Environmental management problems, future generations and social decisions

The decisions of many individuals and social groups, taking according to well-defined objectives, are causing serious social and environmental problems, in spite of following the dictates of economic rationality. There are many examples of serious problems for which there are not yet appropriate solutions, such as management of scarce natural resources including aquifer water or the distribution of space among incompatible uses. In order to solve these problems, the paper first characterizes the resources and goods involved from an economic perspective. Then, for each case, the paper notes that there is a serious divergence between individual and collective interests and, where possible, it designs the procedure for solving the conflict of interests. With this procedure, the real opportunities for the application of economic theory are shown, and especially the theory on collective goods and externalities. The limitations of conventional economic analysis are shown and the opportunity to correct the shortfalls is examined. Many environmental problems, such as climate change, have an impact on different generations that do not participate in present decisions. The paper shows that for these cases, the solutions suggested by economic theory are not valid. Furthermore, conventional methods of economic valuation (which usually help decision-makers) are unable to account for the existence of different generations and tend to obviate long-term impacts. The paper analyzes how economic valuation methods could account for the costs and benefits enjoyed by present and future generations. The paper studies an appropriate consideration of preferences for future consumption and the incorporation of sustainability as a requirement in social decisions, which implies not only more efficiency but also a fairer distribution between generations than the one implied by conventional economic analysis.

Environmental regulation: choice of instruments under imperfect compliance

Compliance is an important issue in environmental regulation. In this paper, we discuss some of the key elements of the problem and analyze a situation where emissions are not random and firms are risk-neutral. We study the firm's decision on emissions and compliance when the environmental regulation is based on standards and the enforcement agency audits the firm with a certain probability. We then compare total emissions when environmental regulation is based on different instruments: standards, taxes, and tradable permits. We show that when compliance is an issue, environmental taxes are superior to the other instruments. We also analyze the (static) efficiency of the solution.

Memoria – beca BE2005

Report for the scientific sojourn at the Centre for Interdisciplinary studies in Environment and Development (CISED), located in Bangalore (Southern India), from September to December 2005. A field-work in the South Indian city of Chennai (former Madras) was developed to analyse the mounting urban (and peri-urban) water crisis. In view of tackling this matter, the state government has done a deal to construct a 100 million litres per day seawater desalination plant. Due to its relative energy-intensiveness (compared to conventional water supply means), the fact that such a large capacity plant will be located in poor country such as India, constitutes somewhat of a surprising novelty, as most desalination facilities in the world are to be found in the oil-rich Persian Gulf countries. This work faces the environmental impact, the energy-intensive technology required, the cost and the missed water management options

La información televisiva durante la crisis del Prestige. Anàlisis de contenido de los noticiarios de TVE1, TV3, Antena 3 y telecinco

La catàstrofe mediambiental generada per l’enfonsament del petroler Prestige enfront de les costes gallegues al 2002 ha estat un dels majors desastres ecològics a Espanya i les seves conseqüències es van estendre al terreny polític i social, generant una situació de crisi sense precedents al territori espanyol. Aquest treball de recerca inclou el marc teòric, la metodologia i els primers resultats de l’estudi de la informació televisiva emesa per quatre cadenes generalistes de televisió durant tota la crisi. A més d’una revisió crítica de les teories de la comunicació i els seus mètodes d’investigació, s’ofereix un estudi sobre el concepte i l’estructura del noticiari televisiu, així com unes notes introductòries sobre la cobertura de cada cadena.

Payments for environmental services in watersheds: insights from a comparative study of three cases in Central America

We have compared three cases of payments for water-related environmental services (PES) in Central America, in terms of socioeconomic background, opportunity costs of forest conservation and stakeholders’ perceptions on the conditions of water resources and other issues. We found that, in general, the foregone benefits from land uses alternative to forest cover are larger than the amount paid, which apparently contradicts the economic foundation of PES schemes. A number of possible explanations are explored. The results also suggest that trade-offs between different environmental and social goals are likely to emerge in PES schemes, posing some doubts on their ability to be multipurpose instruments for environmental improvement and rural development. We also found that PES schemes may work as a conflictresolution instrument, facilitating downstream -upstream problem solving, though at the same time they might introduce changes in social perceptions of property rights.

Between specialization and globalization. The marketing of agrarian products and its environmental impacts seen from a historical perspective: the province of Barcelona in the mid-nineteenth century

Ecological economics has five good reasons to consider that economic globalisation, spurred by commercial and financial fluxes, to be one of the main driving forces responsible for causing environmental degradation to our planet. The first, is the energy consumption and the socio-environmental impacts which long-distance haulage entails. The second, is the ever-increasing flow of goods to far-away destinations which renders their recycling practically impossible. This is particularly significant, because it prevents the metabolic lock of the nutrients present in food and other agrarian products from taking place. The third, is that the high degree of specialization attained in agriculture, forestry, cattle, mining and industry in each region, generates deleterious effects not only on the eco-landscape structure of the uses of the soil, but on the capability to provide habitat and environmental functions to maintain biodiversity as well

The Appraisal of projects with environmental impacts. Efficiency and Sustainability

It is usually assumed that the appraisal of the impacts experienced by present generations does not entail any difficulty. However, this is not true. Moreover, there is not a widely accepted methodology for taking these impacts into account. Some of the controversial issues are: the appropriate value for the discount rate, the choice of the units for expressing the impacts, physical or monetary units -income, consumption or investment- and the valuation of tangible and intangible goods. When approaching the problem of very long term impacts, there is also the problem of valuing the impacts experienced by future generations, through e.g., the use of an intergenerational discount rate. However, if this were the case, the present generation perspective would prevail, as if all the property rights on the resources were owned by them. Therefore, the sustainability requirement should also be incorporated into the analysis. We will analyze these problems in this article and show some possible solutions.

Environmental Kuznets Curves for Carbon Emissions: A Critical Survey

The empirical finding of an inverse U-shaped relationship between per capita income and pollution, the so-called Environmental Kuznets Curve (EKC), suggests that as countries experience economic growth, environmental deterioration decelerates and thus becomes less of an issue. Focusing on the prime example of carbon emissions, the present article provides a critical review of the new econometric techniques that have questioned the baseline polynomial specification in the EKC literature. We discuss issues related to the functional form, heterogeneity, “spurious” regressions and spatial dependence to address whether and to what extent the EKC can be observed. Despite these new approaches, there is still no clear-cut evidence supporting the existence of the EKC for carbon emissions. JEL classifications: C20; Q32; Q50; O13 Keywords: Environmental Kuznets Curve; Carbon emissions; Functional form; Heterogeneity; “Spurious” regressions; Spatial dependence.Residential satisfaction is often used as a barometer to assess the performance of public policy and programmes designed to raise individuals' well-being. However, the fact that responses elicited from residents might be biased by subjective, non-observable factors casts doubt on whether these responses can be taken as trustable indicators of the individuals' housing situation. Emotional factors such as aspirations or expectations might affect individuals' cognitions of their true residential situation. To disentangle this puzzle, we investigated whether identical residential attributes can be perceived differently depending on tenure status. Our results indicate that tenure status is crucial not only in determining the level of housing satisfaction, but also regarding how dwellers perceive their housing characteristics. Keywords: Housing satisfaction, subjective well-being, homeownership. JEL classification: D1, R2.

La revolución energética cubana en la UCLV: ¿un paso en el camino hacia la sostenibilidad?. Parte I: Análisis de los impactos ambientales

La Revolución Energética Cubana (REC) surge de las necesidades de resolver la situación social y económica de Cuba, sumergida en una crisis energética con constantes apagones que limitaban por completo todo desarrollo del país. La REC (2006) se basa en los principios de la autosuficiencia energética, el ahorro y uso racional de la energía, y el incremento de la eficiencia en todos los aspectos. En el presente trabajo se realiza el análisis de la sostenibilidad socio-ambiental de la REC en la Universidad Central Marta Abreu de Las Villas (UCLV), ubicada en Santa Clara (Cuba). La valoración se ha efectuado mediante el análisis de los impactos ambientales y sociales en dos estudios paralelos que se complementan aplicando la técnica de conmensurabilidad débil. El conjunto de los programas de la REC han propiciado mejoras en el suministro eléctrico y en el ahorro energético, disminuyendo en un 44% las emisiones de CO2, a pesar del incremento en la actividad docente y en la flota de equipos. Las medidas adoptadas han incidido en la calidad de la docencia, las condiciones de vida, la concienciación y la participación de la población, dando lugar a un impacto social positivo. De esta manera, el balance global de la REC es positivo ya que ha permitido el desarrollo de la UCLV sin incrementar los impactos ambientales, por lo que se puede considerar un paso en el camino hacia la sostenibilidad socio-ambiental.

La crisis del drama en la contemporaneidad: Attempts on her life de Martin Crimp

Attempts on her life es una obra que desafía la posibilidad de su propia representación. El tratamiento del personaje; la ausencia de diálogo strictu sensu; una acción que se desarrolla en el relato de los locutores; espacio y tiempo que no acaban de definirse sino en el hic et nunc del espectáculo: todo esto convierte la obra de Crimp en parámetro ideal para detectar el estado de la llamada crisis del drama en la contemporaneidad. Este trabajo quiere centrarse en la relevancia que las características formales y de contenido de la obra cobran dentro del ámbito dramatúrgico y filosófico contemporáneos

“Identidad en crisis y estética de la fragmentariedad en la novela de Roberto Bolaño”

Este trabajo analiza las formas que adopta la crisis de la identidad, elemento esencial de la literatura posmoderna, en las principales novelas de Roberto Bolaño (La literatura nazi en América, Estrella distante, Los detectives salvajes, Amuleto, Nocturno de Chile y 2666), tanto a nivel temático como estructural. Dicha crisis se convierte en el eje vertebrador de motivos como el doble, el viaje o la locura, y de una concepción novelística que cuestiona sus propios mecanismos, dando lugar a una “estética de la fragmentariedad”, a relatos polifónicos y múltiples que a partir de las simetrías se integran en una estructura globalizadora.
