Long-Term, Gridded Standardized Precipitation Index For Hawai‘I, Matthew P. Lucas, Clay Trauernicht, Abby G. Frazier, Tomoaki Miura
Long-Term, Gridded Standardized Precipitation Index For Hawai‘I, Matthew P. Lucas, Clay Trauernicht, Abby G. Frazier, Tomoaki Miura
Geography
Spatially explicit, wall-to-wall rainfall data provide foundational climatic information but alone are inadequate for characterizing meteorological, hydrological, agricultural, or ecological drought. The Standardized Precipitation Index (SPI) is one of the most widely used indicators of drought and defines localized conditions of both drought and excess rainfall based on period-specific (e.g., 1-month, 6-month, 12-month) accumulated precipitation relative to multi-year averages. A 93-year (1920–2012), high-resolution (250 m) gridded dataset of monthly rainfall available for the State of Hawai‘i was used to derive gridded, monthly SPI values for 1-, 3-, 6-, 9-, 12-, 24-, 36-, 48-, and 60-month intervals. Gridded SPI data were …

Global Warming, Benjamin H. Gray Mr.
English Department: Research for Change - Wicked Problems in Our World
Global warming is being affected in many ways on a daily basis and continuing using the same nonrenewable resources is hurting the human civilization as a whole today, and is going to hurt us even more in the future. The world is being affected economically today and is going to have to contribute a large sum of money to clean up the greenhouses gasses. There is also a problem with precipitation a drought due to the temperature and jet streams. Humans are choosing to migrate differently due to the change in temperatures and precipitation which goes hand in hand with …
Wildfires Force Thousands To Evacuate Near Los Angeles: Here’S How The 2020 Western Fire Season Got So Extreme, Mojtaba Sadegh, Ata Akbari Asanjan, Mohammad Reza Alizadeh
Wildfires Force Thousands To Evacuate Near Los Angeles: Here’S How The 2020 Western Fire Season Got So Extreme, Mojtaba Sadegh, Ata Akbari Asanjan, Mohammad Reza Alizadeh
Civil Engineering Faculty Publications and Presentations
Two wildfires erupted on the outskirts of cities near Los Angeles, forcing more than 100,000 people to evacuate their homes Monday as powerful Santa Ana winds swept the flames through dry grasses and brush. With strong winds and extremely low humidity, large parts of California were under red flag warnings.
High fire risk days have been common this year as the 2020 wildfire season shatters records across the West.
More than 4 million acres have burned in California – 4% of the state’s land area and more than double the previous annual record. Five of the state’s six largest historical …
Responding To Extremes: Managing Urban Water Scarcity In The Late Nineteenth-Century Straits Settlements, Fiona Williamson
Responding To Extremes: Managing Urban Water Scarcity In The Late Nineteenth-Century Straits Settlements, Fiona Williamson
Research Collection School of Social Sciences
In 1877, the major towns of the Straits Settlements - Singapore, George Town, Penang Island and Malacca - suffered a drought of exceptional magnitude. The drought’s natural instigator was the El Niño phase of the El Niño Southern Oscillation (ENSO), a climatic phenomenon then not understood by contemporary observers. The 1877 event has been explored in some depth for countries including India, China and Australia. Its impact on Southeast Asia however is less well-known and the story of how the event unfolded in Singapore and Malaysia has not been told. This paper explores how the contemporary British government responded to …

In summary, using available price risk management tools can effectively reduce some of the market price risk variability that is inherent in agricultural production that are caused by either production or price risk.
Utah County Level Drought Effect On Cattle Inventories 1981-2016, Fred Openshaw
Utah County Level Drought Effect On Cattle Inventories 1981-2016, Fred Openshaw
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Utah cattle industry generates 20.6% of sales value for the agricultural sector. As well, this industry encompasses about 34.4% of Utah farms. Besides these figures, Utah cattle ranchers depend heavily upon both public and private lands for grazing as a primary source of feed for their herds. The soil moisture levels of pasturelands impacts the forage yield for a particular year. As a result, the primary purpose of this research is to determine if drought impacts Utah county cattle inventory numbers and what the magnitude of the impact is by analyzing data from 1981 to 2016. A secondary purpose …
Impact Of Saturated Thickness To Protect Farmers From Drought In High Plains Aquifer, Olivier Tuyizere, Taro Mieno
Impact Of Saturated Thickness To Protect Farmers From Drought In High Plains Aquifer, Olivier Tuyizere, Taro Mieno
UCARE Research Products
●The High Plains aquifer is the primary source of water supply for irrigating major crops in the region including corn and soybeans ●Climate change is expected to reduce groundwater availability in High Plains Aquifer and increase extreme climatic events such as droughts. ●Aquifer depletion leads to lower well yields, which in turn diminish the effectiveness of irrigation against drought.
●Estimate the effect of saturated thickness to protect irrigated corn and soybeans production against severe drought in the High Plains Aquifer. ●Calculate the impact of aquifer depletion on farmers’ ability to protect against severe droughts based on the regression results.
Spatiotemporal Partitioning Of Mammalian Mesopredators In Response To Drought And Urbanization In California's Central Valley, Chad W. Moura
Spatiotemporal Partitioning Of Mammalian Mesopredators In Response To Drought And Urbanization In California's Central Valley, Chad W. Moura
Cal Poly Humboldt theses and projects
Mammalian mesopredators commonly associated with human dominated landscapes often exhibit generalist diets, behavioral plasticity, and relatively high reproductive rates. Because of this wide range of adaptive traits, ecologists have been speculative of what conditions may drive species to change their activity and behavior to avoid or mitigate against resource competition, intraguild predation, and human disturbance. I investigated a community of common mesopredators within the Sacramento Metropolitan Area of California’s Central Valley to address whether species are spatially and/or temporally partitioning due to a defacto apex predator, coyotes (Canis latrans), and humans alongside large landscape altering disturbances: urbanization and drought. I …
