这份报告的目的是推荐两个水提供方法的比较干旱地区,中国。水方法相比,基于成本和环境影响。无非在中国北京!这个城市的中国有2000万人,但只拥有世界上1/10的平均人均水资源。这个城市见证了跳棋每年在过去的几十年,这是它的地下水位下降的原因以危险的速度。北京的慢性缺水代表定期在中国面临的挑战(普华永道的报告,2013)。中国是一个国家正面临着缺水迪比卡。缺水可以由使用一些优秀的和创新技术。中国拥有世界人口的21%,但只有6%的淡水。据估计,中国400多个城市有严重的水问题(普华永道的报告,2013)。这上面的水危机地图表明,亚洲和非洲国家正面临缺水的最高水平。到2020年,预计有超过30亿人将面临水危机。这个水危机也影响严重的环境、土壤、农业和人民的健康。这是一个过程,一些盐和其他矿物质从盐水中删除。在这一过程中盐水脱盐生产淡水可以稍后用于人类消费和灌溉。

The aim of this report is to recommend the comparisons of two water provision methods for an arid region, China. The water methods are compared based on the cost and environmental impact.Look no further than Beijing in China! This city of China has 20 million of people but possess only 1/10 of the world’s average water resources per capita. This city has seen draughts per year for the past decades and this is the reason its ground water level has dropped down at perilous rate. Beijing’s chronic water shortage is emblematic  of the broader challenge facing by China on regular basis (PWC Report, 2013). China is one of the countries who are facing scarcity of water typicaly. The water scarcity can be handled by using some excellent and innovative technologies. China has 21% population of the world but it only has 6% of freshwater overall. It has been estimated that more than 400 cities of China have serious water problem (PWC Report, 2013).Chine is not the only conutry which is facing serious water scarcity but it is one of the 13 countries for example Inida, South Afica, Brazil etc; as recommended by USA are facing serious water problems across the world (Worldwatercouncil.org, 2013). Across the globle almost water scarcity impacts over 2.8 billion people at least one month of the year.This above water crisis map indicates that Asian and African countries are facing the water scarcity to the highest of its level. By 2020, it is expected that over 3 billion people will face the water crisis. This water crisis is also impacting badly over the environment, soil, agriculture and health of the people.This is a process in which some amount of salts and other minerals are removed from the saline water. In this process salt water is desalinated to produce fresh water which can be later on used for human consumption and irrigation.
