There are 17 countries that have riparian relationships with western China, most of which are water-short countries. All are listed by UN ESCAP as countries with potential water crisis. The co-operative development and coordinated management of international rivers in western China is an important step toward the implementation of the national Great Western Development program. Taking into account of the national strategy and object hierarchy, as well as the development demand of the western region, it is necessary to pursue the multi-disciplinary study of the equitable allocation, utilisation, and eco-environment protection of transboundary water resources in the region. Such efforts will undoubtedly provide scientific evidence and support for the decision-making of the environmental protection and ecological construction and management in the western regions, the enforcement of the sub-regional economic co-operation, mitigation of trans-boundary conflicts, and enhancing bio-diversity conservation.展开更多

The main reason is the natural and man-made results. This article proposes the specific measures to protect the ecological environment in Heihe River water source district.展开更多

Its amphibian nature of lower delta area where used to be covered by the sea around 5000 years ago provides a water-based settlement for the citizens. Rivers as an agricultural irrigation system are also used for daily consumption, transportation, and drainage channels. Bangkok was established in 1782 as the capital of Thailand by King Rama I of the Chakri Dynasty. The location is on a flood plain delta of the Chao Phraya River with the same consideration as the up north old capital Ayutthaya;the river is performed as a natural defense against enemies and also provides a water-based settlement for the citizens. The worst flood in Thailand’s history occurred during the 2011 monsoon season;July to November;that became the severest flood disaster hit parts of the capital city of Bangkok and resulted in a total of 815 deaths and 65 of Thailand’s 77 provinces were declared flood disaster zones, and over 20,000 square kilometers (7700 square miles) of farmland was damaged. The most affected areas were the recent capital Bangkok and the old capital Ayutthaya. The major causes were not only from the natural disaster but also water management failures from the human disaster. The studies aimed to include the survey of after-flood areas, reviewing the history of the waterfront communities and their attitudes toward development and changes, then discussed threats and crisis to the cultural landscape, the cause and effects of the disaster, the theoretical framework of the best management practices and the resolutions models proposed by the involved authorities. Whilst, history also gives us a sense of identity and traditional wisdom, the paper tried to find a paradigm shift and invented best practices for future generation flood protection using “<em>the meaning and spirit of cultural landscape</em>” model.展开更多
