Última Perception of risk sources by chilean blueberry producers Rev. Bras. Frutic. Lobos,Germán; Schnettler,Berta; Mena,Carlos; Ormazábal,Yony; Cantillana,Juan Carlos; Retamales,Jorge Borrar. Abstract The biological and environmental nature of the agricultural production implies that growers operate in an environment of greater risk as compared to other economic activities. This has implications on the manner in which the growers can manage the risks inherent to their activity, which depends on how they perceive the risks and on the degree of aversion to risk. The main objective of this study was to learn about the perception of the main sources of risk that blueberry growers face in the Maule Region, Chile. This Region has about 25% of the planted area of this species in Chile. We used information from questionnaires implemented in 124 fields which considered two independent groups of growers: 48 owners and 76 managers. A scale of Importance...

Dentro del proceso de establecimiento de las líneas de desarrollo estratégico para la actividad agrícola, la geomática y sus diversas tecnologías permiten generar una caracterización altamente representativa y confiable del territorio, expresada en una base de datos digital dinámica y flexible, que propicia la planificación y el seguimiento de los cambios productivos observados en los terrenos beneficiados con el incremento del agua de riego y el mejoramiento de su red de distribución. El objetivo principal de la investigación fue crear un Sistema de Información Geográfica (SIG), alimentado con información base agropecuaria y socioeconómica, que permita la identificación de sectores homogéneos de intervención y el establecimiento de la tipología de las...

Ano: 2007 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0365-28072007000100006 Current and potential distribution areas for Nothofagus alessandrii, an endangeredtree species from central Chile Ciencia e Investigación Agraria Santelices,Rómulo; Drake,Fernando; Mena,Carlos; Ordenes,Rodrigo; Navarro-Cerrillo,Rafael M. Nothofagus alessandrii ("ruil") is an endangered species native to the Maule Coastal Forest of central Chile. Previous studies have demonstrated that the current distribution of this species and rates of deforestation and fragmentation present a serious threat to the species. To address this threat, spatial and temporal variation in remnant "ruil" forest cover was analyzed for the period from 1991 to 2008. Using aerial photography and geomatic tools, the state of "ruil" forests cover in 1991 was compared to the "ruil" forests cover in 2008 and with this information, the potential distribution area of this species was calculated. The results demonstrate that the current area of "ruil" forest is approximately 314 ha, with a net loss of 42 ha (12% of the...
