Light pollution is excessive, poorly directed or unnecessary artificial light at night.
- Wastes energy and money.
- Affects the natural day-night/light-dark cycle under which all species and ecosystems on earth have evolved.
- Endangers night time habitats and disrupts natural rhythms (e.g. circadian and seasonal) of both diurnal and nocturnal species.
- Destroys the natural darkness of nocturnal landscapes and obscures the view of the star-filled sky.
- Disorients insects and other animals, thereby reducing ecosystem services.
- Affects human well-being and health through its association with insomnia, obesity, metabolic disorder and hormonal cancers.
- Potentially decreases safety due to glare.
- Causes annoyance and reduces privacy by obtrusive light.
In this challenge we will explore how we can make sure that light pollution is better understood by all of us, including not only citizens but also public administrations who are in charge of public lighting plans. The list of activities will be released before the Climathon.
The problem posed in this climathon is to reduce the consumption energy, and therefore the emission of CO2, from the systems of lighting, while minimizing the impact of artificial light on environment.
But not only the technological aspect of the solution is important. The awareness of citizens (and administrations) is also key public) when it comes to addressing the problem. For this, it will be studied how citizen science can help a better understanding of problem, while educating in a responsible use of resources. He they will study examples like Cities At Night (http://www.citiesatnights.org
), NightKnights (http://www.nightknights.eu
) and Farolapp (http://farolapp.linkeddata.es
) to later devise new applications that help in this task.
Finally, we will address the problem of data integration due to the heterogeneity of the sources. We will use sensor data from our network of photometers (http://tess-dashboards.stars4all.eu/
), lighting points located in Open Street Map, photographs taken from the Station International Space of the Cities At Night project and notices from of the data portal of the Madrid City Council.
If you can not go to climathon, do not worry, you can participate through our social networks and take a prize:
Have the camera ready these nights and as soon as you see a negative practice take a photo and upload it to your twitter or Facebook with the Hashtag #Déjanosver and tagging Stars4All. The ten most retweeted will be exhibited during the #ClimathonMadrid18 that takes place from October 26th to 27th. The participants will vote for the winning photo. The most original is awarded. You have until October 26 at 4:00 pm to participate.
Find the four points marked on the map, photograph them and upload them to the networks with the hashtag #MadridatNight by geolocating them and tagging Cities at Night and Stars4All. The more you find more opportunities to win our raffle. The game begins on the night of October 26. Stay tuned to our networks! There we will raise the point in the plane of Madrid with light pollution that must be located and photographed.
