Última AGRICULTURAL BIOTECHNOLOGY: FARM-LEVEL, MARKET, AND POLICY CONSIDERATIONS AgEcon Van der Sluis, Evert; Diersen, Matthew A.; Dobbs, Thomas L.. This study provides an overview of the economic costs, benefits, and risks involved with agricultural biotechnology at the farm level, at the market level, and for the farm and food system as a whole. Both advantages and disadvantages of agricultural biotechnology are discussed. Among the drivers of U.S. domestic and international consumer demand for transgenic crop products discussed are environmental and food safety concerns. A comparison is made between a "science-based" regulatory framework and a policy based on the precautionary principle. The authors argue that open dialogue is needed for achieving improved public understanding of agricultural biotechnology, and that analyses need to go beyond discussing the scientific merits of biotechnology, to...

Ano: 2002 URL: http://purl.umn.edu/14654 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 natural conservation of coastal lagoons is important not only for their ecological importance, but also because of the valuable ecosystem services they provide for human welfare and wellbeing. Coastal lagoons are shallow semi-enclosed systems that support important habitats such as wetlands, mangroves, salt-marshes and seagrass meadows, as well as a rich biodiversity. Coastal lagoons are also complex social-ecological systems and the ecosystem services that lagoons deliver provide livelihoods, benefits wellbeing and welfare to humans. This study assessed, quantified and valued the ecosystem services of 32 coastal lagoons. The main findings of the study were: (i) the definitions of ecosystem services are still not generally accepted; (ii) the...

Concerns about the impact of farm production on the quality of the Nation's drinking and recreational water resources have risen over the past 10 years. Because point sources of pollution were controlled first, agricultural nonpoint sources have become the Nation's largest remaining single water-quality problem. Both public and private costs of policies that address the conflict between agricultural production and water quality are relevant, but measuring the off-farm benefits and costs of changing water quality is difficult. Many of the values placed on these resources are not measured in traditional ways through market prices. This report explores the use of nonmarket valuation methods to estimate the benefits of protecting or improving rural water...

Ano: 1995 URL: http://purl.umn.edu/33949 Benefits of Reducing Nutrient Variation in Fertilizer Mixes AgEcon Chamberlain, Peter J.; Shumway, C. Richard. This article examines nutrient deficiencies (below guaranteed levels) in major blended commercial fertilizers and their economic impact on net revenues of Texas farmers. Violations by fertilizer manufactures in meeting specific labeled nutrient levels were more than offset in economic value by excesses in other nutrients and by production of blends that contained more than the required levels of all nutrients. The study concluded that economic losses to Texas farmers would likely be associated with requiring nutrient levels to be more tightly distributed around the guaranteed or labeled nutrient levels.

Ano: 1994 URL: http://purl.umn.edu/62353 Benefits of Safer Drinking Water: The Value of Nitrate Reduction AgEcon Crutchfield, Stephen R.; Cooper, Joseph C.; Hellerstein, Daniel. Nitrates in drinking water, which may come from nitrogen fertilizers applied to crops, are a potential health risk. This report evaluates the potential benefits of reducing human exposure to nitrates in the drinking water supply. In a survey, respondents were asked a series of questions about their willingness to pay for a hypothetical water filter, which would reduce their risk of nitrate exposure. If nitrates in the respondent's drinking water were to exceed the EPA minimum safety standard, they would be willing to pay $45 to $60, per household, per month, to reduce nitrates in their drinking water to the minimum safety standard. There are 2.9 million households in the four regions studied (White River area of Indiana, Central Nebraska, Lower...

Ano: 1997 URL: http://purl.umn.edu/34025 Biotechnology's Potential Contribution to Global Wood Supply and Forest Conservation AgEcon Sedjo, Roger A.. Over the past 30 years, industrial plantation forests have become a major supplier of industrial wood. There are several reasons for this, including the improved economics of planted forests due to biotechnological innovations, the increases in natural forest wood costs due to increasing inaccessibility, and rising wood costs from natural forests due to new environmental restrictions related to logging. Forestry today is on the threshold of the widespread introduction of biotechnology into its operational practices. In many cases, the biotechnology likely to be introduced is simply an extension of that being utilized in agriculture, such as herbicide-tolerant genes. However, biotechnology in forestry also is developing applications unique to forestry,...

Ano: 2001 URL: http://purl.umn.edu/10708 Breeding and quality analysis of rapeseed AgEcon Chudleigh, Peter D.. This study is an ex-post, economic assessment of two projects supported by ACIAR and concerned with the breeding and quality analysis of rapeseed in Australia and China. These projects were carried out sequentially with the first one commencing on 1 July 1986. The second one was completed on 30 June 1991. The projects were essentially an exchange of knowledge and germplasm of rape (Brassica napus) between plant breeders in Australia and China. The projects resulted in the release of varieties of rape that yielded improved seed in Australia, China and other developed and developing countries. An economic evaluation of these projects was made in 1991 and the results published in Chudleigh (1991). Assumptions made in the 1991 analysis have now been updated....

Human-wildlife conflicts are a global problem, and are occurring in many countries where human and wildlife requirements overlap. Conflicts are particularly common near protected areas where societal unrest is large. To ease conflict, integrated conservation and development projects (ICDPs) have been implemented. The Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) is an example of an ICDP. We hypothesized that (i) a higher perceived effectiveness of CAMPFIRE would be associated with a decline in human-wildlife conflicts, and (ii) local communities with higher perceived effectiveness of CAMPFIRE programs would have more favorable attitudes towards problematic wild animals.

Ano: 2013 Chronic hepatitis C and fibrosis: evidences for possible estrogen benefits BJID Codes,Liana; Matos,Ludmilla; Paraná,Raymundo. 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.

The present study attempts to offer more insights into the Greek wine market with emphasis on wines produced from organically grown grapes by relating wine choice to consumers' personal value structure. With the use of a qualitative sample and applying the Means-end Chains methodology and the corresponding "laddering" interviewing technique, it attempts first to reveal the way basic motives are linked to wine shopping behaviour of consumers and the way wine purchase-relevant knowledge is stored and organised in their memory in relation to their personal values. Then, by discriminating between organic food buyers and non-buyers, the study identifies motivational and cognitive discriminating differences between the two consumer types, which can offer a solid...

Ano: 2006 URL: http://purl.umn.edu/10059 Economic Analysis of the Liberalization of Red Meat Markets in the Pacific Region from 1988 to 2007 AgEcon Charlebois, Pierre; Gagne, Stephan; Gendron, Carole. The liberalization of red meat (beef and pork) markets since 1988 is a good example of government action that has led to significant gains for the Canadian and American agri-food industries. Japan, South Korea and Mexico are the main countries that have liberalized their red meat markets since 1988. This industry has also benefited from the agreement between Canada and the United States. It has also made gain from the liberalization of the pork market in Australia and the Philippines, and the beef market in Indonesia. This analysis captures the impact on the price received by farmers as well as on Canadian production in the absence of these increased market access. The combination of lower prices and lower production would have caused annual average...

Ano: 2008 URL: http://purl.umn.edu/47133 Estimating Water Quality Benefits: Theoretical and Methodological Issues AgEcon Ribaudo, Marc; Hellerstein, Daniel. Knowledge of the benefits and costs to water users is required for a complete assessment of policies to create incentives for water quality improving changes in agricultural production. A number of benefit estimation methods are required to handle the varying nature of water quality effects. This report reviews practical approaches and theoretical foundations for estimating the economic value of changes in water quality to recreation, navigation, reservoirs, municipal water treatment and use, and roadside drainage ditches.

Ano: 1992 URL: http://purl.umn.edu/33586 Family Size, Economics and Child Gender Preference: A Case Study in the Nyeri District of Kenya AgEcon Kiriti, Tabitha; Tisdell, Clement A.. Kenyan women have more children, especially in rural areas, than in most developing nations. This is widely believed to be an impediment to Kenya’s economic development. Thus, factors influencing family size in the Kenyan context are important for its future. A brief review of economic theories of fertility leads to the conclusion that both economics and social/cultural factors must be considered simultaneously when examining factors that determine the number of children in a family. The need to do this is borne out in Kenya’s situation by utilising responses from a random sample of rural households in the Nyeri district of Kenya. Economic and social/cultural factors intertwine to influence family sizes in this district. After providing a summary of the...

Ano: 2014 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: 1989 URL: http://purl.umn.edu/114039 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.
