We examine cost and nutrient use efficiency of farms and determine the cost to move farms to nutrient-efficient operation using Data Envelopment Analysis (DEA) with a dataset of 96 rice farms in Gangwon province of South Korea from 2003 to 2007. Our findings show that improvements in technical efficiency would result in both lower production costs and better environmental performance. It is, however, not costless for farms to move from their current operation to the environmentally efficient operation. On average, this movement would increase production costs by 119% but benefit the water system through an approximately 69% reduction in eutrofying power (EP). The average estimated cost of each EP kg of aggregate nutrient reduction is approximately one thousand two hundred won. For technically efficient farms, there is a trade-off between cost and environmental efficiency. We also find that the environmental performance of farms varies across farms and regions. We suggest that agri-environmental policies should be (re)designed to improve both cost and environmental performance of rice farms.

Environmental Management has become one of the most used terms in recent times. But, what exactly does the term mean and entail? Environmental management helps to investigate and manage the environment within the context of human influences, incorporating an examination of economics, culture, political structure, and social equity, as well as natural processes and systems. This book discusses in detail the various issues relating to environmental management, including the fundamentals; the various environmental policies, legislations and international treaties; the concept of environmental impact assessment; environmental auditing; life cycle assessment; various environmental management system standards; issues and techniques, and environmental design and economics has become one of the most used terms in recent times.

Evaluating environmental policies, such as the mitigation of greenhouse gases, frequently requires balancing near-term mitigation costs against long-term environmental benefits. Conventional approaches to valuing such investments hold interest rates constant, but the authors contend that there is a real degree of uncertainty in future interest rates. This leads to a higher valuation of future benefits relative to conventional methods that ignore interest rate uncertainty.

Market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies. These combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology. Both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives, and can be cost-effectively harnessed through the use of economic-incentive based policy. In the presence of weak or nonexistent environmental policies, investments in the development and diffusion of new environmentally beneficial technologies are very likely to be less than would be socially desirable. Positive knowledge and adoption spillovers and information problems can further weaken innovation incentives. While environmental technology policy is fraught with difficulties, a long-term view suggests a strategy of experimenting with policy approaches and systematically evaluating their success. © 2005 Elsevier B.V.

Background: This study aimed to investigate relationships between environmental aesthetics, convenience, and walking companions and walking for exercise or recreation and to investigate differences in these relationships by sex and by reported physical and mental health.

Methods: Analyses of cross-sectional self-report data from a statewide population survey of 3,392 Australian adults were used.

Results: Men and women reporting a less aesthetically pleasing or less convenient environment were less likely to report walking for exercise or recreation in the past 2 weeks. Those respondents, particularly women, reporting no company or pet to walk with were also less likely to walk for exercise or recreation. Associations with environmental and social influences were observed for men and women reporting both good and poor physical and mental health.

Conclusions: Perceived environmental aesthetics and convenience and walking companions are important correlates of walking for exercise among urban Australians. Acknowledging the cross-sectional nature of these data, findings support a case for evaluation of environmental policies to promote physical activity.

Issue addressed: Health programs have been part of the responsibility of Victorian school education for 90 years. Yet rarely have there been studies to identify what is happening in school health promotion, or what the differences between schools might be, particularly in relation to the socioeconomic status of the school community and whether the school is in a metropolitan or regional area. Methods: In 1997 all Victorian schools (primary and secondary) in the State, Catholic and Independent systems were sent questionnaires in order to promote broader awareness about health promotion, and to identify what health programs, policies and activities the schools believed existed within their school community. A response rate of 43% was achieved, and results were collated under the six domains of the Health Promoting School model as outlined by the Western Pacific Regional Office of the World Health Organisation. Data analysed in this paper compared highest versus lowest quartiles for socioeconomic status (SES), and schools in metropolitan Melbourne versus regional areas. Results: Most differences between schools based on socioeconomic status occurred in secondary schools and were related mainly to environmental policies and practices, use of back packs, the presence of safety policies, involvement of parents in school activities and the provision of services for mental and social health needs. All differences were in favour of the highest SES quartile schools. Environmental policies and procedures, and school-based health and welfare services were present more often in metropolitan schools than in regional and rural schools. Conclusion: Although there were notable differences between schools, the audit results pointed to more similarities than differences between schools in the highest and lowest SES quartiles for health-related policies and practices; there were even fewer differences between metropolitan and non-metropolitan schools. So what: Regardless of the actual advantages and disadvantages schools experience with respect to location or socioeconomic status, it is important to understand that school staff perceive that they can and do have reasonably comprehensive health policies, procedures and practices to address health issues. Nevertheless, clear differences between schools did emerge in certain health areas and findings will assist policy making and the allocation of limited resources.

This thesis contends that government focus on policy implicitly defines community education as a means of overcoming barriers to government-initiated change, rather than as an input to governmental decision-making. The role of education is thus viewed as instrumentalist rather than as dialectical in nature. I argue that this role has been reinforced and driven by economic rationalism, as a mechanism related to scientific theory and practice. The thesis addresses the role of government in non-institutional community-based environmental education. Of interest is environmental education under the dominance of economic rationalism and as expressed in government-derived policy, in its own right, and as enacted in two government funded animal management projects. The main body of data, then, includes a review of some contemporary environmental policies and two case studies of 'policy in practice'. Chapter One provides an overview of environmentalism as it has emerged as part of the discourse of Western political systems. Recognised as part of this change is a move to environmentalism embued with the rhetoric of economic theory. The manifestation of this change can be seen in an emphasis on management for the natural environment's use as a resource for humans. Education under this arrangement is valued in terms of its ability to support initiatives that are perceived as economically viable and economically advantageous, maintaining centralised control of decision-making and serving the interests of those who profit from this arrangement. Government-derived environmental policies are presented in Chapter Two. They provide evidence of the conjoining of environment with economic rationalism and the adoption of a particular stance which is both utilitarian and instrumentalist. Emerging from this is an understanding of the limitations placed on environmental debates that do not respond to complex understandings of context and instead support and legitimate centralisation of decision-making and control. Chapter Three presents an argument for an historical approach to environmental education research to accommodate contextual dimensions, as well as scientific, economic and technical dimensions, of the subject under study. An historical approach to research, inclusive of biographical, intergenerational and geographical histories, goes some way to providing an understanding of current individual and collective responses to policy enactment within the two study sites. It also responds to the concealing of history which results from the reduction of environmental debates to economic terms. With this in mind, Chapters Four and Five provide two historical case studies of 'policy in practice'. Chapter Four traces the workings of a rabbit control project in the Sutton Grange district of Victoria and Chapter Five provides an account of a mouse plague project in the Wimmera and Mallee regions of Victoria. The Sutton Grange rabbit project is organised and controlled by district landholders while the Wimmera and Mallee mouse project is organised and controlled by representatives from a scientific organisation and a government agency. Considered in juxtaposition, the two case studies enable an analysis of two somewhat different expressions of the 'role of government'. Chapter Six investigates the competing processes of community participation in governmental decision-making and Australia's system of representative democracy, Despite a call for increased community participation, the majority of policies remain dominated by governmental rhetoric and ideology underpinned by a belief in impartiality. The primacy of economics is considered in terms of government and community interaction, with specific reference to the emergence of particular conceptual constructions, such as cost-benefit analysis, that support this dominance. Of specific importance to this thesis is the argument that economic theory is essentially anthropocentric and individualist and, thus, necessarily marginalises particular conceptions of environment that are non-anthropocentric and non-individualistic. Finally, Chapter Six examines two major interrelated tensions; those of central interests and community interests, and economic rationalism and environmentalist. Chapter Seven looks at examples of theories and practices that fall outside the rationality determined by scientistic knowledge. It is clear from the examination of environmental policy within this thesis that the role ascribed to environmental education is instrumentalist. The function of education is often to support, promote and implement policy and its advocated practices. It is also clear from the examination of policy and advocated processes that policy defines community education as a means of manifesting change as determined by policy, rather than as an input to governmental decision-making. The domination of scientific, economic and technocratic processes (and legitimation of processes) allows only for an instrumentalist approach to education from government. What is encouraged by government through the process of change is continuity rather than reform. It promotes change that will not disrupt the governing hegemony. Particular perspectives and practices, such as a critical approach to education, are omitted or considered only within the unquestioned rationale of the dominant worldview. Chapter Seven focuses on the consequence of government attention to policy which implicitly defines community education as a means of overcoming barriers to change, rather than as an input to governmental decision-making. Finally a list of recommendations is put forward as a starting point to reconstruct community-based environmental education. The role considered is one that responds to, and encourages engagement in, debates which expose disparate views, assumptions and positions. Community ideology must be challenged through the public practices of communication and understanding, decision-making, and action. Intervention is not on a level that encourages a preordinate outcome but, rather, what is encouraged is elaborate consideration of disparate views and rational opinions, and the exposure of assumptions and interests behind ideological positions.

In this study we analysed the familiarity and understanding of 10 environmental concepts amongst Mexican and English school children (aged 7 to 9). The investigation considered the impact of the educational system and the school ethos on the formation of environmental concepts. Results reveal that in general, children of this age have a low to moderate level of environmental literacy. The educational system and pedagogical approach affect the way children learn environmental concepts. Schools with a strong orientation towards the environment seem more capable of helping children with their understanding of environmental concepts. School and television were the major sources of environmental information, but this varied with school ethos. The development of effective environmental policies in schools needs to be considered in order to promote environmental knowledge in the school population.

Culture and spirit of land is integral to Indigenous community meaning and identity. With colonisation, transmigration and assimilation policies and practices over the last 200 years, many Indigenous communities, like the Minahasa, have witnessed their culture, curatorial responsibilities, and their mythological associations to their lands eroded. Minahasa, meaning 'becoming one united', encompasses some eight ethnic communities who reside in the Minahasa regencies in the North Sulawesi Province on Sulawesi Island in Indonesia. The region was first colonised by the Portuguese in the 16th century, and then by the Dutch VOC (Verenigde Oostindische Compagnie) in the 17th and 18th centuries bringing a strong Christian Protestant faith to the communities that appropriated many of the cultural symbols and mythological narratives of the Minahasa, and now compromises the largest concentration of Christian faith in the Indonesian archipelago being one of the reasons why there was considerable political requests for the region to formally become a province of The Netherlands in the lead up to Indonesian independence in 1945.

North Sulawesi never developed any large empire like on other islands in the archipelago. In 670, the leaders of the different tribes, who all spoke different languages, met by a stone known as Watu Pinawetengan. There they founded a community of independent states, who would form one unit and stay together and would fight any outside enemies if they were attacked, and the Dutch used this cultural ethos to help unite the linguistically diverse Minahasa confederacy under their colonial regime. Integral to the Minahasa is the Watu Pinawetengan and the series of narratives that enjoin the Minahasan communities to this place and around Lake Tondano. With Indonesian governance considerable angst has been launched by the Minahasa about loss of local autonomy, generic Indonesian policies, and a lack of respect of Indigenous culture and non-mainstream religions within this predominantly Moslem nation. This paper reviews the state of knowledge as to the cultural associations and genius loci meanings of the Minahasa, to their landscape and place, cast against contemporary Indonesian 10 year plans and policies that seek to generically manage the collective Indonesian archipelago as one community and landscape. It is a critique about the Minahasan Indigenous land use and planning philosophies, against top-down generic land use and environmental policies and plans written in Jakarta for generic application across the Indonesian archipelago.

The idea of sustainable development is distinct from the idea of restoring or conserving nature. This concept is embedded in the Rio Declaration on Environment and Development (1992) which Indonesia and several countries around the world have signed. Sustainable development seeks to interlace humans and nature, while restoration (especially at the large scale) often allows nature to be addressed separately, sometimes out of remorse for the damage caused by humans. In terms of attaining sustainable natural resource development, the opportunities offered by traditional ecological knowledge documentation are considered essential in enabling the achievement of sustainability because most of these Indigenous and/or local communities are situated in areas where many species have been historically cultivated and used in a sustainable way for thousands of years. The skill and techniques of these local communities can provide valuable information for the global community to evaluate current environmental policies. Such research and evaluation is often robustly and best undertaken through ethnoecological methodological paradigms. This paper examines the traditional environment knowledge of the Minahasan ethnic community, who live in the surrounds of Lake Tondano in the North Sulawesi, together with the Minahasan conscious and unconscious actions in conserving their forest ecology in addition to their knowledge of culture about forest protection in the region. In particular, contemporary use of traditional environmental knowledge is examined in terms of its relevance to in traditional resource management and land use planning, as avenues to better curate and manage natural resources through informed regional planning strategies and mechanisms.

This thesis aims to fill the gap in the literature by examining the relationship between technological trajectories and environmental policy in the automotive industry, focusing on the role of environmental policies in unlocking the industry from fossil fuel path-dependence. It first explores the inducement mechanism that underpins the interaction between environmental policy and green technological advances, investigating under what conditions the European environmental transport policy portfolio and the intrinsic characteristics of assignees' knowledge boost worldwide green patent production. Subsequently, the thesis empirically analyses the dynamics of technological knowledge involved in technological trajectories assessing evolution patterns such as variation, selection and retention, in order to study the impact of policy implementation on technological knowledge related to electric and hybrid vehicle technologies. Finally, the thesis sheds light on the drivers that encourage a shift from incumbent internal combustion engine technologies towards low-emission vehicle technologies. This analysis tests whether tax-inclusive fuel prices and technological proximity between technological fields induce a shift from non-environmental inventions to environmentally friendly inventive activities and if they impact the competition between alternative vehicle technologies. The findings provide insights into the effectiveness of environmental policy in triggering inventive activities related to the development of alternative vehicle technologies. In addition, there is evidence that environmental policy redirects technological efforts towards a sustainable path and impacts the competition between low-emission vehicles.

This paper analyzes the development of environmental concern by using the three waves of the environmental modules of the International Social Survey Programme (ISSP). First, we discuss the measurement of environmental concern and construct a ranking of countries according to the new 2010 ISSP results. Second, we analyze the determinants of environmental concern by employing multilevel models that take individual as well as context effects into account. Third, we explore the impact of attitudes on environmental behavior and support of environmental policies. The results show that environmental concern is closely correlated with the wealth of nations. However, environmental concern decreased in OECD as well as non-OECD nations slightly during the last two decades. The decline was lower in countries with improving economic conditions suggesting that economic growth helps to maintain higher levels of environmental concern. Furthermore, attitudes have a stronger impact on support of environmental policies as compared to everyday environmental behavior.

This paper sheds new light on the determination of environmental policies in majoritarian federal electoral systems such as the U.S., and derives implications for the environmental federalism debate on whether the national or local government should have authority over environmental policies. In majoritarian systems, where the legislature consists of geographically distinct electoral districts, the majority party (at either the national or the state level) favors its own home districts; depending on the location of polluting industries and the associated pollution damages, the majority party may therefore impose sub-optimally high or low pollution taxes due to a majority bias. We show that majority bias can influence the social-welfare ranking of alternative government policies and, in some cases, may actually bring distortionary policies closer to the first-best solution.

Esta Tesis surgió ante la intensidad y verosimilitud de varias señales o “warnings” asociadas a políticas dirigidas a reducir el peso del petróleo en el sector energético, tanto por razones económicas, como geopolíticas, como ambientales. Como tal Tesis se consolidó al ir incorporando elementos novedosos pero esenciales en el mundo petrolífero, particularmente las “tecnologías habilitantes”, tanto de incidencia directa, como el “fracking” como indirecta, del cual es un gran ejemplo el Vehículo Eléctrico (puro). La Tesis se definió y estructuró para elaborar una serie de indagaciones y disquisiciones, que comportaran un conjunto de conclusiones que fueran útiles para las corporaciones energéticas. También para la comprensión de la propia evolución del sector y de sus prestaciones técnicas y económicas, de cara a dar el servicio que los usuarios finales piden. Dentro de las tareas analíticas y reflexivas de la Tesis, se acuñaron ciertos términos conceptuales para explicar más certeramente la realidad del sector, y tal es el caso del “Investment burden”, que pondera la inversión específica (€/W) requerida por una instalación, con la duración del período de construcción y los riesgos tanto tangibles como regulatorios. Junto a ello la Tesis propone una herramienta de estudio y prognosis, denominada “Market integrated energy efficiency”, especialmente aplicable a dicotomías. Tal es el caso del coche térmico, versus coche eléctrico. El objetivo es optimizar una determinada actividad energética, o la productividad total del sector. Esta Tesis propone varias innovaciones, que se pueden agrupar en dos niveles: el primero dentro del campo de la Energía, y el segundo dentro del campo de las corporaciones, y de manera especial de las corporaciones del sector hidrocarburos. A nivel corporativo, la adaptación a la nueva realidad será función directa de la capacidad de cada corporación para desarrollar y/o comprar las tecnologías que permitan mantener o aumentar cuota de mercado. Las conclusiones de la Tesis apuntan a tres opciones principalmente para un replanteamiento corporativo: - Diversificación energética - Desplazamiento geográfico - Beneficiándose de posibles nuevos nichos tecnológicos, como son: • En upstream: Recuperación estimulada de petróleo mediante uso de energías renovables • En downstream: Aditivos orientados a reducir emisiones • En gestión del cambio: Almacenamiento energético con fines operativos Algunas políticas energéticas siguen la tendencia de crecimiento cero de algunos países de la OCDE. No obstante, la realidad mundial es muy diferente a la de esos países. Por ejemplo, según diversas estimaciones (basadas en bancos de datos solventes, referenciados en la Tesis) el número de vehículos aumentará desde aproximadamente mil millones en la actualidad hasta el doble en 2035; mientras que la producción de petróleo sólo aumentará de 95 a 145 millones de barriles al día. Un aumento del 50% frente a un aumento del 100%. Esto generará un curioso desajuste, que se empezará a sentir en unos pocos años. Las empresas y corporaciones del sector hidrocarburos pueden perder el monopolio que atesoran actualmente en el sector transporte frente a todas las demás fuentes energéticas. Esa pérdida puede quedar compensada por una mejor gestión de todas sus capacidades y una participación más integrada en el mundo de la energía, buscando sinergias donde hasta ahora no había sino distanciamiento. Los productos petrolíferos pueden alimentar cualquier tipo de maquina térmica, como las turbinas Brayton, o alimentar reformadores para la producción masiva de H2 para su posterior uso en pilas combustible. El almacenamiento de productos derivados del petróleo no es ningún reto ni plantea problema alguno; y sin embargo este almacenamiento es la llave para resolver muchos problemas. Es posible que el comercio de petróleo se haga menos volátil debido a los efectos asociados al almacenamiento; pero lo que es seguro es que la eficiencia energética de los usos de ese petróleo será más elevada. La Tesis partía de ciertas amenazas sobre el futuro del petróleo, pero tras el análisis realizado se puede vislumbrar un futuro prometedor en la fusión de políticas medioambientales coercitivas y las nuevas tecnologías emergentes del actual portafolio de oportunidades técnicas. ABSTRACT This Thesis rises from the force and the credibility of a number of warning signs linked to policies aimed at reducing the role of petroleum in the energy industry due to economical, geopolitical and environmental drives. As such Thesis, it grew up based on aggregating new but essentials elements into the petroleum sector. This is the case of “enabling technologies” that have a direct impact on the petroleum industry (such as fracking), or an indirect but deep impact (such as the full electrical vehicle). The Thesis was defined and structured in such a way that could convey useful conclusions for energy corporations through a series of inquiries and treatises. In addition to this, the Thesis also aims at understating la evolution of the energy industry and its capabilities both technical and economical, towards delivering the services required by end users. Within the analytical task performed in the Thesis, new terms were coined. They depict concepts that aid at explaining the facts of the energy industry. This is the case for “Investment burden”, it weights the specific capital investment (€/W) required to build a facility with the time that takes to build it, as well as other tangible risks as those posed by regulation. In addition to this, the Thesis puts forward an application designed for reviewing and predicting: the so called “Market integrated energy efficiency”, especially well-suited for dichotomies, very appealing for the case of the thermal car versus the electric car. The aim is to optimize energy related activity; or even the overall productivity of the system. The innovations proposed in this Thesis can be classified in two tiers. Tier one, within the energy sector; and tier two, related to Energy Corporation in general, but with oil and gas corporations at heart. From a corporate level, the adaptation to new energy era will be linked with the corporation capability to develop or acquire those technologies that will yield to retaining or enhancing market share. The Thesis highlights three options for corporate evolution: - diversification within Energy - geographic displacement - profiting new technologies relevant to important niches of work for the future, as: o Upstream: enhanced oil recovery using renewable energy sources (for upstream companies in the petroleum business) o Downstream: additives for reducing combustion emissions o Management of Change: operational energy storage Some energy policies tend to follow the zero-growth of some OECD countries, but the real thing could be very different. For instance, and according to estimates the number of vehicles in use will grow from 1 billion to more than double this figure 2035; but oil production will only grow from 95 million barrel/day to 145 (a 50% rise of versus an intensification of over a 100%). Hydrocarbon Corporation can lose the monopoly they currently hold over the supply of energy to transportation. This lose can be mitigated through an enhanced used of their capabilities and a higher degree of integration in the world of energy, exploring for synergies in those places were gaps were present. Petroleum products can be used to feed any type of thermal machine, as Brayton turbines, or steam reformers to produce H2 to be exploited in fuel cells. Storing petroleum products does not present any problem, but very many problems can be solved with them. Petroleum trading will likely be less volatile because of the smoothing effects of distributed storage, and indeed the efficiency in petroleum consumption will be much higher. The Thesis kicked off with a menace on the future of petroleum. However, at the end of the analysis, a bright future can be foreseen in the merging between highly demanding environmental policies and the relevant technologies of the currently emerging technical portfolio.
