The Role of Salmon in Middle Snake River Human Economy: The Hetrick Site in Regional ContextsManning, Cassandra R. 01 January 2011 (has links)
On the Columbia Plateau, the origin of the Winter Village Pattern has long been a focus of research. Intensification of resources such as salmon, roots, and local aquatic resources is often cited as the cause of declining mobility. To address this question in the middle Snake River region, I have re-analyzed fish remains from the Hetrick site (10WN469; Weiser, ID), with occupations spanning the Holocene. Expectations from foraging theory and paleoclimate data are used to address whether salmon and other fish use changed over time and if such changes are correlated with the development of the Winter Village Pattern. The results of my research indicate that there is no correlation between the timing of increased salmonid use at the Hetrick site and paleoclimatic change or the earliest evidence for the Winter Village Pattern. Further, these results are very similar to patterns of fish use seen at other sites on the Snake River, particularly those from the Early and Middle Holocene.

Public Perception of Health Risks Related to Climate Change in Broward County, FloridaUnknown Date (has links)
Scholars agree that global climate change is a major threat to the physical
environment, affecting all aspects of life on the planet. However, the general public do
not feel that climate change is a major risk or threat, especially to humans. It is important
to understand the public’s perception and opinions of climate change as it affects and
influences the creation and passing of climate change adaptation and mitigation policies.
Specifically, little is known about public perceptions in regards to the greater health risk
imposed by global climate change. This study examines the public's perception of health
risks related to climate change in Broward County, Florida by using mixed methods. An
online survey was conducted along with in-person interviews with the general public and
a physician. The study found majority of respondents to believe climate change affects
health, but lacked an understanding of how it is harmful to their health. It also found that
gender affects their perceptions and political ideology appears to have an effect, but the
effect of socioeconomic status on their perceptions were unable to be determined at this time. Broward is just developing policies to adapt and mitigate the health effects of
climate change. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Climate change in the Western Cape : a disaster risk assessment of the impact on human healthLouw, E. J. M. 12 1900 (has links)
Thesis (DPhil (Geography and Environmental Studies))—University of Stellenbosch, 2007. / Background
The Disaster Management Act (Act 57 of 2002) instructs a paradigm shift from preparedness,
response and recovery towards risk reduction. In order to plan for and mitigate risks, all spheres of
government must firstly assess their hazards, vulnerabilities, capacity to cope and therefore risks.
Studies in this regard, in South Africa, have however only focussed on current risks. Climate
Change has now been accepted by leading international studies as a reality. Climate change can
impact upon many aspects of life on earth. Studies to quantify the impact of climate change on
water resources, biodiversity, agriculture and sustainable development are steadily increasing, but
human health seem to have been neglected. Only general predictions, mostly regarding vector-borne
disease and injury related to natural disasters are found in literature. Studies in South Africa have
only focussed on malaria distribution. Most studies, internationally and the few in South Africa,
were based on determining empirical relationships between weather parameters and disease
incidence, therefore assessing only the hazard, and not the disaster risk.
Methodology
This study examines the impact of climate change on human health in the Western Cape, within the
context of disaster management. A qualitative approach is followed and includes:
· A literature overview examining predicted changes in climate on a global and regional scale,
· A discussion on the known relationships and possible impacts climate change might have on
human health,
· A disaster risk assessment based on the status quo for a case study area, the Cape Winelands
District Municipality,
· An investigation into the future risks in terms of health, taking into account vulnerabilities and
secondary impacts of climate change, resulting in the prioritisation of future risks.
· Suggestions towards mitigation within the South African context.
Results
The secondary impacts of climate change were found to have the larger qualitative impact. The
impact of climate change on agriculture, supporting 38% of the population can potentially destroy
the livelihoods of the workforce, resulting in poverty-related disease. Other impacts identified were injuries and disease relating to temperature, floods, fire and water
quality.
Conclusion
Risk is a function of hazard, vulnerability and capacity to cope. The impact of an external factor on
a ‘spatial system’ should be a function of the impacts on all these factors. Disasters are not
increasing because of the increase in the frequency of hazards, but because of the increasing
vulnerability to hazards. This study illustrated that the major impacts of the external factor could
actually be on the vulnerabilities and the indirect impacts, and not on the hazard itself. Climate
change poses a threat to many aspects of the causative links that should be addressed by disaster
management, and its impacts should be researched further to determine links and vulnerabilities.
This research also illustrates that slow onset disasters hold the potential to destroy just as much as
extreme events such as Katrina, Rita or a tsunami. It also reiterates that secondary impacts may not
be as obvious, but are certainly not of secondary importance.
