14:30 – 16:00: Projects and cooperations with Montpellier Metropolitan Metropolis with roundtable Q&A

by Sarah Potin & Léa Tardieu

Artificial light at night has various adverse effects on the environment, human health, energy consumption, and astronomical observations, which are now well-documented. It is therefore a pressing necessity to implement measures that significantly reduce light pollution. However, striking the right balance between preserving darkness for conservation purposes and meeting human needs for lights at night, poses a significant challenge for stakeholders in urban settings.

We propose a spatial analysis that enables to find the best adjustments for biodiversity and societal needs at the scale of each individual light point. By using satellite imagery and ecological modelling, we identify nocturnal ecological networks for several species, while surveying helps us gauge residents’ acceptability to different measures regarding public lighting.

We undertake this analysis within the Montpellier Metropolitan Area and provide spatialized recommendations to decision-makers for effective and socially acceptable mitigation measures into its lighting plan.

The LUNNE project, funded by the ANR (Agence Nationale de la Recherche, FR), addresses several scientific challenges associated with the reduction of ALAN (Artificial Light at Night). 1) A more appropriate quantification of the impact of ALAN reduction strategies on ecosystems, through the development of new indicators at different spatial scales; 2) A better knowledge and quantification of the impact of these strategies on people (mobility, safety, nightlife); 3) A better understanding of the obstacles and levers to the acceptability of these urban lighting policies. In this context, the reduction of illuminance levels has been investigated in a pedestrian area in Montpellier, taking into account socio-demographics variables (age, gender, familiarity). For that purpose, a survey was conducted based on the state of the art of lighting quality criteria. The first results will be discussed, together with application perspectives for collectivities such as Montpellier.

The International Dark Sky Reserve was set up in 2018, at the initiative of the CĂ©vennes National Park, after obtaining this label awarded by the International Dark Sky Association. This label has made it possible to initiate a dynamic at several levels in the territory in partnership with energy unions and municipalities or urban areas managing lighting. The actions carried out firstly made it possible to renovate the public lighting system to limit light pollution and therefore the financial impact for the municipalities and the ecological impact for biodiversity. Secondly, actions were carried out on the astro-tourism aspect or raising awareness about the night and astronomy. More broadly, work is underway with towns and cities close to the International Dark Sky Reserve, including Montpellier, to limit the impact of light pollution in these metropolises, and to collaborate with public and private stakeholders.

Presentations are followed by a moderated group discussion and Q&A with the audience.

17:30 – 18:00: Networking
18:00 – 19:30: Free time

Friday 25 April 2024

đź“ŤVenue: HĂ´tel de Ville Montpellier (1 Pl. Georges FrĂŞche, 34000 Montpellier)

08:30 – 09:00: Registrations & Coffee
09:00 – 09:45: Opening & Keynote

  • Ruskin Hartley, CEO of DarkSky International

In 1994, Los Angeles experienced a massive earthquake that led to a significant blackout, revealing the Milky Way to many for the first time in years due to reduced light pollution. This blackout highlighted how urban brightness has obscured the stars, a problem that has only worsened, affecting ecosystems, wasting energy, and impacting health. Thirty years on, the challenge of mitigating light pollution is more crucial than ever. This talk discusses the detrimental effects of excessive artificial light and the importance of preserving the night sky. It proposes that with modern lighting technology and thoughtful design, we can enjoy well-lit cities without sacrificing our view of the universe. The discussion emphasises the potential for cities to spearhead the dark sky movement, outlining actionable steps towards reducing light pollution and enhancing the appreciation for natural darkness, thereby reconnecting future generations with the stars.

Followed by a moderated Q&A.

09:45 – 11:00: LUCI Talks

This session includes short curated inspirational talks featuring perspectives from the lighting community.

  • Shedding light on human health: Addressing light pollution’s impact on biological rhythms and well-being

by Virginie Gabel

Light is the human body’s most important “time giver”. If the natural light/dark cycle is disturbed (i.e. by light pollution at night), problems will emerge such as desynchrony between internal rhythms, sleep disruption, and suppression of melatonin secretion at night. These effects have been reported to underly several diseases. More recently, diseases such as breast cancer were also linked to light pollution. But not all types of lights have the same impact. In this talk, you will discover how light regulates the human body, what type of light is involved in those changes, the consequences of the use of “wrong light” on health and some inputs on what could be improved in cities.

  • What’s behind light pollution, and can we do anything about it?

by Christopher Kyba

During the fall of 2021 and 2023, citizen scientists in the Nachtlichter project counted and classified over 400,000 individual light sources in Germany and other countries. Their data represents a complete lighting inventory for a total area of over 20 square kilometers, in contexts ranging from urban centers to rural areas. This talk will present some preliminary results from the project, shedding light on the frequency of different lighting types (e.g. signs, illuminated shop windows, streetlights) and their temporal properties. It will then reflect on what the results mean for efforts to control light pollution. The talk will conclude with an evidence-based criticism of selected existing norms and regulations, and ideas for how to better balance the lighting needs of humans with the darkness needs of humans and nature.

  • EU-funded research on light pollution

by Nicola Robinson

Highlights from the recent Future Brief on Light Pollution (produced as part of the EU’s Science for Environment Policy initiative) – multi-scale transdisciplinary approaches to protect the environment from artificial light at night; monitoring ALAN remotely; emerging research issues and gaps.  Broader EU policy context on light pollution; past and present EU-funded research on light pollution; future opportunities for EU research and project funding under Horizon Europe and other programmes.

Followed by a moderated joint Q&A.

11:00 – 12:00: Open Mic: City changemakers

Moderated by Jasmine van der Pol & Elisa Hillgen

Over the last years, many cities, lighting designers and researchers have been working on projects and initiatives to protect the nighttime environment – and each of us have started the change in our own way. In this open microphone discussion, the city change-makers who took part in the Light Pollution Working Group will unveil their latest strategies and actions with the common goal to make a difference and inspire others to tackle and prevent light pollution.

12:00 – 12:10: Digital journey of public lighting in Flanders

by Jean-Pierre Hollevoet, System Operator, Fluvius

15:40 – 16:00: Coffee break
16:00 – 18:00: Workshops
For an interactive finale to the conference, participants can choose between the three workshop options.

1. Role play – Transforming Montpellier’s Mosson district with public lighting (French with translation) [FULL]

📍 Venue: Salle du Conseil

The workshop will be led by Lionel Bessières, Philippe Clavel and Aurélie Cosyn.

Become someone else and take part in a fictitious public meeting to rethink the lighting in a district of Montpellier! Roleplay during a simulated “public meeting” and respond to a presentation about the impacts of public lighting and first intentions for transforming the Mosson district as your persona of the local population (e.g. a local elderly/retired person, an active sports association member, a young professional etc.). How would they react? What would be their feedback? Come and tell us!

Note: Observers are also welcome if you are not comfortable with roleplaying.

2. Board game – “Switch me off if you can” (French or English) [FULL]

📍 Venue: Coffee area behind the Salle du Conseil HDV

The games will be guided by Damien Guiraudie, Bruno Paternot and Michaël Gerber.

As part of its lighting master plan, Montpellier Métropole created a board game to inform and raise awareness among the elected representatives of the 31 communes in the metropolis about the diversity of problems and issues surrounding public lighting, with a view to combating light pollution. The board game “Switch me off if you can” is a fun way of exploring how decisions can be made in terms of public lighting strategy. “Switch me off if you can” was designed by a company specialised in professional games and produced in France, in very small numbers, by an institute adapted for people with disabilities.

Please specify in the registration form which language you wish to play the game in.

Note: Each game takes about 1 hour.

 

3. Narrative writing – Noctines, new nocturnal narratives (English)

The workshop will be led by Nicolas Houel, Founder, L’Observatoire de la nuit.

📍 Venue: Room PMF in HDV (next to Salle du Conseil)

 

The fabric and uses of the nocturnal city are built around stories that are centuries old. Some real, some imaginary, some lived, some heard. Stories shaped by awe and wonder, fear and upheaval. At a time of changing lighting conditions, Noctines is an invitation to collaborate in writing the nocturnal narratives of generations to come. Narratives that reflect the territories and their inhabitants, where lighting is centered on uses, where light and darkness are balanced, and where fears are, at last, defused. In this workshop, Nicolas Houel invites participants to write such narratives and imagine together the city at night of tomorrow. To wrap up the session, innovative tools such as AI and digital twins will be used to show how the balance between research, sociology and digital can help in the design of the nocturnal ambiances for the next generations.

18:00 – 20:00: Free time
