Ugandans are finding creative solutions to the growing challenges of urbanisation.  Urban farms in Kampala, Uganda, make the most of their limited space. 

When Martin Agaba realised his urban farm had run out of space, he decided the solution was not to expand outwards but upwards.

“We realised we had to use the roof,” he says. Of all the innovations that have galvanised people in his district in the Ugandan capital Kampala to grow their own food, these vertical box plantations remain his favourite.

Kwagala farm, located on half an acre of land, is the brainchild of Diana Nambatya, a professor in public health, who began growing vegetables to save money on food in 2010.

After receiving two cows as a dowry, she decided to use their dung to generate biogas for her home. Her burgeoning urban farm soon attracted the attention of the neighbours, and in 2012 she started training women at a small demonstration centre.
