Flood defence management and climate change: Towards a climate-smart solution
Coastal areas are strongly affected by extreme weather events such as storm surges and the consequent flood events. On a global level, the risk of coastal floods is projected to increase under global warming due to rising sea-levels. Concerning that, levees do not necessarily constitute the best adaptation option. Societies have developed alternative flood evasion measures to managed retreat. Assessments of the effectiveness of different coastal adaptation strategies remain limited and become more relevant under climate change. Moreover, evaluating these adaptation measures from a physical perspective alone is not sufficient, as these also strongly influence social behaviour regarding risk perception and autonomous adaptation. Communities and countries differ in the way they cope with flood events and how they adapt to rising sea levels. Nevertheless, societies can learn from past events and from each other in order to reach evidence-based, climate-smart decision making. This is where this project aims to contribute.
Policy and Innovation Spreading on the Global City Network
In their struggle for sustainability, cities learn innovations (such as climate targets and public transport policies) from each other. In this process, cities can be conceptualized as nodes on a globe-spanning network, interconnected e.g. by infrastructure, trade, and the exchange of people. I would like to present my work on modeling the spreading of several municipal sustainability policies and innovations as contagion processes on such inter-city networks.
Can trajectories of vulnerability to climate change be mapped? Insights from a national-level study for Ethiopia
Vulnerability assessment form the basis to decide ‘what’ climate change adaptation measures are needed ‘where’. It offers a lens to account for geographical differences in socio-economic, biophysical, and climatic variables. However, characterization of vulnerability using indicator-based studies is limited to one-time snapshot (mostly of current) and, so far, studies insufficiently address the dynamics of the vulnerability over time. The talk presents the challenges in mapping temporal dynamics of the vulnerability, and presents results of a spatio-temporal vulnerability assessment for smallholder agriculture system in Ethiopia.
There will be time for Q&A and discussion afterwards.
