The global ‘land grab’ debate is going urban and needs a specific conceptual framework to analyze the diverse modalities through which land commodification and speculation are transforming cities across the globe. This article identifies new avenues for research on urban land issues by drawing on an extensive body of academic literature and concrete cases of urban land transformations in Asia, Latin America and Africa. These transformations are analyzed by focusing on three types of urban investments – investments in property, investments in public space and public services, and investments in speculation, image building and ‘worlding’ – and the way these investments are intermingled with and enhanced by processes of gentrification and speculative urbanism. Addressing real estate and infrastructure investments, speculation and gentrification through a land-based lens allows us to deepen the discussion on urban land governance in the global South. We argue that urban land acquisition cannot be thoroughly understood in isolation from the workings of urban real estate markets, public policies, and displacement processes. The urban land grab debate needs to consider the dialectic interplay between land use change and general socio-spatial transformations both in central – or recentralized – and peripheral areas. This is why we plea for a kaleidoscopic perspective on urban land governance by uncovering the complex patchwork of urban land acquisitions and their diverse temporalities and spatialities, their hybrid character in terms of actors involved, and the multiple and often unpredicted ways in which urban dwellers try to gain control over and access to urban land.  相似文献

This article uses the case of anti-eviction politics to examine the urban land question. Following the ideas and practices of the Chicago Anti-Eviction Campaign and its global interconnections, it traces the potentialities and limits of poor people’s movements as they battle displacement and enact a politics of emplacement. In doing so, it seeks to expand existing understandings of dispossession. Drawing on critical race studies and postcolonial theory, the article pays attention to the relationship between property and personhood in the context of long histories of racial exclusion and colonial domination. It asks: what politics of home and land is possible outside the grid of secure possession and sovereign self? The work of the Chicago Anti-Eviction Campaign points to how various modes of collectivism can be asserted through practices of occupation as well as through global frameworks of human rights. Challenging the secure categories of property and personhood through which liberalism is constituted, such politics is attuned to the present history of racial banishment but is also subject to aspirations of resolution and possession.  相似文献

This paper examines how the changing and complex notions of home in the context of China’s internal migration can influence migrants’ belonging and identity formations in the urban context. Tracing the evolution of migrants’ conceptualization of home through three interrelated perspectives – the ancestral home (laojia), the city home, and the material home – it is becoming possible to challenge the dominant perceptions of migrants’ home as an emblematic representation of their precarious urban position and its traditional association with formal and fixed alignment between place and identity. Employing a translocal approach to study the complexities and functions of migrants’ home, this paper expose migrants’ alternative home-making practices, highlighting their strong connection to flexibility and mobility, and the making of migrants’ home a meaningful space for subjective transformations, within the limiting environment of powerful socio-spatial urban regimes. Reexamining the reliance on the traditional established connection between place, home, and identity, these new conceptualizations are important not only to better understand the development of migrants’ urban identity and belonging, but can also as be used as a practical element in devising future urban development policies that will better address migrants’ needs and integration into urban space and society.  相似文献

While the concept of urban agriculture investigates the way in which disused land within the consolidated city is returned to its citizens through a variety of farming practices, many pockets of rural land in peri-urban areas continue to be contested by institutions and communities – including informal farmers, formal farmers, municipal planners, metropolitan agencies, and investors – with contrasting interests. To date however, little scholarly attention has been paid to informal practices within the degraded areas of urban fringes and, more specifically, to the link between the expansion of peri-urban agriculture and the civic appropriation and negotiation of space in neglected peripheral areas. In this paper, we ask how a metropolitan sustainability fix is produced and contested both materially and discursively. We also explore how local residents involved in peri-urban agriculture claim the use of land for agricultural practices and in turn attempt to influence the urban agenda of the neoliberal city. Inquiring how competing visions of nature act as obstacles in this negotiation process, our analysis of the peri-urban Baix Llobregat Agricultural Park in Barcelona reveals that the imposition of official visions about how needs for food and agriculture should be fulfilled, which landscapes are esthetically acceptable, what nature is, and how land should be controlled and developed indicate why apparently “marginal” and informal urban agriculture in the periphery has come to be subordinated to the planning of the neoliberal city and of a metropolitan sustainability fix – a partial sustainability fix that is however progressively being questioned and renegotiated.  相似文献

While scholarly concentration has been given to the challenges and opportunities for urban transformation in democratic South Africa, there are still pockets of areas which fall short of intensive examination, particularly in the topic of transforming hidden urban communities. In order to interrogate the socio-economic transformation of the hidden urbanites in a post-apartheid policy regime, this paper draws heavily from empirical evidence of Mdantsane, the second largest township in South Africa. It triangulates data obtained through unstructured in-depth interviews with that gathered from census surveys and other government reports. The study indicates that despite notable policy strides to facilitate the much sought after transformation, Mdantsane’s urban landscape still suffers from development gaps that are largely reflected in socio-economic spatial inequalities. Although these findings generally resonate with scholarly evidence established in other urban areas in South Africa, we argue about the peculiarity of Mdantsane’s case, which is chiefly associated with a complex matrix of policy events and physiographic constraints that would need a revisit if the envisaged development plans are to become a reality.  相似文献

Agricultural land use in much of Brong-Ahafo region, Ghana has been shifting from the production of food crops towards increased cashew nut cultivation in recent years. This article explores everyday, less visible, gendered and generational struggles over family farms in West Africa, based on qualitative, participatory research in a rural community that is becoming increasingly integrated into the global capitalist system. As a tree crop, cashew was regarded as an individual man’s property to be passed on to his wife and children rather than to extended family members, which differed from the communal land tenure arrangements governing food crop cultivation. The tendency for land, cash crops and income to be controlled by men, despite women’s and young people’s significant labour contributions to family farms, and for women to rely on food crop production for their main source of income and for household food security, means that women and girls are more likely to lose out when cashew plantations are expanded to the detriment of land for food crops. Intergenerational tensions emerged when young people felt that their parents and elders were neglecting their views and concerns. The research provides important insights into gendered and generational power relations regarding land access, property rights and intra-household decision-making processes. Greater dialogue between genders and generations may help to tackle unequal power relations and lead to shared decision-making processes that build the resilience of rural communities.  相似文献

This paper introduces a special issue devoted to the sequence of events in and around Glen Roy during the Loch Lomond or Younger Dryas Stadial, the short but important cold period dated to between ∼12,900 and 11,700 years ago, during which glaciers last expanded to occupy the Scottish Highlands, and during the subsequent transition to warmer conditions at the start of the Holocene. The Glen Roy area is internationally famous for the ‘Parallel Roads’, pre-eminent examples of ice-dammed lake shorelines which were formed during the stadial. What makes these shorelines unique, however, is their role as distinctive time markers, allowing the order of formation of landforms and sediments to be construed with unprecedented detail. Varved lake sediments preserved within Glen Roy and nearby Loch Laggan provide a precise timescale – the Lochaber Master Varve Chronology (LMVC) – for establishing the rates and timing of some of the events. This introductory paper first sets the geological context for those new to this topic, with a digest of key advances in understanding made between the nineteenth century and the publication of the LMVC in 2010. It then summarises the evidence and ideas that have emerged from new research investigations reported in this special issue for the first time, and which shine new light on the subject. Two final sections synthesise the new data and consider future prospects for further refinement of the precise sequence and timing of events. A major conclusion to emerge from this new body of work is that the ice-dammed lakes, and the glaciers that impounded them, persisted in the area until around 11,700 to perhaps 11,600 years ago. This conflicts with recently promoted suggestions that the last glaciers in Scotland were already in a state of considerable decline by ∼12,500 years ago.  相似文献

In Southeast Asia’s green economy, conservation interventions intensify the production of resources as commodities through land sparing activities and zoning in extensively used landscapes. Such initiatives encounter problems where poor resource users diversify livelihoods in multi-functional landscapes over time. In terms of ‘livelihood bricolage’ – the mixing, matching and building of portfolios – we describe how forest users enhance security by building dynamic livelihood portfolios based on the economic and socio-cultural considerations of place. Philippine case studies show how disrupting livelihood bricolage in multi-functional landscapes with ‘intensifying interventions’ spatially constrains livelihood security and conservation objectives. We conclude that more equitable forest governance supports land sharing with diverse, extensive livelihoods in varied landscapes.  相似文献

An effective and efficient planning of an urban growth and land use changes and its impact on the environment requires information about growth trends and patterns amongst other important information. Over the years, many urban growth models have been developed and used in the developed countries for forecasting growth patterns. In the developing countries however, there exist a very few studies showing the application of these models and their performances. In this study two models such as cellular automata (CA) and the SLEUTH models are applied in a geographical information system (GIS) to simulate and predict the urban growth and land use change for the City of Sana’a (Yemen) for the period 2004–2020. GIS based maps were generated for the urban growth pattern of the city which was further analyzed using geo-statistical techniques. During the models calibration process, a total of 35 years of time series dataset such as historical topographical maps, aerial photographs and satellite imageries was used to identify the parameters that influenced the urban growth. The validation result showed an overall accuracy of 99.6 %; with the producer’s accuracy of 83.3 % and the user’s accuracy 83.6 %. The SLEUTH model used the best fit growth rule parameters during the calibration to forecasting future urban growth pattern and generated various probability maps in which the individual grid cells are urbanized assuming unique “urban growth signatures”. The models generated future urban growth pattern and land use changes from the period 2004–2020. Both models proved effective in forecasting growth pattern that will be useful in planning and decision making. In comparison, the CA model growth pattern showed high density development, in which growth edges were filled and clusters were merged together to form a compact built-up area wherein less agricultural lands were included. On the contrary, the SLEUTH model growth pattern showed more urban sprawl and low-density development that included substantial areas of agricultural lands.  相似文献

Carbon forestry has become a cornerstone of attempted climate change mitigation in developing countries. As such, dozens of projects have been developed to supply carbon offsets to both voluntary and regulated carbon markets. In this paper we shed further light on the effects of such projects on communities and households by studying the implementation of a carbon forestry project in four communities in the state of Chiapas, Mexico. The project pays farmers to carry out a number of tree-planting activities depending on the local agro-ecological systems. We investigate how such activities have been promoted in and adopted by communities and we identify a series of community-based, institutional, resource management and asset-related factors that explain farmers’ willingness to participate in the projects. Our analysis highlights a number of shared motivations for joining the project but varied levels of understanding about the project rationale. We also show how community norms, access to land tenure, financial and physical assets differ among participants and non-participants which translates in increasing inequalities in access to income and to other development projects. However, we also demonstrate that project activities, as currently designed, motivate some farmers to participate because of the potential of the project to act as a mechanism to bridge existing social divides through cooperation in the project and therefore financially and politically benefit from participation. Overall, the paper demonstrates that the project contributes to transforming local livelihoods and institutions, unfortunately not always as originally designed.  相似文献

Urban soil nitrogen and phosphorus have significant implications for the soil and water quality in urban areas. The concentrations of total nitrogen (TN) and total phosphorus (TP) of soil samples collected from six types of land use, which included residential area (RA), business area (BA), classical garden (CG), culture and education area (CEA), public green space (PGS) and roadside area (RSA) of Beijing urban area, were investigated. Results showed that the geometric mean of TP (857 mg/kg) in urban soils was slightly higher than that (745 mg/kg) in rural soils of Beijing. The concentration of soil TP was higher in the center of the city, and showed an increasing trend with the age of the urban area. The TP concentrations in the six types of land use followed the sequence of CG > BA > RSA > RA > CEA > PGS, which were affected by the use and disposal of phosphorus-containing materials in each type of land use. However, the geometric mean of TN (753.8 mg/kg) in urban soils was much lower than that (1,933.3 mg/kg) in rural soils. TN level in urban soils of Beijing had no correlation with the city’s urbanization history, and was influenced by the coverage of natural vegetation and human activities in each type of land use. This study suggested that the city’s urbanization history and land use were the main factors affecting the distribution of nitrogen and phosphorus in urban soils.  相似文献

This article examines the post-emancipation contests over agricultural land in the South Carolina Lowcountry – the coastal region surrounding the port city of Charleston – in the context of recent theorizations of plantation geographies and the racial politics of the US Department of Agriculture (USDA). In the aftermath of slavery, freedpeople in the Lowcountry were remarkably successful in securing control over their labor and access to land. The measure of relative autonomy that came with these gains spurred enormous anxiety for white elites, however, who realized that black control over land and labor threatened to upend the region’s racial hierarchy. I argue that plantation geographies persist through the white monopolization of land, and suggest that successfully challenging this historical trajectory depends on challenging liberal modes of improvement.  相似文献

Glen Roy is a classic geosite for ice-dammed lake shorelines, the Parallel Roads, and associated features formed during the Loch Lomond (Younger Dryas) Stade (12.9–11.7 ka). The area played a key part in the development of the glacial theory in the early 19th century and continues today to have outstanding scientific value for understanding the processes and timing of events at the end of the last glaciation. Glen Roy has also been long-appreciated as an awe-inspiring visitor attraction, and is now a flagship site for geotourism within Lochaber Geopark. Statutory geoconservation in Glen Roy, beginning in the second half of the 20th century, was founded on the exceptional scientific value of the area. The history and practice of geoconservation in Glen Roy illustrate the contested values of geoheritage and the evolving approaches adopted. Important lessons include the need for open dialogue and partnership working among the local community, land owners and managers, the statutory conservation agency (Scottish Natural Heritage), Lochaber Geopark and the scientific community.  相似文献

New lithostratigraphical, pollen-stratigraphical and tephrostratigraphical data are presented for a sediment sequence at Turret Bank, a site that lies close to the confluence of the River Turret with the River Roy in Lochaber, the western Scottish Highlands. The site is also adjacent to the inner margin of a major gravel fan, the Glen Turret Fan, the age of which has been debated and has a crucial bearing on the overall sequence of events in Glen Roy, especially concerning the maximum limit of Loch Lomond Readvance (Younger Dryas) ice. Several lines of evidence point to the sediment sequence at Turret Bank having been wholly deposited during the Loch Lomond Stadial-early Holocene transition: (i) the pollen sequence is typical for this transitional period; (ii) varved deposits preserved in the sequence bear a strong resemblance to mid-Stadial varves in a regional master varve scheme for Glen Roy and vicinity (the Lochaber Master Varve Chronology); and (iii) an early Holocene tephra – the Askja-S Tephra – is preserved within the sequence. Some limitations with the new data are considered, but it is concluded that the coherent integration of lithostratigraphic, geomorphological, pollen-stratigraphical and tephrostratigraphical data point to the likelihood that Loch Lomond Readvance ice extended to the inner margin of the Glen Turret Fan, and that the fan was probably constructed by glacial meltwaters at this time.  相似文献

This paper critically examines the concepts of “dis/possessive collectivism,” “the politics of emplacement,” and “city's end” developed in Ananya Roy’s 2016 Geoforum Lecture. It does so by reflecting on global anti-eviction struggles, as well as theories of performative politics and racial capitalism, in order to develop—in line with the ethic of learning Roy articulates in her paper—how poor people's movements develop living critiques of property and liberal standards of propriety.  相似文献

In spite of continued mass urban protests in post-apartheid South Africa, few are the social movements or individuals which openly disengage from the dominant and former liberation party, the African National Congress. Many authors have analysed this paradox as a two-pronged strategy, ‘the brick’ and ‘the ballot’, to try and influence public policy. However, these two political positions become increasingly contradictory and difficult to hold together, as the ANC becomes more and more intolerant towards social movements. This paper, using the example of women’s contention about water commodification in Phiri (Soweto), examines how activists shape their opposition whilst still stating their affiliation to the ruling party. They manage these contradicting political loyalties through a variety of tactics exonerating the ANC from the blame of urban mismanagement: contrasting the current ANC with the ‘real’ ANC of the past – to which they remain faithful; and blaming the ‘deployees’ of the ANC at the local level for betraying the ‘real’ ANC at the national level. These tactics however may be short-lived as social movements upscale their action to the national level.  相似文献

This article sets out an agenda for research that (re)connects research on children’s geographies and childhood studies with studies of spatial literacy. Research on children’s environmental cognition and, latterly, spatial literacy, has been artificially and problematically separated from the majority of research in childhood studies. Our fundamental aim in this article is to argue for – and to evidence – greater attention to how spatial literacy and children’s everyday lives are embedded in one another. To support our broader call for a synthetic research agenda, we draw on some more focussed, qualitative empirical material taken from a large-scale project about children’s mobilities and everyday lives in newly-built urban communities. Our analysis focuses upon children’s interpretations of Global Positioning Systems (GPS) tracks of their mobilities, set against a background of Google Earth imagery. In doing so, we showcase one suite of ways in which research on environmental cognition and children’s geographies might proceed together. We demonstrate that children not only displayed analytical skills (for instance, in relation to scaling effects and pattern recognition) but that many also exercised higher-level, critical analysis, especially in relation to errors on Google Earth outputs. Simultaneously, we interrogate the recursive articulation of a range of qualitative indicators of spatial literacy, with children’s everyday mobilities, routines, emotions and memories. The paper analyses how new conceptual languages and technologies being propounded by spatial literacy scholars could afford a more enriched understanding of key contemporary concerns for children’s geographers, and, recursively, what spatial literacy scholars might gain from engaging with (especially qualitative) research prompted by those concerns.  相似文献

Through the lens of the dancing body, this paper examines practices of health and wellbeing produced in response to City of Vancouver urban governance policies. In particular, it calls attention to the legislative onslaught by city government in the years abutting the 2010 Winter Olympics to cultivate and manage healthy people, communities, and environments. In an effort to sell Vancouver’s ‘liveability’, I argue City of Vancouver endorsed a new legislative alliance that merged a conspicuously Anglo-American wellbeing lexicon, favouring individual responsibility and self-governance, with the performing arts industries. Drawing upon interviews and performance-based research, the paper illustrates how Karen Jamieson’s community dance project Connect, created for the In the Heart of the City festival, embodies Vancouver’s tri-level legislative ambitions to nurture A Healthy City For All. This materialised through the crafting of a dance-health body practice (healthy people), by choreographing a sense of belonging among ‘at risk’ communities (healthy communities), and in the uniting of the arts and health professions in the process of ‘cleaning up’ disenfranchised neighbourhoods (healthy environments). In bringing together scholarship on cultures of wellbeing and creative dance practice, the article contributes to understandings of how the health-seeking subject is embodied and performed. It also offers a productive critique of the exclusionary nature of urban health legislation, and of the contested role artists and arts festivals can play in nurturing urban wellbeing and normalising inequalities.  相似文献

Land in most of Africa is controlled under the customary tenure system which is governed by well intentioned social and cultural rules meant to grant equal access to families within groups with common interest in land. Rapid changes in the domestic situation of countries resulting from both refractions of policies and influences from the global economy and emerging complexities within the local socio-economic context has altered the traditional land tenure systems in most parts of Africa. In the rural setting and for agricultural purposes, the customary tenure system seems to be crumbling slowly, while in the urban centres and for housing, industrial and commercial purposes the system has collapsed in favour of a commoditised one. The emerging patterns of access in Northern Ghana show growing inequalities in access, control and ownership. There is the need for a new architecture of land rights negotiated by a participatory process and regulated by both state and traditional institutions.  相似文献
