The RUNRES project: Establishing a nutrient loop to improve city region food system resilience

RunRes is a project aiming for poverty alleviation through establishing nutrient loops to improve city region food system resilience.

It is based in Ethiopia, Rwanda, the DRC and South Africa. The project Leader is Prof Johan Six, Professor for Sustainable Agroecosystems, ETH Zürich. The funding is from the Swiss Agency for Development and Cooperation (SDC). It has recently been launched in Rwanda, DRC and South Africa.

Re: The RUNRES project: Establishing a nutrient loop to improve city region food system resilience

Dear Chris,

Thanks for sharing information with us about this very important project.

In addition to "making fertilizers" with urine and feces, I would like to suggest that much of the urine can be recycled unprocessed in urban agriculture, especially via exhuberant tropical plants, like banana plants. Based on G. Sridevi's application of 63 liters of human urine to each banana plant, I would propose linking the urinal for each person to a set of 6 banana plants, via a perforated hose buried 10 cm below the surface of the soil. One part of the puzzle could be the adaptation of banana plants to tubs made from old tires on the terrace of the roof.

Please let me know if I can be of any help on this.

Best wishes,
Chris Canaday

Hello Chris Buckley and Johan,

thank you for putting this information on the forum. Here the forum really proves its value, otherwise we would never have learned that you work here in Rwanda on a similar approach of closing the loop between sanitation and agriculture/nutrition. I know this is not your only focus but it is the one where we can interlink.

Who is 'we'? We are WASAC (Water and Sanitation Corporation) responsible in Rwanda for water and sanitation services, and specifically the SPIU (Single Project Implementation Unit) which is currently implementing a donor funded (loan + grant) water & sanitation program in Kigali, in six satellite cities and in eight rural areas. As part of the program we are just discussing the piloting of vermi-culture as a way of making sanitation more sustainable by closing the loop between sanitation and agriculture bringing the processed solids and the treated effluent back onto the fields instead of flushing them into rivers and lakes (more untreated than treated).

Please have a look at the thread where we discuss operational and technical details of our endeavors. We had already a first meeting with reps of RUNRES at the WASAC office yesterday (04.10.19) and hope for more collaboration while we both implement our programs.
