"A scarcity of quality seed remains a fundamental bottleneck in the effort to improve food security throughout sub-Saharan Africa. The first step therefore is to make clean quality planting materials available to farmers. Currently pests and diseases are major constraints to yam production in West African. Farmers often have to plant poor quality material that is often already infected, leading to low yields of this regionally important crop. Yams are a staple food in West Africa and yet over the years several varieties have been lost to a combination of pests and diseases. There have been several efforts to improve seed yam quality. These attempts have failed due to lack of sustainability and/or because of the adaptation of inferior technologies. We have found a project which can overcome many of these obstacles and this is why we were keen to invest in capacity building this promising work."This initiative is led by the Missionary Sisters of the Holy Rosary. Their Diocesan Development Services have been working at a small scale in Kogi State, Nigeria, since 2002, promoting an improved yam multiplication technique, known as the mini-sett approach, to more efficiently produce larger amounts of disease-free planting material. The mini-sett approach was developed through research including that supported by DFID's Crop Protection Programme.
