Tropical and sub-tropical crops can be broadly defined as those that have their origin or are grown commercially in the tropics or sub-tropics. Strictly speaking, the tropics extend between the Tropics of Cancer and Capricorn, at 23° north and south of the equator. Agronomically speaking, these boundaries are too rigid.The expansion of horticultural production in these regions has come as a result of a growing export market focus as well as the ability to get earlier market access within the domestic market.
Despite this, challenges remain with rainfall variability, cost of transport, labour availability and, above all, the effects of wind (nearly all major production areas have suffered loss as a consequence of cyclones) limiting the potential of various crops.
