Water plays an important role in our lives. All living things need water to live. 70% of the earth's surface is made up of water. Most water is salt water which is less likely to be used in our daily lives. Less than 2% of the water on Earth is fresh water that can be used by humans (Western Upper Peninsula Center for Science, Mathematics and Envorimental Education & Sustainable Futures Institute). Fresh water resources are therefore very limited. Furthermore, these water resources are not distributed evenly between areas. For example, in China, the northern region has only 5% of the fresh water resources that support around 40% of the population. Additionally, water is increasingly scarce in China due to population growth and rapid industrialization in recent decades. It is inevitable that total water consumption will increase along with China's economy while water scarcity worsens and, therefore, the topic of water use and conservation deserves attention. discussed. In this article, I will discuss water use and conservation in China with focus on industrial sectors and develop an intervention program with its evaluation. Basically, the body of the document can be divided into three parts as follows: the context and policy issue, my intervention program and the program evaluation. Background and Policy Issue China has the largest population in the world. In recent years, water demand has increased rapidly to 4.13*1012 m3, while China's overall water supply continues to decline every year. Climate scientists estimate that China's total water supply is declining by more than 90 trillion gallons per year (Cho, 2011). More than 450 cities in China suffer from serious water shortage problems. The problem is becoming more and more serious... middle of document ...... references or changes are statistically significant. Multiple regression analysis will be performed to test the cause and effect relationship between program outcome variables and program financial incentives.5) Summarize the results and draw a conclusion6) Feedback on program improvementFinally, after reviewing Based on the findings and results, we can make some recommendations about the program. If the program does not meet my expectations, additional questions should be asked to diagnose program failure, such as "Are grants, subsidies, and reimbursements appropriate for businesses to be ready to adopt recycling?" water ? and “Is the duration of the study long enough to detect changes and program effects?” Benefit-Cost AnalysisBefore discussing benefit-cost analysis in detail, the basic steps and framework of benefit-cost analysis are shown in the figure 1.
