Ancient forms of agriculture could aid remote farming communities
British Ecological Society (BES)
Tossed up onto Scottish beaches by the tonne, seaweed is finding a place at the table thanks to the fashion for foraged food. But it could also play a vital role in returning acres of abandoned farmland in Scotland to production, according to new research presented at the British Ecological Society’s annual meeting in Edinburgh this week.
Ecologists from Scotland’s Rural College (SRUC) and the University of Edinburgh have been studying some of the UK’s remotest farming communities — the talamh dubh or ‘black land’ crofts on the east coast of North Uist.
Parallel ridges on hill sides here are remnants of old agricultural systems that the ecologists believe could be used to increase productivity on land now largely unused.
Crofting counties of the North West Highlands and Islands of Scotland make up 16% of land in the UK. Today, 375,000 people and five million sheep live there, yet the area imports 95% of its food. Between the 14th and 18th centuries, however, the area was home to over half a million people and was 90% self-sufficient in food.
To find out how best to return some of this land to production, the researchers combined modern science with traditional detective work, collecting community memories and Gaelic words, and poring over historical documents and old photographs.
According to lead author Dr Barbra Harvie of SRUC: “Most of this agricultural land has lain abandoned for more than 60 years and local knowledge of how to manage it is rapidly disappearing. By interviewing crofters, we are gleaning vital knowledge before it is lost forever.”
The studies also involve some hard graft, she says: “After researching historical crop rotations we have replicated these in the field by hand-digging ridges and hauling seaweed from the coast.”
