In China, on the other hand, to address the water scarcity problem in the northern part of the country the government is building a $62 billion South-to-North Water Diversion Project (SNWDP). The North is home to a large part of the population and has long been a centre of industry and agriculture, which over time has led to the overuse of groundwater. The SNWDP an example of one of many centralized government programs to address water distribution and conservation in the country. These sorts of top down initiatives are reflective of the cultures collectivist attitudes and high power distance. Social influence is top-down and behaviour changes are often driven by government regulation. In a country with high power distance, the most effective way to make change is to convince the people at the top to lead change, because they have the most influence to change things. The focus on equal distribution of resources also speaks to the collectivist nature of the country. Rather than make each region accountable for their own differences, the government is trying to redistribute unequally dispersed resources more equally.
