“UNESCO's IHP and the Water Family in Asia and the Pacific”
UNESCO Regional Science Bureau for Asia and the Pacific Jl. Galuh II No.5, Kebayoran Baru Jakarta 12110, INDONESIA United Nations Educational, Scientific and Cultural Organization
 
“UNESCO's International Hydrological Programme has since 1975 promoted international exchange and cooperation in the hydrological sciences, implemented in a series of thematic phases. Increasingly, the programme has focused on inter- and transdisciplinary approaches that seek to mobilize and optimize the contributions of science towards policy and sustainable water management. In Asia and the Pacific, the IHP Regional Steering Committee has over the past 25 years served as forum for exchange and cooperation for the region's IHP community. As of 2017, the Committee has invited the participation of the entire region, opening a new chapter in regional water cooperation.”

“Strategies for Preventing Seawater Intrusion in Coastal Aquifers”
Chunhui Lu, State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, Hohai University
 
“Groundwater stored in coastal aquifers provides water supplies for a variety of purposes. Excessive groundwater withdrawals have caused encroachment of seawater into the fresh regions of coastal aquifers, resulting in a worldwide seawater intrusion problem. Regional and global climate change, such as extreme/extended drought events and sea-level rise due to global warming, exacerbates the problem further. Seawater intrusion into coastal aquifers could cause serious consequences in terms of both environmental and economic impacts, for which effective management strategies are required. In this talk, I will introduce our recent studies on preventing seawater intrusion, including the hydraulic barrier, gas barrier, and low-permeability barrier. The developed new strategies are expected to offer new ideas and guidance for water resources managers when planning to control seawater intrusion in a coastal aquifer.”
 
 
“Impact of Climate Change on Rice Yield, Irrigation Water Requirement and Water Use Efficiency in China: Historical Simulation and Future Projections”
Weiguang Wang, State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering, Hohai University
 
“Rice is one of most important crops in China, accounting for approximately 18% of total cultivated area. Rice productivity is significantly affected by undergoing climate change and vulnerable with water stress. Therefore, investigating the responses of rice growth and water resources utilization to more pronounced climate change is of great importance for water resources planning and management in terms of maintaining the ecosystem integrity and ensuring the food security. In this study, the changes of rice yield, water consumption (ET), irrigation water requirement (IWR), water use efficiency (WUE) and irrigation water use efficiency (IWUE) from 1961-2010 in three typical sites (Kunshan and Nanjing in the Yangtze River Basin, and Kaifeng in the Yellow River Basin) in rice plantation region of China were evaluated by means of validated rice crop model ORYZA2000. Their responses to future climate scenarios of 21 century were investigated by driving ORYZA2000 with downscaling climatic data from HadCM3 (Hadley Centre Coupled Model version 3) under A2 and B2 emission scenarios with the help of a statistical downscaling method (SDSM). The results exhibit a significant decline in rice yield was identified due to obviously shortened rice growth duration. While changes of ET and IWE were different for three stations representing by significant increase of ET and IWE in Kunshan, non-significant increase in Nanjing and significant decrease in Kaifeng. Whereas accompanying production reduction, simulated WUE and IWUE for three stations all presented significant deceasing trends. The future projection results under IPCC SRES A2 and B2 emission scenarios indicated the generally negative effect of climate warming to rice yield during the 21 century due to remarkable shortened growth period, resulting in generally depressed WUE and IWUE, although there would be the distinct response of the ET and IWR to future climate change for the three stations. Further works should be carried out to capture simulation uncertainties in climate change impact assessment with consideration of interactions among anthropogenic activities, environmental and biological factors.”
