Crisis? What crisis? Displacing the spatial imaginary of the fiscal state

This paper argues that there is an immanent and evolving relationship between the prevailing form of taxation and the economic geographies of the state. Despite this, the geographic significance of taxation has been obscured by the language in which its historic transformation tends to be couched. Prevailing fiscal systems tend to be presented as essentially static – institutionally and spatially fixed and routinely inscribed within the fixed boundaries and territories of the ‘sovereign’ fiscal state. Any threat to, or change in the nature or geography of the fiscal state tends to be couched in terms of ‘crisis’ – of negative and discontinuous change. This paper contends that these related and essentially conservative discourses of fiscal geography mask the degree to which fiscal spaces are both multiple and continuously evolving. More importantly, it argues, this fluidity and multiplicity does not threaten the stability and viability of state form, but it is an essential process in its maintenance and reproduction. Running counter to the prevailing discourse of the ‘national economy’, the practice of fiscal geography is an under-analysed but key aspect of the historical evolution and transformation of the imagined geographies of economies.

Development and the Household: Missing the point?

Over the past two decades development has been shifting its focus toward smaller scales and particular problems. As a result, the household has become an increasingly important institution for development, and has come under increased scrunity as development practitioners and scholars seek to better understand this institution’s functions and foundations, trying to ‘get the household right’. These efforts, rather than clarifying the character and the function of the household, have contributed to its indeterminacy by reifying the very institution they seek to analyse. Arguing that these efforts fundamentally miss the point of examining the household, this paper introduces a different framework of analysis that addresses the household not as a fixed object of research, but as a local construction that embodies flows of power and knowledge both within and transcending the local. Using the example of varying constructions of the household in two villages in Ghana’s Central Region, this article illustrates how such an approach allows us to address the various functions of the household as particular embodiments of these flows, an approach that better explains the endurance or ephemerality of these functions. Such an approach provides a stronger foundation for the consideration of how particular constructions of this institution may have troubling implications for issues like gender equity and sustainability.

Why did life develop on the surface of the Earth in the Cambrian?

Life was limited for most of Earth's history, remaining at a primitive stage and mostly marine until about 0.55 Ga. In the Paleozoic, life eventually exploded and colonized the continental realm. Why had there been such a long period of delayed evolution of life? Early life was dominated by Archaea and Bacteria,which can survive ionizing radiation better than other organisms. The magnetic field preserves the atmosphere, which is the main shield of UV radiation. We explore the hypothesis that the Cambrian explosion of life could have been enabled by the increase of the magnetic field dipole intensity due to the solidification of the inner core, caused by the cooling of the Earth, and the concomitant decrease with time of the high-energy solar flux since the birth of the solar system. Therefore, the two phenomena could be responsible for the growth and thickening of the atmosphere and the development of land surface life.     

How did the Alxa Block respond to the Indo-Eurasian collision?

The Cenozoic deformation of the Alxa Block resulted directly from the evolution of the northern Qinghai-Tibetan Plateau. However, many data show that the deformation occurred only in the Middle-Late Miocene. Our studies show that the Altyn Tagh fault did not pass through the Alxa Block; on the contrary it went along the southern boundary of the Jintai-Huahai Basin, linking with the Helishan—southern Longshoushan fault. Due to important tectonic events in the northern Qinghai-Tibetan plateau during the Middle-Late Miocene time, the northern plateau underwent rapid uplift and the plateau compressed the Hexi Corridor Region, resulting in a change from NS-trending to EW-trending structures in the Jinta-Huahai basin, and in the development of compressive structures in the Beishan. The southern Alxa fault underwent right lateral movement, and in the northern and central parts of the block, NS-trending Tertiary extensional structures formed. These basins controlled by Tertiary faults are similar to basins developed by lateral extrusion with a strong foreland and weak limited boundaries. The authors suggest that a regional “conjugate” fault system resulted from nearly NS-trending compression from the Qinghai-Tibetan Plateau during the Miocene and Pliocene in the Alxa Block and southern Mongolia. And due to the control of early structures in these regions, most brittle faults reactivated earlier ductile faults; NW–SE faults along the Altai Mountain and NE–SW faults to the southeast in Mongolia consist of a “conjugate” fault system to the north. The Altyn Tagh fault and southern Helishan-Longshoushan fault comprise a “conjugate” fault system to the south. The Beishan and Jinta-Huahai Basin occupied the convergent area between these two sets of faults; the compression controlled the Tertiary deposition and led to the development of the Cenozoic Jinta-Huahai Basin. The Alxa Block bounded by these two sets of faults moved eastwards, which resulted in the development of Cenozoic compressive structures to the west of Helan Shan, and superimposed early ductile shear zones along the northeastern and southwestern boundaries of the Alxa Block respectively. This model could explain the Cenozoic deformation occurring in and around the Alxa region.     

Was the Pliocene-Pleistocene boundary placed at the wrong stratigraphic level?

In 1985 the Pliocene-Pleistocene boundary was designated at the base of the claystone, overlying bed e in the Vrica Section, Italy. This followed a recommendation that the boundary should be at the first physical horizon below the first appearance of Cytheropteron testudo. There is evidence that this supposed ‘cold guest’ has been mis-identified, and it raises the serious question as to whether the boundary could have been better placed.     

Empowering the empowered? Slum tourism and the depoliticization of poverty

Mumbai’s Dharavi slum occupies a plot half the size of Central Park. It is home to one million people, with almost half of residents living in spaces under 10 m², making it over six times as dense as daytime Manhattan. Using ethnographic fieldwork and online analysis, this article examines slum tourism and the perceptions and experiences of western visitors. Local tour operators emphasize the productivity of the slum, with its annual turnover of $665 million generated from its hutment industries. Its poor sanitation, lack of clean water, squalid conditions and overcrowding are ignored and replaced by a vision of resourcefulness, hard work and diligence. This presentation of the slum as a hive of industry is so successful that visitors overlook, or even deny, its obvious poverty. Dharavi is instead perceived as a manufacturing hub and retail experience; and in some cases even romanticized as a model of contentment and neighbourliness, with western visitors transformed by ‘life-changing’, ‘eye-opening’ and ‘mind-blowing’ experiences. This article concludes that the potential of slum tours as a form of international development is limited, as they enable wealthy middle-class westerners to feel ‘inspired’, ‘uplifted’ and ‘enriched’, but with little understanding of the need for change.     

Where have all the commons gone?

Common property resources (CPRs) have provided a basis for sustenance to countless households, especially those that lack access to private assets. Several factors have eroded the access of CPR dependent communities, such as, conscious policy decisions of the state, elite domination, the process of land consolidation and commercialization. In the period of neo-liberal reforms in India, after 1991, the nature of threats to the commons has changed. Emerging factors such as urbanization, land acquisition and real estate development have played a more significant role in depleting the CPRs. The commons have increasingly come to bear the ecological foot-print of urbanization as they got acquired or encroached upon for urban expansion and required infrastructure. This compromises the livelihood security of those who depend on them for sustenance. There is a need for debate on alternative and more sustainable models of urbanization.     

Ecological stability during the LGM and the mid-Holocene in the Alpine Steppes of Tibet?

Arid and Alpine ecosystems are known for extreme environmental changes during the Late Quaternary. We hypothesize that the world's largest Alpine arid ecosystem however, the Alpine Steppes of the Tibetan highlands, remained ecologically stable during the LGM and the mid-Holocene. This hypothesis is tested by distributional range of plant species, plant life forms and rate of endemism. The set of character species has a precipitation gradient between 50 and 350 mm/a, testifying for resilience to precipitation changes. 83% of the species have a wider vertical range than 1000 m used as a proxy for resilience to temperature changes. 30% of the species are endemic with 10 endemic genera, including plate-shaped cushions as a unique plant life form. These findings are in line with palaeo-ecological proxies (δ¹⁸O, pollen) allowing the assumption that Alpine Steppes persisted during the LGM with 3 to 4 K lower summer temperatures.During the mid-Holocene, forests could have replaced Alpine Steppes in the upper catchments of the Huang He, Yangtze, Mekong, Salween and Yarlung Zhangbo, but not in the interior basins of the north-western highlands, because the basins were then flooded, suppressing forests and supporting the environmental stability of this arid Alpine grassland biome.     

Did reefs exist in the Proterozoic?

Analysis of the growth pattern of stromatolites and relationships of their thick carbonate bodies with host rocks are used to substantiate the lack of reefs sensu stricto, i.e., buildups notably towering above the sea bottom, in the Proterozoic.

A constant daylength during the precambrian era?

The semidiurnal atmospheric thermal tide would have been resonant with free oscillations of the atmosphere when the day was ∼ 21 h long, c. 600 Ma ago. Very large atmospheric tides would have resulted, with associated surface pressure oscillations in excess of 10 mbar in the tropics. Near resonance the Sun's gravitational torque on the atmospheric tide - accelerating Earth's rotation - would have been comparable in magnitude to the decelerating lunar torque upon the oceanic tides. The balance of the opposing torques may have long maintained a resonant ∼ 21 h day, perhaps for much of the Precambrian. Because the timescale of lunar orbital evolution is not directly affected, a constant daylength would result in fewer days/month. The hypothesis is shown not to conflict with the available (stromatolitic) evidence. Escape from the resonance could have followed a relatively abrupt global warming, such as that occurring at the end of the Precambrian. Alternatively, escape may simply have followed a major increase in the rate of oceanic tidal dissipation, brought about by the changing topography of the world's oceans. We integrate the history of the lunar orbit with and without a sustained resonance, finding that the impact of a sustained resonance on the other orbital parameters of the Earth-Moon system would not have been large.
