Peri-urban livelihood dynamics: a case study from Eastern India

Abstract: An important development of the urban settlements during the last few decades has been the rapid expansion of the population and the built-up area into the administratively different suburbs and areas surrounding the large towns and cities. These areas suffer from the negative consequences of unplanned urban growth, associated land use changes, rapid social change and degradation of natural resources. Burdwan city is situated along the greater Kolkata metropolitan area and Asansol industrial area corridor. As a result, this city has experienced problems such as socio-spatial segregation, socio-economic and cultural gaps as well as uncontrolled land markets and the spread of informal development.
The present study examines the empirical findings of socio-economic transformation as a part of peripheral urbanization. For a better analysis, the livelihood asset index (LAI) and household quality of life index (HQLI) were determined. Livelihood asset index is analysed by considering four capitals i.e. physical, human, financial and social with 12 index components. Villages located nearby city have high index whereas far distance villages have a low index. Finally, it is concluded that as livelihood asset increases, the quality of life also increases in the peri-urban villages of Burdwan area.

A Belief-Desire-Intention Agent-based procedure for urban land growth simulation. A case study of Tehran Metropolitan Region, Iran

Abstract: Urbanization, growth of urban areas, is a process that has been growing rapidly during the last two decades. This phenomenon affects aerobiological, economical, industrial, ecological processes, social control, and the family. Hence, the prediction of the urban area extent has an important role in the future decision of the municipality. Multi-Agent System (MAS) is a proper tool for simulation and modeling process, which has been used for solving different types of spatial and non-spatial problems. In this article, we use MAS for urban simulation in the rural area around Tehran, which is the most populated and the fastest-growing city of Iran. In this paper, the behavior of three groups of agents: environmentalist, industrialist, and resident are simulated. These three groups are the dominant and influential population in the formation of urban texture. In this research, the behavior of these three groups of agents is specified, according to a series of map layers, such as slope, aspect, soil type, distance of urban areas, roads, and so on. The Belief-Desire-Intention (BDI) architecture of agents is used for the simulation, which is defined based on some variables, functions, and coefficients. The simulation is carried out based on two different interaction scenarios: Rational and Nash-Equilibria. The future urban area is predicted by a combination of MAS and spatial urban area. To evaluate the proposed model, the comparison of the predicted area is made at different times and scenarios. The results of implementation in different scenarios show that the residents of the study area follow the Nash-Equilibria interaction with Kappa Coefficient accuracy of 0.8104.

Using GIS methods to analyze spatial characteristics of urban transportation system in Craiova city

Abstract: In a world of technology, where the increasing urbanization tries to cope between sprawl and the need to actively manage a sustainable land and resources use, transportation remains among the main challenges for physically active cities like Craiova. The city is the major growth pole located in South-West Oltenia, which connects most of the settlements in the region (both rural or urban) economically and socially. Thus, the transportation system represents the key element in the relation between time and place in this metropolitan area in a continuous development process. While the city expands, the transportation network, inherited from the past, suffers a slower transformation, despite the increasing demand for mobility coming from both passengers and freights. The spatial analysis of new residential areas emerged in the continuous process of urban expansion indicate an additional pressure on the existing road infrastructure and which intensifies especially during peak hours on the access routes to the city and city center. Starting from the analysis of the spatial structure and distribution of the pre-existent rural structure, the present study tries to emphasize the need for an innovative and integrated infrastructure that should connect at its best space, services and people in terms of speed, capacity and cost efficiency. First, using the GIS mapping methods, the authors present the spatial distribution of the transport infrastructure that is correlated with population density and land use, also analyzing the areas with high density of jobs and elements of the urban landscape that may generate attractivity. A special attention is paid to the urban form – street pattern relation, exemplified by case studies in problematic intersections of Craiova city. All these factors are important in order to establish the present capacity of the urban transportation system during peak hours, and what are the main deficiency of the transport system: traffic jams, insufficient parking places, need of new connections in public transportation. The results of the research may be used to improve passenger transport inside the city of Craiova and may also suggest some solutions that mitigate for the introduction of new concepts like car sharing, electric public transportation, hybrid vehicles or new alterna-tives for peoples’ movement.

Time- spaces in Hungary

Abstract: This paper firstly gives a general outline about the features of various spaces. Time spaces and cost spaces have non-metric characteristics, moreover, time spaces and cost spaces are not continuous. Therefore, topographic maps are not always an appropriate basis for cognitive information processing, the everyday behaviour and the study of spatial relationships. The paper demonstrates the differences between geographical space and time-spaces at two different scales, such as the road network time-space of Hungary and a district of the capital city Budapest. With the first example the rapidly changing Hungarian time-space during the last two decades can be vividly demonstrated, thanks to new motorway construction. The second example compares different types of space, as for example the difference between the time- space of a pedestrian and a vehicle.
