Environmental economic impact assessment in China: Problems and prospects

The use of economic valuation methods to assess environmental impacts of projects and policies has grown considerably in recent years. However, environmental valuation appears to have developed independently of regulations and practice of environmental impact assessment (EIA), despite its potential benefits to the EIA process. Environmental valuation may be useful in judging significance of impacts, determining mitigation level, comparing alternatives and generally enabling a more objective analysis of tradeoffs. In China, laws and regulations require the use of environmental valuation in EIA, but current practice lags far behind. This paper assesses the problems and prospects of introducing environmental valuation into the EIA process in China. We conduct four case studies of environmental economic impact assessment (EEIA), three of which are based on environmental impact statements of construction projects (a power plant, a wastewater treatment plant and a road construction project) and one for a regional pollution problem (wastewater irrigation). The paper demonstrates the potential usefulness of environmental valuation but also discusses several challenges to the introduction and wider use of EEIA, many of which are likely to be of relevance far beyond the Chinese context. The paper closes with suggesting some initial core elements of an EEIA guideline.     

Environmental impact assessment in Estonia and Norway

Authorities in Eastern European countries are looking for the best available policy tools from the West, and policy instruments tailored for a Western context are being introduced massively in the former state socialist countries of Europe. This study examines some of the contextual factors that hamper the introduction of modern, Western tools of environmental management within previously state socialist countries. These are highlighted through a comparison of how environmental impact assessment (EIA) is put into practice in Estonia and Norway. Estonia and Norway belong to the same European Baltic-Nordic region, but the two countries have a dramatically different history for most of this century.     

Large-scale renewable energy project barriers: Environmental impact assessment streamlining efforts in Japan and the EU

Environmental Impact Assessment (EIA) procedures have been identified as a major barrier to renewable energy (RE) development with regards to large-scale projects (LS-RE). However EIA laws have also been neglected by many decision-makers who have been underestimating its impact on RE development and the stifling potential they possess. As a consequence, apart from acknowledging the shortcomings of the systems currently in place, few governments momentarily have concrete plans to reform their EIA laws. By looking at recent EIA streamlining efforts in two industrialized regions that underwent major transformations in their energy sectors, this paper attempts to assess how such reform efforts can act as a means to support the balancing of environmental protection and climate change mitigation with socio-economic challenges. Thereby this paper fills this intellectual void by identifying the strengths and weaknesses of the Japanese EIA law by contrasting it with the recently revised EIA Directive of the European Union (EU). This enables the identification of the regulatory provisions that impact RE development the most and the determination of how structured EIA law reforms would affect domestic RE project development. The main focus lies on the evaluation of regulatory streamlining efforts in the Japanese and EU contexts through the application of a mixed-methods approach, consisting of in-depth literary and legal reviews, followed by a comparative analysis and a series of semi-structured interviews. Highlighting several legal inconsistencies in combination with the views of EIA professionals, academics and law- and policymakers, allowed for a more comprehensive assessment of what streamlining elements of the reformed EU EIA Directive and the proposed Japanese EIA framework modifications could either promote or stifle further RE deployment.     

Environmental impact assessment: National approaches and international needs

This paper examines the spread and development of ‘environmental impact assessment’ (EIA) since the enactment of the U.S. Environmental Policy Act on January 1, 1970, which established for the first time under any jurisdiction the formal requirement that an EIA be made and that an ‘environmental impact statement’ (EIS) be filed prior to implementation of certain major development projects. The paper is divided into three parts. In the first part, we briefly review the forms of EIA introduced in the western industrial countries and contrast these with developments in the socialist countries of Eastern Europe, and in the Third World. The approaches to EIA adopted by five countries — the United States, Australia, Canada, the Federal Republic of Germany, and the Soviet Union — are used to illustrate the types of national approaches that have been followed. In the second part of the paper, we use some questions raised by impact assessments as codified in legislation or regulations at the national level to highlight some of the limitations of impact assessment. Finally, we turn to international impact assessments and describe the modest progress made to date. Key impediments to the development of appropriate conceptual and institutional frameworks and methodologies for international EIAs are noted. In conclusion, we offer some suggestions about needed actions at both the national and international levels.     

Environmental impact assessment in the association of southeast Asian Nations

The Association of Southeast Asian Nations has agreed that environmental protection and sustainable use of natural resources are essential for sound economic development. The Environmental Impact Assessment is viewed as an important management tool and an ASEAN Experts Group on the Environment has been working for several years on a model especially adapted to the region and also on case studies of the implementation of EIA. Progress so far has been frustratingly slow due to misunderstanding, a lack of ecological data, inadequate trained manpower and institutional shortcomings for compliance. The author advocates collaboration on an ASEAN model for performing EIA as a means of accelerating acceptance and implementation. The concept of Adaptive Environmental Assessment and Management is proposed as a prototype.     

Health impact assessment of arsenic and cadmium intake via rice consumption in Bangkok,Thailand

Consumption of contaminated food is a major route of exposure to toxic contaminants for humans. To protect against potential negative health effects from rice consumption, As and Cd concentrations in rice sold in Bangkok were determined, and non-carcinogenic and carcinogenic risk assessments were conducted. Four types of rice (n = 97), namely, white jasmine, white, glutinous, and brown jasmine, were collected. Samples were acid-digested and analyzed for total concentrations of As and Cd by ICP-MS. The average concentrations of As and Cd were 0.205 ± 0.008 and 0.019 ± 0.001 mg kg^?1, respectively. Approximately 22.8, 62.5, and 57.1% of white, white jasmine, and brown jasmine rice, respectively, contained As concentrations exceeding the Codex inorganic As standards for polished and unpolished rice. Brown jasmine rice contained significantly higher As concentrations than the other types of rice. However, Cd concentrations in all rice samples were significantly lower than the Codex standard of 0.4 mg kg^?1. Children are exposed to the highest amounts of both elements. Concerning As exposure through the consumption of different types of rice in the same age group, the consumption of brown jasmine rice caused approximately 1.7 to 2.3 times higher As exposure rates compared to the consumption of other types of rice. Non-carcinogenic risks (hazard quotient (HQ)) of As exposure from all types of rice were higher than the threshold limit of 1. HQ in children ranging from 2.1 to 4.9 was significantly higher than HQ in the other age groups. The cancer risks from As exposure were negligible in all groups.

Environmental impact and adaptation study of pig farming relocation in China

Under the guidance of agri-food and water resources policies, some pig farms in China have gradually shifted their production from the Constrained Zone with a dense population and sensitive environment to the Potential Zone with richer feed resources and large environmental capacity. To evaluate whether the relocation is consistent with sustainable consumption and production, the study took the Key Zone with large pig production and supply as comparison object, constructed a life cycle assessment (LCA) model of pig production in the Constrained, Key, and Potential zones. The environmental impacts caused by the production of 1 ton of pork in these zones were 24.67 PE, 20.11 PE, and 20.44 PE, respectively, indicating that raising pigs in the Key and Potential zones is more environment-friendly than that in the Constrained Zone. Therefore, the relocation of pig farms from the Constrained Zone to the Potential Zone was found to be suitable for protecting water resources and environmental quality. Additionally, the Key Zone can maintain and even increase the existing breeding scale without transferring farms to the Potential Zone. LCA results showed that pork production has significant impacts on cancer risk, freshwater ecotoxicity, terrestrial eutrophication, and terrestrial acidification. Additionally, a majority of the environmental impacts result from crop and pig production, which are key processes in improving the pork supply chain. The soybean import ratio and feed conversion ratio are important indicators for reducing environmental impacts.Statement of noveltyTo evaluate whether pig farm relocation in China is consistent with sustainable consumption and production, a life cycle assessment (LCA) model of pig production in the Constrained, Key, and Potential zones was conducted. According to the results, relocating farms from the Constrained Zone to the Key and Potential zones was more environment-friendly. The Key Zone can maintain and even increase the existing breeding scale without transferring the farms to the Potential Zone. LCA results showed that the majority of the environmental impacts result from crop and pig production. Thus, further guidance and education can be provided to farmers in the Potential and Key zones. In addition, sensitivity analysis indicated that large-scale farms should reduce the feed conversion ratio to reduce environmental impacts.     

Environmental impact assessment (EIA) as collaborative learning process

A collaborative problem-solving approach was applied to environmental impact assessment of regional waste management strategy in Pirkanmaa, Finland. Various actors—interest groups, authorities, and experts—were invited to engage in joint fact finding and to exchange their views on the goals of alternative waste management strategies. The experiences of these encounters suggest that collaborative EIA can serve as a learning and civic discovery process where people can act together and find new solutions. During the process, the participants were able to reflect on their preferences and factual beliefs and to create a previously unconsidered waste management strategy that most parties found acceptable. The potential for learning and finding mutually acceptable solutions depended, however, on the legitimacy and institutional settings of the process: to what extent different perspectives were considered in the process, not only included, and how EIA was connected to a political decision-making process.     

Environmental impact assessment in the Philippines: 1977–1985

During 1977 a Philippine environmental impact statement (EIS) system was established and the National Environmental Protection Council (NEPC) was formed to develop environmental policy. Several months after its creation, NEPC was given responsibility to certify that proposed projects met EIS system regulations. With few exceptions, this requirement to gain NEPC's approval was not taken seriously by agencies. The poor record of agency compliance with the EIS system is explained by the absence of ‘controls’ to force thorough assessments. Judicial controls are absent. Procedural and evaluative controls are in place, but NEPC has neither the budget nor the political power to enforce them. Although the national EIS system is ineffective, agencies sometimes conduct informal, ad hoc environmental assessments in response to instrumental controls exercised by international funding organizations, professional controls exerted by planners, and public controls brought about by individuals and groups who would be adversely affected by projects.     

Going beyond environmental impact assessment: Environmental input to planning and design

Environmental impact assessment (EIA) has been, and remains for the time being, a very important tool of environmental management — though not always for the reasons one would expect. Major achievements of EIA have been through indirect benefits that have had little recognition to date, particularly the achievements of its stimulative and educative roles. However, EIA is evolving as a planning tool and will continue to do so, and we argue that, in time, we will be able to go beyond EIA as a separate stand alone process. We indicate the requirements for its eventual absorption into project planning and design, and the concomitant need to fully incorporate environmental issues in land use planning to address those matters that cannot be addressed on a project-by-project basis.     

Evaluation of the environmental impact assessment system in Iran

EIA in Iran was formally introduced in 1994, but to date little EIA-related research has been undertaken in the country. In this paper, the authors provide an evaluation of the Iranian EIA system, focusing on EIA legislation, administration and process. Data was collected on the basis of a literature review, document analysis and semi-structured interviews. This involved some translation from Persian into English. Evaluation of the findings indicate that Iran has adopted the democratic tools of EIA and SEA, which considering its political context is encouraging. However, currently the Iranian EIA system does suffer from weaknesses such as inadequate screening and scoping, lack of alternative consideration, public participation, EIA implementation and follow-up. The paper proposes some initial recommendations based on international experiences and sets out the direction for future research.
