The municipality evaluated is São Gabriel do Oeste, located in the state of Mato Grosso do Sul, Brazil. In the 1960's the region was occupied by migrants from southern Brazil who have converted native vegetation (savanna) into extensive cattle and monocrops (coffee, cotton, soybeans and corn, successively), and more recently intensive swine was introduced. The following emergy indicators were calculated for the current municipal situation: Renewability (%R): 8%; Emergy yield ratio (EYR): 14; Emergy investment ratio (EIR): 0.08; Environmental loading ratio (ELR): 11; Emergy exchange ratio (EER): 13 and Transformity of the commodities: 8x105seJ.J-1. The very low %R and high environmental pressure (ELR) signalize that the municipality's economy is highly dependent on external inputs. Above all, there is a high loss of system internal stocks (soil) and the high EYR obtained is directly related to this predatory land use. The emergy value of the soil loss is 83% of the total emergy, which is an environmental imbalanced situation. The main land use in São Gabriel do Oeste, accounting for 39% of the territory, is extensive cattle farming that demands few agricultural inputs, what explains the very low EIR. The EER shows that the rural area is subsidizing urban economies that import products from the study area. The real value of the agricultural products should be 13 times the market value of such commodities to be considered as a fair trade. The inclusion of soil loss as a negative externality shows that (in economic terms) the amount of soil lost by erosion and leaching (4,149x106 emUSD.year-1) corresponds to 46% of the total production monetary value (9,018x106 emUSD.year-1). The emergy diagnosis shows that the business model established for commodities producers is highly dependent on the external market, which does not remunerate the imported resources accordingly to its real value. To settle this situation, a dialogue between farmers, consumers and authorities should be established. The latter two should involve not only local representatives as well as players of the importing countries.

Para atender à crescente demanda por derivados do fruto de açaí, tem havido uma expansão do cultivo comercial do açaizeiro, resultando na intensificação da procura por mudas de qualidade dessa espécie. O objetivo deste trabalho foi avaliar o efeito de diferentes tamanhos de recipientes sobre o crescimento inicial de mudas de Euterpe precatoria. O experimento foi conduzido com 50% de sombreamento, no viveiro do campo experimental da Embrapa Acre, Rio Branco, AC, no delineamento experimental em blocos casualizados, com cinco tratamentos e quatro repetições de oito plantas. Os tratamentos foram compostos por diferentes tamanhos de recipientes: saco pequeno (P) de 10 cm x 20 cm; saco médio (M) de 15 cm x 22 cm; saco grande (G) de 18 cm x 25 cm; saco extragrande (EG) de 20 cm x 30 cm; e tubete (TB) de 0,28 L. As plantas foram avaliadas quanto à altura, diâmetro do colo, relação altura-diâmetro e número de folhas. Os dados obtidos foram submetidos à análise de variância e as médias dos tratamentos foram comparadas pelo teste de Tukey. Aos 120 dias após a repicagem, mudas de E. precatoria produzidas em tubetes de 0,28 L apresentaram as melhores caraterísticas morfológicas. |
