01Resource scarcity
Water Stress
Apply a 25% water reduction and inspect access, stress, trust and cooperation.
Scenario library
Start with a policy experiment.
Each scenario is a real simulator preset. Open one to inspect assumptions, change parameters, and run it.
02Housing
Affordable Housing
Model a housing cost change in a more unequal city and examine how access and inequality respond.
03Mobility
Public Transport Subsidy
Test a targeted mobility subsidy in a dense synthetic city and inspect access and institutional outcomes.
04Resource scarcity
Energy Rationing
Stress-test constrained energy availability and observe downstream effects of scarcity.
Why presets?
Comparable starting points.
Presets keep the first experiment reproducible while leaving the policy, population size, rounds and seed editable. Trust and cooperation are synthetic behavioural states that respond to policy experience and local interactions—not observed measures of real people.
