This comprehensive review delves into the multifaceted impacts of quarrying on local communities and the environment, highlighting challenges such as habitat destruction, air, noise and water pollution, environmental degradation, and socioeconomic disparities. Furthermore, it accesses current sustainable quarrying practices and innovative technologies to mitigate these impacts and improve efficiency. To address these challenges, this paper also emphasizes the importance of implementing robust policies and regulations governing quarrying activities in Nigeria. Through analysis of real-world examples, case studies, and existing literature, this review uncovers promising solutions that can enhance quarrying operations' sustainability and environmental performance in Nigeria and worldwide. This paper unveils that, while quarrying is an important industry in Nigeria, it is critical to ensure it is carried out sustainably and responsibly. This can be achieved through improved regulations, strengthening sustainable quarrying practices, conducting thorough environmental impact assessments, establishing buffer zones around quarries, enforcing stricter pollution control measures, stakeholder engagement, and adoption of new technologies such as advanced blasting techniques, dust suppression technologies, automation and robotics machinery, water recycling, and treatment systems, waste recycling management, and reforestation and restoration techniques. It is evident that there are gaps and inconsistencies in Nigeria's policy and regulatory framework, and there is a lack of research on the effective implementation of sustainable practices and new technologies. Therefore, further research is recommended on areas such as the lasting impact of sustainable practices, the potential of new technologies, and the enhancement of policy and regulatory frameworks to improve the sustainability and efficiency of quarrying operations in Nigeria.

With over 100 gully sites in the state, only about 30 have received measures of control but are still not fully under control. Observations have shown clearly that the underlying geology exerts major control over the development of gully erosion in the study area. Progressive gullies in certain areas of Anambra State are caused by various factors, including topography, soil and water pH, lithology type, deforestation, hydrogeology, and geotechnical rock properties. This erosion activity has resulted in the loss of productive lands, water pollution, sedimentation of waterways, and the loss of lives and properties almost every year. However, several government agencies have attempted to manage it using concrete structures, stabilization work such as planting bamboo and cashew trees to increase water intake, and pipe structures to channel the water directly to nearby surfa...

Traditional geophysical methods of pore pressure prediction and reservoir optimization require extensive manual effort and may not fully utilize available data. However, in order to surmount these constraints, deep learning has revolutionized these procedures by engaging in intricate pattern recognition, feature extraction, and predictive modelling. Deep learning models such as Artificial neural network, convolution neural network, Pore-net, FCN, DeepLab V3 +, LSTM, and BP can capture complex patterns those traditional methods might miss. Despite a lack of recorded information in wells, deep learning has significantly reduce uncertainty in pore pressure prediction when information is insufficient. In pore pressure prediction and reservoir optimization, deep learning models can analyse a vast amount of seismic, well log, and geological data to accurately predict pore pressure distribution in subsurface formations and can assist in making informed decisions about production strategies. This helps maximize hydrocarbon recovery, minimize operational costs, and extend the productive life of the reservoir, with better-informed choices, reduced uncertainties, and optimized hydrocarbon recovery from subsurface reservoirs, geoscientists and reservoir engineers can make confident decisions that positively impact the industry. Despite ongoing obstacles such as scarcity of data in developing countries and the complexity of predicting unconventional formations, it is indisputable that utilizing deep learning offers significant advantages. Further research and integration of deep learning with other technologies is recommended in order to facilitate the creation of more efficient approaches for predicting pore pressure and optimizing reservoirs.

However, several government agencies have attempted to manage it using concrete structures, stabilization work such as planting bamboo and cashew trees to increase water intake, and pipe structures to channel the water directly to nearby surface waters through the construction of check dams, embankments, and retention ponds to control the flow of water and sediments. Despite these control efforts, several challenges persist in effectively managing gully erosion in Anambra State. Majority of the concrete structures used to control these gullies have collapsed, leading to the incessant spreading of the site. Inadequate funding, failure of engineering structures, flooding, the geologic setting of the area, limited technical expertise, population growth, urbanisation, a lack of public awareness, and a lack of proper coordination among stakeholders hinder the implementation of comprehensive erosion control measures. It is recommended that concrete drainage channels should not only be used in controlling these gullies but also be integrated with other measures to yield a positive result.
