Thanks everyone - some good comments and advice. If she keeps a diary or blog as Dan suggests then she will have a good reference to evidence of a productive year.
You may recall her asking TAS members to complete a survey re: wonkey vegetables. She tested the hypothesis that the public do not object to irregular veg that is out-croped and wasted despite the environmental and financial cost of production. Crops that are discarded required water, fertiliser and energy to plant,grow,harvest and sort - so chucking it away becuase it is the wrong shape is not clever. Her course included many other elements covered by various faculties ( economics, politics, geography and basic sciences).
Cattle and Timber are the key industries here and in the backround of EDF using many hydroelectric plants and some nuclear plants to generate electric. We are all encouraged to burn wood !! So I may get her cutting trees and splitting logs

. this should give her an insight into sustainable energy use.- if she sells some of my wonkey veg on the market then that will help her pay her way with us.
