Summary

Scenario planning in urban sustainability involves the systematic exploration of multiple plausible futures to inform decision-making, policy design and adaptive governance. Originating from strategic foresight in corporate management, the approach has been adapted to urban contexts to address deep uncertainties arising from climate change, rapid urbanisation, social inequality and technological disruption. Rather than seeking a single “optimal” future, scenario planning equips stakeholders with contrasting narratives and quantitative projections, allowing them to test the robustness of strategies under varied assumptions about demographic trends, resource availability, regulatory shifts and behavioural change. Techniques range from participatory workshops that engage citizens and experts in co-creating qualitative storylines, to advanced models that integrate land-use simulation, transport microsimulation and environmental impact assessment. By illuminating risks and opportunities across different time horizons, scenario planning promotes resilience and equity in urban development, guiding investments in infrastructure, mobility networks, green and blue space, energy systems and social services. Practical applications include the design of climate-adapted districts, the prioritisation of transit-oriented development corridors and the assessment of water-sensitive urban landscapes. Globally, scenario planning has gained traction as cities seek to reconcile short-term pressures with long-term sustainability goals, aligning municipal strategies with international frameworks such as the Sustainable Development Goals and the New Urban Agenda.

Scenario Planning in Urban Sustainability publication trend

The graph below shows the total number of articles in scenario planning in urban sustainability across all publications each year (not limited to Nature Index journals).

Technical terms

Scenario planning: A method for constructing and comparing multiple plausible future narratives and quantitative projections to test policies under uncertainty.

MICMAC scenario method: A structured foresight technique that identifies and analyses key driving factors and their interactions to generate coherent future scenarios.

Agent-based transport simulation: A modelling approach in which individual travellers or vehicles (“agents”) follow behavioural rules within a transport network to assess system-level performance.

Iterative design workflow: A cyclical process of rapid prototyping and testing, enabling planners to refine urban form and policy interventions through successive scenario evaluations.

About these summaries

This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
