Genshanmen Urban Centre and Transport Interchange

This project is the result of a collaborative design process involving QUT School of Design, and AREN Consulting and ZIAD (Zheijiang Provincial Institute of Architectural Design and Research). This project is the submission prepared by the above partnership for an invited international design competition, promoted by Hangzhou City, China. ---------- This major urban design and architecture project is for a large transport oriented development on the new Hangzhou Subway system. The development, covering several city blocks, includes the provision of residential, retail, education, commercial, and transport infrastructure; integrated with rail, bus and ferry systems. ---------- The design strategies are based on the development or artificial land forms; the cutting of new canals, raising of the ground plane, and metaphoric reference to the Yellow Mountains (explored in the detail of the central ‘ridge’ of built form). Further to this, the project explores the integration of sustainable technologies and philosophies with large scale building projects in a subtropical context.

Public engagement in major projects : the Hong Kong experience

Public engagement is an essential process for major municipal infrastructure and construction projects as it serves to identify the interests and concerns of citizens before the planning and design are finalised and thus ensures the schemes are beneficial to all sectors of the community. However, the success of public engagement depends on a number of factors, not least the suitability of the engagement methods used, representativeness and activeness of participants, time pressure, financial constraint and so on. In Hong Kong, the community has experienced discontent with several major projects recently, suggesting the need to examine the effectiveness of its current public engagement mechanism. This paper reports the results of a series of interviews with a variety of stakeholders – indicating the need for a carefully considered public engagement plan to be established at the beginning to drive the process and more experienced people to lead and facilitate the engagement process.

Temporal trend of pesticide concentrations in the Chikugo River (Japan) with changes in environmental regulation and field infrastructure

Contamination of pesticides, which are applied to rice paddy fields, in river water has been a major problem in Japan for decades. A prolonged water holding period after pesticide application in paddy fields is expected to reduce the concentration of rice pesticides in river water. Therefore, a long monitoring campaign was conducted from 2004 to 2010 to measure the concentrations of pesticides in water samples collected from several points along the Chikugo River (Japan) including tributaries and the main stream to see if there was any reduction in the level of pesticide contamination after the extension of the water holding period (from 3–4 days to 7 days) was introduced in 2007 by the new water management regulation. No significant difference (p > 0.05) was found in pesticide concentrations between the periods before and after 2007 in all monitoring points, except in one tributary where the pesticide concentrations after 2007 were even higher than that of the previous period. A detailed study in one of the tributaries also revealed that the renovated infrastructure did not reduce the pesticide concentrations in the drainage canals. Neither the introduction of the new regulation nor the improved infrastructure had any significant effect on reducing the contamination of pesticides in water of the Chikugo River. It is probably because most farmers did not properly implement the new requirement of holding paddy water within the field for 7 days after the application of pesticides. Only tightening the regulation would not be sufficient and more actions should be taken to enforce/provide extension support for the new water management regulation in order to reduce the level of residual pesticides in river water in Japan.
