An agricultural recession describes a period of low crop prices and sharply reduced farm incomes.
A common theme of agricultural recessions, as opposed to famines and crop failures was that they tended to be linked to market conditions, often the opening up of new areas of production and the ability to bring crops into previously markets that had previously protected either by high transport costs (as in the nineteenth century) or by a war blockade (as after the Napoleonic and First World Wars).
[1] An early agricultural recession was the Post-Napoleonic Depression where British agriculture was faced with cheap grain from Europe as Continental producers could freely export grain after two decades.
The Great depression of British agriculture, which had parallels in other European countries like France[1] and Italy, was largely as a result of globalization as railways and steam ships together with some farm mechanisation meant that fertile but sparsely populated areas such as the Great Plains and Ukraine could now export grain far further from harvest to market without it rotting.
[1] The 1980s farm crisis in the USA was more localized as the strong dollar, high oil prices and the grain embargo against the Soviet Union conspired to raise farming costs and lower grain prices.
