Most of the literature on this subject is focused on premium prices and consumers’ willingness to pay for local products, since PDO and other labels aim to provide premium incomes for farmers. Our assumption is that PDO drives unexpected changes of farming styles not only related to processing or market strategies but also related to local resources using and to stablishing of different approach to agriculture and food production. We analyzed the PDO Queso Palmero (La Palma cheese) as a case of a dual label system (brand–certification common label) because it gives us the opportunity to compare farmers involved in a PDO scheme with farmers who works outside such systems. We conclude that private brands are more important than common label certification in price formation, but both are complementary, since PDO reinforces farmers’ efforts to improve quality. Beyond premium price, PDO also drives a radical change in farm structures, since it reconnects products to local resources (grazing vs intensification) and redesigns relationships with markets (shortening and diversifying chains and widening product offer). This change is characterized by implementation of new farming strategies in the context of PDO structure that coexist with classical farming strategies closer to intensification, not only in terms of productivity but also in terms of decoupling from local resources and productive and market specialization. Therefore, PDO is a powerful tool for rural development in a wide sense (resilience, empowerment, local capacity and network formation among others) far beyond its narrow remit of promoting economic growth (local or regional). Therefore, the coupling with local resources and the strength of local network and relationships as source of resilience, knowledge and capabilities improvement, have to be included in performance assessment of GIs in order to broaden the appraisal of role in regional development. \u0000Highlights \u0000 \u0000PDO as institution is a powerful tool of farm transformation not only a protection structure of collective heritage or asset. \u0000Private brand effect on price is larger than common label effect (PDO label). \u0000PDO as institution leads radical changes of goat production systems from more production – oriented toward more market – oriented styles. \u0000Market chains and product diversification, focusing on quality, concern about consumers and coupling with local resources are distinctive features of farms involved in PDO. \u0000","PeriodicalId":21210,"journal":{"name":"Revista de la Facultad de Ciencias Agrarias UNCuyo","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81647480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The assessment of TE is currently receiving ever-growing attention as an indicator of sustainability and usage of sufficient natural resources in beekeeping activities. This study aimed to identify the key factors affecting the technical efficiency of bee farms in the province of La Pampa. The study included a sample of 40 bee farms and estimated their TE score through an input-oriented Data Envelopment Analysis (DEA) model. In a second stage, Tobit regression was determined to evaluate the technical inefficiency determinants. This paper found that most beekeeping production units have low TE levels. Only 25 % of bee farms produce either at or close to the frontier. The Tobit model revealed that variables such as marital status, educational level, primary family income, source information usage, planning and health area, affect positively on pure technical efficiency. These results are considered to be of great interest for structured beekeeping systems on small-scale and family farms, as well as for political decision-makers, regarding a public program in apiculture.\u0000Highlights:\u0000\u0000Argentina is the leading country in America, exporting honey worldwide.\u0000DEA approach and Tobit model based on a two-stage analysis is a useful tool when evaluating livestock production systems.\u0000Bee farmers in La Pampa (Argentina) are operating below the production frontier, which indicates there is still scope for improvement.\u0000Variables such as marital status, educational level, primary family income, source information usage, planning and health area, affect positively on technical efficiency.\u0000Beekeepers should be encouraged by the government to improve their efficiency through training programs to ease decision-making and management, therefore enhancing productivity.\u0000","PeriodicalId":21210,"journal":{"name":"Revista de la Facultad de Ciencias Agrarias UNCuyo","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81169141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research is to analyse the social impact of cultural tourism, from the perspective of tradesmen living in the rural municipality of Tlaxcala, Mexico. Information was collected by surveys. Sample size was calculated using the non-probabilistic method (snowball), and 54 tradesmen owning establishments near tourist attractions, were interviewed. Results evidenced that tradesmen do perceive social problems including traffic congestion, increasing living costs, pollution, street vendors, and augmented competition between businesses.

Thus, the present study aimed to identify traits correlated to the fiber length via path analysis under multi-trait BLUP for the cotton breeding. To this end, thirty-six elite lines were evaluated in three environments and phenotyped for many traits related to fiber quality and agronomic traits. Variance components were estimated via residual maximum likelihood (REML). The genetic correlation coefficients among traits were obtained through mixed model output, and to graphically express these results a correlation network was built. Subsequently, we performed path analysis considering fiber length as a principal dependent variable. Genetic parameters obtained by multi-trait BLUP model indicate that the phenotypic variance for most traits is mostly composed of residual effects, which reinforces the need for using more accurate statistical methods such as multi-trait BLUP. The results found for genetic correlations and path analysis under multi-trait BLUP reveal the difficulty of selection based on important fiber quality traits, especially fiber length, since most traits show very low cause-and-effect relationship, and other important traits present undesirable cause-and-effect relationship. \u0000Highlights \u0000 \u0000Multiple-trait BLUP is the most appropriate method to predict genetic values. \u0000This is the first study in cotton to perform path analysis under multiple-trait BLUP. \u0000The findings of this study indicate that there is no genotype presenting all desirable traits. \u0000","PeriodicalId":21210,"journal":{"name":"Revista de la Facultad de Ciencias Agrarias UNCuyo","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90675383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A decreasing linear effect of urea levels on effluent losses in corn silages was observed. In parallel, an increasing linear effect of urea levels on pH, increasing from 3.49 to 4.12 in silages without urea in relation to silages with the maximum urea level, was also observed.
