Improved sanitation has been shown to have great impacts on people's health and economy. However, the progress of achieving the Millennium Development Goals (MDGs) on halving the proportion of people without access to clean water and basic sanitation by 2015 has thus far been delayed. One of the reasons for the slow progress is that policy makers, as well as the general public, have not fully understood the importance of the improved sanitation solutions. This paper, by gathering relevant research findings, aims to report and discuss currently available evidence on the economic aspects of sanitation, including the economic impacts of unimproved sanitation and the costs and economic benefits of some common improved sanitation options in developing countries.
DATA USED IN THIS PAPER WERE OBTAINED FROM DIFFERENT INFORMATION SOURCES: international and national journal articles and reports, web-based statistics, and fact sheets. We used both online search and hand search methods to gather the information.
Scientific evidence has demonstrated that the economic cost associated with poor sanitation is substantial. At the global level, failure to meet the MDG water and sanitation target would have ramifications in the area of US$38 billion, and sanitation accounts for 92% of this amount. In developing countries, the spending required to provide new coverage to meet the MDG sanitation target (not including program costs) is US$142 billion (US$ year 2005). This translates to a per capita spending of US$28 for sanitation. Annually, this translates to roughly US$14 million. The evidence complied in this paper demonstrates that investing in sanitation is socially and economically worthwhile. For every US$1 invested, achieving the sanitation MDG target and universal sanitation access in the non-OECD countries would result in a global return of US$9.1 and US$11.2, respectively.
Given the current state of knowledge, sanitation is undeniably a profitable investment. It is clear that achieving the MDG sanitation target not only saves lives but also provides a foundation for economic growth.
改善卫生条件已被证明对人们的健康和经济有重大影响。然而,到2015年将无法获得清洁水和基本卫生设施的人口比例减半这一千年发展目标(MDGs)的进展迄今已被推迟。进展缓慢的原因之一是政策制定者以及普通公众尚未充分理解改善卫生设施解决方案的重要性。本文通过收集相关研究结果,旨在报告和讨论目前关于卫生设施经济方面的现有证据,包括未改善的卫生条件的经济影响以及发展中国家一些常见的改善卫生设施选项的成本和经济效益。

科学证据表明,与卫生条件差相关的经济成本巨大。在全球层面,未能实现千年发展目标的水和卫生目标将产生高达380亿美元的影响,其中卫生设施占这一数额的92%。在发展中国家,为实现千年发展目标的卫生设施目标提供新的覆盖范围所需的支出(不包括项目成本)为1420亿美元(2005年美元)。这相当于人均卫生设施支出28美元。每年,这大约相当于1400万美元。本文汇总的证据表明,投资于卫生设施在社会和经济上是值得的。在非经合组织国家,每投资1美元,实现卫生设施千年发展目标和普及卫生设施将分别带来9.1美元和11.2美元的全球回报。
鉴于目前的知识状况,卫生设施无疑是一项有利可图的投资。显然,实现千年发展目标的卫生设施目标不仅能挽救生命,还为经济增长奠定基础。
