India and China have made notable progress towards reaching the Millennium Development Goals (MDGs) for safe drinking water. The findings of the study are published in the journal Nature Sustainability.// The United Nations Millennium Development Goals (MDGs) attempted from 2000 to 2015 produced mixed and debatable results. But there was at least one clear MDG victory: safe drinking water.
‘Economic development in India and China is the key to achieving Millennium Development Goals (MDGs) for safe drinking water.’MDG Target 7C sought to halve, by 2015, the ratio of the world's people without sustainable access to safe drinking water and basic sanitation. In this, the drinking water target was reportedly realized in 2010. No such global target on drinking water had ever before achieved.

Research led by The University of Tokyo Institute of Industrial Science (IIS) traced why this monumental achievement was accomplished when others failed. It also delved deeper into what defined success, and if the factors behind it could be reproduced for achieving other socioeconomic goals.
"Achieving MDG Target 7C-Water was definitely a success," study senior author Taikan Oki at IIS says. "However, this achievement is not cut-and-dry. We found that comparatively modest goals along with rapid urbanization, especially in China, and rural development in India, were major enablers of the success."
Global targets for accessible drinking water have varied widely, from 100 percent coverage to much lower benchmarks. The researchers looked at previous targets and reports. They found considerable variation in definitions of safe drinking water. Some emphasized lack of contamination, while others focused on factors such as the amount of available water or distance to water collection. This variance may have led to different interpretations of results.
They also found that the MDG period coincided with massive rural-to-urban migration in China, along with both rural and urban development in India. These were critical in expanded drinking water coverage, as the two countries account for roughly one-third of the world's population. China's urban population more than doubled during the period.
The Sustainable Development Goals (SDGs) have now taken over the tasks of both expanding on the MDGs and trying to accomplish those that are still outstanding.
