报告内容简介：

One direct impact of climate change is human migration. Environment-related migration has significant impacts on the well-being of migrants and has reciprocal effects on landscape structure and ecosystem services. The dynamics is even stronger in rural drylands as they face forces from multiple directions: climate change and subsequent changes in landscape structure and ecosystem services, out-migration of the young and subsequent remittances and brain drain, rapid population growth and demographic structure changes, globalization, and government interventions and geopolitics. This presentation includes two parts. One is about the ecological migration in rural drylands of Kyrgyzstan, Mongolia, and China within the coupled human and natural system framework. The other is about amenity-driven rural migration in the U.S.

报告内容简介：

In this study we present a novel research approach to obtaining behavior-based evidence of regional climate change attitudes, using the 2011 Fukushima nuclear plant incident as a natural experiment. Our approach allows us to produce the first non-survey-based empirical evidence of a trans-Atlantic divide in public opinion on the environment and climate change that investors assign to fossil-based and renewable energy. This value is based on the perceived potential of these fuel types to substitute for nuclear generation in the aftermath of the Fukushima crisis. We carry out an event study to examine differences in abnormal returns of global coal and renewable energy companies on European and American stock exchanges. We find that investors trading on U.S. markets exhibit a significantly more favorable perception of coal stock profitability, while investors trading on European exchanges display a more favorable perception about profitability of renewable energy stocks.
