Provedor de dados: 14
Autores: PEDROZA FILHO, M. X.; RIBEIRO, V. S.; ROCHA, H. S.; UMMUS, M. E.; VALE, T. M. do.
A produção de tilápia tem crescido de forma constante nos últimos anos, assegurando a posição de espécie mais produzida na piscicultura brasileira. Apesar de ser produzida em quase todo o Brasil, a cadeia produtiva da tilápia apresenta uma concentração em determinadas microrregiões, sendo que os polos mais importantes em termos de volume de produção estão localizados nas regiões Sul, Sudeste e Nordeste. O presente estudo tem por objetivo fazer uma análise da cadeia produtiva da tilápia nos principais polos de produção do Brasil, a partir de entrevistas feita a produtores e demais agentes do setor. Os resultados indicam que os polos de tilapicultura são muitos diferentes quanto às suas características produtivas, socioeconômicas e estruturais. De uma...

Understanding patterns and processes in models of trophic cascades
Provedor de dados: 5
Autores: Heath, Michael R.; Speirs, Douglas C.; Steele, John H.
Climate fluctuations and human exploitation are causing global changes in nutrient enrichment of terrestrial and aquatic ecosystems and declining abundances of apex predators. The resulting trophic cascades have had profound effects on food webs, leading to significant economic and societal consequences. However, the strength of cascades-that is the extent to which a disturbance is diminished as it propagates through a food web-varies widely between ecosystems, and there is no formal theory as to why this should be so. Some food chain models reproduce cascade effects seen in nature, but to what extent is this dependent on their formulation? We show that inclusion of processes represented mathematically as density-dependent regulation of either consumer...

Firms' strategies and voluntary traceability: an empirical analysis in Italian food chains
Provedor de dados: 31
Autores: Stranieri,   Stefanella; Banterle,   Alessandro.
In international food markets, voluntary traceability systems have increased their role in guaranteeing high safety and quality standards for the consumer. Such systems are also among the strategies firms employ to differentiate products and strengthen competitive advantage in both the national and international market. Voluntary traceability has significant implications on the organisation of economic relationships within food supply chains. This paper focuses on this aspect and analyses the effects of voluntary traceability on vertical co- ordination using a transaction cost perspective. The analysis makes reference to the Italian situation where the national standard organisation has introduced standard rules for voluntary traceability (UNI 10939; ISO...

Fish Chain Performance in Madrid Market: An Empirical Analysis
Provedor de dados: 31
Autores: de Felipe,   Isabel; Briz,   Julian.
Food chain analysis is becoming a useful instrument to increase efficiency. We focus the attention in the fish sector looking at the links from consumer to wholesalers in the region of Madrid. In order to get adequate information we developed face to face enquiries to the consumers, retailers and wholesalers. The analysis of the Madrid market give us a useful approach of the national and international sector, due to the fact that Mercamadrid is the biggest fish wholesale market in Europe, and the consumption in Madrid is representative in many ways of the Spanish market. Finally there are some conclusions and recommendations oriented toward the stakeholders.

Product Quality in the Food Chain: Do Cooperatives Offer High Quality Products?
Provedor de dados: 31
Autores: Pennerstorfer,   Dieter; Weiss,   Christoph R.
Cooperatives and investor-owned firms are alternative forms of business organisation that coexist and compete in many markets. The theoretical literature has identified a number of comparative advantages and disadvantages of cooperatives. Decentralized decision making within cooperatives may lead to quality coordination problems (free-riding on product quality), for example: whereas the individual member has to bear the full costs associated with higher quality, the benefits of delivering higher quality will be shared among all members. The present paper investigates this free-riding problem in determining product quality within a marketing cooperative in a vertically related market (food chain). On the basis of a mixed-oligopoly model, we show that the...

How changes in consumer behaviour and retailing affect competence requirements for food producers and processors
Provedor de dados: 31
Autores: Grunert,   Klaus G.
This paper analyses the changing competence requirements which members of the food chain face in their pursuit of competitive advantage. Two groups of trends serve as point of departure: more dynamic and heterogeneous consumer demands, which can be analysed in terms of consumer demands for sensory, health, process and convenience qualities, and changing roles for retailers in the food chain. Based on these trends, it is argued that competencies which can increase producers‘ level of market orientation get increased weight in the attainment of competitive advantage, and three types of competencies are singled out as especially important: consumer understanding, relationship management, and new product development. The development of market-related...

Value Sharing and Food System Dynamics for Milk, Tomato, and Cereals Food Chains
Provedor de dados: 31
Autores: Bertazzoli,   Aldo; Ghelfi,   Rino; Rivaroli,   Sergio; Samoggia,   Antonella.
The aim of the paper is to analyse value sharing and food system dynamics of milk, tomato, and cereals food chains, so to explore the agro‐food enterprises capacity to be competitive and sustainable. The paper is based on the functionalist approach of Malassis and the notion of the system of the General Systems Theory. The methodology is aimed at creating a consolidated financial statement for each food chain so to re‐create the chain value and identify how this is shared among the different food chain stages. The analysis is carried out on primary and secondary data: around 2400 financial statements concerning 480 enterprises from 2003 to 2007 and stakeholders’ interviews. Results show that value is usually created in the processing and distribution...

A COMPARATIVE ANALYSIS OF FOOD QUALITY ASSURANCE SCHEMES: THE CASE OF NEULAND AND EUREPGAP
Provedor de dados: 31
Autores: Gay,   Stephan Hubertus; Schneider,   Andreas.
Food Quality Assurance Schemes (QAS) are widely applied in the European Union. Neuland and EurepGAP represent two different approaches. Neuland differentiates meat clearly by a strict emphasis on rules regarding animal welfare to provide consumers with meat produced at a high animal welfare standard. EurepGAP certifies the compliance to international accepted standards with regard to Good Agricultural Practise to ease the exchange of products throughout the supply chain. In terms of overall benefits and costs, the study showed that for both QAS the benefits clearly outweigh the costs. This paper compares the schemes and their implications for the agro-food chain.

Food Chain Concept in Food and Rural Policy
Provedor de dados: 31
Autores: Bertazzoli,   Aldo; Ghelfi,   Rino; Rivaroli,   Sergio; Samoggia,   Antonella.
Food chain concept was firstly used as a private sector concept applied in order to optimise chain organisation and to create value along the chain. It is now becoming an approach to understand relations within a socio-economic area, both for economic and production aims and to gain a territorial and rural development perspective. Currently food chain policy is often the result of a negotiating process involving different socio-economic policy areas and many stakeholders. The objective of the present paper is to analyse the food chain concept in rural and food policy context, to explore its interconnections with other socio-economic policy areas, and to identify the main policy perspectives in which the concept of food chain was used. A significant number...

Autores: Bertazzoli,   Aldo; Fiorini,   A.; Ghelfi,   Rino; Rivaroli,   Sergio; Samoggia,   Antonella; Mazzotti,   V.
The aim of the paper is to analyse patterns of value system sharing along food chains, so to explore the agro-food enterprises capacity to be competitive and sustainable. The research focused on three food chains: potato, fruit, and Grana cheese of Emilia Romagna region. The paper adopts the value system approach. The methodology is aimed at creating a consolidated financial statement for each food chain so to re-create the chain operating profit and identify how this is shared among the different food chain stages. The analysis is carried out on 189 enterprises for the potato chain, 187 for the fruit chain and 203 for the cheese chain. The number of enterprises was invariable over the 5 year 2003-2007, leading to some 2,900 financial statement analysis....

The current situation of EU’s food chain
Provedor de dados: 31
Autores: Bartha,   Andrea; Balogh,   Viktoria; Nabradi,   Andras.
The sharp fluctuations in agricultural commodity and food prices at a time of great uncertainty about the economic outlook illustrate the need to improve the functioning of the European food supply chain with a view to enhancing its efficiency and competitiveness. Better regulation and ensuring a vigorous and coherent enforcement of competition and consumer protection rules will contribute to limiting price increases for the benefit of European consumers, in particular lower income households. Moreover, it will also help overcome the present fragmentation of the food supply chain and remove artificial entry barriers for producers, which will help European consumers benefit from the widest possible choice of quality food products. Additionally, this could...

What Can We Learn from Best Practices Regarding Food Chain Transparency?
Provedor de dados: 31
Autores: Molnar,   Adrienn; Van Lembergen,   Katrien; Gellynck,   Xavier; Sebok,   Andras; Berczeli,   Attila.
This paper reports on food chain transparency. The research specifically aims to investigate best practices. Therefore, inductive research was conducted, starting with the identification of best practices. Further, underlying patterns were investigated to derive hypotheses and to develop a theoretical framework. These were confronted with literature findings which resulted in the validation of the hypotheses and the theoretical framework. Overall it can be concluded that several types of food chain transparency exist, whereas the different types represent a hierarchy of transparency domains, and that the basis mainly applies to information quality. In addition, it is shown that performance indicators measure directly or indirectly the success of...

Vertical price formation in the Finnish food chain
Provedor de dados: 31
Autores: Karikallio,   Hanna; Arovuori,   Kyösti; Pyykkonen,   Perttu.
In this paper we analyse, how food prices have been spread between different actors in the Finnish food chain in 2000-2007. In addition, we compare price formation in Finland to eight other countries. We argue that the main factors explaining different food price behaviour between different countries especially in Europe are; the level of processing in the consumed food products, domestic competition, availability of substitute products, domestic consumption structure and consumers’ preferences. Our results show, that retailers’ share of food prices has increased in Finland, while both the farmers’ and processors’ share has been decreasing. This development differs significantly between countries. Yet, it seems that the lack of competition gives retail...

Data Availability for Carbon Calculators in Measuring GHG Emissions Produced by the Food Sector
Provedor de dados: 31
Autores: Amani,   Pegah; Schiefer,   Gerhard.
The continuing increase in burning fossil fuels over recent decades along with the changing land use have resulted in a considerable increase in the amount of greenhouse gases (GHGs) which can potentially lead to climate change. Adaptation processes will become necessary in order to cope with these challenges in the future. Despite individuals’ and institutions’ willingness to reduce the amount of GHG emissions caused by their actions or their “carbon footprints”, they may lack the knowledge to make effective choices. Carbon calculators have been developed to address these knowledge gaps by measuring and communicating the overall magnitude of the impacts and also the extent to which different behavior patterns contribute to GHG emissions. LCA databases, as...

Food-Chain-Politik – Element einer strategischen Neuorientierung der Agrarpolitik
Provedor de dados: 31
Autores: Reisch,   Lucia A.
European agricultural policy has undergone profound changes during the past decade. The nucleus of this reform has been the transformation of the agricultural and food policy from a producer centred perspective of agriculture to a more market and consumer oriented food chain approach. Such a systemic perspective calls for a stronger and systematic integration of the more demand-oriented policy fields of food, consumer and public health policy as well as of elements of politics of sustainable development along the whole food chain. The paper analyzes the reasons and consequences of these developments, and calls for an integrated “food chain politics” approach. Implications for the future design of practical and academic agricultural policy are drawn.

Provedor de dados: 92
Autores: Laporta,Gabriel Z.; Crivelaro,Thaís B.; Vicentin,Elaine C.; Amaro,Priscila; Branquinho,Maria S.; Sallum,Maria Anice M.
The blood feeding of a population of Cx. nigripalpus from Parque Ecológico do Tietê (PET) was investigated using an indirect ELISA protocol. Mosquitoes were captured outside houses. Five hundred sixteen engorged females collected in a reforested area and 25 in an open area were tested. Rodents and dogs were the most common blood sources, accounting for approximately 65.3% of blood meals. Human blood was detected in 10.9%, dog blood in 26.1%, chicken blood in 2.4%, and rodent blood in 39.2% of the 541 insects tested. ELISA failed in identifying the blood sources of 233 engorged females, indicating that the mosquitoes may have fed on a host which was not tested. One hundred six individuals were positive for more than one host. The unweighted human blood...

Autores: Guerra,Fernando; Trevizam,Anderson Ricardo; Muraoka,Takashi; Marcante,Nericlenes Chaves; Canniatti-Brazaca,Solange Guidolin.
Ingestion of vegetables containing heavy metals is one of the main ways in which these elements enter the human body. Once entered, heavy metals are deposited in bone and fat tissues, overlapping noble minerals. Slowly released into the body, heavy metals can cause an array of diseases. This study aimed to investigate the concentrations of cadmium, nickel, lead, cobalt and chromium in the most frequently consumed foodstuff in the São Paulo State, Brazil and to compare the heavy metal contents with the permissible limits established by the Brazilian legislation. A value of intake of heavy metals in human diets was also calculated to estimate the risk to human health. Vegetable samples were collected at the São Paulo General Warehousing and Centers Company,...
