Why PM Modi visited Netherlands’ Afsluitdijk dam: The Dutch model India may need

What Happened
- During the India-Netherlands bilateral visit in May 2026, the Indian Prime Minister toured the Afsluitdijk — the Netherlands' iconic 32-kilometre sea barrier that closed off the Zuiderzee from the North Sea in 1932 — as a symbolic and substantive statement of India's interest in Dutch water management expertise.
- The visit directly preceded the signing of a Letter of Intent (LoI) between India's Ministry of Jal Shakti and the Netherlands' Ministry of Infrastructure and Water Management for technical cooperation on the Kalpasar Project, India's proposed mega-dam across the Gulf of Khambhat in Gujarat.
- The Kalpasar Project envisages a 30-kilometre dam across the Gulf of Khambhat to create the world's largest freshwater reservoir in a marine environment, with a storage capacity of 10 billion cubic metres — equivalent to approximately 25% of Gujarat's average annual rainwater runoff.
- Dutch expertise in delta management, polder technology, sea-barrier construction, flood control, and freshwater storage is globally unmatched and directly applicable to the Kalpasar challenge of closing a tidal estuary while managing river inflows from the Narmada, Mahi, Sabarmati, and Dhadhar rivers.
- India-Netherlands cooperation on water management was placed within the 2026–2030 Bilateral Cooperation Roadmap as an integrated thematic pillar covering water resource management, flood resilience, and climate-resilient agriculture.
- The LoI is the institutional bridge that allows India to access Dutch technical knowledge accumulated over nearly a century of Zuiderzee Works experience for one of its most consequential infrastructure projects.

The Afsluitdijk and the Zuiderzee Works
The Afsluitdijk (Dutch: "Enclosure Dike") is the centrepiece of the Zuiderzee Works, described by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World (along with the Delta Works). Designed by Dutch civil engineer Cornelis Lely in 1891, construction began in 1927 and the dike was completed on 28 May 1932 — two years ahead of schedule.
- Length: 32 kilometres; Width: 90 metres
- It runs from Den Oever (North Holland) to Zurich (Friesland), dividing the former Zuiderzee into the IJsselmeer (freshwater lake) and the Wadden Sea (tidal sea).
- The project required 10,000 workers, 27 large dredges, 13 floating cranes, 132 barges, and 88 tugs at peak construction.
- The closure was triggered by the 1916 flood (storm surge) and the 1918 famine, which together built political consensus for the project.
- The reclaimed land (polders) added approximately 1,650 sq km to the Netherlands' territory, while the IJsselmeer became a critical freshwater reservoir for agriculture and drinking water.
Connection to this news: The Afsluitdijk serves as the direct conceptual and engineering model for the Kalpasar dam — both projects involve closing a tidal inlet, converting salt water to fresh, creating a reservoir from rivers flowing into the sea, and simultaneously improving flood protection and enabling land use.
Kalpasar Project — Gulf of Khambhat Development Project
The Kalpasar Project (also called the Gulf of Khambhat Development Project) is a proposed multi-purpose infrastructure project in Gujarat, being developed under the state government with central support. It has been under consideration since the early 1990s.
- Dam length: 30 km across the Gulf of Khambhat (Cambay) in the Arabian Sea.
- Freshwater storage: 10 billion cubic metres — fed by six rivers: Narmada, Mahi, Dhadhar, Sabarmati, Limbdi-Bhogavo, and others.
- Estimated cost: ₹90,000 crore (2015-16 estimates; inflated significantly since).
- Multi-purpose benefits: Freshwater reservoir, tidal power generation, a 10-lane road link connecting Saurashtra and South Gujarat (drastically reducing travel distance), land reclamation, and fisheries development.
- The project would create conditions for Dholera Smart City and industrial corridors in the region.
- A Bhadbhut Barrage on the Narmada river and a connecting canal are additional components.
Connection to this news: The LoI with the Netherlands brings proven Dutch engineering methodology to a project that has long awaited a technical partner capable of managing the complex hydraulics of a tidal bay closure on this scale.
Polder Model and Dutch Water Governance
The Netherlands has developed a unique system of governance for water management — the Waterschap (Water Board) system — which is one of the oldest democratic institutions in the world, predating the national parliament. The "polder model" in Dutch governance refers to consensus-based decision-making, originally developed to manage shared water infrastructure where neighbours had to cooperate or all would flood.
- About 26% of the Netherlands lies below sea level; without active water management, 65% of the country would be regularly flooded.
- The Delta Works (a post-1953 flood engineering programme) consists of a series of dams, sluices, locks, dikes, and storm surge barriers in the Rhine-Meuse-Scheldt delta — also a Seven Wonder of the Modern World.
- The Netherlands' National Delta Programme (launched 2010) is a model for climate adaptation — integrating flood safety, fresh water supply, and spatial planning.
Connection to this news: India's collaboration with the Netherlands on Kalpasar brings not just engineering but a governance and planning philosophy for complex water infrastructure.
Key Facts & Data
- The Afsluitdijk was completed 28 May 1932 — two years ahead of schedule.
- The Zuiderzee Works, together with the Delta Works, are listed among the Seven Wonders of the Modern World by the American Society of Civil Engineers.
- Kalpasar's reservoir (if built) would be the world's largest freshwater lake in a marine environment.
- The Gulf of Khambhat receives waters from 6 rivers including the Narmada and Sabarmati — giving it a very high freshwater inflow potential.
- The proposed Kalpasar dam would include a 10-lane road-rail corridor connecting Saurashtra to South Gujarat, significantly reducing transit times.
- The Kalpasar LoI was signed between Ministry of Jal Shakti (India) and the Netherlands Ministry of Infrastructure and Water Management.
- India and the Netherlands already cooperate on water management under the India-Netherlands Joint Working Group on Water established earlier; the Kalpasar LoI deepens this to a project-specific technical partnership.
- 26% of the Netherlands is below sea level; water management is a core national competency built over 800+ years.
