Trump’s Paris withdrawal and the reconfiguration of global climate change governance

<正>President Donald Trump's 1 June 2017 decision to withdraw the United States from the Paris Climate Accord understandably generated significant concern about the future of the planet.To be sure,the US withdrawal is an unfortunate setback in the global effort to address climate change;it is a missed opportunity to exercise leadership and advance the interna-     

Water resource governance in China’s regional cooperation

ABSTRACT

A series of water disputes and conflicts have gradually emerged between China and some neighboring countries after 2000, influencing China’s neighborhood relations. China increasingly realizes the importance and urgency of the water resource governance in the regional cooperation, but under complicated geopolitical context, China’s water resource governance must serve several important main functions in its regional cooperation. Overall, water resource governance is the demands of crisis management and conflict prevention, and also is a kind of positive factor that promotes sub-regional cooperation. From the perspective of the current situation, China should take more proactive attitude toward the water resource governance, expand the areas and stakeholders of the water resource governance, and thus promote the formulation of water resource governance strategy.     

Integrated climate governance in regions? Assessing Catalonia’s performance using the ‘climate learning ladder’

While developing climate change policies, regional governments and agents may have different purposes, follow different strategies, and use different appraisal procedures than those of national governments or other regions within the same countries. Climate change adds an additional source of problematisation to the functioning of traditional nation-states structures, not only at the international level but also with regard to their relations with sub-national agencies. This paper tests this hypothesis by analysing the emergence of climate strategies and capacities in region of Catalonia, north-east Spain, through the use of a novel integrated assessment tool called the ‘climate learning ladder’ that looks at four main dimensions: (1) how perceptions on climate change have evolved in this region since the beginning of the 1990s, (2) what type of incentives or systems of sanctions have triggered climate action, (3) what specific options are available or have been developed, and (4) what new institutional arrangements have been put in place during this time. Results indicate that although in Catalonia distinctive climate appraising processes have been tried, new measures have been implemented and new institutions have been created, not much of a distinctive progress regarding Integrated Climate Governance (ICG) has been achieved. Furthermore, this research shows that so far the main incentives which triggered climate action and innovation have been largely exogenous to the region.     

Analysis of the Capacity of Wellspring Conservation in Limestone Areas of Jinan

Spring water in the city of Jinan comes from the limestone areas. Understanding the capacity of wellspring conservation is a critical point to resume the perennial spewing of the spring water. The vegetation, soil, and other natural and human aspects related to the conservation are studied by using the methods of geographic information systems （GIS）, remote sensing （RS）, and field investigation. In the end, suggestions for administration and planning as well as countermeasures are put forward.     

Citizens’ perception of the resilience of Australian cities

How well does the general public understand the concept of urban resilience? We address this question via an online survey of 500+ citizens living in three large Australian cities (Sydney, Melbourne and Perth). The majority of respondents claim not to know what urban resilience means. Of the remaining respondents, understanding ranges from poor to sophisticated. To circumvent this stated lack of understanding, we cast the concept of urban resilience into a more familiar framework consisting of risk and ability to cope with threats. This allows us to assess perceptions about what may challenge the resilience of Australian cities. Two concerns clearly emerge: (1) violence and social unrest and (2) environmental threats. Analysing a number of constructs from the social psychology literature reveals that these two concerns hold different cognitive signatures, whose understanding may facilitate discussion and communication within a public engagement process.     

Analysis of the Difference of the Basic Pension by Regions

Nowadays, the disparity of the basic pension in local regions of China can be described as follows: the low level of the unification of the basic pension systems, the large disparity of the level of the basic pension, and unfairness of the enterprises’ payment for the basic pension in different local regions in China. These have already brought many negative influences, which have greatly held back the development of the society and national economy. We should build the basic pension system in all local regions of China as a whole, which can cover all people and decrease the disparity in different local regions in China.     

Temporal-spatial Characteristics of the Urbanization of Rural Land in Xinjiang

Relying on remote sensor technology, GIS and Land-sat TM digital images, the authors use spatial and statistical analysis to examine the temporal-spatial characteristics of the change caused by urban Construction in Xinjiang＇s rural areas from the end of the 1980s to the end of the 1990s. The primary findings show the following： 1） The urban construction in rural areas has increased drastically. The expansion speed of urban land use has accelerated over the past decade. The sub-land use changes caused by the urbanization of rural are characterized by salient regional differentiation among the three main regions and among the 85 counties of Xinjiang. 2） The shift of land use is mostly characterized by cultivated land and grassland being used for urban and industrial projects. Moreover, this change of land use is characteristic of regional differences. 3） Factors of rural-urban construction land use changes in Xinjiang, are undoubtedly affected by natural environment, social, economic conditions, and to a larger degree by population growth, GDP development and industrial development.     

Degradation of 17α-ethinylestradiol by ozonation--identification of the by-products and assessment of their estrogenicity and toxicity

The presence of the synthetic estrogen 17α-ethinylestradiol (EE2) in waters at low levels is a concern due to its ability to act as an endocrine disruptor. Ozone (O₃) is commonly used in water treatment and reacts with EE2 to form by-products having characteristics that are mostly unknown. The aim of this study was to identify the by-products of E2 and EE2 ozonation and determine their estrogenicity and toxicity relative to the parent compound. Ozonation by-products were identified via LC-MS analysis. The estrogenicity was measured using the YES assay, and toxicity was determined by monitoring effects on histology of fetal rat testes and testosterone secretion by these tissues. Two EE2 by-products were identified with open phenolic ring structures (masses 302 and 344 u). The Yeast Estrogen Screening (YES) assay showed a decreased but incomplete removal of estrogenicity after ozonation of EE2. Histological analysis of fetal testes revealed that neither E2 nor EE2, with or without ozonation, had any effect on seminiferous cord formation; however, a remarkable negative effect on testosterone secretion was observed, with EE2 by-products after ozonation showing the most rapid and extensive inhibition. These results show that the removal of EE2 via reaction with O₃ resulted in the formation of by-products that are less estrogenic (as demonstrated by the YES assay), but have a greater negative impact on testosterone secretion. Thus, the disappearance of the parent compound is not a sufficient endpoint, as the by-products created may be more toxic. Care should be taken when implementing oxidation applications such as ozone during waste water treatment.

The Impact of Changes of Property Rights on Farmland Use： An Empirical Study of China during Transition

In China, farmland property rights characterized by the household-responsibility system （HRS） have been improved since the reform and opening-up. The rights of use, transfer and gain become more stable, authorized and complete. This paper firstly analyzes the impact on farmland productivity, which comes from the improvement of farmland property rights. Then, an economet-ric model is built to test the above analysis. It concludes that changes of property rights will affect farmland performance in China. In the end, some policy implications are explored for fur-ther reforms.     

Roles of State Strategy of Adaptation to Climate Change in China

For the adverse impacts of climate change, China government should place the problem of adaptation to climate change on the agenda. It is time to institute and implement a state adaptive strategy to reduce the adverse impacts on economy, community and people＇s health and life by international cooperation and our own endeavor. A state strategy of adaptation to climate change should be closely linked with other current interrelated national strategies, and they should be supplemented and improved by each other. This paper discusses the roles of the state strategy of adaptation to climate change in the state climate change integrative strategy, the environmental protection strategy, and the sustainable development strategy in China. Furthermore, it proposes the main aims of the state adaptive strategy of China.     

Risk-evaluation of Hi-tech Enterprise in the Process of Approaching Global Market

In the high technology industry, small and medium sized technology enterprises (SMSTEs) play a pivotal role in advancing the whole industry. To achieve sustainable development, they need to extend their scope of business activities beyond a national view and exploit international market actively to meet international competitions that increase quickly in the form of allocating resources within the scope of the world. However, the SMSTEs are also facing risks associated with themselves during the process of exploiting international market owing to their own restrictions, so what they should do is to consider risk evaluations in exploiting the international market.

Exploration of Science Parks

1 DEVELOPMENT OF SCIENCE PARKSThe concept of science park originated in the US. Manyterms are used to describe science parks, such as researchpark, technology park, science centre, research centre,innovation centre, and with various combination of these(MacDonald, 1987). The first science park in the worldis Stanford Industrial Park established in 1951. In 1955,only seven companies were located in the park. By 1980there were ninety companies including Hewlett PackardCompany, whic…     

Recycling – the importance of understanding the complexity of the issue

Natural resources and raw materials such as metals and minerals are often taken for granted in today’s society. Without them, the offerings of an enormous variety of modern conveniences, including computers and mobile phones, would not be possible. The production of these everyday items depends on a secure, sustainable, and reliable supply of critical raw materials. In addition, product development also requires new hybrid materials when targeting lightweight structures, etc. However, the mandatory recyclability of new products or materials is not obligatory or even prevailing practice in present manufacturing business. Therefore, the main research question in this article is: “how to solve the challenge of recycling in industrial system?” In this article, a comprehensive approach to recycling based on the findings of research projects is presented. Simplified, this involves moving the challenge from the end of the product’s life cycle to the beginning, to the design or even to material development phases. Life cycle and system thinking and material know-how in the design phase are found to be essential elements of a new approach to recycling. This approach stems from the material development and market economy perspectives. Furthermore, the vulnerability of the industrial system to create uncertainty to recycling is also demonstrated.
