Scotland's economic prospects have been downgraded by a forecasting group because of the ongoing crisis in the eurozone.
The Ernst & Young Scottish Independent Treasury Economic Model (ITEM) Group predicted growth of just 0.3% this year, down from the 1.1% forecast earlier this year.
The figure is lower than the projected growth rate for the UK as a whole and less than the 0.4% growth achieved by the Scottish economy last year.
Senior advisor Dougie Adams said a collapse of the euro would trigger a "significant" drop in output and employment in Scotland.
He said the country was also at risk because of the "lacklustre" recovery in the United States.
Mr Adams said: "The eurozone crisis is the most pressing risk to the Scottish economy.
"Our forecast is predicated on policymakers containing the crisis and averting a Greek exit from the single currency.
"The opposite scenario could trigger a chain of events that results in the collapse of the eurozone and leads to significant falls in output and employment in Scotland."
A Scottish Government spokesman said "clear and decisive leadership" in Europe was vital for the Scottish and global economies.
He said: "The Scottish Government has repeatedly called on the UK Government to follow a growth agenda to improve economic confidence, support businesses through improved access to finance and invest in the country's infrastructure.
"We continue to press the UK Government to fund a list of more than 30 'shovel ready' construction projects in communities across Scotland which would boost economic activity and jobs."
The report published by the group said that Scotland's economy "appears to have enjoyed little direct support from public sector output in the period since 2007".
It states that Gross Value Added by the Scottish public sector has increased by 1.6% since 2007, compared with growth of 4.6% in the UK as a whole.
ITEM expects overall manufacturing output to stagnate in Scotland this year, while construction is forecast to grow in line with the economy.
