Question 1

(1a) Diagram/Map:

(1b) Economic importance of iron ore to Nigeria:

• (i) Source of raw materials for industries: Iron ore is the principal raw material used in the production of iron and steel. The steel produced is used in construction, automobile manufacturing, railway development, and the production of machinery and household equipment. This promotes industrial growth in Nigeria.
• (ii) Generation of employment opportunities: The mining, processing, transportation, and marketing of iron ore create employment opportunities for miners, engineers, geologists, technicians, drivers, and traders. This helps reduce unemployment and improve the standard of living.
• (iii) Source of revenue and foreign exchange: Iron ore mining generates revenue for the government through taxes, royalties, and licensing fees. When exported, it earns foreign exchange, which contributes to the country’s economic growth and balance of trade.

(1c) Problems associated with iron ore mining in Nigeria:

• (i) Inadequate capital for mining operations.
• (ii) Poor transportation and other infrastructural facilities.
• (iii) Lack of modern mining equipment and technology.
• (iv) Environmental pollution and land degradation.
• (v) Inadequate government support and inconsistent policies.

Question 2

(2b) Uses of lowlands in Nigeria:

• (i) Agricultural activities: The lowlands have fertile soils and relatively gentle slopes, making them suitable for the cultivation of crops such as rice, cassava, yam, and oil palm.
• (ii) Settlement development: The flat and accessible nature of the lowlands encourages the establishment and growth of towns and villages because building houses and other structures is easier.
• (iii) Transportation and communication: Roads, railways, and other transport facilities can be constructed more easily and cheaply on lowlands than on highlands, thereby promoting movement and communication.
• (iv) Industrial and commercial development: Many industries and commercial centres are located in lowland areas because of the availability of land, labour, and transportation facilities.
• (v) Fishing and water transportation: Some lowland areas, especially the coastal and riverine plains, contain rivers, creeks, and lagoons that support fishing activities and inland water transport.

Question 3

(3a) Definition of transportation:

Transportation is the movement of people, goods, and services from one place to another through various means such as road, rail, water, air, and pipelines. It facilitates communication, trade, and economic activities by linking producers with consumers and connecting different parts of a country.

(3b) Importance of transportation to Nigeria's economy:

• (i) It facilitates the movement of goods and services from producers to consumers.
• (ii) It promotes trade and commerce within and outside the country.
• (iii) It creates employment opportunities in the transport sector.
• (iv) It encourages industrial and agricultural development.
• (v) It promotes national integration and economic growth.

(3c) Reasons why road transport is the most popular means of transport in Nigeria:

• (i) Wide accessibility: Roads extend to most rural and urban areas of Nigeria, making it possible for people and goods to reach places where railways, airports, and seaports are unavailable.
• (ii) Door-to-door service: Road transport carries passengers and goods directly from the point of origin to the destination without requiring additional means of transport.
• (iii) Relatively low cost of construction: Roads are generally cheaper and easier to construct and maintain than railways, airports, and waterways, making them more common throughout the country.
• (iv) Flexibility and convenience: Road transport operates at any time and allows users to choose routes, schedules, and destinations according to their needs.

Question 6

(6a) Differences between nomadic pastoralism and cattle ranching:

• (i) Movement of animals: In nomadic pastoralism, herders move from one place to another with their livestock in search of water and pasture while in cattle ranching, livestock are kept permanently within a fenced ranch and are not moved from place to place.
• (ii) Method of management: Nomadic pastoralism is generally practiced using traditional methods with little investment and limited facilities, whereas cattle ranching involves modern methods, improved breeds, veterinary services, and better management practices.

(6b) Problems of nomadic pastoralism in Nigeria:

• (i) Frequent conflicts with farmers: Nomadic herders often move through farmlands, leading to the destruction of crops and resulting in clashes between herders and farmers.
• (ii) Spread of diseases: The constant movement of livestock exposes animals to various diseases and parasites, which may spread rapidly among herds.
• (iii) Scarcity of pasture and water: During the dry season, pasture and water become scarce, making it difficult to feed and maintain livestock.
• (iv) Cattle theft and insecurity: Nomadic herders are often exposed to cattle rustling, bandit attacks, and other security challenges while moving from one place to another.

(6c) Solutions to the problems of nomadic pastoralism:

• (i) Establishment of grazing reserves and ranches: Governments should establish grazing reserves and encourage ranching to reduce the movement of cattle into farmlands.
• (ii) Effective conflict resolution and law enforcement: Authorities should enforce laws, settle disputes promptly, and punish offenders to prevent violence.
• (iii) Provision of water and pasture facilities: The government should provide water points, grazing areas, and veterinary services to reduce competition for land and resources.
