The symposium (2014) focused on the challenges of crop production faced by farmers in the Sahel region. The presentation covers a three-year fertilizer micro dosing (MD) project that was combined with rainwater harvesting (RWH). The techniques are assessed in terms of effects on crop production and family income. It also explores the “warrantage” or inventory credit system where harvested crops are stored and used as collateral to access loans and credit. With improving crop varieties, MD and RWH can increase yields up to 200%. There is no evidence that the process caused land degradation or yield decline, suggesting long term sustainability.
