Land Office Survey abandoned the technique in favor of the rectangular survey system.ĭistinct regional approach to land surveying found in the Canadian Maritimes, parts of Quebec, Luisiana, and Texas whereby land is divided into narrow parcels stretching back from rivers, roads, or canals Because of the imprecise nature of metes and bounds surveying, the U.S. It is a system that relies on descriptions of land ownership and natural features such as streams or trees. interior.Ī system of land surveying east of the Appalachian Mountains.
The system divides land into a series of rectangular parcels.Ī rectangular land division scheme designed by Thomas Jefferson to disperse settlers evenly across farmlands of the U.S. The development of higher-yield and fast-growing crops through increased technology, pesticides, and fertilizers transferred from the developed to developing world to alleviate the problem of food supply in those regions of the globe.Ĭrops that carry new traits that have been inserted through advanced genetic engineering methodsĪlso called the Public Land Survey, the system was used by the US Land Office Survey to parcel land west of the Appalachian Mountains. A process of spatial competition allocates various farming activities into rings around a central market city, with profit-earning capability the determining force in how far a crop locates from the marketĬurrently in progress, the Third Agricultural Revolution has as its principal orientation the development of Genetically Modified Organisms (GMO's) See shifting cultivation cultivation of crops in tropical forest clearings in which the forest vegitation has been removed by cutting and burningĭovetailing with and benefiting from the Industrial Revolution, improved methods of cultivation, harvesting, and storage of farm produceĪ model that explains the location of agricultureal activities in a commercial, profit-making economy. Self sufficient agriculture that is small scale and low technology & emphasizes food production for local consumption, not tradeĬultivation of crops in tropical forest clearings in which the forest vegitation has been removed by cutting and burning Genetic modification of an animal such that it is rendered more amenable to human control
