Lockdown in South Africa 2020: Unintended Consequences on Street Litter

The COVID-19 pandemic brought about unprecedented global measures, including national lockdowns and home quarantines. One of the lesser-discussed consequences of these lockdowns is the impact on street litter. In South Africa, where a nationwide lockdown was enforced in March 2020, researchers seized the opportunity to investigate how restrictions on human activity affect street litter.

During the strict lockdown period, our team recorded a significant decrease in street litter loads, with an average reduction of three times compared to pre-lockdown levels. The most common types of litter found were convenience foods and beverages (29% by number, 34% by mass) and tobacco products (33% by number, 3% by mass). Interestingly, the ban on the sale of tobacco products during the lockdown did not lead to a significant reduction in cigarette butts and associated packaging.

The lockdown also led to an increase in air quality due to reduced air pollution. This phenomenon, known as the 'anthropause,' offered a unique opportunity to study the impact of human activity on the environment. While this period was marked by numerous challenges, including solid waste management issues and the exacerbation of recycling and re-use initiatives, it also highlighted the potential benefits of reduced human activity.

The findings suggest that there is a clear link between human activity levels and littering. As the lockdown continued, compliance with regulations decreased, leading to an increase in litter. The gradual nature of this increase indicates that individuals were not immediately adapting to new habits, which may have contributed to the persistence of littering behaviors.

This study provides valuable insights into the unintended consequences of national lockdowns on street litter. As governments and policymakers continue to navigate the challenges posed by the COVID-19 pandemic, it is essential to consider the broader environmental implications of these measures. By doing so, we can work towards more sustainable solutions that balance public health concerns with environmental protection.

In conclusion, the lockdown in South Africa 2020 provided a unique opportunity to assess how restrictions on human activity affect street litter. The findings highlight the need for continued research into the complex relationships between human behavior, waste generation, and environmental impact. By understanding these dynamics, we can work towards a more sustainable future that prioritizes both public health and environmental protection.
