Difficulty: Very hardEnvironmental Impact Assessment and Management Strategies

A proposed infrastructural development along the Lagos coastal wetland zone requires a comprehensive evaluation to ensure environmental compliance and sustainability. Which of the following procedural sequences accurately traces the stages of an Environmental Impact Assessment (EIA) from initial proposal to post-implementation monitoring?

  1. A
    Scoping →\rightarrow Screening →\rightarrow Impact prediction →\rightarrow Baseline environmental assessment →\rightarrow Mitigation planning →\rightarrow Environmental auditing →\rightarrow Environmental Impact Statement submission
  2. B
    Screening →\rightarrow Baseline environmental assessment →\rightarrow Scoping →\rightarrow Impact prediction →\rightarrow Environmental auditing →\rightarrow Mitigation planning →\rightarrow Environmental Impact Statement submission
  3. Screening →\rightarrow Scoping →\rightarrow Baseline environmental assessment →\rightarrow Impact prediction →\rightarrow Mitigation planning →\rightarrow Environmental Impact Statement submission →\rightarrow Environmental auditingAnswer
  4. D
    Baseline environmental assessment →\rightarrow Screening →\rightarrow Scoping →\rightarrow Impact prediction →\rightarrow Mitigation planning →\rightarrow Environmental auditing →\rightarrow Environmental Impact Statement submission

Answer

Screening →\rightarrow Scoping →\rightarrow Baseline environmental assessment →\rightarrow Impact prediction →\rightarrow Mitigation planning →\rightarrow Environmental Impact Statement submission →\rightarrow Environmental auditing
The correct sequence follows the standard international and Nigerian (FMEnv) Environmental Impact Assessment procedure. Screening determines necessity, scoping sets boundaries, baseline data collection measures existing conditions, impact prediction models expected changes, mitigation planning formulates management strategies, EIS submission presents findings for approval, and environmental auditing evaluates post-project compliance.

Step-by-Step Solution

1
Determine legal and ecological requirement for EIA
Screening stage establishes whether the coastal project requires a full EIA based on environmental thresholds.
Screening prevents unnecessary assessment costs for low-impact projects while flagging high-risk developments.
2
Define spatial, temporal, and thematic boundaries of the evaluation
Scoping identifies key environmental issues, stakeholders, and parameters to be investigated.
Scoping ensures the EIA focuses strictly on significant potential environmental impacts.
3
Collect existing environmental data prior to project execution
Baseline environmental assessment documents pre-development physical, biological, and socio-economic conditions.
Baseline data is essential to establish a reference state against which future changes are measured.
4
Forecast potential environmental alterations and devise risk controls
Impact prediction quantifies changes, followed by mitigation planning to avoid, reduce, or offset negative impacts.
Proactive mitigation design integrates environmental protection measures directly into project construction plans.
5
Formalize findings and execute post-project monitoring
Submission of the Environmental Impact Statement (EIS) allows regulatory review, followed by post-implementation environmental auditing.
Auditing verifies compliance with approved mitigation measures during and after project operation.
