Aggregate eco-efficiency indices for New Zealand – a Principal Components Analysis

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 five aggregate measures over the period 1994/95 to 1997/98. The worsening of the other aggregate measures reflects, among other things, the relatively poor performance of the primary production and related processing sectors. These results show PCA is an effective approach for aggregating eco-efficiency indicators and assisting decision makers by reducing redundancy in an eco-efficiency indicators matrix.Policy development, policy evaluation, Aggregate indices, Agricultural and Food Policy, Community/Rural/Urban Development, Crop Production/Industries, Environmental Economics and Policy, Farm Management, Land Economics/Use,

APORTES DE LA EDUCACIÓN SUPERIOR PARA EL DESARROLLO SOSTENIBLE - LA EXTENSIÓN UNIVERSITARIA Y LA PERTINENCIA DEL CONOCIMIENTO

En este mundo complejo el modelo de desarrollo actual basado primordialmente en el beneficio económico, deja dudas acerca de su posibilidad de dar respuestas de orden social, para una mayoría necesitada seres humanos. El Desarrollo Sostenible emerge como un enfoque diferente para el progreso social de nuestras regiones, enmarcada en la propuesta posmoderna . La Educación Superior Venezolana, a través de una política adecuada de extensión universitaria puede ayudar a formar los nuevos ciudadanos y lideres de nuestra nación, en contacto directo con esas necesidades, de manera que puedan impulsar el desarrollo social de nuestro país, con respeto por el desarrollo social de las futuras generaciones.AbstractIn this complex world the actual model for development, based on fundamentally the economics benefit, its showing a lot of problems about its capabilities to give answer to a great majority of needed human beings. Sustainable development shows a new point of view, for the development of ours regions, sustained in the postmodern proposal. The Venezuelan higher education, through an adequate extension politic, could help to form the new citizens and leadership, in close contact with those needs, so it can impulse the social development of our country, with respect for the social development of future generations
