(a) Sketch map of Nigeria

(b) Factors impeding the development of solar energy in Nigeria

1. High capital cost: Solar panels, batteries, inverters and other components are expensive to import, install and replace.
2. Inadequate technical manpower: There are too few trained personnel to manufacture, install, repair and maintain solar-energy equipment.
3. Inadequate government support and policy: Insufficient funding, weak policy implementation and low public awareness discourage large-scale investment in solar energy.

(c) Problems created by the construction of Kainji Dam in Nigeria

1. Displacement of people: The creation of Lake Kainji flooded settlements, forcing many people to leave their homes and be resettled.
2. Loss of agricultural and grazing land: Cultivatable land and pasture were submerged by the reservoir, reducing land available for farming and livestock rearing.
3. Spread of water-borne diseases: The reservoir provides favourable conditions for diseases such as bilharzia, while mosquitoes breeding around the water may increase malaria incidence.
4. Disruption of traditional occupations and transport: Fishing, river transport and other activities along the former river channel, especially downstream, were disrupted; fish movement was also affected by the dam.
