🚨 Call for Papers – Special Issue in Tourism Geographies Journal
After Dark: Atmospheres, Temporalities, and Embodied Practices of Nighttime Tourism
I’m proud to announce the launch of a special issue that I am leading as Guest Editor, dedicated to exploring how tourism is shaped by—and shapes—the night. As Coordinator of the International Night Studies Network, my work has long centered on the multiple ways nighttime becomes a critical space for cultural expression, urban transformation, and affective experience. In this issue, I am joined by my colleague and co-editor Dr. Jordi Nofre (Coordinator of the LXNights Research Group), with whom I share a deep commitment to advancing Night Studies as a vital field of inquiry.
This special issue invites contributions on a wide range of nighttime tourism practices—from light art festivals and queer nightlife to astrotourism, nocturnal wellness, religious vigils, night diving, and night safaris. It aims to offer new insights into the rhythms, atmospheres, politics, and aesthetics of tourism after dark.
If your research is lighting up the night, we want to hear from you. Join us in expanding the boundaries of tourism geography—one nocturnal encounter at a time.
„Walking through neighborhoods, volunteers identified sources of light pollution…
Surprisingly, streetlights only made up 10.3% of all the light sources. Many (48.2%) were illuminated private windows, and commercial windows added another 7.4%. Other source types made up the remaining 18%, including illuminated signs, floodlights, facade illuminations, video screens, decorative lights, and illuminated house numbers and door bells.“
In the age of smart cities and sustainable development, traditional street lighting is rapidly being replaced by street light automation systems . These modern systems leverage cutting-edge technology to reduce energy consumption, improve safety, and minimize human intervention.

Call it a manifesto for welcoming, productive nighttimes -- for those of us who LOVE to go out (culture fiends) and those of us who MUST go out (shiftworkers). My article is a clarion call to reconsider the after dark hours as crucial and equal to the design and engagement that we reserve for the day, NOW.
This essay offers a playful, and maybe, improbable, big idea for urban heat adaptation. It is meant as a wake-up call to consider the everyday environment of night as a malleable, designable place, one which has been neglected by our cities’ urban planners, public health professionals, designers, and government administrators.
‘Day for Night’ is a classic cinematic technique to simulate a night scene while filming in daylight. Well known by filmmakers and aficionados, shooting during the day is less expensive and less arduous than working throughout the night. Film buffs will recall Dr. Zhivago, Pan’s Labyrinth, Dune, and Truffaut’s multi-award-winning ‘Day for Night’. In this essay, the term is flipped to ‘Night for Day’, advancing night as the new normal. The author means to guide the reader on an exploration of the transdisciplinary city after dark. The intent is to awaken civil society, the design professions, and those who govern public spaces to the criticality of night as a place. A cooler place than the day.

For billions of years, life on Earth evolved under natural darkness. But in just the last two centuries, artificial light has rapidly transformed the night, and not for the better.
“Life on Earth has evolved with natural darkness for at least 3.7 billion years,” says James Brigagliano, DarkSky’s Lighting Program Manager. “By contrast, human-made light has existed for only the past 200 years, with widespread light pollution emerging in just the last 75.”
Today, light pollution is growing by 9.6% every year, doubling roughly every eight years. That glow is putting fireflies, ecosystems, and our shared night at risk. ✨

Une étude scientifique pour montrer une appréhension différente de la marche la nuit.
Même environnement, mais Les femmes balayent la périphérie, les zones sombres. Les hommes, eux, regardent le centre un point de lumière, un point focal. Les femmes sont à l'affût de dangers potentiels, les hommes directement vers leurs destination.
Un bon design urbain, c'est celui qui rassure autant qu'il guide.

We are pleased to announce the launch of a new policy brief (https://lnkd.in/eV-xpT2u) developed by the PLAN-B Project and the AquaPLAN project.
Titled Restoring the Night, the brief builds on the 2023 European Light Pollution Manifesto (https://lnkd.in/ewNjNBnx) and outlines a strategic framework to address artificial light at night (#ALAN) as an emerging environmental issue.
𝐊𝐞𝐲 𝐟𝐚𝐜𝐭𝐬: ◾ 99% of Europe’s population and biodiversity live under light-polluted skies ◾ 30% of vertebrates and over 60% of invertebrates are nocturnal ◾ Light pollution contributes to an estimated $3.4 trillion in annual lost ecosystem service value globally
The brief calls for action through 10 𝐤𝐞𝐲 𝐫𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧𝐬, including: ◾ Recognising light pollution as environmental pollution ◾ Defining ecological limits for ALAN ◾ Establishing a coherent, harmonised EU regulatory framework ◾ Requiring monitoring, transparency, and data sharing ◾ Supporting education, awareness, and international cooperation
Since its launch in April, our light pollution policy campaign (https://lnkd.in/dE-76cWC) has received support from organisations including Buglife, the Università di Pisa, the Tyrolean Environmental Ombuds Office, and the Royal Astronomical Society, as well as individuals from over 40 countries.
We invite institutions, experts, and individuals to: ◾ Share the policy brief ◾ Join national and regional implementation efforts ◾ Support the campaign as an individual or organisation (sign the form: https://lnkd.in/dE-76cWC or contact us to get an official Support Letter) ◾ Help disseminate and translate the brief
We believe that with coordinated action, strong policy, and public engagement, we can ensure that artificial light is used responsibly, purposefully, and within ecological limits.
We thank everyone who was involved with us in developing the policy brief and policy action: Yana Yakushina, Professor Mike Wood, Alejandro Sanchez de Miguel, Alexandre Nascimento, Graeme Sherriff, Michael Lomas PhD, Reinhard A. Klenke, Elena Maggi, DarkSky, LightingEurope, and many others!
In order to fully understand how light pollution affects our world, we need to know how much of it is in which places. Divergent results from different measurement methods present some tension, but recent research suggests a way forward.

📢 Today, LightingEurope publishes a position paper calling on EU policymakers to introduce a harmonised set of rules for regulating Artificial Light at Night (ALAN).
ALAN plays a crucial role in our daily lives, and well-designed installations using quality products and control systems are fundamental to creating suitable outdoor environments. When designing any lighting application, the effect on the natural environment, including fauna and flora, must be considered, as well as the effects of obtrusive lighting, sky glow, and light nuisance. We need to consider the balance between human needs and environmental concerns in a consistent and effective set of rules.
💡 When creating the specifications for a new lighting system, sufficient consideration should be given to the purpose of the lighting system to be installed, so that:
🔹 All light should have a clear purpose. 🔹 Light is directed only to where it’s needed. 🔹 Light is not brighter than necessary. 🔹 Light is adapted to suit the task activities or turned off when not required.

How many day time butterflies can you name? How many nocturnal moths? Did you know that lions are mainly nocturnal? Our knowledge about #biodiversity is biased towards daytime. However, protection of nighttime habitats especially against increasing #lightpollution is urgently needed. The strategy of conservation umbrellas for nocturnal biodiversity can be a solution to increase awareness.

Similar to one of the authors of this blog post, I got attracted to this same crowd mapping / crowd sourcing project by accident. It was only then, that I started to see light with other eyes for the first time. I started reading about that bulky term 'Lichtverschmutzung' and found my self really quick in the will to start fighting for natural nights. On a kickoff meeting in the city center of Fulda (at that time shortly before awarded as Germany's first DarkSky Community), I met interested people who were eager to help count and catalogue light sources. That night, even a TV team of BR - Bayerischer Rundfunk joined us when we were walking through the nightly city of Fulda, recording us as we counted and logged into the #Nachtlichter app all the lights we could identify. These were public street lights, door bells, shop windows, ads, architectural lighting, exit signs, ...
A lot has changed for me since then - I started a LinkedIn profile, to raise awareness at a place were light means business and found many fellow activists but even more important many people from the lighting industry who are well aware of the problems light poses to health, biodiversity and the night sky and push for ways that standards are set and met to serve light only when it's needed and where it's needed. I'm also baffled every time, when I see how many people are following my profile, which is exclusively focusing on the topic of light pollution and its effects. By today - 1573 people. I am very thankful for your interest and for encouraging me to continue my journey - even though at times I am tired and fed up, seeing light orgies all around, and to say it with Eckart von Hirschhausen's words 'It's hard to save the world on a voluntary basis when others are destroying it for a living.'
How many lights are on when the world sleeps? This latest study shines new light—literally—on the scale and sources of urban illumination in Germany.
Using the Nachtlichter app, citizen scientists classified 234,044 light sources across 22 km², revealing powerful insights into the artificial nightscape.
💡 Key findings: • Space-based radiance data can now be translated into installed lights per km²—a huge step forward in understanding real-world lighting infrastructure. • In German city centers, aesthetic and advertising lights outnumber street lights—a surprising driver of urban brightness. • An estimated 78 ± 3 million light sources remain lit at midnight across Germany, pointing to significant potential for light pollution reduction.
This dataset doesn’t just support research—it gives policymakers a concrete basis for smarter, more sustainable nighttime lighting.
Proud of the collaborative effort, and especially grateful to the fello citizen scientists who made this possible!
