With the increasing population, urban migration, and middle-class, African cities such as Kigali, Rwanda, are facing great challenges.
In Kigali, Rwanda, organic waste is forecast to increase by 63% by 2030 whilst its current recycling rate is only 12%. A lack of infrastructure leads to environmental pollution and social injustices to most inhabitants of the city. The phenomenon is also occurring in other growing cities of the country such as Butare, Muhanga, Ruhengeri, Gisenyi and in neighbouring countries such Tanzania, Democratic Republic of Congo, Burundi, Uganda.
The raise to middle class income leads almost inevitably to an increasing demand for animal protein – pork, chicken, and fish. Rwanda, as a fast emerging economy, faces a 16% annual growth for animal protein. Yet the country cannot fulfill its needs because inter alia the cost of animal feed represents 77% of the total rearing costs of these animals, making animal rearing a challenging activity. Local production is hindered, imports from neighbouring country are forced, and local prices increase. Ultimately, all population have less access to healthy protein.
