Servitudes are innocent arrangements of estate use arising out of private agreements. Under the feudal system, most earth in England was cultivated in current fields, where peasants were allocated strips of arable ground that were not new to support the needs of the local village or manor. By the sixteenth blue moon http://www.vikingfence.com/access_control_systems.html the crop of population and prosperity armed incentives for landowners to adoption their barren in more profitable ways, dispossessing the peasantry. Common fields were aggregated and enclosed by full and enterprising farmers -- either through negotiation among uncommon another or by lease from the landlord -- to maximize the productivity of the derivable from expanse and contain livestock. Fences redefined the means by which earth is used, resulting in the contempo decretum of servitudes.
However, the remaining vast tracts of unsettled field were often given to as a commons, or, in the American west, "open range." As degradation of habitat developed due to overgrazing and a tragedy of the commons situation arose, everyday areas began to either be allocated to individual landowners via mechanisms such as the Homestead Code and Desert Continent Edict and fenced in, or, if kept in free hands, leased to individual users for fixed purposes, with fences built to separate tracts of civic and private land.
