. In recent years, the issues of large energy consumption and degraded living environments have attracted considerable attention in developed and developing countries. Hence, green housing (GH) has become a popular strategy for achieving sustainable urbanization. The demand in the GH market played an important role in promoting GH. In China, whether potential consumers will pay for GH remains unclear. In this circumstance, this study aims to explore the willingness of construction practitioners, who are regarded to have more knowledge concerning GH, to pay for GH in China. Based on the theory of planned behavior (TPB), nine critical factors related to practitioners' willingness to pay (WTP) were examined through face-to-face interviews using a questionnaire survey. A total of 180 construction participants in Jinan were investigated in this study. A binary logistic regression model was used to analyze the collected data. The research finding revealed that only 68 respondents were willing to pay for GH. Four factors showed significant and positive influences in practitioners' WTP, including environmental awareness, GH comfort, government incentive, and neighbors'/friends' assessment. By contrast, GH price displayed a significant and negative influence in practitioners' WTP. The remaining factors, namely, mature GH market, degree of popularity, publicity of GH from developers, and GH affordability, showed insignificant relationships with the practitioners' WTP. The research findings can provide a helpful reference for policy makers to formulate effective incentive policies in the promotion of GH

Changes in glacial lakes and the consequences of these changes, particularly on the development of water resources and management of glacial lake outburst flood (GLOF) risk, has become one of the challenges in the sustainable development of high mountain areas in the context of global warming
. This paper presents the findings of a study on the distribution of, and area changes in, glacial lakes in the Koshi basin in the central Himalayas. Data on the number of glacial lakes and their area was generated for the years 1977, 1990, 2000, and 2010 using Landsat satellite images. According to the glacial lake inventory in 2010, there were a total of 2168 glacial lakes with a total area of 127.61 km2 and average size of 0.06 km2 in the Koshi basin. Of these, 47% were moraine dammed lakes, 34.8% bedrock dammed lakes and 17.7% ice dammed lakes. The number of glacial lakes increased consistently over the study period from 1160 in 1977 to 2168 in 2010, an overall growth rate of 86.9%. The area of glacial lakes also increased from 94.44 km2 in 1977 to 127.61 km2 in 2010, a growth rate of 35.1%. A large number of glacial lakes in the inventory are small in size (≤ 0.1 km2). End moraine dammed lakes with area greater than 0.1 km2 were selected to analyze the change characteristics of glacial lakes in the basin. The results show that, in 2010, there were 129 lakes greater than 0.1 km2 in area; these lakes had a total area of 42.92 km2 in 1997, increasing to 63.28 km2 in 2010. The distribution of lakes on the north side of the Himalayas (in China) was three times higher than on the south side of the Himalayas (in Nepal). Comparing the mean growth rate in area for the 33 year study period (1977-2010), the growth rate on the north side was found to be a little slower than that on the south side. A total of 42 glacial lakes with an area greater than 0.2 km2 are rapidly growing between 1977 and 2010 in the Koshi basin, which need to be paid more attention to monitoring in the future and to identify how critical they are in terms of GLOF

Rapid urbanisation, growing urban populations, environmental issues and climate change all represent significant challenges for water resource management, the delivery of essential water and sanitation services and environmental protection
. As a result, traditional approaches that have relied heavily on large-scale infrastructure development are making way for new approaches such as the portfolio-based approach to planning and management. In an urban context, this includes integration of all components of the urban water cycle, and most state governments in Australia have embarked on implementing this integrated approach by having a mix of water supply sources including demand management and conservation measures. However, effective implementation of this approach depends on policies and regulations and encounters various impediments. Accordingly this chapter focuses on the City of Adelaide in South Australia and explores the legal and policy challenges for implementing an integrated urban water management plan in Metropolitan Adelaide. Drawing on the results of governance studies carried out in Australia that included a literature review, stakeholder and community surveys, the chapter attempts to better understand the barriers to transitioning Adelaide to a water-sensitive city

The southern boundary between India and the Tibetan Plateau represents a classical case of continental subduction, where the Indian continental lithosphere is subducted northwards beneath the Tibetan Plateau
. At the northern boundary, southward subduction of Asian lithosphere beneath the Tibetan Plateau has also been proposed7, but imaging has been hampered by inadequate data quality. Here we analyse the plate tectonic structure of the northern boundary between Tibet and Asia using the S receiver function technique. Our passive source seismic data build on, and extend further northwards, the existing geophysical data from the International Deep Profiling of Tibet and the Himalaya project8, 9, 10. We detect, beneath central and northern Tibet, a relatively thin, but separate, Tibetan lithosphere overriding the flat, southward subducting Asian lithosphere. We suggest that this overriding Tibetan lithosphere helps to accommodate the convergence between India and Asia in central and northern Tibet. We conclude that the Tibetan–Himalayan system is composed of three major parts: the Indian, Asian and Tibetan lithospheres. In the south, the Indian lithosphere underthrusts Tibet. In central and northern Tibet a separate, thin Tibetan lithosphere exists, which is underthrust by the Asian lithosphere from the north

Annotation:::: The lead author, Bao Guangjing is a doctoral student and lecturer of School of Life Sciences, Yunnan University
. His paper focuses on the resettlement of local residents caused by the protection of local natural reserves and industrial development of Nujiang prefecture, Yunnan province. The resettlement of local people and complicated human-land relationship are the main subjects of study, and the article mainly deals with life science and ecological security and only minimally with the issue of remittance. It elaborates on the displacement of local residents, and explores ways of solving the various conflicts between humans and land and other problems in the local society. The authors generally use the method of documental study, engaging in a quantitative analysis of several documents and pieces of literature related to the reasons for resettling local residents of Nujiang. Through their analysis, they find out that firstly, Nujiang is an ecologically vulnerable area with most of mountain people living under poverty line; secondly, it is necessary for those mountain people to move to other places with better living conditions; thirdly, development of a hydropower station helps promote local poverty alleviation; and fourthly, resettlement of mountain people plays a positive role in local socioeconomic development and also the protection of natural reserves
