The Socio-Technical Context of Kampala's Water Chain

Dr. Bas van Vliet introduces the water chain in Kampala, which is exemplary of other cities in the Global South. He will show you the drinking water system and the diversity of sanitation systems in the serviced and unserviced parts of the city. Being one of the fastest growing cities in the Global South, Kampala’s water chain is a co-production of various users and providers, and it is radically different from water chains in the Global North.

Water Hygiene in Maputo, Mozambique

The report looks into the problem of water hygiene in Maputo considering the effect of climate change and summarizes the potential solutions. The report is composed of six parts. The first part of the report describes the three main problems which are shortage and contamination of drinking water, failure of groundwater systems, and poor waste management. This part also discusses how climate change may exacerbate the problems. The second part summarizes the strategies proposed or being implemented by Mozambique’s government or international organizations. These mainly include constructing reservoirs and drainages, strengthening sanitary facilities, and enhancing resistance to cyclones. The third part provides some critical further literature to deeply understand Maputo’s adaptation and mitigation strategies. The fourth part asks five questions that readers can answer after reading this report while the fifth part provides the answers giving by the author. The sixth part challenges the readers with three more questions that intend to spark discussion among them.

Urban Water Chains and Systems

This set contains 4 short videos on urban water chains and systems. Water is a basic, universal need. In this set of materials, you will learn what an urban water chain and urban water system contain. The urban water chain refers to drinking water provision and sanitation, along with necessary infrastructure. The urban water system expands upon the water chain to include five types of urban water: surface water, groundwater, drinking water, wastewater, and stormwater. Within an urban water chain and system, stakeholders manage and modify the water cycle, giving opportunity for citizens to co-create a safe and healthy living environment. Furthermore, you can learn about how politicians and stakeholders can think about long-term decision making and governance within usually short election cycles. These videos and materials will give you a baseline understanding of how sustainable solutions to water-related problems are co-created with citizens. These concepts can be applied to specific case studies and various local contexts around the world. Finally, you can apply this knowledge in a role-playing game where you attempt to set up a drinking water management system and decide between whether to organize the drink water supply as a public or private entity.

Waarom ga je dood als je te veel water drinkt?

“Drink genoeg water”, wordt er weleens gezegd. Maar kan je ook te veel drinken? Ja, dat kan. In deze aflevering legt arts-onderzoeker Dipti Rao van het Radboudumc uit waarom water in grote hoeveelheden zelfs dodelijk kan zijn. En waarom situaties als drugsgebruik je hier extra gevoelig voor maken. Deze video is opgenomen door de Universiteit van Nederland: https://www.universiteitvannederland.nl/

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.

Droughts in Rotterdam

With Climate Change, the frequency and intensity of droughts hitting the city of Rotterdam is increasing with time. 2019 was the third consecutive dry year in a row. With drought, comes a number of problems such as low water level in the Maas river which is the biggest source of drinking water for the city of Rotterdam (80%) and it effects the water quality, reduction in shipping capacity, weakening of dikes, salt intrusion, lowering of groundwater level which could lead to subsidence, etc. A concept map provided in the report highlights the STE (Social, Technological & Ecological) impacts of droughts on the city of Rotterdam. Possible solution practices include increasing the infiltration capacity of the city through blue-green networks, bioswales, vertical gardens, spraying water on dikes, building rainwater harvesting and storage infrastructure. Importance should also be given to the ethical implications of the solution strategies and also the usage of monitoring techniques to help mitigate any adverse effects of a potential disaster. The report also includes some links for further reading which covers a wide horizon of topics related to the effect and mitigation of droughts on the city of Rotterdam and the scope of public private responsibilities for climate change.

Land subsidence in Jakarta

The most threatening stress of Jakarta is the land subsidence following the rise in sea levels and river/coastal flooding. There is increased risk of flooding and land stresses in the densely populated areas of Jakarta, which lead to increased land subsidence and due to the improved standards of living and earning of their people, ultimately leading to over-population in the coastal and in the entire city area of Jakarta, respectively. There is a need of proper waste management system, also to diminish the risk of agriculture/crop failures. The main solution responsibility lies in the hands of the Government while implementing their policies by proper cooperation and coordination with the various stakeholders as well keeping the residents of Jakarta aware and informed. Proper drainage systems, proper placements of Dykes in necessary areas, and encouraging the residents to construct local water storage bodies in their homes targeting rainwater harvesting would be some of the main solution strategies. There will be an increase in the demand for meeting the GDP caused due to the rehabilitation costs or costs related to relocation of the people to less-stressed areas. Strict monitoring of the areas undergoing land subsidence, environmental checks in the industries, making the migration procedures much more rigid and strict, putting checks in people who completely depend on groundwater and encouraging them to use alternative methods for collecting drinking water should be the main target for the settlement of such stresses.

The Rest Is History | 346. The Mystery of the Holy Grail (Part 2)

“Who drinks the water I shall give him, will have a spring inside him welling up for eternal life.” A deeply mysterious object which doesn’t appear in the Bible, was the Holy Grail really the chalice used by Jesus during the Last Supper, and the very cup that caught his blood at the crucifixion? Or is it merely a symbol representing Christ’s bloodline? Join Tom and Dominic as they discuss the Holy Grail, the origin of the tradition, and the role it played within medieval Christendom.
