Every year, the rising levels of pollution continue to endanger human life and the environment. The adverse effects of pollution are becoming increasingly evident, particularly in urban areas, where respiratory illnesses, cardiovascular problems, and weakened immune systems are on the rise among children and the elderly. Delhi, for example, frequently experiences hazardous air quality during the winter months, largely due to vehicular emissions, industrial activities, and crop residue burning. This often leads to public health emergencies, forcing schools to close and restricting outdoor activities. Addressing this environmental crisis has become a top priority for researchers and policymakers alike.
In response to this pressing issue, scientists from the Indian Agricultural Research Institute (IARI), Pusa Campus, under the Division of Plant Science and Environmental Development, conducted an in-depth study on the role of trees in mitigating air pollution. Their research focused on identifying tree species that are most effective in absorbing and neutralizing harmful air pollutants. Among the species studied—peepal, neem, tamarind, ficus, banyan, fig, and ashoka—it was found that peepal and banyan trees are particularly efficient in reducing pollution levels.
This study, published in the Indian Journal of Agri-Horticulture, emphasized the importance of the Air Pollution Tolerance Index (APTI) in determining a tree’s ability to combat pollution. The APTI evaluates various biological properties of tree leaves, such as chlorophyll content, ascorbic acid levels, pH value, and relative water content. These factors collectively determine the extent to which a tree can absorb pollutants like particulate matter, nitrogen oxides, and sulfur dioxide. The banyan and peepal trees emerged as the most effective species, owing to their dense foliage and ability to thrive in polluted environments.
The significance of these findings lies in their practical application. Urban planners, environmentalists, and policymakers can prioritize the plantation of banyan and peepal trees in highly polluted areas, such as industrial zones, highways, and urban centers. These trees not only reduce air pollution but also provide additional environmental benefits, such as cooling the urban heat island effect, improving biodiversity, and enhancing soil quality.
Furthermore, the research highlights the need for community participation in afforestation efforts. By promoting awareness about the environmental and health benefits of native trees, individuals and organizations can contribute to combating air pollution. This includes integrating tree plantation drives with urban development projects, creating green belts around cities, and protecting existing tree cover from deforestation and urbanization.
In conclusion, the study underscores the critical role that banyan and peepal trees play in improving air quality and mitigating the harmful impacts of pollution. By incorporating these trees into urban and rural landscapes, we can take significant steps toward creating a cleaner, healthier environment for future generations.
