Comprehensive foreign media reports  In recent years，serious drought and floods in many places around the world，Treating the high attention of the academic community about the problem of "unsafe water use"。But，Most of the water source indicators focus on assessing the availability of water resources or the total amount of water conservancy infrastructure，Social population data that cannot be provided for "unsafe water"。According to the official website of Northwest University of the United States, recently reported，Professor of the school's anthropology and global health research professor Sera Young (Sera Young) bet365 live casino games and others have developed the "Personal Water Unsafe Experience Measurement Table"，For the first time, I measured low -income and middle -income countries in the country's unsafe situation in 2021，In -depth discussion of the impact of the population structure of various countries and the epidemic of new crown pneumonia on personal water safety。The research results have been released recently in the journal "Liu Ye Dao"。

 

In the past 10 years，Scholars focus on measuring the obtaining channels and infrastructure coverage of drinking water。2021，Yang and others published the "Personal Water Unsafe Experience Measurement Table"。This is the first measurement of personal water source acquisition、Cross -cultural measuring table for usage and stability，It has been widely used now。First，This measuring table investigates the problem of personal water -related issues within 12 months through 12 problems bet365 Play online games (cooking、Bathing and Emotional Health) appears frequency。If personal water is used, it is safe and stable，0 points; I have encountered problems in 1-2 months，1 point; problems in some months，2 points; almost every month, personal water problem，3 points。The score range of the measuring table is 0-36 points，If a person's total score is 12 points or higher，It indicates that the person’s water state is very unsafe。The measuring table also evaluates the relationship between the unsafe situation of individual water in the summary sample and the social population characteristics of different countries and regions。

 

To explore the national level、How does the difference in population level and socio -economic level affect the degree of unsafe water use in low -income and middle -income countries，Researchers measured the southern Africa of Sahara bet365 Play online games by the measurement table、North Africa、4,5555 adults in 31 countries in Asia and Latin America's personal water safety situation。Research indicates，Among the 3 billion adults represented by the sample in 2021，436 million people are unsafe with water，accounting for 14.2%of the general investigation population。Where，African countries south of Sahara are the highest unsatisfactory water use。

 

Yang and others said，There is no fixed、A single water unsafe social characteristics。Researchers discovered，Low -income people living in the suburbs of urban areas are most likely to have problems with water use。People usually think，Women should bear more housework and save daily water for the community，Therefore, their water safety rate is lower than men，However, the research results show，Among 31 countries，Bisexual water bet365 live casino games safety rates in 25 countries are basically similar。

 

Yang and others think，Hundreds of millions of people around the world have reduced the quality of life due to the problem of unsafe water use。The population characteristics of this group、Regional and socio -economic structures different。I hope that more experts will jump out of the dimensions of water and water conservancy facilities in the future to study the problem of unsafe water use，and combined with food、Safety of key resources such as transportation，Further understand the population characteristics of the global water resources crisis。other，Measurement of the water experience of individuals and families is also conducive to decision makers to formulate corresponding intervention measures for specific conditions，Effectively serving the most affected disadvantaged group。
