What is water scarcity 什么是水荒
Water scarcity occurs where there are insufficient water resources to satisfy long-term average requirements. It refers to long-term water imbalances, combining low water availability with a level of water demand exceeding the supply capacity of the natural system.
Water availability problems frequently appear in areas with low rainfall but also in areas with high population density, intensive irrigation and/or industrial activity. Large spatial and temporal differences in the amount of water available are observed across Europe.
Beyond water quantity, a situation of water scarcity can also emerge from acute water quality issues (e.g. diffuse or point source pollutions) which lead to reduced fresh/clean water availability.
Currently the main way of assessing Water Scarcity is by means of the Water Exploitation Index (WEI) applied on different scales (i.e. national, river basin). The WEI is the average demand for freshwater divided by the long-term average freshwater resources. It illustrates to which extent the total water demand puts pressure on the available water resource in a given territory and points out the territories that have high water demand compared to their resources.
Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).
Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.
Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for six billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.
水荒(water scarcity)是指在某些城市,由于天然水源(natural water source)供應(yīng)無(wú)法滿足所需用水量或水源受污染無(wú)法提供足夠清潔水的狀況。水荒應(yīng)當(dāng)通過(guò)如下措施來(lái)解決:
1. 建造水庫(kù)(reservoir)或跨流域調(diào)水(inter-basin water transfer)來(lái)補(bǔ)給;
2. 改革用水工藝,通過(guò)城市污水循環(huán)(sewage/waste water reticulating pump)再利用等多種方式來(lái)壓縮用水量(water consumption);
3. 開(kāi)發(fā)新技術(shù)和利用新水源,如海水淡化(sea water desalinization)、人工降雨(artificial precipitation)等。

Part 3 Let's Talk! 開(kāi)始交流吧!
Mom: Jimmy?
媽媽?zhuān)杭祝?br />
