Re: Call for Papers for the 1st IWA Non-Sewered Sanitation Conference (Closing date for Call: 15 December 2019)

I'm wondering about yet another term and accronym: This conference is called "Non-sewered sanitation" (NSS). Is there any difference to the term Fecal Sludge Management (FSM) which has become so popular in recent years? Is one term overarching the other, or should NSS replace the term FSM?

What do you all think?

In my understanding, FSM is a subset of NSS, which also includes other alternatives like composting toilets, eco-san toilets, settled and condominium sewers.

Do you mean to question the need for another conference when we already have FSM conference?
