Difficulty: EasyEnvironmental Hazards, Degradation, and Management

Match each environmental hazard in Nigeria with its primary environmental impact.

  • Oil SpillagePollution of freshwater aquifers and destruction of mangrove ecosystems in the Niger Delta
  • Coastal ErosionRetreat of the coastline and destruction of beachfront property in Lagos
  • Indiscriminate Refuse DisposalBlockage of urban storm drains leading to flash floods in municipal areas

Answer

Oil Spillage pairs with contamination of aquatic and mangrove ecosystems in the Niger Delta; Coastal Erosion pairs with shoreline retreat and beachfront damage in Lagos; Indiscriminate Refuse Disposal pairs with drain blockages causing urban flash floods.
Each hazard is accurately matched to its principal ecological or infrastructural consequence in Nigeria based on regional environmental geography.

Step-by-Step Solution

1
Identify the primary geographic location and ecological impact of crude oil discharge.
Oil spillage directly contaminates creeks, soil, and mangrove swamps in the Niger Delta.
Petroleum exploration activities are concentrated in the coastal Niger Delta region.
2
Analyze oceanographic processes along coastal settlements like Lagos.
Wave scouring along the Atlantic oceanfront causes coastal erosion and land loss on Victoria Island and surrounding shores.
High-energy Atlantic waves continuously scour unprotected sandy shores.
3
Evaluate urban human activities regarding waste management.
Dumping trash into gutters causes drainage clogging and severe flash flooding during heavy rainstorms.
Unmanaged solid waste obstructs surface runoff routes in major cities.
