Rapport voyage d’étude sur Aguié tenue du 12 au 16 Novembre 2012

The report details a study tour in the Aguié department, Niger, focused on 'productive sanitation' (EcoSan). It describes the use of hygienized human urine (Takin Ruwa) and feces (Takin Bussasché) as agricultural fertilizers. Key findings include significant yield increases in millet and peppers compared to chemical fertilizers, the importance of community engagement with religious and traditional leaders to overcome cultural resistance, and specific technical protocols for the collection, storage, and application of ecological fertilizers to ensure safety for producers and consumers.

• Initial community resistance to using human excreta for agriculture was overcome through meetings with religious and traditional leaders who confirmed that such practices are not forbidden by religion, as well as by highlighting the effectiveness of nearby fields where people naturally relieve themselves.
• Hygienization of ecological fertilizers is achieved through time and storage: urine is stored in sealed 25-liter containers for 30 days, while feces require 6 months of storage in dry latrines or 12 months in composting latrines to eliminate pathogens.
• Comparative tests showed that crops fertilized with Takin Ruwa (hygienized urine) achieved higher yields than those treated with urea or NPK. In Saja Manja, a 1/4 ha plot of millet treated with TR yielded 25 bottles (162.5 measures) compared to 7 bottles (45.5 measures) for the urea plot; in Maï Farou, a TR plot yielded 40 bottles (300 measures) against 25 bottles (185.5 measures) for the NPK plot.
• For pepper crops in Maï Farou, the use of Takin Ruwa resulted in a yield of 8 bags for 250 plants, whereas both urea and manure treatments resulted in only 2 bags for the same number of plants.
• To ensure safety, Takin Ruwa must be applied to the soil (via a hole or furrow) rather than directly on plants and followed by intensive watering. For raw vegetables, a minimum delay of two weeks between application and harvest is considered sufficient in Niger's hot climate, though the WHO recommends one month.
• Hygienized urine has become a valuable commodity in some villages, with reported sale prices for 25-liter containers ranging from 500 FCFA in Saja Manja to 1500 FCFA in Maï Farou.
