A Cameroonian geoscientist, Prof. Felix Toteu, has called for global recognition of geodiversity, saying it remains underrepresented in international heritage frameworks in spite of its critical role in sustaining life.
Toteu made the call on Saturday in Abuja, while delivering a guest lecture in honour of a renowned Nigerian geologist, Prof. Omar Rahaman, as part of activities marking his 80th birthday anniversary.
The lecture, titled “Geodiversity: The Foundation of Our Heritage,” was held during the event tagged “Season of Rahaman 5.0”, organised by the Nigerian Association of Petroleum Explorationists (NAPE) in collaboration with the Petroleum Technology Development Fund (PTDF).
Toteu said that of the six criteria for Natural Heritage recognition, only one directly relates to geology, highlighting the limited global attention given to geodiversity.
He explained that biodiversity refers to the variety of living organisms, including genes, species and ecosystems, while geodiversity encompasses geological elements and processes such as rocks, minerals, fossils, soils and landscapes.
According to him, geodiversity forms the foundation for biodiversity and human existence, stressing the need for stronger policy and institutional support for its conservation.
The geoscientist also noted ongoing efforts to promote geological heritage.
He added that there was a growing push to move from the identification of geosites by the International Union of Geological Sciences (IUGS) to broader international recognition.
“Achieving international recognition for geosites is essential to ensure their protection and promote their value to humanity,” he said.
Toteu further expressed concern over the environmental and health impacts of mining, calling for more responsible and sustainable resource exploitation.
Quoting Rahaman, he said sustainable development in mining required commitment to continuous environmental and socio-economic improvement throughout the life cycle of a mine.
He said the principle remained vital for balancing resource extraction with environmental protection and community wellbeing.
In their remarks, some eminent Nigerians paid tributes to Rahaman, describing him as a resilient scholar, mentor and nation-builder.
Dr Kehinde Ladipo, Chairman of the Season of Rahaman Committee, congratulated the celebrant and commended his contributions to national development.
Also, Mrs Kikelomo Adeola, Deputy Comptroller-General of Customs in charge of Finance, Administration and Technical Services, described Rahaman as an icon in African geology.
Adeola said his mentorship had impacted generations, adding that many professionals across sectors continue to benefit from his guidance.
“I am a customs officer today, still applying what he taught us.
“If you have benefited from his mentorship, you will stand out anywhere in the world,” she said.
Similarly, Assistant Inspector-General of Police, Dr Nkechi Eze, described Rahaman as a man who supported people from all walks of life.
The event featured presentation of awards, gifts and the decoration of the celebrant with a commemorative lapel in recognition of his contributions to geology and national development. (NAN)(www.nannews.ng)
