Determining Water Requirements In Turfgrass Systems, Tyler Quinn Carr
Determining Water Requirements In Turfgrass Systems, Tyler Quinn Carr
Graduate Theses and Dissertations
Turfgrass lawns are commonly utilized for home and commercial applications because of the aesthetic, environmental, and recreational benefits grasses provide, but many people perceive turfgrass as solely an aesthetic benefit that requires significant water inputs. It is important to identify and use turfgrass cultivars that have known drought tolerance, and also fine-tune and throughout development. A series of field experiments were conducted to determine the water requirements of turfgrass lawn systems with the following objectives: 1) investigate differences in chronic drought resistance and irrigation recommendations among cultivars of Kentucky bluegrass (Poa pratensis L.) and tall fescue (Festuca arundinacea Schreb.) 2) …
Rangeland Management During Drought: Assessing Social-Ecological And Cognitive Indicators Of Ranchers’ Adaptive Capacity, Tonya Haigh
School of Natural Resources: Dissertations, Theses, and Student Research
Rangeland managers face challenges to adapt to climate extremes, and research is needed on how to support their adaptive capacity for managing climate risk. This study evaluates adaptive capacity using an integrated vulnerability and resilience conceptual model and three cognitive behavioral models. Overarching research questions focus on the relationship between protective action and impacts and the best predictors of taking action in response to drought. Three studies address these questions, using quantitative data collected from two post-drought surveys of rangeland-based livestock managers in the Northern Great Plains of the U.S. The studies find evidence of the roles of social-ecological sources …
Drought Impacts Assessment In Brazil - A Remote Sensing Approach, Denis Mariano
Drought Impacts Assessment In Brazil - A Remote Sensing Approach, Denis Mariano
School of Natural Resources: Dissertations, Theses, and Student Research
Climate extremes are becoming more frequent in Brazil; studies project an increase in drought occurrences in many regions of the country. In the south, drought events lead to crop yield losses affecting the value chain and, therefore, the local economy. In the northeast, extended periods of drought lead to potential land degradation, affecting the livelihood and hindering local development. In the southern Amazon, an area that experienced intense land use change (LUC) in the last, the impacts are even more complex, ranging from crop yield loss and forest resilience loss, affecting ecosystem health and putting a threat on the native …
Evaluating Future Reservoir Storage In The Rio Grande Using Normalized Climate Projections And A Water Balance Model, Nolan T. Townsend
Evaluating Future Reservoir Storage In The Rio Grande Using Normalized Climate Projections And A Water Balance Model, Nolan T. Townsend
Earth and Planetary Sciences ETDs
We develop and implement new tools for assessing the future of surface water supplies in downstream reaches of the Rio Grande, for which Elephant Butte Reservoir is the major storage reservoir. First, a normalization procedure is developed to adjust natural Rio Grande streamflows simulated by dynamical models in downstream reaches. The normalization accounts for upstream anthropogenic impairments to flow that are not considered in the model, thereby yielding downstream flows closer to observed values and more appropriate for use in assessments of future flows in downstream reaches. The normalization is applied to assess the potential effects of climate change on …
Conducting A Drought-Specific Thira (Threat And Hazard Identification And Risk Assessment): A Powerful Tool For Integrating All-Hazard Mitigation And Drought Planning Efforts To Increase Drought Mitigation Quality, Elliot Wickham, Deborah J. Bathke, Tarik Abdel-Monem, Tonya K. Bernadt, Denise Bulling, Lisa M. Pytlikzillig, Crystal J. Stiles, Nicole Wall

In the United States, drought is the second costliest natural disaster, which leads to the need for increased drought mitigation efforts over time. However, drought planning has lagged behind other hazard mitigation efforts, which is likely due to the lack of a national drought planning policy. Although the Federal Emergency Management Agency (FEMA) requires all jurisdictions have a hazard mitigation plan (HMP) to receive pre-disaster mitigation funds, drought has only recently been a requirement in HMPs. In 2012, Nebraska witnessed its worse drought in recent history, which exposed the gaps in drought planning effectiveness at all jurisdictional levels. To address …
