Fears of "Brexit" are stark among the inhabitants of Blacklion in the Republic of Ireland and Belcoo in Northern Ireland, UK - two border villages that could be further separated if the United Kingdom opts to leave the European Union.

Only a gurgling stream separates the two villages, but Ireland's soft border could become a hard fact of life again if the United Kingdom leaves the European Union, the sovereignty-sharing bloc that has done much to blur the 95-year-old boundary.

Should a majority of British voters reject continued EU membership in the UK's June 23 referendum, Northern Ireland's nearly 500-kilometre (310-mile) frontier with the Irish Republic would become the only British land border with the 27-nation EU.

The closely intertwined residents of Belcoo in Northern Ireland and Blacklion barely 200 metres (218 yards) away in the republic would find themselves again in two diverging lands.

While some view that prospect as an opportunity, many more express dread at the thought.

Farmer Hugh Maguire, 60, whose Blacklion home rests barely inside the republic but whose nearby farm of sheep, cattle and hens lies in Northern Ireland, said he could not survive without EU subsidies.

Both communities are heavily dependent on EU funding. Agriculture is the top employer, and farms receive 329 euros (365 US dollars) per hectare of land from the EU's Single Farm Payment subsidy scheme in place since 2003, an annual payment exceeding 80,000 euros (90,000 US dollars) for Maguire's 241-hectare farm.

Few Northern Ireland farmers are confident that the British government, long a critic of EU farm subsidies, would maintain anything close to that level of state support.

Maguire estimates that EU payments provide two-thirds of his income while most of the rest requires open market access to livestock marts in the republic, where prices for spring lamb are stronger.

Behind the bar in 'Jack's Bar' in Belcoo in Northern Ireland, owner Paul Leonard and his son Stephen look likely to cancel each other's votes. The son favors staying in the EU, while the father is eyeing the exit.

"We've had so much tragedy and grief along the border area, that I just feel and hope that they will stay in. My fear is, I suppose, that this border will appear and will make everyday life difficult for everybody basically, because this is the main road from North to South, from Sligo, and we get a lot of traffic, a lot of tourists, and we've already suffered enough in this area, so we don't need to suffer anymore."
