Tomorrow’s Cities Decision Support Environment (TCDSE)
The TCDSE comprises 6 components. Click on each of them to learn more.
Hazard & Impact Modelling
Urban Scenarios
Risk Agreement
Future Visioning
Impact Pathways
City Scoping
Hazard & Impact Modelling
In the Hazard & Impact Modelling component, teams identify relevant natural hazards for a specific location using historical records, stakeholder input, field surveys, and other sources. Computational models then simulate probable future hazard events—earthquakes, floods, landslides—on the Urban Scenarios from the previous component. This allows for calculating hazard characteristics and assessing impacts on physical infrastructure (buildings, bridges) and the social fabric (displacement, healthcare access). The modelling helps diagnose risk drivers through complex causal chains in urban decision-making.
Impact Pathways
The final TCDSE component is designed to deliver detailed Action Plans that facilitate collaborative city shaping, involving civil society and government actors at various levels. These plans also ensure a commitment to implementing the lessons learned. The broader ambition is for pro-poor, participatory, risk informed planning to become a sustainable feature of decision-making cultures.
Risk Agreement
The Risk Agreement component encompasses a series of activities that re-engage stakeholders and encourages them to evaluate the Urban Scenarios derived from Future Visioning after they have been subjected to the multi-hazard simulations conducted in the Hazard & Impact Modelling component. It is designed to co-produce an agreed understanding of risk amongst stakeholders. The process includes interactive workshops that simplify risk communication, facilitate evidence-based discussions, and identify feasible Urban Scenario revisions. This approach ensures that diverse perspectives, especially from marginalised communities, are incorporated into decision-making processes.
City Scoping
At the outset of the TCDSE activities, cities are encouraged to assess their existing data on both the physical environment (such as hazards, geographical context, and infrastructure) and the social environment (including demographics, social groups, and power imbalances). During this crucial mapping exercise, city teams focus on identifying key stakeholder groups, with special attention given to marginalised communities. This process involves a comprehensive review of data, policy, and planning frameworks to ensure a coordinated approach that incorporates multi-level governance.
Future Visioning
Future Visioning is a creative and interactive approach that allows urban planners and decision-makers to understand the aspirations of various social and community groups. Through participatory workshops, city stakeholders explore desired urban futures, land uses, critical urban assets, and policies to address the negative impacts of future natural hazards. From the workshops, stakeholders produce land-use sketches - Future Visions.
Urban Scenarios
The Urban Scenarios component involves translating the Future Visions developed by each stakeholder group into digital land-use plans and policies. These plans incorporate disaster risk reduction policies chosen by participants and are enhanced by future exposure datasets generated by technical teams. In a series of workshops, stakeholders challenge technical interpretations, discuss planning trade-offs and assess the equity consequences of decisions. This process innovates by integrating community-based ideas with science-guided information.
