Exploration of sustainable development by applying green economy indicators

Following the global trend of sustainable development, development of green economy is the best way of slowing the negative ecological and environmental impact. This research establishes the Taiwan's green economic indicators based on the ecological footprint and energy analysis. The results are as follows: Taiwan's ecological footprint in 2008 intensity index was at 4.364; ecological overshoot index was at 3.364, showing that Taiwan's ecological system is in overload state. Moreover, this study utilizes energy analysis model to study the sustainable development of Taiwan. Findings showed that total energy use in 2008 was 3.14 × 10(23)?sej (solar energy joule, sej), energy of renewable resources was 1.30 × 10(22)?sej, energy of nonrenewable resources was 2.26 × 10(23)?sej, energy of products from renewable resources was 1.30 × 10(22)sej, energy of currency flow was 8.02 × 10(22)?sej and energy of wastes flow was 6.55 × 10(22)?sej. Taiwan's energy per capita and the utilization rate of energy is lower while the environmental loading rate is significantly higher comparing to some other countries. The foregoing findings indicate that Taiwan currently belongs to an economic development pattern based on high resource consumption. The economic development is mainly established on the exploitation and utilization of nonrenewable resources. Therefore, Taiwan should change the development pattern, regulate the industrial structure, promote the utilization rate of resources, develop green pollution-free products, and enhance the sustainable development of ecological economic system.     

Evaluating environmental impact assessment (EIA) in the countries along the belt and road initiatives: System effectiveness and the compatibility with the Chinese EIA

BRI has a great potential to improve necessary infrastructure, regional development, connectivity, and industrialization, and promote the sustainable transformation of the countries along the routes. Despite the remarkable aims, economic growth ambition of BRI may clash with the sustainability of the ecosystem given the scales of operations in environmentally sensitive regions, and the amount of material and energy needed. Therefore, the sustainable potential and environmental stewardship of the BRI will largely depend on the standard of strategic environmental and social management, and integration between China and partner countries of respective priorities, policies, and regulations. The effectiveness and compatibility of environmental impact assessment systems (EIA) remain largely unknown, especially across the diverse ecological, social, economic and political contexts represented in countries along the BRI. We review and compare EIA systems on the contextual factors that moderate the effectiveness and compatibility with China's policy. This work helps to identify strategies to more efficiently and effectively implement BRI towards sustainable development.     

Assessment of urban sustainability efficiency based on general data envelopment analysis: a case study of two cities in western and eastern China

Sustainable urban development focuses on enhancing urban well-being, while also balancing the demands of urban social and economic development, natural resource consumption, and environmental pollution. This work used general data envelopment analysis to assess the urban sustainability efficiency (USE) and sustainability potential (SP) in Lanzhou and Xiamen, two cities that are characteristic of urban areas in western and eastern China. The assessment indicator system included important natural and urban welfare factors as input and output indices, respectively. The results showed that overall urban sustainability efficiency increased in Lanzhou and Xiamen from 1985 to 2010, but that the sustainability of natural resources clearly decreased. The urban sustainability efficiency of Xiamen was higher than that of Lanzhou, and the sustainability potential of Xiamen was lower than that of Lanzhou; this indicates that Xiamen performed better in terms of urban sustainable development. The urban sustainability efficiency in Xiamen has increased with increasing urban population, and the rate and scale of economic development have been higher than in Lanzhou. The assessment and analysis performed in this study show that cities with different natural resources and development characteristics have different forms, patterns, and trajectories of sustainable development.     

Improving the effectiveness of planning EIA (PEIA) in China: Integrating planning and assessment during the preparation of Shenzhen's Master Urban Plan

The enactment and implementation of the 2003 EIA Law in China institutionalised the role of plan environmental impact assessment (PEIA). While the philosophy, methodology and mechanisms of PEIA have gradually permeated through the various levels of government with a positive effect on the process and outcome of urban planning, only a few cities in China have so far carried out PEIA as a Strategic Environmental Assessment (SEA)-type procedure. One such case is the southern city of Shenzhen. During the past three decades, Shenzhen has grown from a small town to a large and booming city as China has successfully and rapidly developed its economy by adopting the “reform and open door” policy. In response to the challenges arising from the generally divergent processes of rapid urbanisation, economic transformation and environment protection, Shenzhen has incrementally adopted the SEA concept in developing the city's Master Urban Plan. As such, this paper reviews the effectiveness of PEIA in three ways:

• •as a tool and process for achieving more sustainable and strategic planning;
• •to determine the level of integration of SEA within the planning system; and,
• •its effectiveness vis-à-vis implementation.

The implementation of PEIA within Shenzhen's Master Urban Plan offers important insights into the emergence of innovative practices in undertaking PEIA as well as theoretical contributions to the field, especially in exploring the relationship between PEIA and SEA and highlighting the central role of local governing institutions in SEA development.     

Technological innovation and sustainable development : Does the stage of development matter?

Technological innovation has generated much interest among scholars, practitioners, and policymakers as a critical instrument for achieving sustainable development. Although the relationship between technological innovation and sustainable development has been extensively discussed in the academic and policy circles, little studies have empirically examined the simultaneous impact of technological innovation on the three pillars of sustainable development. To fill this gap, the present study examines the ability of technological innovation to simultaneously promote economic progress and advance social and environmental conditions in the case of 75 low-, middle-, and high-income countries by demonstrating how this impact differs across the stages of economic development. From both long-run estimates and causality analysis, our findings reveal that technological innovation contributes simultaneously to the three pillars of sustainable development only in the case of rich countries; however, it only affects the economic and environmental dimensions in the middle-income countries, and no impact is found in the case of low-income countries. Future research directions, policy and managerial implications are also discussed.     

Landscape ecological security assessment based on projection pursuit in Pearl River Delta

Regional landscape ecological security is an important issue for ecological security, and has a great influence on national security and social sustainable development. The Pearl River Delta (PRD) in southern China has experienced rapid economic development and intensive human activities in recent years. This study, based on landscape analysis, provides a method to discover the alteration of character among different landscape types and to understand the landscape ecological security status. Based on remotely sensed products of the Landsat 5 TM images in 1990 and the Landsat 7 ETM+ images in 2005, landscape classification maps of nine cities in the PRD were compiled by implementing Remote Sensing and Geographic Information System technology. Several indices, including aggregation, crush index, landscape shape index, Shannon’s diversity index, landscape fragile index, and landscape security adjacent index, were applied to analyze spatial–temporal characteristics of landscape patterns in the PRD. A landscape ecological security index based on these outcomes was calculated by projection pursuit using genetic algorithm. The landscape ecological security of nine cities in the PRD was thus evaluated. The main results of this research are listed as follows: (1) from 1990 to 2005, the aggregation index, crush index, landscape shape index, and Shannon’s diversity index of nine cities changed little in the PRD, while the landscape fragile index and landscape security adjacent index changed obviously. The landscape fragile index of nine cities showed a decreasing trend; however, the landscape security adjacent index has been increasing; (2) from 1990 to 2005, landscape ecology of the cities of Zhuhai and Huizhou maintained a good security situation. However, there was a relatively low value of ecological security in the cities of Dongguan and Foshan. Except for Foshan and Guangzhou, whose landscape ecological security situation were slightly improved, the cities had reduced values in landscape ecological security, with the most decreased number 0.52 in Zhaoqing. Results of this study offer important information for regional eco-construction and natural resource exploitation.

A decision-support system for sustainable urban metabolism in Europe

Urban metabolism components define the energy and material exchanges within a city and, therefore, can provide valuable information on the environmental quality of urban areas. Assessing the potential impact of urban planning alternatives on urban metabolism components (such as energy, water, carbon and pollutants fluxes) can provide a quantitative estimation of their sustainability performance. Urban metabolism impact assessment can, therefore, contribute to the identification of sustainable urban structures with regards, for example, to building types, materials and layout, as well as to location and capacity of transportation and infrastructural developments. In this way, it enables the formulation of planning and policy recommendations to promote efficient use of resources and enhance environmental quality in urban areas.The European FP7 project BRIDGE (sustainaBle uRban plannIng Decision support accountinG for urban mEtabolism) has developed a decision-support system (DSS) that systematically integrates urban metabolism components into impact assessment processes with the aim of accurately quantifying the potential effects of proposed planning interventions. The DSS enables integration of multiple spatial and non-spatial datasets (e.g. physical flows of energy and material with variables of social and economic change) in a systematic manner to obtain spatially defined assessment results and to thus inform planners and decision-makers. This multi-criteria approach also enables incorporation of stakeholders' perceptions in order to prioritise decisive assessment criteria. This paper describes the methodological framework used to develop the DSS and critically examines the results of its practical application in five European cities.

Sustainability as the key to prioritize investments in public infrastructures

Infrastructure construction, one of the biggest driving forces of the economy nowadays, requires a huge analysis and clear transparency to decide what projects have to be executed with the few resources available. With the aim to provide the public administrations a tool with which they can make their decisions easier, the Sustainability Index of Infrastructure Projects (SIIP) has been defined, with a multi-criteria decision system called MIVES, in order to classify non-uniform investments. This index evaluates, in two inseparable stages, the contribution to the sustainable development of each infrastructure project, analyzing its social, environmental and economic impact. The result of the SIIP allows to decide the order with which projects will be prioritized. The case of study developed proves the adaptability and utility of this tool for the ordinary budget management.

Environmental Impact Assessment in the Visegrad Group countries

The Environmental Impact Assessment Directive (EIA Directive) has created a reference framework for the implementation of the system of Environmental Impact Assessment (EIA) into the legal systems of the Member States of the European Union, including the countries belonging to the Visegrad Group (V4): Poland, Slovakia, the Czech Republic and Hungary. The Directive was the basis for the introduction of compulsory stages of the EIA process in the V4. The stages were then adapted to national requirements, including thresholds of the qualifying criteria of projects at the screening and scoping stages. The EIA system in the analysed countries has been growing, changing and being modified together with the political and economic changes of the last 30 years. Although all Visegrad Group countries are members of the EU and should harmonize the provisions of the EIA Directive and its amendments, there still exist singularities in each country's national EIA legislation, in terms of complementarities among the V4 countries, access to information resources, protection of natural resources, mitigation of socio-environmental impacts, or transboundary impact assessment. The article compares and evaluates the EIA systems in the four countries, specifies similarities and differences in the implementation of administrative proceedings and points out opportunities to strengthen the system. It presents selected results of a study conducted in 2013 within the framework of the international project “Assessment of the quality of the environment in the V4 Countries” (AQE V4). This paper indicates examples of good practice in the EIA systems and the obtained results are compared regarding the amendments to the current European Union EIA Directive.

Review of sustainability indices and indicators: Towards a new City Sustainability Index (CSI)

The purpose of this paper is to discuss conceptual requirements for a City Sustainability Index (CSI) and to review existing major sustainability indices/indicators in terms of the requirements. The following indices are reviewed: Ecological Footprint (EF), Environmental Sustainability Index (ESI), Dashboard of Sustainability (DS), Welfare Index, Genuine Progress Indicator (GPI), Index of Sustainable Economic Welfare, City Development Index, emergy/exergy, Human Development Index (HDI), Environmental Vulnerability Index (EVI), Environmental Policy Index (EPI), Living Planet Index (LPI), Environmentally-adjusted Domestic Product (EDP), Genuine Saving (GS), and some applications of composite indices or/and multivariate indicators to local or regional context as case studies. The key conceptual requirements for an adequate CSI are: (i) to consider environmental, economic and social aspects (the triple bottom line of sustainability) from the viewpoint of strong sustainability; (ii) to capture external impacts (leakage effects) of city on other areas beyond the city boundaries particularly in terms of environmental aspects; (iii) to create indices/indicators originally for the purpose of assessing city sustainability; and (iv) to be able to assess world cities in both developed and developing countries using common axes of evaluation. Based on the review, we conclude that it is necessary to create a new CSI that enables us to assess and compare cities' sustainability performance in order to understand the global impact of cities on the environment and human life as compared with their economic contribution. In the future, the CSI will be able to provide local authorities with guidance toward sustainable paths.     

基于形态空间格局分析方法和最小累积阻力模型的北京市平原区造林工程生态格局分析

为了科学评估北京市平原区造林工程的生态影响,利用高分卫星数据获取2018—2020年北京市平原区造林面积、分布及变化信息,分析了造林工程的空间格局特征,并采用形态空间格局分析(MSPA)方法及最小累积阻力(MCR)模型,构建了北京市平原区生态网络,通过情景模拟分析造林工程对生态源地、生态廊道产生的影响。结果显示,2018—2020年北京市平原区造林工程主要沿西北东南方向实施,实现了对原有林地资源分布不均衡问题的解决。热点建设区域为北部的延庆及东南部的通州、大兴,呈现由城市边界逐步向市中心蔓延的发展趋势。在不考虑其他因素对土地利用的影响的前提下,造林工程的实施使平原区林地面积增长了9.8%。通过情景模拟发现,造林工程的实施使生态网络向连通、完整、均衡方向发展。其中,生态源地面积增长了131.0 km²,主要生态源地连通性提升了41.1%,生态廊道的分布由主要分布在西北部山区向西北、东南两个方向均有密集分布转变。综上,造林工程的生态环境效应显著,造林工程的实施对生态环境质量改善具有重要意义。     

Good governance for sustainable development goals: Getting ahead of the pack or falling behind?

This article extends previous sustainability literature by demonstrating the effectiveness of good governance in rebalancing the economic, environmental, and social components of sustainable development. Good economic, political, and institutional governance are considered as conditional variables, which allow rebalancing these three components in the case of 20 selected MENA economies for the period 1996–2014. Using simultaneous-equation modeling approach, we find that (i) political and institutional governance positively contribute to the three components of sustainable development; (ii) there exists a two-way linkages between human development and economic growth, meaning that they are interrelated and may very well serve as complements to each other; (iii) increased economic growth conducts to further emissions, which, in turn, decreases economic growth; (iv) enhancing human development conducts to a reduction in carbon dioxide emissions, which, in turn, negatively affects human development; (v) improving both political and institutional governance permits MENA governments to moderate both the negative impacts of carbon emissions on economic growth and human development and the positive impact of economic growth on increasing emissions, and as a result sustainable development.
