Water is a scarce resource, especially in the arid plains of Inner Mongolia.
In 2003, the Stockholm Environment Institute in collaboration with a local district of Ordos started to implement a project of eco-sanitation and tested dry toilets. But this initiative came to an end in 2010.
Arno Rosemarin and Guoyi Han explained in a short article the reasons why this poject was not continued.
