To restore the degraded riverbanks of Mathare River, the Green Army team from Baba Dogo Ward and Climate Wax team planted 200 seedlings at Kasabuni on Wednesday, November 27, 2024.
The initiative aims to combat pollution and enhance environmental conservation in areas where air quality remains a serious concern. Recent data from the Air Quality Index (AQI) indicates that parts of Mathare and Ruaraka Sub-County frequently record pollution levels above 150 AQI, which are categorized as unhealthy. Elevated levels of particulate matter (PM2.5) are known to cause respiratory issues.
The Green Army, known for spearheading community service projects, has also led clean-up drives and recycling workshops to promote waste management and reduce litter.
This collaborative tree-planting effort is expected to protect the river from further degradation and improve air quality, offering much-needed relief to the region’s residents and contributing to a healthier, greener environment.
Recent data highlights the worsening air quality in Nairobi, with areas like Mathare, Ruaraka, and Dandora particularly affected. IQAir shows that the PM2.5 concentration in Nairobi is 3.9 times the World Health Organization’s (WHO) recommended annual guideline, reflecting a significant health risk. Nairobi’s Air Quality Index (AQI) recently registered at 70, indicating “Moderate” pollution levels, but sensitive groups are still advised to limit outdoor activities
The UN Environment Programme (UNEP) has flagged air pollution in Nairobi as a major health concern, citing 1,300 premature deaths in 2024 linked to air pollution. The economic cost is also significant, with pollution-related impacts estimated at $220 million this year alone
The main pollutants include PM2.5, PM10, and carbon monoxide (CO), posing risks particularly to children, the elderly, and those with respiratory conditions.
