Answer

Scoping pairs with identifying key environmental issues and boundaries; Baseline Assessment pairs with documenting pre-project environmental conditions; Mitigation Planning pairs with formulating measures to prevent or reduce adverse impacts; and Environmental Auditing pairs with evaluating post-implementation performance and compliance.
Each EIA stage serves a unique functional role in environmental management: Scoping identifies key focus areas and boundaries; Baseline Assessment documents existing pre-project conditions; Mitigation Planning formulates actions to reduce or avoid negative impacts; and Environmental Auditing evaluates compliance during and after project implementation.

Step-by-Step Solution

1
Define the primary purpose of Scoping in the EIA process
Scoping identifies the key issues, temporal and spatial boundaries, and focus areas for the EIA report.
It ensures resources are directed toward evaluating significant potential impacts.
2
Define the role of Baseline Assessment
Baseline assessment gathers data on existing physical, biological, and socio-economic parameters prior to project commencement.
A baseline benchmark is required to accurately detect future project-induced environmental changes.
3
Define the objective of Mitigation Planning
Mitigation planning develops targeted actions to prevent, minimize, or remediate predicted environmental damage.
It converts impact predictions into actionable environmental protection plans.
4
Define the function of Environmental Auditing
Environmental auditing reviews post-project operations against environmental management plans and regulatory standards.
Auditing occurs post-construction to verify compliance and audit management effectiveness.

An environmental consulting team is preparing an Environmental Impact Assessment (EIA) for a proposed open-cast solid mineral mining operation in Plateau State, Nigeria. How should the following initial procedural steps of the EIA process be arranged in the correct chronological order from start to finish?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence of the EIA steps is: Screening the proposed project -> Scoping the project area -> Conducting baseline environmental data collection -> Predicting potential environmental impacts and formulating mitigation measures -> Drafting and submitting the Environmental Impact Statement (EIS).
The Environmental Impact Assessment (EIA) process follows a logical sequence. It begins with screening (determining EIA necessity), moves to scoping (defining scope and key issues), proceeds to baseline data collection (measuring existing environmental conditions), follows with impact prediction and mitigation design, and concludes with the submission of the Environmental Impact Statement (EIS) for review and approval.

Step-by-Step Solution

1
Identify the initial screening decision.
Screening occurs first to determine whether a project legally mandates an EIA.
Before resources are committed to studies, regulatory agencies must decide if an assessment is required.
2
Define the boundaries and key issues of the assessment.
Scoping occurs second, defining the specific scope, key concerns, and environmental parameters.
Scoping ensures that subsequent fieldwork focuses strictly on significant environmental impacts.
3
Establish the baseline environmental conditions.
Baseline data collection occurs third to measure pre-existing environmental quality.
Comprehensive baseline data provides the reference standard against which future impacts are evaluated.
4
Analyze future impacts and develop management controls.
Impact prediction and mitigation formulation take place fourth.
Baseline data is analyzed to forecast environmental changes and design measures that avoid or reduce damage.
5
Produce and submit the final assessment documentation.
Drafting and submitting the Environmental Impact Statement (EIS) is the final procedural step among those listed.
The EIS synthesizes baseline data, impact evaluations, and management strategies for stakeholder review and approval.

Question 84Question →

Under the National Environmental Standards and Regulations Enforcement Agency (NESREA) Act of 2007, the agency is legally mandated to enforce compliance with international environmental treaties, conventions, and protocols to which Nigeria is a signatory.

Show answer & explanation

Answer: True

Answer

The statement is TRUE.
The statement is correct because the National Environmental Standards and Regulations Enforcement Agency (NESREA) Act of 2007 specifically empowers the agency under Section 7(c) to enforce compliance with international environmental treaties, conventions, and protocols to which Nigeria is a signatory.

Step-by-Step Solution

1
Examine the statutory powers granted under the NESREA Act of 2007.
Section 7 of the legislation outlines the specific enforcement responsibilities of the agency.
Determining agency jurisdiction requires analyzing its enabling legislation.
2
Assess whether NESREA's mandate includes international environmental agreements.
Section 7(c) explicitly instructs NESREA to enforce compliance with all international environmental treaties, protocols, and conventions ratified by Nigeria.
Domestic agencies in Nigeria are given statutory responsibility to execute international treaty commitments.

Question 87Question →

The National Agency for the Great Green Wall (NAGGW) in Nigeria is legally mandated to monitor and enforce industrial effluent discharge standards across urban manufacturing zones.

Show answer & explanation

Answer: False

Answer

False. The primary mandate of NAGGW is to combat desertification and land degradation in northern Nigeria, not to regulate urban industrial effluent discharges.
The statement is false because NAGGW was created specifically to address desertification, land degradation, and drought mitigation in Nigeria's northern savanna and Sahel regions, whereas industrial effluent monitoring is enforced by NESREA and relevant state environmental bodies.

Step-by-Step Solution

1
Analyze the statutory responsibility of the National Agency for the Great Green Wall (NAGGW).
NAGGW is tasked with halting desertification, controlling drought impacts, and promoting afforestation across 11 frontline states in northern Nigeria.
Understanding the specialized geographical and environmental focus of NAGGW prevents misattributing urban industrial regulatory duties to it.
2
Identify the Nigerian regulatory agency empowered to enforce industrial pollution standards.
The National Environmental Standards and Regulations Enforcement Agency (NESREA) holds the statutory authority to enforce environmental regulations, including industrial effluent limits.
Comparing agency mandates confirms that industrial effluent oversight belongs to NESREA, making the statement false.
