ABSTRACT Light pollution has become one of the top issues in environmental pollution, especially concerning how secondary light pollution, such as from traffic reflective materials, influences animal distribution and behavior. In this study, 15 camera traps were set up at sites with or without reflective warning markers (RWM) in coniferous forests on Cangshan Mountain located in Dali Prefecture, China. The results showed that the number of independent photographs and species at sites without RWMs were significantly higher than those at sites with RWMs. Significant differences were found between daytime and nighttime composition of bird species and non-flying mammals between two sites.

  • Searching for Shangri-‐La
    Searching for Shangri-La Two visions of the future compete for the soul of China’s western frontier. By Mark Jenkins A cheerful group of Chinese tourists, all from eastern cities, are pushing against an enormous Tibetan prayer wheel. On a bus tour of China's wild west, they're having fun trying to get the giant instrument spinning. No less than 50 feet tall and 25 feet in diameter, the Fortunate Victory Prayer Wheel depicts, in bas-relief, China's 56 ethnic groups working together in fabled harmony. Three maroon-robed monKs, shorn and strong, arrive to give a hand. The tourists have been trying to push the prayer wheel counterclocKwise—the wrong direction in Tibetan Buddhism. The monKs reverse their energy and get the wheel twirling liKe a gargantuan top. Someone's cell phone trills a Chinese pop tune. A woman in lavender tights digs into her oversize purse. A man in a suit reaches into his blacK leather overcoat. A girl in plaid Converse high-tops rummages in her silver bacKpacK. But it is one of the monKs who steps away from the wheel and pulls the gadget from the folds of his robe. He shouts into the phone while staring out across the city below. There is the Paradise Hotel, a five-star colossus enclosing a swimming pool and an enormous white plastic replica of sacred Mount Kawagebo. There, sprawling in all directions, are gray concrete tenements. There, against a far hillside, is the restored 17th-century Ganden Sumtseling Monastery, a smaller but no less inspiring version of the grand Potala in Tibet, gleaming in the wood- smoKe haze liKe an imaginary palace.

  • 1 Testimony Before the U.S.-China Economic and Security Review
    Date of the hearing: January 26, 2012. Title of the hearing: China’s Global Quest for Resources and Implications for the United States Name of panelist: Brahma Chellaney Panelist’s title and organization: Professor of Strategic Studies, Center for Policy Research, New Delhi. Testimony before the U.S.-China Economic and Security Review Commission China has pursued an aggressive strategy to secure (and even lock up) supplies of strategic resources like water, energy and mineral ores. Gaining access to or control of resources has been a key driver of its foreign and domestic policies. China, with the world’s most resource-hungry economy, is pursuing the world’s most-assertive policies to gain control of important resources. Much of the international attention on China’s resource strategy has focused on its scramble to secure supplies of hydrocarbons and mineral ores. Such attention is justified by the fact that China is seeking to conserve its own mineral resources and rely on imports. For example, China, a major steel consumer, has substantial reserves of iron ore, yet it has banned exports of this commodity. It actually encourages its own steel producers to import iron ore. China, in fact, has emerged as the largest importer of iron ore, accounting for a third of all global imports. India, in contrast, remains a major exporter of iron ore to China, although the latter has iron-ore deposits more than two-and-half times that of India. But while buying up mineral resources in foreign lands, China now supplies, according to one estimate, about 95 per cent of the world’s consumption of rare earths — a precious group of minerals vital to high- technology industry, such as miniaturized electronics, computer disk drives, display screens, missile guidance, pollution-control catalysts, and advanced materials.

Gland, Switzerland. This report was designed by The Clarion Portfolio. Cover image: Fisherman on Zhangdu Lake, the project area of the WWF HSBC Yangtze Programme, Hubei Province, China. © WWF-Canon / Yifei ZHANG Executive Summary Executive Summary “What makes a river so restful to people is that it doesn’t have any doubt - it is sure to get where it is going, and it doesn’t want to go Hal Boyle anywhere else.” Pulitzer prize-winning columnist Perhaps there was a time when that was true, but no longer. Even the greatest of the world’s rivers can no longer be assured of reaching the sea unhindered. These days the Rio Grande/Rio Bravo River, on the border of the U.S. and Mexico, often fails to reach the Gulf of Mexico, its strength sapped by dams and irrigation works diverting water to farmers’ fi elds and city water supplies. The Indus, the Nile, the Murray-Darling, the Colorado, these are but a few of the once mighty rivers that now struggle to touch the ocean. In fact, water extraction is only one of the daunting challenges that a river faces as it makes its way to its terminus. Dams and channelization destroy habitats, cut rivers off from their fl oodplains, and alter the natural ebb and fl ow on which a river’s plants and animals depend.

In the current optimization of urban stock, it is faced with problems such as the decline of regional culture and the homogeneity of spatial form. By combing the historical evolution and value characteristics of Tunxi Old Street, introducing the concept of micro- regeneration, exploring the strategy of micro-regeneration of historical and cultural districts, this paper realizes the sustainable development of district from three dimensions of urban venation restoration, node space activation and building characteristics shaping, which can provide reference for the regeneration of other historical and cultural districts. 1 Introduction the district.

Political dynamics limit the effectiveness of many environmental governance regimes, including the UNESCO World Heritage regime. We provide new evidence on how multiscale political dynamics mediate ecosystem interventions to produce a range of outcomes. We use the World Heritage In Danger system as a model system through which to explore the evolution of UNESCO interventions, counterproductive national responses to interventions, and ways of arresting counterproductive responses. Our findings inform how we can better anticipate and account for political dynamics in designing, implementing, and evaluating environmental governance.

However, credible and consistent reports of high level threats including poaching, inadequate tourism planning, illegal wildlife trade amount to high threats to the OUV of the site. Moreover, tensions with local communities, conceptual lack of clarity and a lack of management coherence across the distinct legal, governance and management set-ups of the 15 individual protected areas are worrisome with regards to addressing these threats. Attempted management of the interconnected natural landscape by physically fragmented and not fully representative set of protected areas is highly likely to result in gradual deterioration and loss of ecosystem processes and elements which comprise the site's OUV.
