Principles of demand

Demand in agricultural economics simply means the quantity of agricultural products that consumers are willing and able to buy at a particular price during a specific period. Think of it as the desire backed by money – wanting something is not enough; you must have the cash to pay for it.

In Nigeria, for example, the demand for tomatoes increases significantly during the dry season when fresh supplies become scarce. Families still want tomatoes for their meals, and those with money will buy them even at higher prices. This is demand – real purchasing power meeting real need.

Several factors affect demand, including price, income levels, population size, and consumer preferences. Understanding demand helps farmers decide what crops to grow and in what quantities. If demand for a product is high, farmers can increase production to make more profit.
