Settlement pattern: Low population density, planned grid iron pattern, linear settlements, hierarchical pattern of small farms, small towns and occasionally a large service town.

Increased mechanisation Increased productivity per person Consolidation of farm units Out migration Spiral of decline of towns and villages

Failed soya bean crop 2006 due to drought. In October 2006 USA Today reported: 7 years of drought on Great Plains rd warmest on record - extreme lack of rain. Affecting grazing on the range and HEP as well as crops.

land Extensive commercial farming: The Prairies Land holdings enormous - very flat, so large fields. Black earth soils rich in humus. Mechanisation means holdings have been consolidated.

land Extensive commercial farming: The Prairies capital Amount of capital inputs high (tractors, ploughs, harvesters). High use of artificial pesticides and herbicides (planes for spraying). Improved seeds - in some areas GM crops now widespread.
