical research through a case study of New York City's water supply. Current processes of socio-economic restructuring are leading to negative environmental consequences obscured by a failure to extend analysis beyond limited temporal, spatial or sectoral scales. Insights from regulationist theory show that a combination of fiscal, political and other developments are bringing about a wide-ranging reformulation of existing patterns of environmental regulation and service provision in the city. The power of the state is being radically diminished in relation to the power of capital and a plethora of different interest groups. A relatively simple centralized model of environmental regulation is being transformed into a complex decentralized pattern involving the emergence of new approaches to urban governance. Further research is needed on the contradictions between capitalist accumulation and environmental regulation at different spatial scales in order to link New York's changing role within the global economy to the declining political legitimacy and fiscal capability of the state to play an extensive role in environmental management.     

Elastic labor supply and agglomeration

This study analyzes the interplay between the agglomeration of economic activities and interregional differences in working hours, which are typically longer in large cities, as they are normally more developed than small cities. For this purpose, we develop a two‐region model with endogenous labor supply. Although we assume a symmetric distribution of immobile workers, the symmetric equilibrium breaks in the sense that firms may agglomerate when trade costs are intermediate and labor supply is elastic. We also show that the price index is always lower, while labor supply, per capita income, real wages, and welfare are always higher in the more agglomerated region.     

Contours of the Past: LiDAR Data Expands the Limits of Late Pre-Columbian Human Settlement in the Santarém Region,Lower Amazon

Recent studies have shown that pre-Columbian societies in the Amazon undertook significant landscape modifications, including earthworks. Our fieldwork has revealed that pre-Columbian settlements in the Santarém Region, Lower Amazon, were not limited to the vicinities of permanent water courses, as formerly often assumed. Instead, numerous archaeological sites, dating from ca. a.d. 1300 up to the time of European colonization in the seventeenth century, have been found in an upland area known as the Belterra Plateau, south of the present-day city of Santarém. These upland sites have been found to be associated with particular features in the landscape: cavities or depressions, known locally as “Poços de Água”. LiDAR data shows that a pattern of non-randomly distributed depressions extends far into the densely forested Tapajós National Forest (Flona-Tapajós), allowing us to suggest that the expansion of inland settlement extended considerably farther to the south than what has previously been established through conventional archaeological fieldwork.     

The Ereğli E Shipwreck,Turkey: an early Hellenistic merchant ship in the Black Sea

A shipwreck from the early 3rd century BC was discovered in the Black Sea's suboxic depths off Ere?li, Turkey, during the 2011 E/V Nautilus expedition. Remote investigation revealed the trawl‐damaged remains of a merchant ship carrying multiple amphora types associated with Aegean and Pontic production areas. Also discovered were elements of the ship's hull that show evidence of both pegged mortise‐and‐tenon and laced construction. The wreck provides crucial archaeological evidence for both maritime connectivity and ship‐construction methods during a period of political and economic transition.
