    The New Elsan Evaluation of Environmental Impact (EEEI) Method for the Assessment of Environmental Impacts of Industrial Activities in Rural Communities
    (European Organization for Nuclear Research, 2025-11-04) Mansaray, Hassan Elsan
    The Elsan Evaluation of Environmental Impact (EEEI) method represents a transformative approach to assessing environmental impacts in rural communities affected by industrial activities, particularly mining. This study focuses on three communities in Tankoro Chiefdom, Sierra Leone—Kanniya, Koakoyima, and Sahr Quee Town—to evaluate the environmental, social, and economic consequences of mining operations. The EEEI method integrates community perceptions with advanced statistical analyses, offering a unique combination of inclusivity and rigour. Using multivariate statistical techniques, the study identifies significant environmental degradation, including deforestation and water contamination, as well as socio-economic disruptions, such as displacement and loss of traditional livelihoods. Positive impacts, such as job creation and infrastructure development, were observed but were limited in scope and overshadowed by the broader negative consequences. Unlike traditional approaches like the Rapid Impact Assessment Matrix (RIAM), which rely on qualitative scoring, the EEEI method employs a standardised numerical framework, allowing for objective, replicable, and scalable evaluations. Results demonstrate significant main effects for individual predictors and highlight a moderate interaction effect between the Kanniya and Sahr Quee Town communities. The study concludes that the EEEI method is a robust tool for environmental assessments, capable of revealing critical insights into the interconnected dynamics of industrial impacts. Recommendations are provided for further testing and refinement of the EEEI model across diverse contexts, emphasising its potential for broader application in environmental governance and policymaking.

    Assessing the Socio-Economic and Environmental Impact of Koidu Holdings on Local Communities in Tankoro Chiefdom, Kono District, Sierra Leone - Using the Rapid Impact Assessment Matrix Method
    (2024-05-25) Mansaray, Hassan Elsan
    The study used the RIAM technique to evaluate environmental sustainability using an environmental impact assessment through nine sessions of focus group discussions in the affected mining communities. The system's methodology involves assigning scores to impact component issues based on predetermined criteria, which are then transferred into arrangements that indicate the extent of positive or negative effects. The RIAM analysis reveals that kimberlite diamond mining has predominant negative environmental impacts across all three communities, A, B, and C. However, certain social and economic components reflected positive changes. Nevertheless, the positive impacts on those three communities are just about the same. From the total scores summary for the three communities, it is obvious that the kimberlite mining in the affected communities have negative effects than the positive effects. Based on these findings, recommendations were made for improvement.
