Prof. Felix Toteu, a Cameroonian geoscientist, has called for greater global recognition of geodiversity, arguing it is underrepresented in international heritage frameworks despite its foundational role in supporting life. He made the appeal on Saturday in Abuja during the Rahaman Lecture, delivered in honour of Nigerian geologist Prof. Omar Rahaman on his 80th birthday. The event, titled "Season of Rahaman 5.0," was organised by the Nigerian Association of Petroleum Explorationists (NAPE) in collaboration with the Petroleum Technology Development Fund (PTDF). Toteu noted that only one of the six criteria for Natural Heritage recognition by UNESCO directly relates to geology, underscoring the imbalance in global conservation priorities. He defined geodiversity as the variety of geological features and processes, including rocks, minerals, fossils, soils and landscapes, which form the basis for biodiversity and human survival. The geoscientist highlighted ongoing efforts by the International Union of Geological Sciences (IUGS) to identify geosites, but stressed the need for broader international recognition. "Achieving international recognition for geosites is essential to ensure their protection and promote their value to humanity," he said. Toteu also raised concerns about the environmental and health impacts of mining, advocating for sustainable resource exploitation. He cited Rahaman's principle that sustainable mining requires continuous environmental and socio-economic improvement throughout a mine's lifecycle. Tributes poured in from dignitaries, including Dr Kehinde Ladipo, Chairman of the Season of Rahaman Committee, and Mrs Kikelomo Adeola, Deputy Comptroller-General of Customs, who credited Rahaman's mentorship for shaping her career. Assistant Inspector-General of Police Dr Nkechi Eze also praised Rahaman for his support across professions. The event included awards, gifts and a commemorative lapel presented to Rahaman.
A geoscientist highlights the global neglect of geodiversity while celebrating a Nigerian geologist whose mentorship has shaped careers in fields far beyond geology, including customs and policing. If geological expertise is foundational to national development, as Rahaman's influence suggests, then its absence from key heritage and policy frameworks undermines long-term planning. The recognition of geosites remains symbolic without institutional backing that matches the scale of their contribution. Yet no commitment to fund or institutionalise such support was announced at the event.
