Towards closing the urban Water Cycle - Technologies and Case Studies
Punktzahl: 3,0 LP
According to the United Nations over the next 25 years the world’s population is expected to reach 8 billion, with 5 billion living in urban areas. More than half of the 8 billion will face water shortages and 40% of the urban population might be living in informal settlements. Billions of people, in urban and rural areas, have no proper sanitation and water supply. Thus proper solutions to integrate new water concepts into urban planning are needed in a world where most people will live in cities despite the increased urban poverty rates.
In this seminar we will do research on the numerous factors that cause water scarcity and sanitation problems in different parts of the world. We will address the challenges of the relationship between health effects of poor sanitation, water shortage and pollution, food insecurity, urban growth and the inadequacy of current sanitation options. By studying different case-studies and applied technologies, we will learn about different concepts of ecological sanitation which help to save water, do not pollute the environment, return the nutrients in human excreta to the soil, save money and optimise the financial resources of many communities around the world.
Based on an understanding of the technologies that can be applied, we will explore their potentials in relationship with sustainable building construction, urban form and human lifestyles. We will design scenarios for a new water culture in arid climates in order to demonstrate infrastructural/architectonic relations to our urban environments. The seminar will be organised in the form of a compact-seminar parallel to the project “Lima: Beyond the Park II“ and will contribute to develop strategies for the implementation phase in Lima during the summer school.
