Water-Man-Earth Interactions and Sustainable Water Resources-Cooperation in East Asia and Oceania

水问题与人口增长、环境变化、工业发展和气候变化密切相关，对人类的可持续发展至关重要。我们以AP-FRIEND的名义，通过邀请大量水文研究人员，大力系统地推动解决目标区域水问题的国际合作研究。我们举行了三次会议，许多日本和外国研究人员聚集在一起。会议分别在韩国的蒂格（1998年11月7日至17日）、中国的南京（1999年10月18日至21日）和新西兰的基督城（2000年11月18日至27日）举行。在这些会议上，讨论了东亚和大洋洲水文观测数据的数据库以及包括洪水和干旱在内的河流流域全面管理问题。1999年3月5日至12日，我们向湄公河三角洲派遣了日本水文研究人员，以支持日越合作研究。研究人员调查了越南的河流水文数据库。同时，他们调查人类活动对湄公河沉积和环境的影响。我们邀请了一名韩国研究人员到日本，并派遣日本研究人员到越南、泰国、澳大利亚和新西兰进行比较水文学和合作研究。研究内容包括：洪水模型外尺度放大问题的合作研究、植被变化对洪水量影响的合作研究、植被活动调查以及人类活动和环境气候变化对水资源影响的合作研究。

Problem regarding water, which is associated with population increasing, environmental change, development ofindustry and climate change, is very important for sustainable development of human being. We strongly and systematically promote an international cooperative research for solving the water problem of the target area by gatherins a lot of hydrological researchersunder name of AP-FRIEND.1. We held three meetings at which many Japanese and non-Japanese researchers gathered. The meeting was held at Teague in Korea (November 7- 17, 1998), Nangjing in China (October 18-21, 1999) and Christchurch in New Zealand (November 18-27, 2000). At these meetings, discussions regarding database of hydrological observation data at eastern Asia and Oceania as well as total river basin management including flood and drought.2. We support the Japan-Vietnam cooperative research by sending Japanese hydrological researchers to Mekong delta from March 5-12, 1999. The researchers surveyed river hydrological database at Vietnam. At the same time, they investigate the effect of human activity on the sedimentation and environment of the Mekong River.3. We invited a Korean researcherto Japan and we dispatch Japanese researchersto Vietnam, Thailand, Australia and New Zealand to discuss the comparative hydrology and cooperative research. The subjects are as follows, cooperative research far scaling up problem off flood model, cooperative research for effect of vegetation change on flood volume, vegetation activity survey and cooperative research for effect of human activity and change of environment and climate on water resources.
