Designing Water-Scarcity Policy

You are advising a regional government facing persistent water shortages after repeated heatwaves and low rainfall. Build a practical policy playbook that balances household needs, farming, industry, and environmental protection. Include short-term emergency measures, medium-term infrastructure choices, demand-management tools, and long-term adaptation strategies. Compare the trade-offs of water rationing, reservoir management, leak reduction, crop shifts, pricing reforms, and reuse of treated wastewater. End by proposing which measures are most politically feasible and which are most effective under worsening climate stress.
