How Agro-Pastoralists Adapt To Climate Change In The Algerian Steppe?, Slimane Bédrani, Mohamed El Amine Benhassine

IGC Proceedings (1997-2023)

The Algerian steppe grasslands cover about 30 million ha located between the 100 and 400 mm isohyets. It feeds about 15 to 23 million sheep and goats, depending on the year (MARA 1974). To assist agro-pastoralists plan for future we wanted to know:

• What perceptions do different pastoralists and agro-pastoralists have of climate change?
• Have these land users changed the way they are man-aging their livestock and crop production enterprises? and,
• How do changes adopted differ pastoralists and agro-pastoralists?

The Effects Of Climate Science Literacy And Cultural Polarization Around Climate Change Risk Perception, Gabriel R. Young, Helen R. Neill

Graduate Research Symposium (GCUA) (2010 - 2017)

Science communicators have struggled to provide meaningful information about climate change due to the complex nature of the problem and the polarized political and media landscapes, and yet, a well informed public is a crucial element to both public acceptance and policy initiatives aimed at climate change mitigation. Current literature suggests that scientific literacy actually increases cultural polarization around the issue of climate change (Kahan, 2012). This study adds to the literature by testing the hypothesis that climate change risk perception is more heavily tied to climate science literacy than general science literacy when controlling for cultural worldviews. We use …

Investigating Perspectives Of Rural Nevadans On Climate Change Solutions, Tricia Dutcher

Graduate Research Symposium (GCUA) (2010 - 2017)

Rural perspectives are important for the issue of climate change. Rural areas are high concentrations of active voters who deny the problem of anthropogenic climate change. Rural residents also face decisions about inviting large, utility scale renewable energy developments in their areas. This research examines rural Nevadan’s perspectives on climate change to offer insights about the relationship between climate change perceptions and communication strategies. The research offers policy implications that address context specific issues, solution-oriented dialogue, and interest matching to mitigate anthropogenic climate change.

Has Recent Climate Change Caused A Genetic Bottleneck In A Sierra Nevada Population Of The Bushy-Tailed Woodrat?, Mitchell Gritts, Angela D. Hornsby, Majorie D. Matocq

Festival of Communities: UG Symposium (Posters)

Many montane species respond to climate change by shifting their range upslope as temperatures at lower elevations increase. An elevation range shift causes a range contraction that may result in a population bottleneck. Joseph Grinnell surveyed the fauna along the Yosemite transect from 1914 to 1920. In 2003 Craig Moritz and his colleagues began to resurvey the Yosemite transect to assess the faunal change during a century of climate change. The bushy-tailed woodrat suffered severe range contraction and population bottleneck between the two surveys. I will use evolutionary models to determine if the population has suffered a genetic bottleneck.

Similarity Of Climate Change Data For Antarctica And Nevada, Corbin Benally, Shahram Latifi, Karletta Chief

Undergraduate Research Opportunities Program (UROP)

The correlation between temperature and carbon dioxide concentration in the past one hundred years is studied. Separate graphs containing data from Vostok, Antarctica and the Mojave desert/mountain west (Nevada region) are presented. Using data obtained from these graphs, an attempt is made to explain the results and investigate the similarity of these results for Antarctica and Nevada. The importance of this study lies in the fact that if data show the same trend in the two regions, many findings for climate change in Antarctica may readily be validated and employed for Nevada.

Water Source Partitioning For Shrubland Transpiration Using Innovative Field Methods, Dale A. Devitt, Michael Young, Matthew S. Lachniet, Jeremy Koonce, Amanda Wagner, Brian M. Bird, J. Healey

2010 Annual Nevada NSF EPSCoR Climate Change Conference

37 PowerPoint slides Convener: Franco Biondi, UNR & Michael Young, DRI Session 4: Ecological Change and Water Resources Abstract: -Climate change models predict a decline in precipitation over the next few decades throughout much of the southwest. -Such change has the potential to shift water uptake dynamics of phreatophytes -If groundwater pumping also occurs, the impact of climate change could be exacerbated. -A better understanding of the forces that drive the coupling and decoupling of phreatophytes to groundwater is needed.

Session 9 - The Century Of Living Dangerously, Part Ii: Confronting Uncertainty, R. J. Bogumil

International Symposium on Technology and Society

Probabilistic risk assessment (PRA) methodological limitations as well as environmental application-specific features confound much needed objective analysis and hope for equitable remediation of anthropogenic climate change. Issues addressed include: risk subjectivism, the difficulty of mathematical and computer model prediction-validity assessment associated with chaotic system dynamics, as well as standards of scholarship and the obstacle to societal reform posed by commercial, consumer-driven mass-media journalism.
