Abstract
The pressure exerted by a large city determines non-agricultural forms of land use in areas situated in its neighbourhood. Among the most alarming consequences of urban sprawl onto the surrounding areas are a steady and irreversible shrinkage of farmland and conflicts resulting from a mix of functions performed by the areas. This article describes the dynamics, scale and spatial differences of the process of taking agricultural land out of production in the Poznań agglomeration in the 21st century in terms of changes in the land-use pattern. In characterising the converted land, it also presents chief directions of its transformation, the regulations in force, and the resultant lack of full information about factual, and not only partial, conversions.
