Amadora is a Portuguese city located in the district of Lisbon, specifically in the Lisbon metropolitan area. It is situated approximately 8 kilometers northwest of the capital city of Lisbon and covers an area of 23.78 km². According to the latest available data from the National Institute of Statistics, the city has a population of around 175,136 inhabitants.
One of the most remarkable characteristics of Amadora is its vibrant nightlife. The city has a wide range of bars, clubs, and restaurants that attract a considerable number of people, especially during the weekends. This nightlife culture, combined with the city's urbanization process and population growth, has led to an increase in light pollution.
Light pollution is defined as the excessive or misdirected artificial light produced by human activities, which negatively affects the natural environment and human health. The amount of light pollution in Amadora is estimated to be high, especially in the city center and densely populated areas. The light pollution is primarily caused by street lighting, commercial buildings, and advertising.
In Amadora, there are several landmarks that are known for their night lights. One of the most famous is the Cristo Rei statue, located on the top of a hill overlooking the city. This statue is illuminated at night, creating a striking image that can be seen from various parts of the city. The city also has several parks that are illuminated at night, such as the Parque Aventura, which offers outdoor activities and attractions for children and adults.
The habits of the people living in Amadora also contribute to the light pollution. Many residents leave their lights on all night, either for security reasons or out of habit. Additionally, there is a considerable amount of illegal billboards and light signs, which add to the overall light pollution in the city.
Industry in Amadora is mainly focused on commerce and services, with a few industrial zones located on the outskirts of the city. The industrial areas also contribute to the light pollution, as they have large factories and warehouses that require significant amounts of lighting at night.
