14:30-16:00 | The past, present and future of public lighting of Montpellier Mediterranean Metropolis

After an introductory presentation on the development of lighting in Montpellier, this session will focus on the lighting assets that the Metropolis manages on a day-to-day basis, the choices it has made to date, and its future prospects. The Lighting Plan outlines the strategy that has been developed and how it will be implemented over the next few years, with a view to considering the many issues surrounding lighting in relation to society and the environment.

Come and discover why “a new night is beginning” in Montpellier.

  • Planning sustainable lighting for biodiversity and societySarah Potin and Léa Tardieu, La Telescop / INRAE

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 International Dark Sky Reserve and neighboring metropolisesRichard Scherrer, Territorial delegate and Project manager, Parc National des Cévennes

The International Dark Sky Reserve was set up in 2018, at the initiative of the Cévennes 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.

09:00-09:45 | Opening & Keynote

  • Illuminating darkness: Unveiling the ultimate light show by reclaiming the nightRuskin 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.

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-beingVirginie Gabel, Founder and CEO of Clock&me; Board Member of Good Light Group
  • What’s behind light pollution, and can we do anything about it? – Christopher Kyba, Post-doctoral researcher at GFZ-Potsdam

11:00-11:15 | Coffee break

11:15-12:30 | Summary and testimonies of the LUCI Light Pollution Working Group

12:30-14:00 | Lunch & Networking

14:15-15:40 | Open Conference Sessions (2 tracks)

The LUCI Open Conference Sessions are the place where LUCI members showcase their cities’ lighting strategies, projects and other initiatives. A Q&A follows each track of presentations.

Applications are open to LUCI city members here until 1 March 2024.

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 format options.

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

The workshop will be lead 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)

The games will be guided by Damien Guiraudie, Michaël Gerber and Céline Latu.

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 lead by Nicolas Houel.

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.
