The brightness of the night sky and its color depend on the amount, type and location of light pollution sources. The study of the brightness and color of the sky allows light pollution estimation. Monitoring night sky brightness continuously provides data to statistically study its evolution over time. Part of the light pollution comes from traffic, shops and offices. A decrease in human activity is normally associated with darker skies.
This citizen science project aims to monitor the brightness and color of the night sky using photographic cameras to evaluate variations in light pollution that may happen during the exceptional period of self-isolation we are living.
Anybody with a DSLR camera who is interested in the project is welcomed to participate. This light pollution contribution is expected to decrease considerably during the lockdown


This is an Action project, co-creating solutions for bioplastic waste management with vulnerable groups and other community members in Oslo (Norway). It set up a physical composting station for experiments, to raise awareness about bioplastic waste and how to handle it, demystify the science of composting, and narrow the distance between people and their trash.

Dragonflies and pesticides

This is a Conservation project, concerned with the effect of pesticides on dragonfly populations. Water quality has improved quite a lot in the second half of the last century and dragonflies, as aquatic insects, have recovered in this period. However recently numbers have started to decline again. Organiser De Vlinderstichting knows this because hundreds of their volunteers count dragonflies every two weeks on fixed transects. By comparing the number of dragonflies that are counted they can see how different species are doing in different locations, and even some of the least critical species seem to be disappearing from certain parts of the Netherlands.
Even at levels regularly found in ditches, a specific insecticide can have strong negative effects on damselflies. In this project, participants take water samples, and pesticide concentrations are measured in a central laboratory. This allows the project to investigate whether the trends in dragonflies reflect the exposure to pesticides, the extent pesticides are a threat to dragonflies, and which pesticides are most harmful.

In my backyard

This is an Action project, aiming to understand, map, and ultimately reduce the use of pesticides and fertilizers, and encourage sustainable alternative practices in the context of home farming and gardening. Based in the Neiva river mouth area, in the municipality of Esposende, Portugal, it works with a community of home farmers and gardeners. The project generated open data collections on pesticide and fertilizer usage in home production (farming and gardening) and sustainable practices for home farming and gardening.

Loss of the Night

This is an Investigation project, inviting citizen scientists worldwide to measure light pollution by using the human visual system as a light meter. Participants look for specific stars, and report if they can see them from their location through the Loss of the Night App. Measurements can be made wherever the sky is observable, for example in parks or in open spaces. The observations are sent anonymously to the Globe at Night project where they are archived.
The illumination of the night sky increases annually, outshining the stars, indicating energy waste, and disturbing sensitive nocturnal species. Scientists are concerned that light pollution might have a big impact on nocturnal ecosystems, but they have very little information on how skyglow is changing, especially considering the recent transition to LED lighting. This cannot be achieved with current satellites, and in general is difficult to do via remote sensing, because satellites look at the ground, not towards the sky.

Mapping Mobility


Noise Maps

This is a Conservation project that allows citizens to generate and analyse urban sound data, empowering communities to take action to reduce unwanted noise and protect the local sonic heritage. The pilot builds on existing cultural practices of collective documentation of the sound heritage of neighbourhoods (Mapa Sonor). Thanks to project activities citizens will be able to filter unwanted noise out from authentic, locally unique sounds, thus allowing communities to take action to preserve their sonic heritage. NOISE MAPS deploys a combination of tested tech and methods with a novel approach, to empower communities to leverage the power of citizen science to tackle local challenges of global relevance.

Open Soil Atlas


Sonic Kayaks

This is an investigation project, developing a low cost open hardware for gathering and mapping fine-scale marine environmental data, which has not been previously possible to obtain. Data is sonified through an onboard speaker allowing paddlers to seek out areas of interest and gain real time feedback of the data. The existing system includes underwater temperature sensors and a hydrophone for measuring underwater sound, each recording data every second with GPS, time and date. Working with ACTION, two new environmental sensors (turbidity and air quality) were designed and integrated.

Street Spectra

This is an Investigation project, mapping and characterizing public lighting sources. Volunteers use a low cost diffraction grating on top of their smartphones’ camera to take pictures of street lamps and their emission spectra. The resulting images allow classification of the street lamps by comparison with example pictures of well known lighting systems.
The creation of the project was motivated by the global switch to LED street lighting. The project creates a public database which is considered the primary output, and will allow scientists to study the effects of this change of technology onto light pollution. Street Spectra is currently using epicollect5 to gather data, but an ad hoc mobile application is being developed to improve the participants’ experience.

Students, air pollution and DIY sensing

This is an Education project based in Norway, engaging high school students with the design and execution of their own air quality projects, using an off-the-shelf air quality sensor platform. The aim is to create awareness about the sources of air pollution, make the students think of ways to reduce both emission and exposure, and teach them scientific methods.
The project offers a workshop for teachers where they get information about air quality and air pollution sources, measurements and (health) effects, as well as an opportunity to build a sensor themselves and learn how to program it, enabling them to teach it to their students. The students learn about air quality/air pollution and its effects on society, build their sensor packages and program them, carry out their own measurements, and interpret the results. At the end, all students are invited to join a student conference where they present their work on a scientific poster.

Tatort Streetlight

This is an Investigation project, engaging citizen scientists in the protection of the insect fauna from light pollution. Street lighting can greatly affect nocturnal insects by attracting them to the light and depriving them of their habitats. In addition, if the attraction radii of adjacent street lights overlap, this can result in a barrier effect, making it much more difficult for insects to pass an illuminated street. For this reason, a new street lighting design will be developed to minimize the radiation of light onto the insect habitat. The geometry of the light is strictly directed downwards, so that the light only illuminates the sidewalks or streets and objects on it. The new street lighting will be installed in four communities in Germany. Tatort Streetlight observes the occurrence and behavior of insects for two years before and after the conversion from the existing street light to the new design.
The project will collect insects from traps placed at street lights, and invite amateur entomologists to sample and identify insects, to discuss the results, and to develop ideas for sustainable solutions for night time illumination. For school classes, it will provide opportunities to work with insects, learn about the importance of insect diversity for many ecosystems, and learn about technological equipment to measure the impact of night time illumination.



Walk Up Aniene


Water for Future

This is an Action project, focusing on water pollution in and around the city of Cerro de Pasco, Peru. Building on previous work in the region, the team works with local youth and community members to grow scientific monitoring competences and gather data on water quality. Citizen Scientists will gather samples of water from the city’s tap water supply and at important locations at the main watershed of Cerro de Pasco – the San Juan and Tingo river basins. These will then be tested for heavy metals on field using single use kits and also some water samples will be analysed into a national certified laboratory. The team will also establish a Youth Forum for the development of monitoring strategies and to allow for discussion of and action on the results of this citizen science initiative.

WOW Nature

This is an Action project, based in the Po Valley in Northern Italy, which has one of the worst air qualities in Europe. It uses trees to tackle this problem: studies all over the world are demonstrating the ability of trees in capturing pollution particles, but evidence is needed at the local level. The project aims to measure air pollution with innovative sensors within and outside urban forests in order to assess their efficacy as a mitigation measure for air pollution, facilitate their funding and educate and engage with citizens. Citizens will be involved throughout the project, participating in data collection and in co-developing solutions and policies proposals. Project activities will include education and dissemination activities as well.
