Abstract

This research investigates effectiveness of Environmental Impact Assessment as a tool for Sustainable development. The study uses descriptive research design, and it analyses responses from stakeholders to understand the multifaceted roles of EIA in reducing environmental impacts, enhancing stakeholder engagement, protecting ecosystems and biodiversity, improving environmental quality, reducing project risks and liabilities, and promoting sustainable development objectives. The findings reveal that the reduction of environmental impacts, cited by 17.5% of respondents, underscores EIA's fundamental role in mitigating adverse environmental consequences, ensuring sustainable resource use, and reducing costs associated with environmental degradation. The enhancement of stakeholder engagement, acknowledged by 12.5% of respondents, highlights the importance of inclusive processes that involve affected communities, indigenous groups, and environmental organizations, fostering community support and preventing costly conflicts and delays. Furthermore, protection of ecosystems and biodiversity, recognized by 25% of respondents, emerges as a critical aspect of EIA. This emphasis on conservation helps maintain ecological balance and prevents biodiversity loss, thereby preserving essential ecosystem services that support various economic activities. Finally, the promotion of sustainable development objectives underscores EIA's broader impact on aligning projects with sustainability goals, enhancing economic viability, and attracting global support and investment. therefore, it is recommended based on the findings, to maximize the reduction of environmental impacts, regulatory bodies should ensure strict implementation and enforcement of EIA guidelines and mitigation measures and adequate monitoring and compliance checks should be conducted to ensure that projects adhere to the recommended environmental safeguards among others.
