Recent developments in spatial analysis and spatial data have allowed researchers to investigate various geographical factors in the quantitative analysis of conflict and war (Ward in Polit Geogr 21(2):155–158, 2002). Despite the importance of territory in interstate conflict, there has been a limited interest in the application of spatial analysis to the study of territorial conflict. Using geographically weighted regression (GWR) we evaluated the existing explanations of territorial conflict provided by a global scale analysis that assumes a spatial consistency in the explanatory variables. Specifically, we revisited Paul Huth’s foundational work by using GWR to examine the spatial pattern in the sign and significance of the variables. The result of GWR shows that the escalation of territorial conflict cannot be fully explained by one universal model. There is a high level of spatial variation in the regression parameters and the explanatory power of the model varies over space. A k-means cluster analysis was implemented for a further investigation of the regional pattern of the underlying causes of territorial disputes. The result of our GWR suggests the necessity and possibility to pursue a local or regional scale approach to the study of territorial conflict, an approach that challenges an epistemology of seeking a single explanation for the causes of conflict that neglects regional context. The spatial heterogeneity in the causes of territorial conflict escalation we find is framed within a narrative of the intertwined processes of colonialism, Cold War legacies, and competition for resources.  相似文献

States employ international economic institutions as formal mechanisms in resource related conflict management. It is little known that states incorporate water resource management treaties in regional trade agreements (REIs) to jointly manage (1) the multifaceted use of rivers and (2) the territorial implications of rivers as borders. Both can lead to political tensions. I evaluate institutional effectiveness, through REI institutional design, in militarized interstate conflict. The role of trade institutions in geo-politics is a broad theme addressed. African dyads, REIs and conflict from 1950 to 1996 are the focus. I test the liberal hypothesis that institutions diminish the likelihood of militarized interstate conflict. Findings suggest allies that share memberships in REI water treaties with provisions for territorial boundary issues are more likely to fight than are other states. This relationship is weak, however, lending support to realist claims.  相似文献

Research of the interrelation between regional planning, division into economic districts and urban-planning, division into economic districts and urban planning is here emphasised. In the USSR development of a network of territorial economic complexes, economic districts including subregions of the II and III order, economic subregions and microdistricts is continuous. The outlook of regional planning is defined by the elaboration of its scientific theory including the geographical concept of regional planning. The use of geographical methods widens the scientific basis for the development of a systems approach and improves forecasting, the choice of aims and strategy of developing production, population distribution and the solution of ecological problems. The efficiency of regional planning depends not only on purely economic advantages, but on a more sensible use of nature. Regional planning is concerned with bio-economic systems, and must avoid conflict between the most important subsystems, natural and anthropogenic. Preservation of ecological balance has become the most important task of regional planning. When locating industrial enterprises in the process of regional planning, ecological factors are taken into account to an ever-increasing degree. The main tasks of regional planning concerning the distribution of agriculture stem from the aim of interrelated development of all elements of the agrarian and industrial complex. During the scientific and technical revolution the distribution of production orientates more and more and not towards individual towns but towards a system of populated areas. Systematic improvement of conurbations and their transformation into group systems of populated areas, regulated according to plan and having a broader economic and territorial base, are the most important task of regional planning and urban development.  相似文献

The political and economic upheavals during the past two decades have led to a new social and political organization of space on all levels of scale. To deal with the obvious changes, political geography had to rethink and to extend its traditional concepts. Transcending its long taken-for-granted radical approaches, the Anglo-American geography developed two conceptional paths, both of which are still relevant for political geography today:— a new awareness of regional differences in political action and culture— a new, constructionist awareness of the instrumentalization of geographical discourses for geopolitical purposes.With these theoretical concepts, political geography is examining a number of both traditional and new fields of research. Their heterogeneity is once again evidence of postmodern diversity and difference. They are characterized by both a new awareness of differentiation and a widening of the traditional viewpoint in three closely related respects transcending the traditional topics of political activity, the traditional political actors and the established levels of scale of politics. Based on the current literature it is possible to outline some major themes and perspectives of current political geography that are closely linked together, like knots in thematic networks:1. ecological politics and resource conflicts 2. territorial conflicts and boundaries 3. geopolitics and the politics of identity 4. globalization and new international relations 5. the symbolic representation of political power 6. regional conflicts and new social movements.  相似文献

Until recently the traditional spatial configuration of the European geography was based upon the core-periphery model. The ‘pentagon’, broadly defined as lying between London, Paris, Milan, Munich and Hamburg, was seen as the core area characterised by having the highest concentration of economic development in the European Union (EU), with the remainder of the European territory viewed as peripheral, albeit to varying degrees. In a number of cases such peripheral areas equated with clear regional disparities. The elaboration of the European Spatial Development Perspective (ESDP) (CEC, European spatial development perspective, towards balanced and sustainable development in the territory of the European Union, 1999) challenged this core-periphery model. European spatial planning policies, aimed at encouraging social and economic, and with ever increasing importance, territorial cohesion, seek amongst other aspects to encourage the development of a balanced and polycentric urban system. This paper adopts a network analysis approach to the analysis of air passenger flows between some 28 principal European metropolitan urban regions. The evaluation of these flows contributes to an enhanced comprehension of the spatial dynamics of the European metropolitan territory which goes beyond that deriving from the more standard analyses of the individual components of the urban system. Several indicators are used, deriving from gravitational modelling techniques, to analyse the complexity of the air passenger flows. A multidimensional scaling (MDS) technique is introduced in order to interpret and visualise the resulting spatial configuration and positioning of the different metropolitan centres within the conceptual European ‘space of air passenger flows’, thereby contrasting with the more traditional map-based geographical image of Europe, based upon Cartesian coordinates.

Over the past few decades, intense urban expansion has occurred over the Campi Flegrei territorial system without considering the volcanic risk. In this active volcanic area, where a short period evacuation could be necessary, the emergency management cannot be based solely on hazard-related information. The territorial and social features must also be considered. In this framework, the main purpose of this research is to point out the seriousness of the present setting of the Campi Flegrei territorial system in case an evacuation is necessary. Following the concept of regional evacuation, the zone to be involved in emergency planning was identified as the whole of the area threatened by the volcanic events of the past 10?ka. Inside this area the spatial relation between the resident distribution and the outflows of roads, railway stations and harbours, to facilitate evacuation, was investigated. A spatial relational GIS-based procedure was used to draw the territorial system vulnerability map, depicting the zones with different capabilities to support the evacuation of residents in case of volcanic activity. Based on the concept that people could leave the dangerous area by the means of transport supplied by Civil Protection, and using the threshold value of over-crowding of 0.70 people/m2, we identified the collection areas for residents to be immediately evacuated in case of volcanic unrest, and five macrozones displaying different capabilities to cope with an emergency phase.  相似文献

We conducted a study of the spatial distributions of seismicity and earthquake hazard parameters for Turkey and the adjacent areas, applying the maximum likelihood method. The procedure allows for the use of either historical or instrumental data, or even a combination of the two. By using this method, we can estimate the earthquake hazard parameters, which include the maximum regional magnitude Mˆmax, the activity rate of seismic events and the well-known bˆ value, which is the slope of the frequency-magnitude Gutenberg-Richter relationship. These three parameters are determined simultaneously using an iterative scheme. The uncertainty in the determination of the magnitudes was also taken into consideration. The return periods (RP) of earthquakes with a magnitude M ≥ m are also evaluated. The whole examined area is divided into 24 seismic regions based on their seismotectonic regime. The homogeneity of the magnitudes is an essential factor in such studies. In order to achieve homogeneity of the magnitudes, formulas that convert any magnitude to an MS-surface scale are developed. New completeness cutoffs and their corresponding time intervals are also assessed for each of the 24 seismic regions. Each of the obtained parameters is distributed into its respective seismic region, allowing for an analysis of the localized seismicity parameters and a representation of their regional variation on a map. The earthquake hazard level is also calculated as a function of the form Θ = (Mˆmax,RP6.0), and a relative hazard scale (defined as the index K) is defined for each seismic region. The investigated regions are then classified into five groups using these parameters. This classification is useful for theoretical and practical reasons and provides a picture of quantitative seismicity. An attempt is then made to relate these values to the local tectonics.  相似文献

The territorial dimension of the digital divide is usually considered as a phenomenon that penalizes the peripheral regions, especially in terms of regional economic development. Taking into account the territorial networking of ICT (Information & Communication Technologies) infrastructures—particularly high-speed networks—provides what is probably the principal reason for such a perception. This is particularly true considering that the most-peripheral regions and those with the smallest population densities are also the poorest in terms of ICT infrastructures. In Western countries, however, the digital divide is no longer the result of network-related problems. Nowadays, the issue of the skills required to adequately exploit the potential of ICT is at the forefront. Yet this evolution is likely to lead to an inversion of the inequalities between the centre and the periphery, as populations without such skills—recent immigrants, the unemployed, the illiterate, people with little education or on low incomes and other socially marginalized people—are generally concentrated in urban centres. Consequently, the priority for reducing inequalities of access to ICT resources is no longer the provision of high-performance ICT infrastructures for peripheral regions, but rather the implementation of continuing education and social action policies within the urban centres.  相似文献

Agglomeration areas in the GDR are those regions, which are characterized by an above average level of regional concentration of productive forces and their conditions of reproduction. The economic potential concentrated in these regions represents a large part of the national economy. It is possible to describe the territorial structure of these agglomeration areas by general indices (agglomeration core — agglomeration field — agglometation fringe; polycentric node-band-structure), but also the individual features of each one of these regions are to be attended. They are expressed for the first time by several forms of localization of plants and by the structure of settlements and settlement networks. The present main tendencies in the development of the agglomeration regions are:
  • They succeeded in minimizing the regional disparities of productivity between different agglomeration regions and within them, and in stabilizing the economic position of these regions by systematic measures for investment and rationalization and the hereby influenced structural changes.
  • At present and up to 1990 the completion of housing programme is of foremost importance by which the main activities will shift from the urban fringe to the centres of the cities; provincial towns and smaller settlements will also participate in this programme.
    • The main target of these activities is to remove imperfect structures and other burning problems of the agglomeration regions step by step. Geographical Institutes are dealing with the management of these tasks too.  相似文献

    The role of economic sectoral structure in regional growth and development is widely acknowledged. However, there has been scarce reflection on its role as a policy instrument, particularly for peripheral regions. In reaction, this paper investigates the role of economic sectoral structure as a policy instrument towards more resilient peripheral regions. Through a multiple country policy analysis, the paper determines to what degree economic sectoral structure is reflected in regional development policies of 18 countries with predominantly rural characteristics and lagging regions. Moreover, the role of economic sectoral structure towards more resilient regions is quantified and measured for a specific peripheral region case in South Africa as developing country exhibiting poor economic resilience. The paper highlights related variety as a key ingredient for a region to reach a state of dynamic stability between adaptation and adaptability towards enhanced long-term resilience capacity of the peripheral region. The research concludes that policy focus should support the maintenance of the sectors and industries of comparative advantage on the regional scale, but strongly focus on sectoral comparative advantage within the national scale (if present) to establish a more robust region. This will establish and strengthen the identified peripheral growth centres as centres of national competitiveness and specialisation. Primary policy actions as emanated from the literature and the multiple country policy analysis will promote more efficient sectoral composition as key towards more resilient peripheral regions. It is acknowledged that these policy actions must be informed by a detailed regional economic analysis for different peripheral regions to determine inherent and latent economic potential and link with interdependent industries. This paper will highlight that regional policy should become more explicit by exploiting the role of economic and natural resources as growth engines for the peripheral regional economy in a more effective way through a multi-centred territorial structure.

    Spring deposits reveal the timing and environment of past groundwater discharge. Herein, however, the potential for fossil spring deposits to infer water sources and palaeoflowpaths through trace elements and stable and radiogenic isotopes is examined. Past discharge (70 to 285 ka) in the Tecopa Basin in the Death Valley region of southeastern California is represented by tufa deposits, including mounds, pools, cemented ledges and rare calcite feeder veins. δ18O values indicate that spring discharge was a mixture of far‐travelled (regional) water with a significant, and perhaps dominant contribution of local recharge on a nearby range front and alluvial pediment, rather than simply representing an elevated regional water table. δ13C values indicate regional water had a high TDS, whereas solute data imply low overall solute contents, consistent with dilution by a large component of local recharge. Radiogenic isotope data (U‐series, 87Sr/86Sr) for tufa indicate that siliciclastic rocks (a regional aquitard) interacted with discharging water. To access this aquitard, regional flow was probably partitioned into a permeable north–south damage zone of a north–south range‐bounding fault along the foot of the Resting Spring Range, which ultimately controlled the location of groundwater discharge. Existing models for modern discharge in the Tecopa Basin, by contrast, call upon westward interbasin flow in carbonate rocks from the Spring Mountains through the intervening (and nearly perpendicular) Nopah and Resting Spring Ranges. Understanding the controls on regional groundwater flow is critical in this and other arid regions where water is, by definition, a scarce resource. Thus, although it is a case study, this report highlights a fruitful approach to palaeohydrology that can be widely applied. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

    Territorial symbolism in sub-Saharan Africa calls to mind multiple forms of knowledge. More particularly, territorial significance is fed both by magical and sacred beliefs and by knowledge based on empirical observation and concrete practices. These two types of knowledge differ widely as to their nature, the procedures by which they are formed, and the cultural values they embody. Nevertheless, semantic interaction between mythical knowledge and technical knowledge is remarkably rich. By blurring the distinction between mythos and techne, this semantic interaction seems to constitute an important cultural tool for building feelings of social security in that it reinforces and stabilizes socio-geographic patterns, and more especially those which regulate access to space and natural resources. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

    The aim of this paper is to provide an overview of developments in Croatia related to boundary and territorial issues in the aftermath of the disintegration of Yugoslavia. This survey will therefore detail key events including the Serbo-Croatian war of 1991, the uprising of the Serbian minority, international mediation efforts, the deployment and operation of UN forces in Croatia and Croatia's territorial consolidation in 1995. In the aftermath of Operations Flash and Storm in May and August 1995, respectively, and the spectacular gains by combined Croat and Bosnian forces in western Bosnia in September 1995, Croatia's strategic outlook has been transformed. There are, however, several outstanding issues and disputes yet to be resolved and these will be outlined.  相似文献

    The Mellish Park Syncline is located in the northern part of the Mt Isa terrane. It has an axial trace that transects the remnants of the unconformity‐bounded Palaeoproterozoic Leichhardt and Isa Superbasins. The syncline is separated into a lower and upper component based upon variation in fold geometry across the basin‐bounding unconformity. The lower syncline, in the Leichhardt Superbasin, is tight and has an inclined west‐dipping axial plane. The upper syncline, in the Isa Superbasin, is open and upright. The geometry of the lower syncline is a consequence of a period of shortening and basin inversion which post‐dated the Leichhardt Rift Event (ca 1780–1740 Ma) and pre‐dated the Mt Isa Rift Event (ca 1710–1655 Ma), forming an open and upright north‐oriented syncline. Subsequent southeast tilting and half‐graben development during the Mt Isa Rift Event resulted in the lower syncline being tilted into its inclined geometry. Sequences of the Isa Superbasin were then deposited onto the eroded syncline. The geometry of the upper syncline reflects regional east‐west shortening during the Isan Orogeny (ca 1590–1500 Ma). The position of the upper syncline was largely controlled by the pre‐existing lower syncline. At this time the lower syncline was reactivated and tightened by flexural slip folding.  相似文献

    The Quebec-Canada problem arises some ambigious and contradictory issues with Quebec itself being the source of the current facets of the crisis. Political geography is able to contribute to a greater understanding of the crisis by clearly demonstrating some of the classig concepts drawn from the discipline: geography of federalism, political viability and centrifugal forces, ethnic separatism, territorial integrity and linguistic territoriality, nationalism, and regionalism, territorial ideology, international frontiers... Evermore, Quebec appears to be the unique case of a national state. The gravitation of Canada's population towards the West has a direct impact upon the Quebec situation, with the eventual independence of the Province bringing about ipso facto a Pakistanisation of the country as a whole. Currently, one may observe an ever-widening lack of communication between Quebec and the rest of Canada. In order that Europeans (and many others) may fully understand the Quebec situation, a sort of mental debriefing must take place.  相似文献

    Urban settlements of regional importance from Romania impose within the national settlements system by their ability to converge material and human flows, leading to important unbalances in the relationships between the components of territorial systems. The status they held, both in the communist period and at present, made the economic activities developed in a short time exceed the adapting ability of the other components of the territorial system, the natural environment strongly feeling the industrialisation pressure. Identifying the specificities of the environmental risk management at the level of development poles of regional importance was done by detailed analyses accomplished in Craiova, a representative town for the high concentration of economic activities strongly pressing upon the natural environment. The construction of the model of environmental risk management supposes the classifying of risks by a series of criteria, a model which constitutes a useful instrument for the decision factors. The management of unbalances from the territorial systems determined by industrialisation is one of the major preoccupations of the decision factors from Romania, in order to be aligned to the European environment standards.  相似文献

    A sequence of psammitic and pelitic metasedimentary rocks from the Mopunga Range region of the Arunta Inlier, central Australia, preserves evidence for unusually low pressure (c. 3 kbar), regional‐scale, upper amphibolite and granulite facies metamorphism and partial melting. Upper amphibolite facies metapelites of the Cackleberry Metamorphics are characterised by cordierite‐andalusite‐K‐feldspar assemblages and cordierite‐bearing leucosomes with biotite‐andalusite selvages, reflecting P–T conditions of c. 3 kbar and c. 650–680 °C. Late development of a sillimanite fabric is interpreted to reflect either an anticlockwise P–T evolution, or a later independent higher‐P thermal event. Coexistence of andalusite with sillimanite in these rocks appears to reflect the sluggish kinematics of the Al2SiO5 polymorphic inversion. In the Deep Bore Metamorphics, 20 km to the east, dehydration melting reactions in granulite facies metapelites have produced migmatites with quartz‐absent sillimanite‐spinel‐cordierite melanosomes, whilst in semipelitic migmatites, discontinuous leucosomes enclose cordierite‐spinel intergrowths. Metapsammitic rocks are not migmatised, and contain garnet–orthopyroxene–cordierite–biotite–quartz assemblages. Reaction textures in the Deep Bore Metamorphics are consistent with a near‐isobaric heating‐cooling path, with peak metamorphism occurring at 2.6–4.0 kbar and c. 750–800 °C. SHRIMP U–Pb dating of metamorphic zircon rims in a cordierite‐orthopyroxene migmatite from the Deep Bore Metamorphics yielded an age of 1730 ± 7 Ma, whilst detrital zircon cores define a homogeneous population at 1805 ± 7 Ma. The 1730 Ma age is interpreted to reflect the timing of high‐T, low‐P metamorphism, synchronous with the regional Late Strangways Event, whereas the 1805 Ma age provides a maximum age of deposition for the sedimentary precursor. The Mopunga Range region forms part of a more extensive low‐pressure metamorphic terrane in which lateral temperature gradients are likely to have been induced by localised advection of heat by granitic and mafic intrusions. The near‐isobaric Palaeoproterozoic P–T–t evolution of the Mopunga Range region is consistent with a relatively transient thermal event, due to advective processes that occurred synchronous with the regional Late Strangways tectonothermal event.  相似文献
