“A deteriorating urban environment is the enemy of sustainable development. Protecting the environment is not an alternative to economic growth—it is a precondition of efficient, economic development.”

In respect to this United Nations sustainable development goal, the Uganda Christian University (UCU) Faculty of Science and Technology’s Department of Engineering and Environment has a project focused on waste management. With the assistance of a $3,000 grant from UCU Partners through the university’s Institute for Faith, Learning and Service, the department built a prototype of two composters and an incinerator to help conserve the environment while also boosting agriculture and health in a low-income community in Mukono.

“People knew that they had the wastes, and they were concerned about its possible implications, but they did not know how to manage it,” Kenneth Econi Yikii, a teaching assistant and demonstrator at the department, said during an interview, “But from the time we set up that pilot project, there has been very positive response from the community that people want more of it.”

Rodgers Tayebwa, a lecturer at the department, said the project was conceived after an assessment that revealed the need among the community around the university.

“We realized that a lot of solid wastes were being produced but, while the community could use the wastes for boosting their agricultural output, they were being disposed as unwanted materials,” Tayebwa said.

Under the project, 10 students were selected based on a concept writing competition organized by the department. Their concepts were then merged with ideas from their lecturers to generate the designs for two plastic and metallic composters (double-decker composters), and an incinerator. The design came after a series of processes, including mapping the area, a baseline survey, waste characterization and selection of the pilot households.

At least 40 households were selected for the waste characterization process to determine the kinds of wastes most produced in the area. Bio-degradable wastes (dead organisms, kitchen waste, etc.) were found to be the most, followed by plastics.

At least two composters and an incinerator were installed in Basiima Kikooza village, in the outskirts of Mukono town.  This village was chosen after being identified by local authorities as the most vulnerable to the outbreak of hygiene-related diseases such as cholera because of their poor waste management. About 30 households are now benefitting from the project that has not only improved their health, but also their agricultural yield.

The beneficiaries dispose of their bio-degradable wastes (unwanted material that can rot), and continuously turn them from time to time to ensure oxygen circulation, until they are ready for transfer to the second decker that transforms them into organic manure.  From there, they are collected and spread directly into the farmers’ gardens.

According to Yiiki, the bananas and bean crops in the farmers’ gardens look greener. There are no flies gathering around in large numbers to feast on household wastes like food. Plastics and polythene bags, which do not easily decompose, are sorted and either incinerated or sold out to companies that recycle them. This has increased the household income of the members who sort out and sell recyclable items while reducing the potential breeding space for mosquitoes, which transmit malaria.

When the monitoring team last visited the project site in February, the farmers had already collected manure at least twice from each of the composters since their installation in January.

Tayebwa said the involvement of students has been key for their learning, and was also highly appreciated by the community. He said as they continue to monitor the pilot project, they hope that more funds will be availed for the same project in the future so that they are able to reach out and give back to more members of the community surrounding the university.

NOTE: Uganda Christian University (UCU) captured first place among 48 higher education institutions in the 11th Annual Exhibition of the National Council for Higher Education (NCHE) in Uganda in March. Among displays representing UCU and contributing to this honor was the nakati experiment described in this article.

What’s liquid, full of vitamins, green and with a name common to most East Africans?

Nakati juice.

Ummm. Yes, but perhaps it needs another title.  While some Ugandans have fond childhood memories of chewing onnakati as their parents wove a tale of how it would increase their intelligence, most turn up their noses at the green, leafy vegetable’s bitter taste and the remembrance of times when the family could afford little else.

Nakati, which also is known as African eggplant, needs to rise above its bad reputation, according to two Uganda Christian University (UCU) Food Science and Technology students and their teaching assistant. They aim to do just that by using it as the main ingredient in beverage and food recipes that reinforce nutritional value and good taste.

Jovan Kyambadde, teaching assistant, UCU Department of Agricultural and Biological Science, and students Athieno Sheilla and Alexis Ossiya, explain that the nutrition part is that nakati is full of iron and vitamins. Adding sweet-tasting ingredients masks the unpleasant flavor. After dodging raindrops to pluck nakati leaves from their Mukono campus garden and purchasing fruit outside the campus gate on the afternoon of March 6, they chopped, cut and blended the juice, sharing a not-so-secret recipe.

  • Four medium size mangos and one-fourth of a pineapple for flavor, one lemon for increased vitamin C and preservative, one freshly picked bunch of nakati (main ingredient) and honey for sweetener.

Nakati is the main ingredient because it has certain special health benefits such as cancer-fighting compounds, and anti-aging properties, and aids proper bone and brain development. Mangoes and pineapples likewise are rich in vitamins and antioxidants that help to prevent cancer, improve skin complexion and greatly boost immunity.

The taste-testers on this day were five nearby students, who gave mixed reactions about thickness, sweetness and whether they would prefer this no-added-sugar, vegetable and fruit juice over the more common, sugar-added, fruit-only beverages.

“We plan to do more testing with students in the large cafeteria,” Sheilla said. “We think we could make money and help others do it.”

While one end result is making money for the inventors and healthier lifestyles for their customers, this project also is about helping Uganda’s local farmers with their profits, Jovan explained, adding, “Everywhere you look in Uganda, there’s nakati.”

The students prepared the drink using an electric blender. But for locals without electricity and a mechanical mixer, the juice still can be made with added shredding, pounding and hand pressure, using a sieve to filter out the juice.

Under the title “Better Vegetables, Better Lives,” the UCU Department of Agricultural and Biological Science works with a dozen other partners to improve production and use of African indigenous vegetables for greater nutrition and income.  The plan is to not only share nakati products on the university campus, but also to teach local farmers how to do the same.

According to UCU Professor Elizabeth Balyejusa Kizito, changing dietary and lifestyle preference is one main reason that vegetables like nakati and another green leafy vegetable called doodo are being cast aside for less indigenous and less healthy fried chips and samosas. Sub-Saharan children have the highest rates of anemia and malnutrition in the world. UCU is on an action research mission to change that.

Each Wednesday morning, the students and staff of the Department of Agriculture and Biological Sciences at UCU board a bus, and after a 45-minute drive, are dropped off to work with local farmers.

“The farmers have come to regard themselves as university teachers, which they are in that they put our students’ learning in real context,” Jovan said. “At the same time, our students are teaching the farmers what they know about crop rotation, germination, higher yield and marketing.”

Nakati, for example, is going to waste when it could be used for juice, biscuits and other products. In addition to experimentation with nakati beverages, the students are exploring use of the vegetable with g-nuts and other ingredients for snacks.

“When I was a little girl, I was told that eating nakati would make me more intelligent,” Sheilla said. “I know now that’s not true, but using nakati in recipes is pretty smart.”
