In 2010, Russia was affected by a significant draught. Russia is a major producer and exporter of several agricultural commodities. As a result of the draught, Russia reduced some of its agricultural exports. In the context of the world supply/demand model for the affected agricultural commodities, we should observe:
Reduced supply and unchanged demand
Reduced supply and unchanged demand will be observed because agricultural goods are necessities and their demand is unaffected by natural calamaties. Only the supply will reduce.
