![]() ![]() Complex commodity chains link production and consumption of agricultural products.Large-scale commercial agricultural operations are replacing small family farms.Intensive and extensive farming practices are determined in part by land costs (bid-rent theory).Agricultural production regions are defined by the extent to which they reflect subsistence or commercial practices (monocropping or monoculture).The Green Revolution had positive and negative consequences for both human populations and the environment.The Green Revolution was characterized in agricultural by the use of high-yield seeds, increased use of chemicals, and mechanized farming.New technology and increased food production in the Second Agricultural Revolution led to better diets, longer life expectancies, and more people available for work in factories.Patterns of diffusion, such as the Columbian Exchange and the agricultural revolutions, resulted in the global spread of various plants and animals.Early hearths of domestication of plants and animals arose in the Fertile Crescent and several other regions of the world, including the Indus River Valley, Southeast Asia, and Central America.Rural survey methods include metes and bounds, township and range and long lot.Rural settlement patterns are classified as clustered, dispersed, or linear.Specific agricultural practices shape different rural land-use patterns. ![]() Extensive farming practices include shifting cultivation, nomadic herding, and ranching.ĥ.2 Settlement Patterns and Survey Methods.Intensive farming practices include market gardening, plantation agriculture, and mixed crop/livestock.Agricultural practices are influenced by the physical environment and climate conditions, such as the Mediterranean climate and tropical climates. ![]() 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.FIVE: AGRICULTURE & RURAL LAND-USE PATTERNS & PROCESSES 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. 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. #AP HUMAN GEOGRAPHY METES AND BOUNDS SERIES# interior.Ī system of land surveying east of the Appalachian Mountains. ![]() It is a system that relies on descriptions of land ownership and natural features such as streams or trees. 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.
