He says the illegal invasion of the Ukraine by Russia and the recent covid pandemic had highlighted the critical need to ensure food security be made a top priority.
However the Galloway and West Dumfries MSP insists the SNP-Green coalition is not taking the matter seriously enough.
Speaking at Holyrood following a ministerial statement on future agriculture support, he said: “It is critical that we get food security right, due to the war in Ukraine.
“Little or no clarity has been provided on its agriculture bill proposals, and there is certainly not enough clarity in the statement.
“It does nothing to address the total lack of clarity with regard to payments, and it raises more questions than answers, in the vacuum of information that already exists.
“When will the Government prioritise our farmers and food security?”
However, Mairi Gougeon, Scottish Cabinet Secretary for Rural Economy, insisted the government had prioritised food security.
She said: “I understand the point about more detail, but we are committed to supporting the food producers in this country, including supporting them through the transition that I have set out the path towards today.”
