Prof. Ilemobayo Oguntimehin of Olusegun Agagu University of Science and Technology, Okitipupa, has called for systemic environmental reforms in Nigeria to tackle pollution and mitigate the impact of climate change.
Oguntimehin made the call on Thursday while delivering a public lecture organised by the College of Science and Computing, Wellspring University, Benin.
The guest lecturer, who is also the Director of the Centre for Research, Innovation, and Development (CRID) at Olusegun Agagu University of Science and Technology, Okitipupa, warned that Nigeria faces severe environmental degradation unless urgent measures are taken.
He noted that climate change is exacerbating flooding, biodiversity loss, and respiratory diseases in the country.
“Our air, water, and soil are poisoned daily. The consequences will be dire.
“Nigeria’s development depends on balancing economic growth with environmental protection,” he said, citing Lagos’ rising air pollution and the desertification in the North.
Oguntimehin, a renowned expert in Chemistry, condemned indiscriminate waste disposal, gas flaring, and open burning, highlighting their detrimental effects on air quality and public health.
“We must act now before pollution kills more people,” he warned.
He praised Japan’s hygiene culture, emphasising its role in disease prevention.
“Simple habits like handwashing and waste separation can significantly improve public health. We need stronger policies and real commitment,” he noted.
While acknowledging the Ogoni cleanup as an example of environmental restoration, he stressed the need for stricter enforcement of environmental laws.
He urged individuals to adopt sustainable lifestyles by using energy-efficient appliances, recycling, and avoiding indiscriminate pesticide use.
According to him, small actions can drive significant change across the country.
He advocated for immediate policy shifts, including strengthened environmental regulations, increased funding, and stricter enforcement of anti-pollution laws.
Oguntimehin also challenged the private sector to embrace a circular economy, where resources are used efficiently, waste is minimised, and products are designed to be recycled, reused, or biodegradable.
“Businesses must reduce waste, invest in green technologies, and prioritise sustainability,” he said.
In his remarks, Prof. Isaac Ajayi, Vice-Chancellor of Wellspring University, said the lecture served as a platform to share knowledge with the public.
Ajayi explained that the university was mandated to contribute to society through initiatives such as public lectures.
“This is an opportunity for us to disseminate knowledge, this time through a public lecture.
“It is specifically organised for everyone to attend, learn, and benefit,” he said.
Earlier, Prof. Dipo Komolafe, Dean of the College of Science and Computing at Wellspring University, said the lecture was part of efforts to enhance the university’s reputation through public engagement.
According to him, such events help to showcase research output, provide solutions to societal challenges, and demonstrate social responsibility.
“Public lectures are an effective way to highlight an institution’s academic excellence, leadership, and commitment to social impact.
“We believe that bringing together experts and enthusiasts for lecture series can foster a deeper understanding of the complex issues shaping the world,” Komolafe said.
