Tipificación y caracterización de café comercial mediante métodos instrumentales y quimiometría.
Provedor de dados: 32
Autores: Vázquez Hernández, Lorena.
El control de calidad de los productos agroalimentarios está basado en su  caracterización bioquímica, como una de las partes esenciales. Para el caso del café, la composición química está fuertemente relacionada con las condiciones agroecológicas (suelo, clima, altura, etc.) de cada una de las regiones productoras. El café es la segunda materia prima en importancia en el mercado nacional, por lo cual, la calidad es importante para este producto. Para asegurarnos de la calidad del café tanto para los consumidores como productores existe la necesidad de establecer métodos analíticos, rápidos, objetivos y sensitivos. Para realizar la caracterización del café comercial existen métodos convencionales establecidos en la Norma Mexicana (NMX-F-013-SCFI-2000),...

Colonización micorrízica y diversidad de hongos micorrízicos de algunas especies de orquídeas epifitas tropicales en el Sureste de Chiapas, México
Provedor de dados: 32
Autores: Cruz Blasi, Jesús.
El status de la colonización micorrízica, los factores que la influyen y la diversidad fúngica  asociada, fue investigada en orquídeas de hábitos epifitos que crecen en las ramitas de los  cafetales y en árboles remanentes de la selva tropical del Sureste de México. El 97% de los  individuos presentaron algún grado de colonización micorrízica. La intensidad de colonización  estuvo inversamente relacionada con el diámetro de la raíz. Orquídeas de raíces delgadas  estuvieron intensamente colonizadas, alcanzando en algunos casos hasta 98%. Así también,  existió una relación positiva entre la edad de las raíces y su intensidad de colonización. Las  raíces más viejas concentraron la mayor colonización. En términos generales, las células  recién colonizadas se...

Responding to Globalization: Impacts of Certification on Colombian Small-Scale Coffee Growers
Provedor de dados: 7
Autores: Rueda, Ximena; Department of Environmental Earth System Science, School of Earth Sciences, Stanford University; School of Management, Universidad de los Andes; xrueda@alum.mit.edu.
Eco-certification of food and other agricultural products has been promoted as a way of making markets work for sustainability. Certification programs offer a price premium to producers who invest in more sustainable practices. The literature on the impacts of certification has focused primarily on the economic benefits farmers perceive from participating in these schemes. These benefits, however, are often subject to price variability, offering only a partial explanation of why farmers join and stay in certification programs. We evaluated the potential of the Rainforest Alliance certification program to foster more resilient social-ecological systems in the face of globalization. Using the case of Santander, Colombia, and a pair-based comparison of 86...

Viability in protoplasts and cell suspensions of Coffea arabica cv. Catimor
Provedor de dados: 69
Autores: Fernandez-Da Silva,Rafael; Menéndez-Yuffá,Andrea.
Two methods were evaluated in order to assess the viability of protoplasts and cell suspensions of Coffea arabica cv. Catimor used in a protocol of transformation by electroporation. One method consisted of staining with 1 % Evans blue and the other staining with 1% 3-[4,5-dimethyltiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT). When Evans blue was applied to viable cells and protoplasts they either did not stain or acquired a faint blue colour. However, it was difficult to distinguish the non-viable cells in the wide spectrum of clear blue tonalities. In contrast, with the MTT assay only the viable cells and protoplasts reduced this salt to the red coloured formazan; viable and non-viable cells were distinguished more clearly with MTT than with Evans...

RELATIONSHIP BETWEEN COFFEE CROP PRODUCTIVITY AND VEGETATION INDEXES DERIVED FROM OLI / LANDSAT-8 SENSOR DATA WITH AND WITHOUT TOPOGRAPHIC CORRECTION
Provedor de dados: 70
Autores: Nogueira,Sulimar M. C.; Moreira,Maurício A.; Volpato,Margarete M. L.
ABSTRACT The reflectance values of a coffee crop are influenced by several factors such as planting direction, crop spacing, time of the year, plant age and topography which reduces the accuracy of the estimates derived from remote sensing data. In this context were evaluated the relationships between coffee productivity and values of NDVI, SAVI and NDWI vegetation indexes with and without topographic reflectance correction for different coffee phenological phases for the crop years 2013/2014 (low productivity) and 2014/2015 (high productivity). The evaluations were made through the standard deviation of vegetation indices (VIs), linear relationship between the cosine factor and the VIs and between VIs and coffee productivity. The best phenological phases...

Provedor de dados: 70
Autores: Muner,Lúcio H. de; Masera,Omar; Fornazier,Maurício J.; Souza,Cássio V. de; Loreto,Maria Das D. S. de.
Three growing systems of Arabica coffee were evaluated under the energy perspective, in the state of Espírito Santo in Brazil. The systems are conventional cultivation (CC), cultivation with good agricultural practices (CGP) and organic farming (OF). It was made a comparison of the energy flows within these three systems to show sustainable levels of each one based on production average data of several family-farming units. Therefore, we analyzed crop yield, total energy efficiency reverse (TEER), energy efficiency of ripe coffee (EERC) and non-renewable energy efficiency (NREE). OF system had values for TEER, EERC and NREE of 3.3 4.7 and 7.9 respectively. Yet CC showed values of 1.8, 1.9 and 1.6 for TEER, EERC and NREE respectively. Furthermore, CGP...

Leaf-associated bacterial microbiota of coffee and its correlation with manganese and calcium levels on leaves
Provedor de dados: 74
Autores: Sousa,Leandro Pio de; Silva,Marcio José da; Costa Mondego,Jorge Maurício.
Abstract Coffee is one of the most valuable agricultural commodities and the plants’ leaves are the primary site of infection for most coffee diseases, such as the devastating coffee leaf rust. Therefore, the use of bacterial microbiota that inhabits coffee leaves to fight infections could be an alternative agricultural method to protect against coffee diseases. Here, we report the leaf-associated bacteria in three coffee genotypes over the course of a year, with the aim to determine the diversity of bacterial microbiota. The results indicate a prevalence of Enterobacteriales in Coffea canephora, Pseudomonadales in C. arabica ‘Obatã’, and an intriguing lack of bacterial dominance in C. arabica ‘Catuaí’. Using PERMANOVA analyses, we assessed the association...

Provedor de dados: 74
Autores: Loss-Morais,Guilherme; Ferreira,Daniela C.R.; Margis,Rogério; Alves-Ferreira,Márcio; Corrêa,Régis L.
As microRNAs (miRNAs) are important regulators of many biological processes, a series of small RNAomes from plants have been produced in the last decade. However, miRNA data from several groups of plants are still lacking, including some economically important crops. Here microRNAs from Coffea canephora leaves were profiled and 58 unique sequences belonging to 33 families were found, including two novel microRNAs that have never been described before in plants. Some of the microRNA sequences were also identified in Coffea arabica that, together with C. canephora, correspond to the two major sources of coffee production in the world. The targets of almost all miRNAs were also predicted on coffee expressed sequences. This is the first report of novel miRNAs...

Provedor de dados: 74
Autores: Vieira,Elisa S.N.; Von Pinho,Édila V. de R.; Carvalho,Maria G.G.; Esselink,Danny G.; Vosman,Ben.
Microsatellite markers, also known as SSRs (Simple Sequence Repeats), have proved to be excellent tools for identifying variety and determining genetic relationships. A set of 127 SSR markers was used to analyze genetic similarity in twenty five Coffea arabica varieties. These were composed of nineteen commercially important Brazilians and six interspecific hybrids of Coffea arabica, Coffea canephora and Coffea liberica. The set used comprised 52 newly developed SSR markers derived from microsatellite enriched libraries, 56 designed on the basis of coffee SSR sequences available from public databases, 6 already published, and 13 universal chloroplast microsatellite markers. Only 22 were polymorphic, these detecting 2-7 alleles per marker, an average of...

Increased synthesis of galactinol and raffinose family oligosaccharides (RFOs) has been reported in vegetative tissues in response to a range of abiotic stresses. In this work, we evaluated the transcriptional profile of a Coffea canephora galactinol synthase gene (CcGolS1) in two clones that differed in tolerance to water deficit in order to assess the contribution of this gene to drought tolerance. The expression of CcGolS1 in leaves was differentially regulated by water deficit, depending on the intensity of stress and the genotype. In clone 109A (drought-susceptible), the abundance of CcGolS1 transcripts decreased upon exposure to drought, reaching minimum values during recovery from severe water deficit and stress. In contrast, CcGolS1 gene expression...

Altered expression of the caffeine synthase gene in a naturally caffeine-free mutant of Coffea arabica
Provedor de dados: 74
Autores: Maluf,Mirian Perez; Silva,Carla Cristina da; Oliveira,Michelle de Paula Abreu de; Tavares,Aline Gomes; Silvarolla,Maria Bernadete; Guerreiro Filho,Oliveiro.
In this work, we studied the biosynthesis of caffeine by examining the expression of genes involved in this biosynthetic pathway in coffee fruits containing normal or low levels of this substance. The amplification of gene-specific transcripts during fruit development revealed that low-caffeine fruits had a lower expression of the theobromine synthase and caffeine synthase genes and also contained an extra transcript of the caffeine synthase gene. This extra transcript contained only part of exon 1 and all of exon 3. The sequence of the mutant caffeine synthase gene revealed the substitution of isoleucine for valine in the enzyme active site that probably interfered with enzymatic activity. These findings indicate that the absence of caffeine in these...

Genome-wide identification, classification and transcriptional analysis of nitrate and ammonium transporters in Coffea
Provedor de dados: 74
Autores: Santos,Tiago Benedito dos; Lima,Joni Esrom; Felicio,Mariane Silva; Soares,João Danillo Moura; Domingues,Douglas Silva.
Abstract Nitrogen (N) is quantitatively the main nutrient required by coffee plants, with acquisition mainly by the roots and mostly exported to coffee beans. Nitrate (NO3–) and ammonium (NH4+) are the most important inorganic sources for N uptake. Several N transporters encoded by different gene families mediate the uptake of these compounds. They have an important role in source preference for N uptake in the root system. In this study, we performed a genome-wide analysis, including in silico expression and phylogenetic analyses of AMT1, AMT2, NRT1/PTR, and NRT2 transporters in the recently sequenced Coffea canephora genome. We analyzed the expression of six selected transporters in Coffea arabica roots submitted to N deficiency. N source preference was...

Autores: OLIVEIRA, V. H. de; CAMPOS, I. S.; CARDOSO, J. E.; SALES, F. de.
A utilização de culturas de ciclo curto em cafezais novos visa principalmente reduzir seus custos de formação, garantir um melhor aproveitamento do solo, além de assegurar ao produtor um retorno do capital investido, antes da primeira colheita. Prática cultural bastante difundida na agricultura acreana, o cultivo intercalar, no entanto, ainda não dispõe de suficientes informações técnicas locais que permitam recomendá-la, de modo racional, ao produtor. Em consequência, o seu emprego tem causado, na maioria dos casos, danos que afetam a produção e produtividade do cafeeiro. Com a finalidade de obter dados para a solução desse problema, estão sendo conduzidos nos campos experimentais da Fazenda EMBRAPA, km 14 da BR-364, município de Rio Branco, experimentos...

A regiao do Nordeste Mineiro e a quarta maior regiao produtora de cafe do Cerrado. Seu cafe tem sido considerado de ma qualidade devido ao despreparo ou falta de tecnica de alguns pequenos e medios produtores no processo de pos-colheita. Levando-se em conta o baixo preco da terra, a facilidade de contratar mao-de-obra e as condicoes edafoclimaticas, essa regiao podera tornar-se uma das maiores produtoras de cafe do Pais. Compreende tres Polos de influencia: Teofilo Otoni, abrangendo dezoito municipios e um milhao de hectares, caracteriza-se por ter grandes cafeicultores. O cafe e a principal cultura e, talvez, unica atividade agricola em escala comercial; Capelinha com dezesseis municipios numa area de 1,6 milhoes de hectares. Nesse polo predominam medios...

RESUMO: O nitrogênio (N) é um dos macronutrientes mais exigidos pelo cafeeiro. Sua utilização é necessaria para o cultivo nos solos de cerrado, pois estes não fornecem o nutriente em quantidades suficientes. Foi realizado um ensaio com o objetivo de estudar o efeito de fontes e doses de N no café decotado a 1,5 m de altura em 1997. O experimento foi instalado num Latossolo Vermelho na área experimental da Embrapa Cerrados, em Planaltina -DF. Os tratamentos foram constituídos de 0, 200, e 600 kg ha-¹ de N na forma de uréia parcelados em frações de 1/4, 1/2 e 3/4 no primeiro ano e em 3/4, 1/2 e 1/4 fornecidos no segundo ano e repetidos respectivamente, no terceiro e quarto anos.

Provedor de dados: 82
Autores: Venzon,Madelaine; Rosado,Maria C.; Euzébio,Denise E.; Souza,Brígida; Schoereder,José H.
Diversification of crops with species that provide suitable pollen for predators may reduce pest population on crops by enhancing predator effectiveness. In this paper we evaluated the suitability of leguminous cover crop pollens to the predatory green lacewing Chrysoperla externa (Hagen). The predator is commonly found in coffee agroecosystems and the plant species tested were pigeon pea and sunn hemp, which are used in organic coffee systems. Newly emerged females and males of C. externa were reared on diets containing pollen of pigeon pea, sunn hemp, or castor bean, used as a control. The reproductive success of C. externa was evaluated when females fed the pollen species and when honey was added to the diets, to verify the predator need for an extra...

Abstract: The objective of this work was to evaluate the concentrations and accumulation of macronutrients in conilon coffee (Coffea canephora) fruit, and their concentrations in leaves, over two years, in irrigated and nonirrigated coffee plants. Three-year-old conilon coffee plants of the cultivar Emcapa 8111 genotype 02 were used. An experimental design was carried out in randomized complete blocks, in a split-plot arrangement, with 14 replicates. The main plot factor was irrigation versus nonirrigation of coffee plants, and the split-plot factor was different fruit and leaf collection times. Collections began 10 days after the beginning of flowering and were performed on average every 28 days, until full fruit ripening. At each sampling date, five...

Decaffeinated? Situation, Trends, and Prospects for Smallholder Coffee Production in Rwanda
Provedor de dados: 31
Autores: Loveridge,   Scott; Nyarwaya,   Jean Baptiste; Shingiro,   Emmanuel.
Most Rwandan coffee is currently grown and processed the same way it was a decade ago.  Consequently, Rwanda’s coffee production and marketing system has not been able to keep up with  changes in the global market for high quality coffee. Given world market gluts of relatively poor quality coffee, Rwanda is now exporting a product that fetches low prices. Despite the challenges in coffee marketing and production, coffee remains one of Rwanda’s most important official sources of foreign exchange and the drop in production is of major concern to both the public and private sectors. In an effort to assist decision makers in the coffee sector better understand factors affecting farmers’ production decisions and their attitudes about coffee, the FSRP fielded a...

Do Farmers Benefit from Participating in Specialty Markets and Cooperatives? The Case of Coffee Marketing in Costa Rica
Provedor de dados: 31
Autores: Wollni,   Meike; Zeller,   Manfred.
Historically low prices in the conventional coffee market have caused financial and social hardship among coffee farmers. In the face of this crisis, specialty markets have attracted the attention of the international donor community. These market segments have shown consistent growth over the last decade and exhibit price premiums in international markets. Therefore, if higher prices are passed on to farmers, access to specialty markets could help to alleviate the crisis brought on by low prices in the conventional sector. The present study attempts to identify the factors that determine farmers' participation in specialized markets and whether participation in these markets leads to higher prices for farmers. A two-stage model is used to analyze farmers'...

Justified hopes or utopian thinking? The suitability of coffee certification schemes as a business model for small-scale producers
Provedor de dados: 31
Autores: Beuchelt,   Tina; Zeller,   Manfred; Oberthur,   Thomas.
The marketing of coffee through group-based, certified market channels is often promoted by governments and donors as a viable business model for poor small-scale farmers. Organic and fairtrade coffees have become very popular among socially, environmentally and health conscious consumers in recent years. While coffee certification programs have been in place for over fifteen years, there are few studies on the welfare impacts of certification schemes. Therefore, this research seeks to analyse the impacts of certification on poverty alleviation and to identify the critical factors which explain success or failure of certification schemes. We use a combination of qualitative and quantitative research, comparing small-scale coffee producers in northern...

TRADE-OFFS BETWEEN ECONOMIC EFFICIENCY AND CONTAMINATION BY COFFEE PROCESSING A BIOECONOMIC MODEL AT THE WATERSHED LEVEL IN HONDURAS
Provedor de dados: 31
Autores: Barbier,   Bruno; Hearne,   Robert R.; Gonzalez,   Jose Manuel; Nelson,   Andy; Castaneda,   Orlando Mejia.
In Honduras, traditional coffee processing is the cause of two major problems: poor coffee quality and contaminated water.  In this paper we present a method that determines the trade-off between economic efficiency and contamination in a Honduran sub-watershed.  The method is a bioeconomic model based on mathematical programming that stimulates the functioning of the interlinked economic and ecological processes in the sub-watershed.  We compare various scenarii where the model is given the possibility of replacing traditional coffee processing plants with a network of improved ecological plants.  For different levels of contamination the model determines the optimal location and size of new coffee processing plants along river streams by minimizing...

The formation of agricultural stock has the important paper of softening the seasonal impacts, lessening the discrepancy among the prices in the harvest and time between harvests, contributing, like this, with the stabilization of the price. In that sense, the present article aimed at to analyze the financial viability in the Arabic stockpiling of coffee in the area of Viçosa -MG, being obtained for that the return and the stockpiling risk for every month of the year. In agreement with the results, the stockpiling of the coffee is a strategy financially viable, being a factor in the elevation of the return and decrease of the risk level, especially in what he/she concerns the stockpiling in the period of 8, 9 and 10 months and the sale of the coffee in...

Geographical Indications and the Value of Reputation - Empirical Evidence for Cafe de Marcala
Provedor de dados: 31
Autores: Teuber,   Ramona.
More and more coffee-producing countries establish geographical indications (GIs) for their coffees. GIs are not only considered to be a useful tool for protecting an established reputation against misuse by imitators but also being a useful strategic tool to enter the growing specialty coffee market. Whereas the importance of regional reputation is quite well-documented in the empirical literature on wine, empirical evidence for regional reputational effects on coffee prices is rather scarce. Hence, the objective of the present paper is to shed light on the relevance of regional reputation in the coffee market by representing results for Honduran coffees. A hedonic pricing model based on internet auction data is presented including current quality proxied...

Autores: Pereira,   Vanessa da Fonseca; Mendonca,   Talles Girardi de; Reis,   Bricio dos Santos.
Due to growing consumer demands regarding product quality and the social and environmental aspects of the production process, there is a need to redefine the agricultural productive structure so as to make it sustainable. The Integrated Production System in Coffee (CIP) aims to meet these new requirement standards. The system, however, is still very recent and requires more detailed studies to identify its strengths and weaknesses. Therefore, the objective of this work is to carry out a comparative analysis of the economic viability and the risk associated to the conventional and integrated systems of coffee production in the farm property of São João, in the Coimbra district in Minas Gerais state. The method used was the calculation of the viability and...

What is the Difference in Profit per Acre between Organic and Conventional Coffee?
Provedor de dados: 31
Autores: Jensen,   Jennifer; Dicks,   Michael R.
The research addresses the economic problem of deforestation.  A contributing factor to deforestation is coffee production. Coffee is an indigenous plant that is naturally occurring in the native tropical forests. However, conventional coffee is grown on cleared forest soil. In the native forest there is the potential for additional fruits (bananas, mangoes, avocados) and wood products while in the conventional coffee production system the only product is coffee.  Conventional coffee production often causes deforestation and soil erosion while the organic coffee production system does not. In addition, the price risk associated with the coffee monoculture is high and has proven disastrous to the sustainability of coffee production in past years. Thus,...

Do retail coffee prices increase faster than they fall? Asymmetric price transmission in France, Germany and the United States
Provedor de dados: 31
Autores: Gomez,   Miguel I.; Koerner,   Julia.
This investigation examines price transmission asymmetries (PTA) between international and retail coffee prices in the US, France and Germany. Differences in price transmission mechanisms provide evidence for disparities in market structure and market performance across countries. Although all processors of roasted coffee purchase green coffee at the same price in the international markets, one finds significant differences in retail prices among these countries. The study develops an Error Correction (EC) representation model to assess PTA of non-stationary models. Finally, it claims that identifying differences in price transmission asymmetry is an approach to compare market structure across countries.

Most Rwandan coffee is currently grown and processed the same way it was a decade ago.  Consequently, Rwanda’s coffee production and marketing system has not been able to keep up with  changes in the global market for high quality coffee. Given world market gluts of relatively poor quality coffee, Rwanda is now exporting a product that fetches low prices. Despite the challenges in coffee marketing and production, coffee remains one of Rwanda’s most important official sources of foreign exchange and the drop in production is of major concern to both the public and private sectors. In an effort to assist decision makers in the coffee sector better understand factors affecting farmers’ production decisions and their attitudes about coffee, the FSRP fielded a...

The coffee is one of the most important products in the economy of Minas Gerais. In some specific places it has a great importance in the local production, but in any place the economic players involved in that market have the same trouble: the share of risk taken by them. Therefore, would be really important, and useful, to calculate the risk share of each player. Than, this article showed the risk amount absorbed by the players in the coffee market of Minas Gerais, based in the prices paid in the south of that state, the greatest region producer, trough two models of Value at Risk (VaR), the Normal Model and the Historic Simulation Model. The results shows a risk absorbed about 17,28%, with 95% of sure, and 24,60% with 99% of sure, both of them in a...

Geographical Indications of Origin as a Tool of Product Differentiation: The Case of Coffee
Provedor de dados: 31
Autores: Teuber,   Ramona.
An increasing interest in geographical indications of origin (GIs) as a tool of product differentiation can be observed in the so-called specialty coffee sector. Similar to the approach for wine in France and Italy, more and more coffee-producing countries try to establish appellations systems for coffee. Whereas some countries and regions such as Colombia or Jamaica have already legally protected GIs for coffee, most coffee GIs are still informal meaning that no legal protection has been obtained so far. But the recent acceptation of the term Café de Colombia as a Protected Geographical Indication (PGI) in the EU and the Ethiopian Trademark Initiative document the increasing engagement of coffee-producing countries to achieve an appropriate legal...

In this paper, using pseudo panel data we analyze the relation between cigarette, alcohol, and coffee consumption within the rational addiction framework. Our purpose in this study is twofold. First, we want to get more insights about behavioral processes concerning cigarette, alcohol and coffee consumption. Second, we hope that our attempt to generalize rational addiction model to include three addictive goods will be useful to generate further research in the related literature. We found that cross price elasticity of cigarette with respect to alcohol price is negative, while cross price elasticity of alcohol with respect to cigarette price is positive. We believe that drinking works as a trigger for smoking especially in social settings like bars while...

Autores: Karp,   Larry S.; Perloff,   Jeffrey M.
A linear-quadratic, dynamic feedback oligopoly model that nests various market structures is used to estimate the degree of competitiveness and the adjustment paths of the two largest coffee exporters, Brazil and Colombia. Their estimated behavior is relatively competitive. This subgame perfect dynamic model is-compared to a standard static oligopoly model and the open-loop model (the dynamic generalization of the standard static model). Both classical and Bayesian tests of open-loop and feedback dynamic models are reported.

Autores: Saenz,   Mariana.
The purpose of the following paper is to explore different factors causing structural changes in the Colombian coffee sector. The Colombian economy is characterized by a revenue function (Dixit and Norman’s GDP function) with three quasi-fixed inputs and three outputs. The characterization of the economy by a unique production possibility frontier allows modeling of the whole economy. This approach will distinguish effects of changing relative prices, different rates and biases of technological change, and changes in relative factor endowments on the coffee sector, the manufacturing sector and the rest of the economy.

A spreadsheet featuring production costs for coffee in different productivity ranges is presented in this study. The survey is based on the theory of costs and the study location was the southern region of the state of Minas Gerais, where data on 48 coffee production units were gathered during the 1998/99 harvest. Taking the economical indexes resulting from research into consideration, one may infer that expenses on variable resources represent the greater portion of the final cost of coffee. The items which affected production costs the most were crop formation, in the case of unvariable costs, and the expenses on labor, especially the seasonal kind. It was also concluded that coffee culture belongs to the scale-economy kind and , as a whole, the 1998/99...

This study focused on the interrelationships among producer, auction and world prices. In so doing, it criticized previous studies and extended technique developed by Hansen (1999) to handle inferential biases occurring as a result of specification errors. The following results were found: unidirectional transmission of shocks from the world price to the auction price and then to the producer price; asymmetries in price transmissions and adjustments in the auction market; weak interrelationship between producer and world prices causing producer price to be less responsive to changes in the world prices. In general, results imply that coffee growers’ benefit little from positive changes in the world price compared with participants in the auction markets....

With coffee prices at their lowest in a century, producing countries, which are mostly developing countries, are facing the worst crisis in history. The International Coffee Organization (ICO) acknowledges that poverty and unemployment are growing so rapidly that the consequences would be dire if nothing is done to halt the decline. This study draws welfare implications for producing countries based on import demand analysis for coffee in the three largest importers – the United States, European Union, and Japan. A differential production approach is employed. Results imply that coffee-producing countries will continue to be worse off with the expansion of exports. Hence, we suggest that they attempt new marketing strategies that include consistent...

1) Export diversification has long been at the centre of Zambia’s economic diversification policies. This article focuses on the coffee sector as a potentially important source of export diversification and examines its supply response to changes in various incentives. 2) Zambian coffee exhibits asymmetric short-run supply adjustments to long-run equilibrium such that production rises significantly after prices rise while changing little after prices fall. 3) The fact that coffee in Zambia is mainly grown for export, the changes in real exchange have the most significant effect on supply in that a depreciation in the Zambian Kwacha leads to an increase in coffee supply.

Coffee consumption in China is increasing rapidly over the recent years. This study offers one of the few initial attempts to not only understand general consumption behavior associated with Chinese coffee, but to explore the viability of niche markets for coffee with the credence attribute “fair trade”. A modified payment card approach was adopted as the consumer willingness to pay elicitation method. Survey results of 564 consumers from the city of Wuhan, China suggest a positive attitude toward coffee as an alternative drink and a willingness to pay a premium for “fair trade” coffee. This study also explores and describes the potential impact of starting point bias, which has been relatively well documented in the dichotomous choice literature but has...

We review studies on the relationships between (1) conflict and food insecurity, (2) conflict and globalization, and (3) globalization and food insecurity. Next, we analyze country-level, historical contexts where export crops, such as coffee and cotton, have been implicated in triggering and perpetuating conflict. These cases suggest that it is not export cropping per se, but production and trade structures and food and...

Provedor de dados: 31
Autores: Pereira,   Vanessa da Fonseca; Campos,   Antonio Carvalho; Braga,   Marcelo Jose; Mendonca,   Talles Girardi de.
This study analyzed the Brazilian coffee exporter’s losses between the years 2002 and 2009, by emphasizing the 2007/09 crisis, which affected several sectors and generated instability and uncertainty about the future results of the economic activities. The Brazilian coffee exporting sector is fully inserted in this context, once it acts in the financial markets and it is still subject to the strong variations from the physical market. Thus, the central analysis dealt with the volatility of the exporters returns and was based on auto regressive models with conditional heteroscedaticity (ARCH) and on the Value at Risk (VAR) estimative. As a supplement, the effects from the external demand for the Brazilian coffee and from the exchange rate variation over the...

COST PASS-THROUGH IN THE U.S. COFFEE INDUSTRY
Provedor de dados: 31
Autores: Leibtag,   Ephraim S.; Nakamura,   Alice; Nakamura,   Emi; Zerom,   Dawit.
A rich data set of coffee prices and costs was used to determine to what extent changes in commodity costs affect manufacturer and retail prices. On average, a 10-cent increase in the cost of a pound of green coffee beans in a given quarter results in a 2-cent increase in manufacturer and retail prices in that quarter. If a cost change persists for several quarters, it will be incorporated into manufacturer prices approximately cent-forcent with the commodity-cost change. Given the substantial fixed costs and markups involved in coffee manufacturing, this translates into about a 3-percent change in retail prices for a 10-percent change in commodity prices. We do not find robust evidence that coffee prices respond more to increases than to decreases in costs.

Imperfeição comercial e diferenciação, por origem, no mercado internacional de cafés
Provedor de dados: 31
Autores: Viana,   Jose Jair Soares; Silva,   Orlando Monteiro da.
In this study, a world model for the international market of coffee is developed and analyzed, considering its major exporters (Brazil, Colombia, Mexico, Africa, Central America and Asia) and its major importers (United States, Germany, Japan, France, Italy, Spain, Canada, United Kingdom, Holland). That model is, then, simulated for several shocks such as the reduction of barriers that would reduce prices of coffee in all import markets, an increase in income that would increase the world demand, and variations in production of Brazil and Asia. The results evaluated in the short and long run, indicated that the main effects on the coffee prices occurs when there are changes in production, especially in Brazil. The reductions of barriers have small effects...

Are Geographical Indications a way to "decommodify" the coffee market?
Provedor de dados: 31
Autores: Galtier,   F.; Belletti,   Giovanni; Marescotti,   Andrea.
The commodity nature of green coffee is the main cause of “the coffee paradox” (decreasing prices at production level and rising prices at consumption level). So, a requirement to reach a less unfair distribution of the added value between the supply chain would be to “decommodify” the coffee market not only at the final consumer level, but also at the production level. Certifications (like Fair Trade, Organic, Rainforest Alliance, Utz Kapeh, or Birdfriend) are often presented as a way to reach this result, but according to some authors these schemes seem to be rather an extension of the standardization wave to new quality attributes (linked to social and/or environmental characteristics of the production process). Geographical indications (GIs) seems to...

Autores: Saes,   Maria Sylvia Macchione; Spers,   Eduardo Eugenio.
Differentiation through added value improvement has been explored by strategy and marketing literature. However, because of the distance between growers, final-consumers and technical features not always easily understood by the consumers, differentiation attributes adopted in agricultural production may not be perceived or valorized by the consumers. The article aims to verify whether the strategies of differentiation of rural coffee growers, through the introduction of products that value the origin or the production process have been noticed by Brazilian consumers. For that purpose, a research was conducted with 300 upper-crust consumers in coffee shops and supermarkets in the capital of the state of São Paulo in March and April 2005. The results...

Many forested areas have been converted to intensive agricultural use to satisfy food, fiber, and forage production for a growing world population. There is great interest in evaluating forest conversion to cultivated land because this conversion adversely affects several soil properties. We examined soil microbial, physical, and chemical properties in an Oxisol (Latossolo Vermelho distrófico) of southern Brazil 24 years after forest conversion to a perennial crop with coffee or annual grain crops (maize and soybeans) in conventional tillage or no-tillage. One goal was to determine which soil quality parameters seemed most sensitive to change. A second goal was to test the hypothesis that no-tillage optimized preservation of soil quality indicators in...

Autores: Melo,Vander Freitas; Orrutéa,Alessandro Góis; Motta,Antônio Carlos Vargas; Testoni,Samara Alves.
ABSTRACT Many Amazonian farmers use the slash-and-burn method rather than fertilization for crop production. The aim of the present study was to evaluate changes in the morphological, physical, and chemical properties of naturally fertile Inceptisols after conversion from native forest to different uses in southern Amazonia, Brazil. Land covered by dense native forest (NF) was split into four areas of 1.0 ha each. Three areas were slashed and burned and then cultivated for 11 years with coffee (CO), secondary forest (SF), and pasture (PA). Four soil profiles were sampled in each treatment (four uses × four replicates). The mean value distribution of each physical and chemical analysis was determined for different depths, and standard error bars were placed...

Leaf area estimation of medium size plants using optical metrology
Provedor de dados: 91
Autores: Ribeiro,Kleber M.; Braga,Roberto A.; Scalco,Myriane S.; Horgan,Graham W.
The total leaf area (TLA) estimation is an important feature of the crops and their assessment a challenge, since the direct methods of obtaining it are destructive and time consuming. Non-destructive methods have been explored to obtain the TLA by indirect approaches, in turn creating other features, as the leaf area index. The development of non-destructive technology to access the TLA of a plant has been the subject of much research, and the optical metrology is an promising approach. In this work, some indirect methods associated with optical approaches were evaluated as an alternative to obtain the TLA of the coffee plant. Commercial equipment were used, such as a camera with a fish eye lens and lux meters, associated to the sizes of the canopies were...

This study characterizes the use of risk monitoring mechanisms by coffee and soybean trading and processing companies. It also investigates the role these mechanisms play in the mitigation of certain transaction costs associated to bounded rationality, information asymmetry, and business opportunism in negotiations involving derivatives. The results presented are based on literature and original research, which consisted of interviews with 19 coffee and soybean trading and processing company agents that deal with the management and execution of derivatives trades. The interviews suggest that the interest in formal risk monitoring mechanisms depends strongly on the organizational structure of the business. In family businesses, in which the owner...

Genetic diversity of cultivated Coffea arabica inbred lines assessed by RAPD, AFLP and SSR marker systems
Provedor de dados: 63
Autores: Maluf,Mirian Perez; Silvestrini,Milene; Ruggiero,Luciana Machado de Campos; Guerreiro Filho,Oliveiro; Colombo,Carlos Augusto.
One of the greatest problems in Coffea arabica breeding is identifying precisely any inbred line, based only on botanical and agronomical descriptors, because of the reduced genetic variability of the species, close pedigree origin, which results in small phenotypic variation. Recently, molecular markers have been used for plant germplasm characterization and identification in several commercial species. This work evaluates the reliability of three marker systems: RAPD, AFLP and SSR, to characterize the genetic variability of commercially-used Coffea inbred lines developed by the Instituto Agronômico (IAC), and their potential for cultivar identification. All methods identified polymorphisms among the cultivars. The genetic diversity recognized by the...

Bayesian sequential procedure to estimate the viability of seeds Coffea arabica L. in tetrazolium test
Provedor de dados: 63
Autores: Brighenti,Carla Regina Guimarães; Cirillo,Marcelo Ângelo; Costa,André Luís Alves; Rosa,Sttela Dellyzete Veiga Franco da; Guimarães,Renato Mendes.
ABSTRACT: Tetrazolium tests use conventional sampling techniques in which a sample has a fixed size. These tests may be improved by sequential sampling, which does not work with fixed-size samples. When data obtained from an experiment are analyzed sequentially the analysis can be terminated when a particular decision has been made, and thus, there is no need to pre-establish the number of seeds to assess. Bayesian statistics can also help, if we have sufficient knowledge about coffee production in the area to construct a prior distribution. Therefore, we used the Bayesian sequential approach to estimate the percentage of viable coffee seeds submitted to tetrazolium testing, and we incorporated priors with information from other analyses of crops from...

Soil organic matter of a humic Oxisol has been characterized by analyzing litter and soil lipid composition under vegetal covers (coffee, pasture and fragment of native forest). Soil and litter samples were collected from each site at two depths (0-10 and 60-100 cm). Lipid composition was determined by gas chromatography-mass spectrometry (CG-MS). In the solvent extracts of the soil lipids, even-numbered n-alkanoic acids in the range of C16-C32 indicate a soil organic matter input from higher plant waxes. The major compound classes in both the soil and the litter included saturated n-alkanoic acids, with average values in the total spectrum of 58 and 53%, respectively Clear differences in lipid composition were found between the topsoil and subsurface....

Brachiaria decumbens is becoming one the most common weeds growing in young coffee orchards because, besides its fast growth and difficulty of control, new coffee orchards are usually established in pasture areas. In order to verify the effect of B. decumbens plant density on the early growth of coffee (Coffea arabica L. cv. Catuaí Amarelo), a competition experiment was conducted under semi-controlled humidity conditions. Soil collected in a Typic Haplustox was placed in 70 L asbestos cement boxes and one coffee seedling was planted in each box. The B. decumbens seedlings were transplanted to the boxes at the 2-4 leaf stage. Treatments consisted of 0, 4, 8, 12, 16, 20, 24, 36, 48, and 60 weeds m-2.

PRESENCE OF ASPERGILLUS AND OTHER FUNGAL SYMBIONTS IN COFFEE BEANS FROM COLOMBIA
Provedor de dados: 37
Autores: GAMBOA-GAITÁN,MIGUEL ÁNGEL.
Fungi are common inhabitants of plants and plant-derived products. Some of these fungal species are potentially dangerous to human health since they are able to produce chemical substances that alter normal physiological activity. There are no studies about natural mycoflora associated with coffee beans in Colombia, and nothing is known about the presence and abundance of toxigenic fungal species in Colombian coffee. In this study 5,000 coffee beans were studied by plating them on potato-based artificial culture medium and it was shown that potentially toxigenic fungal taxa (mostly from genera Aspergillus, Fusarium, Penicillium), are currently found in Colombian coffee beans. This is true for all steps of coffee processing, from berries in trees to toasted...

The ratio of nitrogen (N) to potassium (K) is important in the production of specialty coffees because the relative amounts of N and K can either suppress the formation or increase the concentration of compounds that are essential to the flavor and aroma of specialty coffees. The purpose of this study was to evaluate the effect of different N:K ratios (w/w) and K doses on the cup quality of coffee. The concentrations of chemical compounds essentials to achieve good flavor and aroma, the N and K contents, and the caffeine contents of coffee leaves and beans were evaluated in this study. The N:K ratio and the K dose were found to be important factors in cup quality, the best quality corresponding to an N:K ratio of 1:1.56. The best cup quality was obtained...

The chemical reactions carried out by microorganisms have been used as a tool in modern chemistry. This paper reports the production of mycophenolic acid and a new phthalide by the endophytic fungus Penicillium crustosum obtained from coffee seeds. The fungus was cultivated in a liquid medium for a period of seven days and after that the culture medium was divided into four treatments: A, B, C and D, to which different organic substances were added. Treatment A was maintained as the control to evaluate the occurrence of biotransformation. Organic acids were added to the culture media of treatments B (ferulic and quinic acids) and C [cinnamic and 3,4-(methylenedioxy) cinnamic acids], and caffeine was added in the treatment D. All these organic compounds...

A new concept for insect damage evaluation based on plant physiological variables
Provedor de dados: 42
Autores: Neves,Ademir D.; Oliveira,Ricardo F.; Parra,José R.P.
The objective of this study was to determine the damage levels caused by Orthezia praelonga Douglas, 1891 and Leucoptera coffeella (Guérin-Mèneville 1842), on rangpur lime and Obatã coffee leaves, respectively. Measurements were based on a new concept for the evaluation of the following plant physiological parameters: photosynthesis, stomatal conductance, leaf temperature and transpiration, and internal concentration of CO2 (by infrared analyzer). A negative correlation between infestation level and photosynthesis was found, where the negative inflexion point of the curve was considered as a reference for damage levels. The control level for O. praelonga is below the 7-13% limit for damaged leaf area (40 to 70 scales per leaf), while for L. coffeella it is...

Predators impairing the natural biological control of parasitoids
Provedor de dados: 44
Autores: Reis Jr,Ronaldo; Souza,Og De; Vilela,Evaldo F.
A well known case of ineffective natural biological control: the puzzling coexistence of the coffee leaf miner, Leucoptera coffeellum (Guérin-Mèneville), and its natural enemies was analyzed. Despite being a suitable prey to eight parasitoid species and three wasp species, all occurring simultaneously, the coffee leaf miner too often presents populations far above the damaging level for the coffee plantation. It is demonstrated that predatory wasps and parasitoids interact negatively, possibly because predatory wasps kill parasitized miner's larvae. In doing so, predatory wasps indirectly kill parasitoids, thereby impairing the efficacy of the natural biological control. It is warned that biological control programs should be based on knowledge of food web...

Autores: Gutierrez,Andrew P.; Villacorta,Amador; Cure,Jose R.; Ellis,C. Ken.
An age-mass structured multi-year tritrophic simulation model of the coffee (Coffea arabica var. mundo novo) - coffee berry borer [Hypothenemus hampei (Ferrari)], borer - three parasitoid system was developed. Three years of extensive plant drymatter data and one year of field data on borer dynamics were collected at Londrina, PR, Brazil. The allometric relationships and parameter for plant drymatter allocation were estimated from the field data, but the parameters for borer and its three parasitoids were summarized from the literature. Initial levels of soil factors (e.g., nitrogen and water) and observed weather data were used to drive the model. The model is largely independent of the field data, yet it simulated the dynamics of plant branching,...

Effect of 6-BA on nodal explant bud sproutings of Coffea arabica cv. Mundo Novo
Provedor de dados: 53
Autores: Ramos,Luis Carlos da Silva; Almeida,Julieta Andrea Silva de.
Coffee plants can be micropropagated by nodal bud sprouting using the 6-benzylaminopurine (6-BA) hormone. However, literature reports the use of a wide range of 6-BA, from 0.5 to 88.8 µM L-1. So, this study was performed to narrow that range. Nodal explants of Coffea arabica cv Mundo Novo obtained from in vitro plantlets were inoculated on gelled-MS medium supplemented with different concentrations of 6-BA. Two assays were carried out: in the first one, 6-BA was used at concentrations of 0, 5, 25, 50, and 100 µM L-1, being evaluated at 43 and 123 days. In the second experiment, dosis of 10, 20 and 30 µM L-1, have evaluated at 65 and 100 days. Treatments with 6-BA induced multiple sprouting from the nodal explants, which were best characterized around 100...

Autores: RAMOS,LUIS CARLOS DA SILVA; CARVALHO,ALCIDES.
Roots and shoots from seedlings of 29 coffee genotypes were studied to better characterize the entries from the Coffea germplasm bank of the Instituto Agronômico (IAC), Campinas, State of São Paulo, Brasil. The varieties were seeded in a randomized complete block design with 6 replications and 10 plants per plot. The characters evaluated were: plant (PL), shoot (SL) and root (RL) length; total plant (PDM), shoot (SDM), root (RDM) and lateral root (LRDM) dry matter. A lateral root index (LRI) and shoot root dry matter (SRDM = SDM/RDM) and length ratios; (SRL = SL/RL) were calculated. The dwarf varieties (Catuaí, Icatu-caturra, Vila Sarchi, San Ramon, Vila Lobos, São Bernardo) presented higher LRDM and lower SDM than the normal size varieties such as Mundo...

Effect of leaf Water potential on cold tolerance of Coffea arabica L.
Provedor de dados: 52
Autores: Caramori,Lázara Pereira Campos; Caramori,Paulo Henrique; Manetti Filho,João.
Young coffee plants from cultivar Mundo Novo of Coffea arabica were grown without irrigation for 32 consecutive days, to evaluate the effect of leaf water potential on damage caused by low temperatures, under controlled conditions. A wide range of leaf water potentials were evaluated, from - 0.45MPa (wet soil) at the beginning of the experimental period, to - 4.8MPa (severe leaf wilting) at the end. Results showed that under moderate water stress, there was a higher frequency of undamaged plants and lower frequency of severely damaged plants. These results help explain part of the regional variability observed after a frost and stress the importance of new studies associating cold and drought tolerance in coffee.

Modifications on leaf anatomy in Coffea arabica shaded with pigeonpea (Cajanus cajan), compared to cultivation under full sun, were assessed. The leaves fully exposed to sunlight presented thicker cuticles and cellular walls, narrower epidermis cells, palisade parenchyma with longer cells, thicker lacunar parenchyma, fewer intercellular spaces and a larger stomata number. Leaves under dense shade presented a narrower cuticle and cellular wall; a mesophyll with smaller volume, but with larger intercellular spaces; and epidermis with thicker cells and a smaller stomata amount, surrounded by subsidiary cells of smaller dimensions. Plants grown under full sunlight presented higher values of net photosynthesis. The results evidenced that the species C. arabica...

Caffeine formation by suspension cultures of Coffea dewevrei
Provedor de dados: 52
Autores: Sartor,Rosana Mary; Mazzafera,Paulo.
The low caffeine content in leaves of C. dewevrei (~ 0.5 mg/g) is due to a low biosynthesis associated with a fast degradation. On the other hand, high biosynthesis and low degradation confer a higher content (~ 8 mg/g) in leaves of C. arabica. In this work it was observed that cell cultures of C. dewevrei recovered the ability to synthesize caffeine almost in similar levels of C. arabica cultures. Tracer experiments with labelled carbon dioxide showed a significant accumulation of radioactivity in caffeine and metabolites, indicating an active biosynthesis. When the cultures were fed with labelled caffeine most of the radioactivity was recovered in caffeine, indicating that although active, degradation was not so efficient as in leaves, and therefore,...

Abstract The influence of silver nitrate (AgNO3), benzyladenine (BAP), and indole-3-acetic acid (IAA) on low frequency somatic embryogenesis (LFSE) induction in Caturra and Catuaí arabica coffee was evaluated. For the Caturra cultivar, the production of somatic embryos was significantly increased by adding AgNO3 to the semisolid culture medium. The highest average number of somatic embryos for this cultivar was obtained using 6.6 μM BAP, 2.85 μM IAA, and 40 μM AgNO3. In contrast, for the Catuaí cultivar, the highest average number of somatic embryos was obtained using semisolid medium supplemented with 8.8 μM BAP, and 2.85 μM IAA. Using these protocols, somatic embryos were directly induced using leaf sections of in vitro plants of both coffee cultivars...

Ethylene production and acc oxidase gene expression during fruit ripening of Coffea arabica L.
Provedor de dados: 61
Autores: Pereira,Luiz Filipe Protasio; Galvão,Rafaelo M.; Kobayashi,Adilson K.; Cação,Sandra Maria B.; Vieira,Luiz Gonzaga Esteves.
The phytohormone ethylene is involved in several physiological and developmental processes in higher plants, including ripening of fruits, abscission of organs and tissues, senescence, wound response as well as in other abiotic stresses. The enzyme 1-aminocyclopropane-1-carboxylate oxidase (ACO) catalyzes the last step of ethylene biosynthesis. The production of ethylene and the expression of a Coffea arabica ACO gene during the last stages of fruit maturation were investigated. A rapid increase of ethylene production at the green-yellow stage of fruit ripening, after the end of endosperm formation, and a decrease of ethylene production at the cherry stage indicates a climacteric phase during ripening. An ACC oxidase (Ca-ACO) from coffee fruit cDNA was...

The distribution of in vivo nitrate reductase (EC 1.6.6.1) activity (NRA) between leaves and roots was studied in young coffee plants (Coffea arabica L.) grown in pots with watered sand in a glasshouse and irrigated with nutrient solution. The influence of irradiance regimes on the partitioning of NRA, and its relation with CO2 assimilation, was also evaluated in plants grown under approximately 20, 50 and 100% of full sunlight. Time-course of nitrate accumulation in nitrogen-starved plants showed a similar pattern in leaves and roots after supplying 15 mmol L-1 nitrate, indicating efficient ability of the roots to export nitrate to the shoot. At the same time, NRA was rapidly induced in both tissues. In shoots, NRA partitioning was synchronized among the...

Three degrees of red mite infestation (Oligonychus ilicis McGregor) (Acari: Tetranychidae) were evaluated with regard to leaf anatomy, photosynthetic gas exchange and leaf ethylene production, in a commercial crop of approximately 12-year-old trees of Coffea arabica 'Catuaí Vermelho'. As a complementary study, foliar anatomy was also evaluated in a recuperated crop of C. arabica 'Mundo Novo' that had presented a high degree of red mite infestation during the dry period of the prior growing season. The red mite-infested leaves were bronze-coloured, with intensity proportional to the degree of internal damage. On feeding, the red mite introduces its stylet in the adaxial epidermis and, as a result, chloroplasts are destroyed in the feeding area. The number...

The objective of this work was to evaluate the agronomic traits of coffee tree progenies. The experiment was set in Ouro Verde Farm, located at Campos Altos County, MG. Twenty three coffee progenies and seven control cultivars were used. These progenies are from the fourth generation of crossing between Timor Hybrid and Catuaí. The experiment was set in a randomized block design with four replicates, a total of 120 plots with 8 plants per plot. The yield of processed coffee sacks ha-1 was evaluated in eight crop years from the 2003 to the 2011 harvests. The percentage of fruits at the cherry stage, floating fruits, coffee classification (sieve above 17), income and plant vigor were evaluated in the 2010 and in the 2011 harvests. It was concluded that the...

ABSTRACT The benefits of mycorrhization occur with the growth of hyphae in colonized roots by promoting an increase of the contact surface which improves the initial growth due to a better absorption of water and nutrients. The objective was to evaluate the effect of arbuscular mycorrhizal fungus Rhizophagus clarus inoculation over the initial development and nutritional response of six genotypes of Coffea arabica L. Six genotypes of Coffea arabica L. were used (MGS Aranas, H29-1-8-5, Red Catuai IAC 144, IPR 100, Catigua MG2, Paraíso H 419-1) and with arbuscular mycorrhizal fungus - AMF: Rhizophagus clarus and without the application of the fungus. For the production of coffee seedlings, seeds were placed to germinate in plastic trays with sterile sand....
