Daniel MendozaUSA

Urban Lighting as an Environmental Justice Marker: Observations and Implications

Dr. Daniel Mendoza is a Research Assistant Professor in the Department of Atmospheric Sciences and holds joint appointments as Adjunct Assistant Professor in the Department of Internal Medicine – Pulmonary Division, Visiting Assistant Professor in the Department of City & Metropolitan Planning, and the NEXUS research institute at the University of Utah. Daniel will present an analysis of streetlight differences found within a city – both in temperature as well as power. The implications for social justice are clear: lower-income communities have a proportionately higher number of second and third-shift workers and active transportation (e.g., public transit, biking, or walking) and are therefore more exposed to improper and excessive lighting. We will follow the rationale of the study and discuss a direct and quantifiable impact (vehicular crashes) as well as ancillary repercussions.

Abhishek Pawse & Deep AnandIndia

Sailing Through a Change, Sailing to a Change

Abhishek is a passionate astrophotographer and visual astronomer who knows the value of dark skies. He successfully convinced his local authorities to dim the street lights in his city to reduce light pollution. Deep is the founder/president of the Save Our Stars initiative working to spread awareness and educate the general public about the problem of light pollution. He believes in following ingenious and unconventional methods for outreach and education. Their presentation will include the journey, efforts, and obstacles faced by both the speakers along with the work done by them for dark sky advocacy in India. It’ll be a step-to-step overview on how through outreach and awareness followed by approaching the local government and working on bigger projects with the government, they commenced the establishment of a dark sky community in India. Even though we work individually, both fields are deeply connected and rely upon each other for proper outputs.

2021 Engagement Workshops

Dark City Walkswith Landon BannisterIntermediate

Sometimes when it comes to selling the issues of light pollution, sometimes it is a case of seeing is believing. This workshop is aimed at sharing some of the successes and mistakes that we’ve learned from running dark city walks over the last 4 years. We’ll cover how to structure a dark city walk, as well as the type of learning outcomes you can find and how best to present them to your audience.

The Stargazer as Storytellerwith Mary Stewart AdamsIntermediate

From the civilization-forming influence of the stars evidenced in ancient cultures to the dramatic shift in humanity’s relationship to the celestial world dating from the 16th century’s scientific revolution, we arrive in the 21st century, where light pollution diminishes views of the sky for most of the world’s population. In this session, Star Lore Historian Mary Stewart Adams will share how to make use of humanity’s rich cultural arts to inspire advocacy, both in relation to our natural environments and particularly in relation to the night sky. Once upon a time, every star had a name, and in every name was a story. What consequence in contemporary human culture, and for the Earth, that we are being cut off from this source of inspiration?

Tips and Tricks for International Dark Sky Place Applicationswith Ashley WilsonIntermediate

Nothing quite embodies the dark-sky movement as one of IDA’s prestigious International Dark Sky Places (IDSP), but starting a nomination from scratch is no small feat. In this workshop, Ashley Wilson, IDA’s own Director of Conservation, will lead an engaging conversation to provide tips and tricks on how to find resources, support, and insight on how you can successfully nominate and lead your own Dark Sky Place application.

Discovering Stargazing Locations with the Meet Star Gazers Mobile Appwith Sujay PatilBeginner

Amongst amateur astronomy circles, it is a well known that the best telescope is not the biggest one but the one that you use most often. It is my personal conviction that the same reasoning applies to stargazing locations. The best stargazing location is not necessarily the darkest one but the one that you can access and visit most often. In this workshop, I propose to take our participants through the process of characterizing any stargazing location. As a result, participants will get to know the Meet Star Gazers mobile app and understand its usage to find locations for stargazing.

A Retrofit Gone Rightwith Tim BrothersAdvanced

Many of us have been frustrated with the all-to-common bad streetlight retrofit from HPS to LED technology. The results are often the same: high glare, excessive brightness, increased quantity of blue light and disappointed residents. We also find that many of these failed projects correlate with a lack of public engagement. Here we will examine how inclusion of public opinion and how pivoting from activist to adviser resulted in the most nighttime-friendly streetlights in the northeastern United States. After summarizing the approach, we will discuss your city’s future lighting project and how to get a seat at the table.

Lighting for Safety and CPTEDwith Art HushenIntermediate

With increased emphasis on the night sky and lighting, CPTED (Crime Prevention Through Environmental Design) strategies are often overlooked as part of the process for lighting design. Issues with light pollution, glare, and light trespass are not thoroughly addressed as part of lighting and safety. Under the CPTED model, lighting is used for the illumination human activity. Where this activity takes place and the type of lighting provided are critical when it comes to improving the overall feeling of safety. As people use the space and take ownership, there are fewer opportunities for crime.

Letter to Your Neighborwith Adam KreuzerBeginner

 Adam will share information, including his letters, about his current successful two-year campaign to persuade his neighbors to be more dark sky friendly. As a result of his letters and interactions with his neighbors, Adam’s neighbors have responded favorably. Not only are his neighbors more dark sky friendly, but they are also more aware of how artificial light at night affects our wildlife friends, including our nocturnal pollinators.

Educate People About the Dark Skies, We Must.with Dajana BjelajacBeginner

If you are a beginner in the dark sky movement or you’re feeling alone in your surroundings where too few people care about the night sky, this workshop will provide you with the tools and ideas for fun and engaging events where you can turn people to the dark side! And then, once you gather a group of enthusiasts such as yourself, you have to keep them inspired and teach them how to be leaders themselves. As Master Yoda said “Smaller in number are we, but larger in mind”, so even if you start with a small group, you can teach them about the importance of the dark skies, and big changes will definitely be on their way.

Finding Values in the Dark: Exploring Dark Skies Through Art and Designwith Taylor StoneIntermediate

How can we draw attention to the value(s) of darkness, especially for those who may not have regular access to dark skies? One powerful tool is art and design, which can provide a lens through which to see nighttime lighting from a new perspective. This workshop will discuss and analyze projects that reflect upon the profound effects of artificial illumination and the state of the world after dark. We will discuss the different values, and value conflicts brought to light via the work of different artists and photographers, and how such projects could contribute to advocacy work and policymaking.
