Here is the solution to Question 1: Question 1 a) Describe the major relief divisions of West Africa. West Africa's relief can be broadly categorized into three main divisions: • Coastal Plains: These are low-lying, flat to gently undulating areas found along the Atlantic coastline. They are generally narrow but can widen significantly in areas like the Niger Delta. These plains are often characterized by lagoons, estuaries, and mangrove swamps, and their elevation is typically close to sea level. • Interior Lowlands and Plains: Inland from the coastal plains, much of West Africa consists of vast, relatively flat or gently undulating plains. These include the Chad Basin, the Sokoto Plains, and the extensive plains surrounding the Niger River. Elevations in these areas are generally below 500 meters, forming a large, relatively uniform expanse. • Highlands and Plateaux: Scattered throughout the region are several elevated areas. Notable examples include the Fouta Djallon Highlands in Guinea, which serve as a major watershed; the Jos Plateau in central Nigeria, known for its higher altitude and cooler climate; the Adamaoua Plateau extending from Cameroon into Nigeria; and the Atacora Mountains in Togo and Benin. These areas feature higher elevations, often with steeper slopes and rugged terrain. b) Explain four ways in which relief affects agriculture in West Africa. 1. Slope and Soil Erosion: Steep slopes in highland areas increase the risk of soil erosion, washing away fertile topsoil and making cultivation difficult. This limits the types of crops that can be grown and often requires labor-intensive terracing. Conversely, flat or gently sloping plains are less prone to erosion and are easier to cultivate. 2. Drainage and Water Availability: Low-lying areas, particularly river floodplains (e.g., along the Niger River), often have fertile alluvial soils and good water availability, making them ideal for crops like rice. However, very low-lying areas can suffer from waterlogging. Higher relief areas can be sources of rivers, providing water for irrigation in downstream agricultural zones. 3. Altitude and Climate: Higher altitudes, such as the Jos Plateau, experience cooler temperatures and often higher rainfall compared to surrounding lowlands. This allows for the cultivation of specific crops that thrive in temperate or sub-tropical conditions, such as certain vegetables or tea, which would not grow well in the hotter lowlands. 4. Accessibility and Mechanization: Flat or gently undulating relief facilitates the use of agricultural machinery and provides easier access to farms, promoting large-scale commercial farming. In contrast, rugged or mountainous terrain makes mechanization challenging, often limiting agriculture to small-scale, manual farming practices. c) Outline five factors responsible for the low level of industrial development in West Africa. 1. Inadequate Infrastructure: Poor and insufficient infrastructure, including unreliable power supply, inadequate transportation networks (roads, railways, ports), and limited access to clean water, significantly increases production costs and hinders industrial efficiency. 2. Limited Capital and Investment: West African countries often face a shortage of domestic capital for industrial investment. Foreign direct investment is also frequently low due to perceived political instability, high operational risks, and small market sizes. 3. Small Domestic Markets: The generally low purchasing power of the population in many West African countries results in small domestic markets. This makes it difficult for industries to achieve economies of scale and sustain large-scale production. 4. Lack of Skilled Labour and Technology: There is often a scarcity of technically skilled personnel, engineers, and managers required to operate and maintain modern industrial facilities. Access to appropriate technology and investment in research and development are also limited. 5. Political Instability and Corruption: Frequent political changes, conflicts, and high levels of corruption create an uncertain and unfavorable business environment. This deters both local and foreign investors from making long-term commitments to industrial projects. d) With examples, distinguish between: (i) Regional migration Regional migration refers to the movement of people within a specific geographical region, often across national borders but within the same continent or sub-region. It typically involves movement between neighboring countries. Example: People from Burkina Faso migrating to Côte d'Ivoire to work on cocoa farms. (ii) Seasonal migration Seasonal migration is the temporary movement of people from one area to another in response to seasonal changes, usually for work related to agriculture, fishing, or tourism. Migrants typically return to their original homes after the season ends. Example: Pastoralists in the Sahel region moving their livestock to different pastures based on the availability of water and fodder during wet and dry seasons. (iii) Rural–urban migration Rural–urban migration is the movement of people from rural areas (villages, countryside) to urban areas (towns, cities). This type of migration is primarily driven by the search for better economic opportunities, education, healthcare, and social amenities available in cities. Example: Young people moving from a farming village in northern Ghana to Accra in search of employment and improved living standards. 3 done, 2 left today. You're making progress.
