5.6.2.1 New Technology

The current methods and information may not be sufficient for accurately assess-
ing the impacts of climate change. New methodologies for better understanding the
impacts of climate change are necessary, along with more sophisticated hydrologic
model which can reflect the local hydrologic characteristics and spatial and tem-
poral variations. Scientists should undertake program for development of low-cost
water technologies.

5.6.2.2 Strengthen Flood Mitigation Measures

Floods often cause damage to life and property. With the climate change, the stream
flow during the wet period may increase, and hence flood mitigation strategies
should be further examined.

5.6.2.3 Enhance Drought Protection Strategies

Although stream flow may increase, the risk of water deficits may also increase
in the future due to increased agricultural water demand. Thus, drought protection
strategies should be enhanced.

5.6.2.4 Conservation Measure

In the agricultural sector, programs which encourage cropping patterns, conserva-
tion subsidies, and financial assistance in high technology water use in irrigation
may be adopted and implemented. In the household sector, water conservation pro-
grams such as the use of water-saving devices could save a significant amount of
water.
