1.1 Introduction
Geology education refers to the academic discipline and training that focuses on the study of the Earth's structure, processes, and materials, and their application in various fields such as engineering, construction, and environmental management (Breen & Sanders, 2020). It includes both theoretical and practical knowledge aimed at understanding the Earth's composition and its impact on infrastructure projects. Geology education plays a critical role in the development of infrastructure, particularly in regions with complex geotechnical challenges. In Nigeria, rapid urbanization and infrastructure growth have underscored the need for qualified geologists to provide insight into soil stability, land use planning, and the prevention of natural disasters such as flooding and landslides. The role of geology education in infrastructural development is multi-faceted, as it equips professionals with the necessary knowledge to address the geological challenges that impact construction projects.
According to Olojede et al. (2019), a solid foundation in geology ensures that infrastructural projects such as roads, bridges, and buildings are constructed on stable ground, minimizing the risks of future structural failures. Furthermore, geology education facilitates informed decision-making regarding the siting of new infrastructure, considering factors such as mineral resources, seismic activity, and groundwater potential (Sowunmi, 2021). As Nigeria continues to expand its infrastructural capacity, the contribution of geology education in fostering sustainable development and reducing the environmental and economic costs of poorly planned structures becomes ever more apparent.

1.2 Background of Study
The relationship between geology education and infrastructural development in Nigeria has evolved significantly over the decades, shaped by both local challenges and global trends in education and urbanization. Historically, Nigeria's focus on geology as a discipline within higher education institutions can be traced back to the establishment of the first geology departments in the 1940s and 1950s, primarily in institutions like the University of Ibadan and the University of Nigeria, Nsukka (Adebayo, 2017). Early geology education in Nigeria was primarily concerned with mineral exploration and resource management, as the country's economic growth was heavily dependent on its natural resources, such as oil, coal, and solid minerals. This narrow focus, however, meant that the broader implications of geology on infrastructure development, particularly in urban planning and construction, were often overlooked.
As Nigeria's population grew and urban centers expanded, the need for robust infrastructural planning and development became apparent. Challenges such as inadequate roads, poor drainage systems, and building collapses due to unstable soil conditions led to a growing recognition of the importance of geology in infrastructure. In response, the Nigerian government and educational institutions began to integrate more comprehensive geological principles into urban development and engineering curricula (Olajide, 2019). By the 1980s, it became increasingly clear that geological education was crucial for assessing environmental and construction risks, particularly in the face of rapid urbanization, climate change, and resource management issues.
The importance of geology education in infrastructural development has become increasingly evident, especially in countries like Nigeria, where rapid urbanization and infrastructural expansion often occur in the face of numerous geological challenges. Geology, which is the study of the Earth's structure, materials, processes, and history, provides crucial insights for assessing the suitability of land for construction projects. In Nigeria, where infrastructure projects are often hindered by unstable terrain, flooding, and poor soil conditions, geology education equips professionals with the necessary skills to mitigate these risks. According to Adamu et al. (2020), the lack of geological input in the planning and construction of infrastructure has often led to avoidable failures such as building collapses, road damages, and water scarcity issues, especially in areas with unstable soil or flood-prone regions. In response, the Nigerian government and various educational institutions have made strides in strengthening geology programs at universities and technical colleges. This has led to the production of highly skilled geologists who are capable of offering vital support in projects related to road construction, urban planning, and resource management (Olorunfemi, 2018). Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the effect of geology education on infrastructural development.
1.3 Statement of Problems
Investigation revealed that the effect of geology education on infrastructural development in Nigeria is hindered by several challenges that undermine its potential benefits. One significant issue is the insufficient integration of geological expertise in the planning and execution of infrastructure projects. Despite the growing importance of geotechnical and environmental factors in infrastructure development, many projects still proceed without adequate geological assessments, leading to poorly planned roads, buildings, and drainage systems that are prone to failure (Olorunfemi, 2018).
Furthermore, there is an evident gap between the theoretical knowledge imparted in geology education and the practical application of this knowledge in real-world infrastructural projects. The lack of sufficient funding and infrastructure to support advanced geological research and fieldwork also limits the scope and quality of geology education in Nigeria (Olojede et al., 2019). It is against the backdrop that this study seeks to address these problems by investigating the effect of geology education on infrastructural development in Nigeria.
1.4 Aim and Objectives of Study
The aim of the study is to investigate the effect of geology education on infrastructural development in Nigeria. In achieving this aim, the following specific objectives were laid out as follows:
