What do you think of when you hear the word sustainable? I know I think of flowing rivers, green fields and trees, but I have never associated the word with financial sustainability until recently. And that is probably the most important point of all.

There are three spokes in the sustainability wheel – financial, environmental and social. Sustainable production is a popular phrase at the moment, and it seems to have struck a chord with consumers who are becoming increasingly concerned about where their food comes from.
