Run rig in the context of "List of islands of Scotland"

The Highland Clearances (Scottish Gaelic: Fuadaichean nan Gàidheal [ˈfuət̪ɪçən nəŋ ˈɡɛː.əl̪ˠ], the "eviction of the Gaels") were the evictions of a significant number of tenants in the Scottish Highlands and Islands, mostly in two phases from 1750 to 1860.

The first phase resulted from agricultural improvement, driven by the need for landlords to increase their income – many had substantial debts, with actual or potential bankruptcy being a large part of the story of the clearances. This involved the enclosure of the open fields managed on the run rig system and shared grazing. These were usually replaced with large-scale pastoral farms on which much higher rents were paid. The displaced tenants were expected to be employed in industries such as fishing, quarrying, or kelp harvesting and processing. Their reduction in status from farmer to crofter was one of the causes of resentment.

The Agricultural Revolution in Scotland was a series of changes in agricultural practice that began in the 17th century and continued in the 19th century. They began with the improvement of Scottish Lowlands farmland and the beginning of a transformation of Scottish agriculture from one of the least modernised systems to what was to become the most modern and productive system in Europe. The traditional system of agriculture in Scotland generally used the runrig system of management, which had possibly originated in the Late Middle Ages. The basic pre-improvement farming unit was the baile (in the Highlands) and the fermetoun (in the Lowlands). In each, a small number of families worked open-field arable and shared grazing. Whilst run rig varied in its detail from place to place, the common defining detail was the sharing out by lot on a regular (probably annual) basis of individual parts ("rigs") of the arable land so that families had intermixed plots in different parts of the field.
