HARC Online Workshops 2002 | Background

Humans and Arctic Hydrology:
An online workshop to develop a human
dimensions component for Arctic-CHAMP

April 15-17, 2002
Moderators: Larry Hinzman, University of Alaska Fairbanks - Larry Hamilton, University of New Hampshire

Support: Henry Huntington, HARC SMO

Participant list is here.

Purpose
In the Arctic as elsewhere, the flow of water has a great influence on humans. The hydrological cycle is the process by which water (including ice and snow as well as the liquid form) circulates through the Arctic system. Evaporation leads to clouds, from which comes precipitation. Rain affects plant growth and contributes to rivers, lakes, and wetlands. Snow blankets the landscape, and snowmelt causes a huge pulse of freshwater in terrestrial and aquatic systems. Ice and permafrost shape the landscape and seascape as well. Feedbacks among all these processes make detecting and anticipating change a complex undertaking. Nonetheless, the implications of hydrological changes for humans may be critical.

The purpose of this workshop was to identify and discuss the types of research projects that investigate the links between humans and hydrology in the Arctic. Many of these links have been identified (see Table 5-2, below, from Vörösmarty et al., 2001). The CHAMP initiative presents a great opportunity to create a strong human dimensions component in hydrology research, closely linked with research on the physical and biological aspects of the hydrological cycle. By identifying research ideas at the project level, the workshop can provide ideas for proposals to the HARC initiative at NSF.

Format
The workshop followed the same format as previous HARC online workshops. The two moderators started and guided the discussion. The forum was open for the entire three-day period so comments could be posted at the convenience of each participant.

Opening Questions
To get the workshop started, we asked the following questions:
    1. Societal Vulnerability and Impacts: What types of studies can determine societal vulnerability and impacts, in the following areas, to changes in the hydrological cycle and related processes?
    • Infrastructure (industrial development, community location & facilities, etc.)
    • Transportation
    • Fisheries
    • Other economic activities (e.g., tourism)
    • Traditional hunting, fishing, gathering
    • Health
    • Combined vulnerability

    2. Human Influences on Hydrologic Processes: What types of studies can determine human influences on the hydrological cycle and on the physical and biological processes that are controlled by hydrology?
    • Infrastructure and development
    • Water use
    • Pollution and disturbance
    • Landscape change (e.g., from reindeer overgrazing)
    • Combined impacts

    3. Implications of Hydrologic Change: In what other ways are changes in hydrologic processes in arctic regions likely to affect the individual, the community, industry, and society (both in and outside the Arctic), and how can these be studied?
