Balance de carbono y tasa de descomposición de mantillo y horizontes de fermentación de suelos forestales.
Provedor de dados: 32
Autores: Barrales Brito, Edgar.
El mantillo y horizontes de fermentación (CF) es un reservorio dinámico de carbono (C) en suelos forestales. Las metodologías que cuantifican la emisión de CO2 por la descomposición son escasas y requieren periodos largos de medición. Se requieren métodos para poder generar información de la emisión de CO2 de éstas capas orgánicas en tiempos cortos de medición. Los objetivos fueron: generar un protocolo para la medición de la emisión de CO2 por la descomposición de mantillo y CF con un respirómetro manométrico (OxiTop ®). Medir los reservorios de C de mantillo y CF de bosques con diferentes condiciones. Medir la emisión de CO2 del mantillo y CF y las tasas de descomposición con un respirómetro. Analizar las características químicas de los mantillos y...

INTEGRATED ENVIRONMENTAL FOOTPRINT INDEX (IEFI): MODEL DEVELOPMENT AND VALIDATION

ABSTRACT: Freshwater is a valuable resource worldwide given the growing demand of the global population. This study aimed to develop and validate an integrated assessment model by means of environmental footprint indices (water, ecological, and carbon), which measure the environmental sustainability of heterogeneous communities, people, and countries. An environmental footprint was firstly defined as a set of indicators to track human pressure on planet Earth under different angles, being a multidimensional index of environmental sustainability. A Delphi survey was used to bring together opinions from a diverse set of experts. The participants of this study consisted of 120 experts from several fields of knowledge belonging to the best-known research and...

CO2 emissions, energy consumption and economic growth in Tunisia
Provedor de dados: 31
Autores: Chebbi,   Houssem Eddine; Boujelbene,   Y.
The aim of this country specific study is to understand long and short-run linkages between economic growth, energy consumption and CO2 emission using Tunisian data over the period 1971-2004. Statistical findings indicate that economic growth, energy consumption and CO2 emission are related in the long-run and provide some evidence of inefficient use of energy in Tunisia, since environmental pressure tends to rise faster than economic growth. In the short run, results support the argument that economic growth exerts a positive “causal” influence on energy consumption growth. In addition, results from impulse response do not confirm the hypothesis that an increase in pollution level induces economic expansion. Although Tunisia has no commitment to reduce...

Designing Carbon Taxation Schemes for Automobiles: A Simulation Exercise for Germany
Provedor de dados: 31
Autores: Adamou,   Adamos; Clerides,   Sofronis; Zachariadis,   Theodoros.
Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon vehicles and give a rebate to purchasers of low-carbon automobiles.  e estimate a discrete choice model of demand for automobiles in Germany and simulate the impact of alternative feebate schemes on emissions, consumer welfare, public revenues and firm profits. The analysis shows that a well-designed scheme can lead to emission reductions without reducing overall welfare.

Climatic changes: what if the global increase of CO2 emissions cannot be kept under control?
Provedor de dados: 56
Autores: Barreto de Castro,L.A.
Climatic changes threaten the planet. Most articles related to the subject present estimates of the disasters expected to occur, but few have proposed ways to deal with the impending menaces. One such threat is the global warming caused by the continuous increase in CO2 emissions leading to rising ocean levels due to the increasing temperatures of the polar regions. This threat is assumed to eventually cause the death of hundreds of millions of people. We propose to desalinize ocean water as a means to reduce the rise of ocean levels and to use this water for populations that need good quality potable water, precisely in the poorest regions of the planet. Technology is available in many countries to provide desalinated water at a justifiable cost...
