“…The marginalization and subsequent erosion of over twenty yam species recorded during the study is a source of concern as yam is a commonly cultivated food crop in the area. This incidence of serious genetic erosion of yams is also corroborated by (Aboagye et al, 2015). Yam is regarded as one of the few important staple crops in Ghana.…”

The study examined Neglected and Underutilized Crop Species (NUCS) in two agro-ecologically diverse zones in Ghana with the view to highlighting the varieties, their important benefits and uses among rural households in the Upper Afram and Upper Dayi basins. Qualitative data was gathered from two hundred and seventy-one (271) respondents in six farming communities within the middle belt of Ghana through focused group discussions, interviews and questionnaires. A total of one hundred and twelve (112) NUCS were identified during the study. The diversity of NUCS in the study areas provide an indication of the existence of a valuable plant resource that can be exploited to help address food inadequacy challenges among rural households within the Upper Afram and Upper Dayi basins. Apart from their use as food, medicine, dyes, soap making, fuel wood and livestock feed, some NUCS found within the study basins play very important roles in the cultural practices and traditional ceremonies. These findings demonstrate the untapped potential of NUCS in addressing food and nutritional insecurity among rural households in the country. Institution of regular NUCS focused food fairs at the local (village), district and regional levels to promote local dishes prepared from the indigenous food crops; as well as increased NUCS related research are recommended.

“…Example 1: Diversity and production of yams in Southern Ghana (Aboagye et al 2015) This study was carried out in four communities in Ghana to survey the number of yam species and varieties cultivated per household, to identify the preferred and endangered ones, challenges facing yam farmers, and to develop strategies for sustainable yam production. In each village, the four-square method was used to record: name of variety, species, early of late maturity, and extent of distribution.…”

The CGIAR Research Program on Roots, Tubers and Bananas (RTB) is a partnership collaboration led by the International Potato Center (CIP) implemented jointly with the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT), the International Institute of Tropical Agriculture (IITA), and the Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD), that includes a growing number of research and development partners. RTB brings together research on its mandate crops: bananas and plantains, cassava, potato, sweetpotato, yams, and minor roots and tubers, to improve nutrition and food security and foster greater gender equity, especially among some of the world's poorest and most vulnerable populations.

BackgroundYam ( Dioscorea spp .) is cultivated in many villages of DR Congo as a means to sustain food security and alleviate poverty. However, the extent of the existing diversity has not been studied in details thus, considered as an orphan.MethodologyA survey covering 540 farmers in 54 villages was conducted in six major yam growing territories covering three provinces in DR Congo to investigate the diversity, management and utilization of yam landraces using pre-elaborate questionnaires.ResultsSubject to synonymy, a total of 67 landraces clones from five different species were recorded. Farmers’ challenges limiting yam production were poor tuber qualities (69%), harvest pest attack (7%), difficulty in harvesting (6%), poor soil status (6%). The overall diversity was moderate among the recorded yam germplasm maintained at the household level (1.32) and variability exist in diversity amongst the territories and provinces. Farmers’ in territories of Tshopo and Mongala provinces maintained higher level of germplasm diversity (2.79 and 2.77) compared to the farmers in territories of Bas-Uélé (1.67). Some yam landraces had limited abundance and distribution due to loss of production interest in many villages attributable to poisons contained hence, resulting in possible extinction. Farmers’ most preferred seed source for cultivation were backyard (43%) and exchange with neighboring farmers (31%) with the objective of meeting food security and generating income. In villages where yam production is expanding, farmers are relying on landraces with good tuber qualities and high yield even though they are late maturing.ConclusionThis study revealed the knowledge of yam genetic diversity, constraints to production and farmers’ preferences criteria as a guide for collection and conservation of yam genetic resources for yam improvement intervention.
