Less government regulation is needed to encourage healthy competition to help London farmers compete on the world stage.
The Vice President of the National Farmers Union Guy smith described 2014 as “a story of swings and roundabouts” for farmers in the capital.
He said while the weather has been good, prices have been driven down by a glut of produce.
Speaking of 2015, Mr Smith says farming is becoming increasingly volatile and requires a speculative business approach.
He calls for the government to reduce regulation in farming.
He told London Live: "We're convinced our standards are good and we don't need need additional regulation and when you over-regulate your farmers, you simply make them less competitive and you start importing more and more food."
Mr Smith also challenged supermarkets to "walk the walk" and to use local produce from local farmers.
