More than 4,000 jobs in Carmarthen West and South Pembrokeshire rely on farming, Simon Hart MP learned during a special event to Back British Farming.
Farming in the constituency contributes £30.6 million to the local economy - on top of the safe, affordable food farmers produce and the British countryside they maintain.
In addition to its role producing food, farming also supports the work of other industries, such as vets, solicitors, surveyors and feed merchants.
The Back British Farming event in Westminster was held by the National Farmers' Union (NFU) as a rallying call to MPs to support farming – during a particularly crucial period for British farming as the Brexit negotiations begin.
Mr Hart said: "There are so many worthy reasons to support British farmers: they are responsible for securing our fantastic British food supply, looking after our world-renowned countryside and sustaining a dynamic rural economy. That is why I am proud to wear the NFU's Back British Farming pin badge in Parliament today.
"These reasons are why I have pledged to Back British farming in Westminster and to ensure our decisions in Parliament reflect the strategic importance of British food and farming to the nation.
"As one of the sectors that will be most affected by Britain's withdrawal from the EU, it is critical that as politicians we create the right regulatory environment to ensure our farmers can continue to provide the safe and affordable food that the public trust and demand."
