Evaluating Land Surface Changes of Makassar City Using DInSAR and Landsat Thematic Mapper Images

Urban growth has been a major issue in environmental monitoring and changes occurred on land surfaces have been monitored by applying remote sensing as well as ground measurement. Most major cities in the world have experienced land subsidence phenomena on some parts of them due to the load of development and modernization. Excessive extraction of groundwater for the needs of industry has led to the condition where the water table drops, and this can possibly trigger subsidence, as observed in Indonesian cities. In this study the authors have shown that the application of DInSAR （differential interferometric synthetic aperture radar） technique using Japanese Earth Resources Satellite-I Synthetic Aperture Radar JERS-I SAR data can reveal subsidence conditions in the studied Makassar city area. Landsat TM （thematic mapper） images were used to evaluate the change of land cover during the observation period of 1994-1999. Makassar is fiat, covered mainly by alluvium deposit that is vulnerable to the load of constructions, and volcanic formations which is porous and will easily be degraded by groundwater extraction. It is found that mostly the subsidence has occurred in the western part of the city, including the industrial district, reclamation area, trading center area and the seaport area. The ground survey has indicated that high human activity exists in every point of subsidence. It is likely that various human activities such as ground water pumping and construction work should have affected the local subsidence phenomena in Makassar, as in the case of other large-scale cities in Indonesia.     

Analysis of Urban Morphology in Core Towns＇ Neighborhoods of Mexico： Santa Barbara＇s Neighborhood as a Case Study

Cities＇ urban morphology is the result of historic, cultural, political and social processes. The historical cores in Mexican cities have high cultural diversity, which also intermingle pre-Hispanic cultures with colonial forms, as well with modernity and post-modernity irruption. The case study is Santa Barbara＇s neighborhood in Toluca City, which was founded in 1524, and the case study was the first neighborhood in Toluca＇s historical core. At present time, this neighborhood is considered as one of the most dangerous places in the city＇s historical core, therefore, it has been abandoned. This paper will display the changes in urban morphology of the neighborhood through the years from 1877 to 2010. For site evaluation, the methodologies of Ashihara （1982） and Lynch＇s （1961） were used in order to analyze positive and negative spaces, as well as main street visual features, street and avenue directions, street circulation and street circulation path configuration. The results show that the focal nodes are a key factor for economic and social reactivation, with which, through urban activation of vacant lots and the traditional use of the streets as public space, is possible to generate centripetal development to restructure the neighborhood.     

Historicity： Preservation or Revitalization Planning Tools？

The historic centres revitalization addresses the challenges related to the preservation of fundamental heritage values. At a time, when everyone looks with concern to our cities＇ future, it is important to reflect on the received heritage, seeking the most appropriate answers to the planning of the historic centres. These fabrics are reference places in the urban space, due to their role of memorial testimony and of generators of cultural and economic dynamics. However, often times, inherited urban fabrics are affected by the limitations of the heritage policies which, for being too general and based on theoretical and abstract frameworks, have difficulty incorporating the characteristics of each area and neglect the formulation of specific criteria and intervention methods. The purpose of this paper is to provide a comparative reading of the levels of urban renewal allowed by the planning tools. This study chooses two historic centers in Portugal： Oporto and Guimarfies historic centres （World Heritage Sites since 1996 and 2001, respectively, and were the last to get this classification in Portugal）. This reflection is a contribution to peer trends and raise the discussion on the role that the different heritage policies have to the revitalization of the historic centres.

On-Demand Post-Disaster Emergency Shelters

In post-disaster emergency shelter aid, various relief agencies and other actors with different backgrounds need to cooperate in a tremendously short amount of time and under very different circumstances. In this article, we describe a research project that develops and tests a new approach in which the demands for shelters in a specific situation are methodically connected with available, innovative and sustainable shelter solutions, a DSS （decision support system）. The DSS is a digital tool that translates the gathered evidence on needs, solutions and location including long-term effects of shelter provision into advice for the provision of sustainable, integral broader shelter solutions and designs. The outcome is a set of characteristics for a DSS for the provision of on-demand emergency shelters. A DSS that meets these characteristics leads to the provision of sustainable shelters that meet the needs of the users and, therefore, have higher performance in long term.     

Sustainability of Touristic Potential of the Old Van City and Castle of Van in Terms of Cultural,Historical and Natural Values

Tourism has become the world＇s fastest growing sector due to acceleration of technology and information flow in the globalized world of today, development of the modem mass transport system and increase in people＇s disposable income. Upon tourism＇s being considered as a serious development strategy in the developments of the countries, all the countries of the world have begun to accelerate their investments in this area through utilizing the natural and cultural assets of their countries （heritage） with a view to provide revenue to their economy as well as creation of jobs. This situation, which has emerged as a result of the globalization of supply and demand in tourism, has created certain problems in terms of environmental balance and the living conditions of local people as a result of poor management of the utilization of natural and cultural resources. The objective of this paper is to examine the concepts and principles germane to sustainable tourism which has significant contribution to the development of the countries, made at the macro level both in the world and in Turkey. The aim of this paper, at the micro level, is to create awareness incident to the tourism resources of the Van Region and the Old Van province and ensure the utilization of these resources through protection thereof. At the end of the study, the importance of the protection of heritage resources as well as fair use thereof in terms of increasing the competitiveness of Turkey on a global scale in tourism is addressed in the light of the overall evaluations.     

BIPV in the Refurbishment of Minor Historical Centres： The Project of Integrability between Standard and Customized Technology

The proposed research is aimed to define some BIPV （building integrated photovoltaics） paradigms for the refurbishment of historical contexts, by defining strategic criteria related to linguistic-architectural and technological-constructive aspects of solar systems （including case-studies in specific application contexts）. This research could, once perfected and shared, be used within operative tools （guidelines, case studies, etc.） really applicable to common scale, e.g., in today＇s post-earthquake reconstruction in L＇Aquila, for defining possible solar implementation possibilities in sensitive areas according to an innovative and sustainable method of intervention.     

Cold In-Place Recycling as a Sustainable Pavement Practice

Pavement rehabilitation and reconstruction methods with CIR （cold in-place recycling） are alternatives that can effectively reduce the high stresses and waste produced by conventional pavement strategies. An attempt was made to predict the performance, particularly low-temperature cracking resistance characteristics of CIR mixtures. These were prepared with the mix design procedure developed at the URI （University of Rhode Island） for the FHWA （Federal Highway Administration） to reduce wide variations in the application of CIR mixtures production. This standard was applied to RAP （reclaimed asphalt pavement） to produce CIR mixtures with CSS-Ih asphalt emulsion as the additive. By adjusting the number of gyrations of the SGC （Superpave gyratory compactor） for compaction, the field density of 130 pcf was represented accurately. To secure a base line, HMA （hot mix asphalt） samples were produced according to the Superpave volumetric mix design procedure. The specimens were tested using the IDT （indirect tensile） tester according to the procedure of AASHTO T 322 procedure at temperatures of-20, -10 and 0 ℃ （-4, 14, and 32°F, respectively）. The obtained results for the creep compliance and tensile strength were used as input data for the MEPDG （mechanistic empirical pavement design guide）. The analysis results indicated that no thermal or low-temperature cracking is expected over the entire analysis period of 20 years for both HMA and CIR mixtures. Thus, it appears that CIR is a sustainable rehabilitation technique which is also suitable for colder climates, and it is recommended to conduct further investigation of load-related distresses such as rutting and fatigue cracking.     

Measuring Thermal Mass of Sustainable Concrete Mixes

Thermal mass is currently evaluated with ＂admittance＂ which is the ability of the element to exchange heat with the environment and is based on specific heat capacity, thermal conductivity and density. The aim of this study is to evaluate the effect of thermal properties namely, density, specific heat capacity and thermal conductivity on thermal mass. The objective of the study is to carry out laboratory experiments by measuring such thermal properties of concrete mixes with various percentages of GGBS （ground granulated blast furnace slag）, PFA （pulverized fuel ash）, and SF （silica fume） and RCA （recycled coarse aggregates）. The results obtained from these tests would contribute to the evaluation of how such thermal properties influence the thermal admittance and hence the thermal mass performance of sustainable concrete elements in a building system.     

Strengthening of the Territorial Position of Valladolid through Planning Strategies： Networks,Patterns and Centralities

The urban condition of the European territory requires new approaches to explain the current development of cities and to propose new planning tools. The aim of this paper is to demonstrate that we can support an innovative perspective based on intermediate geographical scales, more useful for outlining the specific features of territory. While we analyze the territory, we should overcome the strictly local scale of the administrative boundaries and create new relationship between contemporary urban concepts （metropolization of territory and metapolis） and the regional ecological patterns. In the case of Valladolid （E） urban/metropolitan area, we focus on both causes and process of city growth. We have understood that it could be inefficient for planning forgetting the real spatial configuration （the city is located in an intersection between two territorial corridors） and misunderstanding the territorial role of the city at different scales （the double centrality in the emerging urban area and in the region）. The significance of this case is to reveal the inter-scalar condition of places as generators of constraints in the contemporary urban fabric and, at the same time, to show the quality and the potential of places in the future urban realm.     

Images of the Future from the Past： The Metabolists and the Utopian Planning of the 1960s

During the 1960s, many changes reshaped the economy, the society and the arts. The Cold War, the Space Race, the construction of a new middle class in most western societies led by the postwar economic prosperity with unprecedented urban growth followed by severe environmental problems fostered the design of spectacular urban utopian cities and mega-architectures. In those years, Japan was the source of highly influential bold and visionary urban and architectural ideas which relied on advanced technology. These ideas were conceived on the thought that cities could be seen as gigantic but impermanent entities able to transform itself according to an organic process of adaptation of its elementary components. This paper briefly revisits and critically discusses the legacy of the iconic mega-strnctural projects of Japanese Metabolist Movement and other visionary architects and planners of the 1960s, such as Paolo Soleri, Buckminster Fuller, Archigram. It attempts to enlighten the continuity with contemporary innovative and experimental urban models and ideas for the society and the city of the future, such as the Smart Cities, Eco-Cities, Green Urbanism, whose design is led by concerns related to climate change, the necessity of energy efficiency, the improvement of urban landscape and the valorization of depleted natural resources.     

Resilient Development of Urban Waterfront in Fast-Changing Cities--A Case Study of Wuhan,China

Urban waterfronts, where the land of city meets a body of water, are unique and finite resources representing the best opportunities for community enhancement and enrichment. On the other hand, waterfronts are also high-risk areas, where the water-related disasters could seriously affect the long-term sustainability of urban environment. This paper focuses on the relationship of the cities with their waterfronts. It presents a case study of Wuhan--a Chinese metropolis, where waterfronts play an important role in its urban planning policy. It attempts to investigate the mechanism of waterfront transformation, and to find out which strategies to adapt and what resilience means in terms of urban waterfronts in a rapidly transforming city. This article examines some representative urban projects on the waterfront and summarizes spatial models applied on the waterfront with distinct policies. Finally, it demonstrates that an urban waterfront is an ＂osmotic interface＂ which should be more correctly envisaged as a network of places, functions, additions and hinges between the city and its water environment. It clarifies that waterfront areas represent a multidisciplinary and multitasking issue in perspective of urban resilient development.     

Gross Pollutants Study in Urban Areas under Tropical Climates

Gross pollutants are the primary targeted pollutants in urban catchment management for urban water quality improvement as well as mitigation of flood. Apart from aesthetically unattractive because of its visibility, gross pollutants also contributes to degradation of river water quality and loss of aquatic habitat as it carries harmful pollutants such as oxygen demanding material, hydrocarbons and heavy metals. This study analyzed trend of gross pollutant generated from two urban residential areas located in Selangor, Malaysia. The median value of gross pollutant load obtained fi＇om the Amanah Apartment and Bandar Botanic are 347.41 kg/ha/year and 32.46 kg/ha/year, respectively. Relationship between gross pollutant wet load with rainfall depths was derived using regression equation. A significant trend of increasing gross pollutant wet load into drainage system with increasing rainfall depth was observed. The behavior of pollutant load is related to the one observed in Australia.     

Narratives of Spatial Division： The Role of Social Memory in Shaping Urban Space in Belfast

The paper examines the role of shared spaces in divided cities in promoting future sustainable communities and spaces described as inclusive to all. It addresses the current challenges that prevent such inclusiveness and suggests future trends of its development to be of benefit to the wider city community. It explains how spaces in divided cities are carved up into perceived ownerships and territorialized areas, which increases tension on the shared space between territories; the control of which can often lead to inter-community disputes. The paper reports that common shared space in-between conflicting communities takes on increased importance since the nature of the conflict places emphasis on communities＇ confidence, politically and socially, while also highlighting the necessity for confidence in inclusion and feeling secure in the public domain. In order to achieve sustainable environments, strategies to promote shared spaces require further focus on the significance of everyday dynamics as essential aspects for future integration and conflict resolution.     

Joining Paths and Dividing Paths： Juiz de Fora, Brazil

The aim of this paper is to present the urban history of Juiz de Fora, a city with some 500,000 inhabitants in southeastern Brazil, and discuss how strategic decisions about the planning and construction of roads and highways can determine ways of life in a city. While paths may integrate landholdings and territories, they may also segregate communities and environments, causing deep rifts in the fabric of urban and land areas. The growth of Juiz de Fora is particularly marked by the construction of paths. This article reviews the local urban history from the establishment of paths in the city, to an analysis of the major impact and benefits they have had, notably on the local economy and demographics, as well as on the conservation of the local environment： Issues that are frequently relegated to a secondary role in the cost-benefit analysis of the city＇s planning decisions. After analysis of the case study, the authors concluded that citizens should be included on the agenda of the city, from spectators to actors of daily urban life.     

Improving Open Spaces for a Sustainable City

The feasibility of city living with nature as a way to restore the balance between human uses and natural processes is the focus of this paper about the city of Maringa in Southern Brazil. This urban form, a planned new town founded in 1947 upon a previous, comprehensive British land-development scheme, originally offered a friendly interaction between urban settlement and nature. Hence, this paper outlines how open spaces can be enhanced as an ecological structure, bringing parks, squares, gardens and urban farming into a productive system, both for nature＇s and for people＇s sakes. Following a morphological study, the proposed ecological structure will maintain ecological processes within the urban grid and help to preserve historical and social values, by linking a wide variety of natural and restored ecosystems and landscape features. The adoption of this kind of ecological planning will certainly result in an increase of the urban landscape quality, changing actual planning paradigm and preventing the city from environmental quality decrease.     

Improving Conviviality in Public Places： The Case of Naples, Italy

Under the umbrella concept of conviviality in public spaces, a research project on the rehabilitation of urban areas for commercial and retail uses---as engine of a complex process of production of places for social and cultural mixit6--has been defined. The aim of this research has been to produce useful tools for coping with the abandonment of public spaces in former commercial urban areas, without generating anonymous and globalized commercial districts. Through involving local stakeholders in a participatory process, the first phase of the research here presented needs to demonstrate the possible effectiveness of a pilot action plan in dealing with both isolation and gentrification processes of historical centres. The main hypothesis is that traditional retailers should be considered an essential element to ensure effective public use of urban public spaces. The research methodology is based on a qualitative approach. Focussing on the process of impoverishment within local commercial districts, the research group started working with local stakeholders in order to identify priorities and criticisms for enhancing a regeneration process. The case study to be carried out in Naples is the historical market place of Piazza Mercato in the Citth Bassa of Naples （Italy）.     

Tourism as an Industry in Heritage Site-A Case Study on World Heritage Site of Fujian Tulou

Cultural heritage is seen as a cultural capital. The heritage tourism increases the local employment and income, however, brings some problems at the same time, changing the traditional living way and industrial structure. The sustainability of economic development by tourism is also questioned. Fujian Tulou is a world heritage site in China, inscribed in 2008. The nomination has brought great changes to the sites, especially the flourishing tourism industries by the local communities as well as the tourism companies. The latter also take part in the management of the heritage site and get most of the income. The data in economic areas is analyzed in this study and explains the cultural tourism as a positive drive for the local economy, which contributes little to the life of locals. With the analysis of the changes and benefits from the tourism, we have found that tourism, as a dominant industry, might be a potential negative element for heritage conservation. According to the different situations of sites in Fujian Tulou, a proper planning of management is in need to integrate the tourism, conservation and development.     

Putting Places First in Competitive Urban Transformation European Urban Creativity Perspectives and the City of Sarajevo

The inter-urban competition seems to be of paramount importance for city-development today. The extensive reliance of competitiveness-oriented urban governance agendas on the knowledge-based, ＂new＂ economy, introduced the notion of ＂creativity＂ into discussion on the future of urban development. Though still on the margins of serious urban theory, the discourse on ＂creative cities＂ that emerged in the early 2000s, has already had massive influence on the ways in which cities are managed and transformed in Europe. After examination of how the competitiveness-oriented strategies based on creativity and related to the qualities of place increase cultural and social sustainability of urban transformation and development, this paper briefly rethinks the current urban development policy of the city of Sarajevo in relation to the notion of ＂place＂, by leaning on the contemporary European urban development paradigm. The conclusion points out that the sustainable increase of urban competitiveness in Sarajevo should be pursued by the development projects of urban transformation promoting creative knowledge sector, based on the inclusive cultural urban narratives related to places, thus assuring simultaneous growth of creative knowledge industries and preservation of diverse social geography.     

Design and Management of Building＇s Resources

The developed modem control systems and buildings management resource systems would be effective if they are based on previously established optimal conditions during the building design. This is one of the key issues for a responsible architecture. The focus of this paper is on sustainable design methods and techniques for saving resources and their management throughout the building lifecycle. The main subject of the present article is the characteristics of these methods and their fundamental role in sustainable resource management during the building operation. The results which are based on conducted case studies of European and international practice in the construction of sustainable buildings are implemented here. Key features of a comprehensive approach for design and construction are outlined via comparative analysis, as well as various systems for the evaluation of sustainability for already constructed buildings. The mostly used criteria and indicators for sustainability are systematized, including those related to resource consumption. By analyzing a specific example, the role of sustainable design methods is justified as an important prerequisite for effective management of building resources in the process building maintenance. According to the conducted studies, during the longest life cycle period of a building, by implementation of control systems and resource management of building, the costs are successfully optimized. Specific directions that prove the effectiveness of such systems are systematized in the paper. Innovative approaches, complex methods and measures for design and management of buildings resources are presented as results of this study.
