In a striking effort to combat light pollution, officials in Wallonia, Belgium, have initiated a groundbreaking project aimed at removing 75 streetlights in a bid to restore natural darkness and protect local wildlife. This radical approach, set against the backdrop of Belgium’s status as one of Europe’s most light-polluted countries, brings to light the ongoing tension between community safety and environmental conservation.
A Step into Darkness
Nestled in the picturesque countryside near the village of Mazée, the familiar glow of street lamps is set to dim as part of a transformative initiative. Local resident André Detournay, who has walked these paths for decades, expresses his concerns about safety. “Having lights here is logical. It makes me feel safe while I walk my dog,” he states, reflecting the apprehension many residents feel about losing their familiar forms of illumination.
Belgium’s nighttime landscape is often compared to a festive display, with its cities glowing brightly from space. However, the stark reality is that this artificial light obscures the beauty of the night sky and disrupts the natural behaviours of various species. Research has increasingly highlighted the detrimental effects of light pollution on wildlife, particularly on insects, birds, and amphibians, whose life cycles rely on natural darkness.
The Project’s Origins
The concept to turn off unnecessary streetlights originated in 2021 when a public administrator identified that about 6% of the 8,000 streetlights in the Entre-Sambre-et-Meuse national park were deemed unnecessary. These lights were often positioned over 50 metres from any building and near protected areas vital for nature. The national park has allocated €308,000 for this initiative, treating the restoration of nighttime darkness as critical as re-establishing habitats like ponds or woodlands.
Nicolas Goethals, the project leader, acknowledges the delicate balance between ecological conservation and community safety. “We cannot say to an old lady we want to prioritise bats over you,” he emphasises, illustrating the complexities of public sentiment surrounding the initiative.
Community Concerns
Despite the environmental rationale, not all residents are on board with the plan. Detournay’s scepticism reflects a broader concern among locals who equate street lighting with personal safety. “You would have to prove it significantly increased biodiversity here to persuade me otherwise,” he argues. Similarly, Jacques Monty, a long-time municipal worker, voices his apprehension about the implications of reduced lighting on community safety. “It could be good, but we need to ensure it doesn’t compromise the safety of people.”
Public perception remains a significant barrier. While studies in England and Wales suggest that reduced street lighting does not correlate with increased crime rates or road accidents, the subjective feeling of safety remains paramount for many residents. Goethals has organised community discussions and night walks to facilitate dialogue about the project and its potential benefits.
A Broader Movement
The initiative in Wallonia is part of a growing global movement to address light pollution. Countries like France have already implemented measures to turn off public lighting during the night to conserve energy and promote biodiversity. With approximately 80% of the world’s population now living under artificially lit skies, the need for action is urgent.
In a bid to enhance biodiversity, the national park is also retrofitting old electricity pylons to provide nesting sites for white storks, a project that has garnered widespread community support. The installation of these nests is a tangible symbol of how human infrastructure can be repurposed to benefit wildlife.
Why it Matters
As Belgium embarks on this pioneering project to reduce light pollution, it serves as a reminder of the pressing need to reevaluate our relationship with artificial light. While the safety of residents is undeniably important, this initiative highlights the urgent call for a balanced approach to urban planning that prioritises both human and environmental health. The outcomes of this project could set a precedent for similar initiatives across Europe, potentially leading to a renaissance of the natural night sky and a revitalisation of local ecosystems.
