Stop fighting the river, make room for it

Greece has the tech. Greece has the talent. Now it needs to de-waterproof its cities, at speed.

The plan

• €2.5B → a 30-year national water strategy (launched in 2025) managing water scarcity and flood risk

• €1B+ → Thessaly: watershed projects (€200M), 3 major dams (€600M), Pineios River works (€50M)

• €355M → Athens/Thessaloniki/Peloponnese: canalised streams, drainage, green spaces for 600 hectares

• €105M → Rafina Stream upgrade with new debris retention basins to protect against flash floods

• AI integration → "Flood Protection 2" implements AI to track stream flows, monitor flooded roads in real-time, and trigger early warnings

The problem

Despite the budget, execution lags. Between Storm Ianos (2020) and Storm Daniel (2023), just 1.6% of the planned €4.5B in flood interventions was delivered.

Why? Bureaucracy. Clearing a single riverbed, a 2–3 month job, takes 2 years.

The blueprint

• Spain (Valencia DANA, 2024): €50B+ damage → €530M plan approved in 7 months

• Portugal (Atlantic storms, 2026): €4B+ damage → €187M river restoration launched in 3 months

• The Netherlands (1995): 'Room for the River' → 30+ nature-based projects worth €2.3B. Instead of building higher flood walls, they moved dikes inland and restored floodplains, adding 300km² space for rivers, reducing peak water levels by 35cm and protecting ~11 million people.

The bottom line

The Dutch proved: give rivers space, not walls. Greece's EIB-backed nature-based solutions (2.9x returns) and AI warnings point the right way.

Spain and Portugal prove the pace is possible. The plans exist. Time to cut the bureaucracy.
