Cultivating shrubs in urban areas can help reduce air pollution by up to 30%, according to a study led by researchers at the University of Surrey. The study found that shrubs absorb and filter pollutants including nitrogen dioxide and ozone through their leaves and bark, and also trap particulate matter such as dust, soot and pollen. Shrubs most effective for pollution reduction included privet, holly and boxwood. Shrubs offer a sustainable and more cost-effective solution to air pollution mitigation than artificial measures such as filtration systems and protective masks, the researchers said.
New Study Finds Shrub Cultivation Can Reduce Air Pollution
A new study conducted by researchers at the University of Surrey has found that cultivating shrubs in urban areas can help reduce air pollution. According to the study, shrubs can absorb and filter air pollutants, improve air quality, and provide other environmental benefits.
The study is a welcome addition to the growing body of research exploring the impact of nature-based solutions on air pollution. As cities continue to grow and air pollution becomes a global challenge, the potential of nature-based solutions to mitigate the effects of pollution is increasingly being recognized.
In this article, we’ll explore the findings of the study, its implications, and the potential benefits of shrub cultivation as a nature-based solution to air pollution.

Shrub Cultivation and Air Pollution
Air pollution is a major environmental and public health issue, especially in urban areas. According to the World Health Organization (WHO), air pollution contributes to around seven million premature deaths each year.
Shrubs are often overlooked in urban planning and landscaping, but they can play an important role in reducing air pollution. The University of Surrey study investigated the potential of shrubs to absorb and filter air pollutants in urban environments.
The study found that planting shrubs in urban areas can help reduce air pollution by up to 30%. The researchers measured the impact of shrubs on a range of pollutants, including nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3).
How Shrubs Absorb and Filter Air Pollutants
Shrubs can absorb air pollutants through their leaves and bark, and filter them through their root systems. The leaves of shrubs can also trap airborne particles, such as dust, pollen, and soot.
The researchers found that the most effective shrubs for absorbing air pollutants are those with densely-packed leaves, such as privet, holly, and boxwood. These shrubs can provide a natural barrier against air pollution, creating a healthier environment for people and wildlife.
Benefits of Shrub Cultivation
Shrub cultivation can provide a range of environmental and social benefits. Apart from reducing air pollution, shrubs can also help combat climate change by sequestering carbon dioxide (CO2) from the atmosphere.
In addition, shrubs can:
– Absorb and store water, reducing the risk of flooding and erosion
– Provide habitats for wildlife, including birds, insects, and mammals
– Enhance the aesthetic value of urban areas, making them more attractive and welcoming to residents and visitors
Shrub cultivation is also a cost-effective and sustainable solution to air pollution, compared to artificial measures such as air filtration systems or anti-pollution masks.
Implications of the Study
The study has important implications for urban planners, policymakers, and communities. It highlights the potential of nature-based solutions to address environmental and public health issues, such as air pollution.
The findings of the study can inform urban planning and design, encouraging the integration of shrubs and other green infrastructure into urban landscapes. This can also help promote a more sustainable and resilient urban environment, as shrubs and other plants can help mitigate the effects of climate change, such as urban heat islands.
The study also underscores the importance of public participation and community involvement in environmental management. Shrubs can be planted in public parks, schoolyards, street medians, and other locations where they can benefit local communities.
The University of Surrey study has demonstrated the potential of shrubs to reduce air pollution in urban areas. By absorbing and filtering pollutants, shrubs can provide a natural and sustainable solution to a growing environmental and public health challenge.
Shrub cultivation can also provide a range of other benefits, including carbon sequestration, water management, biodiversity, and aesthetic value. Urban planners, policymakers, and communities can benefit from integrating shrubs and other green infrastructure into urban landscapes, promoting a healthier, more resilient, and more sustainable urban environment.
Q: Which shrubs are most effective at reducing air pollution?
