Onderzoek naar het voorkomen van gemeentelijke land- en tuinbouwbedrijven, het beslag dat deze bedrijven op landbouwgrond leggen en de mate waarin de particuliere agrarische producent concurrentie wordt aangedaan

Notitie over de faktoren die het teruglopen beinvloeden van de bereidheid van partikuliere verpachters om in Nederland landbouwgrond te verpachten. Gekonkludeerd wordt dat er weinig te verwachten is van de komende wijzigingen in de pachtwet en dat de mogelijkheden de pachtprijs te verhogen beperkt zijn

After a survey of the development of the thinking in the Netherlands on the appraisal of agricultural lands, there is an analysis of the Ricardian view on the land rent. Ricardo's concept of rent proved to be tied to some specific suppositions. To him the size of population was endogenous. Mol placed the land rent in five different models, drawn up by him. In the first a legal fixation of the rent, which differed from the equilibrium rent, resulted in a deviation from the optimum size of the plant. An increase in prices of agricultural produce brought about a rise in land rent.

Changes in land use on farms at Hengelo were remarkably more frequent than was usually supposed in such areas. The larger farms had a general tendency to decrease in area, while the smaller farms tended to increase in area.

In olden times the diluvial sands of the southern Netherlands around the village nucleus formed widespread heaths, fens and bogs. On them the farmers had rights of grazing, and of digging peat and turf. In Saxon areas in the eastern Netherlands these lands became common property (marches or commons, Du. marken), while in the south, under the influence of French law, the land became municipal property.

Over the centuries they were reclaimed on a small scale; new settlements and villages grew up.

This paper serves three purposes. First, it gives a short introduction to the concept of sustainability in relation to land use. Since the Brundtland report it has become clear that sustainability is a dynamic concept that changes when conditions in society change. Moreover, it is easier to assess what is `unsustainable¿ than what is `sustainable¿. But that will not suppress the demand for sustainable developments.
