Improved Air Quality; The Fortuitous Value of Kampala's COVID-19 Lockdown

Top story
Before the lockdown which came with restrictions on the number of activities including traffic, commercial and other pollution generating activities, Kampala’s air quality was already six times worse than global standards mainly caused by dust from unpaved roads, fumes from cars and open burning of waste.

Pollution levels have plummeted in Kampala over the last two months, resulting in an improvement in air quality. 

According to previous air quality indexes, Kampala had a high concentration of tinny air particles small enough to invade even the smallest airways, and the air quality was six times higher than World Health Organization acceptable standards. The pollutants in Kampala are mostly caused by dust from unpaved roads, fumes from cars and open burning of waste.  

But as the country was locked down to contain the spread of coronavirus disease, there was a reduction in the number of vehicles, on the otherwise busy roads in the city, as well as other pollutants which suddenly reduced emissions especially in the central business district. 

Boney Sensi, an official from Advocates for Public Spaces who has been at the forefront of fighting for greener spaces and creating awareness on air quality took us through the streets of Kampala, on a mission to understand the change which could be an eye-opener on the overriding contribution of road transport to urban air pollution.  

The team, armed with a wearable, portable air quality monitor called Atmo Tube Pro went to the streets to measure air quality in selected areas of the city, among them, the Old Taxi Park, Luwum Street, Nakasero market, hardware city area, and Nasser road. Sensi shares that he had moved to the same places with his gadget before the lockdown whose sensors alerted him to vacate the place, due to the poor air quality. This time around, the air pollutant concentrations had greatly reduced and the sensors

remained in the normal range.

Cue out...better air quality.”//  

The Air Quality Index scale runs from 0 to 500. The higher the scale value, the greater the level of air pollution, and the greater the health concern. For example, a value of 50 or below represents good air quality, while over 300 is hazardous air quality. However, the gadget used in Kampala was designed to covert the scale in terms of percentages. 

On average, most of the areas in Kampala had their air quality at 75 per cent. Sensi says that this is too far good given the fact that before the lockdown air quality in the said areas stood at as low as 40 per cent and to someplace like Nasser road it could as low as 30 per cent.  

But, around hardware city, the air quality was still far below, with a reading at 39 per cent. Being in the place is evident that the air here is very poor filled with fumes from trucks ferrying produce and building materials.

Similar observations have been made by AirQo, a research initiative from Makerere University. The project leader Prof. Engineer Bainomugisha notes that their preliminary validation with historical comparisons for the same days of 2019 confirms the drop in pollution levels of about 40 per cent of the daily mean from the two weeks leading to the lockdown, and about 51 per cent reduction for the same days in 2019.

Cue out...to sixty per cent.”// 

Prof Bainomugisha adds that the general slow-down of pollution generating activities from traffic to industry in the current circumstances could have had a strong immediate impact. to him, the situation indicates that there is a possibility of achieving better air quality in the city.

Exposure to poor air quality is one of the leading causes of death globally, greater than smoking or war. The World Health Organization (WHO) says that air pollution is poisoning millions of children, stunting their brains and affecting their health in more ways than was previously suspected.

The threat to human health comes from exposure to near-invisible toxins that are present in polluted air as fine particles. The pollutants penetrate deep into the lungs and bloodstream and cause a range of diseases, which include narrowing blood vessels which could result in a heart attack, chest pain, stroke, or other respiratory diseases such as asthma, chronic bronchitis, lung cancer, and pneumonia. It estimates that over 85 people die in Uganda every day due to causes related to air pollution.


Unfortunately, people working in the polluted areas like Kampala city are not aware that they are breathing to death. Eddie Lutaaya, a city dweller found at the Nakasero market, told our reporter that air quality is not one of their worries because, to him, Africans are immune to such things.

Dr Tom Okurut, the National Environment Management Authority Executive Director, says that they are coming up with the standard of air quality for Kampala and the country. Okurut adds that other interventions to ensure that Kampala has cleaner air even after the lockdown are being discussed with stakeholders including but not limited to Kampala Capital City Authority.    

//Cue in; “We are concluding...

Cue out...here and there.”//  

Dr Okurut further argues that some of the interventions that could lead to greener air like putting up a the better mass transport system, paving streets and putting up a non-motorized transport system in addition to creating green spaces in the city have been partially implemented.
