Question map
Which one of the following is a part of the Congo Basin?
Explanation
The correct answer is Option 1: Cameroon.
The Congo Basin is the sedimentary basin of the Congo River, spanning across West Equatorial Africa. It is the world's second-largest tropical rainforest. The basin encompasses parts of six countries: Cameroon, Central African Republic, Democratic Republic of the Congo, Republic of the Congo, Equatorial Guinea, and Gabon.
- Cameroon: Significant portions of southern and eastern Cameroon fall within the Basin, contributing to its rich biodiversity.
- Nigeria: Located to the west of the basin, it is primarily part of the Niger River Basin.
- South Sudan: Situated to the northeast, its geography is dominated by the Nile River system (the Sudd).
- Uganda: While bordering the Great Lakes region, it lies within the Nile Basin, separated from the Congo Basin by the East African Rift.
Therefore, among the given options, only Cameroon is geographically integrated into the Congo Basin ecosystem.
PROVENANCE & STUDY PATTERN
Full viewA classic map-overlay question. It tests if you can distinguish 'West Africa' (Nigeria/Niger River) from 'Central Africa' (Congo Basin). Standard books like Majid Hussain explicitly list Cameroon, making this a fair reward for students who visualize biome boundaries rather than just memorizing lists.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Explicitly lists Congo Basin and names Cameroon among the equatorial African areas of the Congo Basin.
- Directly connects the Congo Basin region with Cameroon as one of the constituent countries.
- Identifies the Congo Basin as the major area of tropical evergreen rainforest in Africa.
- Establishes the Congo Basin's geographic identity within Africa, supporting country-level inclusion statements.
- Provides an explicit list of countries that the Congo Basin sweeps across.
- Nigeria is not included in that list, so the Congo Basin does not include Nigerian territory according to this source.
- States that the rainforest 'straddles six countries in Central Africa', indicating the basin is confined to those countries.
- No mention of Nigeria among those countries, supporting that Nigeria is not part of the Congo Basin.
Gives a definition/example: the Congo River basin is a large African basin draining to the Atlantic and lists its basin area and continent (Africa).
A student can compare the Congo basin's geographic extent on a map with Nigeria's location to see if Nigeria lies inside that drainage area.
Lists countries on the equator including Gabon, Congo, Democratic Republic of Congo and others but does not list Nigeria.
Use a world map to note which central African equatorial countries are associated with the Congo Basin and check whether Nigeria is among them.
Describes human activity in the Congo Basin (Pygmies gathering nuts), implying the basin is located in central African rainforest regions.
Compare central African rainforest/Congo Basin regions with Nigeria's forest/river systems on a map to judge overlap.
Mentions 'isolated pockets in Congo Basin' alongside a list of interior parts of other named countries, indicating the basin is a distinct regional area.
Treat the Congo Basin as a distinct regional unit and check political maps to see which countries it covers; test whether Nigeria is included.
Lists Nigeria and Congo as separate countries (here as OPEC members), reinforcing they are distinct political entities.
Use this to remind that having similar regional labels doesn't imply political overlap — consult a drainage/basin map to verify if Nigeria is within the Congo Basin.
- Explicitly names 'parts of South Sudan' as included in the Congo Basin.
- Puts South Sudan in the eastern portion of the basin, supporting that territory of South Sudan lies within the Congo Basin.
States that the Congo Basin is the large tract of tropical evergreen rainforest in the equatorial regions of Africa.
A student could compare a map of equatorial African rainforest (Congo Basin) with South Sudan's location to see if South Sudan lies in that equatorial rainforest zone.
Lists countries in a rainforest/Congo-Basin-related coalition (e.g., Cameroon, Central African Republic, Congo, DRC, Equatorial Guinea, Gabon, Uganda) indicating the nations commonly associated with the Congo Basin region.
A student could check whether South Sudan appears in such country-lists or on maps of the listed countries to judge if it is usually treated as part of the Congo Basin.
Gives an example of human activity tied specifically to the Congo Basin (Pygmies gathering nuts), reinforcing that the Congo Basin refers to a particular ecological/ethnic zone in Africa.
One could look at ethnographic or ecological maps showing where Pygmy populations and that habitat occur relative to South Sudan's borders.
Describes the savanna (Sudan) climate as a transitional belt between equatorial forests and deserts and notes its position in East Africa.
A student can use this climatic-zone pattern to assess whether South Sudan falls in the savanna (transitional) belt or in the equatorial rainforest belt (Congo Basin) on a regional map.
Explains the geographical extent of the Sudan/savanna climate as a belt that curves southwards in East Africa, marking the transition from equatorial forests.
Compare the described savanna belt locations with South Sudan's location to infer whether South Sudan is more likely in the savanna transition zone or within the equatorial Congo Basin.
- Explicitly lists Uganda among countries of the Congo Basin (equatorial region of Africa).
- Links the Congo Basin with specific countries, including Uganda, in a geographic/land-use context.
- Groups Uganda together with Congo and Democratic Republic of Congo in a list of equatorial countries, consistent with Congo Basin location.
- Places Uganda in the same regional band (equator) that overlaps with the Congo Basin.
- Shows the Congo River basin as a large African basin, implying it spans multiple central/equatorial African countries.
- Provides basin-scale context supporting that the Congo Basin covers extensive territory in central Africa.
- [THE VERDICT]: Sitter. Directly supported by Majid Hussain (Ch. 10 & 3) and standard Oxford Student Atlas.
- [THE CONCEPTUAL TRIGGER]: Global Drainage Systems & Biomes. Specifically, the overlap between the Equatorial Rainforest belt and political borders.
- [THE HORIZONTAL EXPANSION]: Memorize the 'Congo 6' (DRC, ROC, CAR, Cameroon, Gabon, Eq. Guinea). Contrast with the 'Nile Basin' (Uganda, South Sudan, Egypt) and 'Niger Basin' (Nigeria, Mali, Niger).
- [THE STRATEGIC METACOGNITION]: Apply the 'River Identity' logic. Countries are often defined by their main river. Nigeria is the Niger. Uganda is the Nile source. The Congo Basin defines Central Africa, and Cameroon is the gateway to Central Africa.
The Congo Basin is a major equatorial African region that includes Central African countries such as Cameroon.
High-yield for geography and environment questions: knowing which countries lie in major bioregions helps answer location, climate, and resource questions. Connects to political geography (borders, regional organizations) and physical geography (rainforest distribution). Useful for map-based and short-answer questions asking which nations a region spans.

The 'Cuvette Centrale' Peatlands. Located in the Congo Basin (DRC/ROC), it is the world's largest tropical peatland complex. Expect a question on this specific carbon sink or the 'Sangha Tri-National' landscape.
Use the 'River-Name' Heuristic. Nigeria is named after the Niger River (West Africa). Uganda is the reservoir of the Nile (East Africa). South Sudan is the Sudd Wetland (Nile). By simple geographic elimination, Cameroon (Central Africa) is the only candidate left for the Congo Basin.
Mains GS-3 (Environment): Use the Congo Basin as a case study for 'Global Commons'. Mention the 'Central African Forest Initiative (CAFI)' when discussing international climate finance, contrasting it with the Amazon Fund.
