800 entriesWith its coverage of environmental issues, global economics, online communications, and the latest political developments, this Encyclopedia is truly a 21st-century work. While including many articles about China's earliest history - going back more than 5,000 years - the Encyclopedia is focused on the events, concepts, and people that matter today. The authors of its 800 accessibly written and lavishly illustrated articles, which range from 600 to 6,000 words, are scholars at major Chinese and Western universities and research institutes.

The character, the motion and the proportion of environment-induced migration have radically changed in recent years. Environment-induced migration is an increasingly recognized fact and has become one of the main challenges of the 21st century, and needs to be focused on to ensure sustainable growth. This new stance is due to the changing character of environmental degradation. Global environmental issues, including climate change, loss of biodiversity, river and oceanic contamination, land degradation, drought, and the destruction of rainforests, are progressively stressing the earth’s ecosystems. Among these issues, climate change is one of the most severe threats. Climate change alone does not directly induce people to move but it generates harmful environmental effects and worsens present vulnerabilities. The current study aims to provide cornerstone links between the effects of climate change, migration decisions, displacement risk and conflicts in the example of Afghanistan, as a country that is extremely affected by both climate change and conflicts, and outline priority policy focuses to mitigate the current situation in the country.

ON May 2nd, I attended the New Scientist Environmental Road Show in Sydney. Apart from promoting New Scientist, the show was intended to raise awareness of the environmental issues confronting humanity in the 21st Century. The presentation began with a series of video clips of prominent environmentalists expressing concern at the failure of nations to act decisively on global environmental problems. New Scientist staff then presented three scenarios of the environmental future based on global warming, atmospheric pollution, and growth of the World's population followed by a panel discussion and comment from the audience. In all, an enjoyable and informative, if somewhat predictable, evening.
