Quality seed is one of the most important farm inputs. The Ituri province, in northeastern Democratic Republic of Congo (DRC), faces enormous challenges in implementing a coherent formal seed sector, an essential gage for seed quality. This study aimed at diagnosing the Ituri seed value chain to propose improvements at all levels. Data collection was conducted using focus group discussions and direct interviews with key players at all levels, household surveys across the province, and a review of seed intervention programme reports, farm visit reports and other literature. Results showed that the seed system in the northeastern DRC is mainly informal due to several socioeconomic and technical factors. Less than a third of crops in the region had a formal seed delivery system. The cash flow in the seed sector was high owing to high seed demands from humanitarian organizations and farmer support structures, estimated at ∼1.5 million US$ in 2022 for the top three commercial seed commodities (common beans, maize and peanuts). However, the province seed production capacity through formal pathway is low (only ∼35 and 69% of the demands for common bean and maize, respectively, are covered by local productions), meaning that the seed demand is met either through importation or fraudulent conversion of farmer-saved seed. Due to lack of technical capacities, Ituri seed multipliers mainly produce open pollinated and synthetic varieties, while hybrids are imported from neighbouring countries. The lack of functional breeders in the provincial seed production chain, disproportionately low seed multipliers-to-distributors ratio, the weakness of the seed certification and regulation services, the border porosity, poor coordination among actors, and low awareness of farmers on seed qualities and advantages of using certified quality seed are the main structural and functional factors hindering the well-functioning of northeastern DRC seed system. This study provided an insight on the characteristics, stakeholders and challenges facing the seed sector in northeastern DRC and proposed an action plan for its improvement.

Neglected and underutilized crop species (NUCS) are valuable sources of food and income for several rural households in the eastern Democratic Republic of Congo (DRC). A thorough understanding of their diversity, uses, socio-economic roles, and factors for their neglect would be necessary for guiding promotion efforts. This study was conducted in two steps: (1) interviews with rural households involved in NUCS production and trade, and (2) greenhouse characterization of the two most popular NUCS′ morphotypes, African nightshade and amaranth, from Walungu and Kabare territories, eastern DRC. About 19% of farmers of the entire study area were involved in NUCS production. We identified 22 and 23 NUCS used in Kabare and Walungu territories, respectively. These species belonged to 19 botanical families, among which Solanaceae (∼24% in Walungu and ∼11 in Kabare) and Fabaceae (8% in Walungu and 11% in Kabare) were the most dominant families. They were of different ranges: grasses and herbs (62%), shrubs (20%), thorns (2%), and trees (16%). These species were used whether for nutritional (60%), medicinal (7%), or both nutritional and medicinal values (33%). NUCS' market value was low, and thus, discouraged further investment in their farming. The seed delivery system was informal, dominated by farmer-saved seed, seed from local markets, and farmer seed exchange. Characterization experiment for the most popular leafy NUCS showed differences among collected morphotypes for most traits, with some local genotypes outperforming exogenous commercial varieties. Supply of quality seed, training of farmers on the most appropriate cropping system, processing technologies, increased consumer awareness, linking research to policy, and increasing market opportunities for smallholder farmers are strategies for promoting wide use of these crops in eastern DRC.
