IPY promotes constructive and respectful engagement with northern people, through community monitoring, through acknowledgement and protection of traditional knowledge, and through inclusion of northern people as valued partners in planning and conducting IPY and in evaluating and assessing IPY results and legacies. IPY researchers will focus on northern human health, particularly on impacts of pollution, contaminants and parasites in traditional foods, existing and emerging infectious diseases, chronic diseases, and unhealthy behaviors. Researchers will explore many facets of Arctic social systems, to determine resiliency to internal and external change and to develop adaptation and mitigation strategies. IPY investigations will include studies of unique uses of language, such as for intergenerational understanding of sea ice, studies of how legal systems protect the value and integrity of traditional knowledge, and economic and social assessments of the impacts and opportunities related to natural resource management and energy and transportation developments.
