Situated in the Northeast of the country, the district of Lushoto is part of the so called highlands of Tanzania where potatoes are traditionally grown. Due to heat and lack of resilient potato varieties, farmers would lose all the crop especially when they grow the local variety called Kidinya which is extremely susceptible to Late Blight disease. To address these issues, the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), initiated a study aimed at developing more resilient potato varieties that can grow in both long and short rainy seasons and give higher yields. The study, initiated in 2013, was led by the International Potato Center (CIP) in partnership with Selian Agricultural Research Institute (SARI), Lushoto District Agriculture, Irrigation and Livestock Cooperatives Office (DAICO), YARA Tanzania Limited, Japan International Cooperation Agency (JICA), local Non-Governmental Organizations (NGOs) and Lushoto farmers.
