3. Introduction
Water is the source of life. 75% of the
human body is composed of water.About 70% of
the Earth is covered with water.
As the Climate Change in recent years has
become more severe, the lack of water is
getting serious,and makes people start totake
the lack of water resources seriously.

6. The reason of water shortage(Huiwen Zeng)
For the hydrological conditions in Taiwan, the
annual average rainfall is about 2,510 mm , and the
narrow terrain makes the mountains steep and the
river steep down quickly. We can't efficiently use the
rain water,and there is an uneven distribution of
precipitation. About 78%of the rainfall falls between
May and October.And typhoons and terronial rain
often cause disaters.
Due to the poor soil and water conservation,
there is a lack of groundwater resources. Despite the
construction of water reservoirs ,during the drought
year and the improper use of water. we often lack
water in winter and spring.

8. Water Crisis
and
The negative impact
(Yingrong Chen)

9. 1.The short of available water
◎Crop reduction
◎ Lead to conflict and war
◎The lack of sanitary water

10. 2. Water pollution
◎Endanger biodiversity
◎Disease and death

11. The distribution
and
status of water resources in
Taiwan
(Zihan Qiu)

12. The change of rainfall patterns
Because of the global climate change, the original rainfall
patterns produce changes, such as rainfall intensity
enhancement, causing the amount of water per unit time is
too much. It is easy to endanger the environment, and thus
makes high soil erosion in Taiwan.
• It is the amount of annual rainfall that happenes in a very
short period of time. Such rainfall not only makes us be
unable to utilize water resources efficiently but leads to
floods and droughts. total of 17 reservoirs in Taiwan, and
we only mentioned seven reservoirs ）
• Another is that the rainwater should fall in the reservoir
catchment, but it turns out to fall in the downstream of
the reservoir or at sea, which makes us be unable to
effectively block the water and utilize it.

13. Q1.What are the characteristics of Taiwan's rivers?
What are the advantages and disadvantages of
these characteristics?
1.Rivers in Taiwan flow westward or eastward
because of the separation of the Center
Mountain Range, which runs from the north
of the island tothe south.
2.The short length of rivers.

14. 3. There is a big variation in the amount of river
water.

15. Q2.What are the characteristics of Taiwan's
rivers? What are the advantages and
disadvantages of these characteristics?
Water Supply
Flood protection

16. Differences with foreign(The price of
water and Water-saving method
(Yang xin yun)

17. 1.The comparison table of the price of water in major citis in
the world.

19. • If the national income is not taken into
consideration .Among the new developed
countries in Asia,except for South
Korea ,Malaysia ,the price of water in
Japan,Singapore and Hong Kong is higher
than that in Taiwan .
• If the national income is taken into
consideration ,after calculating the
average national income, though Taiwan
is one of the countries short of water.
The price of water is relatively low.

20. 2.The distribution of water in Taiwan

21. 3.Saving method
(1).Popularize the water-saving machine (buying the
water-saving equipment is subsidized by the
government. )
The the water-
saving toilet

22. (2). Promote the water-saving Mark and System

23. (3).recycle the water and Reuse
Providing the plants can reduce 35% of the
Domestic water

24. Epilogue
Environmental damage caused by humans
may lead us to a hopeless futureIf we still
continue polluting the nature, and don’t do
somethihg to save our world.We will lose the
clean water, sky, air, and finally our living
environment.Therefore,it is very important to
save water resources andtake immediate
actions.
