This case study is based in Africa, where cassava is a key food security crop, and focuses on the gravity of the threat that cassava brown streak disease (CBSD) poses to resource-poor cassava growers. The goal of the study is to illustrate how providing information on disease spread can help not only growers who plant infected material but also other growers in the region. Planting infected cuttings can negatively impact cassava production and intensify hunger in the region. The case also highlights the role that non-governmental organizations (NGOs) and research organizations play in multiplication and dissemination of cassava cuttings and how this activity can be coupled with providing information on disease management. Both cassava mosaic disease (CMD) and CBSD can cause devastating losses depending on the susceptibility of the variety planted and the time of infection.
