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

This report details a study tour conducted from November 12 to 16, 2012, in the Aguié department of the Maradi region in Niger. Organized by EAA and funded by the Stockholm Environment Institute (SEI) as part of the Triple Green project, the tour aimed to train a working group of government officials and researchers on 'productive sanitation' (AP). The mission focused on the use of hygienized human urine (Takin Ruwa) and feces (Takin Boushashé) as ecological fertilizers, visiting pilot sites in Gazaoua and Madaoua to observe application methods, yield comparisons, and community acceptance.

• The implementation of productive sanitation in the villages of Saja Manja and Maifarou initially faced resistance from producers, which was overcome through meetings with religious and customary leaders who confirmed that using human excreta in agriculture is not forbidden by religion.
• Hygienization of human waste is achieved through time and storage without additives: urine is stored in hermetically sealed 25-liter containers for 30 days to destroy pathogens, while feces are treated in EcoSan latrines for 6 months (dry latrines) or 12 months (composting latrines).
• Takin Ruwa (hygienized urine) is applied to the soil rather than directly to plants, typically in a hole or furrow approximately 10 cm from the plant, followed by intensive watering to prevent ammonia evaporation and root damage.
• Comparative tests in Saja Manja and Maifarou showed that crops fertilized with Takin Ruwa achieved significantly higher yields than those treated with urea or NPK. For example, in Saja Manja, a 1/4 hectare of millet treated with Takin Ruwa yielded 25 bottles (162.5 measures), compared to 7 bottles (45.5 measures) for the urea-treated plot.
• Takin Ruwa has acquired economic value in some villages, being stored for profit and sold in 25-liter containers for prices ranging from 500 FCFA in Saja Manja to 1,500 FCFA in Maifarou.
• To ensure consumer safety, the World Health Organization (WHO) recommends a one-month delay between the application of urine and the harvest of raw vegetables; however, in Aguié, a two-week delay was considered sufficient due to the hot climate.
