An Anatomy of Spatial Planning: Coming to Terms with the Spatial Element in UK Planning

“Spatial planning” is a phrase that now resonates throughout many planning systems across the globe. It is being used as a label to describe pan-national, regional, strategic and even aspects of local planning processes. Within the UK, spatial planning is being utilized alongside, or even in place of, more traditional phraseology associated with planning, such as “town and country planning”. It is being used by a range of institutions of the State, professional groups and academic commentators to describe the processes of planning reform, modernization, policy integration, and strategic governance that politically are now required to make planning fit for purpose in the 21st century. The precise meaning and definition of spatial planning remains difficult to pin down, as does its origins within the UK. This paper attempts to dissect the various components of the spatial planning phrase and set out the meaning and origins of the term in the UK context. It covers re-territorialization, Europeanization and integration origins of spatial planning thinking and provides a conceptual, rather than practical, debate on the anatomy of spatial planning, situated within ongoing processes of institutional transformation, through the lens of governance and distinctiveness in state policy development.     

Comparing expeditious procedures for the seismic vulnerability assessment on the European territorial context: reliability,feasibility, cost,and time consumption

ABSTRACT

The definition of strategies for the preservation and protection of cultural heritage is a topical issue, especially in view of the increasing relevance of the theme of seismic risk mitigation and reduction.

The prediction of the impact an earthquake could have on existing buildings requires the knowledge of their dynamic behaviour. The procedure to be adopted for this purpose is quite complex and onerous in terms of costs, time, and implementation, especially when the study concerns territorial areas rather than single buildings. The definition of methodologies aimed at respecting the principles of economic sustainability and preserving human life and architectural heritage is of paramount importance to assess seismic vulnerability using available resources. Rapid methods for the seismic vulnerability assessment, aimed at defining buildings vulnerability and intervention priority lists, must be implemented to guarantee the preservation of historical centers.

This article describes the application to some case studies of different methods aimed at creating fragility curves for the vulnerability assessment on the European territorial context. The comparison between a deterministic approach and a new probabilistic one is performed for all case studies, to define the most suitable methodology in terms of reliability and savings in cost and time.     

‘Land of Fires’: Urban Growth,Economic Crisis,and Forest Fires in Attica,Greece

This study investigates the spatial distribution and basic characteristics of 2692 forest fires between 2000 and 2011 in Attica, Greece, a rapidly expanding urban region. Fire variables were assessed, together with variables describing the socio‐economic local context in three distinct periods of Athens’ expansion (2000–2003: semi‐compact expansion and economic growth before the 2004 Olympic Games; 2004–2007: infrastructure development and discontinuous expansion following the Olympic Games; 2008–2011: crisis‐driven decline of the construction industry). Fire characteristics changed over the three periods following the negative trends in the construction industry. Burnt areas decreased in the rural area around Athens and the opposite pattern was observed in the peri‐urban belt. Our findings suggest that the temporal and spatial distribution of forest fires in Attica reflects the construction boom stimulated by the 2004 Olympic Games and the subsequent economic crisis.     

The Role of Fire Disturbance on Runoff and Erosion Processes – a Long‐Term Approach,Mt. Carmel Case Study,Israel

The Mediterranean ecosystem of Mt. Carmel, Israel, is subjected to an increasing number of forest fires of various extents and severities. The impacts of forest fires on runoff and erosion are widely documented and include increased peak flows and soil loss until the return of a vegetation cover. Most studies, however, treat fire as a single event, whereas the present study is aimed at exploring the long‐term effects of repeated forest fires on eco‐geomorphic processes. The study integrates the results of plot‐based, detailed analysis of post‐fire runoff and erosion with vegetation recovery analysis, at a temporal‐spatial scale which includes the effect of reburning. Our results indicate that forest fires lead to a significant increase in runoff and sediment yields, particularly during the first two years following the disturbance, up to five orders of magnitude higher than from the adjacent unburnt control plots.     

Seismic vulnerability assessment methodology for slender masonry structures

ABSTRACT

Slender masonry structures such as towers, minarets, chimneys, and Pagoda temples can be characterized by their distinguished architectural characteristics, age of construction, and original function, but their comparable geometric and structural ratios yield to the definition of an autonomous structural type. These structures constitute a part of the architectural and cultural heritage. Their protection against earthquakes is of great importance. This concern arises from the strong damage or complete loss suffered by these structures during past earthquakes. Seismic vulnerability assessment is an issue of most importance at present time and is a concept widely used in works related to the protection of buildings. However, there is few research works carried out on developing the seismic vulnerability assessment tools for such structures.

This article presents a new method for assessing the seismic vulnerability of slender masonry structures based on vulnerability index evaluation method. The calculated vulnerability index can then be used to estimate structural damage after a specified intensity of a seismic event. Here, 12 parameters are defined to evaluate the vulnerability index for slender masonry structures. Implementation of this methodology is carried out in different types of slender masonry structures to develop vulnerability curves for these structure types.     

Map Resolution and Spatial Autocorrelation

Moran's I, a measure of spatial autocorrelation, is affected by map resolution and map scale. This study uses a geographic information system (GIS) to examine the resolution effects. Empirical distribution of wildland fires in Idyllwild, California, and hypothetical distributions of ordered patterns are analyzed. The results indicate that Moran's I increases systematically with the resolution level. The resolution effects can be summarized by a log-linear function relating the I coefficients to resolution levels. Empirical tests that compare the distribution of fire activity in a vegetation map and in a topographic map confirm the resolution effects observed.     

Disease, Social Identity, and Risk: Rethinking the Geography of AIDS

The emergence of new diseases and the re-emergence of 'old' diseases necessitates a relook at what shapes vulnerability to ill health. A framework is proposed that combines a realist approach to mapping vulnerability with feminist and post-structural approaches that focus more attention upon the role of social identities and cultural framings of disease. Too often investigations of disease focus either upon structural determinants of risk such as political policy and the economy, or on discursive definitions of disease that impact its experience. A combination of these approaches would result in a more effective framework for evaluating vulnerability, and subsequently for generating effective disease prevention strategies. The social, economic, political, and cultural context of HIV/AIDS in Malawi is given as an illustration of this framework.

A New Perspective about Moran's Coefficient: Spatial Autocorrelation as a Linear Regression Problem. Moran系数的新视角：空间自相关视为线性回归问题

The computation of Moran's index of spatial autocorrelation requires the definition of a spatial weighting matrix. The eigendecomposition of this doubly centered matrix (i.e., one that forces the sums of all rows and columns to equal zero) has interesting properties that have been exploited in various contexts: distribution properties of the Moran coefficient (MC), spatial filtering in linear models, generalized linear models, and multivariate analysis. In this article, this eigendecomposition is used to propose a new view of MC based on its interpretation in the simple context of linear regression. I use this interpretation to demonstrate the different properties of MC and also the inefficiency of this index in some situations involving simultaneous positive and negative spatial autocorrelation. I propose some new statistics and procedures for testing spatial autocorrelation, and conduct a simulation study to evaluate these new approaches.     

The role of zoning in the strategic planning of protected areas: lessons learnt from EU countries and Serbia

This paper aims to highlight the problems and possibilities for improving the nature protection zoning of protected areas (PA) in spatial planning. It analyses and compares the systems of spatial planning and the legal basis for protecting nature in PAs in selected EU countries and Serbia. It investigates and compares the role of nature protection zoning and the practice of spatial planning for selected European countries. The case study of a national park in each of the selected countries is used to analyse the nature protection zoning and its role in the coordination of spatial planning for PAs and their surroundings. The initial hypothesis is tested and confirmed that, regardless of differences in the planning systems of the selected European countries, the models of nature protection zoning established for PAs are defining for the coordination of planning instruments in achieving the protection and sustainable development of PAs. The lessons learnt concern the identification of similarities and differences in approaches to nature protection zoning, and their relationship with the spatial planning for PAs in six European countries. Based on these lessons and existing research, recommendations are given for improving the legal basis for the nature protection zoning and spatial planning of PAs in Serbia.     

On exposure,vulnerability and violence: Spatial distribution of risk factors for climate change and violent conflict across Kenya and Uganda

Recent studies discuss the link between climate change and violent conflict, especially for East Africa. While there is extensive literature on the question whether climate change increases the risk of violent conflict onset, not much is known about where a climate-conflict link is most likely to be found. We address this question by analyzing the spatial distribution of the factors commonly associated with a high exposure and vulnerability to climate change, and a high risk of violent conflict onset in Kenya and Uganda. Drawing on recent literature and quantitative data for the period 1998–2008, we develop various specifications of a composite risk index (CRI) with a spatial resolution of half a degree for Kenya and Uganda in the year 2008. A quantitative comparison with conflict data for the year 2008 provides support for the composite risk index. Finally, the composite risk index is contrasted with the findings of three qualitative case studies, which provide mixed support for the index and help to identify its strengths and weaknesses as well as conceptual needs for further quantitative studies on climate change and violent conflict.     

Forest as hazard,forest as victim: Community perspectives and disaster mitigation in the aftermath of Kelowna's 2003 wildfires

Situated within the political ecology of hazard, this article is an extended case study of the devastating 2003 wildfires in and around Kelowna, British Columbia (also known as the Okanagan Mountain Park Fire). This article reveals how compliance (or lack thereof) with fire mitigation strategies recommended by provincial, regional, and municipal agencies is complicated by differing social constructions of what constitutes ecologically sustainable forest management and community safety. Three perspectives emerge regarding the urban forests: “nature as hazard”—a volatile force to be controlled; “nature as instrumentally valuable”—a contribution to the character of one's surroundings and subsequent sense of place; and “nature as intrinsically valuable”—a distinct entity to be preserved and protected for its own sake. The article also examines how experiences of disaster influence community perceptions and result in a greater willingness to engage in fire mitigation strategies due to perceptions of heightened vulnerability. Forestry and fire mitigation agencies need to determine multiple courses of action among the varied and valid range of residents’ nature perspectives. The role of human agency in disaster mitigation must be examined, particularly as the risk of fire at the wildland‐urban interface continues to be exacerbated by encroaching human settlements and climate change.     

Increasing Societal Discomfort About a Dominant Restrictive Planning Discourse on Open Space in Flanders,Belgium

The specific spatial context in the densely urbanized northern part of Belgium, Flanders, offers a sort of laboratory conditions to study, design and plan fragments of open space in an urbanizing context. A chronological analysis of documents in three periods relevant to Flemish spatial planning policy allows us to conclude that one single planning discourse has reigned spatial planning in Flanders already since the design of the first zoning plans 45 years ago. This planning discourse considers city and countryside as two separate and separated entities. Today, however, the validity of this dominant discourse is increasingly under pressure. An obvious societal need appears to be growing to turn around the perception of a possible contradiction between city and countryside. In a densely urbanized spatial context, alternative planning discourses should be based on the idea of open spaces that offer complementary services within a partnership between city and countryside.     

Developing a Synthetic Index of Land Vulnerability to Drought and Desertification

This paper develops an index of the vulnerability of land to drought and desertification (LVI) for Italy. The index takes into account changes in climate, land use, vegetation cover, soil properties, and population during the period 1990–2000. The LVI was built up through a multivariate approach aimed at assessing the importance of the various indicators included in the synthetic index. Increasing land vulnerability was observed during this time, especially in dry areas of the southern regions. This is interpreted as a consequence of land management practices, agricultural intensification, population pressure, and bio-physical degradation. The LVI can be used in an integrated, decision-support system to evaluate the impact of mitigation policies in rural environments.     

Spatial Planning Harmonisation as a Condition for Trans-National Cooperation

This paper explores a possible direction for enabling trans-national cooperation in Europe through forms of spatial planning harmonisation. The specific case considered is that of the trans-national border area located in the wider Alpine-Adriatic context, comprising Carinthia (Austria), Friuli Venezia Giulia (Italy) and Slovenia. Starting from a general analysis of spatial planning systems and identification of operational difficulties which may emerge within any one Member State's planning system—and which then may be compounded in a trans-national context—the paper considers the establishment of a “shared knowledge base” as well as a “shared vision” between the Member States as preconditions to fostering trans-national cooperation.     

Global crisis and the systems of spatial governance and planning: a European comparison

Inadequate regulation of spatial development is at the origin of the current global crisis and increases, in years of crisis, the unequal distribution of wealth. The importance of the related risks for democracy draw attention to the systems of spatial governance and planning, through which States regulate spatial development. In Europe, the countries most affected by the unequal effects of the crisis have spatial planning systems that are traditionally based on the preventive assignation of rights for land use and development through a plan. The systems of other countries had established beforehand that new rights for land use and for spatial development are rather assigned only after the public control of development projects and their distributional effects. Despite the evidence that some models can operate better than others in ensuring public government of spatial development, the improvement of spatial planning systems is, however, limited by their complex nature of ‘institutional technologies’. Especially in a context of crisis, planners are responsible for the increase in public awareness concerning the role of spatial governance in economic and social life.

A Multiobjective Approach to Locate Emergency Shelters and Identify Evacuation Routes in Urban Areas

Evacuation planning is an important component of emergency preparedness in urban areas. The number and location of rescue facilities is an important aspect of this planning, as is the identification of primary and secondary evacuation routes for residents to take. This article introduces a multiobjective approach to identify these aspects of evacuation planning. The approach incorporates a multiobjective model into a geographical information systems–based decision support system that planners can access via the Internet. The proposed approach is demonstrated with a case study for the City of Coimbra, Portugal, for evacuation during major fires. Although presented in this context, this approach is applicable to other emergency situations such as earthquakes, floods, and acts of terrorism.
