(a) Briefly outline the views of Thomas Malthus about population. (b) How valid are such views about the Nigerian situation today?

Answer Details

(a) Malthus's views on population. Thomas Malthus, in his Essay on the Principle of Population, argued that:

• Population, if unchecked, tends to grow in a geometric progression (1, 2, 4, 8, 16...), that is, it doubles over regular periods.
• The food (means of subsistence) supply can at best grow only in an arithmetic progression (1, 2, 3, 4, 5...).
• Therefore population tends to outstrip the food supply, leading to a shortage of food and a falling standard of living.
• This imbalance is corrected by checks. Positive (natural) checks such as famine, disease, and war raise the death rate, while preventive (moral) checks such as late marriage and moral restraint lower the birth rate.

(b) Validity of these views for Nigeria today.

Points that support Malthus:

• Nigeria has a high population growth rate that has at times outpaced growth in food production, contributing to food shortages, importation of food, and unemployment.
• Poverty, pressure on land, and evidence of positive checks such as disease and communal conflict can still be observed.

Points that weaken Malthus:

• Modern improvements in agricultural technology (fertilisers, high-yield seeds, irrigation, mechanisation) have raised food output faster than Malthus assumed possible, so food need not grow only arithmetically.
• Family planning and education provide preventive checks Malthus underrated, helping to slow birth rates.
• Nigeria can import food and export other goods, and can develop industry, so it is not limited to its own farmland.
• A larger population also provides a bigger labour force and market that can aid development.

Conclusion. Malthus's warning about the danger of unchecked population growth outstripping resources is partly valid for Nigeria, but his theory is not fully borne out because technology, trade, and family planning have loosened the fixed relationship he assumed between population and food.

Examination takeaway. For a "how valid" question, give a balanced answer: state points for and against, then reach a reasoned conclusion rather than accepting or rejecting the theory outright.
