Use and production of microalgae as food for nursery bivalves OMA
De Pauw, N..
The nutritional value of various foods and diets for juvenile bivalves is reviewed and commented. From all foods tested specific microalgues seem to be the most suited for young bivalves. Presently, serious alternatives for replacing living algae by inert, artificial feeds are practically inexistent, though research efforts are made in this direction. The various microalgae production-systems used for feeding juvenile bivalves are also reviewed. A literature survey and the COST inquiry held in 1979 by our laboratory revealed that nearly all commercial enterprises involved in nursery rearing of bivalve molluscs in Europe utilize natural phytoplankton as food. Culturing of the postlarvae is performed either <i>in situ</i> (in the sea) or in...

Possible Implications for U.S. Agriculture From Adoption of Select Dietary Guidelines AgEcon
Buzby, Jean C.; Wells, Hodan Farah; Vocke, Gary.
To help Americans meet nutritional requirements while staying within caloric recommendations, the 2005 Dietary Guidelines for Americans encourage consumption of fruits, vegetables, whole-grain products, and fat-free or low-fat milk or milk products. This report provides one view of the potential implications for U.S. agriculture if Americans changed their current consumption patterns to meet some of those guidelines. For Americans to meet the fruit, vegetable, and whole-grain recommendations, domestic crop acreage would need to increase by an estimated 7.4 million harvested acres, or 1.7 percent of total U.S. cropland in 2002. To meet the dairy guidelines, consumption of milk and milk products would have to increase by 66 percent; an increase of that...

Expert opinion and cuisine reputation in the market for restaurant meals AgEcon
Fogarty, James Joseph.
As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators, and other objective indicators in the market...

CHINA'S FOOD AND AGRICULTURE: ISSUES FOR THE 21ST CENTURY AgEcon
China's impact on world agricultural markets in coming decades will depend on many factors. Growing income and transition to modern urban lifestyles will increase demand for all foods, but demand will shift toward meat and high-value products. WTO accession may increase openness of China's agricultural trade and allow more imports. An understanding of geographic variations of consumption, production, trade, and policy is critical to understanding the vast China market. Development of transportation infrastructure and market channels will make it easier for food products to reach consumers. China's approach to biotechnology and its reform of institutions for allocating land, labor, and water inputs have important implications for agricultural productive...

The agri-food and other bio-based sectors in Spain. A description based on multiplier analysis AgEcon
Ferrari, Emanuele; Cardenete, Manuel Alejandro; Boulanger, Pierre; Delgado, M.C.; M'Barek, Robert.
The turnover of the EU agri-food sector overtops 2,000 billion Euros a year and employs roughly 22 millions workers. The focus of this paper is on the sectors directly linked to agricultural production and the food industry. Having a comprehensive understanding of extended agri-food economic linkages is critical when designing pertinent policies to deliver the full potential of strong EU agri-food and other bio-based sectors. A more disaggregated view is required. This study stars from a Social Accounting Matrices (SAM) for Spain with a highly disaggregated agricultural sector (AgroSAMs) for the year 2000. This study uses the AgroSAMs in its entire disaggregation, in order to provide a descriptive analysis of the agri-food and bio-based sectors. The limits...

Italian Consumer Acceptance of Nutritionally Enhanced GM Food AgEcon
Canavari, Maurizio; Tisselli, Farid; Nayga, Rodolfo M., Jr.; Scarpa, Riccardo.
The aim of this article is to evaluate Italian consumers’ acceptance and willingness to purchase GM foods based on the type of benefit (input vs output trait) and product (plant based vs animal based). Two surveys were administered in two consecutive years (2004 and 2005) and the data used to test for possible changes in consumer acceptance. The results of a multinomial logit analysis suggest that on average consumer acceptance for plant-based GM food was higher in 2005. This study confirmed the key role of information strategies to consumers, with the most relevant results being the role distorted information play in raising the consumer’s level of fear and perceived risk. Respondents also place a higher level of confidence on scientists who are generally...

Economic Returns to Public Agricultural Research AgEcon
Fuglie, Keith O.; Heisey, Paul W..
Over the last several decades, the U.S. agricultural sector has sustained impressive productivity growth. The Nation's agricultural research system, including Federal-State public research as well as private-sector research, has been a key driver of this growth. Economic analysis finds strong and consistent evidence that investment in agricultural research has yielded high returns per dollar spent. These returns include benefits not only to the farm sector but also to the food industry and consumers in the form of more abundant commodities at lower prices.

Risk Analysis in Selected European and International Food Chains AgEcon
Ameseder, Christoph; Haas, Rainer; Fritz, Melanie; Schiefer, Gerhard.
The purpose of this study is to assess and evaluate the most important risks in selected European and international food chains from the perspective of the buying company. The primary objective is to identify the “non-acceptable” risks in terms of damage potential and likelihood of occurrence of value chains in the sectors grain, meat, fruit and vegetable, and olive oil. Data was collected by each partner of the European research project “e-trust” (FP6-CT-2006-043056) by conducting 81 qualitative expert interviews with business leaders in Europe (Austria, Germany, Greece, Italy, Slovenia, Spain) as well as in Brazil, Turkey, and the USA. The study focuses on a wider supply chain or network perspective for the risk assessment. Methodically the assessed...

A Strategic Perspective on the Impact of Food Safety Standards on Developing Countries AgEcon
Henson, Spencer J.; Jaffee, Steven.
This paper explores the competing concepts of 'standards as barriers' and standards as catalysts' in the context of food safety standards in international trade in agricultural and food products. It is suggested that food safety standards can act as both a barrier to trade and the basis of competitive positioning for developing countries in international markets. This suggests that the application of a strategic framework to analyze and assess alternative responses to evolving food safety standards can throw some light on the circumstances under which standards act to prohibit trade or, alternatively, create competitive trade opportunities. The use of such a framework is illustrated through a brief case study of fish and fishery product exports from...

Sustainable food versus health concerns AgEcon
Avermaete, T.; Mathijs, Erik.
Simultaneous with the growing demand for sustainable food, statistics in all EU member states report consumption patterns that are characterized by too much fat, overdoses of sugar and a lack of fruits and vegetables. The streams of literature that investigate the factors influencing sustainable food consumption and healthy food consumption are largely separated. However, the question whether there is a positive relationship between consumer behaviour towards sustainable food and consumer behaviour towards healthy food remains largely unanswered. The purpose of this paper is to examine the relationship between the consumption of different types of sustainable food on the one hand, and healthy food patterns on the other. The study is based on a sample of...

Innovations at the Borderline of Food, Nutrition and Health in Germany - A Systems' Theory Approach AgEcon
Menrad, Klaus.
This article deals with the innovation system in Germany at the borderline of food, nutrition and health. After an overview over existing concepts to analyse innovations in system theory, the major factors (technologies, economic competence, institutional infrastructure, development block) are studied which determine the innovation system in this area in Germany. Afterwards recommendations are outlined on how to modify the innovation system in future.

ALBERTA AGRICULTURE AND FOOD TRADE: RECENT TRENDS AgEcon
Rosario, Joe A..
Exports have been an integral and essential feature of the agriculture and food industry in Alberta. This is a product of the province’s relatively low population and consumption base on the demand side juxtaposed with a large resource base of prime agriculture land for crop production and an abundance of range and pasture for grazing and forage for raising livestock on the supply side. A host of factors influence the disposition of surplus production or exports including global supply/demand balances, relative cost/price relations, structural changes through farm consolidation and scale economies, market access, exchange rates, sanitary and phyto‐sanitary standards and regulations, disease and pest related issues. The inherent nature of agriculture means...

FORECASTING FUTURE EMPLOYMENT OPPORTUNITIES FOR FOOD, AGRICULTURE, AND NATURAL RESOURCES HIGHER EDUCATION GRADUATES USING ADJUSTED BUREAU OF LABOR FORECASTS AgEcon
Bullock, K. Wayne; Litzenberg, Kerry K..
Forecasts of the number of future professionals required for an ongoing safe, efficient US food system are highly important. The demand for adequately prepared higher education graduates must be met by the US Food, Agriculture, and Natural Resources Education System. Without accurate forecasts of the human resource needs of the food sector of the economy, adequate professionals may not be available when needed. This research effort makes use of Bureau of Labor Statistics (BLS) forecasted employment opportunities. The estimation of professionals required in the food and agriculture sectors of the economy is developed by selecting and manipulating data from the BLS model that is relevant to food and agriculture careers. These forecasts of needed...

USING BEST WORST SCALING TO INVESTIGATE PERCEPTIONS OF CONTROL AND CONCERN OVER FOOD AND NON-FOOD RISKS AgEcon
Erdem, Seda; Rigby, Dan.
This research locates a series of risks or hazards within a framework characterized by the level of control respondents believe they have over the risks, and the level of worry the risks prompt. It does this for a set of both food and non-food risks. The means by which this is done is novel and differs from past risk perception analyses in that it asks people directly regarding their relative assessments of the levels of control and worry regarding the risks presented. The cognitive burden associated with people ranking and scaling items in large sets is notoriously heavy and so this study uses an elicitation method designed to make the process intuitive and cognitively manageable for respondents. The substantive analysis of the risk perceptions has 4 main...

Is there an Intrahousehold Flypaper Effect? : Evidence from a School Feeding Program AgEcon
Jacoby, Hanan G..
Are public transfers targeted toward children largely neutralized by the household, as the theory of altruism implies, or is there an intrahousehold “flypaper effect” whereby such transfers “stick” to the child? This paper studies the impact of a school feeding program on child caloric intake in the Philippines. Because children are interviewed on school days and nonschool days, and because some schools offer a feeding program and others do not, the dietary impact of the program is identified under mild restrictions. The empirical results confirm an intrahousehold flypaper effect; indeed, they indicate virtually no intrahousehold reallocation of calories in response to the feeding program. In poorer households, however, children’s gains from the program...
