Delineation of groundwater recharge zones and identification of artificial recharge sites in West Medinipur district,West Bengal,using RS,GIS and MCDM techniques 总被引:14,自引:4,他引:10
Artificial recharge plays a pivotal role in the sustainable management of groundwater resources. This study proposes a methodology
to delineate artificial recharge zones as well as to identify favorable artificial recharge sites using integrated remote
sensing (RS), geographical information system (GIS) and multi-criteria decision making (MCDM) techniques for augmenting groundwater
resources in the West Medinipur district of West Bengal, India, which has been facing water shortage problems for the past
few years. The thematic layers considered in this study are: geomorphology, geology, drainage density, slope and aquifer transmissivity,
which were prepared using IRS-1D imagery and conventional data. Different themes and their corresponding features were assigned
proper weights based on their relative contribution to groundwater recharge in the area, and normalized weights were computed
using the Saaty’s analytic hierarchy process (AHP). These thematic layers were then integrated in the GIS environment to delineate
artificial recharge zones in the study area. The artificial recharge map thus obtained divided the study area into three zones,
viz., ‘suitable,’ ‘moderately suitable’ and ‘unsuitable’ according to their suitability for artificial groundwater recharge.
It was found that about 46% of the study area falls under ‘suitable’ zone, whereas 43% falls under the ‘moderately suitable’
zone. The western portion of the study area was found to be unsuitable for artificial recharge. The artificial recharge zone
map of the study area was found to be in agreement with the map of mean groundwater depths over the area. Furthermore, forty
possible sites for artificial recharge were also identified using RS and GIS techniques. Based on the available field information,
check dams are suggested as promising artificial recharge structures. The results of this study could be used to formulate
an efficient groundwater management plan for the study area so as to ensure sustainable utilization of scarce groundwater
resources. 相似文献

Groundwater has played an important role in economic development in Southeast Asian countries, but some problems caused by
nature or human actions such as contamination, over pumping, and land subsidence bring the necessity of more systematic groundwater
monitoring wells. The analytical hierarchy process with pairwise comparison was used to allocate and organize the regional
groundwater monitoring wells in five regions, Thailand, Cambodia, East/West Malaysia, and South Korea. Five different multi
criteria decision models, which were composed of three primary criteria and eight secondary criteria, were developed based
on the answers of the questionnaire from 76 groundwater experts in Thailand, 100 in Cambodia, 101 in East Malaysia, 87 in
West Malaysia, and 93 in South Korea. It was revealed that the weights of model criteria for each country, which also represent
relative importance on groundwater monitoring, were different according to the diverse groundwater situation. The most important
factor to determine the number of monitoring well was ‘number of households using only groundwater as a water source’ for
Thailand and South Korea, ‘number of contamination sources’ for Cambodia, ‘amount of groundwater use for drinking-water supply’
for East Malaysia, and ‘number of wells with contaminated water’ for West Malaysia. 相似文献

Assuming the above quote as a true portrayal of pilgrims, this article attempts to describe the prototypical pilgrim from
amongst the wide array of contemporary religious and secular tourists. To achieve this end, two approaches have been adopted.
Firstly, the phenomenon/concept of pilgrimages have been discussed, so to distinguish it from the tourism phenomenon and;
Secondly, the geographical notion of genus loci has been employed to exemplify the fundamental quest for ‘geopiety’ attained
through the unification of the pilgrim’s intrinsic belief with its external location. The second part of the article illustrates
the forgoing through an exploration of Himalayan pilgrimages. This has been achieved with a discussion of the emerging practices
and recent trends in Himalayan pilgrimology. This appraisal alludes to Cohen’s quest for a ‘Theology of Tourism.’ The article
concludes with an examination of a specific genre of contemporary tourists in the Indian Himalayas, who have been identified
as ‘environmental pilgrims.’

There is growing recognition among political ecologists of the need to examine shifting natural resource regimes and their
effects on livelihoods in “First World” places. This emerging literature has variously examined the “Third World within,”
the persistence of “subsistence activities” in the “First World,” and the “reterritorialization” of land tenure and access.
However, much of this work has tended to focus on traditional extractive industries in the American West, indigenous claims
to lands and resources in the U.S. and Canada, and non-timber resources on public lands. In contrast, we use a case study
of African-American sweetgrass basket-makers, associated with the Gullah culture, in South Carolina’s lowcountry to examine
the ways in which ongoing amenity-driven residential development is fundamentally reshaping resource access on private lands.
Historically, basket-makers harvested the materials (primarily sweetgrass or Mulenbergia filipes) needed for their culturally
important art form from accessible, rural, and privately held tracts of land in close proximity to their communities, but
development pressures and changes in resident interpretation of property rights has decreased access to basket-making resources.
The case is particularly illuminating, as it examines the emergence of ‘conservation subdivisions’ in the region and raises
important questions about what “rural uses” and users are being conserved through responses to exurban, suburban, and urban
development in formerly rural areas. 相似文献

The focus on ‘flexible specialisation’ in the 1980s and 1990s marked an important turning point in framings of economic agency
and diversity within economic geography. This article deconstructs the ways in which subjects were framed as ‘flexible’ in
both the flexible specialisation literature and later work on the Diverse Economy (Gibson-Graham 1996, 2002, 2006), seeking out particular examples of the ways in which different projects of subjection appear to frame different views of
economic possibility. Drawing richly on a case study of residents in an inner-city neighbourhood of West End, Brisbane (Australia),
this paper uses resident’s articulations of their everyday practices to reinvigorate some of the ideas of the flexible specialisation
literature and challenge, defamiliarise and rework existing ideas of economic life in “First World”, urban contexts. 相似文献

The intent of this paper is to explore how ‘reel’ and ‘real’ landscapes can be rendered dialectic. The analysis focuses on
the filming of Tarzan's Secret Treasure (1941) at the wildlife preserve of Wakulla Springs in Florida, which was administered
by the financial tycoon Ed Ball. Using Mitchell's recent commentaries on ‘good’ and ‘bad’ dialectics as our entry point, we
offer two readings of this cinematic process. The first renders the on and off screen Wakulla Springs as ideological fodder,
serving to valorise capital, masculinity and whiteness. The second reading addresses how this place has been actively constructed
from discourses pertaining to class, gender and race, such that Wakulla exists as a series of fully relational spaces within
diverse contexts, both ‘real’ and ‘reel’. In structuring our analysis in this manner, we hope to make clear why it does indeed
matter for film geographers to acknowledge the conceptual presumptions brought to bear in the framing of the real and the
reel as objects of analysis.

This paper reviews current methods used in classifying retail outlets and areas devoted to retailing, in the geographical
and town planning literature. For retail outlets, classifications based upon types of goods sold, and types of shopping trip,
are discussed. This is followed by an analysis of modern large store development which reflects property developers' and retailers'
concerns. Areas devoted to retail uses are subdivided into unplanned ‘retail areas’ and planned ‘shopping centres’. Traditional
classifications based upon central place theory are reviewed for both of these types, and found wanting in the light of recent
changes in retail development practice and consumer behaviour. Classifications based upon physical development characteristics
and type of shopping trip are recommended. Finally, classifications of urban retail location are examined.

Ethnic Enclave Reconfiguration: A ‘new’ Chinatown in the Making 总被引:1,自引:0,他引:1
Years of past research on traditional Chinatowns were based on the assumption that Chinatown is an ethnic enclave for a single
ethnic minority, i.e. the Chinese. In recent years, one could observe significant changes over Chinatowns in terms of more
Vietnamese presence. Yet, the transition process as an object of study is much under-represented in the literature on ethnic
enclaves. Looking at ethnic business transition from Hong Kong to Vietnamese in Toronto’s Chinatown West, this paper argues
strongly that ‘multiple ethnicity’ can coexist in an enclave. For this case study, the Chinatown is being reconfigured into a ‘new’ Chinatown. Drawing upon data from the authors’ Vietnamese Business Database that covers information between
1983 and 2003, we present both spatial and temporal analyses that offer insights into how the Vietnamese businesses grow through
time. Our findings support the existence of a Vietnamization process in Toronto Chinatown West. However, its evolution is
still in an infant stage. In some aspects, the incoming Vietnamese businesses display similarities with the remaining Hong
Kong businesses. In sum, a total reconfiguration of Chinatown West in form and business nature is still unaccomplished. The
conventional enclave concept which bases on the singularity of ethnic group has to be abandoned in view of rising occurrence
of ethnic transition, particularly in this globalizing era. 相似文献

The Netherlands is part of the historic Northwest-Southeast multi-confessional culture belt according to the comparative framework
of church-state relations in Europe as recently developed by Madeley on the basis of Rokkan’s conceptual map. The aim of this
paper is to describe the development of the church-state relations in the Netherlands within this historic framework of state-formation
and nation-building, and to interpret recent challenges of its historic state-church model, such as secularisation, the rise
of immigrant religions, and general ‘de- and re-territorialisation’ tendencies. The Netherlands developed from a relatively
very tolerant polity dominated by the Calvinist Church to a ‘pillarised’ society, in which the Rome-Reformation divide (which
also had a strong geographical dimension) was institutionalised in the political system. After the 1960s, very strong secularisation
put this ‘pillarised’ system under severe pressure, but the remnants of this system offered a favourable opportunity structure
for religious newcomers (Muslims in particular), who could establish their mosques and Muslim schools relatively easily. However,
while the main Protestant churches, and even Catholic and Protestant political parties have merged, failing integration of
these newcomers in Dutch society and terrorist attacks at the global level as well as in the Netherlands encouraged a new
divide between Muslims and non-Muslims. The metropolitan areas in particular became the scene of this new divide. 相似文献

This paper juxtaposes the actual areas of settlement and settlement activities of Chinese migrants in Brisbane’s southern
suburbs since the mid-1980s, with the concomitant, ‘government planned’ construction of the city’s Chinatown as an ‘exotic,’
‘ethnic,’ and ‘cosmopolitan’ landmark. It argues that while the latter, as with Chinatowns in other Australian and world cities,
has continued to appropriate the symbols of so-called ‘Chineseness’ to sell the locale to non-Chinese, the former, in recalling
the notion of ‘ethnoburbia,’ significantly evinces actual Chinese migrants’ agency and role in place-making. In the process,
these migrants have not only established a local, ethnically meaningful environment, but also challenged the still current
metonymic Western image of the Chinese as preferring life in ‘ethnic’ urban enclaves that had its origin from early Chinese
settlement and fundamentally detached from the lives of other ethnic groups per se. Indeed greater recognition and comprehension of such locales may go a long way to illustrate that many Chinese living in
Australia today do not fit the territorial, place-based identity often associated with them in the imagination of mainstream
society. 相似文献

Erratum to: GeoJournal 62: 51–58 DOI 10.1007/s10708-005-8562-2 The erroneous version of this article was originally published in GeoJournal 62: 51–58. This amended version corrects the formatting errors which are evident in the original version.Abstract It is universally accepted that the need for defining precise lines of separation and points of contacts between states is the byproduct of the emergence of nation-states and ‘world economy’ in the nineteenth century Europe. Nevertheless, it is hard to overlook the fact that these modern notions are rooted in periods prior to the emergence in Europe of nation-states. There are indications that ancient civilizations were familiar with the notion of ‘state’ in connection with the concepts of territory and boundary. Ancient texts reveal that this basic principle existed in ancient Persian literature in respect of matters of state, territory, and boundary. Similarly, the likelihood exists that these Persian notions could have influenced Roman civilization. It is widely believed that a combination of ancient Greco-Roman and Persian civilizations is a major contributor to what culturally constitutes ‘West’. Later in the Sassanid period the inter-linked notions of state, territory, and boundary developed substantially, coming quite close to their contemporary forms. On the other hand, considering that ‘justice’ was the corner stone of ancient Persian Political philosophy, the idea that ancient␣Iranian spatial arrangement might have contributed to the evolution of the concept of democracy in the West may not be too difficult to contemplate.The online version of the original article can be found at 相似文献

Becoming the tallest building in the world in the mid-1990s, the Petronas Towers was the centre piece of an image of national
progress and development that Malaysian authorities sought to project internationally. The release of Fox Movies' Entrapment in Malaysia in May 1999 provoked political outrage and popular disappointment at the way in which the Petronas Towers in
Kuala Lumpur had been spliced alongside riverside ‘slums’ filmed in the town of Malacca some 150 km away. This paper provides
a critical reading of the spliced scene in the movie. At one level, the angry response of the Malaysian Prime Minister, Dr
Mahathir Mohamad, to the scene diagnoses a geopolitics of asymmetrical representational power. However, I show how Mahathir's
criticism of Entrapment in Malaysia was as much a defence of domestic political legitimacy (and national economic investibility) as it was ‘opposition’
or ‘resistance’ to hegemonic ‘Western’ (mis)representation. In addition, while the material and symbolic work of reimaging
Kuala Lumpur had sought to negate (neo)orientalist imaginings of ‘Asian’ cities, the controversial scene rendered visible
environmental ‘underdevelopment’ that has no place in a modern (vision of) Malaysia. Entrapment thus performed something in inducing Malaysian cities and citizens to ‘clean up’ their act, to practice ‘fully developed’
ways of seeing, being and being seen.

Mary Douglas (1993) has indicated some of the shared concerns that keep voluntary enclaves together as ‘social movements’.
The present paper describes a rather different kind of enclave politics, being concerned with the ‘new violence’ of groups
enclaved by social exclusion and force. The paper focuses on the emergence and subsequent development of dissidents in the
civil war in Sierra Leone. The RUF was at the outset a tiny but conventional guerrilla force, modelled on one of the militias
in the Liberian civil war, and seeking to overthrow a decayed neo-patrimonial ‘one-party’ regime. Gaining little popular support,
its members became marooned in forested isolation on the Liberia-Sierra Leone border. Recruits were mainly school children
seized by force and ‘converted’ through having to take part in atrocities against rural civilians. Unable to return to the
larger society on pain of summary execution, captives have had little option but to adjust to the political fantasies of a
violent and unstable leadership. They were enclaved by force. Indicating the predictive strength of Douglas' arguments about
the cultural dynamics of the enclave, the subsequent atrocity-drenched story of the RUF suggests that it is not the content
of belief that determines institutional culture but vice versa. To survive, the enforced enclave develops the concerns of
the classic ‘sect’ - a doctrinaire ‘rationality’ (expressed in crude acts of ‘subtractive’ violence), rejection of magic,
decision making by lots, preoccupation with defection, otiose leadership style. If the rest of the world is to come to terms
with violent enclave organizations such as the RUF and Algerian GIA it may have to pay more careful attention to the way enclave
institutions think. They may not respond ‘rationally’ to the kinds of incentives offered by mainstream groups organised around
hierarchical and/or individualist systems of social accountability.

Multiphase flow processes in unsaturated cohesive soils are often affected by deformation due to swelling and shrinking as
a result of varying water contents. This paper presents a model concept which is denoted ‘phenomenological’ in terms of the
processes responsible for soil deformation, since the effects of deformation on flow and transport are only considered by
constitutive relations that allow an adaptation of the hydraulic properties. This new model is validated in a detailed intercomparison
study with two state-of-the-art models that are capable of explicitly describing the processes relevant for the deformation.
A ‘numerical experiment’ with a state-of-the-art reference model is used to produce ‘measurement data’ for an inverse-modelling-based
estimation of the model input parameters for the phenomenological concept. 相似文献

We are concerned here with the notion of space as a primary condition for building social relations. From this stand, we have
created two analytical matrixes that can help us characterize two modes: that of ‘being-there-in-space’ and that of ‘being-of-the-space’;
the nomospace and the genospace. While the nomospace is characterized by ‘cold’ connotations, which are ideally defined as a result of a logical option, the genospace is mainly characterized by emotional or ‘warm’ connotations, which originate from a feeling of shared nature and common destiny.
We believe that these matrixes could help us to identify the meanings of some behaviours and, therefore, make us more capable
of interpreting many dynamics that occur in modern societies. The importance of geography is justified by the existing relationship
between these behaviours and their proper spatial form.

The subsurface Nagaur Basin in northwest Haryana and southwest Punjab hosts evaporite sequence, conformably overlain by Nagaur
red beds and grey beds. A polymictic conglomerate intervenes the Nagaur sequence and the overlying Tertiary sequence. The
focus is on the new finds of (i) distinctive ‘grey beds’ overlying ubiquitous red beds, (ii) ‘Malout conglomerate and grit’
horizon (Palaeocene-Miocene) marking an unconformity over the Nagaur Group (early Cambrian) and (iii) ‘entrapped gas and dried-up
leaves/carbonaceous flakes’ in the conglomerate unit and succeeding Tertiary rocks. Palaeoenvironmental significance has been
discussed. The Nagaur ‘red beds’ has been likened to ‘continental red beds’ of Schreiber (1978) and ‘reworked red beds’ of
Krynine (1949). The ‘grey beds’ are channel fillings, fresh material having been derived from fresh cuttings by streams/rivers
following structural grains in the Aravalli landscape where the interfluves provided weathered (oxidised) materials for the
red beds. Association of continental red beds and grey beds is known in the Newark Series (Triassic) of the Eastern United
States and the Keweenawan ‘late Precambrian’ of the Lake Superior region. 相似文献

This paper focuses on how livelihood and the question of development and environment in a globalising era should be examined.
It discusses various views in geography on the question of environment and development, and it explores the concept of sustainable
livelihood. It concludes that a geographical conceptualisation of ‘development and environment’ may profit from the discussion
on sustainable livelihood, provided that it does not become entangled in an actor-cum-local bias. Moreover, the diffusion
of non-equilibrium concepts may broaden the analysis of man-land relations and open the way to an analysis of globalisation
effects. Globalisation gives rise to new assortments of geographical entities and, as livelihoods adapt, they will shape constantly
shifting regions with specific man-land arrangements.

A comparative analysis of several vulnerability concepts 总被引:2,自引:0,他引:2
A comparative analysis of six vulnerability models aims to identify differences and similarities between several approaches
towards understanding vulnerability. The analysis yields a set of characteristics for explaining the condition of vulnerability
(multiple contexts, multiple dimensions, temporal variability, multiple scales and scale-interdependency). In addition, ‘adaptation’
and ‘adaptive capacity’ are identified as key elements of vulnerability. The results of the analysis are put into a wider
context not only of vulnerability but also of resilience and risk research. It is demonstrated that ‘adaptation’ and ‘adaptive
capacity’ serve as hinges not only for conceptualising vulnerability but between ‘vulnerability’ and ‘resilience’ alike. Based
on the results of the comparative analysis, a model of vulnerability focussing on the household and community scale is developed,
which displays the key findings of this work. 相似文献

Memorial landscapes: analytic questions and metaphors 总被引:1,自引:0,他引:1
Over the past two decades, geographers have probed the intersection of collective memory and urban space. Their sustained
interest in the subject reflects an understanding of the social condition of commemoration and the important role that space
plays in the process and politics of collective memory. Along with other critical social scientists, geographers envision
these public symbols as part of larger cultural landscapes that reflect and legitimate the normative social order. A review
of the extant literature indicates that geographers scrutinize memorial landscapes through three conceptual lenses that may
be understood via the metaphors of ‘text,’ ‘arena,’ and ‘performance.’ These metaphors are in turn mobilized through a series
of analytic questions that serve to identify the interests served and denied by landscape ‘texts,’ the ‘arenas’ in which they
are produced, and the ways in which they are enacted via ‘performance.’ This article’s synopsis of the subfield’s predominant
metaphors and its attendant questions contributes to the ongoing cultural geographic project of articulating and implementing
methods for interpreting landscapes as open-ended symbolic systems.

War on Terror,work in progress: security,surveillance and the configuration of the US workfare state
This paper evaluates the impact of recent shifts in the geopolitical outlook of the United States—specifically the ‘Global
War on Terror’ and its domestic ramifications—on the prior project of reconfiguring the US state to an after-Fordist ‘workfare’
paradigm. In particular, the paper attempts to situate recent developments in the reconfiguration of the American welfare
state within the context of debates over the ‘exceptional’ nature of US politics post-9/11. The extent to which this has had
a bearing on work practices, welfare provision and workfarism is investigated, citing examples from the post-9/11 era. On
the basis of such examples it has been suggested that the project of reconfiguring the US welfare state and labour relations
does overlap and intersect with the emergency practices that the US state has instituted domestically as part of the War on
Terror. However, the reconfiguration of the US welfare state towards a neoliberal or workfarist paradigm is, we argue, largely
part of the ‘normal’ (as opposed to exceptional) fabric of US politics. The project of reconfiguring the US welfare state
is ongoing and largely autonomous (although not entirely removed) from the use of exceptional practices in relation to the
US security state. Investigation of this relationship, we assert, provides a potentially fruitful ‘new direction’ for both
critical geopolitics and political economic geography, and grounds for interaction between the two. 相似文献
