Nature-based tourism destinations-locations in which economic viability and environmental responsibility are sought-are sensitive to climate change and its effects on important environmental components of the tourism areas. To meet the dual roles, it is important for destination marketers and resources managers to provide quality experiences for tourists and to induce tourists' environmentally responsible behavior in such destinations. This study documents the importance of perceptions toward climate change and tourist experiences in determining tourists' environmentally responsible behavior while enjoying holidays at nature-based tourism destinations in Jeju Island, South Korea. Two hundred and eleven Korean and 204 Chinese tourists marked dominant tourist arrivals to the island, and responded to the survey questionnaire. Results showed that perceptions toward climate change and tourist experiences affect Korean tourists' environmentally responsible behavior intentions, whereas tourist experiences-not perceptions toward climate change-only significantly affect Chinese tourists' behavior intention. In a nature-based tourism context under the pressure of climate change and adverse environmental effects as consequences of tourism activities, resources managers and destination marketers need to develop environmental campaigns or informative tourist programs to formulate environmentally responsible behavior as well as to increase tourist quality experiences among domestic and international tourists.

The Environmental Kuznets Curve hypothesis suggests that sustainable economic growth can be achieved in transitional countries after the threshold level of per capita income. And trade openness is also one of the critical factors to help transitional economies reduce carbon dioxide emissions and economic growth simultaneously through the combination of scale, composition, and technique effects. This paper is designed to explore the effect of trade openness on the environmental quality and investigate the existence of the environmental Kuznets curve hypothesis for a panel of CIS countries over the period of 2000-2013. The two-equation model is used to estimate the direct effect of trade openness on CO2 emissions and the indirect effect via per capita income. The instrumental variable techniques are employed to consider for endogeneity of per capita income and trade openness to estimate the indirect effect, and GLS analysis is conducted to estimate the direct effect of trade openness on CO2 emissions. The result shows that trade openness increases CO2 emissions directly while indirectly decreasing it due to its negative effect on per capita income. This study provides multiple policy implications for the sample countries to help them achieve sustainable economic growth while improving environmental quality.

This study developed three scenarios of future land use/land cover on a local level for the Kyung-An River Basin and its vicinity in South Korea at a 30-m resolution based on the two scenario families of the Intergovernmental Panel on Climate Change (IPCC) Special Report Emissions Scenarios (SRES): A2 and B1, as well as a business-as-usual scenario. The IPCC SRES A2 and B1 were used to define future local development patterns and associated land use change. We quantified the population-driven demand for urban land use for each qualitative storyline and allocated the urban demand in geographic space using the SLEUTH model. The model results demonstrate the possible land use/land cover change scenarios for the years from 2000 to 2070 by examining the broad narrative of each SRES within the context of a local setting, such as the Kyoungan River Basin, constructing narratives of local development shifts and modeling a set of 'best guess' approximations of the future land use conditions in the study area. This study found substantial differences in demands and patterns of land use changes among the scenarios, indicating compact development patterns under the SRES B1 compared to the rapid and dispersed development under the SRES A2.
