  • Towards Environmental Justice for a Changing Arctic and Its
    TOWARDS ENVIRONMENTAL JUSTICE FOR A CHANGING ARCTIC AND ITS ORIGINAL PEOPLES: CONTESTING THE COLONIAL ‘POLITICS OF NATURE’ OF OFFSHORE DRILLING IN ALASKA by ALANA SHAW (Under the Direction of HILDA E. KURTZ) ABSTRACT Rising temperatures in the Arctic are spawning a new era of industrial interest in this region. While development projects like the Arctic offshore drilling program present the opportunity for much-needed regional economic growth and employment they also represent a significant risk to the traditional subsistence way of life that has been pursued by the Iñupiat on Alaska’s North Slope for millennia. The difficulties that the Iñupiat now face in terms of finding ways to balance their economic and cultural needs within a changing Arctic have only been exacerbated by a colonial ‘politics of nature’, which has both historically as well as currently worked to limit their abilities to effectively advocate for their own self-determined lives and futures as a sovereign people. Within the offshore drilling program, this has meant that the concerns and perspectives of the Iñupiat have been marginalized by its decision-making processes because of the intellectual superiority long afforded to Western ways of knowing, which is itself the product of a socially constructed divide between culture and nature that is upheld by dominant society. Such contemporary injustice is further compounded by those ‘well-meaning’ acts of forced cultural assimilation such as the Alaska Native Claims Settlement Act of 1971, which has profoundly altered the economic and political positioning of the Iñupiat in ways that have left them vulnerable to the siren call of offshore development.

  • The Juneau Icefield Frequires Skill and the Right Equipment
    This image is a Landsat satellite image acquired on Julie 27,1992. The image is based on green, red and near infrared light reflected from the earth's surface. Healthy vegetation reflects strongly in the infraredji band and is depicted in varyiing shades of red. Th| infrared band is also useful for delineating sediment plumes from glacier-fed streams and rivers. Ice climbing in the Juneau Icefield frequires skill and the right equipment. FEE DEMO This brochure is produced from funds collected through the Recreation Fee Demonstration Project. Authorized by Congress, this national pilot program allows federal land management agencies to collect user fees which provide new enhancements and improve existing services. Fees for this brochure are collected in partnership with helicopter tour operators for the Juneau Icefield, which is located in the Tongass National Forest.
