An independent initiative making air-quality information more accessible, understandable and actionable for communities in Dar es Salaam through affordable monitoring technology and open data.
Explore Air Quality DataOur Mission
To provide accessible, reliable and locally relevant air-quality information through affordable sensor technology, open data and innovative monitoring approaches, empowering communities, researchers and decision-makers to better understand the air they breathe.
Our Vision
A future where everyone in Dar es Salaam has access to reliable air-quality information, enabling healthier communities, informed decisions and more sustainable urban development.
Air is something we cannot choose not to breathe. Knowing what is in it is the first step towards protecting our health and improving the places we live.
Polluted air is recognised by the World Health Organization as one of the major environmental risks to health. Long-term and short-term exposure can affect the heart and lungs, and children, older people and those with existing conditions are often the most sensitive.
PM2.5 means tiny airborne particles 2.5 micrometres across or smaller — around thirty times thinner than a human hair. They come from sources such as vehicle exhaust, burning of waste and wood, cooking fuels, dust and industry. Because they are so small they can be breathed deep into the lungs, which is why they are one of the most widely monitored pollutants.
Air quality can change from street to street and hour to hour. Measurements collected locally, and shared openly, help people see conditions where they actually live, work and travel — not just a distant estimate.
Consistent monitoring builds an evidence base. It can support research, raise public awareness, help people plan their day and inform discussions about cleaner transport, waste management and urban planning.
We collect particulate matter measurements using affordable stationary and mobile air-quality sensors.
We combine sensor measurements with geographic information to visualize how air quality varies across different locations in Dar es Salaam.
We transform environmental measurements into accessible maps, trends and insights that support public awareness and informed decision-making.
