Provision of sustainable sanitation in emergency situations: role of ecosan

Publication year

This paper describes the potential of ecological sanitation (ecosan), and in particular of urine-diversion dehydrating (UDD) toilets, to provide sustainable excreta disposal in emergency situations in low-income countries. Three case studies of emergency sanitation were analysed: El Salvador (hurricane), Afghanistan (civil war) and Pakistan (earthquake). The analysis of these case studies has shown that the systems implemented in the long-term phase of the emergency were sometimes more sustainable than what was in place before the emergency occurred.
