Última Aggregate eco-efficiency indices for New Zealand – a Principal Components Analysis AgEcon Jollands, Nigel; Lermit, Jonathan; Patterson, Murray. Eco-efficiency has emerged as a management response to waste issues associated with current production processes. Despite the popularity of the term in both business and government circles, limited attention has been paid to measuring and reporting eco-efficiency to government policy makers. Aggregate measures of eco-efficiency are needed, to complement existing measures and to help highlight important patterns in eco-efficiency data. This paper aims to develop aggregate measures of eco-efficiency for use by policy makers. Specifically, this paper provides a unique analysis by applying principal components analysis (PCA) to eco-efficiency indicators in New Zealand. This study reveals that New Zealand's overall eco-efficiency improved for two out of the...

Ano: 2004 URL: http://purl.umn.edu/97773 Physical attributes of Cambisol in apple ( Malus domestica Borkh. cv. Gala) orchard under different weed management systems in Urubici- Santa Catarina, Brazil Acta Agron. (Palmira) Schmitz,Daniela; Loss,Arcângelo; Oliveira,Bruno Salvador; Lovato,Paulo Emilio; Veiga,Milton da; Brunetto,Gustavo; Curmi,Pierre; Comin,Jucinei José. Abstract The aim of this research was to evaluate the physical attributes of Cambisol in apple (Malus domestica Borkh. cv. Gala) orchard under different weed management systems in the state of Santa Catarina (SC), Brazil. The treatments were as follows: control (no weed management), chemical desiccation and mowing. We took samples of undisturbed soil at depths of 0-5, 5-10, 10-15 and 15-20 cm. We evaluated hydraulic conductivity (HC); bulk density (BD); soil penetration resistance (Pr); total porosity (TP), macropores (MaP), micropores (MiP); soil aggregation indices such as arithmetic and geometric mean diameter of air-dried and water-stable aggregates (AMDad, AMDws, GMDad, GMDws, respectively); aggregate stability index (ASIAMD and ASIGMD) and volumetric...
