Is it just these 4 items or are any number of non-monetary items
acceptable - building/fire wood, practical work, potatoes.... I.e. can
someone come and say, sorry I do not have rice, but instead I brought
potatoes?

If former, maybe defining the four items as a separate "currency" each
will be the solution? You then operate 5 separate currency accounts -
rice, sugar, beans maize, money. 

If latter, it seems that you employ some sort of equivalency  payment,
each of which, even if it comes in non-monetary form has for you a -
presumably well defined "1kg rice = 500g sugar = £1" -  monetary value.
