Influencia social y sostenibilidad en el uso de recursos renovables 31
Almudi, Isabel; Choliz, Julio Sanchez.
En este trabajo presentamos un modelo en el que las actividades extractivas referidas a un recurso natural renovable, si son abusivas, generan algún tipo de reacción social que modifica las preferencias sociales. Esta modificación es tenida en cuenta por el planificador a la hora de decidir cual es la asignación intertemporal óptima entre consumo y stock del recurso. Bajo estas nuevas condiciones, nos preguntamos cómo cambia el stock del recurso natural en el estado estacionario y qué puede decirse acerca de la posibilidad de sobreexplotación en comparación con los modelos tradicionales en los que no se considera reacción social. Los resultados obtenidos muestran que bajo estas nuevas condiciones el stock del estado estacionario aumenta y el comportamiento...

El control de la contaminacion por nitratos en el regadio 31
Martinez, Yolanda Martinez; Karaj, Skender Uku; Murillo, Jose Albiac.
RESUMEN: En este artículo se analizan los efectos de algunas políticas de gestión del agua y de las técnicas de riego sobre el rendimiento de las actividades de cultivo y la contaminación del agua en la zona de regadío de Flumen-Monegros. El análisis se basa en la obtención de la respuesta del rendimiento de los cultivos al agua de riego y al abonado de nitrógeno. Las funciones de rendimiento se estiman mediante el programa de crecimiento de cultivos EPIC que incorpora información de las características locales de clima, suelo, manejo y sistema de riego de las actividades de cultivo. En los resultados se examina la relación entre los rendimientos y el uso del agua y del nitrógeno, y se cuantifica el coste para los agricultores de la reducción de la...

Changing the direction of environmental investment in Australia: Learnings from implementing INFFER 31
Marsh, Sally P.; Curatolo, April; Pannell, David J.; Park, Geoff; Roberts, Anna M.; Alexander, Jennifer.
Investment in natural resource management (NRM) by regional organisations in Australia has been widely criticised for failing to achieve substantial environmental outcomes. The Investment Framework for Environmental Resources (INFFER) is a tool for developing and prioritising projects to address environmental issues such as water quality, biodiversity decline, environmental pest impacts and land degradation. INFFER is an asset-based, targeted, and outcome-focussed approach to environmental investment, and as such is a very different and more rigorous approach to prioritising possible environmental projects than used previously by most catchment management organisations (CMOs) in Australia. From 2008 to 2010 INFFER has been trialled with CMOs. Evaluation...

Technology Diffusion, Abatement Cost, and Transboundary Pollution 31
Heal, Geoffrey; Tarui, Nori.
This paper studies countries’ incentives to develop advanced pollution abatement technology when technology may spillover across countries and pollution abatement is a global public good. We are motivated in part by the problem of global warming: a solution to this involves providing a global public good, and will surely require the development and implementation of new technologies. We show that at the Nash equilibrium of a simultaneous-move game with R&D investment and emission abatement, whether the free rider effect prevails and under-investment and excess emissions occur depends on the degree of technology spillovers and the effect of R&D on the marginal abatement costs. There are cases in which, contrary to conventional wisdom, Nash...

Residential Water Consumption: A Cross Country Analysis 31
Grafton, R. Quentin; Kompas, Tom; To, Hang; Ward, Michael B..
Survey data from over 1,600 households in ten countries were used to analyse the determinants of residential water demand. Results show that in every country the price elasticity is negative and statistically significant. Households that do not have to pay for the water they use (volumetric water charges) consume about a third more water than similar households that do have to pay such charges. Consumers’ attitudes do not have a statistically significant effect on total water use, although they do increase the probability of households using some water saving behaviours. Volumetric water charges also have an impact on the adoption of water saving actions. Full-cost water pricing appears to be a highly effective instrument to manage residential water...

U.S. State-Level Carbon Dioxide Emissions: A Spatial-Temporal Econometric Approach of the Environmental Kuznets Curve 31
Burnett, J. Wesley; Bergstrom, John C..
One of the major criticisms of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored. By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected by events in neighboring regions (i.e., assume there are no transboundary pollution emissions between neighbors). By ignoring the spatial aspects within the data several past estimates of the EKC could have generated biased or inconsistent regression results. By ignoring the temporal aspect within the data several past estimates of the EKC could have generated spurious regression results or misspecified t and F statistics. To address this potential...

The Economics of Wind Power with Energy Storage 31
Benitez, Pablo C.; Dragulescu, Lilianna; van Kooten, G. Cornelis.
We develop a nonlinear mathematical optimization program for investigating the economic and environmental implications of wind penetration in electrical grids and evaluating how hydropower storage could be used to offset wind power intermittence. When wind power is added to an electrical grid consisting of thermal and hydropower plants, it increases system variability and results in a need for additional peak-load, gas-fired generators. Our empirical application using load data for Alberta’s electrical grid shows that 32% wind penetration (normalized to peak demand) results in a net cost increase of $C5.20/ MWh, while 64% wind penetration could result in an increase of $12.50/MWh. Costs of reducing CO2 emissions are estimated to be $41-$56 per t CO2 . When...

Modeling the Effects of Cap and Trade and a Carbon Offset Policy on Crop Allocations and Farm Income 31
Nalley, Lawton Lanier; Popp, Michael P..
A static, producer profit maximization framework is used to capture county level land use choice on the basis of profitability, greenhouse gas (GHG) emissions to the farm gate as well as soil carbon sequestration as affected by tillage and soil type. Policy scenarios of a 5% GHG cap on agricultural emissions in conjunction with a carbon offset payment system, designed to provide producer payments for net carbon footprint (GHG emissions – soil carbon sequestration) reductions compared to a baseline are evaluated to determine potential changes to land use and or producer income as a result of different policy scenarios. Results suggest that a policy solely targeted at emissions can be counterproductive in the sense that acreage reductions of more...

Análisis económico de la “bio-carbonización” como práctica de manejo agrícola 31
Ramirez, Juan Andres; Rosales Alvarez, Ramon.
Las altas concentraciones de gases de efecto invernadero, específicamente CO2, han sido señaladas como la principal causa del cambio climático. La adopción de prácticas agrícolas capaces de incrementar el contenido de carbono en el suelo, ha sido propuesta como una estrategia de bajo costo y disponibilidad inmediata para enfrentar este fenómeno. La Bio-carbonización es una de estas prácticas agrícolas, la cual implica la aplicación de carbón vegetal al suelo, de modo que el carbono queda capturado en una forma altamente recalcitrante al tiempo que se mejora la calidad del suelo. Este artículo es el primero en evaluar la viabilidad financiera y considerar algunos de los efectos económicos de la práctica, estimados para una finca tipo en la altillanura...

Economics of Natural Resource Scarcity: The State of the Debate 31
Krautkraemer, Jeffrey A..
Whether economic growth can be sustained in a finite natural world is one of the earliest and most enduring questions in economic literature. Even with unprecedented growth in human population and resource consumption, humans have been quite adept at finding solutions to the problem of scarce natural resources, particularly in response to signals of increased scarcity. Because environmental resources generally are not generally traded on markets, however, scarcity signals for these resources may be inadequate, and appropriate policy responses are difficult to implement and manage. In the debate over the economic scarcity of natural resources, one significant change in recent years has been a greater focus on the ecosystem services and the resource...

Consumer Preferences for Refrigerators Manufactured by “Climate Leaders” 31
Li, Xiaogu; Clark, Christopher D.; Jensen, Kimberly L.; Yen, Steven T..
In 2002, EPA established a voluntary program called the Climate Leaders Program (CL Program) designed for organizations to complete a corporate greenhouse gas (GHG) inventory, set a goal for reducing GHG emissions, and achieve that goal. The program was never implemented as a product labeling program. In 2010, EPA announced the program’s phase out. This study examines whether the CL Program could have been effectively used as a consumer product labeling program to assist consumers in choosing products manufactured by firms that have voluntarily set and achieved targeted GHG emission reductions.

The Potential for Wind Energy Meeting Electricity Needs on Vancouver Island 31
Prescott, Ryan; van Kooten, G. Cornelis; Zhu, Hui.
In this paper, an in-depth analysis of power supply and demand on Vancouver Island is used to provide information about the optimal allocation of power across ‘generating’ sources and to investigate the economics of wind generation and penetrability into the Island grid. The methodology developed can be extended to a region much larger than Vancouver Island. Results from the model indicate that Vancouver Island could experience blackouts in the near future unless greater name-plate capacity is developed. While wind-generated energy has the ability to contribute to the Island’s power needs, the problem with wind power is its intermittency. The results indicate that wind power may not be able to prevent shortfalls, regardless of the overall name-plate...

The Economic Valuation of Marine Ecosystems 31
Nunes, Paulo A.L.D.; Ding, Helen; Markandya, Anil.
In a democratic system, policy makers have to take the preferences of the citizens into account. Since we live in a world with scarce resources, one is asked to make choices regarding the use and management of these resources. In this context, if policy makers decide to invest in the protection of marine ecosystems, less financial resources will be available for other policy areas, for example national health. Moreover, the investment in the protection of marine ecosystems brings along with it the provision of a wide range of benefits to humans though most are not priced in the existing markets – for example climate regulation and provision of habitat for biodiversity. Given that most human activities are priced in one way or other, in some decision...

Using Auctions for Conservation Contracts to Protect Queensland's Vegetation: Lessons from the Vegetation Incentives Program 31
Comerford, Emma; Binney, Jim.
Auctions for conservation contracts are experiencing great popularity in Australia due to their perceived cost effectiveness. However, there is still much to be learned about this economic instrument. Queensland's state government recently decided to use an auction mechanism to allocate a $12 million incentives program. This was called the Queensland Vegetation Incentives Package (VIP), and was aimed at encouraging better protection and management of high value non-remnant vegetation. The PhD work of the presenting author is using the VIP as a case study to explore the use of auctions for conservation contracts in Queensland. In particular, observing the VIP gives insight into participant behaviour and the impact of the policy formation process on an...

A Multifunctional Comparison of Conventional versus Alternative Olive Systems in Spain by Using AHP 31
Parra-Lopez, Carlos; Calatrava-Requena, Javier.
Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

Efectos distributivos de las compensaciones por inactividad concedidas al sector pesquero afectado por la marea negra del Prestige 31
Castro, Daniel Fuentes.
Resumen En el presente trabajo se analizan las ayudas paliativas de primera hora destinadas a compensar la disminución de rentas derivada de la inactividad provocada por la marea negra del Prestige en el sector pesquero y marisquero gallego. En particular se analiza el diseño uniforme de dichas ayudas y sus efectos redistributivos entre los subsectores de actividad afectados. Asimismo se estima el coste total soportado por las administraciones públicas y se muestra cómo una sencilla re-evaluación de las ayudas hubiese permitido ajustar las compensaciones a la realidad económica de cada subsector de actividad afectado, corrigiendo de este modo la notable distorsión en la asignación de los recursos públicos. Keywords: Marea negra; Prestige; Compensaciones;...

Evaluacion comparativa multifuncional de sistemas agrarios mediante AHP: aplicacion al olivar ecologico, integrado y convencional en Andalucía 31
Lopez, Carlos Parra; Calatrava-Requena, Javier; Gimenez, Tomas De Haro.
Aunque el concepto de multifuncionalidad está plasmado, implícita o explícitamente, en el diseño de las políticas agrarias actuales, su consideración a la hora de analizar y evaluar sistemas agrarios es aún relativamente escasa en la literatura. Para tal fin se propone utilizar el Proceso Analítico Jerárquico (Analytic Hierarchy Process - AHP), técnica de decisión multicriterio discreta que se utiliza para la toma de decisiones complejas. La metodología AHP es expuesta junto con un procedimiento propuesto para medir el acuerdo relativo entre decisores y la uniformidad de las alternativas en la toma de decisiones en grupo. Finalmente, AHP es aplicado a la evaluación del olivar ecológico, integrado y convencional de Andalucía considerando criterios de...
