Grassy embankments, road reserves and roundabouts do far more than make a city look pleasant. They cool the air, soak up rain and shelter life, if we keep them clean and protected.
Stand at any busy junction in Kampala at the end of a long dry spell and you feel it before you see it: the heat coming up off the tarmac, the dust in the air, the glare off iron roofs. Now look for the places where it is a little cooler. Almost always, there is something green nearby, a line of trees, a grassy bank, a planted roundabout.
We tend to treat these patches of green as decoration. They are not. They are working parts of the city, doing jobs that concrete and drains cannot do nearly as well.
What a patch of grass actually does
Plants cool the air around them by shading the ground and releasing water vapour. Soil under grass and trees soaks up rain instead of letting it race down the road, which means less flooding downstream. Roots hold slopes together, so embankments do not wash away in the first heavy storm. And small green spaces give birds, bees, butterflies and other creatures somewhere to feed and nest in the middle of the city.
There is a human side too. People who have somewhere green to sit, walk or simply look at are calmer and healthier. In a fast-growing city where open land is disappearing quickly, that is not a luxury.
A green space that is not cared for is only a gap waiting to be built on or dumped in.
Why they are under pressure
Green spaces in cities are shared, and shared spaces are easy to neglect. Drainage channels on grassy slopes slowly fill with plastic and other litter. Livestock graze on road reserves and wear the cover thin, leaving bare soil that the next rain carries away. Construction eats into open land one plot at a time, and each loss looks small.
The result is a city that gets hotter, floods faster and has less and less room for nature. None of it is anyone's deliberate choice. It happens when nobody is clearly responsible.
What neighbourhoods can do
The good news is that green spaces respond quickly to care. Residents and youth groups can keep drainage channels and slopes clear of waste and report dumping to local leaders. Neighbours can agree on where animals may graze and where they may not, so that the grass has time to recover. Native trees and grasses, which suit our soils and rains, can be planted on bare ground. And communities can ask, loudly and early, what will replace any green space that is cleared for development.
At CEBCO we work with residents, schools and local leaders to do exactly this, because a greener city is a cooler, safer and healthier one for everyone who lives in it. If there is a green space in your neighbourhood that needs looking after, we would like to hear about it.
