Future & Long-Term Challenges
Water Scarcity, Drought & Climate Adaptation
TopicES
A live assessment of how this issue works in practice—institutions, tradeoffs, and what would improve outcomes. Evidence accumulates in our Summa.
Background
Why this remains an issue
- Spain is among Europe's most climate-exposed countries, facing growing drought, flood, and heatwave risks
- OECD's 2025 Spain survey highlights water pricing and protective infrastructure as adaptation priorities
- Water stress affects agriculture, tourism, cities, energy, insurance, public health, and inter-regional conflict
- Reservoir stress, wildfires, and heat waves make climate a lived governance test—not an abstract target
Core fault lines
- Agriculture vs cities: irrigation vs urban and tourist supply
- Tourism vs ecology: growth vs hard water limits
- Regions vs central: water sovereignty vs national drought planning
- Mitigation vs adaptation: emissions targets vs near-term protective investment
At a glance
Origin
Water scarcity is probably Spain's most important long-term resilience topic
Why now
Spain is among Europe's most climate-exposed countries, facing growing drought, flood, and heatwave risks OECD's 2025 Spain survey highlights water pricing and protective infrastructure as adaptation priorities
What to watch next
What water allocation and pricing rules are fair across regions and sectors? How fast can leakage reduction, reuse, and desalination reduce crisis frequency?

Analysis
Decision tradeoffs
- Agriculture vs cities: irrigation vs urban and tourist supply
- Tourism vs ecology: growth vs hard water limits
- Regions vs central: water sovereignty vs national drought planning
- Mitigation vs adaptation: emissions targets vs near-term protective investment
Working view
- Water scarcity is probably Spain's most important long-term resilience topic
- Hybrid policy combines efficiency, pricing, infrastructure, desalination, and drought planning
- Agricultural modernization must accompany water cuts with transitional support
- Climate adaptation requires regional fairness to sustain majorities beyond coastal prosperity
Deep intelligence
What could change our mind
- What water allocation and pricing rules are fair across regions and sectors?
- How fast can leakage reduction, reuse, and desalination reduce crisis frequency?
- Which crops and regions should bear adjustment costs?
- Can tourism growth continue under tighter water and heat constraints?
