The Effects of Climate Change and Sea Level Rise on Dry Season Flows in Tien River and Hau River

引用

Journal of Environmental Science and Engineering(A) 2017年第5期6卷 239-242页

作者： Chuc huynh Department of Water Resources Ho Chi Minh City University of Natural Resources and Environment Ho Chi Minh City 700000Vietnam

Tien river and Hau river are two main branches of Cuu Long River which have hydrology regime directly effected by climate change and sea level rise. The flow of the dry season in the Tien and Hau rivers plays a key role in the socio-economic development of the Mekong Delta, especially in agricultural production. The study aims to provide useful information in socio-economic development planning and water use strategies for managers, planners and policymarkers of the provinces/cities in the Mekong Delta. This paper presents the study results in changing of dry season flows in Tien river and Hau river under the impacts of climate change in order to propose measures for protection, substainable development and water security.

Cultural Relations With Vietnam-APEC： A Look at From the Past to the Future

引用

International Relations and Diplomacy 2017年第12期5卷 736-741页

作者： huynh Quoc Thang Vietnam National University Ho Chi Minh City Vietnam

Similar to the ancient Silk Route, the Asia-Pacific Economic Cooperation （APEC） today is essentially an economic, political, and cultural interchange that includes continental culture and sea culture in interrelated relations for internal social needs related to the subjects of the country and the region that represent the whole of the East and the West. The nature of the relationship is based on the principle of consensus, voluntary with the highest goal of economic prosperity on the basis of political harmony and socio-cultural development in the effective cooperation of the direct actors. Vietnam with its geographic and cultural features in Southeast Asia has had a certain relationship with the Silk Road in the past and with APEC in the present and in the future. From that angle of view, positive ideas can be found about the factors that contribute to the sustainable development of nations, the whole region in particular, and the whole world in general.
