Traditional closed-loop sanitation systems in peri-urban and rural Afghanistan: a SWOT analysis

The closed-loop-sanitation-system (CLSS), or sustainable sanitation system, has accelerated in recent years and been successfully implemented in many parts of the world. This study explored the strengths, weaknesses, opportunities, and threats (SWOT) of the traditional CLSS (T-CLSS) in both peri-urban and rural contexts within three different provinces in Afghanistan, the first study of its kind in this country. Participatory research tools such as transect walks, focus group discussions, and interactive workshops have been applied to assess the SWOT components of T- CLSS. The results show that T-CLSS is practiced historically in both peri-urban and rural areas by different generations using local and traditional knowledge, skills and technologies. Socio-cultural acceptance of the system is considered as one of the strengths in both rural and peri-urban areas. It is highly recommended that the feasibility of improved CLSS be assessed and implemented in the light of the T-CLSS system
