Sintesi	The von Thünen model is the founding theory of agricultural land use, explaining how the pattern of farming around a market emerges from transport costs and land rent. Set out by Johann Heinrich von Thünen in his 1826 work Der isolierte Staat, it imagines an isolated city on a uniform plain and shows that the rent a farmer can pay for land falls with distance to the market, so different crops and farming intensities sort themselves into concentric rings around the city. It is the earliest formal model in economic geography and the ancestor of bid-rent and urban land-use theory.	Bid-rent analysis is the urban-economics theory that explains how land rent and land use are organized by distance to the city centre. Developed by William Alonso in 1964, it represents each land use — commerce, industry, housing — by a bid-rent curve giving the maximum rent that use is willing to pay at each distance from the central business district. Because uses with steeper curves outbid others for central land, the observed rent is the upper envelope of all the curves, and the city sorts into concentric zones with the highest bidder winning each ring.
