Back to the Land is in Yorkshire, meeting a father-and-son team who own the first and only caviar farm in the UK that harvests sturgeon eggs ethically and humanely. After dad John invested his entire pension pot in the business, Kate is with them at a crucial point of egg harvest and as they embark on their own breeding programme which, if successful, could make or break the business.

Kate also meets a family that have diversified into growing hemp on an industrial scale and even built their farm house with it, showing that hemp can be a sustainable and effective building material. We join two ex-Londoners who moved to the country to farm rare-breed pigs and created an honest sausage company using only the best cuts of their pigs, all of which are raised outdoors and have over double the life span of commercially farmed pigs.

And we meet a lady who crafts the famous Whitby jet in its raw form, then polishes, shapes and works it into silver and gold jewellery which she smiths herself. The solid black gem was once mined and a major part of the local economy throughout the Victorian era. Show less
