A financial training program designed by Cooperative Extension specialists was provided to over 2,000 USDA/FSA borrowers from the Northeast during the period 1994-1999. Key to the success of the workshops was an in-depth, user-friendly curriculum that evolved over time, eventually replacing satellite-feed instruction with pre-taped videos. Cluster analysis classified nearly 70 percent of workshop participants as "Low Finance Priority" or "Low Finance Knowledge." Farmers in these clusters received a relatively greater educational benefit from the program than those not in these clusters.. Impact analysis indicated that perceived annual gain in farm net worth from application of workshop tools ranged from approximately $5,000 to $10,000. The training...

Non-tariff measures (NTMs) are playing an increasing role in international trade of agri-food trade. Although well-recognized, this aspect has not been extensively analysed at a disaggregated product level. This paper presents a quantitative analysis of the trade incidence of NTMs notified by OECD countries on 777 products and clusters these products according to three trade indicators. While the ‘protection for sale’ literature provides useful explanations, it is not completely satisfying in resolving the puzzle of cross-product differences in the occurrence of NTMs.

The objectives of this paper are to examine consumers' perceptions of Protected Designation of Origin (PDO) beef on the basis of a survey of consumers and buyers of beef. The paper identifies a profile of PDO beef consumers, examines their behaviour and perceptions on PDO beef, derives the dimensions of perceptions of PDO beef, and establishes segments based upon those dimensions. The results reveal that PDO consumers are representative of all geographical regions, age and profession groups, are lighter consumers of beef and shop for food mainly in the butchers. Consumers' perceptions on PDO beef emphasises quality, safety, and control. However, underlying those perceptions are six main dimensions and it is possible to identify three segments of PDO beef...

Tanulmányunkban 1000 fős országos felmérés eredményei alapján azonosítottuk a hazai munkahelyi étkezés fogyasztói szegmenseit. Bebizonyítottuk, hogy a célcsoportok szocio-demográfiai ismérvek mellett az étkezési és élelmezési szokások, a munkahelyi étkezéshez való viszony szerint is eltéréseket mutatnak, amely igazolja, hogy ezen ismérvek befolyásolják az egyént abban, hogy milyen munkahelyi étkezési formát választ. Megállapítható, hogy a munkahelyi étkezés igénybevétele leginkább az időtudatos élelmiszer-fogyasztói magatartással függ össze, de megjelennek a kényelem, a termékminőség és a kiegészítő szolgáltatások iránti fogyasztói elvárások is. Az eredmények segítséget jelenthetnek a piacfejlesztési, piacbővítési lehetőségek definiálásában és a célpiaci...

Subsistence and Semi-subsistence Farming in Selected EU New Member States

Davidova, Sophia; Fredriksson, Lena; Bailey, Alastair.

Factor and cluster analysis are used to analyse the attitudes and perceptions of agricultural households in five EU New Member States towards farming, commercialisation, and barriers to and drivers for an increased integration in agricultural markets. The contribution of unsold output to the total household income is valued. A stepwise linear regression is employed to detect important variables explaining the degree of agricultural market integration of farm households. The analysis indicates that subsistence farming is of utmost importance for the rural poor, and particularly in Bulgaria and Romania. The proportion of consumption from own production, manual cultivation techniques and distance to an urban centre negatively affect output sales. Rural...

The European and Italian food system is experiencing a change in the relationship with the consumer and with the distribution. In fact, customers are increasingly demanding, and are attracted, by products that have high quality content and a strong link with the territory. The brands with the price are the two factors affecting the strategic policies of the food producer firms. At the same time, the retail system has proven to be very sensitive to consumer demands by providing quality products at competitive prices and using their brand as an element of loyalty. In the European context, the Italian agri-food system has the higher number of products with the Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) recognition....

An important issue in WTO trade negotiations is whether further liberalization of trade and agricultural policies may help or hinder food security in WTO member countries, especially the developing countries. The WTO recognizes various classifications of countries: developed, developing, least developed (LDC) and net food importing developing (NFIDC). How well do these categories capture issues of food security? This paper employs various methods of cluster analysis (including an approach based on fuzzy sets) and data for 167 countries to identify groups of countries categorized according to five measures of food security: food production per capita, the ratio of total exports to food imports, calories per capita, protein per capita, and the share of the...

The Demand for Meats in Indonesia: A Censored Regression Approach

Hutasuhut, Maradoli; O'Donnell, Christopher J.; Chang, Hui-Shung (Christie); Griffith, Garry R.; Doran, Howard E..

In this study, meat consumption and socio-demographic data from the 1990, 1993 and 1996 SUSENAS Household Food Expenditure and Consumption Surveys were employed to estimate the demand for meats in Indonesia. The provinces of DKI Jakarta and West Java were chosen as the areas of study because of the population, level of meat consumption and the availability and quality of information in these two provinces. Several statistical and econometric procedures were performed. Firstly, a cluster analysis (Nicol, 1991) was used to aggregate the 16 meat types recorded in the SUSENAS into four Meat Groups (MG-1, 2, 3 and 4). Secondly, a double truncation procedure was used to estimate the linear approximation of the Almost Ideal Demand System (LA/AIDS) because of the...

TYPOLOGY OF RURAL AREAS IN THE CENTRAL AND EASTERN EUROPEAN EU NEW MEMBER STATES

Baum, Sabine; Trapp, Christian; Weingarten, Peter.

Rural areas in Central and Eastern Europe are very often associated with a backwardness in terms of income and employment opportunities, a high dependency on agriculture, the out-migration of young, skilled people, a low population density and an insufficient infrastructure. In this paper 3 typologies are presented, which show that rural areas cannot be considered homogeneous and not all of them need the same developmental measures. The first typology classified all NUTS-3 regions in the ten Central and Eastern European countries (CEEC-10) by means of cluster analysis according to 7 demographic and socio-economic criteria. The result revealed 5 different types of regions as most adequate: three are largely rural, one includes both rural, and especially...

PRODUCER SEGMENTATION AND THE ROLE OF LONG-TERM RELATIONSHIP IN MALAYSIA’S MILK SUPPLY CHAINS

Boniface, Bonaventure.

Research on buyer-seller relationships in the agricultural sector receives little attention. A growing body of evidence suggests that strong buyer-seller relationships facilitate more efficient supply chains. The long term relationship literature tends to treat suppliers as a homogenous group when attempting to identify motivations, strategies and incentives to enhance the quality of buyer-seller relationships. This article explores the role of long-term relationships between buyers and sellers in Malaysia’s dairy industry, taking into consideration the heterogeneous nature of the producers. Interviews with 133 producers provide the data for this study. Cluster analysis suggests two well-defined groups differing in terms of demographic characteristics and...

ABSTRACT Chinese indigenous chicken breeds are geographically widespread, and a total of 116 indigenous chicken breeds are listed as Chinese national genetic resources. However, these indigenous chicken breeds are facing serious challenges as declining population and germplasm degeneration because lots of commercial chicken breeds had been introduced. In this study, the genetic variations of eleven Chinese indigenous chicken breeds of Sichuan province and three commercial chicken breeds were investigated based on the partial mitochondrial DNA D-loop of 487bp in length. 147 individuals from 14 breeds were examined and 34 haplotypes were observed. Genetic diversity analysis showed that the highest haplotype diversity level was found in Dahen Chicken (DH)...

This study aimed: 1) to classify ingredients according to the digestible amino acid (AA) profile; 2) to determine ingredients with AA profile closer to the ideal for broiler chickens; and 3) to compare digestible AA profiles from simulated diets with the ideal protein profile. The digestible AA levels of 30 ingredients were compiled from the literature and presented as percentages of lysine according to the ideal protein concept. Cluster and principal component analyses (exploratory analyses) were used to compose and describe groups of ingredients according to AA profiles. Four ingredient groups were identified by cluster analysis, and the classification of the ingredients within each of these groups was obtained from a principal component analysis,...

The agricultural potential is generally assessed and managed based on a one-dimensional vision of the soil profile, however, the increased appreciation of sustainable production has stimulated studies on faster and more accurate evaluation techniques and methods of the agricultural potential on detailed scales. The objective of this study was to investigate the possibility of using soil magnetic susceptibility for the identification of landscape segments on a detailed scale in the region of Jaboticabal, São Paulo State. The studied area has two slope curvatures: linear and concave, subdivided into three landscape segments: upper slope (US, concave), middle slope (MS, linear) and lower slope (LS, linear). In each of these segments, 20 points were randomly...

ABSTRACT Fruits from 86 ecotypes of Mexican plum were harvested from the states of Guerrero and Morelos during the dry season. Of these, 22 were wild ecotypes and 64 were cultivated varieties. Among the variables measured, those with the highest variation coefficients were color, flavor, and mass (> 45%), highlighting the presence of considerable intra-species variability. Cluster analysis separated the 86 accessions into 5 groups, mainly on the basis of color, flavor, length, and mass. Members from the first three groups had red (Group I), yellow (Group II), or purple (Group III) epicarps and higher values of mass (12.2-16 g), length (29.6-33.9 mm), pulp yield (68.8-71.9% ), TSS (11.16-11.52 °Brix) and flavor index (14.5-18.3), making them suitable...

In the present study, alternative and traditional nonlinear models to describe growth curves of Morada Nova sheep reared in the state of Bahia, Brazil, were applied. The nonlinear models were: Schnute, Mitscherlich, Gompertz, Logistic, Meloun I Meloun II, III Meloun, Gamito and Meloun IV. The model adjustment was evaluated by using: Adjusted Coefficient of Determination (R²aj), Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), Mean Squared Error of Prediction (MEP) and Coefficient of Determination of Prediction (R²p). The selection of the best model was based on cluster analysis, using the evaluators as variables. Six out of the nine tested models converged, while Meloun I and Meloun IV were equally effective in explaining animal...

ABSTRACT The present study was carried out to evaluate the phenotypic diversity between fighting cocks; roosters of the naturalized ecotypes Graúna Dourada, Brejeira, Teresina, and Nordestina; roosters of the Sertaneja genetic (synthetic) group; and family-farmed roosters via descriptive and multivariate analyses. The qualitative traits evaluated by descriptive analysis indicated a prevalence of single comb in the Graúna Dourada, Teresina, Nordestina, and Sertaneja ecotypes, whereas the Brejeira ecotype, fighting cocks, and family-farmed roosters have a pea-type comb, which can be viewed as a sign of introgression of the fighting cock in flocks of the region. Dark plumage prevailed across the groups. The quantitative traits subjected to multivariate...
