O consumo e o mercado de cafés especiais, como orgânicos, gourmets e socialmente justos, cresce no mundo todo oferecendo preços atraentes para o produtor, enquanto o mercado de cafés commodity encontra grande oferta e preços muito baixos. A produção orgânica revela-se como alternativa ambiental, social e econômica, pois não contamina o meio ambiente e nem as pessoas direta e indiretamente envolvidas, além de agregar mais valor ao produto final. Apesar de o Brasil ser o maior produtor mundial de café, com aproximadamente 45 milhões de sacas em 2002, a produção de café orgânico foi aproximadamente de 70 mil sacas, de acordo com a ACOB (Associação de Cafeicultura Orgânica do Brasil). O México é o maior produtor mundial de café orgânico, com aproximadamente 500 mil sacas em 2002, sendo a maioria proveniente de sistemas sombreados de café. A cafeicultura nacional caracteriza-se por extensas áreas de monocultivo a pleno sol, desconsiderando o fato do café ser uma espécie originária de florestas caducifólias da Etiópia. A produção de café orgânico brasileira também é, em sua maioria, a pleno sol, com pouca biodiversidade e grande input ao sistema. Países produtores de café orgânico em sistemas sombreados e consumidores criticam a ausência de biodiversidade do sistema brasileiro. Portanto...

Produzido em mais de 60 países e movimentando anualmente US$ 70 bilhões, o café é a segunda commodity mais comercializada no mundo, atrás somente do petróleo. É também, depois da água, a bebida mais popular, com consumo mundial anual superior a 400 bilhões de xícaras. O mercado internacional de cafés especiais, como orgânicos, sombreados, gourmets e socialmente justos cresce 12% ao ano, gerando oportunidades para produtores de café do mundo todo. Apesar de o Brasil ser o maior produtor e exportador mundial de café, com 38 milhões de sacas de 60 kg produzidas e 26 milhões de sacas exportadas na média dos anos de 2003 a 2007, sua produção de café sombreado e orgânico é reduzida. O cultivo sombreado predomina na maioria dos países enquanto o Brasil é caracterizado por áreas de monocultivo a pleno sol. Assim, grande parte da produção brasileira de café é originada de sistemas com pouca biodiversidade, contrapondo-se à crescente preocupação mundial com o meio ambiente e a qualidade de vida. Sistemas sombreados de café aumentam a biodiversidade nas propriedades e contribuem para a mitigação do aquecimento global, além de apresentarem vantagens técnicas potenciais como menor pressão de pragas e doenças e melhoria das condições hídricas e térmicas locais. A discussão sobre cultivo sombreado versus a pleno sol já se desenvolve há mais de um século...

Mudanças na bebida e na cor dos grãos durante o armazenamento do café cru levam à perda do valor no mercado devido, provavelmente, a processos oxidativos nos lipídios. Durante a oxidação dos lipídios há formação de compostos muito reativos, os quais podem reagir com proteínas, ácidos clorogênicos e outros compostos presentes no grão cru. O objetivo do presente trabalho foi avaliar em café natural (CN) e café cereja descascado (CD) da cultivar IPR 98 as alterações nos lipídios, proteínas, ácido 5-cafeoilquínico, viabilidade da semente e na estrutura celular do grão, além das mudanças sensoriais na bebida e na cor do grão, verificando se a perda da qualidade sensorial durante a estocagem por 15 meses está relacionada com processos oxidativos. As modificações nos lipídios foram avaliadas pelo acompanhamento do processo oxidativo mediante análises de substâncias reativas com ácido tiobarbitúrico (TBARS) e no teor de ácidos graxos livres. A fração de ácidos graxos livres foi analisada por cromatografia gasosa após a extração com éter metil-t-butílico e fracionamento por cromatografia de permeação em gel. A oxidação de proteínas foi medida pelo método espectrofotométrico empregando dinitrofenilidrazina para a formação de osazonas. O teor do ácido 5-cafeolquínico foi medido utilizando cromatografia líquida de alta eficiência com detector de arranjo de diodos. A avaliação da viabilidade da semente foi realizada mediante imersão em sal de tetrazólio...

No presente estudo foi avaliado o perfil qualitativo e quantitativo de compostos bioativos por HPLC-DAD-MSn e a capacidade antioxidante de bebidas de café e de sementes de café cru de diferentes genótipos frente às principais espécies reativas de oxigênio (ERO) e de nitrogênio (ERN) de relevância biológica. As bebidas de café foram preparadas com café torrado e moído (7 regulares e 3 descafeinados) e com café solúvel (2 regulares e 2 descafeinados), ambos comerciais. Nas bebidas de café foram identificados e quantificados 16 ácidos clorogênicos (ácido 5-cafeoilquínico foi o majoritário), 4 lactonas de ácidos clorogênicos, 2 conjugados de cinamoil-aminoácido, 2 ácidos cinâmicos livres, trigonelina, ácido nicotínico, 5-hidroximetilfurfural, teobromina, teofilina e cafeína. Este é o primeiro trabalho que relata a presença de isômeros do ácido cafeoilferuloilquínico e conjugados de cinamoil aminoácido em bebidas de café solúvel. Em geral, o perfil qualitativo de compostos bioativos foi similar entre as bebidas de café. Por outro lado, foram encontradas diferenças quantitativas destes compostos entre as bebidas de café torrado e moído e de café solúvel, e entre as bebidas de café regular e descafeinado. Estas diferenças provavelmente são devido às diferentes espécies e variedades de café usadas nos blends...

Viability of seeds stored in genebanks must be maintained for several years or even centuries. Because of the difficulties in storing the seeds, coffee germplasm is maintained in field collections, presenting significant problems, such as land and labor costs and susceptibility to environmental hazards and pathogens. Storage of Coffea species in ex situ genebanks may help to preserve the threatened diversity of this important genus. Since 1976 the International Plant Genetic Resources Institute has considered coffee as a high priority for genetic conservation. For non-orthodox seed species, cryopreservation is the only technique available for long-term germplasm conservation. The genebank of Embrapa Genetic Resources and Biotechnology, in Brazil has now established a program to cryopreserve genetic resources of Coffea. The protocol was first determined for C. arabica and C. racemosa. Seeds were first dried to 0.20 g/g (in equilibrium with 78-80% RH). Sufficiently rapid cooling and warming was achieved in hermetically-sealed foil-laminate bags containing 10-11 g (or 50 seeds) by plunging bags directly into liquid nitrogen ? LN containers and placing bags removed from LN directly into a 40 °C bath. Successfully cryopreserved C. arabica and C. racemosa seeds showed minimal viability loss after two-year storage in liquid nitrogen. The same protocol is being adapted to other species of Coffea.; 2007

The most important lipids in coffee, the diterpenes khaweol and cafestol, are originated from the isoprenoid pathway. Despite their diversity in functions and structures, all isoprenoids derive from the common-five carbon building unit isopentenyl diphosphate (IPP) and its isomer dimethylallyl diphosphate (DMAPP). In higher plants, there are two independent pathways located in the cytosol (mevalonic acid or MVA pathway) and in the plastids (methylerythritol phosphate ? MEP ? or non mevalonic pathway). Throughout the data mining of the Brazilian Coffee Genome Project we studied the genes that code for the enzymes 3-hydroxy-3-methyglutaryl-CoA reductase (HMGR) and mevalonate diphosphate decarboxylase (MPDC) for the MVA pathway and 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR) and isopentenyl diphosphate/dimethylallyl diphosphate synthase (IDS) for the MEP pathway.; 2007

WRKY family proteins are transcription factors involved in the regulation of development and plant defense response pathways. The Arabidopsis thaliana WRKY superfamily is made of 75 members. Common to these proteins is a DNA-binding region of approximately 60 amino acids in length which comprises the absolutely conserved sequence motif WRKY adjacent to a novel zinc-finger motif. A comparative phylogenetic analysis of the WRKY gene family in coffee and A. thaliana was conducted to assess the diversity of this family in coffee and to identify homologous coffee genes with putative function in defense responses to pathogens. Bioinformatic analysis of around 200 000 coffee Expressed Sequence Tags (ESTs) identified 313 ESTs with BLAST homologies to WRKY proteins. Almost 30 different putative WRKY genes were obtained, but only 25 unigenes encoding a protein with a WRKY domain were identified. Alignement of the WRKY domain sequences of the 25 coffee unigenes together with those of 72 A. thaliana WRKY genes showed a high conservation of the WRKY motif and the zinc-finger motif in the coffee WRKY domain. The 25 coffee WRKY members were distributed among the 3 main A. thaliana WRKY subgroups, with group I members displaying two WRKY domains, as expected. Conservation of the intron position within the WRKY domain sequence was evidenced when cloning the genomic sequence of one WRKY coffee gene (CaWRKY1). Clustering of the coffee WRKY genes based on the EST distribution in cDNA libraries made from tissues under several physiological conditions allowed to identify genes associated with development or with plant defense responses. To assess the involvement of WRKY genes in the coffee defense response pathways...

The most acknowledged method for coffee leaf-rust resistance evaluation uses leaf disks inoculated with Hemileia vastatrix and kept in moisture chambers. Besides an efficient control of inoculation conditions, this technique allows a simultaneous evaluation of innumerous plants, with diverse fungal race/coffee genotype combinations, and using low uredospore quantities. The objective of this study was to evaluate the suitability of this technique for the functional gene analysis of coffee responses to leaf-rust infection. A comparison of gene expression in the presence or absence of the pathogen was performed on intact leaves and on leaf disks. To avoid non-specific gene expression due to leaf injury, the leaf disks were prepared 24h and 48h before inoculation and kept moist. Coffea arabica plant samples of the resistant Obatã and the susceptible Ouro Verde cultivars were challenged with H. vastatrix race II and were collected 24 h after inoculation. Semi-quantitative reverse transcription (RT)-PCR and real time quantitative PCR were used to evaluate expression of several coffee genes. Genes known to be constitutively expressed such as the Glyceraldehyde 3-phosphate deshydrogenase gene or the Ubiquitine gene were used, as well as genes involved in disease resistance responses. Results demonstrated that overall there are differences in the gene expression patterns observed in leaves and disks...

Precision agriculture appears as an important tool in the management of coffee farms where the knowledge of some soil fertility characteristics associated with the coffee production could help in specific application of fertilizers with positive environmental and economic results. So the aim of this article was to use precision agriculture and geoestatistics to evaluate the availability of phosphorus, potassium and yield of the coffee plant by evaluating the semivariogram and kriging maps and show that these tools are important for coffee management. This study was conducted on the Brejão farm in Três Pontas, Minas Gerais state, Brazil. As a data base we used soil chemical property data obtained by sampling in a georreferenced location using a quadricycle with a sampler and a GPS, and the yield data was obtained from manual harvest on the georreferenced location. The analysis of these data by using statistics and geostatistics tools allowed to characterize the spatial variability of the phosphorus, potassium, and the coffee yield, and allowed to analyze the relation among these variables. It was possible to observe that spatial dependence exists so it is possible to create maps of spatial distribution of the variables.

Through this study, we sought to evaluate the economic efficiency of the allocation of productive resources of coffee in the south of Minas Gerais. The cities surveyed are among the largest producers in the south of this state: Alfenas, Guaxupé, São Sebastião do Paraíso, Varginha and Tres Pontas, totaling 46 coffee plantations. This study is based on the principles of the theory of production and cost, using the stochastic production frontier model to measure and estimate the production function. The technical coefficients refer to the agricultural years 2006/2007, 2007/2008 and 2008/2009, which were adjusted for the 2008/2009 harvest. On average, farmers have an economic efficiency of 70.3%. Coffee producers were considered cost efficient when the measure of economic efficiency (EE) was equal to or greater than 90.0%. The percentage of farmers who have achieved this minimum score of efficiency stands at 28.2%. The results indicate inefficient use of productive resources in most cases, both technically and economically

This study was conducted with the aim of evaluating the influence of mechanization on economic and financial feasibility of establishing coffee plantations in the southern region of the State of Minas Gerais. Thus, techniques or project analysis indicators were used to verify the economic and financial feasibility of investing in coffee activity. The main results conclude that, the use of mechanization in the coffee harvest, when possible, has a significant impact on the composition of costs, which directly influences the performance of the coffee enterprise in the southern region of Minas Gerais. Finally, we note that the price of coffee has an influence on the economic viability of coffee investment which is essential to the profitability. Thus, the rural entrepreneur must use a management style that emphasizes planning and cost management and seeks to optimize the productive resources used in coffee plantations, while also using market mechanisms to minimize the risk of coffee price variability in the future market.

Current coffee prices are at record lows and below the cost of production for many producers in Central America. Moreover, the coffee crisis is structural, and changes in supply and demand do not indicate a quick recovery of prices. So, coffee producers in Central America are facing new challenges-as are coffee laborers, coffee exporters, and others linked to the coffee sector. Coffee plays a major economic role in Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. The coffee crisis is actually part of a broader rural crisis caused by weather shocks (such as Hurricane Mitch and droughts), low international agricultural commodity prices, and the global recession. These challenges call for new strategies for Central American countries aimed at broad-based sustainable development of their rural economies. The authors deal with the impact of the coffee crisis and strategies to deal with it. They include an analysis of the international coffee situation and country-specific analyses. The authors explore options and constraints for increased competitiveness and diversification...

A reform in Burundi's coffee sector is currently under way. Even though the reform was launched by the government of Burundi in 1992, it was only in 2008 that implementation fully started. The purpose of the reform is to restructure the coffee sector, focusing on the following processes: privatization of the industrial units (especially washing and hulling units), liberalization of government control among the production and export agencies, and reform of the state coffee institutions. To improve the reform process, a Rapid Strategic Environmental Assessment (R-SEA) was recommended. The goal of this RSEA is to analyze the environmental and socioeconomic aspects along the entire coffee value chain to provide strategic direction for the sustainability of coffee production, processing, and commercialization. This report is divided into six sections: (i) introduction; (ii) a description of Burundi's coffee sector; (iii) a brief explanation of the reform in the coffee sector; (iv) a description of the environ environmental and socioeconomic issues and gaps in the coffee sector...

Colombia is the world's third-largest producer of coffee and by far the largest single producer of washed arabica coffee. This introduction outlines the global situation in brief and sets the context with a synopsis of Colombia's coffee history and its unique coffee culture. Chapters 2 and 3 assess the impact of the current coffee situation in both economic and social terms. Chapters 4 and 5 address the current situation and the relevant issues in its production and post-harvest processes. Chapters 6 assesses the marketing chain from the grower to the exporter and considers some of the competitive options that are available. It also considers Colombia's domestic and international promotions. Chapter 7 takes a look at the relevant institutions at the local, regional, and national levels; it describes their roles and evolution and discusses issues relevant to their future. Chapters 8 and 9 review the situation of credit and the risk management options that are currently available. The policies currently selected by the government to resolve this crisis are considered in chapter 10 and compared to the lessons learned in other countries. The current production systems and their regional differences are considered in chapter 11 and some conclusions drawn about the profitability of diverse production systems in different regions. Chapter 12 discusses some of the options for the sector to capture more value for its products. The last chapter reviews some of the rationale and the required parameters for any successful diversification and reflects on the inherent challenges that a diversification efforts would present.

After experiencing a boom during the mid-1990s, the performance of Uganda's coffee industry has been disappointing. Most existing analyses see the sector's problems as quality deterioration, poor marketing position in the global market, weak regulatory framework, and poor infrastructure. Recommendations range from setting up a coffee auction to increasing the share of specialty coffees. This paper concludes that such advice has been largely inconsistent with the stylized facts of the Ugandan coffee industry. It argues that the coffee wilt disease and the effectiveness of the coffee replanting program are the two key issues on which policymakers and the donor community should focus their activities and allocate their resources.
