Spillover effect of environmental investment: evidence from panel data at provincial level in China

This paper considers pollution density as a function of environmental investment. The higher environmental investment, the lower pollution density. The lower the pollution density is the higher production technology becomes. This is called the spillover effect. We collected China's panel data at the provincial level from 2005 to 2009, and tested the spillover effect of environmental investment. This paper finds that the environmental investment influenced production technology positively. There is a significant positive relation between government expenditure and spillover effect.

Wildlife and coal development: An overview

This paper briefly reviews the changes which have occurred in the past three hundred years in the public's attitudes toward our Nation's natural resources, particularly the wildlife resources. It discusses how these changing attitudes have contributed to today's surface coal mine reclamation laws which require that the disturbed land be restored to a level of productivity equal to or greater than that which occurred before mining. This paper stresses the need to manage each reclamation site on an ecosystem basis, recognizing the interrelationships of all the resource components. This paper emphasizes both the fundamental importance of the holistic approach to mine site reclamation and the responsibility that the wildlife biologist has to see to it that wildlife habitat considerations are incorporated into each phase of the reclamation plan. Brief management considerations are given to three unique reclamation habitat types; riparian, agriculture and forest.

The effectiveness of cluster approach to improve environmental corporate performance in an industrial district of SMEs: a case study

This paper aims to assess the effectiveness of the so-called ‘Eco-Management and Audit Scheme (EMAS) cluster approach’ when applied to environmental policies, by focusing on the case history of the industrial paper production cluster located in the Province of Lucca (Italy). The Lucca cluster represents approximately 20% of Italian paper production, and Italy is the fourth leading paper producer in Europe. In the last 10 years, environmental policies have been developed under the common ‘umbrella’ of a strong public and private partnership based on stakeholder networking within the application of the EU EMAS Regulation. This article evaluates the outcome of such an approach, by comparing the environmental performance indicators for the Lucca’s paper industry using data collected from more than 40 plants before and after the adoption of this voluntary tool. The results show considerable improvements for many environmental performance indicators, consistently with the implementation of the cluster approach.     

Exhaustible Resource Allocation in an Overlapping Generations Economy

This paper analyzes competitive allocations of an exhaustible resource in an overlapping generations economy. Conditions are given for the existence of equilibrium extraction rules such that both extraction and investment in future stocks are increasing and continuous in the current stock. The paper then considers the time paths of equilibrium allocations and shows that there are economies where equilibrium resource extractions and prices exhibit nonclassical behavior. This is illustrated through a finite horizon example in which extractions increase and prices decrease over the entire time horizon and an infinite horizon example where there are persistent cycles in extractions and prices and multiple equilibria. The paper concludes by examining welfare issues.     

The implementation of environmental education to promote sustainability: an overview of the processes and challenges

ABSTRACT

This paper interprets aspects of the implementation of environmental education in a Higher Education Institution, situated in a developing country, to promote Education for Sustainable Development (ESD). The paper will allow educators to categorise the multiplicity of ESD programmes and projects in higher education institutions, determine their limitations and acceptability, and benefit from the theoretical framework of affective learning in designing new ESD interventions. The paper will also provide an overview of the processes required to establish ESD in developing and developed countries. This paper will further help universities to develop a better understanding of how integration of the three components of sustainable development – economic development, social development and environmental protection – can be incorporated in higher education. The paper explores the challenges for planning the implementation of ESD in an education faculty, outlining the potential lessons learned that could assist in improving ESD efforts in Faculties of Education.     

Jobs and climate policy: Evidence from British Columbia's revenue-neutral carbon tax

This paper examines the employment impact of British Columbia's revenue-neutral carbon tax implemented in 2008. While all industries appear to benefit from the redistributed tax revenues, the most carbon-intensive and trade-sensitive industries see employment fall with the tax, while clean service industries see employment rise. By aggregating across industries I find the BC carbon tax generated, on average, a small but statistically significant 0.74 percent annual increases in employment over the 2007–2013 period. This paper provides initial evidence showing how a revenue-neutral carbon tax may not adversely affect employment.

纳米颗粒与生物来源有机磷在水环境中的行为研究

随着纳米技术产业的快速发展,各种纳米颗粒(NPs)大规模生产,这不可避免地增加了NPs释放到环境、暴露于生态系统的可能性.有机磷是废水中磷的主要形式之一,是生物有效磷池和水体富营养化的重要组成部分.本文综述了近几年来NPs与生物来源有机磷在水环境中的反应机制、微观结构等方面的研究进展.文中按NPs的分类分别总结了NPs对常见的生物来源有机磷的吸附-解吸,溶解-沉淀等反应特性和微观机制.在水环境中,NPs因其物化特性受水化学条件(pH、天然有机质、温度)等影响,进而影响与有机磷的反应,从而表现出相应不同的环境效应.本文也对此方面的研究进行了讨论和总结.最后分析了目前纳米颗粒与有机磷在水环境研究中的瓶颈问题,并展望了未来需要开展的研究.     

Disarming the population bomb

This paper argues for a renewed international focus on managed population reduction as a key enabler of sustainable development. The paper presents development data that demonstrate why population reduction should be elevated to share top priority with poverty alleviation, as the two over-arching goals of international development strategy. The critical analysis put forth in this paper argues that the current ‘unsustainable’ approach to sustainable development stems from (1) ‘empty world’ economic growth theory applied to a ‘full world’, which is (2) supported and driven by socioeconomic incentives to expand population, (3) justified through flawed interpretation of demographic transition theory, (4) bolstered by the exaggerated efficacy of environmental economic theory applied in a resource-constrained world, (5) insulated from challenge by limitations of scientific knowledge and (6) perpetuated by herd behavior. This paper concludes that failure to reduce global population will inhibit attainment of poverty alleviation and worsen environmental degradation.

Coastal landscape and the Greek spatial planning: evidence from windpower in the South Aegean islands

This paper discusses issues about the coastal and the insular landscape integration in the Greek spatial planning framework. Case study area is the region of the South Aegean, where the proliferation of wind turbines is one of the principal factors of landscape change. The methodological approach adopted is mainly quantitative and is based on viewshed analysis. This paper is also demonstrates that zones with varying impact on landscape can be identified. It also emerges that the spatial planning framework in Greece promotes an ad hoc project-led instead of a plan-based approach to coastal and insular landscape management.     

Organizational adoption of sustainable manufacturing practices in India: integrating institutional theory and corporate environmental responsibility

Organizations are increasingly engaging in socially and environmentally sustainable initiatives. This paper focuses on the institutional isomorphism mechanisms to analyse the organizational adoption of sustainable manufacturing practices like eco-design, source reduction, and environmental management practices. This paper empirically examines the role of institutional influence in the organizational adoption of sustainable manufacturing practices among firms in India. The results of this study confirm the significance of the three institutional isomorphism mechanisms in influencing sustainable responses, but not all mechanisms influence the organizational response equally. In particular, the results show a strong influence of self-regulatory normative isomorphism on the implementation.     

Mapping the intertidal vegetation of the harbours of southern England for water quality management

This paper discusses a research project dealing with the mapping of the intertidal vegetation of several harbours along the southern coastline of England. It describes in detail the methods used to map the vegetation and gives examples of the results from these studies. This paper then goes on to explain how these results are applied by the Environment Agency of England and Wales to improve water quality in the harbours. This type of vegetation mapping is useful in monitoring the development of the intertidal species includingSpartina, Zostera and of particular importance to this study the green algaeUlva andEnteromorpha. The work was undertaken with funding from the Environment Agency and at present has taken place over a four year period. The data collected will be used by the Environment Agency to assess macro-algae covervalues for the intertidal area of the harbours concerned. This forms part of the Agency's commitment to the EU Nitrates Directive and the Urban Waste Water Treatment Directive. Some of the species mapped act as suitable indicators of water quality and are symptoms of entrophication. Other species are of interest for nature conservation and were recorded to provide a record for longer-term trends in vegetation patterns within the harbour. This paper aims to provide readers with an understanding of the techniques involved as well as an evaluation of the methodology.

Regulator reputation, enforcement, and environmental compliance

This paper explores empirically the impact of enforcement efforts on environmental compliance, focusing on the role of regulator reputation spillover effects. We find that, on the margin, the impact of a fine for water pollutant violations is about a two-thirds reduction in the statewide violation rate in the year following a fine. This large result obtains through the regulator's enhanced reputation; the deterrence impact on other plants in a state is almost as strong as the impact on the sanctioned plant. Focusing only on the response of the sanctioned plant, as in previous studies, may therefore seriously underestimate the efficacy of fines and other sanctions. This paper also examines the relative effectiveness of monitoring and enforcement instruments. Non-monetary sanctions contribute no detected impact on compliance, and the marginal fine induces substantially greater compliance than the marginal inspection.
