Occupational genders and gendered occupations: the case of water provisioning in Maputo,Mozambique

Taking issue with how associations between technical prowess or entrepreneurship and masculinity tend to be taken for granted or are seen as stemming from natural or intrinsic gender differences, over the last two decades feminist scholars have developed theoretical approaches to understand the gendering of professions and abilities as the performative outcome of particular cultures and histories. We build on these insights to explore how associations between masculinities, technology and entrepreneurship shape ideas and practices of small-scale water provision in Maputo. Our findings show how activities (i.e. technical craftsmanship, hard physical work) or abilities (i.e. risk-taking, innovativeness) regarded as masculine tend to be considered the defining features of the profession. This shapes how men and women make sense of and talk about their work, each of them tactically emphasizing and performing those aspects best fitting their gender. Our detailed documentation of men’s and women’s everyday involvements in water provisioning challenges the existence of sharp boundaries and distinctions between genders and professional responsibilities. It shows that water provisioning requires many other types of work and skills and male and female household members collaborate and share their work. The strong normative-cultural associations between gender and water provisioning lead to a distinct under-recognition of women’s importance as water providers. We conclude that strategies to effectively support small-scale water businesses while creating more space and power for women involved in the business require the explicit recognition and re-conceptualization of water provisioning as a household business.     

Studies in Urban Ecology: Strangler Figs in the Urban Parklands of Brisbane,Queensland, Australia

This study investigated the establishment dynamics of strangler figs and the constraints on their development in the urban parklands of Brisbane, Queensland, Australia. Of 3580 trees and palms in the study parks, approximately 5% support at least one Ficus species. Six Ficus species occur epiphytically in older parkland. Four are Brisbane natives: F. macrophylla, F. obliqua, F. platypoda and F. virens; and two are from elsewhere in Australia: F. benjamina and F. rubiginosa. A lack of pollinator wasps in the Brisbane area prevents exotic and other native Ficus spp. from reproducing. Though they form predominantly open communities, the percentage of phorophytes (support trees) in the study parks is similar to that associated with natural, closed communities. Ficus spp. become established in structural features that accumulate humic soil, such as the forks of trunks and branches on trees, and behind marcescent leaf bases on palms. Plants with few humus pockets support few Ficus species. Environmental factors such as atmospheric quality, canopy shade, bark texture and whether or not a park is irrigated, seem not to be consequential to Ficus establishment. Significantly greater numbers of Ficus occur on deciduous trees, perhaps because avian seed dispersers favour them as perches over evergreen trees. Ficus also occur significantly more frequently on the western sides of palms with marcescent leaf bases. These western flanks offer shelter from the prevailing sea breezes: fewer Ficus are therefore likely to be torn from these sides in strong winds.     

Urban Form,Sustainability and Health: The Case of Greater Oslo

Several studies have shown dense urban structures to be favourable in order to reduce greenhouse gas emissions from transport, limit energy consumption in buildings and protect farmland and natural areas in the surroundings of the city. There may, however, be some tensions between such a compact urban developmental strategy and considerations of public health in urban planning. This paper reviews findings from international research on the relationships between urban form and health and illustrates some of these effects by comparing statistics on life expectancy and the frequency of heart attacks among inhabitants of different urban districts in the Norwegian capital Oslo. Since we have only had access to aggregate figures at the level of urban districts, the results must be interpreted with caution. The currently available results do, however, suggest that the densification strategies often recommended for reducing the ecological footprints of cities might be encumbered with some important drawbacks, seen from a public health perspective. Based on the findings, some dilemmas and perspectives for sustainability- and health-oriented urban planning are discussed.     

Urban Political Ecology, Justice and the Politics of Scale

This and the subsequent papers in this special issue set out the contours of Marxian urban political ecology and call for greater research attention to a neglected field of critical research that, given its political importance, requires urgent attention. Notwithstanding the important contributions of other critical perspectives on urban ecology, Marxist urban political ecology provides an integrated and relational approach that helps untangle the interconnected economic, political, social and ecological processes that together go to form highly uneven and deeply unjust urban landscapes. Because the power-laden socioecological relations that shape the formation of urban environments constantly shift between groups of actors and scales, historical-geographical insights into these ever-changing urban configurations are necessary for the sake of considering the future of radical political-ecological urban strategies. The social production of urban environments is gaining recognition within radical and historical-materialist geography. The political programme, then, of urban political ecology is to enhance the democratic content of socioenvironmental construction by identifying the strategies through which a more equitable distribution of social power and a more inclusive mode of environmental production can be achieved.     

美国城市史学中的人文生态学理论

城市史学作为历史学的一个分支学科是在20世纪60年代出现的,它是以埃里克．E．兰帕德的《美国历史学家和城市化研究》一的发表作为新城市史学与旧的方志式的城市史相区别的标志。他在章中明确提出了城市化研究应该作为城市史学家主要致力．的任务,应该把城市社会诸多关联的方面作为一个生态复合体来研究。以后,关于城市化的理论在这一学科范围内不断深化和发展,直至今天,人们约定俗成,承认60年代是城市史学诞生的年代。     

Negotiating Green Space with Landed Interests: The Urban Political Ecology of Greenway in the Pearl River Delta,China

Land‐centred urbanisation has precipitated shortage of green space in Chinese cities. However, in the Pearl River Delta, an ambitious greenway system has recently managed to flourish. It is intriguing to ask how this has become possible. Informed by the perspective of urban political ecology, this paper finds that the greenway project in the Pearl River Delta represents a set of politically realistic endeavours to alleviate urban green space shortage by adapting to, rather than challenging, powerful landed interests. Three interlocking dimensions about land—municipal land quota, rural land use claims, and real estate development—have influenced why, where and how greenways have been created. Based on these findings, we argue that research on China's politics of urban sustainability necessarily needs to understand the country's land politics.     

Green Infrastructure,Grey Epistemologies,and the Urban Political Ecology of Pittsburgh's Water Governance

This paper explores Pittsburgh's water governance to consider the way divergent approaches to urban stormwater management reproduce existing urban metabolisms and belie more radical possibilities for the urban hydro‐social cycle. Federal action has forced municipalities in the Pittsburgh metropolitan region to make changes to its urban water systems and develop a plan to comply with water quality regulations. Within Pittsburgh's water governance debates, compliance centers on various sets of technological strategies for defining and solving purportedly wicked urban environmental problems. Urban political ecology, here, is used to deconstruct the tensions and convergences between these different stormwater governance strategies. I argue that green infrastructure approaches (whose intentions are to expand practice and participation) are framed by dominant grey epistemological approaches. In this view, alternative and creative forms of greening the city may not necessarily represent a more democratic process, but instead reproduce uneven urban landscapes under greener cover.     

Provincializing Urban Political Ecology: Towards a Situated UPE Through African Urbanism

Urban political ecology (UPE) has provided critical insights into the sociomaterial construction of urban environments, their unequal distribution of resources, and contestation over power and resources. Most of this work is rooted in Marxist urban geographical theory, which provides a useful but limited analysis. Such works typically begin with a historical‐materialist theory of power, then examine particular artifacts and infrastructure to provide a critique of society. We argue that there are multiple ways of expanding this framing, including through political ecology or wider currents of Marxism. Here, we demonstrate one possibility: starting from theory and empirics in the South, specifically, African urbanism. We show how African urbanism can inform UPE and the associated research methods, theory and practice to create a more situated UPE. We begin suggesting what a situated UPE might entail: starting with everyday practices, examining diffuse forms of power, and opening the scope for radical incrementalism. © 2013 The Author.

Applying the Strategic‐Relational Approach to Urban Political Ecology: The Water Management Problems of the Baixada Fluminense,Rio de Janeiro,Brazil

Abstract: The complexity of water management requires an explanatory framework that is able to capture the multidimensionality of the relations between nature and society increasingly mediated by the state. The evolution of water problems in the Baixada Fluminense, a wetland area situated to the north of Rio de Janeiro, provides a paradigmatic example of how water management becomes incorporated into the fluid politics between state, nature and society. The local experience is examined by making use of the strategic‐relational approach (after Bob Jessop) expanded to urban political ecology. The concept of “trialectics” is proposed as an ontological representation of the interconnections between the state apparatus, class‐based relations and the socionatural elements of the water cycle. The empirical results show that, in a situation of precarious water supply, regular flooding and severe river degradation, state interventions have tended to favour certain groups and areas, which only intensifies the politicisation of water management.     

Towards Situated Analyses of Uneven Peri-Urbanisation: An (Urban) Political Ecology Perspective

In this article we develop a novel analytical framework for situated studies of uneven peri-urbanisation that resist further dividing Marxist and Situated (Urban) Political Ecology. We conceptualise uneven peri-urbanisation as a process in which access to the resources mobilised for peri-urban developments, such as water or land, is rendered uneven. In a three-step approach we suggest, first, describing how peri-urbanisation unfolds in the case being studied and distinguish it from other processes, such as suburbanisation. Second, we propose analysing the transformations of nature on which the peri-urbanisation process is based; and third, examining the uneven power relations infusing inequalities into these transformations and consequently into the peri-urbanisation process described. To allow for a situated analysis this approach regards the study of practices as crucial, but they have to be embedded in wider socio-economic, political, and historical processes, since both contribute to transformations of nature and thus shape uneven peri-urbanisation.     

Late Holocene Historical Ecology: The Timing of Vertebrate Extirpation on Crooked Island,Commonwealth of The Bahamas

We report eight new accelerator-mass spectrometer (AMS) radiocarbon (¹⁴C) dates performed directly on individual bones of extirpated species from Crooked Island, The Bahamas. Three dates from the hutia (Geocapromys ingrahami), recovered from a culturally derived bone assemblage in McKay's Bluff Cave (site CR-5), all broadly overlap from AD 1450 to 1620, which encompasses the time of first European contact with the Lucayan on Crooked Island (AD 1492). Marine fish and hutia dominate the bone assemblage at McKay's Bluff Cave, shedding light on vertebrate consumption by the Lucayans just before their demise. A fourth AMS ¹⁴C date on a hutia bone, from a non-cultural surface context in Crossbed Cave (site CR-25), is similar (AD 1465 to 1645) to those from McKay's Bluff Cave. From Pittstown Landing (site CR-14), an open coastal archaeological site, a femur of the Cuban crocodile (Crocodylus rhombifer) yielded an AMS ¹⁴C date of AD ～1050–1250, which is early in the Lucayan cultural sequence. From a humerus in a non-cultural surface context in 1702 Cave (site CR-26), we document survival of the Cuban crocodile on Crooked Island until AD ～1300–1400, which is several hundred years later than the well-documented extinction of Cuban crocodiles on Abaco in the northern Bahamas. We lack a clear explanation of why Cuban crocodiles likely survived longer on Crooked Island than on a larger Bahamian island such as Abaco. One AMS ¹⁴C date on Crooked Island's extinct, undescribed species of tortoise (Chelonoidis sp.) from 1702 Cave is BC 790 to 540 (2740 to 2490 cal BP), which is ～1500–1700 years prior to human arrival. A second AMS ¹⁴C date, on a fibula of this tortoise from McKay's Bluff Cave, is AD 1025 to 1165, thereby demonstrating survival of this extinct species into the period of human occupation.     

Studies in Urban Ecology: the First Wave of Biological Invasion by Pistacia chinensis in Armidale,New South Wales,Australia

Biological invasions by deliberately introduced organisms seriously compromise the integrity of ecosystems, but their early stages have seldom been documented, especially in urban contexts. Since the 1940s, the small Asian tree Pistacia chinensis has been widely planted in streets and gardens in Armidale, New South Wales, Australia, where it makes a major contribution to the autumn colours that are exploited to promote the city. Numerous wild plants are now becoming established in and near Armidale. This ongoing biological invasion may have been accelerated by the large size of the initial (planted) population, and by the presence of efficient avian seed dispersers. It is now at the stage of the first wild generation reaching reproductive maturity. While it is probably still possible to halt the invasion, various human factors appear to make this an unlikely prospect.     

敦煌《诗经》卷子研读札记二则

本共有两则札记。第一则是《S．10号(毛诗传笺)卷背注音之性质》。S．10号《毛诗传笺》卷背有145字之注音,潘重规认为这是六朝《音隐》类作之遗迹,《英藏敦煌献》据之定名为《毛诗郑笺音隐》。本从卷背注音与正面字的关系上考察,认为卷背注音是抄写人据某种《毛诗音》移录,并非是与正字合成有机整体的《毛诗郑笺音隐》,只是它用以注音的方法与六朝的音隐类作相同而已。第二则是《S．541号写卷的正面与背面》,S．541号写卷的一面抄写有《诗经》,另一面抄写有佛典《因缘心释论开决记》。本否定了以前诸家目录以抄写《诗经》一面为背面的说法,认为抄写有《诗经》的一面应是写卷的正面,而抄有佛典一面的内容则为其背面。
