Global urban expansion has created incentives to convert green spaces to urban/built-up area. Therefore, understanding the distribution and dynamics of the land-cover changes in cities is essential for better understanding of the cities’ fundamental characteristics and processes, and of the impact of changing land-cover on potential carbon storage. We present a grid square approach using multi-...

This paper explores the relevance of Bourdieu's 1980 spatial theorisation in Le Sens Pratique (The Logic of Practice 1990, Polity Press, Cambridge) for understanding intercity relations in contemporary globalisationöspecifically, interdependencies between Castells's `space of flows' and `places' in advanced business services. Bourdieu's relational concepts are reviewed with reference to evidenc...

The paper contributes to the conceptualization of cities in the world by first outlining the conceptual and empirical challenges of theorizing the urban/global nexus in both relational and territorial terms. It argues that the mo...

Dynamic social media content, such as Twitter messages, can be used to examine individuals' beliefs and perceptions. By analyzing Twitter messages, this study examines how Twitter users exchanged and recognized toponyms (city names) for different cities in the United States. The frequency and variety of city names found in their online conversations were used to identify the unique spatiotempor...

Similar to physical cities, which emerged over many years in the physical world, we envision many kinds of large-scale “information cities” (iCities) to emerge over the Internet in the coming years. Some of these iCities will mimic small and large “physical” cities. They will provide local and global information and various valueadded services to inhabitants. Just like physical cities, these in...

space, according to Brian IL. Berry's famous expression (1964) «cities as Systems within a System of cities». Thus, the focus on the dynamic study of the general characteristics of the object «town» in an urban system of dissymetric interdependencies at a regional, national or global scale (Pumain 1997) was followed by the study of cities as physiognomic and socio-economic entities.This is diff...

lose to 4 billion people live in cities. As the driver of environmental challenges, accounting for nearly 70% of the world’s carbon emissions, and as sites of critical social disparities, with 863 million dwellers now living in slums, urban settlements are at the heart of global change. This momentum is unlikely to disappear, as approximately 70 million more people will move to cities by the en...

Using perception of quality of life survey by Eurostat we construct the City Ecosystem Index (CEI) – a systemic indicator that measures subjective well-being in European cities. The purpose of the index is to inform public, policy-makers and entrepreneurs by providing a holistic view on subjective well-being across European cities. Once contrasted with the Global and Regional Systems of Entrepr...

Cities are rapidly growing. There is an assumption that 90% of global population growth will be in cities between now and 2030. Therefore, infrastructures and the environment have to be adapted to the changing demands. Moreover, new urban development strategies have to be elaborated. In 2007, the first international Visualization Summit of more than 100 international researchers and practitione...

In the wake of 21st century, humanity witnessed a phenomenal raise of urban agglomerations as powerhouses for innovation and socioeconomic growth. Driving much of national (and in few instances even global) economy, such a gargantuan raise of cities is also accompanied by subsequent increase in energy, resource consumption and waste generation. Much of anthropogenic transformation of Earth’s en...
