This step summarizes the content of the first week on climate risks and cities (urbanization, urban adaptation, and telecoupling).
Well done! You have now successfully completed the first part of this course. Over the past week, we have jointly explored urbanization dynamics and their underlying drivers, we have discussed the complexity of urban adaptation practices and related global policy frameworks, and we have also taken a deeper look at the integrative concept of telecoupling, which can help us to better understand complex, interrelated urbanization processes.
The key messages to take with you into the next two weeks are the following:
refers to a variety of different processes. These include the topographic and demographic growth
of cities, either in absolute terms, or in comparison to rural areas. We can express urbanization levels by their degree and speed
, which both differ from time to time and place to place. As there is no general agreement on how to define cities, or clearly distinguish urban from rural areas, it is important that you first clarify for yourself what you mean when you talk about urbanization, based on what you have learned so far.
The immediate and underlying drivers of urbanization
also vary widely throughout time and across space. With regard to rural-urban migration, we can divide these various drivers into individual and collective ‘push’ and ‘pull’ factors
. Globally, agricultural and industrial innovations enabled and stimulated urbanization, but so did transport and communication, state formation, and many other factors and their complex interplay.
We have also seen that climatic changes
can influence both the rise and fall of cities. Urban areas currently face the serious challenge of adapting
to projected changes in temperatures, sea levels, and weather patterns. Distinguishing between the influence of these changes on urban hazards, exposure, and vulnerability
, helps in comprehensively reducing disaster risk
in cities. Successful climate change adaptation, ideally, leads to both disaster risk reduction and sustainable development
. It also reckons with the complexity of systemic linkages
that make up individual cities and their respective urban networks.
Global frameworks, such as the Sustainable Development Goals
and the New Urban Agenda
, provide a vision of successful adaptation in cities. However, they do not provide blueprints. Sustainable development goals and concepts such as urban innovation need to be translated into specific city and urban contexts.
The idea of telecoupling
can help you to better understand drivers of urbanization in context (social, economic, political, cultural, historical, ecological). Understanding how urbanization unfolds – and how it is connected across space and time – is a prerequisite for effective adaptation actions. When applied in practice, telecoupling toolboxes include a range of spatially explicit instruments for describing and quantifying multiple reciprocal socioeconomic and environmental interactions over distances.
Our activities during the second week will be focused on the following key topics in order to both deepen and broaden our knowledge of urban adaptation: we will further explore diverse urban systems
, discuss different approaches to urban governance and planning
, as well as the role of innovation and digitalization
for adaptation, for example in the context of the ‘smart city’
See you next week!
