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

Land use change scenarios and associated groundwater impacts in a protected peri-urban area 总被引：1，自引：1，他引：0
Land use changes in peri-urban areas are usually associated with significant impacts on groundwater resources due to alteration
of the recharge regime as well as through the establishment of pollution sources. Quantifying the aforementioned impacts and
assessing the vulnerability of the groundwater resources is an important step for the better management and protection of
the aquifers. In the present study, a physically based, distributed hydrologic model has been used to identify the impacts
from specific land use change scenarios in the protected area of Loutraki catchment. A vulnerability assessment method has
been also implemented to provide a decision support tool to the land planning authorities and also hydrologic mitigation measures
for the sustainable development of the area have been proposed. The hydrologic impacts of the land use scenarios include a
5% reduction in the annual recharge of the study aquifer for scenario 1 (doubling of the current urban areas) and 7% decrease
for scenario 2 (tripling of the current urban areas). Nevertheless, these impacts can be minimised if small-scale artificial
recharge infrastructure is developed and the land planning measures suggested through the vulnerability and recharge maps
will be followed. 相似文献

Changing social and economic drivers of land use require a more integrated approach to land conservation that addresses both the land and the socio-economic context of land use. Technical and legal conservation focused at the single-parcel scale is insufficient. This research examines ecological entrepreneurship, discussed by Marsden and Smith (2005), as an integrated conservation strategy that targets environmental as well as economic goals. Specifically, we explore the roles and functions that must be provided by Ecological Entrepreneurship Support Networks (EESNs). In particular, we look at land trusts engaging in these efforts. Through a series of case studies, we examine the roles and functions, as well as motivations and challenges faced by land trusts involved in EESNs. The lessons learned through these case studies are intended to inform broader sustainable development efforts. 相似文献

Land is a primary resource for international tourism development. The relation of indigenous systems of land tenure and the history of land alienation to tourism in Pacific Island nations, however, is problematic. Governments of some Pacific Island nations are now emphasizing the traditional land rights of indigenous people in determining land use for economic development. Land is a key resource for the local participation of Islanders in development, and indigenous land claims are a volatile political issue. There has been little substantive research on tourism and land tenure in Melanesia. This paper examines the history of the problem of land alienation, the nature of traditional land tenure, and the relation of current land claims to tourist development in Vanuatu. Land alienations are tied to modern tourist developments, and issues of land tenure are a central aspects of political debate in local cultures. Suggestions are offered for regional planning for tourism, and local control of tourist development and land use. 相似文献

Nowadays, the difficulties of the mining sector in accessing the territory are mostly related to inadequate land use plans. Mineral potential maps have become quite relevant for the land use planning authorities as a decision support tool. This work’s goal is to present a methodology based on geological criteria, for the delimitation of potential areas for ornamental stones production in a limestone area of Portugal known as Maciço Calcário Estremenho. This is one of the world’s most important regions producing limestone blocks for ornamental purposes. The methodology, applied at a scale similar to the commonly used in land use planning, considers two main geological-based criteria for the definition of potential areas, namely the homogeneity criterion, related to the textural and chromatic homogeneity of the potentially productive lithologic units, and the dimension criterion, which refers to the thickness of the productive unit, to the volume of the deposit and to its spatial layout. Based on the criteria, two main types of potential areas for ornamental stones’ production were delimited: specific areas, where the lithostratigraphic units demonstrate ornamental suitability at a very local scale due to highly appreciated particular features, and areas corresponding to the entire outcrop area of some of the lithostratigraphic units, which due to the resource volume are the most relevant potential areas. 相似文献

While national figures of land availability are used to justify accepting large-scale land investors, not very much is known about the local level realities of land availability. By combining remotely sensed data with fieldwork, system dynamics modelling and qualitative research methods, we examine local level realities of land use and availability in the Malen Chiefdom of Southern Sierra Leone. Here, local communities are experiencing the outcomes of large-scale investments in oil palm for biodiesel and other industrial purposes by the SOCFIN Agricultural Company. We find that beyond agricultural production, there are other land uses that are vital for the socio-cultural, economic and environmental realities of communities. The Company does not respect engagements promised to local people to set aside buffer zones around living areas to serve as biodiversity corridors. Local communities are severely deprived of agricultural land and other land resources. The operations of SOCFIN do not take account of present or future land needs of local people. A baseline requirement of food crop land should be set aside for each community, to ensure the attainment of food security in communities affected by land acquisitions. Such baseline requirement should be augmented with local level needs assessments to meet new demand for cropland necessitated by changing demography. This model of land planning can be applied to other land use and additional engagements of large-scale land investors. 相似文献

The semi-arid areas in Northern China are home to a large population and have great ecological vulnerability. Contemporary land use pressures cause these areas to suffer from a severe land use conflict between human activities and environmental conservation. Ignoring the livelihood of humans and the development of semi-arid areas is not possible. However, the rapid increase in human activity recently exposes both the human race and local environment to potential adverse effects. To balance this contradiction, this research puts forth a framework to optimize the land use patterns in these areas in the context of ecological security and land use suitability. Considering the expansion of particular land use forms to meet the land use demand of social development, a revised cellular automata model is employed to shape the path of land expansion. Meanwhile, additional adjustment rules are set to adjust the unreasonable land use units to a suitable form. The city of Ordos is chosen as a case to put this framework into practice, and several landscape pattern indexes are used to evaluate the results. The results reveal that this framework could maintain the environment in a stable state while simultaneously meeting the land use demand of social development. 相似文献

目前我国历史文化遗迹所在地区开发用地失控的原因,从体制方面讲,乃是由于规制手段不够健全、管理体制不够顺畅、城镇化和旅游经济发展进程的阶段性等问题所致;从微观经济层面而言,还在于农民缺乏保护农地的经济诱因、农地转向开发用地收益更高、相关利益集团的势力影响等因素在起作用,故而农地流转成开发用地不可避免。所以应当借鉴海外土地发展权制度,在历史文化遗迹所在地区内落实土地发展权的补偿机制,对开发用地实行有效的管制。具体来说,应当从法律上明确土地发展权的地位,将农地保护与当地的经济社会发展有机协调起来,推行土地使用管制,建立完善土地发展权交易机制,同时有效控制农地流转为开发用地的隐性交易行为。 相似文献

They study examines the relationship between the social and economic environments of the tribal people of Baluchistan. It
also evaluates how tribal organizations have been affected by geographic and economic constraints. Analyzing the spatial relationship
between economic development and social structure, study has been made to isolate the effect of interrelated technical, economic
and ecological processes accompanying development in Baluchistan. In the light of the current planning policies adopted in
the area, an attempt has been made to determine whether any measurable spatial restructuring of these simple communities has
occurred at macro and micro levels. 相似文献

Agriculture has ceased to be the major employer in the rural areas of East Germany. Far-reaching structural change has resulted
in a sharp decrease in employment and the mono-structural character of villages has been lost. Unemployment is now a major
problem and women are worst affected. New jobs have been created in construction and elsewhere in the tertiary sector but
most people who have found new jobs have to commute to the towns or migrate permanently to the urban areas. A north-south
contrast has developed because the more developed network of towns in the latter, combined with a relatively good infrastructure,
has enabled many villages to survive as viable communities. An example is Fuchshain near Leipzig where employment with the
farming company (the former cooperative with 4200 ha of land) has declined but the population has grown through new housing
built for commuters. In the north there has been much depopulation and many houses are used as second homes. Either way there
is more conflict occurring now within rural communities because of tensions between the employed and the unemployed and between
old and new residents. It is therefore important that land use planning should take into account the changed economic and
social profiles and measures should be adopted to ensure that the countryside remains visually attractive and socially cohesive.
