Indigenous knowledge-based evaluation of Ambachi tuberous plant as a future famine food crop for Darfur State, Sudan

Abstract

Malnutrition and associated diseases are major challenges in the semi-arid Sahelian zone of Africa, where rainfall is <600 mm per annum. The objective of this study was to document indigenous knowledge on the significance and management of Ambachi (Dioscorea hispida) in East Darfur State, Sudan. A total of 101 respondents was interviewed using a semi-structured questionnaire in Bahr Alarab Locality, located in East Darfur State. Additionally, key informants and group discussions were held with local leaders to supplement data collection. The results revealed that Ambachi plant is fairly plentiful in East Darfur state, and grows naturally in the wild. All respondents were knowledgeable about Ambachi plant’s appearance, growth cycle, usage and storage processes. Generally, Ambachi tubers are stored in various types of natural and synthetic containers, and for varied periods of time. However, up to 78% of the respondents reported Shawwal (made of plastic material), as the most preferred container for storage of dry tubers. Virtually all households (99%) attested to consuming Ambachi-based foods particularly during famine periods. Up to 98% of Ambachi plant tubers are soaked before cooking to remove the bitter taste; and two thirds of interviewees were familiar with the cooking process of Ambachi foods. Lastly, Ambachi plant tubers are tradable in different local markets across the region; although it was mainly sold in Abu matareg market located in Bahar Alara locality.
