🌌 How does light pollution affect biodiversity in the Wadden Sea?
When we talk about pressures on marine ecosystems, we often think of climate change, habitat loss, or overfishing. Yet another growing pressure — especially in coastal regions — is artificial light at night (ALAN).
The Wadden Sea, a UNESCO World Heritage Site and one of the world’s most productive intertidal ecosystems, is naturally governed by strong tidal and lunar rhythms. Many species here have evolved to depend on these cycles — and artificial light is beginning to disrupt them.
🐟 Fish and migration pathways Juvenile fish moving through tidal channels use natural light cues for orientation. Artificial lighting from coastal infrastructure, ports, and settlements can disorient them, potentially altering migration routes and survival rates.
🦐 Food web disruption in a dynamic system The Wadden Sea’s food web is tightly linked to plankton dynamics. Artificial light can concentrate plankton near illuminated areas, reshaping feeding opportunities for fish, shrimp, and birds — and changing predator-prey interactions in ways we are only beginning to understand.
🐦 Impacts on coastal birds Waders and migratory birds relying on the Wadden Sea’s tidal flats can be disturbed by night-time lighting, affecting resting, foraging, and migration behaviour across flyways.
🦀 Behavioural shifts in benthic species nocturnal and light-sensitive species such as crustaceans may change their activity patterns or avoid illuminated areas altogether, leading to shifts in habitat use and ecosystem functioning.
💡 Why this matters for the Wadden Sea Even subtle changes in light regimes can cascade through this highly interconnected ecosystem — influencing biodiversity, ecosystem resilience, and the services this unique landscape provides.
🌍 Working towards darker skies: DARKER SKY - Interreg North Sea Project The Darker Sky Project addresses light pollution in coastal regions, ports, and municipalities, including the Wadden Sea, by improving scientific understanding and supporting practical solutions such as smarter lighting design, reduced light intensity, and better spatial planning.
We at the Common Wadden Sea Secretariat (CWSS) are proud to be project partners in this initiative, working together with regional and international stakeholders to better understand and reduce the ecological impacts of light pollution in the Wadden Sea region.

On the occasion of the Urban 7 international summit, held in Nancy as part of the French G7 Presidency, Agora Makers is proud to contribute to the collective reflection on the major challenges shaping the cities of tomorrow. 🌍
Climate transition, evolving urban uses, resilient public spaces, mobility, quality of life and territorial attractiveness: today’s urban challenges call for cross-disciplinary approaches combining design, innovation, sustainability and services.
Within this dynamic, Agora Makers, alongside its brands and partners, will present an urban demonstrator installed in the heart of Nancy. Conceived as a real-scale experimentation space, this project embodies our vision of public spaces that are more adaptable, greener, smarter and more human-centered.
Because cities are no longer just infrastructures — they are places for interaction, shared experiences and new urban lifestyles. Shaping places together for the future. ✨
Light pollution is often invisible to us — until we realize what we’ve lost.
From disrupted ecosystems to impacts on human health, artificial light at night is reshaping our environment in ways we don’t always notice. Yet, understanding the scale of the problem is the first step toward meaningful change.
👉 This report, prepared by a consultancy firm commissioned by the Department of Environment of the Flemish Region, dives deep into the current state of light pollution in Belgium, uncovering key insights, data, and implications for the future.
✨ Imagine a future where: • Night skies are visible again • Biodiversity thrives undisturbed • Cities balance safety with sustainability
This report shows how we can move closer to that reality.

The range of sensitivity in the human eye is astounding. In full sun, we might be looking at an object lit to almost 100,000 lux, whereas at night the strength of moonlight typically reaches a miniscule 0.3 lux. Before the advent of artificial light, people have been able to use this seemingly negligible level of light for everything from harvesting crops, fishing, long distance travel and community gatherings. Some nocturnal animals are even able to use just the light that comes from the stars and the Milky Way on a moonless night - just 0.001 lux.
All this means that as ecological lighting designers we're often working with light levels in the sub 1 lux range, and when we carry out a baseline lighting survey for example, we usually take measurements on a moonless or overcast night. This ensures that the tiny (but important) contribution of moonlight is excluded from the calculation.

The smartphone in your hand has built-in imaging and communications systems that can be used for real scientific measurement.
This #lightday2026, we are inviting educators and organisers to explore our hands-on resources and find out how one can use smartphones to perform scientific measurements with simple apps and add-ons.
Night-time economy can be a strong driver of social and economic growth, also in cities across the Global South.
As in many other countries of the region, also in Hanoi night policies can contribute to urban attractiveness, and to broader social, economic and environmental development. #nighttimedesign #urbanlighting
