| In Amazonia, the main causes of deforestation are systems based on slash-and-burn agriculture. The objective of this work was to evaluate temporal changes in the soil chemical attributes after the vegetation has been slashed and burned in an area of native forest in the Western Amazon. For this study, four hectares of forest in Cruzeiro do Sul, State of Acre, Brazil, was slashed and burned. The soil in the study area was classified as Ultisol (Argissolo Amarelo Distrófico típico). Soil samples were collected over the course of one year, the first one being collected 16 hours after the burn and the others at 30, 60, 90, 150, 210, 270, and 360 days after the burn. The soil surface layers were more sensitive to fire action. Ashes from vegetation burn... |

| El objetivo de esta investigación fue a de identificar las estrategias adoptadas por las vinícolas en Brasil, en la región de las ciudades de San Roque, Louveira, Jundiaí y Sao Paulo. La metodología utilizada fue el estudio de casos múltiples. Fueron realizadas entrevistas con los propietarios y visitas a las vinícolas. El turismo rural es el principal canal de distribución para los vinos, licores, frutas y dulces, Están presentes en las vinícolas una diversificación de actividades, como tiendas, restaurantes y hacer un recorrido a las vinícolas. Los propietarios se caracterizan por ser pequeños agricultores familiares y descendientes de italianos y sus familias están en esta actividad por 2-3 generaciones. Las vinícolas buscan crear un paisaje rural dónde... |
