Agriculture and Rural Land Use: Origins, Systems, and Landscapes
Core concepts
Know the Neolithic Revolution and agricultural hearths (Fertile Crescent, Andes, Mesoamerica, Ethiopia, Southeast Asia). Distinguish subsistence from commercial agriculture, intensive from extensive, and shifting cultivation (slash-and-burn, tropical, with long fallow) from pastoral nomadism (arid, herding). Learn von Thünen's model: land use rings around a market, with perishable and high-value goods near the center and bulky, low-value goods farther out, driven by land rent and transport cost. Understand the Green Revolution (high-yield varieties, irrigation, fertilizer; uneven benefits), genetically modified organisms, and sustainable agriculture (crop rotation, organic methods, conservation). Bid-rent reasoning also applies to rural land, but von Thünen is the classic. Rural settlement patterns-clustered, dispersed, linear-and cadastral systems (metes and bounds, township and range, long lot) shape the cultural landscape. Commodity chains and food deserts connect agriculture to economy and cities.
Traps and a worked example
Do not place intensive agriculture far from markets; do not confuse shifting cultivation with pastoral nomadism; do not assume the Green Revolution eliminated hunger-distribution and access matter. Cadastral patterns are often tested through landscape descriptions.
Worked example: A dairy farmer near a city and a wheat farmer farther away both face the same market. Under von Thünen, dairy (perishable, high value per acre) locates near the market; wheat (bulky, less perishable, lower value per acre) locates farther out-matching the model's land-rent logic.
