Students from the College of Agricultural and Environmental Sciences (CAES), Makerere University have come up with a user friendly and affordable technology dubbed, KeBELA BIOSENSOR to test farm produce for pesticide residues. Since access to organic agricultural market demands that produce has to be certified by an accredited certification body, KeBELA Technology is seeking to ease and quicken the process by producing an affordable and user-friendly technology, which can be employed by the certification bodies to cut down the cost of certification and hence ease access to the global organic market by farmers.
KeBELA is a handheld device that is designed to detect and quantify levels of pesticide residues in agricultural products. This innovation is led by Ambrose Kamya, a fourth year BSc. Agriculture student mentored by Prof. Fred Kabi.
This device is linked to a mobile application that automatically receives the test results using Bluetooth and centralizes all the information thereby making farmers visible in the market space as well as aiding government planning and increasing traceability for export.
The use of the mobile application linked to the gadget helps in identifying the farmer physical location by GPS coordinates. The gadget also indicates the farmers’ products tested in real time.
“We are currently working with National Organic Agriculture Movement Uganda (NOGAMU) to create a data bank of all organic farmers who can be traced by their organic produce and physical location.
The data bank will be updated by the information collected using the gadget and a highway will be used to deliver the updates to the central location.
The exporters and importers of organic products will then be able to access or trace the farmers using the data bank to which NOGAMU will have the key,” Ambrose Kamya the student explained.
This will make it easy for the importers and exporters to access farmers without necessarily visiting their farm physically.
“We have applied for a national patent to Uganda Registration Services bureau (URSB) and have got a file number. However, due to the high regional demand for the technology within the organic sector, we are applying to ARIPO for a regional patent but financial constraints have deterred the process, Kamya further said.
Proposed design of the KeBELA BIOSENSOR
Kamya was one of the CAES students that exhibited during 26th Source of the Nile Agricultural Show and Trade Fair held from 13th to 22nd July, 2018. The Minister of Agriculture, Animal Industry and Fisheries Hon. Vincent Bamulangaki Ssempijja hailed Kamya for the technology and expressed interest to visit the CAES and interact with the students about the future of KeBELA BIOSENSOR.
Why KeBELA BIOSENSOR?
The certification process for organic farmers is expensive. This is partly because the current technologies used for testing farm produce for pesticide residues are not only sophisticated but time consuming. This has scared away many potential organic farmers from seeking certification services even when they follow ecological farming principles.
Such farmers who would be candidates for certification recruitment end up selling their produce to the conventional market thus losing out on premium prices. Therefore, despite the increasing demand for organic agricultural produce both domestically and globally, many Ugandan farmers fail to exploit this great global market opportunity worth 80billion US dollars.
According to NOGAMU, the situation can be improved if user-friendly and affordable technologies for testing pesticide residues can be developed. Since access to organic agricultural market demands that produce has to be certified by an accredited certification body, KeBELA Technology is seeking to ease and quicken the process by producing an affordable and user-friendly technology, which can be employed by the certification bodies to cut down the cost of certification and hence ease access to the global organic market by farmers.

On March 21, 2026, I felt a strong urge to reconnect with a close colleague and passionate leader, Owekitinisa Sylas Ruhweza Atwooki. We had not spoken since I moved to the United States to pursue my dream of becoming a journalist. The following day, I learned that he had been quietly undergoing treatment in and out of the hospital. True to his character, he had chosen to keep his condition private. I was shocked and saddened, wishing I had known earlier so I could offer support.
At first, reports from family and friends were encouraging. He had been diagnosed with malaria and low blood platelet counts and was receiving treatment. Respecting his wish for confidentiality, members of the Mastercard Foundation Scholars and Alumni community at Makerere University rallied discreetly around him.

However, on April 29, his condition worsened. He was transferred between medical facilities and underwent extensive tests, including a biopsy, as doctors searched for answers. Sadly, on May 29, Sylas passed away.
His death sparked an extraordinary outpouring of love and solidarity. Friends, colleagues, and former scholars mobilised to support his family, settle medical expenses, organise virtual vigils, and plan a dignified farewell. Hundreds gathered at St. Augustine Chapel to pay their respects. Within three days, the Mastercard Foundation Scholars and Alumni community raised approximately UGX 11 million, a testament to Sylas’ impact on countless lives.

In the days that followed, I found myself wrestling with difficult questions. In a world where we spend so much time following people online, are we paying enough attention to those quietly transforming lives around us? Why do we invest so much emotional energy in distant personalities while overlooking the people God has placed right in front of us?
Sylas lived with humility and served with grace. His death left more than 1,500 Mastercard Foundation scholars and alumni grieving, alongside many others around the world who knew him. Yet his passing also exposed a contradiction in modern life.
We live in an age of unprecedented connectivity. Uganda has millions of internet users and WhatsApp subscribers, while globally, people spend hours each day on social media. We have more tools than ever to stay connected, yet many of us are becoming increasingly disconnected from the people who matter most.

Sylas resisted this trend. Through mentorship, service, and community-building, he remained deeply present in others’ lives. While many people retreat into individual pursuits, he consistently chose connection.
This challenge is especially relevant for Mastercard Foundation scholars and alumni. Every year, young Africans leave home to pursue education and professional opportunities abroad. Distance, time zones, visa restrictions, and rising travel costs make it difficult to maintain relationships and remain actively involved in the communities that helped shape us.
For Sylas, the answer was simple: show up. Celebrate others. Offer support. Stay connected.

He never allowed geographical or personal barriers to become excuses for disengagement. Even while facing his own struggles, he invested in others. He embodied the values the Mastercard Foundation seeks to cultivate—ethical leadership, service, and community empowerment.
Sylas did not wait for a perfect platform to create change. He simply served where he was. He helped build bridges between education, culture, and professional development while remaining grounded in his values. He dreamed of creating a stronger alumni ecosystem and brought both passion and compassion to every initiative he touched.
Since his passing, social media has been filled with memories of his infectious smile and unwavering commitment to others. Those tributes reveal an important truth: people gave generously because Sylas had first given himself generously to them. People from different backgrounds, generations, and communities showed up because he had spent his life showing up for them. His legacy now challenges all of us.

The greatest tribute we can offer is not simply to mourn his loss but to continue his work. That means supporting the causes he cared about, helping the children whose education he championed, strengthening alumni networks, and pursuing the dreams we discussed with him.
The tragedy of modern life is not that we follow people online. It is that too often our attention to distant lives comes at the expense of meaningful relationships nearby. Yet strong relationships are as essential to our well-being as physical health.
As Ugandans, we take pride in our faith, culture, and sense of community. We contribute to fundraisers, attend ceremonies, and support family members in times of need. But increasingly, genuine connection is being replaced by passive digital interaction. Families and communities cannot thrive on likes, retweets, and emojis alone.
They require presence—phone calls, visits, conversations, and the willingness to notice when someone is struggling.

Before spending another hour immersed in the lives of strangers online, look around. Call the friend you have not spoken to in years. Check on a family member. Reach out to a colleague who seems withdrawn. Communities are not built by algorithms or celebrities. They are built by ordinary people who choose, day after day, to care for those within their reach.
Uganda needs more people like Sylas. At just 32 years old, he achieved what many spend a lifetime striving for. He served as Minister of Information in the Toro Kingdom and as President of the Mastercard Foundation Scholars Alumni Association in Uganda. More importantly, he dedicated himself to serving others.
While his death is deeply painful, his life remains a powerful example of how we should live. My prayers and condolences go to his family, friends, and the entire Mastercard Foundation Scholars and Alumni community.
Rest in perfect peace, Owek. Sylas Ruhweza Atwooki.
