Theoretical and Empirical Study on Urban Population Cawing Capacity： Case of Haidian District in Beijing

The measurement of urban population carrying capacity is the basis for cities＇ sustainable development. However, the traditional study on population carrying capacity which was based on food supply is not applicable to the single urban area. This paper built a model for the analysis of urban carrying capacity, and took Haidian District in Beijing as an example to calculate the urban carrying capacity of Haidian District in the future, which was the basis for the improvement of the population carrying capacity. This study would also provide a reference to the measurement of the urban population carrying capacity for other cities and districts in China.     

Debating ecological justice:implications for critical environmental education

This article will briefly discuss the implications of recognition of ecological justice in relation to environmental education(EE) and education for sustainable development(ESD).It is argued that the present conception of environment taught through EE and ESD negates the subjectivity of non-human species and ignores the ethical imperatives of ecological justice.Evocating environmental ethics,major directions integrating ecological justice into EE and ESD are proposed.     

Carrying Capacity:An Overview

Disputes on carrying capacity have been occurring not only among biologists and ecologists, but also among mainstream economists. Based on their efforts, the author makes an attempt to describe its origin, connotations, problems, measurement, and at the same time note the latest international progress in this field.     

Integrating Sustainable Development into Global Institutions： Reforming the United Nations

This article will briefly outline the origins, structure and functions of United Nations Environment Program and the Commission on Sustainable Development in the context of the goals of ecologically sustainable development （ESD）. Economic development, social development and environmental protection form the three interconnected parts of ESD. The achievements of the key UN environmental institutions and programs in opening up the global system to civil society, the private sector and a diversity of actors and interests, promoting the role of poverty alleviation as part of ESD through the Millennium Development Goals, and facilitating important Multilateral Environmental Agreements should be recognized. However, with these notable exceptions, organizations such as United Nations Environment Program and the Commission on Sustainable Development have become weak in scientific and technical leadership, global policy, co-ordination （inside and outside the UN） and has few achievements in the inter- national and national implementation of obligations and standards in Global Environmental Governance - including enforcement, compliance and effectiveness. This article will outline the key reasons for this inadequacy. Attention will also be focused on the way forward through of a new United Nations Environment Organization. This will require a clarification of purpose and function （within the UN system and as part of global governance structures） as well as consideration of whether it depends on system-wide UN reform. It is recommended that medium and long term strategies for reform are necessary.     

Compromises of Bali Roadmap

The Bali Roadmap, as the breakthrough on intergovernmental negotiation of climate change mitigation, having brought United States on track, is still a result of compromises. The major compromises of the Bali Roadmap are centered around three issues of quantifying emission reduction targets, developing countries＇ obligations as well as quantifying developed countries＇ financial assistance in developing countries＇ capacity building on climate change. It is found that the rationalities behind these compromises are the national interests. Due to the fact, achieving cohesion among all nations in climate change actions is very difficult. Therefore, the Bali Roadmap may lead to a tough way with distant hope. However, technology innovation and well-designed economic instruments would be helpful and supportive for further international negotiation and cooperation.     

On Touristic Ecological Footprint of Macau

Despite its tiny territory,Macau boasts a large volume of tourist activities,which serves as the pillar of its economy.Environment and natural resources are the cornerstone of tourism,but are also subject to the negative impact of tourism.Based on the theory and methodology of ecological footprint analysis,this paper calculated the touristic ecological footprint and deficit of Macau in 2009,in an effort to bring to light the current status of excessive consumption of resources by tourism.As the findings show,the non-transferable touristic ecological footprint and touristic ecological deficit of Macau in 2009 are respectively 18 300.891 gha and 12 737.584 gha,and the former is 3.29 times as large as the touristic ecological carrying capacity.Touristic ecological footprint of Macau is highly efficient in economic sense but currently tourism is developing in an unsustainable manner,so appropriate initiatives are in need to strike a balance between tourism development and resource conservation and to promote the sustainability of tourism industry of Macau.     

Energy Embodied in Goods in International Trade of China: Calculation and Policy Implications

In recent years, China’s energy demand and Greenhouse gas (GHG) emissions have grown very fast, quite an amount of which was exported as energy embodied in goods in international trade rather than consumed domestically. Starting from the concept of embodied energy, based on input-output energy analysis approach, in this paper the energy embodied in goods in international trade of China during the period from 2001 to 2006 is calculated. The results show that although China has become a net importer of petroleum since 1993, China is a net exporter of embodied energy due to international trade in goods. In 2002, the total amount of energy embodied in exported goods was about 410 million tce (ton of coal equivalent, hereinafter referred to as "tce"). Eliminating the amount of energy embodied in imported goods of about 170 million tce, the net export of embodied energy was about 240 million tce, accounting for 16% of the aggregate primary energy consumption of that very year in China, and the net export of embodied emissions was about 150 million tons of carbon. With the rapid growth of China’s international trade, assuming no structural input-output changes of among sectors, in 2006 the net export of embodied energy went up to about 630 million tce, an increase of 162 % over 2002. In addition, this paper also analyzes the possible sources of error in calculation, and also discusses the policy implications according to the result of the calculation.

Actively Dealing with Climate Change and Striving to Strengthen the Capability of Sustainable Development

Either from the perspective of the finite supply capacity of global resources and energy,or from the perspective of global environment restrictive conditions,developing countries can not repeat the old development road of developed countries,either in view of the international pressure China is currently facing,or in view of China’s own resources endowment and stages of development,we must actively face such a challenge of climate change.We must recognize that the issue of climate change may be a great restraint to the present and future eco-social development,and may also be an important driving force and new opportunity to push forward the transformation of development pattern,to take a new road of industrialization and to realize sustainable development.This demands us,on the one hand,to take the Scientific Outlook of Development as the guide to make efforts to control the emission of greenhouse gases and continuously increase the capability of adapting to climatic change,and set up the overall plan to respond to climate change of our country,and on the other hand,we should unswervingly take the road of sustainable development,save energy,optimize energy structure and strengthen biological protection in slowing and adapting to climate change.     

“一带一路”战略背景下金属产业国际产能合作研究

随着全球经济发展放缓,金属资源国内需求结构变化,资源约束压力、产能过剩等问题更加突出。如何通过国际产能合作化解金属产业难题是亟待解决的一个现实问题。本文从中国金属产业的现状出发,借鉴美、日产能转移的成功经验,在"一带一路"战略的大背景下探索适合中国金属产业开展产能合作的新模式并提出相应的政策建议。研究认为,中国已成为世界金属生产和消费大国且工业化进入中后期,具有进行国际产能合作的现实需求,"一带一路"战略为中国金属产能国际转移带来了历史契机。这种契机主要表现在沿线国家的基础设施建设热潮带来全球金属资源消费新的增长点,中国主导的"一带一路"战略构建了一种新型地缘政治格局,既能增强中国在沿线国家中的贸易话语权,也为中国开展国际产能合作提供了条件。研究指出,在"一带一路"战略下,中国金属产业的产能转移应以"互利共赢"为基础创新产能合作模式:即以产能合作推动产能转移,达到产业互补经济互惠的目的;以产能输出取代产品输出,有效回避西方国家针对中国的"双反"政策;以基础设施援建消化部分产能,在帮助沿线国家发展基础设施建设的同时消化自身部分富余产能。在合作策略上,应注重六个方面:一是充分利用"一带一路"的战略合作关系;二是实施低端转移高端做强的策略方针;三是全方位开放和深化产能合作;四是开展境外产业园区建设和有色金属精深加工工程;五是大力鼓励民营资本参与;六是创新金属矿业投资模式。

Educational initiative of Osaka University in sustainability science: mobilizing science and technology towards sustainability

One of the most important and yet difficult challenges that modern societies face is how to mobilize science and technology (S&T) to minimize the impact of human activities on the Earth’s life support systems. As the establishment of inter-disciplinary education programs is necessary to design a unified vision towards understanding the complexity of human nature, the Research Institute for Sustainability Science (RISS) launched a new program on sustainability science in April 2008. The program expects to address the issue of how to use knowledge more effectively to understand the dynamic interactions between nature and human society. This paper first offers an overview of international and Japanese initiatives on sustainability education in which we highlight the uniqueness of the attempt by the Integrated Research System for Sustainability Science (IR3S). The paper then introduces the RISS program for sustainability science, addressing the principles and curriculum design of the program. The paper discusses the main problems and constraints faced when developing the program, such as institutional barriers in building a curriculum and obtaining cooperation from faculty. To challenge these barriers and limitations, the RISS uses the program as a platform to disseminate the idea of sustainability science across the university. This attempt helps us to obtain the continuing cooperation necessary to improve and maintain the program.
