联合国报告：全球四分之一人口仍缺乏安全饮用水

Group 1 - The report by WHO and UNICEF indicates that despite progress in drinking water and sanitation over the past decade, one-quarter of the global population (approximately 2.1 billion people) still lacks access to safe drinking water [1][2] - Since 2015, the global coverage of safely managed drinking water has increased from 68% to 74%, yet around 2.1 billion people remain without safe drinking water, including 106 million who directly consume untreated surface water [1] - The report categorizes drinking water safety management into five levels, with the highest level being access to safe drinking water without fecal and chemical contamination [1] Group 2 - The report also highlights the status of global sanitation services, noting that the coverage of safely managed sanitation services has risen from 48% to 58% since 2015, but 3.4 billion people still lack safe sanitation services [2] - Among those lacking sanitation, 354 million are forced to practice open defecation, and 1.7 billion lack basic household sanitation facilities, with 611 million having no access to any sanitation facilities [2] - The likelihood of people in the least developed countries lacking basic drinking water and sanitation services is more than double that of other countries, with the probability of lacking basic sanitation facilities being more than three times higher [2] Group 3 - WHO warns that inadequate drinking water, sanitation, and personal hygiene services may expose billions to greater health risks [3] - UNICEF emphasizes that when children lack access to safe drinking water and sanitation facilities, their health, education, and future development are at risk [3] - Both WHO and UNICEF call for accelerated action to achieve the UN's 2030 Sustainable Development Goals related to providing water and sanitation for all and managing them sustainably [3]
