Difficulty: HardTransportation, Communication, and Commercial Trade in Nigeria

Arrange the following commercial river ports and navigation hubs along the River Niger in Nigeria in geographical sequence, starting from the most upstream northern location to the lower southern course.

  1. 1Yelwa
  2. 2Jebba
  3. 3Lokoja
  4. 4Onitsha

Answer

The correct sequence from upstream (north) to downstream (south) along the River Niger is Yelwa, followed by Jebba, Lokoja, and finally Onitsha.
Following the course of the River Niger from north to south within Nigeria: Yelwa (Kebbi State) is at the upper reaches near Lake Kainji; Jebba (Kwara State) is along the middle course below Kainji; Lokoja (Kogi State) sits at the confluence with the Benue River; and Onitsha (Anambra State) lies along the lower course leading into the Niger Delta region.

Step-by-Step Solution

1
Identify the northernmost inland river port where the River Niger flows through north-western Nigeria.
Yelwa in Kebbi State is located on the upper course of the Niger River upstream of Lake Kainji.
The River Niger enters Nigeria from the north-west, making Yelwa the most upstream of the listed river ports.
2
Determine the middle course navigation and bridging point below Lake Kainji.
Jebba in Kwara State lies along the middle course of the River Niger.
Jebba is located south of Kainji Lake and upstream of the Niger-Benue confluence.
3
Locate the major confluence port where the River Benue joins the River Niger.
Lokoja in Kogi State is positioned at the confluence of the Niger and Benue rivers.
Lokoja receives the flow from both Jebba (Niger) and Makurdi (Benue) before the unified river flows south.
4
Identify the lower river port servicing commercial trade in south-eastern Nigeria before the delta distributaries.
Onitsha in Anambra State is situated on the east bank of the lower River Niger.
Onitsha is the southernmost of these inland river ports before the river splits into its delta network.
