GEO 406: ENVIRONMENTAL IMPACT ASSESSMENT (2 Units)

What is EIA?
Environment Impact Assessment or EIA can be defined as the study to predict the effect of a
proposed activity/project on the environment. A decision-making tool, EIA compares various
alternatives for a project and seeks to identify the one which represents the best combination of
economic and environmental costs and benefits.

EIA systematically examines both beneficial and adverse consequences of the project and ensures
that these effects are considered during project design. It helps to identify possible environmental
effects of the proposed project, proposes measures to mitigate adverse effects and predicts whether
there will be significant adverse environmental effects, even after the mitigation is implemented.
By considering the environmental effects of the project and their mitigation early in the project
planning cycle, environmental assessment has many benefits, such as protection of environment,
optimum utilisation of resources and saving of time and cost of the project.
Properly conducted EIA also lessens conflicts by promoting community participation, informing
decision makers, and helping lay the base for environmentally sound projects. Benefits of
integrating EIA have been observed in all stages of a project, from exploration and planning,
through construction, operations, decommissioning, and beyond site closure.
The main purpose of EIA is to inform decision-makers and the public about the potential
environmental consequences of a proposed action, thereby promoting sustainable development by
identifying ways to minimize negative impacts and maximize benefits.

2. Evolution of EIA
EIA is one of the successful policy innovations of the 20th Century for environmental
conservation. EIA is termed as one of the best policy innovations in the 1900s. The main aim of
EIA is to conserve the environment and bring out the best combination of economic and
environmental costs and benefits.
Today, EIA is a formal process in many countries and is currently practiced in more than 100
countries. EIA as a mandatory regulatory procedure originated in the early 1970s, with the
implementation of the National Environment Policy Act (NEPA) 1969 in the US. A large part of
the initial development took place in a few high-income countries, like Canada, Australia, and
New Zealand (1973-74). However, there were some developing countries as well, which
introduced EIA relatively early - Columbia (1974), Philippines (1978).
To understand the Environmental Impact Assessment evolution and history:

1
 1. The birth of EIA is dated back to the 1970s. In 1969, The USA had brought its first National
Environment Policy Act (NEPA) 1969.
2. The EIA was initially practised by developed nations but slowly it was also introduced in
developing nations including India.
3. Columbia and the Philippines are the earliest examples of developing nations who
introduced EIA in their policies. Columbia brought it in 1974 while the Philippines in 1978.
4. Worldwide, EIA is now practised in more than 100 countries. By the mid-1990s, some 110
countries applied EIA as a major environmental policy.
5. In 1989, EIA was adopted as the major development project by the World Bank.

Environmental Considerations in Project Development

Environmental Impact Assessment (EIA) is a systematic process of identifying the future
consequences of a current or proposed action (IAIA, 1998). An EIA can also be seen as a process
of identifying, predicting and evaluating the likely environmental, socio-economic, cultural and
other impacts of a proposed project or development to define mitigation actions- not only to reduce
negative impacts but also provide positive contributions to the natural environment and well-being.
In the past, planning was based on the concept of economic efficiency; environmental
considerations were not incorporated in the project planning and implementation of development
activities. Various environmental issues such as land degradation, loss of species, pollution, hazard
settlement, etc., were observed consequently. The escalation of environmental problems brought
a fundamental shift in the perception of environment as a crucial factor in sustainable development.

Necessities of Environment Impact Assessment

EIA is carried out in a wide variety of sectors (manufacturing, tourism, industry, mining,
hydropower development) in accordance with the level of impact on human and environmental
health. It plays a significant role in the prediction of the environmental and social impacts of the
project prior to its development. This information is crucial for decision-makers and stakeholders
to make plans accordingly –aiming to enhance the positive impacts and reduce or mitigate the
adverse impacts. It will also reduce the long-term cost of the project and maximize the efficient
use of natural and human resources. Beside this, the ultimate aim of the EIA is to promote
sustainable development by ensuring that development proposals do not undermine critical
resources and ecological functions or the well-being, lifestyle and livelihood of the communities
and people who depend on them.

2
Recognising, the importance of environment management, most countries have embedded EIAs
in their national policy framework (Tools A1), enacted legislation (Tools A2) and prepared
environmental assessment guidelines. Nowadays, EIAs are a prerequisite for many international
financial and multilateral aid agencies such as Asian Development Bank (ADB), World Bank and
Inter-American Development Bank (IADB) to sanction loan for development projects.

Methodology for EIA Implementation

The methods and procedure to conduct EIA differs among countries. However, some criteria,
prescribed by laws or regulations, for deciding whether water use, or water-related projects should
be subject to EIA include:
• The size or scale of the project.
• The sensitivity of the affected area.
• The character or complexity of the likely impacts.
• The basic methodology of EIA consists of following elements major steps (Fig. 1),
• Screening: It is a process followed by the preliminary assessment of the project that helps
to determine whether the project requires and full EIA or not based on significant impacts
that project bears on the environment and people. Screening is conducted by reviewing the
legal and policy definition, threshold criteria and project type and location.
• Scoping and Impact Analysis: Scoping is the crucial as it aims to identify all the potential
environmental impacts and then narrow them down so that the assessment focuses only on
the key issues. This process informs and identify stakeholders and their concerns and issues
through public participation. It also establishes the Terms of References for the EIA study.
• Review and Consultation: This step review the quality of the EIA report taking account
of the public comments. It further determines the sufficiency of the information provided
and identifies any deficiencies to be corrected for decision-making.
• Decision- Making: It is the process where the decision makers take a political choice
between the alternatives, weighting the benefits and cost of the project through the
negotiation, bargaining and trade-offs.
• Follow-up and adaptive management: This step confirm that the condition of project
approval is implemented satisfactorily and verify that impacts are within predicted or
permitted limits. It also ensures that environmental benefits are maximised through good
practice and learn from experiences to improve EIA process and practices.

Strategy of Environmental Impact Assessment (EIA)
The strategy of Environmental Impact Assessment (EIA) encompasses a structured approach to
integrating environmental considerations into the decision-making process for proposed projects.
This strategy is designed to ensure that potential environmental impacts are identified, assessed,
and addressed before project approval. Below are key components and steps involved in the EIA
strategy.
Key Components of EIA Strategy/ Process
The stages of an EIA process will depend upon the requirements of the country or donor. However,
most EIA processes have a common structure and the application of the main stages is a basic
standard of good practice.
The environment impact assessment consists of eight steps with each step equally important in
determining the overall performance of the project. Typically, the EIA process begins with
screening to ensure time and resources are directed at the proposals that matter environmentally
and ends with some form of follow up on the implementation of the decisions and actions taken as
a result of an EIA report. The eight steps of the EIA process are presented in brief below:

i. Screening: First stage of EIA, which determines whether the proposed project, requires an
EIA and if it does, then the level of assessment required.
ii. Scoping: This stage identifies the key issues and impacts that should be further
investigated. This stage also defines the boundary and time limit of the study.
iii. Impact analysis: This stage of EIA identifies and predicts the likely environmental and
social impact of the proposed project and evaluates the significance.
iv. Mitigation: This step in EIA recommends the actions to reduce and avoid the potential
adverse environmental consequences of development activities.
v. Reporting: This stage presents the result of EIA in a form of a report to the decision-
making body and other interested parties.
vi. Review of EIA: It examines the adequacy and effectiveness of the EIA report and provides
the information necessary for decision-making.
vii. Decision-making: It decides whether the project is rejected, approved or needs further
change.
viii. Post monitoring: This stage comes into play once the project is commissioned. It checks
to ensure that the impacts of the project do not exceed the legal standards and
implementation of the mitigation measures are in the manner as described in the EIA report.

 Environmental Impact Statement, Standard, Procedure and Format For Preparation
And Presentation Of Such A Statement

Environmental Impact Statement (EIS): Standards, Procedures, and Format

An Environmental Impact Statement (EIS) is a crucial document required under the National
Environmental Policy Act (NEPA) for federal actions that significantly affect the quality of
the human environment. It provides a detailed analysis of the potential environmental impacts
of proposed projects, alternatives to those projects, and mitigation measures. This document is
essential for informed decision-making and public involvement in environmental governance.
Standards for EIS Preparation
The preparation of an EIS must adhere to specific standards set forth by the Council on
Environmental Quality (CEQ) and relevant federal or state regulations. Key standards include:
i. Clarity and Conciseness: The EIS should be clear and concise, allowing stakeholders to
understand the potential impacts without unnecessary complexity.
ii. Comprehensive Analysis: It must provide a thorough analysis of all significant
environmental impacts, including direct, indirect, and cumulative effects.
iii. Public Participation: The process must ensure opportunities for public involvement
throughout the assessment phases, particularly during scoping and review periods.
Procedures for Preparing an EIS
The EIS preparation process generally follows these key steps:
1. Notice of Intent (NOI):
The lead agency publishes an NOI in the Federal Register to announce that an EIS
will be prepared. This notice invites public participation and comments on the
proposed action.
2. Scoping:
Scoping is a critical step where the agency identifies the range of issues to be
addressed in the EIS. This involves gathering input from stakeholders, including
the public, local governments, and other agencies, to determine significant
environmental concerns and alternatives to be analyzed.
3. Draft EIS (DEIS) Preparation:
The DEIS is prepared based on the scoping results. It includes detailed descriptions
of the proposed action, alternatives considered, affected environment, and potential
environmental consequences.

20
4. Public Review:
The DEIS is circulated for public review and comment for a minimum period
(typically 45 days). During this time, public hearings may be held to gather further
input.
5. Final EIS (FEIS) Preparation:
After reviewing comments on the DEIS, the agency prepares a FEIS that addresses
all substantive comments received. This document may also include additional
analyses or modifications based on feedback.
6. Record of Decision (ROD):
Following the FEIS, the agency issues a ROD that outlines the chosen alternative
and any mitigation measures that will be implemented.
Format for an EIS
The format of an EIS is standardized to ensure consistency and comprehensiveness. According
to CEQ regulations (40 CFR 1502), an EIS should typically include the following components:
1. Cover Sheet: A brief summary that includes project title, lead agency, and contact

preparation and presentation, an EIS serves as a comprehensive tool for informed decision-
making that promotes transparency and public engagement in environmental governance.

Relationship Between EIA with existing settlement level in Nigeria

The relationship between Environmental Impact Assessment (EIA) and existing settlement
levels in Nigeria is crucial for understanding how development projects can be effectively
planned and executed while minimizing adverse impacts on communities. Given Nigeria's
rapid urbanization, significant population growth, and diverse socio-economic conditions, EIA
serves as a vital tool to ensure that development initiatives align with local needs and
environmental sustainability.
1. Urbanization and Settlement Patterns
Nigeria is experiencing rapid urbanization, with an estimated urban population growth rate of
about 4.3% per annum. As of 2018, approximately 50.3% of the population lived in urban
areas, leading to a pressing housing deficit estimated at 17 million units by 2019
This urban growth presents both opportunities and challenges for development projects,
necessitating careful planning through EIA to address potential impacts on existing
settlements.
2. EIA as a Tool for Sustainable Development
EIA provides a structured approach to assess the potential environmental and social impacts
of proposed developments, particularly in densely populated areas. It helps identify:
i. Adverse Impacts: Projects may lead to displacement, loss of livelihoods, or degradation
of local resources. For instance, the Abuja Technology Village project highlighted
community grievances related to inadequate resettlement conditions and loss of farmland,
which are critical for local livelihoods
ii. Beneficial Impacts: EIA also identifies potential benefits such as job creation, improved
infrastructure, and enhanced local services. For example, initiatives aimed at addressing
housing deficits can lead to increased investment and poverty reduction if managed
properly

22
3. Community Engagement and Stakeholder Participation
A fundamental aspect of EIA is public participation, which is essential for understanding the
needs and concerns of existing settlements. Engaging local communities allows for:
i. Incorporation of Local Knowledge: Local residents often possess valuable insights into
the socio-economic dynamics and environmental conditions that may not be evident from
external assessments
ii. Conflict Mitigation: Involving communities in the EIA process can help address historical
grievances related to past projects, such as inadequate compensation or poor living
conditions following resettlement.
This was evident in the Abuja Technology Village project where community skepticism
stemmed from previous experiences with resettlement processes.
4. Regulatory Framework
The EIA process in Nigeria is governed by the EIA Act of 2004, which mandates that all major
developments with potential negative environmental impacts undergo an EIA. This regulatory
framework ensures that:
i. Compliance with Standards: Development projects must adhere to environmental
regulations that protect existing settlements from adverse impacts.
ii. Integration with Urban Planning: EIA processes are increasingly being integrated into
broader urban planning efforts to ensure that new developments complement existing
settlement patterns rather than disrupt them
5. Addressing Socio-Economic Disparities
EIA can also play a role in addressing socio-economic disparities within existing settlements:
i. Equitable Distribution of Benefits: By assessing the socio-economic impacts of projects,
EIA can help ensure that benefits are distributed fairly among different community
segments, including marginalized groups.
ii. Mitigation Strategies: The identification of potential negative impacts allows for the
development of mitigation strategies that can support vulnerable populations affected by
new developments.
Conclusion
The relationship between EIA and existing settlement levels in Nigeria underscores the
importance of integrating environmental assessments into development planning. As
urbanization continues to reshape Nigeria's landscape, effective EIAs will be essential for
ensuring that development projects align with community needs while promoting sustainable
practices. By fostering public participation and addressing socio-economic disparities, EIA can
help create a more equitable framework for managing Nigeria's rapid development amidst its
complex socio-environmental challenges.

 Legislative Background of EIA In Nigeria
The legislative framework for Environmental Impact Assessment (EIA) in Nigeria is primarily
governed by the Environmental Impact Assessment Act No. 86 of 1992. This act establishes
the legal basis for conducting EIA and outlines the procedures and requirements for assessing
the environmental impacts of proposed development projects.
Key Legislation
1. Environmental Impact Assessment Act No. 86 of 1992:
i. This act mandates that all major development projects undergo EIA to evaluate
their potential environmental impacts before approval.
ii. It categorizes projects into two main categories:
a) Category I Projects: Require a full EIA.
b) Category II Projects: May require a partial EIA focusing on mitigation
measures.
iii. The act specifies the minimum content of an EIA and provides guidelines for
conducting assessments, including public participation and stakeholder
engagement.
2. Federal Environmental Protection Agency (FEPA):
i. Established under the EIA Act, FEPA was tasked with overseeing environmental
protection and ensuring compliance with EIA regulations.
ii. It serves as the apex regulatory body for environmental matters in Nigeria,
responsible for issuing Environmental Impact Statements (EIS) based on EIA
reports.
3. National Environmental (Impact Assessment) Regulations:
i. These regulations provide detailed procedural guidelines for implementing the EIA
process, including screening, scoping, and public consultation.
ii. They outline the responsibilities of project proponents and regulatory agencies in
conducting EIAs.
Procedural Framework
The EIA process in Nigeria follows several key stages:
1. Project Proposal:
The proponent submits a project proposal to the relevant authority, indicating the
nature and scope of the project.

24
 2. Screening:
Initial assessment to determine whether an EIA is required based on the project's
potential environmental impacts.
3. Scoping:
Identifying key issues and concerns to be addressed in the EIA, along with
determining the spatial and temporal dimensions of potential impacts.
4. EIA Study:
Conducting detailed assessments of environmental impacts, including baseline
studies and analysis of alternatives.
5. Review Process:
The EIA report is reviewed by relevant authorities, including FEPA, which may
involve public consultations to gather feedback from stakeholders.
6. Decision-Making:
Based on the review, an Environmental Impact Statement (EIS) is issued, outlining
approved mitigation measures and conditions for project implementation.
7. Monitoring and Auditing:
Continuous monitoring of project implementation to ensure compliance with
environmental standards and mitigation measures outlined in the EIS.
Challenges in Implementation
Despite a robust legislative framework, several challenges hinder effective EIA
implementation in Nigeria:
i. Multiple Regulatory Bodies: Overlapping responsibilities among various agencies can
lead to confusion and inefficiencies in the EIA process.
ii. Capacity Constraints: Limited technical expertise and resources within regulatory
agencies can affect the quality of EIAs conducted.
iii. Public Participation: Insufficient engagement with local communities often results in
inadequate consideration of local knowledge and concerns.
iv. Compliance Monitoring: Weak enforcement mechanisms may lead to non-compliance
with EIS conditions by project proponents.
Conclusion
The legislative background of Environmental Impact Assessment in Nigeria is anchored in the
Environmental Impact Assessment Act No. 86 of 1992, which mandates comprehensive
assessments for major development projects. While this framework provides essential

25
guidelines for protecting environmental integrity, challenges remain that need to be addressed
to enhance the effectiveness of EIAs in promoting sustainable development across Nigeria.
Strengthening institutional capacity, improving public participation, and clarifying regulatory
roles will be critical steps toward achieving effective environmental governance through EIAs.

26
 Current EIA Practices in Developed And Developing Countries
Environmental Impact Assessment (EIA) practices vary significantly between developed and
developing countries, influenced by factors such as regulatory frameworks, institutional
capacities, public participation, and socio-economic contexts. This analysis highlights key
differences and similarities in EIA practices across these two categories of countries.

EIA Practices in Developed Countries

1. Established Regulatory Frameworks:
i. Developed countries typically have comprehensive legal frameworks governing
EIA processes. For instance, the United States established the National
Environmental Policy Act (NEPA) in 1969, which mandates thorough
environmental assessments for federal projects. Similarly, the European Union has
directives that standardize EIA practices across member states.
ii. These frameworks ensure that EIAs are integrated into the project planning and
decision-making processes from the outset.
2. Robust Methodologies:
i. Developed nations employ sophisticated methodologies for conducting EIAs,
including quantitative modeling, cost-benefit analysis, and multi-criteria decision
analysis. These methods enhance the quality of assessments and provide a clearer
understanding of potential impacts.
ii. The use of Geographic Information Systems (GIS) and advanced simulation tools
is common to analyze spatial impacts effectively.
3. Public Participation:
i. Public involvement is a critical component of EIA in developed countries.
Stakeholders are engaged throughout the assessment process, from scoping to
review stages. This engagement fosters transparency and accountability.
ii. Mechanisms for public consultation often include public hearings, comment
periods on draft assessments, and stakeholder workshops.
4. Post-Implementation Monitoring:
i. There is a strong emphasis on monitoring and evaluation post-implementation in
developed countries. Regulatory agencies often require ongoing assessments to
ensure compliance with mitigation measures outlined in the EIA.
ii. This practice helps to identify unforeseen impacts and adapt management strategies
accordingly.

27
 EIA Practices in Developing Countries
1. Emerging Legal Frameworks:
i. Many developing countries have adopted EIA legislation since the 1970s and 1980s
but often lack comprehensive regulatory frameworks comparable to those in
developed nations. The implementation of these laws can be inconsistent due to
various challenges.
ii. For example, while some countries have established EIA requirements, the
enforcement of these regulations is frequently weak or poorly coordinated among
agencies.
2. Limited Methodologies:
i. Developing countries often use simplified methodologies for conducting EIAs due
to constraints such as limited financial resources, technical expertise, and access to
data. Common methods may include checklist approaches or ad hoc assessments
rather than rigorous quantitative analyses.
ii. As noted in studies, many EIAs are conducted primarily to fulfill legal requirements
rather than as genuine efforts to assess environmental impacts comprehensively
3. Challenges in Public Participation:
i. Public participation in the EIA process is often limited in developing countries due
to factors such as lack of awareness among communities, inadequate outreach
efforts by project proponents, and cultural barriers that hinder effective
engagement.
ii. In some cases, traditional practices may not be adequately respected during
consultations, leading to conflicts over project implementation
4. Weak Monitoring Systems:
i. Post-implementation monitoring is generally less robust in developing countries
compared to developed ones. Many projects do not undergo sufficient follow-up
assessments to evaluate compliance with mitigation measures or to address
unforeseen impacts.
ii. This lack of monitoring can result in significant environmental degradation that was
not anticipated during the initial assessment phase
Comparative Analysis
i. Integration into Decision-Making: In developed countries, EIAs are typically well-
integrated into broader planning processes, while in developing nations, EIAs may be
treated as standalone exercises with limited influence on final project decisions.

28
 ii. Capacity Building Needs: Developing countries often require capacity building to
enhance their EIA practices. International organizations have initiated training programs
aimed at improving technical expertise and institutional frameworks for effective EIA
implementation
iii. Cultural Sensitivity: In both contexts, there is a growing recognition of the need for
culturally sensitive approaches to public participation and stakeholder engagement.
However, developing countries face unique challenges related to traditional governance
structures that can complicate these efforts
Conclusion
Current EIA practices reveal significant disparities between developed and developing
countries. While developed nations benefit from established regulatory frameworks and robust
methodologies that emphasize public participation and post-implementation monitoring,
developing countries face challenges related to enforcement, capacity limitations, and
community engagement. Addressing these gaps through capacity building, improved
regulatory enforcement, and culturally sensitive engagement strategies will be crucial for
enhancing EIA effectiveness globally.
