Mobility of Urban and Rural Labour and Urbanization

By defining urbanization, the author approached the mobilityof labour between countryside and cities and pointed out that thismobility was determined by the capacity and repulsive force of agri-culture as well as urban attraction and absorbency. While analysingthe relations between the four determinative factors, the author ex-pounded different channels of labour transfer under conditions ofbalance and imbalance.

Topos and Identity

I have before me now a booklet entitled A New Wave of Japanese Architecture. It served as the catalogue of a 1978 exhibition of 11 Japanese architects—the youngest was then in his thirties and the oldest in his early fifties—that was held at the Institute for Architecture and Urban Studies then headed by Peter Eisenman. Kenneth Frampton's introduction, an account of how the Japanese architectural scene in the late 1970s looked from the outside, is rather accurate and interesting.     

Figurations of spatiality and temporality in participatory design and after – networks,meshworks and patchworking

In recent years, many have combined actor–network theory (and after) and collective design. In this emerging field that we call participatory design and after, many have proposed and appropriated figurations such as networks, fluid, fire, thing and meshwork. In this paper, we argue that figurations do not only contribute to knowing the world, they also intervene in the becoming of worlds. This recognition of the performative character of figuration suggests that knowledge-making and world-making are inseparable, and makes it very important to be careful what figurations we imagine, articulate and use. In order to continue the work done in ANT and collective design that focuses on uncertainties, boundary-making, complexities and time, we propose the figuration of patchworking. What we particularly find generative with the figuration of patchworking is that it figures design as entanglements in multiple temporalities. Through the figuration of patchworking, we offer an approach that allows for understanding and working with multiple and overlapping collectives. This means to refigure how and where to draw the boundaries of co-designing in technological societies.     

Bogotá and Medellín: Architecture and Politics

In the last 15 years, Bogotá and Medellín, Colombia's two largest cities, have undergone urban renaissances. These are a direct result of a political will to tackle the social, economic and physical segregation caused by the large-scale urban migrations of the 1970s and 1980s, which resulted in informal developments that were often isolated from central urban areas with no infrastructure. Lorenzo Castro and Alejandro Echeverri describe the shared experiences and distinct approaches of each city. Copyright © 2011 John Wiley & Sons, Ltd.

Urban hydrology and water management – present and future challenges

Urban hydrology is an applied science that will have an increasing role to play in the sustainability of human societies. Facing present growth of urban population, it is increasingly difficult to find and utilize new sources of water necessary to satisfy growing water demand. For the poor, the residents of peri-urban and squatter areas, an ultimate poverty, the poverty of lacking clean water, is a result. To remove this kind of poverty should be a first priority target for all people and, especially, for people dealing with water management in urban areas. Growth of urban areas brings significant changes in physical properties of land surface increasing integrated vulnerability of inhabitants, agricultural land and rural ecological life supporting systems. Performance of technical solutions depends on climate as well as on social, economical and cultural conditions. Findings from urban hydrological studies based on collection of urban hydrological data, calculations and modeling constitute a necessary fundamental for meaningful water management not only in urban areas but also in entire river basins. Future challenges in urban water management include development of new technical solutions as well as logistic and organizational methods in order to turn present problems into future opportunities. The following current and emerging challenges are discussed in the paper: delivery of drinking water supply for growing cities, water for sanitation versus sanitation without water, recycling of wastewater nutrients, wastewater irrigation, urban agriculture, water to feed depleted aquifers, thoughts about possible future new system solutions, social equity and transfer of knowledge and new technology.     

Telecommunications and transportation infrastructure: inter- and intra-sectoral borders — perspectives from Australia and the US

A growing body of literature suggests that the segregation of infrastructure and urban/regional planning is at the root of contemporary problems facing many of the world's metropolitan areas. More recently, the introduction of new telecommunication infrastructure highlights the invisible borders that exist within critical infrastructure that provide advantages to some areas such as transportation and disadvantages to others. This paper attempts to understand the nature of inter-sectoral and intra-sectoral borders across infrastructure in Australia and the US. It examines the sometimes contradicting market-led vs. government-led models adopted in the two countries to deliver broadband communications and transportation. The findings identify similarities and differences between the two countries, and reiterate that in order to achieve social equity, and enhance the provision of infrastructure to non-pro?table areas, government intervention is required. The paper concludes with a call for performance-based policies that go beyond traditional borders in an effort to better address the contemporary wicked planning problems.

Retrospect and Prospect of the Protection and Reconstruction of Old Beijing

Beijing is a famous,cultural and ancient capital inour country and one of the first group of famous,histori-cal and cultural cities proclaimed by the State Council.The Imperial Palace,the Great Wall and the Ape—manCave are listed as the” world cultural heritage”,whichhas further confirmed Beijing’s historical position in theworld.It has always been an important task in the field ofBeijing’s overall planning to protect this historical citywell while carrying out its modernization.At present,itbecome more important to do so for Beijing when the re-form and opennng policy is accelerated,the socialist mar-ket economy is being set up and the development of thecity is speeded up.To protect and reform the old Beijing,a great dealof valuable exploration has been put into practice overthe past more than 40 years.The work is now heing putinto a more scientific course.A few points of view are asfollows:

Assessment and Impact Factor Analysis on Stormwater Regulation and Storage Capacity of Urban Green Space in China and Abroad

Stormwater resources are not effectively utilized in many Chinese cities, which not only wastes water resources but has also brought about serious urban flooding problems. Urban green space, as a resilient approach of stormwater regulation and storage, has been widely applied in urban flooding control and sponge city construction. Through a review on relevant literature in the past two decades, this paper systematically compares the methods commonly used in the assessment on stormwater regulatio...
