Impacts of Planners' Different Viewpoints on Optimum Land-Use Allocation

Development of different viewpoints/perspectives in the planning process and discussion of their empirical results will allow creation of “better land-use plans”. In this sense, one of the deficiencies met by the land-use planners is lack of decision support system that can analyse the empirical results of different viewpoints analytically. The aim of this study is to analyse impacts between planners' different viewpoints and the optimum land-uses allocation empirically and analytically. The study uses a generalized land assignment model formulated by Hanink and Cromley (1998) [Land-use allocation in the absence of complete market values, Journal of Regional Science, 38(3), pp. 465–480] that integrates the geographical information systems with multi-criteria decision-making techniques in Cesme/Izmir in Turkey. The study results indicated that the model is very useful to analyse impacts between planners' viewpoint and optimum land-use allocation.     

In Situ Preservation of Ancient Floor Mosaics in Turkey

Abstract

As stated in the Burra Charter (1979) ‘A building or work should remain in its historical location. The moving of all or part of a building or work is unacceptable unless it is the sole means of ensuring its survival’. This statement has been neglected many times during rescue excavations in Turkey (e.g. Zeugma), whereas the destruction of ancient floor mosaics caused by lifting, especially when carried out by incompetent or inexperienced personnel at systematic archaeological excavations, has steered the authorities desire to preserve them in situ. However, due to the lack of conservation professionals and insufficient resources for conservation, it becomes a difficult issue to provide an effective preservation scheme for archaeological excavations. This paper aims to discuss this important issue in terms of the national legislation, preventative and interventive conservation approaches at various sites, exhibition and maintenance of mosaics, as well as the training of conservation technicians in Turkey.     

Conservation versus Regeneration?: Case of European Capital of Culture 2010 Istanbul

The purpose of this research is to review different perceptions on the possible future role and impact of the European Capital of Culture (ECoC) 2010 Istanbul in enabling conservation to contribute to regeneration. The paper attempts to understand the vicious relationship between conservation and regeneration and it analyses the ways in which the ECoC event can resolve potential contradictions enabling conservation to contribute to regeneration by constructing an empirical study based on interviews and documentary research. It concludes with specific remarks in the name of attaining more effective and sustainable outcomes from the process both for Istanbul and Turkey.     

Serbian Spatial Planning among Styles of Spatial Planning in Europe

The classification of spatial planning styles in Europe has been successively reviewed a few times. Most recently, it has been done in the framework of the European Spatial Planning Observatories Network (ESPON) 2.3.2 project dealing with the territorial governance. Based on national overviews for 29 European countries, this project uses the classification of spatial planning systems in four styles: comprehensive-integrated, regional-economic, land-use and urbanism. This study did not take into account the spatial planning system in Serbia since it is neither in the European Union nor a member of the ESPON similar to Norway and Switzerland. This article uses the form of national overviews elaborated for the ESPON project and puts Serbia in a comparative spatial planning perspective, classifying it between the comprehensive-integrated and land-use planning styles.     

Searching for a Balance Between Community Needs and Conservation Policies in Historic Neighbourhoods of Istanbul

Despite the recent rising interest in sustainability and community-related issues among urban regeneration policy-makers, it is still questionable how far the recent regeneration efforts in historic housing areas achieve a balance between the community needs and conservation policies. To answer this question, this article explores the interplay between conservation, community needs and sustainability in the context of Turkey, focusing on Istanbul. It premises on the assumption that finding the balance between the needs, aspirations and concerns of local communities and the conservation of the built environments will lead to more equitable and sustainable solutions to the problems Istanbul historic quarters are facing. The article explains the interrelation between sustainability, community needs and conservation, investigates whether these notions have been integrated into the urban conservation policy agenda of Turkey or not and then examines the assumption above by focusing on the recent regeneration story of Fener and Balat (F&B), a declining neighbourhood in the historic peninsula of Istanbul. Debating on the strengths and weaknesses of the recent conservation-led regeneration programme, the article gives clues for future regeneration initiatives to achieve a sustainable balance between the conservation and community needs policies in historic neighbourhoods of Istanbul.     

Tourism–conservation enterprises as a land-use strategy in Kenya

Since the early 1990s, nature conservation organizations in Eastern and Southern Africa have increasingly attempted to integrate their objectives with those of international development organizations, the land-use objectives of local communities and the commercial objectives of tourism businesses, in order to find new solutions for the protection of nature and wildlife outside state-protected areas. The increased inclusion of the market in conservation initiatives has led to diverse institutional arrangements involving various societal actors, such as private game reserves, conservancies and conservation enterprises. The Koija Starbeds ecolodge in Kenya – a partnership between communities, private investors and a non-governmental organization – serves as a case study for emerging institutional arrangements aimed at enabling value creation for communities from nature conservation. Based on a content analysis of data from individual semi-structured interviews and focus group interviews, as well as a document and literature review, this article reveals a range of benefits for community livelihood and conservation. It also identifies a range of longer term governance challenges, such as the need to address local political struggles, the relations between partners and transparency and accountability in the arrangement.     

The Cultural Economy of Soil and Water Conservation: Market Principles and Social Networks in Eastern Burkina Faso

Soil and water conservation interventions in Africa have had a chequered history, calling into question the way in which soil and water conservation technologies have been studied in the past. This article draws on a case study from eastern Burkina Faso to explore an area usually ignored by soil and water conservation studies — the role of social institutions in guiding decisions regarding the use of technologies. It looks at soil and water conservation through the historical development of what the authors call the ‘cultural economy’, that is, a system of exchange in which a market economy has mixed with pre‐existing forms of exchange. The approach adopted by the authors identifies concepts on which the cultural economy is based and uses these ideas to analyse institutions that affect the choice of soil and water conservation technologies. The article shows how this approach leads to a reconceptualization of the ways in which soil and water conservation technologies are to be considered.     

Population Estimation Using Landsat Enhanced Thematic Mapper Imagery

An assessment of two groups of approaches for estimating urban population with remote-sensing information is presented in this article. These approaches, zonal and pixel-based models, are applied to Landsat Enhanced Thematic Mapper images of a portion of Columbus, Ohio , to generate population estimates. The zonal approach uses impervious surface fraction, spectral radiance, and land-use/land-cover classification to derive population estimates. The pixel-based approach uses impervious surface fraction and spectral radiance to estimate the population of residential areas. To assess robustness, these models were applied to Dayton, Ohio . A comparative study indicates that the models generated promising results in estimating regional population counts. However, zonal regression with spectral radiance produced large errors (76%) for census block groups, whereas other models gave significantly better estimation accuracy. Comparing the performance of the indicators, impervious surface fraction is competitive, and slightly but consistently better than land-use classification. In comparison with traditional zonal approaches, pixel-based models give somewhat better estimation accuracy.     

Development of a Methodological Framework for Handling Urban Archaeological Resources: Tarsus Historic City Centre,Turkey

In Turkey, most of the historic city centres have been continuously occupied since early ages, and ongoing research or ad hoc findings indicate urban archaeological resources beneath modern cities. According to the results of such research, archaeological and conservation sites are determined in terms of current legal frameworks. However, urban archaeological resources have not been included in the planning process because of inadequacy in spatial documentation, so archaeological deposits have been seen as problem areas in urban development. Thus, urban archaeological resources — not only subsoil resources, even monumental sites — could not be integrated into urban daily life, so most citizens are not aware of archaeological layers beneath their feet. The research project in Tarsus historic city centre, which is supported by the Scientific and Technological Research Council of Turkey (TUBITAK), primarily aims to develop a method to include urban archaeology — especially subsoil archaeological resources — into the urban conservation planning process of multilayered historic city centres in Turkey. In this way, planners would be informed, aware, and equipped about the urban archaeological potential at the earliest stages of the planning process. Consequently, urban archaeology, as an inter-/ multi-disciplinary field of research, is going to evolve as a crucial planning analysis in urban conservation including not only archaeological research, but also in evaluating settlement history and issues in urban development.     

Soil erosion and flooding on the eastern South Downs, southern England, 1976–2001

The South Downs in southern England have been farmed for 5000 years: the initial loess cover is now a thin, stony remnant as a result of erosion. During the 1980s, field monitoring of erosion events in an area of 36 km² showed that average rates of erosion are low (0.5–5.0 m³ ha⁻¹ yr⁻¹), but that occasional storms result in losses of over 200 m³ ha⁻¹ yr⁻¹ on individual fields. On soils that are only 15 cm thick, such rates pose a threat to future farming. Almost all recent erosion has been on fields of winter cereals, which are bare in the wet autumn period. Of greater significance in the short term are the effects of soil-laden runoff (or muddy floods) on urban areas. Flood damage to property has been a regular event since the conversion of this area to winter cereals in the 1970s. Soil conservation measures have been negligible and flood protection has consisted mainly of engineering works and limited land-use change at sites where property damage has occurred. Conversion to grass under the Set Aside, and an Environmentally Sensitive Area (ESA) scheme, could be an effective soil conservation and flood protection approach. In the longer term, increasing stoniness of soils, the economic incentives for arable farming in marginal areas, and the success of legal proceedings relating to flood damage, will determine the future of erosion on the South Downs. Current farming systems clearly are unsustainable and would become more so under future climates without substantial site-targeted land use change.     

Understanding cultural heritage in Turkey: institutional context and organisational Issues

This paper explores Turkey’s cultural heritage system from the perspective of the ‘Heritage Chain’, which sees the heritage sector as an interconnected series of relationships and activities including protection and conservation, archaeological activity, research and museum presentation. By reviewing quantitative data along each step of the chain, we construct a holistic perspective that shows interrelationships between activities and illustrates which parts of the system are underdeveloped. By demonstrating the effects of Turkey’s distinct combination of bureaucratic fragmentation and centralisation on professional practice among conservators, archaeologists and museums, we argue for increased attention to administrative issues within heritage studies.     

Relationship Between Green Areas and Urban Conservation in Historical Areas and Its Reflections: Case of Diyarbakir City,Turkey

City planning is essential for providing physical environment for better community life and for providing green areas, while conserving historical heritage is an important achievement in city planning, particularly for historical cities such as Diyarbakir city. The focus of this paper is to outline how increasing the ratio of green area in the city centre of Diyarbakir, Turkey, with a land-use betterment model exemplified sustainable urbanism. We observed an applied urban design project that included both opening up free space to the public and increasing the amount of available green area. The project addressed an area adjacent to the Diyarbakir city walls, which are important not only for their history but also as reflections of the urbanization process of Diyarbak?r from prehistoric time to the twenty-first century. We have noticed that changes in the design area provided understanding of the city planning by public and supplied more green areas for children and women. Thus, the city became more desirable and more sustainable.     

Identifying the Impacts of Land-Use Spatial Patterns on Street-Network Accessibility Using Geospatial Methods

While the land use-street network nexus is well acknowledged, evidence for the one-way impacts of land-use patterns on street accessibility is still inadequate. The measurements of land-use patterns and street accessibility lack systematic knowledge. Their empirical correlations also lack geographical variability, constraining site-specific land-use practices. Therefore, this study overcame the aforementioned limitations by examining the two-level spatial models to formulate accessibility-oriented land plans, using a well-developed Chinese city as an example. Firstly, two landscape metrics—Euclidean Nearest-Neighbor Distance (ENN) and Similarity Index (SIMI)—were used to quantify the intra- and inter-land-use configurations, respectively. Both city-level and local accessibility were measured using spatial design network analysis. Performing both ordinary least squares (OLS) and geographically weighted regression (GWR) models, results identified the statistically significant effects of inter-land-use patterns on two-level street accessibility. An exception was that land-use configurations within residential and industrial regions were irrelevant to street accessibility. We also found GWR was a better-fitting model than OLS when estimating locally-varied accessibility, suggesting hierarchical multiscale land-use planning. Overall, locally heterogeneous evidence in this study can substantialize land use-street network interactions and support the decision-making and implementation of place-specific accessibility-oriented land use.     

The role of forests in global climate change: whence we come and where we go

Neither the United Nations Framework Convention on Climate Change (UNFCCC) nor the Kyoto Protocol include a satisfying mechanism for reducing the substantial emissions from deforestation which are responsible for about a quarter of global greenhouse gas emissions. It is acknowledged that planting forests, for example through afforestation and reforestation in the Clean Development Mechanism, clearly provides an opportunity to sequester carbon in vegetation and soils. However, it takes decades to restore carbon stocks that have been lost as a result of land-use changes. Reducing the rate of deforestation is the only effective way to reduce carbon losses from forest ecosystems. As negotiations on a post-Kyoto agreement have already started the authors argue that a complete and fair post-Kyoto regime will have to expand existing regulations by creating a framework to encompass all land-use and forest-related changes in carbon stocks. Developing countries administer the majority of the world's environmental resources and provide a vital global public good by maintaining environmental assets. However, with increasing pressure on development and the use of resources, developing countries can hardly be expected to provide these services free. Therefore, they will have to be integrated into a more comprehensive incentive framework which also rewards forestry conservation, sustainable forest management and afforestation. The authors discuss how an incentive system for the protection of forests can be included in a future climate regime. Different design choices are considered and two recent approaches to reward developing countries that avoid further deforestation are compared: the 'compensated reduction of deforestation' approach and the Carbon Stock Approach.     

More than a Disease: The History of General Paralysis of the Insane in Turkey

This article explores the history of general paralysis of the insane (GPI) and its treatment in Turkey. GPI was considered as “a disease of civilization” at the end of the nineteenth century. From the early years of the twentieth century, Turkish psychiatrists discussed and interpreted the causes of GPI and followed the European diagnostic and treatment methods of the disease. Austrian psychiatrist Julius Wagner-Jauregg (1857–1940) introduced and developed “malaria fever therapy” for general paralysis in 1917. Malaria fever therapy spread to other countries and, during the 1920s, the treatment was also used in Turkey. This article not only aims to illuminate an unnoticed aspect of the history of psychiatry in Turkey but also uses GPI as a model to illustrate how psychiatry in Turkey was influenced by the developments in Europe.     

LGBTTs of Turkey between the east and the west – the city and the world through their eyes in the case of Izmir

The profession of city planning in Turkey does not consider groups such as LGBTTs (Lesbian, Gay, Bisexual, Transgender, Transvestite (Cross-dressing)). This study aimed to draw attention to the need for Turkish city planning to consider LGBTT people by presenting the results of a survey conducted in Izmir, one of the leading cities in Turkey. The study examines the reasons that LGBTTs, as ordinary individuals in society, become closeted in the urban sphere and how city planning can overcome this challenging problem of a Muslim country that is between the East and the West and is a European Union (EU) nominee. To examine this delicate issue that has not previously been considered in urban/rural planning studies in Turkey, the main discussion first elaborates the nationwide conception of and attitude towards LGBTTs and a wide range of social and economic variables to assess the quality of LGBTTs’ urban living. Then, based on results of the survey, this study attempts to formulate how an inclusive city can be planned for all groups, including LGBTTs. The scope of this study covers the legal and social status of LGBTTs in Turkey, the overall profile of LGBTT survey respondents, these respondents’ place in Izmir and the specific characteristics of an LGBTT-inclusive city. The unique contribution of this study is that it is the first to examine LGBTT individuals’ demands from the city on the basis of their different socioeconomic profiles.     

Approach to Trading Off Economic and Environmental Values in Industrial Land-Use Planning

Few contemporary issues have received as much sustained attention as the deterioration of the quality of our natural environment and, particularly, the need to manage the trade-off between economic growth and the quality of that environment. This paper discusses research currently under way to develop a land-use planning methodology that will help planners address the trade-offs between environmental quality and economic development. The methodology is used to evaluate the social, economic, and environmental impact of alternative land-use plans. The methodology consists of a regional analysis submodel and a site analysis submodel. The first component is based on an expanded input-output analysis incorporating land use, resource inputs, and waste-emission outputs. The second component is an empirical analysis based on the specific suitability and compatibility of proposed land-use development packages. The land-use planning model developed is applied to a case-study area centered on Charleston, South Carolina.     

Using Linear Integer Programming for Multi‐Site Land‐Use Allocation

Research in the area of spatial decision support (SDS) and resource allocation has recently generated increased attention for integrating optimization techniques with GIS. In this paper we address the use of spatial optimization techniques for solving multi‐site land‐use allocation (MLUA) problems, where MLUA refers to the optimal allocation of multiple sites of different land uses to an area. We solve an MLUA problem using four different integer programs (IP), of which three are linear integer programs. The IPs are formulated for a raster‐based GIS environment and are designed to minimize development costs and to maximize compactness of the allocated land use. The preference for either minimizing costs or maximizing compactness has been made operational by including a weighting factor. The IPs are evaluated on their speed and their efficacy for handling large databases. All four IPs yielded the optimal solution within a reasonable amount of time, for an area of 8 × 8 cells. The fastest model was successfully applied to a case study involving an area of 30 × 30 cells. The case study demonstrates the practical use of linear IPs for spatial decision support issues.     

Generating Alternative Land‐use Allocation for Mixed Use Areas: Multi‐Objective Optimization Approach

Current research is carried out with an intention to present an optimization approach for the urban land‐use allocation problem by generating Pareto optimum solutions considering two objectives—maximizing compatibility among adjacent space uses of a study area without compromising the area’s total land price and maximizing the price of plot of each individual owner. Considering the non‐linear characteristics of the objective functions, a multi‐objective evolutionary algorithm approach called Non‐Dominated Sorting Genetic Algorithm‐II (NSGA‐II) is applied to obtain Pareto optimal land‐use allocation subject to different set of constraints. The objective functions are tested over a case study area of Dhaka, Bangladesh. The resulting NSGA‐II model produces 24 Pareto optimal solutions of land‐use allocation, allowing tradeoff between maximizing compatibility and land price from one solution to other. This research also expresses the potential of the model to aid the policymakers and city planners of development authorities by providing alternative land‐use plans, and thereby predicting the consequences of any plan before practical application.
