rationing

noun

A ration.
Controlled distribution of scarce resources such as food or fuel; used typically in wartime.
“The drastic rationing of paper enforced by the paper control, has made it necessary for us to adapt ourselves to the altered conditions.”
“After petrol rationing ended in 1952, the BTC was aware that more swingeing cuts had to be made, and a sinister message was conveyed by the loss of the meandering 38-mile route from Blisworth to Stratford-upon-Avon in April 1952, and the 25-mile Abergavenny-Merthyr Heads of the Valleys line in January 1958.”
