Environmental impact assessment application in infrastructural projects in Malawi

The current increase in the number of development projects in Malawi is leading to loss of natural resources and the general degradation of the environment. Both the Malawi Environmental Management Act of 1996 and the Guidelines for Environmental Impact Assessment of 1997, prescribe a list of infrastructural projects that must undergo environmental impact assessment (EIA) before their implementation. This study identifies the key limitations of EIA application to infrastructural projects in Malawi. A desktop study used to gather information in this study involved a review of several documents such as EIA reports, policies and laws, books, journals and internet articles. Primary data was obtained from policymakers, contractors, EIA practitioners and the general public using both structured and unstructured interviews, as well as through questionnaires. Focus group discussions and direct observations were employed wherever necessary in the study. Major limitations to successful EIA in infrastructural projects in Malawi include: (1) limited experience and practice of EIA practitioners; (2) cost of EIA process; (3) limited links between EIA and urban planning procedures; (4) lack of political will; (5) project delays; (6) lack of effective monitoring and auditing, (7) lack of data, especially those to be used in predictive models. This violates the principles of sustainability science and the international best practices for EIA that were developed by the International Association for Impact Assessment. It is recommended that active environmental management should actively involve the interests of all stakeholders, and that follow up of predicted environmental impacts resulting from any project should entail monitoring, auditing and reporting.     

江苏省泰州长江岸线利用演变及影响因素分析

岸线利用管理是促进岸线资源集约利用,支撑沿江开发有序、健康推进的重要保障。以泰州长江岸线利用时空变化数据库(2003~2013年)为基础,构建岸线利用类型转移矩阵,关联岸线类型与岸线条件,从规模扩张、结构变化和类型转移三方面分析岸线利用时空变化特征,结合政府部门和企业访谈以及相关研究,剖析岸线利用变化的影响因素与作用特点,为岸线利用政策调整提供依据。实证分析表明:沿江开发实施以来,泰州长江岸线利用扩张迅速,但2009年之后扩张减缓,优质岸线利用率较高,后备岸线不多。2009年以前,岸线开发以工业、仓储和港口等生产性占用为主,旅游休闲、生态保护与污染处理岸线也有较多增长。2009年之后,港口岸线扩张占主导地位,取代工业岸线成为已利用岸线调整和未利用岸线开发的主要方向。贴岸产业开发模式向港产城一体化综合开发的转变及岸线管理政策的调整共同驱动了岸线利用从工业主导向港口主导的转变,促进了岸线利用从规模扩张向结构优化转变。     

Sustaining the Gains Made in Ecological Restoration: Case Study Collingwood Harbour, Ontario

As part of the commitments made by the governments of Canada and the United States in the Great Lakes Water Quality Agreement, Remedial Action Plans (RAPs) are being developed and implemented at Great Lakes Areas of Concern. The Areas of Concern are specific places around the Great Lakes basin ecosystem where environmental quality is degraded to the point that certain beneficial uses (the ability of fish, wildlife and humans to thrive) are impaired. According to the United States and Canada Great Lakes Water Quality Agreement of 1987, the federal governments, in cooperation with state and provincial governments, are to ensure the public is consulted throughout the development and implementation of the RAPs. While not explicit in the Agreement, it is logical to posit that given the effort and investment in environmental improvements, community capacity to sustain the recovery of beneficial uses beyond the life of the RAP should be a product of the RAP. This report examines a case study to test the hypothesis that public ownership of the RAP process can result in the development of community capacity to sustain environmental recovery. The question is, were the principles of the RAP, 10 years after delisting, taken into account to ensure sustainability of growth along the waterfront and within the Town? To arrive at the answer it is important to explore the approach used in the Collingwood Harbour RAP process, and concepts and principles of sustainable cities and towns. This paper provides evidence that such principles are being applied in Collingwood and were nurtured during the development and implementation of the RAP.     

Regional environmental assessment (REA) and local Agenda 21 implementation

The implementation of sustainable development requires several support instruments. One of the major instruments in the Rio Declaration to support this process has been environmental assessment that has been given considerable emphasis as to its potential ability to help achieve more sustainable forms of development. Regional environmental assessment (REA) has shown to be effective in supporting local sustainable development process. Selected environmental assessment methods have been␣used to improve the REA exercise and provide reliable data for decision-making not only to correct environmental problems due to past unsustainable social-economic developments but also help local governments to implement Agenda 21 (AG21) plans and projects.     

SUSTAINABILITY AT THE LOCAL LEVEL: MANAGEMENT TOOLS AND MUNICIPAL TAX INCENTIVE MODEL

The implementation of sustainable development may seem a simple concept when written on paper. However to carry-out long term actions put forward by the Agenda 21 (AG21) at the local level represents one of the main challenges as municipal governments in general do not have the capacity to effectively implement the process. Regional environmental assessment (REA) has shown to be effective in supporting decision-making not only to correct environmental problems due to past unsustainable social-economic developments but also help local governments to implement sustainable actions. However this requires long-term investments of AG21 plans and projects. The allocation of regular and consistent financial resources is one of the main ingredients for the sustainable development process. But traditional plans and projects financed by national and/or international funds may not be sustainable in the long-term because they become dependent on external funding. Research demonstrate that innovative economic instruments such as ecotaxes represent a feasible alternative to sponsor local sustainability because taxes are collected permanently by the government and could be invested in continuous actions. Ecotaxes experiences have provided important reference to structure a municipal incentive model (MIM) to sponsor AG21’s environmental plans and projects on a long-term (permanent) basis. However sustainable development cannot be solely through economic investments. A comprehensive municipal environmental management scheme (MEMS) has been established to support the incentive model. The scheme seeks not only to improve local institutional framework but also incentive continuous participation of local stakeholders at all levels of society. Participatory events and the provision of incentives (educational and financial) are key to motivate society to protect the environment and support actively the sustainable development process as emphasised in the RIO-92 Conference.     

The role of the clean development mechanism in achieving China��s goal of a resource-efficient and environmentally friendly society

This paper examines the impact of the clean development mechanism (CDM) on China??s progress in building a resource-efficient and environmentally friendly society, referred to as a dual-goal society. It presents China??s CDM activities from the perspective of policy directions, administrative arrangements and capacity building as well as outlines the regional trends and distribution of CDM projects across China??s 30 provinces. Based on regression analysis of 2006?C2009 panel data, the research was able to provide estimates at provincial level of the impacts of CDM activities on China??s CO₂ emission intensity, SO₂ emission intensity and industrial dust emission intensity. The study concludes that the active CDM projects are mainly located in the less-developed central and west China where they have provided increased opportunities for sustainable development. Furthermore, the successful implementation of CDM projects across the country has significantly decreased the emission intensity of CO₂, SO₂ and industrial dust, which means that these activities have enhanced China??s ability to build the desired dual-goal society.     

Using the Framework for Integrated Sustainability Assessment (FISA) to expand the Multiregional Input–Output analysis to account for the three pillars of sustainability

Decision makers interested in promoting sustainable development must simultaneously consider the environmental, economic and social implications of any action. This article proposes the Framework for Integrated Sustainability Assessment (FISA), a methodological framework for conducting a sustainability impact assessment of any investment project. Based on a Multiregional Input–Output (MRIO) framework, FISA links the extended MRIO results with social risk data from the Social Hotspots Database (SHDB) in order to integrate the social with the environmental and economic pillars. Resulting impacts are simultaneously considered and reported by means of FISA charts, making it possible to assess the different impacts within the three sustainability pillars across countries involved in the whole supply chain of investment projects. This methodological framework can be applied not only to compare the sustainability impacts of two alternative projects, but also to derive specific recommendations aimed at minimizing the harmful social, environmental and economic effects along the whole project supply chain.     

Strategic environmental assessment application for sustainable transport-related air quality policies: a case study in Hanoi City,Vietnam

Recognition has grown among policy-makers that early in the decision-making process, there is a need for an environmental assessment of the effects of the policy, plan, and program (PPP) and their alternatives. Strategic environmental assessment (SEA) is widely recognized as a supporting tool that systematically integrates environmental aspects into strategic decision-making processes, thereby contributing to sustainable development. In this study, SEA was applied for an integrated assessment of environmental, social, and economic impacts of a wide range of scenarios for transport-related air quality policies to help decision-makers in identifying the most sustainable scenario with the purpose of reducing carbon monoxide (CO) concentrations from transport emissions in Hanoi City, Vietnam. In conducting SEA process, the urban air dispersion model MUAIR was used as a quantitative tool in prediction of CO concentrations. To evaluate the predicted impacts of scenarios, the SEA objectives concerning sustainability and the corresponding sustainable indicators were identified. Based on the likely significant predicted impacts on landscape, biodiversity, and health benefits, mitigation measures were proposed. These included planning in infrastructure development and implementation of public education campaign. The results of predicted and evaluated impacts of scenarios as well as proposed mitigation measures were taken into account for supporting sound decision-making that is consistent with the principles of sustainable development. Considering sustainable impacts of the scenarios, the SEA result clearly indicates that a combination of policy for public transport development and policy for installation of oxidation catalytic converter for motorcycles is the most sustainable scenario for reducing CO concentrations from transport emissions.     

Movement towards a low carbon emitted environment: a test of some factors in Malaysia

There exists a high global concern in different nations on environmental sustainability especially at the focal stage of increased economic growth and development process due to high level of environmental degradation and pollution. The major aim of this study was to empirically examine how to minimise carbon emissions (CO₂) in Malaysia which are mainly caused by energy production, fossil fuel consumption, population density and economic growth. The study adopted the method of autoregressive distributed lag bound testing approach to analyse the data for the period 1971–2011. The study found that economic growth in Malaysia has a direct relationship with CO₂ emissions in both the short run and the long run. Similarly, there is a positive relationship between fossil fuel consumption and CO₂ emissions over the same period. Population density was found to have positive impacts on CO₂ emissions. Contrarily, the relationship between the activities of energy production and pollution is negative in the long run. The study recommends that a targeted GDP growth rate should be set with the consideration to avoid more environmental pollution. In addition, the positive impact of fossil fuel consumption on the environmental pollution implies that there is a need to make and implement policies that will encourage the use of public transportation system more than private transportations. That is, the unnecessary use of private vehicles should be discouraged in order to reduce the extent of fossil fuel consumption.
