Consumers’ Willingness to Pay for Food Safety in Nairobi: The Case of Fresh Vegetables

Large urban areas in developing countries represent currently the most dynamically growing markets for food products. This study investigates the willingness to pay of consumers in Nairobi for safer leafy vegetables. We survey individuals’ perceived food safety across four major market categories, while also considering the explanatory role of trust and behavioral, psychological, and socio-demographic covariates. Results show that willingness to pay is market-specific and multi-faceted, with trust and perceived risks as important drivers, while income plays only a subordinate role. We conclude that policy makers should aim to reduce asymmetric information within the value chain without raising food prices such that safer vegetables would become unaffordable for the poor.Food safety, perceived risk, willingness to pay, regression tree, urban agriculture, Crop Production/Industries, Food Consumption/Nutrition/Food Safety,

Tracing the geographical origin of Argentinean lemon juices based on trace element profiles using advanced chemometric techniques

This study examines the application of chemometric techniques associated with trace element concentrations for origin evaluation of lemon juice samples. Seventy-four lemon juice samples from three different provinces of Argentina were evaluated according to their microelement contents to identify differences in patterns of elements in the three provinces. Inductively coupled plasma mass spectrometry (ICP-MS) was used for the determination of twenty-five elements (Ag, Al, As, Ba, Bi, Co, Cr, Cu, Fe, Ga, In, La, Li, Mn, Mo, Ni, Rb, Sb, Sc, Se, Sn, Sr, Tl, V, and Zn). Once the analytical data were collected, supervised pattern recognition techniques were applied to construct classification/discrimination rules to predict the origin of samples on the basis of their profiles of trace elements. Namely, linear discriminant analysis (LDA), partial least square discriminant analysis (PLS-DA), k-nearest neighbors (k-NN), random forest (RF), and support vector machine with radial basis function Kernel (SVM). The results indicated that it was feasible to attribute unknown lemon juice samples to its geographical origin. SVM had better performance compared to RF, k-NN, LDA and PLS-DA, listed in descending order. Eventually, this study verifies that trace element pattern is a powerful geographical indicator when identifying the origin of lemon juice samples by analyzing trace element data with the help of SVM technique. This level of accuracy provides an interesting foundation to propose the combination of trace element contents with SVM technique as a valuable tool to evaluate the geographical origin of lemon juice samples produced in Argentina.Fil: Gaiad, José Emilio.

Consumer Demand for Quality: Major Determinant for Agricultural and Food Trade in the Future?

The impact of consumer demand for quality on the agricultural and food system is an increased emphasis on quality differentiation but not all in the direction of upgrading quality. The more elite market segments are thriving and reaching growing numbers of consumers but the basic price/quality markets remain strong. Most recent economic studies find that consumers are willing to pay for food safety and other quality attributes, and for information about them. The magnitude of the valuations varies by food product, attribute, country, and study design. This literature and a case study of genetically modified foods suggest that consumer demand has a strong effect on agricultural and food trade.food quality, food safety, consumer demand, willingness to pay, international trade

Dynamics in crop protection, agriculture and the food chain in Europe

Overview on the vital role of plant protection in Europe in maintaining and enhancing the dynamics of agricultural production and the food chain. The report offers an overview of the achievements of more sustainable production methods in European agriculture, and the actions taken by the farming community in response to private market initiatives and public policies. Such actions establish new farming systems. The report offers factual information, as well as analyses to put trends in context

Meat safety as a tool of differentiation for retailers: Spanish and French examples of meat "supply chain brands"

The purpose of this article is to analyse how the health crises have contributed to increasing the segmentation of the supply of fresh and little-processed food products under the impetus of a reinforcement of regulations (affecting the supply chain as a whole) and of strategies adopted by the stakeholders. Indeed, since several food crises have strongly affected the production of animal food products, food safety has become one of the most important aspects of quality products for both consumers and retailers. The authors carry out an empirical and comparative analysis of the reactions of two neighbouring countries (Spain and France) faced with major health crises caused by similar events: the emergence of BSE cases. A special focus is made on the initiatives taken privately by two French retail groups (Carrefour and Auchan) operating in both countries. The analysis shows that retailers have developed systems of quality insurance developed in order to reduce uncertainty and to restore consumers’ confidence in the quality of the products they buy. These programmes of actions pave the way for policies of product differentiation. In a relatively different context from that of France, the two big French retail groups Carrefour and Auchan operating in Spain have developed similar approaches, which had not been the case in France. The paper provide useful keys for a better understanding of the strategies of retailers (use of "supply chain brands" as tools of differentiation to ensure consumers’ loyalty, marketing communication) in a context of sharp competition and of relative dissatisfaction with respect to «minimum quality» standards. \u

Consumer attitude and behaviour towards 'Flandria' quality labelled tomatoes

In recent years, trust in food safety and food quality has decreased as a result of consecutive food crises. Consequently, numerous quality labels signalling credence characteristics have been established. One of these labels is the Belgian Flandria label for fresh fruit and vegetables. Based on a self-administered consumer survey (n=373), this paper addresses questions about consumer attitudes, behaviour and perception towards tomatoes in general, and the Flandria tomato label in particular. Principal component analysis and consumer segmentation are performed. The findings indicate that the Flandria label may have become the new standard for tomatoes and may have lost a major part of its differentiation potential by being positioned "in the middle" and being too intensively used for a wide range of other fruits and vegetables

The influence of country of origin on German consumer preferences for peaches: a latent class choice model

Germany is an important world level market for fresh fruit. Spain and Italy are the main suppliers of fresh fruit on the German market while the main imported products are apple, grapes, peaches and oranges. The aim of this paper is to assess the role country of origin plays in the preferences of German consumers for peaches. Since German legislation requires fresh fruit sold on the market to clearly display the product’s country of origin, German consumers usually make their choice with this information to hand. How important is such information, and what is the trade-off between country of origin and price or organic production system? We attempted to investigate such concerns through a choice experiment approach conducted by means of a questionnaire-based survey administered to a representative sample of 300 German households. In the experiment, respondents were asked to choose their favorite peach among four alternatives. Each peach was described as imported from four specific countries (Italy, Spain, Turkey and France) and available at a specific price; some of the peaches were certified Organic or PDO. The stated choices are analyzed using a latent class choice model to derive estimates of preferences for peaches. Results indicate the presence of three distinct consumer segments in the German peach market. The largest segment (48%) showed a strong preference for Italian peaches as well as for organic and PDO certification. For this segment, price was not an important attribute. The second segment (41%) showed a strong preference for Spanish produce and organic certification. Price was important in this case. The third segment (11%) had a negative preference for Italian and Spanish peaches, with price being the main attribute.Germany peach market, consumer preferences, latent class choice models, Agricultural and Food Policy,

Monitoring land use changes using geo-information : possibilities, methods and adapted techniques

Monitoring land use with geographical databases is widely used in decision-making. This report presents the possibilities, methods and adapted techniques using geo-information in monitoring land use changes. The municipality of Soest was chosen as study area and three national land use databases, viz. Top10Vector, CBS land use statistics and LGN, were used. The restrictions of geo-information for monitoring land use changes are indicated. New methods and adapted techniques improve the monitoring result considerably. Providers of geo-information, however, should coordinate on update frequencies, semantic content and spatial resolution to allow better possibilities of monitoring land use by combining data sets
