Última Valuing the Roundup Ready® Soybean Weed Management Program AgEcon Aultman, Stephen; Hurley, Terrance M.; Mitchell, Paul D.; Frisvold, George B.. This study examines soybean grower adoption of the Roundup Ready® (RR) weed management program with and without a residual herbicide application, and grower concerns regarding weed resistance to herbicides using telephone survey data from of 357 growers in 2007. It also estimates the pecuniary and non-pecuniary benefits enjoyed by growers from their RR program. The results indicate that soybean growers planned to treat 29 percent of their RR acres with a residual herbicide in 2008. More than half (53%) of the growers survey were concerned about weed resistance. The estimated expected benefit of the RR program in 2008 was $10.17 per acre, which translates into about $727 million with 75.7 million acres of soybean in the U.S. in 2008. The estimated...

Ano: 2009 URL: http://purl.umn.edu/49342 Increasing agricultural production in Nepal: role of low-cost irrigation development through farmer participation AgEcon Pradhan, Prachanda. This book reveals that Nepal irrigation policy directives and resources must be channeled to encourage the participation of beneficiaries and to focus the functions of the Department of Irrigation on a management perspective . The low cost approaches recommended in the paper include : 1) incorporating farmer participation in operation and management, 2) considering lower cost structures in surface irrigation and underground water development and, 3) improving the management of irrigation systems Tipo: Book Palavras-chave: Agricultural production; Farmer participation; Irrigated farming; Benefits; Cost recovery; Farmer-agency interactions; Farmer managed irrigation systems; Farm Management. Ano: 1989 URL: http://purl.umn.edu/114039 Perceived Traceability Costs and Benefits in the Italian Fisheries Supply Chain AgEcon Asioli, Daniele; Boecker, Andreas; Canavari, Maurizio. The paper proposes a model in which it is hypothesized that firm characteristics influence both costs and benefits of traceability. The proposed model differentiates between aggregate measures and specific categories, as well as between expected costs and benefits on the one hand and perceived actual outcomes on the other, and is tested in a series of regression analyses based on a survey sample of 60 Italian fish processors. The findings indicate that firm characteristics are not strongly associated with any specific cost or benefit measure. However, expected overall benefits are highly significantly impacted by firm size and the number of quality management systems certified, while actual overall benefits only by firm size. Finally, the study also finds...

Ano: 1995 URL: http://purl.umn.edu/113705 Improved drying of high moisture grains AgEcon McLeod, Ross. An economic evaluation of three ACIAR projects whose primary objective was to improve postharvest grain drying in Thailand and Australia is provided in this report. During 1983–1996, ACIAR invested A$1.2 million in research designed to improve grain drying in these countries. Based on current adoption, the investment has resulted in a realised net present value of A$3.6 million. A benefit–cost ratio of 3:1 was estimated for the projects. In other words, for each dollar invested, three dollars of project benefits have resulted. A high proportion of realised benefits was estimated to accrue to Australian rice producers, through reduced grain drying costs, while benefits have also been captured by the Thai rice production industry through reduced postharvest...

Ano: 1999 URL: http://purl.umn.edu/47692 INFORMATION POLICY AND GENETICALLY MODIFIED FOOD: WEIGHING THE BENEFITS AND COSTS AgEcon Teisl, Mario F.; Caswell, Julie A.. The labeling of genetically modified foods (GMFs) is the topic of a debate that could dramatically alter the structure of the U.S. and international food industry. The current lack of harmonization of policy across countries makes GMF labeling an international trade issue. The U.S. and Canada do not require GMFs to be labeled unless the GMF is significantly different than the conventional food or the GMF presents a health concern. However, many other countries are requiring GMFs to be labeled. This paper discusses empirical work on the sources and magnitude of benefits and costs from labeling programs, with particular emphasis on the impact of the design of the labeling program on benefits and costs.

Ano: 2003 URL: http://purl.umn.edu/14534 An alternative for antibiotic se in poultry: probiotics Rev. Bras. Ciênc. Avic. Edens,FW. Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic usage in livestock and poultry. Therefore, alternatives to the use of growth promoting antibiotics must be found to promote growth or production at or near the genetic potential of the modern day broiler, turkey, and egg producer. The use of probiotics has many potential benefits and include modified host metabolism, immuno-stimulation, anti-inflammatory reactions, exclusion and killing of pathogens in...

The main injury caused by hepatitis C virus is the hepatic fibrosis, as a result of a chronic inflammatory process in the liver characterized by the deposit of components from the extracellular matrix. The fibrosis development leads to the modification of the hepatic architecture, of the hepatocellular function and to irregularities in the microcirculation. The tissue remodeling process observed in fibrosis has stellate cells, located at the space of Disse, as main acting agents. These cells, in response to a harmful stimulus, undergo phenotypic changes from non-proliferating cells to proliferating cells that express a- smooth-muscle actin (a-SMA), a process called as transdifferentiation. There are evidences that the oxidative stress is involved in the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hepatitis C; Fibrosis; Estrogen; Benefits.
