Arctic transportation routes - roads, shipping and pipelines
Hugo Ahlenius, UNEP/GRID-Arendal
Land infrastructure represents a fragmentation of the natural ecosystems, splitting up expanses of tundra and taiga - and creates a disturbance in the form of traffic. In addition, it promotes development of side roads, houses and facilities. Shipping doesn't present a threat in the same way, but there are risks related to goods that could present a hazard for the environment, such as oil.
