Climate Resilience: Drought and Flood Risk in Amsterdam

Executive overview

Key findings

EUR 1.04 billion: investment needed for Amsterdam to meet its 2050 adaptation goals (needs assessment, September 2025; goals not formally adopted)

EUR 1.18 billion to EUR 3.46 billion: extreme-weather damage expected in Amsterdam over 2018–2050 without the measures (estimate)

EUR 3.0 million (2027) rising to EUR 5.0 million a year (2028–2030): extra funding for "climate adaptation and green" in the 2026–2030 coalition agreement

80% against 90%: regional dikes meeting their standard in 2025, against the water authority's 2030 target (whole water authority area)

Buyer relevance

Who the report is for

Suppliers of green-blue infrastructure and tree care

Size the city's stated need, including about EUR 355 million to protect some 71,000 drought-vulnerable trees, against the funding agreed so far.

Dike and civil contractors

Plan for the water authority's second regional dike programme, planned to rise to EUR 18.0 million a year from 2028 with measures due by 2030.

Developers, housing corporations and their insurers

Weigh cloudburst, heat and foundation exposure, including about 23,000 vulnerable foundations, against the city's 70,000-home target to 2040.

City, provincial and national policy teams

Compare the EUR 1.18 billion to EUR 3.46 billion damage estimate with funded measures ahead of the 2027 budget and the national drought evaluation.

Decision scope

Questions answered

How much does Amsterdam need to invest to adapt to climate change?

EUR 1.04 billion to 2050 plus about EUR 20 million a year in maintenance, on a September 2025 needs assessment whose goals the city has not formally adopted.

How much has the new city coalition set aside?

EUR 18.0 million for climate adaptation and green over 2027–2030 (calculated from EUR 3.0 million in 2027 and EUR 5.0 million a year from 2028), plus EUR 11.0 million for trees.

Are Amsterdam's dikes up to standard?

All primary defences met their standard in 2025; 80% of the water authority's regional defences did, against a 90% target for 2030.

What happened in the 2026 drought?

The Netherlands was in an official actual water shortage from 16 July to 3 September 2026, and salinisation in the Amsterdam-Rijnkanaal and Lek remained a concern on 3 September.
