A Comparison Of Costs And Returns For Organic And Conventional Cabernet Sauvignon Grape Production In San Luis Obispo County, Amanda N. Johansen Jun 2010

A Comparison Of Costs And Returns For Organic And Conventional Cabernet Sauvignon Grape Production In San Luis Obispo County, Amanda N. Johansen

Agribusiness

This study examined the differences in costs and profitability for established conventional and organic Cabernet Sauvignon vineyards in the Edna Valley region of San Luis Obispo County, California. The study used a partial budgeting approach to compare cost and profitability for established vineyards for 2009, and thus ignored transition costs. Data were obtained from UC Davis cost studies for organic and conventional grape production in other regions of California in previous years. Adjustments made to these costs to account for changes in input use, input costs and grape prices in San Luis Obispo County during the 2009 growing season.

Evaluating Native Wheatgrasses For Restoration Of Sagebrush Steppes, Jayanti Ray Mukherjee May 2010

Evaluating Native Wheatgrasses For Restoration Of Sagebrush Steppes, Jayanti Ray Mukherjee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pseudoroegneria spicata and Elymus wawawaiensis are two native perennial bunchgrasses of North America's Intermountain West. Frequent drought, past overgrazing practices, subsequent weed invasions, and increased wildfire frequency have combined to severely degrade natural landscapes in the region, leading to a decline in the abundance of native vegetation. Being formerly widespread throughout the region, P. spicata is a favorite for restoration purposes in the Intermountain West. Elymus wawawaiensis, which occupies a more restricted distribution in the Intermountain West, is often used as a restoration surrogate for P. spicata. However, since most restoration sites are outside the native range of …

Temperature Influence And Heat Management Requirements Of Microalgae Cultivation In Photobioreactors, Thomas Hagen Mehlitz Feb 2009

Temperature Influence And Heat Management Requirements Of Microalgae Cultivation In Photobioreactors, Thomas Hagen Mehlitz

Master's Theses

Microalgae are considered one of the most promising feedstocks for biofuel production for the future. The most efficient way to produce vast amounts of algal biomass is the use of closed tubular photobioreactors (PBR). The heat requirement for a given system is a major concern since the best algae growth rates are obtained between 25-30 °C, depending on the specific strain. A procedure to determine temperature influence on algal growth rates was developed for a lab-scale PBR system using the species Chlorella. A maximum growth rate of 1.44 doublings per day at 29 °C (optimal temperature) was determined. In addition, …

Grain sorghum (Sorghum bicolor (L.) Moench) is a major crop in many parts of Africa and is noted for its versatility and diversity. It is adapted over a wide range of precipitation and temperature levels and is produced at sea level to above 2000 m altitude. In eastern and southern Africa, it is primarily a crop of resource-poor, small-scale farmers and is typically produced under adverse conditions such as low input use and marginal lands. There are numerous biotic and abiotic constraints to production. The grain and stover are used in many different ways with localized preferences. Much information …

The Potential Role Of Probiotics In Reducing Poverty-Associated Infections In Developing Countries, Kingsley Anukam Oct 2007

The Potential Role Of Probiotics In Reducing Poverty-Associated Infections In Developing Countries, Kingsley Anukam

Data and Test Instruments

Probiotics are defined by the Food and Agricultural Organization/ World Health Organization as “live microorganisms which when administered in adequate amounts confer a health benefit on the host” [1]. The potential benefits of their use have not been adequately investigated, especially in the developing world. Japan introduced Yakult, a probiotic fermented food drink in 1935, and in the Northern hemisphere, research and use of probiotics has gained an unprecedented momentum in the last decade [2]. Use of probiotics is not uncommon in Europe [3], but in many developing countries use of probiotics in its present definition is a foreign concept. …

Conclusions

Based on the practical community applications of woody buffe rs and multifuncti onal areas that grew from the ini tial concepts ofecobelts. we are convinced that this type of initiative is a viable option in establishing a positive interface between different types of human activities. The challenge becomes more real every day, as cities expand and both city-edge subdivisions and acreages create ever more interfaces between people with different and often con!1icting activities and basic values. There is a need to provide some logical and acceptable boundary between these people and their different lifestyles. It is also desirable to …

Comparison Of 'Organic' And 'Conventional' Grains And Soybean Prices In The Northern Great Plains And Upper Midwest: 1995 Through 2003, Nicholas Streff, Thomas L. Dobbs

Economics Pamphlet Series (1985-2016)

Price premiums for organic crops drew the attention of an increasing number of farmers throughout the 1990s. Premiums contributed to the expansion of U.S. farmland managed under organic farming systems during that time period. Expansion of organic farming systems continued at least through 2001. According to the U.S. Department of Agriculture (USDA) Economic Research Service's most recent data on organic farming systems, U.S. farmers and ranchers added almost one million acres of certified organic farmland between 1997 and 2001, an increase of 74 percent. Over that same time frame, certified organic cropland increased by 53 percent). The USDA implemented national …

Sustainable Agricultural Growth In The Al-Ahsa Oasis Of Saudi Arabia: Harmonizing Wto Goals, Environmental Constraints, And National Food Security Issues, Ahmad Mohammad Al-Mass

All-Inclusive List of Electronic Theses and Dissertations

Local agricultural practices in Saudi Arabia today are shaped by local land, labor, and technological conditions, by national governmental regulations, subsidies, and price controls, and by the global impacts of foreign competition and goals of international organizations such as the World Trade Organization (WTO). Human and natural forces over which local oasis residents have no control exert more influence upon their social and economic life than do daily agricultural tasks. These forces are recognized by Saudi national planners, for agricultural development is very important to the government and to oasis dwellers in Saudi Arabia. Reducing the loss of foreign exchange, …


Agricultural Biotechnology In China: An Unreachable Goal?, Stanley P. Kowalski Jan 2003

Agricultural Biotechnology In China: An Unreachable Goal?, Stanley P. Kowalski

Law Faculty Scholarship

Recently there has been much discussion about the People’s Republic of China’s (PR) investment in and commitment to agricultural biotechnology (agri-biotech). Rapid economic expansion, population growth and technological development are changing the PRC; accompanying these changes is increased demand for high-quality food and fibre. Agri-biotech is optimistically viewed as an important way to meet these demands. Whereas Chinese technological capacity in agri-biotech has advanced significantly over the past decade, it may be unable to meet these challenges. Even when this capacity is combined with good intentions, enlightened policy and large capital outlays, accelerated development of agri-biotech may nevertheless be precluded. …


Golden Rice: A Case Study In Intellectual Property Management And International Capacity Building, Stanley P. Kowalski, R. David Kryder Mar 2002

Golden Rice: A Case Study In Intellectual Property Management And International Capacity Building, Stanley P. Kowalski, R. David Kryder

Law Faculty Scholarship

In order for agricultural biotechnology (agri-biotech) to play a larger role in the development of sustainable agricultural systems, intellectual property (IP) rights management must be addressed. These issues are not limited to developing countries. With increased globalization, the management of agri-biotech IP rights affects both developing and industrialized countries. In industrialized countries, for example, IP rights risk management entails protection of inventions via strong patent portfolios. For developing countries, IP rights risk management includes the acquisition of rights requisite for the use of inventions essential to the basic welfare of the population. Strategies are needed to bridge these disparate IP …
