2018 - Groundwater Management In California, Michael Hanemann Dec 2018

2018 - Groundwater Management In California, Michael Hanemann

Related Research and Documents

In 2014, the California legislature for the first time took some steps to create a framework for regulating groundwater pumping in over-drafted basins by adopting the Sustainable Groundwater Management Act (SGMA), representing California's first statewide groundwater management planning program. SGMA called for local agencies to develop groundwater sustainability plans within the next five to seven years and then achieve sustainable levels of groundwater extraction by approximately 2040 to 2045. California's prior efforts to regulate groundwater extraction is discussed, as well as groundwater depletion.

1998 - Salinas Valley Water (Preliminary Analysis Of) The Cause And Cost Of Seawater Intrusion

Miscellaneous Monterey and San Luis Obispo County Documents and Reports

An analysis of the historical cause of seawater intrusion in the Pressure Area of Monterey County. An annual overdraft of groundwater resources near the coast coupled with a seasonal cycle of over pumping created a reversal in the groundwater gradient and associated cones of depression. "Marine intrusion has occurred in the 180-foot aquifer in recent years as a result of overdrafts." (Bulletin 52, 1946, p.27). The only overdrafts on groundwater in the Salinas Valley were in the East Side and Pressure Areas. "There was no shortage of groundwater in the remainder of the basin and no threat of deficiency under …

Biological Sciences Faculty Research

Environmental stress is a major driver of ecological community dynamics and agricultural productivity. This is especially true for soil water availability, because drought is the greatest abiotic inhibitor of worldwide crop yields. Here, we test the genetic basis of drought responses in the genetic model for C4 perennial grasses, Panicum hallii, through population genomics, field-scale gene-expression (eQTL) analysis, and comparison of two complete genomes. While gene expression networks are dominated by local cis-regulatory elements, we observe three genomic hotspots of unlinked trans-regulatory loci. These regulatory hubs are four times more drought responsive than the genome-wide average. Additionally, cis- and trans-regulatory …

Maxwell H. Gluck Equine Research Center Faculty Publications

Recent advances in genomic sequencing technology and computational assembly methods have allowed scientists to improve reference genome assemblies in terms of contiguity and composition. EquCab2, a reference genome for the domestic horse, was released in 2007. Although of equal or better quality compared to other first-generation Sanger assemblies, it had many of the shortcomings common to them. In 2014, the equine genomics research community began a project to improve the reference sequence for the horse, building upon the solid foundation of EquCab2 and incorporating new short-read data, long-read data, and proximity ligation data. Here, we present EquCab3. The count of …

Manure Application Timing Drives Energy Absorption For Snowmelt On An Agricultural Soil, Melanie N. Stock, Francisco J. Arriaga, Peter A. Vadas, Krishnapuram G. Karthikeyan

Plants, Soils, and Climate Faculty Publications

Reducing agricultural runoff year-round is important, in particular during snowmelt events on landscapes that receive wintertime applications of manure. To help inform manure guidelines, process-level data are needed that link management scenarios with the complexity of snowmelt, hence runoff. Albedo and radiative energy fluxes are strong drivers of thaw, but applying these mechanistic measurements across multiple, plot-scale management treatments over time presents a logistical challenge. The objective of this study was to first develop a practical field approach to estimate winter albedo in plot-scale field research with multiple management scenarios. The second objective was to quantify the radiative drivers of …

Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs Oct 2018

Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs

Honors Theses

This appraisal attempts to remove subjectivity from the appraisal process and replace it with quantitative analysis of known data to generate a fair market value of the subject property. Two methods of appraisal were used, the income approach and the comparable sales approach. For the income approach, I used the average cash rent for the region, the current property taxes for the subject property, and a capitalization rate based on Stokes' (2018) capitalization rate formula to arrive at my income-based valuation. For the comparable sales approach, I utilized Stokes' (2018) research in optimization modeling to estimate a market value for …

Rnai Targeting Of Manduca Sexta Using Chloroplast-Encoded Long Dsrna, William Burke

Electronic Thesis and Dissertation Repository

Pest management strategies are crucial for reducing insect crop damage, and methods with species-specific effect are particularly desirable. Expressing dsRNA with sequence complementarity to a vital gene of feeding pests is a strategy that has shown potential. I modified the chloroplast genome of cultivated tobacco, Nicotiana tabacum, by adding a sequence encoding a 2222 base pair dsRNA complementary to the vacuolar-type H+-ATPase subunit A mRNA of Manduca sexta and demonstrated expression of the product in leaves of the plants. Although feeding this same dsRNA that was synthesized in vitro to larvae knocked down expression of the target …

Wild, Native Bees And Managed Honey Bees Benefit From Similar Agricultural Land Uses, Elaine Evans, Matthew Smart, Dan Cariveau, Marla Spivak

Department of Entomology: Faculty Publications

Although both managed and unmanaged bees are important pollinators of crops and wild plants, efforts to address questions about landscapes that best support pollinators often focus on either wild pollinators or honey bees. This study examined if there was concordance between the success of wild bee communities and managed honey bee colonies at sites varying in floral availability and disturbance level in a predominantly agricultural landscape. We also determined which agricultural land uses best supported wild bee communities. The study area in the state of North Dakota in Northern Great Plains in North America is home to understudied native bee …
