Análisis de intensidades energéticas y emisiones de CO2 a partir de la matriz de contabilidad social de Andalucía del año 2000 AgEcon
Cardenete, Manuel Alejandro; Fuentes Saguar, Patricia D.; Polo, Clemente.
RESUMEN: En este artículo se estiman las intensidades energéticas y emisiones de CO2 para la economía andaluza en el año 2000. Las intensidades energéticas de las ramas productivas se calculan en varios escenarios empleando un modelo SAM especificado con la matriz de contabilidad social elaborada por los autores. Las emisiones se estiman con el modelo input-output, distinguiendo la polución intermedia de la originada por la demanda final. Los resultados muestran la existencia de importantes variaciones en intensidades entre ramas y también las sustanciales variaciones que acaecen al endogeneizar el consumo y la inversión. La estimación de las emisiones en el año base resulta bastante satisfactoria y las simulaciones realizadas muestran el sustancial...

Análisis del impacto medioambiental derivado de las actividades económicas. Aplicación a una economía regional AgEcon
Flores, Monica; Mainar, Alfredo J..
The goal of this paper is to analyse the households’ environmental impact in a regional economy, including the household direct impact as well as the impact associated with the production of goods and services of the household demand. Moreover, per capita ecological impacts for each household category according to income level are obtained. We focus on water consumption, and water and atmospheric pollution. The framework is based on a regional SAMEA (Social Accounting Matrix and Environmental Accounts), and vertically integrated environmental indicators using the Leontief model. An application is carried out for the Aragon case.

Assessing Sustainability: Some Conceptual and Empirical Challenges AgEcon
Toman, Michael; Lile, Ronald D.; King, Dennis M..
In this paper we address two related conceptual and practical challenges in assessing "sustainability." The first is the criteria to be used, in particular the relationship between sustainability and measures of economic well-being and the use of monetary versus nonmonetary indicators. The second is the problem of determining which physical scales to use for sustainability assessments when there are multiple and overlapping "communities" or stakeholder groups. While neither set of challenges admits a definitive solution, there has been progress on the first set of issues - in particular, through the development of multicriteria assessment strategies and stakeholder involvement processes. In contrast, the problem of how to assess sustainability in practice...

Assessing the 2003 CAP Reform: Sensitivity to the Decoupling of Agenda 2000 Direct Payments AgEcon
Gohin, Alexandre.
The European Union decided in June 2003 a new reform of its farm policy with a new step toward the decoupling of farm income support instruments. Available impact studies find that this reform will reduce production incentives, substantially for beef and to a lesser extent for arable crops. All these studies assume that the Agenda 2000 arable crop direct payments are already mostly decoupled while beef premiums are much more linked to production. Our main objective in this paper is to test the sensitivity of these results to this questionable modelling of Agenda 2000 direct payments which neglects eligibility rules and land market imperfections. Our analysis reveals that the negative effects of the reform on both arable crop and beef production are not...

Inter-sectoral Water Use in South Africa: Efficiency Versus Equity AgEcon
Juana, James S.; Kirsten, Johann F.; Strzepek, Kenneth M..
While water supply sources are dwindling in South Africa, the demand for the scarce water resource is increasing. This situation requires a switch from supply to demand management of water in the country. The study updates the 1999 social accounting matrix for South Africa, using the Trade and Industrial Policy Strategies (TIPS) time series data, STATSA's 2001 census report and 2000 water accounts, the 2002 national income accounts, published by the South African Reserve Bank (SARB) and the Water Resource Management Strategy (WRMS) registration data. Using the updated SAM, the contribution of water to economic development in South Africa is estimated through the traditional SAM multiplier analysis. The paper then investigates the impact of reallocating...

Las emisiones de metano (CH4) en el subsistema agroalimentario catalán: un análisis input-output alternativo AgEcon
Navarro, Francisco; Alcantara, Vicent.
In this paper we carry out a research of the CH4 emissions related to the Catalan agro-food sector through an alternative or at least complementary, input-output subsystems analysis, which is a useful tool to study the productive structure of the different sectors that make up an economy. The application of this technique allows the decomposition of the subsystem in different effects depending on the existing interindustry linkages with all the production sectors of the economy inside as well outside the subsystem. Results highlights the relevance of intrasectorial relations within the agro-food industry subsystem, which shows a significant autonomy respect to this type of emissions with regard to the rest of the economy. This feature guides the sort of...

Regional and Sector Environmental Efficiency Empirical Evidence from Structural Shift-share Analysis of NAMEA data AgEcon
Mazzanti, Massimiliano; Montini, Anna.
This paper provides new empirical evidence on regional–national disparities in environmental efficiency, based on case studies of Italy and the Lazio region, which includes the city of Rome. Shift-share analyses provide evidence on the drivers of environmental efficiency and on sector specificity. This confirms the usefulness of this method for studying the environmental economics realm, in order to investigate structural and efficiency factors at the level of within country environmental efficiency performance, even in light of the different shares of services. Our evidence shows that although the Rome region has achieved higher environmental performance compared to Italy mainly thanks to its being less industry based, some critical points in the energy...

Relações sinérgicas e efeitos sobre a produção setorial no sistema inter-regional Paraná-Restante do Brasil AgEcon
Rodrigues, Rossana Lott; Moretto, Antonio Carlos; Sesso Filho, Umberto Antonio; Kureski, Ricardo.
The present article has as objective to calculate and to analyze the level of the synergic interactions and the overflow of the multiplying effect of the sectorial production between Parana and the Rest of Brazil (Brazil except Parana), using interregional systems of input-output estimated for the years of 1995 and 2000. The main results showed that: a) the dependence of the production of Parana in relation to the flow of trade with the Rest of Brazil raised from 25% in 1995 to 33% in 2000; b) only 1.36% of the production of the Rest of Brazil depended on the flow of input (goods and services) between this and Parana in 1995, reducing this dependence to 0,56% in 2000; c) the overflowing average of the multiplier effect of the production of the sectors of...
