Prof Joseph Ouma Muga was one of Kenya’s most accomplished scholars, but his career also became entangled in one of the most intriguing political controversies of the Daniel arap Moi era.
Born in Homa Bay, Muga built an impressive academic career before entering politics.
He studied Geography at Makerere University and later pursued postgraduate studies in Australia, earning a doctorate in fluvial geomorphology.
He joined Makerere University as a lecturer in 1966 and later held senior academic positions in East Africa.
His expertise in environmental science eventually brought him close to the political establishment. Muga became associated with the development of environmental studies at Moi University and helped establish its School of Environmental Studies. Homa Bay County records describe him as an influential environmental scholar whose work contributed to the understanding of ozone depletion and climate change.
But it was his entry into politics that would make him a household name beyond academia.
Muga won the newly created Rangwe parliamentary seat in the 1988 General Election on a KANU ticket. His political rise was rapid, and he was appointed an assistant minister in President Moi’s government. His closeness to the centre of power appeared to put him on a promising political trajectory.
Then came the ozone-layer controversy.
In the late 1980s, President Moi attended an international engagement where he delivered a detailed speech on the depletion of the ozone layer. The address reportedly impressed international leaders and left Kenyans surprised by the President's command of a highly technical environmental subject.
During a 2023 National Assembly debate, former Rangwe MP James Nyikal recalled that Kenyans were astonished by Moi’s knowledge of the subject. According to the parliamentary account, Muga later acknowledged that he had written the speech for the President. The revelation, Nyikal said, marked the beginning of the fallout between Muga and Moi.
The story, however, has several versions.
Contemporary and retrospective accounts reported that Muga allegedly boasted that he was the intellectual force behind Moi's celebrated ozone speech. According to an account published by Climate News, the allegation reached Moi amid an intense KANU political environment where rumours and rivalries were common. Muga was also reportedly accused of boasting about his closeness to the President and claiming that Moi had created Rangwe Constituency specifically for him.
Whatever the precise circumstances, Muga's political fortunes changed dramatically.
On May 2, 1989, he was moved during a Cabinet reshuffle to the Ministry of Reclamation of Arid, Semi-Arid and Wastelands. Just nine days later, he was dismissed as an assistant minister. By July, he had lost his parliamentary position. The rapid collapse of his political career fuelled speculation that the ozone-speech controversy had contributed to his downfall.
Importantly, the claim that the speech alone caused his removal remains difficult to establish conclusively.
Parliamentary records confirm the alleged confession and its association with the fallout, while other accounts point to political rivalries and allegations that Muga had been boasting about his influence.
The controversy should therefore be understood as a combination of documented events and competing retrospective accounts.
Muga's political career did not end there. After the introduction of multiparty politics, he returned to Parliament in 1992 on a FORD-Kenya ticket, winning Rangwe with a commanding majority.
Official election records cited by ConstitutionNet show that he secured 31,852 votes, representing 95.41 per cent of valid votes cast.
His second political comeback was short-lived. He lost the Rangwe seat in the 1997 election to Shem Ochuodho, receiving only 1,542 votes against Ochuodho's 26,030. He never returned to Parliament.
Muga's life had another controversial chapter even before his confrontation with Moi. While teaching at Makerere University, he was implicated in a failed 1971 coup plot against President Jomo Kenyatta and was imprisoned.
Homa Bay County later recorded the episode as part of his complicated political history.
Despite the controversies, Muga remained remembered for his extraordinary intellectual ability and environmental scholarship.
He died in September 2018, ending the life of a man whose career moved from academic brilliance and international environmental work to national politics, political controversy and eventual obscurity.
His story remains striking because the very expertise that brought him into the orbit of President Moi became linked to the controversy that helped define his political downfall: a brilliant scholar who reportedly wrote a technically complex speech for a powerful President, only for the authorship of that speech to become part of a political rupture that changed his fortunes forever.
