Chinese Cities: Citizen participation in developing resilient and eco-friendly cities

HOW TO NAVIGATE THIS CASE STUDY: First, please refer to the Teacher's Guide using the yellow "View Materials" button on the left pane. The teacher's guide outlines the purpose, contents, approach, case structure, and technical information of this case study. This case study was curated from other independently published open educational resources and from existing materials on this platform. These resources are also organized by domain. At the bottom of each resource's page, you can see both the city case study and SURF Resilience domain to which it belongs. Click on the case study or the domain name to navigate to the case study homepage or SURF Resilience collection, respectively. OVERVIEW: This case study contains a teaching guide, five thematic foci, and a gaming simulation. In this case study, you will dive deeper into the resilience and sustainability in Chinese cities. You will see how issues like air pollution affect citizens' daily lives and how successful policies contribute to sustainability. With a high rate of urbanization, Chinese cities have resorted to using the Sponge City concept to successfully manage water. To deepen your knowledge, you can learn about other shocks and stresses facing Chinese cities in resilience trend reports. Finally, you can bring your knowledge into practice by diving into the game “Creators of Shanghai” which has been developed by TU Delft students.

Creators of Shanghai

In this game, you will play as an official in the Shanghai Planning Office, responsible for one of the four available ministries governing the urban centre. Your goal is to develop the city of Shanghai. As you play, shocks and stresses will affect the city, and you and your teammates must build resilience to prevent its decay. The game must be played by 4 people, since each ministry is essential. Every round represents 5 years. In a round, all four players can buy cards, implement solutions through measures taken, and mitigate the effects of shocks and stresses. Each round a shock strikes the city by chance, so you must be prepared.

Air pollution in Shanghai

This paper uses Shanghai as an example to analyze urban resilience in relation to the potential shocks and stresses caused by air pollution. Shocks such as smog and acid rain may cause damages to the economy, community and environment of the city. Stresses, on the other hand, will affect the city in the long run. It is also more difficult to remove stresses from the urban systems in comparison to shocks. For air pollution in Shanghai, stresses could be climate change, increasing population, increasing vehicle demand, and increasing emissions due to economic growth. Multi-level solutions are proposed in this paper targeting the shocks and stresses. At personal level, the importance of Personal Protection Equipment (PPE) and Environment Health and Safety (EHS) policies is discussed; at national level, enforcing environmental tax and investing in New Energy Vehicles (NEV) would also help to reduce the effects of shocks and stresses. In addition, some practical engineering solutions are introduced. For further discussion, ethical issues implied in this paper are raised. For example, some protective measures are suggested in the paper, but how to evaluate the implementation of these measures and how to ensure the vulnerable groups are protected when they are affected by the air pollution? To summarize, this paper focuses on the urban resilience in shanghai and includes topics about problems, solutions, and open discussions that are related to air pollution.

Heatwaves and Resilience in Shanghai, China

As one of the most densely populated cities in the world, Shanghai is especially vulnerable to heatwaves. The urban heat island (UHI) effect is heightening the severity of heat events in the centre which are occurring with increased severity, frequency and duration. The exorbitant swell in air conditioning usage among residents in response points to the need for more sustainable, resilient solutions. This report investigates the impacts of heatwaves relating to the current urban layout, climate change and waste management in Shanghai. Furthermore, the negative effects on the water supply, on human health and related ethical implications are analyzed. Proposed solutions are organized into impact and driving force solutions. Impact solutions consist of increased urban vegetation, the uptake of passive building principles and community-based care networks. Driving force solutions include decarbonizing the power supply, more stringent waste management systems and nutrient management improvements through education and new technology. Additional resources are provided on projected heat wave trends internationally, the evolution in the growth of Shanghai and on the potential for “cool roofing” to mitigate the UHI.

Solar flares in Shanghai

Space weather, specifically Solar super storms can wreak havoc on modern infrastructure. The impacts of the resulting geomagnetic superstorms are known in the electrical engineering community, but have since their discovery been systematically underestimated for equatorial latitudes. New insights imply the risk and impact on these regions are equal to the impact in polar regions and consist of; ionosphere saturation and geomagnetic fluctuations. These, when poorly managed or unexpected, will lead to loss of wireless communication capabilities and a breakdown of the power grid. These impacts and their planned preventions, as well as possible complications via cascading failure are laid out in this paper. In conclusion, very little can be said about Shanghai as the information is seen as of strategically value and thus is kept confidential. Initial damaged are partially avoidable, but long term impact will be unprecedented in the modern world.

Dredging Engineering: Special Topics

In dredging, production estimating is carried out mainly with analytical physical models of the different dredging processes. Slurry transport of settling slurries and cutting processes in sand, clay and rock are already covered in two other books by the author. Other processes like hopper sedimentation and erosion, water jet fluidization, cutter head spillage, pump/pipeline dynamics and clamshell dredging are covered in this Special Topics Edition. New topics may be added in the near future.
