(a) Outline map of Nigeria showing internal (domestic) trade

A drawn outline map of Nigeria is required. On it, locate and name the source and destination of two major internal-trade items, join each source to its destination with an arrow showing the direction of movement, and name one important town in each area. Suitable examples:

• Foodstuffs/grains (millet, beans, cattle): source area the far North (Kano), moving southward to the destination market of Lagos/Onitsha in the south. Arrow points from north to south. Towns: Kano (source), Lagos (destination).
• Palm oil and kola/timber (or petroleum products): source area the South (Aba/Port Harcourt), moving northward to Kaduna/Kano. Arrow points from south to north. Towns: Port Harcourt (source), Kaduna (destination).

(Other acceptable items: yam/cassava from the middle belt to the cities, salt/imported goods from the coast inland, cement, fish from the coast to the interior.)

(b) Four factors that have favoured the development of internal trade in Nigeria

1. Regional differences in products: the north produces grains, cattle and groundnuts while the south produces oil palm, yam, kola and petroleum, so surpluses are exchanged between regions.
2. Improved transport network: the spread of roads, railways and waterways links producing and consuming areas.
3. Large population and big urban markets: a large home population and growing cities create strong demand for goods.
4. A common currency and a single national market: the same currency, common language of trade and absence of internal customs barriers ease exchange.

(Also: presence of periodic markets and trading networks, and government encouragement/peace and stability.)
