Whiskey is for drinking - water is for fighting over: population growth, infrastructure change, and conservation policy as drivers of residential water demand

Description

As urban populations grow, water managers are becoming increasingly concerned about water scarcity. Water managers once relied on developing new sources of water supply to manage scarcity but economically feasible sources of unclaimed water are now rare, leading to an increased interest in demand side management. Water managers in Las Vegas, Nevada have developed innovative demand side management strategies due to the cities rapid urbanization and limited water supply. Three questions are addressed. First, in the developed areas of the Las Vegas Valley Water District service areas, how did vegetation area change? To quantify changes in vegetation area, the Matched Filter Vegetation Index (MFVI) is developed from Mixture Tuned Match Filtering estimates of vegetation area calibrated against vegetation area estimates from high-resolution aerial photography. In the established city core, there was a small but significant decline in vegetation area. Second, how much of the observed decline in per capita consumption can be explained by Las Vegas land cover and physical infrastructure change that resulted from extensive new construction and new use of water conserving technology, and how much can be attributed to water conservation policy choices? A regression analysis is performed, followed by an analysis of three counter-factual scenarios to decompose reductions in household water into its constituent parts. The largest citywide drivers of change in water consumption were increased water efficiency associated with new construction and rapid population growth. In the established urban core, the most significant driver was declining vegetation area. Third, water savings generated by a conservation program that provides incentives for homeowners to convert grass into desert landscaping are estimated. In the city core, 82 gallons of water are saved in June for each square meter of landscape converted in the first year after conversion, but the savings attenuate to 33 gallons per meter converted as the landscape ages. Voluntary landscape conversion programs can generate substantial water savings. The most significant result is that the most effective way to ensure long term, sustainable reductions in water consumption in a growing city without changing water prices is to support the construction of water efficient infrastructure.

The Economic Effects of the Las Vegas Golden Knights in Nevada

Description

Las Vegas, Nevada has been considered the "Entertainment Capital of the World" bolstering what seems like endless possibilities and attractions for those who come looking to have a good time. From the many storied casinos that line The Strip, to replicas of wonders of the world, and the countless attractions the city hosts such as the world-renowned shows and other blockbuster events, Vegas seems to have it all. However, one thing seems to be missing \u2014 professional sports. This project highlights the introduction of Las Vegas' first ever professional sports franchise, the Golden Knights, along with the journey it took to get there. Beginning with origins of professional hockey and the foundation of the NHL in 1927, the League has grown substantially in size that spans over 19 states, from coast to coast, across the country. From the NHL's first expansion in 1967, the league has witnessed immense growth through the influence of broadcasting rights and seen through increased television ratings, in-game attendance numbers, and youth hockey registration numbers in markets throughout the United States. The growth and promotion of hockey culture in regions outside the North and Northeastern part of the nation have led to the recent expansion of hockey into Las Vegas. This thesis covers the steps in which the new Vegas franchise was formed, in addition to the key factors that led to the team's incredible inaugural season success which has marked them the most successful expansion team ALL North American sports history. Finally, after displaying the contributions the Golden Knights have had on the ice, this thesis illustrates the impact the team has made off the ice both for the Las Vegas economy and the local community. Through the construction of Vegas' state of the art arena, the franchise's ticket and merchandise sales, the media value and attention the team has brought to Las Vegas, and the increase in jobs created for the city, the Golden Knights have been generating hundreds of millions of dollars for Las Vegas. As the city's first professional sports franchise, the Golden Knights have truly become a successful addition to the "Entertainment Capital of the World," and to the NHL itself.

Does the Spatial Arrangement of Urban Landscape Matter? Examples of Urban Warming and Cooling in Phoenix and Las Vegas

Description

This study examines the impact of spatial landscape configuration (e.g., clustered, dispersed) on land-surface temperatures (LST) over Phoenix, Arizona, and Las Vegas, Nevada, USA. We classified detailed land-cover types via object-based image analysis (OBIA) using Geoeye-1 at 3-m resolution (Las Vegas) and QuickBird at 2.4-m resolution (Phoenix). Spatial autocorrelation (local Moran’s I ) was then used to test for spatial dependence and to determine how clustered or dispersed points were arranged. Next, we used Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data acquired over Phoenix (daytime on 10 June and nighttime on 17 October 2011) and Las Vegas (daytime on 6 July and nighttime on 27 August 2005) to examine day- and nighttime LST with regard to the spatial arrangement of anthropogenic and vegetation features. Local Moran’s I values of each land-cover type were spatially correlated to surface temperature. The spatial configuration of grass and trees shows strong negative correlations with LST, implying that clustered vegetation lowers surface temperatures more effectively. In contrast, clustered spatial arrangements of anthropogenic land-cover types, especially impervious surfaces and open soil, elevate LST. These findings suggest that city planners and managers should, where possible, incorporate clustered grass and trees to disperse unmanaged soil and paved surfaces, and fill open unmanaged soil with vegetation. Our findings are in line with national efforts to augment and strengthen green infrastructure, complete streets, parking management, and transit-oriented development practices, and reduce sprawling, unwalkable housing development.
