Environmental Impact Assessments (eia): Analysis Of Transboundary Environmental Impact Assessments For The Development Of A Uniform Teia Model

This dissertation investigates the evolution, processes, and importance of Environmental Impact Assessments (EIAs), focusing on transboundary EIAs and the need for a uniform framework. Originating from the National Environmental Policy Act (NEPA) of 1969 in the U.S., EIAs have become globally adopted instruments for assessing and mitigating environmental impacts of development projects. This work reiterates historical milestones, strengths, and current limitations of EIAs. Research also included a review of environmental regulations from Mexico, such as the General Law on Ecological Equilibrium and Environmental Protection (LGEEPA). Through several case studies requiring the use of transboundary EIAs, where shared resources and concerns were taken into consideration, the dissertation addresses the complexities of the elements needed in a transboundary EIA. A proposed transboundary EIA model, designated as the Chapa T-Model, is presented as a framework seeking to promote a user-friendly model for TEIA writers to follow. The model provides insight into each element required in a TEIA, with guidance and recommendations that emphasize the TEIA's role in protecting the environment, fostering public participation, and enabling informed decision-making. By emphasizing transparency, simplicity, and adaptability to diverse cultural and geographical contexts, the model offers a standardized yet flexible approach to addressing environmental issues in border regions. As global challenges continue to escalate, there is an increasing need for uniform and innovative tools like the proposed Chapa T-Model. This work lays the groundwork for future researchers and policymakers to establish the Chapa T-Model as a fundamental element of international environmental governance, fostering a sustainable future for all.
