Integrated urban evolutionary modeling

Cellular automata models have proved rather popular as frameworks for simulating the physical growth of cities. Yet their brief history has been marked by a lack of application to real policy contexts, notwithstanding their obvious relevance to topical problems such as urban sprawl. Traditional urban models which emphasize transportation and demography continue to prevail despite their limitations in simulating realistic urban dynamics. To make progress, it is necessary to link CA models to these more traditional forms, focusing on the explicit simulation of the socio-economic attributes of land use activities as well as spatial interaction. There are several ways of tackling this but all are based on integration using various forms of strong and loose coupling which enable generically different models to be connected. Such integration covers many different features of urban simulation from data and software integration to internet operation, from interposing demand with the supply of urban land to enabling growth, location, and distributive mechanisms within such models to be reconciled. Here we will focus on developin

Reapportionments of State Legislatures—Legal Requirements

The continuously rising attention to and practice of eco-city development in Sweden and China, as well as the countries’ active cooperation has motivated this study and the exploration of eco-city development in these two countries. In eco-city development, diverse environmental issues may well be beyond the planning sector’s capacity and need to be resolved elsewhere by other authorities and agencies in such areas as energy, water and traffic. This may in practice require the reframing of certain institutions to ensure that relevant sector authorities, scientific institutions and actors have responsibilities for integrative tasks and can cooperate effectively. The study aims to investigate how institutional conditions affect environmental integration in urban planning. The approach used is the exploration of how different institutional conditions promote and/or hinder environmental integration by the examination of four examples of eco-city development in Sweden and China. Based on theories of institutions, Environmental Policy Integration (EPI) and sustainable urban planning, an analytical framework is used to describe institutional conditions related to formal rulemaking, informal rules and administrative management and organizations. Formal rules provide framework and legitimacy for guiding and enforcing actors in the practice of realizing environmental integration in urban planning. Meanwhile, informal rules; i.e. wills, interests, understanding and knowledge, could considerably affect the design of formal rules and how they are to be implemented. Administrative management and organization serve to realize environmental integration following the formal rules, but the informal institutional conditions of e.g. officials’ interests, understanding, knowledge and experience, as well as political support, affect the organizations’ performance and abilities for implementation, which in turn also largely depends on the specific organizational settings. All three need to be combined to achieve environmental integration in sustainable urban planning, since each one has its own strengths and weaknesses and they gradually affect each other in practices.QC 20140908</p

Market institutions

This paper examines how market institutions can affect links between urban and rural areas with specific emphasis on goods market integration in the national context.Traditionally, development researchers and practitioners have focused either on rural market development or on urban market development without considering the interdependencies and synergies between the two. However, more than ever before, emerging local and global patterns such as the modern food value-chain led by supermarkets and food processors, rapid urbanization, changes in dietary composition, and enhanced information and communication technologies point to the need to pay close attention to the role of markets both in linking rural areas with intermediate cities and market towns and promotion of economic development and poverty reduction. This paper begins with a presentation of a conceptual framework of market integration and then identifies five major factors that increase the transfer costs that subsequently hinder market integration between rural and urban areas: information asymmetry, transaction costs, transport and communication costs, policy induced barriers, and social and noneconomic factors. Five specific cases in five developing countries are examined in this study to demonstrate the primary sources of transfer costs and the aspects of market institutions that are important to market integration and promotion of rural-urban linkages.Rural-urban linkages ,

Impact of Service Sector Loads on Renewable Resource Integration

Urban areas consist of a mix of households and services, such as offices, shops, schools, etc. Yet most urban energy models only consider household load profiles, omitting the service sector. Realistic assessment of the potential for renewable resource integration in cities requires models that include detailed demand and generation profiles. Detailed generation profiles are available for many resources. Detailed demand profiles, however, are currently only available for households and not for the service sector. This paper addresses this gap. The paper (1) proposes a novel approach to devise synthetic service sector demand profiles based on a combination of a large number of different data sources, and (2) uses these profiles to study the impact of the service sector on the potential for renewable resource integration in urban energy systems, using the Netherlands as a case study. The importance of the service sector is addressed in a broad range of solar and wind generation scenarios, and in specific time and weather conditions (in a single scenario). Results show that including the service sector leads to statistically significantly better estimations of the potential of renewable resource integration in urban areas. In specific time and weather conditions, including the service sector results in estimations that are up to 33% higher than if only households are considered. The results can be used by researchers to improve urban energy systems models, and by decision-makers and practitioners for grid planning, operation and management}.Comment: 32 pages, 7 figures, 4 table

Affordances of Historic Urban Landscapes: an Ecological Understanding of Human Interaction with the Past

Heritage has been defined differently in European contexts. Despite differences, a common challenge for historic urban landscape management is the integration of tangible and intangible heritage. Integration demands an active view of perception and human-landscape interaction where intangible values are linked to specific places and meanings are attached to particular cultural practices and socio-spatial organisation. Tangible and intangible values can be examined as part of a system of affordances (potentialities) a place, artefact or cultural practice has to offer. This paper discusses how an ‘affordance analysis’ may serve as a useful tool for the management of historic urban landscapes

Significance of Public Space in the Fragmented City: Designing Strategies for Urban Opportunities in Informal Settlements of Buenos Aires City

This article surveys the problem of urban marginalization by one of its more critical expressions in the contemporary city: the slums. The aim is to define an urban design strategy for the integration of those settlements as part of the city context, which enables to find solutions for the conflict improving these communities quality of life.slum, marginality, stigma, integration, public space, quality of life

Happiness in the Dual Society of Urban China: Hukou Identity, Horizontal Inequality and Heterogeneous

This paper studies the impact of income inequality on the subjective well-being of different social groups in urban China. We classify urban social groups according to their hukou status: rural migrants, gbornh urban residents, and gacquiredh urban residents who once changed their hukou identity from rural to urban. We focus on how the horizontal inequality-income disparity between migrants and urban residents-affects individual happiness. The main results are as follows. First, migrants suffer from unhappiness when the horizontal inequality increases, but urban residents show a much smaller aversion to the horizontal inequality. Second, migrants will not be happier if their relative incomes within their migrant group increase, while urban residents do become happier when their incomes increase within their groupfs income distribution. Third, gacquiredh urban residents have traits of both migrants and gbornh urban residents. They have an aversion to the horizontal inequality like migrants, and they also favor higher relative income among urban residents. Fourth, gbornh urban residents have lower happiness scores when they are old. People who are Communist Party members strongly dislike the horizontal inequality. Our findings suggest that migrants, gacquiredh urban residents, elderly people and Party members from gbornh urban residents are the potential proponents of social integration policies in urban China.Horizontal inequality, Happiness, Hukou identity, Migration, Social integration

The principles of integration in urban transport strategies

Integration as a principle in urban transport policy is frequently advocated but rarely defined. We suggest a range of types of integration, and highlight the problems in developing an effective integrated strategy, given the number of variables involved. We argue that integration should be designed to serve agreed objectives of transport policy, rather than being an objective in its own right. We then consider the principles for designing an effective integrated strategy. We define the concept of synergy, which is often advocated as a benefit of integration, and discuss whether it, and other aggregation benefits short of true synergy, are achievable. We then consider the alternative approach of using integration to overcome barriers, an approach which is likely to be in conflict with pursuit of synergy, but more likely to lead to readily implemented strategies. We then review a number of examples where these principles have been applied, and investigate them to assess whether synergy has been demonstrated. Generally we find little evidence of synergy in outcome indicators. We conclude with some more general guidance on approaches to integration

Urban management revolution: intelligent management systems for ubiquitous cities

A successful urban management support system requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated transparent and open decision making mechanism. The paper emphasises the importance of integrated urban management to better tackle the climate change, and to achieve sustainable urban development and sound urban growth management. This paper introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for ubiquitous cities. The paper discusses the essential role of online collaborative decision making in urban and infrastructure planning, development and management, and advocates transparent, fully democratic and participatory mechanisms for an effective urban management system that is particularly suitable for ubiquitous cities. This paper also sheds light on some of the unclear processes of urban management of ubiquitous cities and online collaborative decision making, and reveals the key benefits of integrated and participatory mechanisms in successfully constructing sustainable ubiquitous cities

Insights on the spatial configuration of collective spaces within forming dynamics: the relation between infrastructure and urban transformation in Plaça de les Glòries Catalanes

The research seeks to produce insights on the spatial configuration of collective spaces where large scale infrastructure propels urban transformation. Focusing on the meaning, character and programmatic qualities of urban spaces in transformation as outcomes of fluctuating processes, it deals with complex spatial forming dynamics of urban streetscapes: the non-traditional conjugations of spaces, boundaries and territories. These spaces foster unexpected notions of proximity, territoriality, permeability and critical boundaries, investigated by means of specific parameters manifesting and interacting in time. This can help upgrade the design of architecture and urban projects to innovative techno-cultural practices and improve their integration in the urban fabric; urgent matter within the hyper-complex conditions of contemporary urban realities. The case of Plaça de les Glòries Catalanes in Barcelona, where a car-oriented open-space based on a variety of spatial manifestations turns into a formalized urban centrality, is used to unveil the complex convergence of streetscapes and urban infrastructures in contemporary urban transformations
