Answer Details

(a) Six factors that limit food production in West Africa

Inadequate finance/capital and credit for farmers.
Use of poor tools and low level of mechanisation.
Pests and diseases of crops and livestock.
Unfavourable/unreliable climate (drought, erratic rainfall).
Poor storage, processing and transport facilities leading to high losses.
Poor/infertile soils, land tenure problems, and inadequate improved inputs (seeds, fertilizer).

(b) Solar energy as a source of farm power

Three advantages:

It is free, renewable and inexhaustible once the equipment is installed.
It is clean and does not pollute the environment.
It requires little maintenance and can be used in remote areas without a power grid.

Three disadvantages:

It is not available at night and is unreliable on cloudy/rainy days.
The initial cost of the equipment (panels, batteries) is high.
It produces relatively small amounts of power and requires storage (batteries) for continuous use.
