Effects of fruiting on the growth of Arabica coffee trees as related to carbohydrate and nitrogen status and to nitrate reductase activity
(Sociedade Brasileira de Fisiologia Vegetal, 2001) AMARAL, JOSÉ A.T.; MATTA, FÁBIO M. DA; RENA, ALEMAR B.
Active vegetative and reproductive growth in field-grown trees of Coffea arabica L. in Viçosa (20º45’S, 650 m altitude), south-eastern Brazil, occur concurrently. The overall patterns of branch growth and leaf area gain were to a certain extent altered by fruit removal, with growth rates being remarkably greater in de-fruited trees. The content of N-NO3 was not affected by fruiting, whilst that of amino-N was greater in de-fruited than fruiting trees most of the time, but the differences were not large enough to have significantly contributed to the increased growth rates in de-fruited trees. Leaf nitrate reductase activity was greater in plants bearing fruit than in non-bearing ones most of the time; activity was roughly inversely associated with growth. Although the roots contained much more nitrate than the leaves, the root nitrate reductase activity was much lower and not affected by fruiting. Much of the restrictive effects of fruiting on vegetative growth appeared to be associated to starch exhaustion, in addition to the outstanding effect of supra-optimum temperatures per se.
Seed storage proteins in coffee
(Sociedade Brasileira de Fisiologia Vegetal, 2001) BAÚ, SANDRA M. T.; MAZZAFERA, PAULO; SANTORO, LUIZ G.
It has been reported that Coffea arabica seeds contain as the main reserve protein, a legumin-like protein, constituted of two subunits, alpha and beta, of approximately 35 and 20 kDa. In this work the seed proteins of several coffee species and varieties were investigated by SDS-PAGE and gel filtration. No differences were observed in the electrophoretic profiles among varieties of C. arabica, however, marked differences were observed among species, or even among individuals of some species. In general, the molecular weight of the subunits alpha and beta accounted for a monomer of 48 to 62 kDa. However, native molecular weight obtained by gel filtration showed that for most of the species there is association of 6 of such proteins, in a hexamer. The most marked difference was observed for C. canephora and C. racemosa. The former clearly showing isoforms of the subunits, and the later showing absence of the beta subunit. The influence of proteases in this observations is discussed.
Atrativo para as abelhas Apis mellifera e polinização em café (Coffea arabica L.)
(Faculdade de Medicina Veterinária e Zootecnia / Universidade de São Paulo, 2004-04-29) Malerbo-Souza, Darclet Teresinha; Nogueira-Couto, Regina Helena; Couto, Leoman Almeida; Souza, Julio César de
O presente experimento foi conduzido em Jaboticabal, SP, e teve como objetivos estudar uma cultura de café (Coffea arabica L., var. Mundo Novo), quanto à biologia floral, a freqüência e comportamento dos insetos na flor, testar o produto Bee-HereR (Hoescht Shering Agrevo do Brasil Ltda) quanto a sua atratividade para as abelhas Apis mellifera e verificar a produção de frutos com e sem a visita dos insetos. Para isso, foram verificados o tempo do desenvolvimento e quantidade de açúcar solúvel do néctar das flores; freqüência das visitações dos insetos, no decorrer do dia, por meio de contagem do número de insetos visitando as flores, a cada 60 minutos, das 8 às 17 horas, 10 minutos em cada horário; tempo (em segundos) e tipo de coleta (néctar e/ou pólen) dos insetos mais freqüentes; perda de botões florais; porcentagem de flores que se transformaram em frutos; tempo de formação e contagem dos grãos de café, observando-se a porcentagem de frutificação em flores visitadas ou não pelos insetos. Também foram realizados testes por pulverização utilizando-se o produto Bee-HereR , diluído em xarope e em água, em diferentes horários. A flor durou, em média, cerca de 3 dias desde sua abertura até o murchamento. A quantidade de açúcares do néctar apresentou diferença significativa entre os horários, sendo maior às 8 horas (em média, 102,18 ± 8,75 mg de carboidratos totais por flor). A abelha A. mellifera foi o inseto mais freqüente nas flores de café, coletando, principalmente, néctar no decorrer do dia. A perda de botões florais causada pelas chuvas foi, em média, 26,50 ± 11,70%. O tempo para a formação do fruto foi 6 meses e o número de frutos decorrentes do tratamento descoberto foi maior (38,79% e 168,38%, em 1993 e 1994, respectivamente) que do tratamento coberto. Apesar da eficiência do produto Bee-HereR ser afetada pelas condições climáticas, ele pode ser usado para atrair as abelhas A. mellifera na cultura.
Avaliação do efeito da cafeína no teste vestibular
(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-07-26) Felipe, Lilian; Simões, Lilia Correia; Gonçalves, Denise Utsch; Mancini, Patrícia Cotta
Há controvérsias sobre a interferência da cafeína no teste vestibular. O café é a fonte mais rica em cafeína. Enquanto em alguns serviços os pacientes são orientados a suspender a ingestão de café 24 a 48 horas antes da realização do teste, outros não consideram necessária a suspensão da ingestão dessa bebida. OBJETIVO: Avaliar o efeito da cafeína no resultado do teste vestibular. FORMA DE ESTUDO: clínico com coorte transversal. MATERIAL E MÉTODO: Estudo comparativo, transversal, pareado. O teste vestibular foi realizado em duplicidade, com intervalo máximo de cinco dias entre um e outro exame. No primeiro teste, os pacientes foram orientados a não ingerir café 24 horas antes do exame; no segundo teste, os pacientes foram orientados a beber café como de costume. Todos os participantes tinham indicação clínica de se submeter ao teste vestibular e tinham o hábito de tomar café. RESULTADOS: Participaram do estudo 19 mulheres com idade média de 49,5 anos. O consumo médio de café foi de três xícaras por dia. As queixas de ansiedade e cefaléia foram associadas ao teste realizado com suspensão do café. Não houve diferença estatisticamente significante nos resultados dos exames realizados com e sem ingestão de café. CONCLUSÃO: A ingestão moderada de café não interferiu no resultado do teste vestibular. Considerando ser recomendável que o paciente esteja tranqüilo ao se submeter ao teste vestibular e que a meia-vida da cafeína é de apenas seis horas, sugerimos que a orientação para a suspensão súbita e completa da ingestão moderada de café antes do teste vestibular para os indivíduos habituados à ingestão diária seja reavaliada.
Partitioning of nitrate reductase activity in Coffea arabica L. and its relation to carbon assimilation under different irradiance regimes
(Brazilian Journal of Plant Physiology, 2007-03-26) Carelli, Maria Luiza C.; Fahl, Joel I.
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 various leaf pairs. The initial increase in NRA, as each leaf pair emerged, coincided with the optimum NRA values of the next older leaf pair. However, the average shoot NRA remained relatively constant for each sampling date. During the first 23 weeks of vegetative growth, the mean NRA was 32% higher in leaves than in roots. The irradiance regimes influenced the partitioning of NRA between leaves and roots. The NRA leaf /root ratio was 0.72, 1.21 and 1.05, respectively, for plants grown under 20%, 50% and 100% of full sunlight. Leaf NRA was positively correlated with CO2 assimilation, in response to irradiance regimes. Under favorable CO2 assimilation conditions, higher NRA was observed in leaves than in roots, and the contrary trend occurred under limiting CO2 assimilation conditions. Under moderate irradiance regime the leaves were the main site of nitrate reduction, contributing with 70% of the whole plant nitrate assimilation.
Alterations in leaf anatomy and physiology caused by the red mite (Oligonychus ilicis) in plants of Coffea arabica
(Brazilian Journal of Plant Physiology, 2007-06-15) Fahl, Joel I.; Queiroz-Voltan, Rachel B.; Carelli, Maria Luiza C.; Schiavinato, Marlene A.; Prado, Ana K. S.; Souza, Júlio C.
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 of chlorophyll-free cells in the palisade parenchyma was proportional to the intensity of attack by red mites. The cells of the spongy parenchyma, localized below the feeding areas of the mites, did not show any alterations, having intact chloroplasts, with the exception of some leaves that suffered from intense attack. Net photosynthesis rate declined, but only in leaves under intense red mite attack, due to destruction of chloroplasts in the attacked cells. Nevertheless, transpiration and stomatal conductance were unaffected by red mite. The concentrations of ethylene produced by the leaves were similar regardless of three levels of attack, suggesting that red mite infestation does not lead to leaf abscission. In addition, anatomical studies of 'Mundo Novo' leaves of plants that visually recovered from red mite attack showed that, even with scars present, they continued attached on the plant.
Ecophysiology of coffee growth and production
(Brazilian Journal of Plant Physiology, 2007-12) DaMatta, Fábio M.; Ronchi, Cláudio P.; Maestri, Moacyr; Barros, Raimundo S.
After oil, coffee is the most valuable traded commodity worldwide. In this review we highlighted some aspects of coffee growth and development in addition to focusing our attention on recent advances on the (eco)physiology of production in both Coffea arabica and C. canephora, which together account for 99% of the world coffee bean production. This review is organized into sections dealing with (i) climatic factors and environmental requirements, (ii) root and shoot growth, (iii) blossoming synchronisation, fruiting and cup quality, (iv) competition between vegetative and reproductive growth and branch die-back, (v) photosynthesis and crop yield, (vi) physiological components of crop yield, (vii) shading and agroforestry systems, and (viii) high-density plantings.
Autonomy and network modulation of photosynthesis and water relations of Coffea arabica in the field
(Brazilian Journal of Plant Physiology, 2008-08-07) Camargo-Bortolin, Lívia H.G. de; Prado, Carlos H.B. A.; Souza, Gustavo M.; Novaes, Paula
The degree of connection between leaf gas exchange and leaf water potential, and the autonomy of these variables in relation to meteorological conditions were determined in three cultivars of Coffea arabica during clear and cloudy days. High values of vapor pressure deficit, air temperature and photosynthetic photon flux density resulted in low leaf autonomy during a clear day, irrespective the degree of connection among leaf physiological variables. Tight synchronization between physiological and meteorological variables was considered one important cause of net photosynthesis (P N) decreasing during a clear day. In contrast, diurnal P N was around three times higher on a cloudy day, when all cultivars presented high autonomy. Principal component analyses corroborated autonomy results revealing unambiguous opposition between leaf physiological and meteorological vectors, besides less leaf physiological variability throughout the clear day. Despite these general responses during clear and cloudy days, there were significant differences among studied cultivars. Leaf autonomy was an important reference to evaluate C. arabica under environmental stress and should be taken into account when selecting cultivars under field conditions.
Incidence and distribution of filamentous fungi during fermentation, drying and storage of coffee (Coffea arabica L.) beans
(Sociedade Brasileira de Microbiologia, 2008-10-02) Silva, Cristina Ferreira; Batista, Luis Roberto; Schwan, Rosane Freitas
The objective of this work was to isolate and characterize filamentous fungi present in different stages of harvest, fermentation, drying and storage of coffee beans processed by natural method. The cherries were hand-picked and then placed on a cement drying platform where they remained until reached 11% of humidity. Microbial counts were found in all samples during fermentation and drying of the coffee beans. Counts of fungi in the coffee cherries collected from the tree (time 0) were around 1.5 x 10³ CFU/g. This number increased slowly during the fermentation and drying reaching values of 2 x 10(5) CFU/g within 22 days of processing. Two hundred and sixty three isolates of filamentous fungi were identified. The distribution of species during fermentation and drying was very varied while there was a predominance of Aspergillus species during storage period. The genera found were Pestalotia (4), Paecelomyces (4), Cladosporium (26), Fusarium (34), Penicillium (81) and Aspergillus (112) and comprised 38 different species.
Biological activities of the fermentation extract of the endophytic fungus Alternaria alternata isolated from Coffea arabica L.
(Universidade de São Paulo, Faculdade de Ciências Farmacêuticas, 2009-12) Fernandes, Maurette dos Reis Vieira; Silva, Tales Alexandre Costa e; Pfenning, Ludwig Heinrich; Costa-Neto, Cláudio Miguel da; Heinrich, Tassiela Andréa; Alencar, Severino Matias de; Lima, Marisa Aparecida de; Ikegaki, Masaharu
A total of 22 endophytic fungi isolated from coffee (Coffea arabica L.) were cultivated in vitro and their crude extracts tested. The screening was carried out using the agar diffusion method against Staphylococcus aureus, Escherichia coli and Candida albicans. The most effective isolate was Alternaria alternata, and subsequently, its extract was assayed. The total phenolic content was 3.44 μg GAE/mg of the crude extract. For the antibacterial and antifungal activity assays, minimum inhibitory concentrations (MIC) and minimum bactericidal and fungicidal concentrations (MBC and MFC) were determined. The ranges of MIC values were 50-100 μg/mL for S. aureus and 400-800 μg/mL for E. coli. The extract did not show activity in the tested concentrations for C. albicans. The fungal crude extract was assayed for antioxidant activities. Its ability to scavenge DPPH radicals and antioxidant activity by β-carotene/linoleic acid system oxidation was not significant. In addition, antitumor activity was studied using the MTT assay. At a dilution of 400 μg/mL, the extract displayed a cytotoxic activity of approximately 50% towards HeLa cells in vitro. The results indicate that endophytic fungi could be a promising source of bioactive compounds and warrant further study.
Influence of air temperature on proteinase activity and beverage quality in Coffea arabica
(Sociedade Botânica de São Paulo, 2012) Abreu, Hellen Marília Couto de; Nobile, Paula Macedo; Shimizu, Milton Massao; Yamamoto, Paula Yuri; Silva, Emerson Alves; Colombo, Carlos Augusto; Mazzafera, Paulo
Fruits were collected from trees of Coffea arabica cv. Obatã grown at Mococa and Adamantina in São Paulo State, Brazil, which are regions with marked differences in air temperature that produce coffee with distinct qualities. Mococa is a cooler location that produces high-quality coffee, whereas coffee from Adamantina is of lower quality. The amino acid and protein contents, amino acid profile, and proteinase activity and type in endosperm protein extracts were analysed. Proteinase genes were identified, and their expression was assayed. All results indicate that temperature plays a role in controlling proteinase activity in coffee endosperm. Proteinase activity was higher in the endosperm of immature fruits from Adamantina, which was correlated with higher amino acid content, changes in the amino acid profile, and increased gene expression. Cysteine proteinases were the main class of proteinases in the protein extracts. These data suggest that temperature plays an important role in coffee quality by altering nitrogen compound composition.
Ochratoxigenic fungi associated with green coffee beans (Coffea arabica L.) in conventional and organic cultivation in Brazil
(Sociedade Brasileira de Microbiologia, 2013-10-09) Rezende, Elisângela de Fátima; Borges, Josiane Gonçalves; Cirillo, Marcelo Ângelo; Prado, Guilherme; Paiva, Leandro Carlos; Batista, Luís Roberto
The genera Aspergillus comprises species that produce mycotoxins such as aflatoxins, ochratoxins and patulin. These are cosmopolitan species, natural contaminants of agricultural products. In coffee grains, the most important Aspergillus species in terms of the risk of presenting mycotoxins belong to the genera Aspergillus Section Circumdati and Section Nigri. The purpose of this study was to assess the occurrence of isolated ochratoxigenic fungi of coffee grains from organic and conventional cultivation from the South of Minas Gerais, Brazil, as well as to evaluate which farming system presents higher contamination risk by ochratoxin A (OTA) produced by fungi. Thirty samples of coffee grains (Coffea arabica L.) were analysed, being 20 of them of conventional coffee grains and 10 of them organic. The microbiological analysis was done with the Direct Plating Technique in a Dichloran Rose Bengal Chloramphenicol Agar (DRBC) media. The identification was done based on the macro and micro morphological characteristics and on the toxigenic potential with the Plug Agar technique. From the 30 samples analysed, 480 filamentous fungi of the genera Aspergillus of the Circumdati and Nigri Sections were isolated. The ochratoxigenic species identified were: Aspergillus auricoumus, A. ochraceus, A. ostianus, A. niger and A. niger Aggregate. The most frequent species which produces ochratoxin A among the isolated ones was A. ochraceus, corresponding to 89.55%. There was no significant difference regarding the presence of ochratoxigenic A. ochreceus between the conventional and organic cultivation systems, which suggests that the contamination risk is similar for both cultivation systems.

Narratives From Women Rural Workers: The Construction of Subalternity, Hierarchized Spaces and Colonial Domination
(Escola de Administração da Universidade Federal da Bahia, 2021-09-15) Dornela, Fernanda Junia; Oliveira, Cintia Rodrigues de
In this research, our aim is to analyze how gender relations are manifested in the narratives of women rural workers, in coffee farming in the Cerrado Mineiro Region, in a post-colonial perspective. It is a qualitative research, the empirical material of which consists of narrative interviews conducted with 14 rural coffee workers in the municipalities of Patrocínio, Carmo do Paranaíba and Monte Carmelo, in the state of Minas Gerais. The empirical material was submitted to the thematic analysis technique. The results suggest that gender relations are expressed through inheritances of colonialism, which constitute the themes identified: (1) constructed subordination; (2) hierarchical spaces; and (3) colonial domination.
European strategic trade policy and Brazilian export growth during the nineteenth century
(Departamento de Economia da Faculdade de Economia, Administração e Contabilidade da Universidade de São Paulo (FEA-USP), 2022-04-04) Absell, Christopher David
Until the Amazonian rubber boom, cane sugar and coffee were the two most important export commodities for Brazil during the nineteenth century. Despite inherent differences in methods of cultivation, both sugar and coffee at once benefitted and suffered from the characteristics of Brazil’s factor endowment in land, labour and capital. Yet these two export commodities demonstrated divergent growth patterns across the nineteenth century. The difference was not one of relative productivity and thus price competitiveness disadvantage, but of the imperfectly competitive nature of the international market for each commodity. European governments actively practised strategic trade policy to transfer profits from foreign to domestic or colonial firms. These market distortions were exogenous, imposed by consumer markets, and took the form of European colonial tariff preferences and subsidies to domestic production. Coffee suffered less from imperfect competition, thus remaining more profitable to Brazilian agricultural producers in the long run.
Leaf extract of Coffea arabica L. reduces lipid peroxidation and has anti-platelet effect in a rat dyslipidemia model
(Faculdade de Ciências Farmacêuticas da Universidade de São Paulo, 2022-09-02) Simões, Mario Henrique Souza; Salles, Bruno Cesar Correa; Duarte, Stella Maris da Silveira; Silva, Marcelo Aparecido da; Viana, André Luiz Machado; Moraes, Gabriel de Oliveira Isaac de; Figueiredo, Sonia Aparecida; Ferreira, Eric Batista; Rodrigues, Maria Rita; Paula, Fernanda Borges de Araújo
This study aimed to evaluate the antioxidant potential of the Coffea arabica Lineu (L.) leaf extract and its effects on platelet aggregation of dyslipidemic rats. The extract was obtained by the percolation of C. arabica L. leaves in hydroethanolic solution 70% (v/v). The mass spectrometry FIA-ESI-MS² suggested the presence of chlorogenic acid, rutin acid, and quinic acid. The DPPH• radicals scavenging capacity was demonstrated (IC50 = 0.06 mg/mL). The extract was administered to rats by gavage (300 mg/kg/day) for 56 days. Dyslipidemia was induced by administering Triton WR-1339 (300 mg/kg body weight) on the 54th day. On day 56, blood was collected by puncturing the abdominal aorta artery and the aortic artery was removed. Lipid profile, markers of renal and hepatic injury, lipid peroxidation, and platelet aggregation tests were carried out. The ingestion of extract reduced the lipid peroxidation (aorta and plasma) and platelet aggregation in dyslipidemic rats. The extract did not affect markers of renal and hepatic function as analyzed in this study, suggesting neither impaired liver nor kidney function in these animals. Therefore, our results demonstrate that the extract of leaves of C. arabica L. show antioxidant potential in vitro and in vivo as well as anti-platelet aggregation in dyslipidemic animals.

(Sociedade Brasileira da Ciência das Plantas Daninhas, 2022-09-30) Rodrigues, Rafael J. A.; Carvalho, Gladyston R.; Gonçalves, Adenilson H.; Carvalho, João Paulo F.; Alcântara, Elifas N. de; Resende, Laís S.
Background Phytosociological surveys of weeds in agricultural regions, such as the coffee growing Cerrado Mineiro Denomination, are essential for understanding the predominant species in a cultivation area. Objective This study aimed to determine the predominant weed species in coffee crops in Cerrado Mineiro through phytosociological surveys during two periods of the year. Methods 26 coffee farms in 12 municipalities within the Cerrado Mineiro Denomination of Origin of were visited. The inventory square method was used for the phytosociological surveys. In each area, 40 m2 was evaluated and divided into two study periods (summer and winter). Calculations of the variables were performed using the following data: frequency, density, abundance, importance value index, similarity coefficient, rarefaction curve, Shannon index, and hierarchical grouping analysis using Jaccard’s similarity. Results In the summer (rainy period), 54 species from 16 families were found, with Poaceae, Asteraceae, and Amaranthaceae predominating. In winter (dry season), 56 species from 16 families were found, predominantly Asteraceae, Poaceae, and Brassicaceae. There was a predominance of 17 and 16 species, with similarity levels (Jaccard) of 45.58% and 40.78% for summer and winter, respectively. Conclusions The weed community in the Cerrado Mineiro coffee plantation is dominated by two main families, Poacaeae and Asteraceae, with Eleusine indica (summer) and Conyza spp. (winter) being the species with the highest importance values.

Para este estudo foi adotada a pesquisa qualitativa, com a realização de entrevistas, sendo todas feitas pela plataforma do Google Meet. Ao final, constatou-se que a experiência de turismo cafeeiro realizada em Taquaritinga atende às dimensões propostas por Goolaupa e Mossberg (2017), além de outros aspectos, como, por exemplo, perceber que as atividades do referido setor têm ajudado no desenvolvimento da economia de Taquaritinga.
O café sombreado da serra de Baturité, Ceará, Nordeste do Brasil: gestão ambiental, sustentabilidade e impactos eco-ssocioeconômicos
(Universidade do Vale do Itajaí, 2023-09-15) Ribeiro, Sofia Regina Paiva; Lima, Filipe Augusto Xavier; Loiola, Maria Iracema Bezerra
O café sombreado da serra de Baturité, uma das poucas plantações no Brasil que integram lavoura-floresta, configura-se como uma antítese ao modelo agrícola predominante em nosso país, em monocultivo. Conhecido como “café de Baturité”, é apreciado por ser originário da variedade típica da espécie arábica (Coffea arabica) sombreada, com produção realizada por pequenos produtores rurais familiares, de forma agroflorestal. Diante desse cenário, o presente artigo objetiva verificar o impacto da revitalização da cultura do café de sombra na serra de Baturité a partir de iniciativas voltadas para o turismo, preservação ambiental e desenvolvimento socioeconômico regional. O procedimento metodológico adotado contempla estudo bibliográfico, observação participante e entrevistas semiestruturadas, com fontes-chave. Para tanto, as informações foram catalogadas, analisadas e confrontadas através da triangulação dos dados. Os resultados evidenciam que a cafeicultura, inserida na região há dois séculos (1822-2022), se encontra em fase de revitalização. Essa revalorização do cultivo, agora com conhecimentos empírico e técnico, vem contribuindo para minimizar o impacto antrópico na prática agrícola serrana, ampliar a gestão socioambiental nas propriedades rurais (onde o café se tornou um vetor de desenvolvimento sustentável) e fomentar a economia regional, como se observa a partir das ações voltadas para o ecoturismo, o empreendedorismo rural e a economia circular.
Informações e inovação na rede social de produtores de café ecológico – Ceará
(Universidade Estadual de Campinas, 2024-08-16) Braga, Francisco Laercio Pereira; Campos, Kilmer Coelho; Lima, Filipe Augusto Xavier; Ribeiro, Luiz Carlos de Santana
Este trabalho constrói e analisa a estrutura da rede social de produção de café sombreado/ecológico da região do Maciço de Baturité, no Estado do Ceará. Para tanto, foram realizadas pesquisas de campo e estudo de caso com 36 produtores de café ecológico dos municípios de Mulungu, Baturité e Guaramiranga, aplicando-se o conceitual de Análise de Redes Sociais (ARS). Os principais resultados mostram que a densidade da rede da região ficou em 6,7%. Isso reforça o argumento de que as informações circulam em menor velocidade e de que há pouca interação dos atores da rede para troca de ideias, experiências, erros e acertos individuais e coletivos, fator limitante para o conhecimento de inovações implementadas por outros produtores locais. A atuação das universidades, associações de produtores, poder público e instituições de apoio são importantes para troca de informações sobre produção e comercialização do café ecológico e para estimular as inovações a serem exploradas.
