Light pollution surges in Ahmedabad, raising concerns
Ahmedabad’s nightscape has transformed dramatically over the past decade, but this artificial glow comes with consequences. A recent study by researchers from the Maharaja Sayajirao University of Baroda has revealed that Ahmedabad witnessed a staggering 60% increase in night-time radiance over the past 10 years, with Surat and Vadodara recording 45% and 41% rises, respectively. While city lights create a picturesque skyline, excessive artificial illumination is emerging as a significant environmental and public health concern. Experts warn that prolonged exposure to artificial brightness can disrupt sleep cycles, leading to insomnia and metabolic disorders. Additionally, uncontrolled light pollution is disturbing nocturnal ecosystems, affecting birds, insects, and other wildlife.
Urban sprawl and infrastructure intensify night-time brightness
A closer examination of the study’s findings indicates that the highest radiance levels were observed in Ahmedabad’s western regions and bustling transit zones, such as the airport and railway stations. With rapid urbanisation, expanding road networks, and increased commercial activity, the demand for high-intensity lighting has surged. The study forecasts that night-time brightness will continue to escalate in 2024, with Ahmedabad expected to reach a radiance of 27.8 in November, compared to 13.1 in June. Similarly, Vadodara is projected to record a high of 27.6 in December and a low of 13.9 in June, while Surat will fluctuate between 16.6 in December and 9.8 in June. This intensification of artificial lighting underscores the growing need for smart urban planning that balances development with sustainability.
Environmental impact and sustainability challenges
The impact of excessive artificial lighting extends beyond human health. Researchers highlight that cities worldwide are experiencing a surge in streetlights, with a 2022 study projecting a 15% increase between 2021 and 2027, with 89% utilising LED technology. While LEDs offer energy efficiency, they also contribute to skyglow, obscuring natural darkness and affecting migratory birds and pollinators. Sustainability experts emphasise the need for city administrations to implement policies that regulate unnecessary lighting, promote shielded streetlights, and integrate smart lighting solutions that adjust brightness based on necessity. Responsible urban lighting strategies can mitigate energy wastage, reduce carbon footprints, and preserve the natural night-time environment.
A call for urban rethinking and civic responsibility
The growing light pollution in Gujarat’s cities signals an urgent need for regulatory interventions and urban design modifications. City planners and municipal authorities must rethink illumination strategies to balance human convenience with environmental sustainability. Introducing adaptive lighting systems, limiting excessive street illumination, and redesigning public lighting structures can significantly curb night-time radiance without compromising safety. Moreover, public awareness campaigns can help citizens understand the long-term implications of unchecked artificial lighting. As urban centres expand, addressing light pollution should become a priority, ensuring a future where cities remain vibrant without compromising the well-being of their inhabitants and surrounding ecosystems.
