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.

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.

Uneven of precipitation.

Water Crisis and

The negative impact

(Yingrong Chen)

1.The short of available water

◎Crop reduction

◎ Lead to conflict and war

◎The lack of sanitary water

2. Water pollution

◎Endanger biodiversity

◎Disease and death

The distribution and

status of water resources in Taiwan

(Zihan Qiu)

The change of rainfall patternsBecause 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.

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.

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

Differences with foreign(The price of water and Water-saving method

(Yang xin yun)

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

• 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.

3.Saving method

(1).Popularize the water-saving machine (buying the water-saving equipment is subsidized by the government. )

The the water-saving toilet

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

(3).recycle the water and ReuseProviding the plants can reduce 35% of the

Domestic water

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.
