Ladahi toilets are one of the cleanest toilets I have ever been to, even though its just a hole in a shack. There is no water, just mud and soil. The odour is bearable, there isn’t any really horrid smell compared to those water sewage septic toilets.
In other places in the Himalayas, instead of mud, they use millet husk or wheat husk to cover up your daily soils. and the pigs will feast under the shack. Just in case you are wondering, yes people do eat those pigs during festival times.
