Light and noise pollution are growing #environmental issues and recognised threats to biodiversity. Yet, they often receive far less attention than they deserve.

As part of the PLAN-B Project, we are conducting a survey to better understand public attitudes towards light and noise pollution, how they compare to other environmental challenges, and how acceptable different mitigation measures might be.

This online #survey forms part of a wider study exploring the social and psychological factors influencing these issues. It is led by our colleagues Michael Lomas PhD and Graeme Sherriff from The University of Salford, and takes approximately 15 minutes to complete.

𝐖𝐡𝐚𝐭 𝐝𝐨 𝐰𝐞 𝐧𝐞𝐞𝐝 𝐟𝐫𝐨𝐦 𝐲𝐨𝐮?

We kindly invite you to take part. Every response matters, and your insights will help us understand how people perceive light and noise pollution and what actions might be needed to address them.

How do these forms of pollution affect you?
What changes should be made?
What would you support?

The key wavelengths for human health are missing from most LEDs. In the race to provide the cheapest brightness (maximum lumens per watt), conventional LEDs fail to provide the vital 380 nm, 430 nm & 480 nm wavelengths that stimulate the non-visual opsins (light-sensitive proteins) in the eye essential for good health.

As explained in my Substack article https://lnkd.in/eTq4e42C our eyes were
designed to see light at:
~380 nm (Opsin 5: eye develop, myopia prevent & glucose regulation)
~430 nm (Opsin 3: eye development & glucose regulation)
~480 nm (Opsin 4: Melanopsin - circadian rhythm synchronization)
 
and our bodies were designed to absorb infrared light at:
~825 nm (direct stimulation of mitochondrial energy production)

Modern LEDs may do a good job of stimulating the Visual Opsins 1 (Color vision) & 2 (Rhodopsin night vision).

But they totally fail at providing light at the critical wavelengths essential for health.

It is time that LED manufacturers realize that light is not just about vision, it is also essential for health.

At first, it looks like a random pattern of lights: the United States glowing proudly from coast to coast.

But look closer.

There’s a line.

A straight, invisible divide cutting the country in two.

To the east: dense cities, farms, humidity, and growth.
To the west: dry lands, sparse lights, and silence.

That line isn’t political or cultural: it’s natural.

The 100th meridian, where the humid east meets the arid west.
Where agriculture once stopped, and survival changed shape.

Light pollution here becomes a climate map drawn by human hands: proof that even our chaos follows the rules of nature.


This is part of my Tuesday mini-series, exploring how our artificial light reveals the deepest patterns of life, wealth, and geography on Earth.

Light pollution is destructive. Yet, paradoxically, it tells the story of who we are. And while it offers us this anthropological lens, we must still fight it , for our health, our ecosystems, and our future.

💡 I’m available for lectures, webinars or talks on light, the human body, Human Centric Lighting, sustainability and yes, even light pollution.
If you’d like to explore these topics outside the usual clichés, feel free to contact me.

GO W.A! I’m blown away by how much effort, funding and activity is being invested in dark skies across Western Australia. It really looks like you’re leading the W.A.y.

From world-class astrotourism experiences to immersive education at Scitech, Western Australia is showing how communities, science and tourism can come together to protect one of our most precious natural assets: the night sky.

The new Light Pollution exhibit at Scitech’s Here, There and Everywhere gallery is a powerful example. Visitors can experience the impact of light pollution on turtle hatchlings and the stars above, while learning how small changes in the way we use light can make a big difference for wildlife and future generations.
It’s inspiring to see this kind of leadership.

With initiatives like this, W.A. isn’t just protecting its skies – it’s setting a benchmark for the rest of Australia (and the world).

Great work Carol Redford Tristan Simpson and Scitech

Tired of an increasingly boring academy? Well, there is always hope (for the time...). If you want to participate in two initiatives that will shape the future of studies on nocturnal cities and nighttime tourism, I invite you to send your proposals to:

1) Call For Abstracts Proposals: "The Palgrave Handbook on Nocturnal Cities", edited by Dr. Manuel García Ruiz (ISCTE–IUL) & Dr. Jordi Nofre (NOVA FCSH) 
https://lnkd.in/dMX6DyWz
This forthcoming volume (expected publication mid-2027) explores the multiple dimensions of nocturnal urban life—its atmospheres, economies, inequalities, and transformations. Extended deadline: 15 November 2025.

2) Call For Papers: Special Issue of Tourism Geographies (Q1) "After Dark – Exploring Nighttime Tourism in Tourism Geographies (Special Issue)". Guest Editors: Dr. Manuel García Ruiz (ISCTE–IUL) & Dr. Jordi Nofre (NOVA FCSH)
https://lnkd.in/dAkvyu3n
Tourism studies have long focused on daylight experiences — yet the night is increasingly becoming a vital space of touristic, cultural, and affective practices. From light festivals and open-air concerts to gastronomic trails, pilgrimages, queer nightlife, and stargazing, this special issue foregrounds the night as a crucial analytical lens for understanding contemporary tourism geographies. We invite contributions exploring: Cultural, creative, and event-based tourism after dark; Nocturnal atmospheres, rhythms, and affective practices; Governance, sustainability, and aesthetic economies of the night; Comparative and interdisciplinary approaches to nighttime tourism. Deadline: 15 November 2025

Artificial light at night not only increases emission of CO2 as of high electricity demand but has also other - until now - unknown effects on climate change. 
"Artificial Light At Night" (ALAN) is increasing carbon released by plants and animals across continents—without any increase in the carbon they absorb.

An interactive visualization from Our World in Data.

Did switching off street lights at night increase crime—or reduce it?

Dr Phil Edwards from the London School of Hygiene & Tropical Medicine, lead of the LANTERNS Project, shares new NIHR-funded research showing that streets with part-night lighting saw vehicle thefts drop by half compared with before the change.

Using 10 years of Thames Valley police data, the study explored how part-night lighting, dimming, and white light affected burglary, robbery, vehicle crime, and violence—challenging assumptions that more light means more safety.
Join this webinar to discover how smarter, evidence-based lighting can cut energy use while keeping communities safe.

Our collegue and scientific coordinator of PLAN-B Project Yana Yakushina has participated in the last podcast of Light Pollution News, and interesting conversation about raising awarness of #lightpollution.

She quotes at Frank Turina, PhD when he says "𝘊𝘰𝘮𝘣𝘪𝘯𝘨 “𝘭𝘪𝘨𝘩𝘵” 𝘢𝘯𝘥 “𝘱𝘰𝘭𝘭𝘶𝘵𝘪𝘰𝘯” 𝘤𝘩𝘢𝘯𝘨𝘦𝘴 𝘩𝘱𝘸 𝘱𝘦𝘰𝘱𝘭𝘦 𝘵𝘩𝘪𝘯𝘬 - 𝘴𝘶𝘥𝘥𝘦𝘭𝘯𝘭𝘺, 𝘺𝘰𝘶 𝘳𝘦𝘢𝘭𝘪𝘴𝘦 𝘯𝘰𝘵 𝘢𝘭𝘭 𝘭𝘪𝘨𝘩𝘵 𝘪𝘴 𝘨𝘰𝘰𝘥". In her words, calling something “pollution” brings people’s attention to ALAN as a possible form of harm. After we get this attention, we can think how we can change or reduce light.

We invite you to listen to the podcast an leave your comments about this matter: having a clear "name" (such as "light pollution) help us to raise awarness of the issues that we want to address?

Combien peut-on économiser en éclairage public ?

Pour répondre à cette question, nous utilisons une plateforme cartographique de simulation simple et efficace, qui fonctionne en 3 étapes :

💡 identifier les sources lumineuses les plus #énergivores.
🔋 Indiquer la #puissance envisagée après rénovation.
📅 Indiquer la #durée de fonctionnement annuelle après rénovation.

Résultat ? Une comparaison #dynamique et #immédiate entre :

🪫La consommation énergétique actuelle et celle projetée.
💰Les coûts actuels et ceux projetés.

En vidéo, la démonstration sur la base de données de Nantes Métropole, disponible en #Opendata. On découvre que :

⚡L'échantillon de 200 points lumineux sélectionnés indique une #puissance moyenne par point de 416,3 W, soit 364 670 kWh/an si l'on part du principe que c'est un éclairage #permanent.

💲Le #coût de l'énergie actuellement consommée par ces 200 sources est de 91 167,5 €/an sur une base de 0,25 € du kWh, sans compter les frais d'abonnement, d'acheminement ou encore de maintenance.

↘️La consommation #énergétique annuelle descend à 43 800 kWh/an et son coût à 10 950 €/an, sur la base des mêmes indicateurs (régime permanent, 0,25 € du kWh), si l'on prend une puissance moyenne de #50W par source pour la #rénovation, pour atteindre 88% d'économies.

⬇️La consommation énergétique annuelle atteint 14 600 kWh/an, et son coût 3 650 €/an si l'on couple la puissance moyenne de rénovation de 50W à une pratique d'#extinction en cœur de nuit, pour atteindre 96% d'économies.

🎯L'objectif de la plateforme ? #Accompagner les décideurs et services des collectivités dans l'optimisation des choix et #financements de la rénovation de leur éclairage public, en leur permettant d'accéder à une vision #géographique immédiate des #priorités énergétiques, et des #économies accessibles.

Et dans votre ville, quelles sont les économies accessibles ? Testez dès à présent le démonstrateur, il est gratuit et ouvert à tous !
