ABSTRACT The objective of this study was to identify different market segments for buffalo meat with target groups defined in the city of Belém, Pará, Brazil. Paired samples of beef and buffalo meat were given to 447 volunteers, and a sensory analysis of the products was conducted. After the tasting, a questionnaire was administered to obtain demographic (age, educational level, marital status) and economic (household income) data as well as information on the habits of respondents and preferences regarding buffalo meat. The factors were estimated using the principal components method and the factors with characteristic roots greater than one were extracted. To check the suitability of the factorial model, Bartlett’s sphericity test and the Kaiser-Meyer-Olkin (KMO) test were used. A factor analysis was performed, identifying five factors with common variability dimensions. The study has helped identify four distinct market segments which, combined with a targeted marketing strategy, can be used to leverage the productive chain: I - Young and interested, II - Mixed and indifferent, III - Graduates and successful, and IV - Healthy women. All had positive responses to buffalo meat; clusters I and III stood out with regard to several indicators, especially those related to the preference for buffalo meat and the predisposition to purchase and include it in meals. The sensory analysis indicated that consumers showed a greater acceptance of buffalo meat based on the characteristics of flavour, colour, succulence and tenderness. The study helps to identify market segments with distinct features that, combined with a targeted marketing strategy, can be used to leverage the supply chain.

O açaí é um dos principais alimentos da população paraense e de maior consumo per capita em 2010. A venda de açaí em Belém é realizada por diversas unidades que operam no mercado varejista. O objetivo deste trabalho foi identificar os segmentos de mercado: quitandas, microempreendedores e supermercados, a partir da análise de um conjunto de variáveis que definem as decisões dos consumidores de açaí. Utilizou-se do método stepwise da análise discriminante múltipla para estimar as funções discriminantes. Os resultados mostram que o segmento identificado com maior precisão foi o de quitandas, com 100%, seguido do segmento de supermercado com 96,5% dos casos classificados corretamente, e o segmento de microempreendedores, com 90,9%, apresentou a menor precisão no enquadramento dos consumidores. O modelo estimado apresentou elevada significância no processo de estimação, uma vez que as funções, incluindo as variáveis quantidade de açaí, renda dos consumidores, preço do açaí, qualidade do açaí, preço do peixe e preço da farinha, classificaram corretamente 95,6% dos elementos originais.

Açaí pulp is one of the main foods in the State of Pará and of higher per capita consumption in 2010. The sale of açaí in Belém is carried out by several units that operate in the retail market. The objective of this study was to identify market segments: greengrocers, micro entrepreneurs and supermarkets, from the analysis of a set of variables that define the decisions of açaí consumers. The stepwise multiple discriminant analysis was used to estimate the discriminant functions. Results show that the segment identified with greater precision was the greengrocery, with 100%, followed by supermarkets, with 96.5% of the cases accurately classified, and the segment of micro entrepreneurs, with 90.9%, had the lowest accuracy in the consumer classification. The estimated model showed a high significance in the estimation process, since the functions with the variables amount of açaí, consumer income, price of açaí, quality of açaí, price of fish and price of flour, correctly classified 95.6% of the original elements.

O objetivo deste trabalho foi estimar o valor econômico e a margem de comercialização da madeira em tora oriunda de áreas manejadas. Essa cadeia, além de produzir margem positiva, os valores são relativamente superiores aos gerados nas atividades que concorrem para o desmatamento na Amazônia para se estabelecerem. Adicionalmente, determinou-se o coeficiente médio de desdobramento de 37,3% (2,68 m³ de madeira em tora para cada 1,0 m³ de madeira serrada), o qual revelou baixo grau tecnológico das empresas. O valor econômico médio da extração e comercialização da madeira em pé no mercado local foi de R$ 23,48/m³, tendo um valor mínimo de R$ 9,06/m³ para as espécies da categoria C4 (madeira branca) e um máximo de R$ 55,63/m³ para as espécies da categoria C1 (madeira especial). Assim, para um fluxo de 30 anos e extração de 25 m³/ha nos planos de manejo das áreas de concessão florestal do Estado do Pará, gera-se um valor médio de R$ 587,00/ha, ou R$ 19,56/ha/ano. No fluxo de 30 anos, esse resultado é relativamente superior ao gerado pelas atividades de pecuária extensiva (em torno de R$ 180,00/ha) e das lavouras de grãos (em torno dos R$ 420,00/ha), principais responsáveis pelo desmatamento da Amazônia. Também, apresenta maior rentabilidade do que o reflorestamento com paricá, que gera R$ 192,26/ha. A margem de comercialização indicou que a sociedade tende a se apropriar de 14,3% do valor econômico gerado na cadeia da madeira oriunda dos contratos de concessão florestal.

The objective of this study was to estimate the economic value and the trade margin of roundwood from managed areas. Besides generating a positive margin values, they are relatively higher In this chain than those generated in activities contributing to deforestation in the Amazon. Additionally, the unfolding mean rate of 37.3% was achieved (2.68 m³ of logs for each 1.0 m³ of sawn timber), which revealed a low technological level of companies. At the lower Amazon, the average economic value from the extraction and sale of standing timber in the local market was R$ 23.48/m³, with a minimum value of R$ 9.06/m³ for the species in category C4 (softwood) and a maximum of R$ 55.63/m³ for the species of category C1 (special wood). Thus, considering an extraction flow of 30 years and assuming the extraction of 25 m³/ha in management designs of forest areas from concession contracts in the state of Pará, it is generate an average economic value of R$ 587.00/ha or R$ 19.56/ha/year, which is relatively higher than the profit generated by the activities of extensive livestock (around R$ 180.00 per hectare or R$ 6.00/ha/year) and grain crops (approximately R$ 420.00 per hectare or R$ 14.00/ha/year), which are the main responsibles for deforestation in the Amazon. It also presents a higher profitability than the reforesting with Paricá, whose income is R$ 192.26/ha or R$ 7.12/ha/year. The marketing margin showed that society tends to appropriate of 14.30% of the economic value generated in the wood chain from the transition contracts.
