In a solemn announcement, the newly appointed Director General of the Tanzania Agriculture Research Institute (TARI), Dr. Thomas Bwana, has expressed deep sorrow over the passing of TARI’s former Director General, Dr. Geoffrey Mkamilo.

Dr. Mkamilo’s death occurred on March 02, 2024, at the Benjamin Mkapa Hospital in Dodoma. Preparations for his funeral are underway, with the schedule to be released by the Ministry of Agriculture.

Dr. Mkamilo’s legacy extends beyond his research, as he was also a distinguished educator in the agricultural sector. His work published/co-published on ResearchGate, with 61 publications, over 18,000 reads, and 1,257 citations, showcases his commitment to spreading knowledge and fostering innovation. Through his educational endeavours, Dr Mkamilo played a crucial role in mentoring the next generation of scientists, ensuring the continuous advancement of agricultural practices and science. For more on his educational impact and research contributions, I recommend visiting his ResearchGate profile.

Dr. Mkamilo’s tenure at TARI was marked by significant contributions to agricultural research and development, making his loss deeply felt across the scientific and agricultural community in Tanzania. The institute is now faced with the task of continuing its vital work in agricultural research under the new leadership of Dr. Bwana, who is committed to advancing the legacy of his predecessor and furthering the institute’s mission.

The entire TARI community has extended its condolences to the family, friends, and colleagues of Dr. Mkamilo during this difficult time. Further details regarding the funeral arrangements will be communicated in due course. The agricultural sector mourns the loss of a distinguished leader whose work has left an indelible mark on Tanzania’s agricultural landscape.

Before he was appointed to lead TARI, Dr. Mkamilo, was the coordinator for Root and Tuber Crops Research in Tanzania, presents on the importance of cassava in Tanzania and the challenges of improving productivity.

He was the Board Chair of ASARECA and, in his role as director general, was a member of the SAGCOT Annual General Meeting. The members of SAGCOT Center Limited comprise the three founding organizations which are the Agriculture Council of Tanzania (ACT), Confederation of Tanzania Industries (CTI), and Tanzania Agricultural Research Institute (TARI).

James Legg, a plant virologist at IITA, last year during the AGRF summit in Dar es Salaam, described him as, “Dr. Geoffrey Mkamilo is the dynamic, hard-working & gracious Director General for the Tanzania Agricultural Research Institute. He has played a key role as a breeder & now Director in transforming cassava value chains through research in Tanzania.”

Dr. Thomas Bwana officially took over from Dr. Mkamilo as the Director General of TARI following a handover ceremony on February 20, 2024, at the TARI headquarters in Makutupora, Dodoma. After the tenure of Dr. Mkamilo came to a close, Dr. Bwana was appointed to this position by the President of the United Republic of Tanzania, Dr. Samia Suluhu Hassan, on February 03, 2024, marking a new chapter in the leadership of the institute.
