The lecture will be a 2.30 PM

Measuring the quality of the night sky is necessary to assess light pollution and to evaluate its trends. These derive from a combination of existing and new lighting installations, and the applications of mitigation actions to reduce the amount of luminous flux escaping the primary areas where lighting is needed (and thus generating glare and skyglow), and containing increasing levels of blue light due to the diffusion of new generation lighting. Such measures are especially important in relation to protected areas, where night sky quality measurements by digital cameras have become a routine procedure. However, these observations lack the wavelength dependence of sky radiance; therefore, we have started a spectral sky quality survey parallel with the all-sky radiance measurements. To interpret the measurements, we also performed Monte Carlo simulations with the dominant light sources in the neighborhood of the measurement locations. We studied the effect of the tendencies of different atmospheric conditions for some reference cases with typical cloud and aerosol profiles.  The structure of the aerosol layers has a significant impact on the night sky radiance distribution, and it is neglected in most of the recent light pollution modelling. I will present our first results obtained at the Zselic Starry Sky Park, in the context of a now fifteen-year-old program for the protection and promotion of the night sky in various nature reserves in Hungary.

The visit to Fondazione Mach is part of a tour in Italy with the BuioMetria Partecipativa project, active since 2008 in the interdisciplinary protection and promotion of the night sky.

Zoltán Kolláth, professor of astrophysics at the Savaria University Center, Eötvös Loránd University, Szombathely, Hungary between 24 and 29 July. Prof. Kolláth is one of the highest international authorities in the field of light pollution studies, as well as in the promotion of the night sky as a resource. He was the creator of one of the first international star parks in Europe, the Zselic landscape protection area, and has for many years been a driving force in protecting night skies in Hungary, with the recognition of three parks certified by the International Dark Sky Association.

At the moment, the professor is responsible for a large national project for the development of scientific research on all aspects of light pollution, including the creation of new sustainable lighting systems. As an astrophysicist, he deals with the dynamics of pulsating stars. He is also very active in the dissemination in this sector, for example taking care of the soundtrack of astronomical signals that have been used in exhibitions and musical compositions, including a piece by John Legend.

In the May 16 conference which we organised in Brescia with the BuioMetria Partecipativa project in collaboration with the University’s DICATAM on Interdisciplinary promotion and protection of the night sky, we had a very interesting talk on Italian Regional legislation by Maria d’Amore. Maria has been following this topic for over ten years working at the Emilia-Romagna regional administration, and among other topics she presented a table which we then invited her to share.

The table shows similarities and differences, with respect to various criteria, region by region (for those regions where light pollution regulations are present). This table is an extremely interesting reference both for experts, and for non-experts who may have an idea of how different administrations have been approaching the same topic in the course of time.Regions are listed according to a reverse chronological order related to the year of publication of the most recent law.

The table is updated to June 2019 and is currently maintained in Italian (we may consider translating the table if there are specific requests). For comments or for more information, please write to: bmp@pibinko.org

For centuries we have been used to live with the night sky as a natural part of our landscape, but substantially independent from our activities. With the development of cities and industrial infrastructures, lighting systems came, as a key resource in improving our quality of life, providing security and enabling us to conduct at night activities which were once confined to daytime. However, in parallel, the combination of lighting sources “spilling” light out of their primary target, or with exceedingly high power, started to generate light pollution, actually contaminating the sky.

Light pollution has a series of negative impacts, which were initially perceived only as an issue for astronomers, who had to relocate many of their activities from their observatories, most of which were founded not far from cities, to more pristine areas. Over the past twenty years, however, a significant body of research has strongly improved our understanding of the light pollution issue, exposing also effects on ecology, human health, energy management, road safety, and security. The combination of these effects, in parallel with the fast pace of innovation in the field of lighting technology and a significant unawareness of the negative effects of “too much light” (with the “blue light issue” as a key topic today), makes the light pollution issue simple to appreciate on a basic level, but complex to grasp in its multi-faceted implications: everybody will note the difference in a night sky observed from the centre of a large city or from a rural area, but it is then not so simple to deploy lighting policies balancing the perceptions of different sectors of society in relation to lighting.

Independently of different approaches and perceptions on the use of light at night, there are two elements which cannot be denied, if we look at things from a sustainability viewpoint: the night sky is a common good, so solving light pollution issues requires a participatory approach involving many stakeholders, and lighting sources which are not aimed at lighting areas where illumination is needed should be redesigned, so as to mitigate light pollution effects without reducing the quality of our lives.

In order to showcase different scenarios related to these views the Netherlands Consulate General in Milano has organised an event in Cascina Cuccagna, Milano, on July 16, 2019, from 6.00PM to 10PM, with a talk from 6.30 to 7.30PM, a Q/A moment until 8PM, and then till 10PM an info+engagement desk where citizens, creatives, and experts may become an active part of initiatives related to light pollution monitoring and management.

The event is organised in collaboration with the BuioMetria Partecipativa project, and è is related to the exhibition ‘I See That I See What You Don’t See’ in the Dutch Pavillion at the “Broken Nature” international exhibition in the Milano Triennale. Following a conference on light pollution on May 26, the Consulate General has decided to further elaborate on this topic inviting from The Netherlands one of its main light pollution experts, Wim Schmidt. Wim will showcase various aspects of light pollution issues -and mitigation strategies- as observed in his country, which in Europe is one of the most impacted.

To balance this view, and trigger ideas on how citizens, creatives, and experts should be approaching the protection and promotion of the night sky, Wim will interact with Andrea Giacomelli, an expert coming from a dark sky area in Italy (Southern Tuscany). From the interaction between these two angles, and some pratical activities which will be proposed during the event, participants will be stimulated to look at the sky -and to their lights- with a different awareness, and think twice before they change their next lamp.

About the presenters

Wim schmidt is educated as astronomer and psychologist based in Utrecht. On his 50th birthday he decided to give a turn to his life and started a company providing consulting to municipalities, provinces and enterprises on the mitigation of their lighting impact on the environment. He conducts investigations on the development of night sky quality in the Netherlands and is the chairman of the Dutch organization against light pollution. (http://www.sotto.nl/index-english.html)

Andrea Giacomelli is an MS in environmental engineering and a PhD in hydrology, with 25 years of experience in geographic information systems. In 2007 he started his work on interdisciplinary promotion of assets in the fields of culture, environment, and open innovation. His flagship project is “BuioMetria Partecipativa”, providing since 2008 monitoring, citizen science and outreach initiatives on light pollution and night sky protection. He is based in the Metalliferous Hills of Southern Tuscany. (http://www.pibinko.org)

The BuioMetria Partecipativa (BMP) project has been involved since 2008 in raising awareness on the issue of light pollution, collecting data on this phenomenon through citizen science networks, and promoting “dark sky” areas characterized by the good quality of the night sky. The collection of observations of this kind can be done throughout the year, but the summer season clearly facilitates the participation of non-experts. With BMP we have launched several summer campaigns, usually focused on specific areas. For example, in 2012 with some instruments located in various locations in the Gulf of Follonica, or in 2017 with various measures throughout the Tuscan coast from Versilia to Maremma (plus some of the islands of the Tuscan archipelago).

As a 2019 summer campaign, we will have the honor of hosting a mission to Italy by Zoltán Kolláth, professor of astrophysics at the Savaria University Center, Eötvös Loránd University, Szombathely, Hungary between 24 and 29 July. Prof. Kolláth is one of the highest international authorities in the field of light pollution studies, as well as in the promotion of the night sky as a resource. He was the creator of one of the first international star parks in Europe, the Zselic landscape protection area, and has for many years been a driving force in protecting night skies in Hungary, with the recognition of three parks certified by the International Dark Sky Association.

At the moment, the professor is responsible for a large national project for the development of scientific research on all aspects of light pollution, including the creation of new sustainable lighting systems. As an astrophysicist, he deals with the dynamics of pulsating stars. He is also very active in the dissemination in this sector, for example taking care of the soundtrack of astronomical signals that have been used in exhibitions and musical compositions, including a piece by John Legend.

The mission in Tuscany stems from a relationship established by the BMP with Prof. Kolláth in 2013 and will lead the scientist to visit some sites in Southern Tuscany. This region in Italy is one of the areas with the best quality of the night sky, given that Italy stands out as a country with not so good conditions for light pollution, compared to other states with similar development conditions, as shown by recent studies.
During the mission, the professor will give some outreach presentations on the topics he has studied for over twenty years and will conduct a series of activities to detect and measure the quality of the night sky with high-level scientific instruments. The header image of this article shows an example of an all-sky immage acquired by the professor on the island of Capraia, during the first international symposium on protection and promotion of the night sky in Italy. These measurement will consolidate and expand the observations made by Professor Kolláth in this area in 2015, when he was part of a shorter campaign organised by BuioMetria Partecipativa and the National Research Council from Florence in the context of a European project, with activities in the Farma Valley and in the Tuscan capital.

The actual program of presentations and observation sites in Tuscany will be announced in early July.

After the mission in Tuscany, prof. Kolláth will hold a further event in Trentino, at the Edmund Mach Foundation in San Michele all’Adige, also as part of the initiatives promoted by the BuioMetria Participativa, in the framework of interdisciplinarity and relations among different territories which is one of the cornerstones of the BMP project.
