Jordbruksareal som går ut av drift gror etterhvert igjen med busker og kratt. Gjengroing medfører ikke bare tap av viktige arealressurser, men også kulturelle verdier og biologisk mangfold. Laserteknologi kan gjøre det mulig å registrere framvekst av busker og trær allerede i et tidlig stadium. Dette gir muligheter til å sette i gang tiltak for å motvirke denne utviklingen.

Norway has only 3% farmland, and much of it is under strong pressure from urban development. There is a conflict of interest whether to prioritise farmland protection or minimised need for person transport when developing new areas. However, as transport has started to become increasingly climate- friendly, we argue that weighing up interests among different land use types and within farmland is advancing. To illustrate the potential of land resource and soil quality maps for that purpose, we have carried out a GIS analysis within a radius of 1 km around all railway stations in Oslo and Akershus Counties. The analysis reveals large areas of farmland close to a number of stations and a generally high share of very good soil quality. We suggest different respects for weighing up farmland protection among and within different locations, and we envision a transition from competition between urban development and farmland protection towards a partnership.
