Summary of Results


For nomadic pastoralists mobility is a key strategy for buffering environmental variation. Fragmentation of rangelands—through e.g. land tenure shifts or changes in use—dissects natural systems into spatially isolated parts restricting the movement of both people and animals. In short, fragmentation limits access to key resources that vary over time and space. The overall objective of this project is thus to assess to what degree fragmentation, through limiting movement, affects long-term viability for pastoralists under different climate scenarios by the use of computer simulations (agent based modelling). The main results of this project are (1) the development of livestock-grass interactions implemented in a model setting. Fragmentation and climate scenarios are being developed; (2) two presentations reviewing the effects of fragmentation comparatively (see list below); and (3) submission of the application “Fragmentation, density dependency and climate change—Saami reindeer husbandry on the brink” to MILJØFORSK in September 2015, extending the framework of the current project.
