Detailed Ecological Footprint Accounting of Liaoning in 2006

Ecological footprint (EF) has received considerable attention as a useful indicator in the context of sustainable development. So far, EF has been used in numerous studies by academies, organizations and government authorities. However, the results of these studies failed to be comparable directly with each other due to imprecise data sets, unmodified accounting methods of pasture and fossil energy, ignored secondary products, undefined process of calculating yield factors and improper biocapacity for biodiversity. In this paper, we elaborated on EF estimating methods from six categories of consumption in order to overcome the limitations above. We adopted precise data and revised methods, calculated EF of some secondary products, introduced weighted factor to calculate yield factors and adjusted biocapacity by an appropriate amount. Meanwhile, we investigated the resource consumption of Liaoning Province in 2006 to assess EF. Its results showed that Liaoning Province overused its natural capital and was in an unsustainable state. We concluded that two specific problems that had arisen in EF assessment and gave some suggestions for Liaoning Province to improve its unsustainable state.

Unit Environmental Property Rights: Efficiency, Responsibility and System

The inexplicit efficiency of environmental property rights lies in its fuzziness. Based on the character of environmental property rights discussed, unit environment shows intra relationship between efficiency and duty of environmental property rights, and constructs a symmetrical system arrangement. Through analyzing the possibility and feasibility of unit environmental property rights, the significance of symmetrical system arrangement to avoid the inexplicit efficiency of environmental property rights is discussed in this dissertation from the aspect of the validity of offering and implementing system.

Scenario Formation of Energy Demand and CO_2 Emissionsfor Sustainable China

Co-integration theory has been employed in this paper and Granger causes are found between urbanization rate and GDP, between capital stock and GDP. Scenario analysis of GDP is performed using the GDP model established in the paper. The energy consumptions in Germany, Japan and other developed countries are analyzed and compared with the energy consumption in China. Environmental friendly scenario of energy demand and CO2 emissions for sustainable China has been formed based on the results of comparison. Under environmental friendly scenario, the primary energy consumption will be 4.31 billion ton coal equivalence （tee） and CO2 emissions will be 1.854 billion t-c in 2050; energy per capital will be 3.06 tee that is 1.8 times of energy consumed in 2005 in China and 51% of consumed energy per capital in Japan in 2003. In 2050, the energy requirement of unit GDP will be 20% lower than that of Germany in 2003, but will be still 37% higher than that in Japan in 2003. It is certain that to fulfill the environmental friendly Scenario of energy demand and CO2 emissions is a difficult task and it needs long term efforts of the whole society, not only in production sectors but also in service and household sectors,

Remote Monitoring of Expansion of Aquaculture Ponds Along Coastal Region of the Yellow River Delta from 1983 to 2015

Aquaculture ponds are one of the fastest-growing land use types in valuable and fertile coastal areas and have caused serious environmental problems. Quantitative assessment of the extent, spatial distribution, and dynamics of aquaculture ponds is of utmost importance for sustainable economic development and scientific management of land and water resources in the coastal area. An object-oriented classification approach was applied to Landsat images acquired over three decades to investigate the long-term change of aquaculture ponds in the coastal region of the Yellow River Delta. The results indicated that the aquaculture ponds in the study area undergone a sharp expansion from 40.38 km^2 in 1983 to 1406.89 km^2 in 2015, and the fast expansion occurred during the period of 2010–2015 and 1990–2000. Natural wetlands, especially mudflat, and cropland were main land use types contributing to the increase of aquaculture ponds. The patches of aquaculture ponds were consequently prevalence in the north of the Yellow River Estuary and landscape metrics indicated an increase of the aquaculture ponds of the study area in the quantity and complexity. The expansion of aquaculture ponds inevitably had negative effects on the coastal environment, including loss of natural wetlands, water pollution and land subsidence, etc. The results from this study provide baseline data and valuable information for efficiently planning and managing aquaculture practices and for effectively implementing adequate regulations and protection measures.

Environmental protection versus economic growth

This paper presents and analyses the differences in the eco-models implemented worldwide （such as whether and how carbon taxes being ＂recycled＂）, or in their efficiency parameters （inconsistent parameter values that account for different results）. This is the assumption that a real tradeoff exists between the production of environmental goods. The present article empirically proves that something must be given up in order to gain something else, and once equations are specified to trace out the path of the economy over time, the natural economic formulation of such equations will embody the notion of economic and bio-tradeoffs.

A ＂Paradox＂ in China＇s Environmental Management： An Argument From a Comparative Study on Waste Recycling Policies Between China and Japan

China appears to have a ＂paradox＂ in its environmental management policies. For example, China＇s recycling policies appear paradoxical. With its rapidly expanding economy, China is now the world＇s largest emitter of urban waste. Under such a situation, China is aiming to build up a recycling economy by enacting a number of related laws. Despite the development of waste recycling regulations, however, the load on the environment by continuously increasing waste has not reduced in China so far. What explains this seemingly paradoxical situation of waste recycling in China？ It has been pointed out in the previous study on China＇s climate change policies that environment protection falls under the rubric of sustainable development in China. The question here is whether the same story can be applied to areas other than climate change in China＇s environmental management. This paper examines it in the area of its waste recycling policy. This paper conducts an evaluation of waste recycling regulations in China by comparing it with the experience of Japan, China＇s next-door advanced country. It concludes that the waste recycling regulations in China do not primarily aim at reducing the environmental load by reducing the amount of waste but rather for the main purpose of recycling and reusing resources effectively for the sake of economic development.

The Transformation of government economy management function on a sustainable development of the environment

The ever-changing and developing ecological environment determines the functions of government to be followed by changes in economic management. The pursuit of short-term economic growth, ignoring the social promotion, will lead to excessive consume the earth＇ s resources and deteriorate environment, which pose a serious threat for the overall development of the human. Reality shows that the traditional development model faced with severe challenges. Thus, to solve environmental problems and achieve sustainable human development has become starting point and destination for the world＇ s governments to consider all issues. Government, as the actors on the path of sustainable development, is imperative to change the government＇ s economic management functions to genuinely achieve economic, social and environmental comprehensive, coordinated and sustainable development. Implementation the strategy of sustainable development requires the Chinese government at least to adopt the ideology of overall and coordinated development in the head, follow the objective law and transfer the functions of government management of the economy on the basis of sustainable development.

Concept of Integrated Waste Management as Recoverable Resources in Product Cycle

This paper presents a conceptual framework of integrated waste management which focuses on all stages of product life cycle. A mechanism of resource recovery motivating from waste in economic system （designers, producers, consumers, stakeholders in the field of disposal of the product） is suggested. The classification of institutional and economic instruments in the field of waste management as recoverable resources is developed. The author has proposed a scientific and methodical approach to the formation of an integrated waste management as recoverable resources, which is based on a set of methods of economic incentives at all stages of product life cycle and ensures the maximum possible and the environmentally safe management of wastes containing valuable resource components.

Review of Issues Related to Tourism Policies regarding Environmental Management and Customary Practices of Tourism in Gilgit-Baltistan, Pakistan

The purpose of this study is to highlight the issues and problems of tourism planning, policy formulation and implementation in Gilgit-Baltistan-mountainous region of Pakistan-a place which is abound with worth seeing natural scenes and also hub of world＇s highest mountain ranges. Tourism in many countries plays an important role in improving not only economic conditions but it also has been used as a tool to preserve environment. Tourism policy is part of national development policy in many countries, but in Pakistan this sector has been ignored in terms of proper policy formulation and also it was not considered as a potential sector for economic betterment. Although Pakistan, particularly Gilgit-Baltistan is replete with tourism resources, haplessly policy makers never focused on this sector in capitalizing these tourism resources. It also covers the traditional practices of 4 As （Access, Attractions, Accommodation and Acceptance） in Gilgit-Baltistan. In Pakistan, there have been different laws and regulations formulated with the passage of time but they have not been implemented properly. In Pakistan, tourism policy was first prepared in 1983 but it was not enforced appropriately. According to ranking of WEF T＆T （World Economic Forum Travel and Tourism） competitiveness index, Pakistan is ranked below average in policy formulation and implementation.

The Impact of the Environment Management Act （EMA） on the Accountability of Companies in Fiji

This study seeks to explore the impact of the Environment Management Act （EMA） （2005） on the accountability of three companies in Fiji. The study uses a multi-case study approach based on three subsidiaries of a conglomerate. Data collection methods include semi-structured interviews with accountants, internal auditors, and environmental officers, document reviews, and content analysis of annual reports and websites of the respective companies. The findings suggest that the EMA （2005） had some effects in terms of engendering accountability on the companies studied. Further evidence suggests that while this increased accountability has led to disclosures in annual reports and websites, these disclosures are minimal at best; furthermore, they primarily address that the stakeholder group comprised government regulatory authorities. The study provides policy implications on how environmental legislations could be designed to improve the accountability of commercial entities in developing economies. The experience and issues highlighted are also useful to other developing economies who are contemplating in developing their own environmental legislations. This paper is one of the few papers that explore the impact of environmental legislations on accountability in a developing economy context.
