The Warrantage system is based on the establishment of farmer-based cooperatives or producers’ associations and village savings-credit associations which provide farmer’s access to microcredit.
Mr Seydou Boubacar, a 39-year-old-farmer from Bokki, a village 60 kms to the south of Niamey, practices the microdosing technique on his farm. At first, in 2002, he experimented with this technique on a 0.5 ha patch with millet, and got a yield of 570 kg. Previously he had grown millet on 1.5 ha and got just 450 kg. This astonishing increase on just one-third the land speaks volumes!
Another initiative through Project Intrants: was YARBIC/CAPTALISATION with the financial support of the Belgium Cooperation Agency (through FAO) which involved not only Niger but also Burkina Faso
Training, extension and promotion facilitated under a consortium of donors, working with nine international NGOs and a number of local NGOs
Wide scale testing of the microdosing (17 kg Nitrogen ha-1) concept initiated across multiple locations in southern Zimbabwe through relief and recovery programs.
FAO also funded another scaling up effort in Niger from 2003-2006. This was in partnership with several NGOs and the International Center for Tropical Agriculture / Tropical Soil Biology Fertility (CIAT/TSBF), within the decision support system project of ICRISAT
Undertaken within the CGIAR Challenge Program on Water and Food (CPWF), which is now part of the CGIAR Research Program on Water Land and Ecosystems
Scaling out of microdosing and Warrantage through Conseil Ouest et Centre Africain pour la Recherche et le Développement Agricoles / West and Central African Council for Agricultural Research and Development (CORAF/WECARD) Funded by: African Development Bank (AfDB) in Also scaled out fother in Mali, Niger, Senegal and Burkina Faso.
