For example, since 2000 wheat crop varied within the range of 9 million tonnes (in 2000/01) and 23 million tonnes (in 2011/12). Building an elevator to store around 10 000 tonnes costs at least USD 3 million, and between USD 5 million and USD 10 million for a 20 000-tonne capacity elevator. It later fell to USD 60-80 per tonne as evidence of a bumper crop became clearer.
