Farming practices, varietal preferences, and land suitability analyses for yam production in Eastern D.R. Congo: implications for breeding initiatives and food sovereignty
Yam (Dioscorea spp.) is a key tuber crop in sub-Saharan Africa (SSA) with huge potential for poverty alleviation, food sovereignty, and nutrition security. Exploiting its full potential requires that factors holding it down are understood and mitigated. This study, conducted between May and July 2022 and 2023, assessed yam farming practices, varietal preferences, and land suitability in the Eastern Democratic Republic of Congo (DRC). We interviewed 765 smallholder farmers within four agro-ecological zones (AEZ) to assess the sociocultural, agronomic, varietal, and biophysical factors affecting yam production. Land suitability analyses were conducted using the Analytic Hierarchy Process (AHP) to identify areas suitable to extensive yam production and to cluster environments that could optimize yam varietal selection and testing. Results showed that yam is mainly cultivated by women in eastern DRC (70%). The seed delivery system is informal, relying primarily on farmer-saved seeds and farmer-seed exchanges (74.9%). Soil depletion (68.3%), limited access to high-quality seeds (54.5%), youth disengagement in yam value chain (50.3%), insect pests (17.9%), and short tuber shelf-life (65.8%) were, respectively, the main ecological, agronomic, sociocultural, biological, and tuber quality factors hindering yam production in eastern DRC. However, the perceived importance of most factors significantly varied with farmer gender and age categories. A multitude of varietal traits was used to assess yam varieties in eastern DRC, of which the tuber taste (59%) was the most valued trait regardless of gender and age categories, though it had highest scores among middle-aged adult women. Land suitability analyses discriminated five clusters; the most significant part of the region falling under suitable (27%), highly suitable (24%), and very highly suitable classes (37%). We further discussed how breeding initiatives for delivering yam varieties, suiting local producers’ and end-users’ needs, could unlock the crop’s potential for enhancing food security and wealth creation in eastern DRC. The land suitability map from this study is a valuable decision-making tool in defining priority areas for extensive yam production and varietal selection and testing. This study provided valuable insights on factors affecting yam production and suggested yam breeding as a backbone of a holistic approach seeking to address challenges faced in unlocking the potential for yam production in eastern DRC
Current Practices and Prospects of Climate-Smart Agriculture in Democratic Republic of Congo: A Review
peer reviewedClimate-smart agriculture (CSA) is one of the innovative approaches for sustainably increasing the agricultural productivity, improving livelihoods and incomes of farmers, while at the same time improving resilience and contributing to climate change mitigation. In spite of the fact that there is neither explicit policy nor practices branded as CSA in Democratic Republic of Congo (DRC), farmers are utilizing an array of farming practices whose attributes meet the CSA criteria. However, the intensity, distribution, efficiency, and dynamics of use as well as the sources of these technologies are not sufficiently documented. Therefore, this review paper provides a comprehensive evidence of CSA-associated farming practices in DRC, public and private efforts to promote CSA practices, and the associated benefits accruing from the practices as deployed by farmers in the DRC. We find evidence of progress among farming communities in the use of practices that can be classified as CSA. Communities using these practices are building on the traditional knowledge systems and adaptation of introduced technologies to suit the local conditions. Reported returns on use of these practices are promising, pointing to their potential continued use into the future. While progressive returns on investment are reported, they are relatively lower than those reported from other areas in sub-Saharan Africa deploying similar approaches. We recommend for strategic support for capacity building at various levels, including public institutions for policy development and guidance, extension and community level to support uptake of technologies and higher education institutions for mainstreaming CSA into curricula and training a generation of CSA sensitive human resources
Le système de production de la poule locale contraint son développement au Sud-Kivu, Est de la République Démocratique du Congo
Objectif : Cette étude a été menée envue de caractériser le système de production et de reproduction de la poule locale dans trois zones agro-écologiques du Sud-Kivu d’Avril jusqu’en Décembre, 2017. Méthodologie et résultats: Une enquête transversale a été menée à l’aide d’une interview auprès de 360 éleveurs répartis dans 3 zones agro-écologiques dont la haute, moyenne et basse altitude. Les principaux résultats trouvés indiquent que ces élevages sont gérés par les hommes, ayant un objectif tourné vers le marché (90,28%), comptent 24,38 poules qui sont élevés en divagation (94,17%) sans logement spécifique (81,11%). Les poules reçoivent une supplémentation alimentaire (65,28%) et un complément vitaminique (25,83%). La pseudopeste aviaire est la maladie la plus fréquente (89,72%), suite à l’absence de la vaccination (96,67%), les éleveurs recourent à la pharmacopée traditionnelle (77,5%). Chaque poule donne 13 œufs par cycle de ponte pour 2,96 cycles par an. 70,37% des œufs pondus sont incubés pour un taux d’éclosion de 84,50% et un taux de sevrage de 57,25%, intervenant à 2,52 mois après éclosion. Les épidémies et la prédation sont les principales contraintes auxquelles font face les éleveurs de la poule locale en plus du manque d’appuis par les services étatiques. Conclusion et application des résultats: Quoique cet élevage soit une activité secondaire et selon les techniques de production traditionnelle avec des faibles performances, il reste primordiale dans l’économie des familles rurales et mérite une attention particulière visant son amélioration. Une stabulation ainsi qu’une alimentation équilibrée permettraient d’accroitre la production et réduire les risques de perte des poules.Mots clés : Elevage, zones-agro écologiques, Contraintes, poule locale, Sud-Kivu
Seed delivery system in northeastern Democratic Republic of Congo: characteristics, stakeholders mapping and challenges towards building a well-functioning seed system under humanitarian and security crises
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.</p

Seroprevalence of anti-SARS-CoV-2 antibodies and risk of viral exposure among healthcare workers in the South Kivu province, eastern Democratic Republic of the Congo: a cross-sectional study
Objectives Healthcare workers (HCWs) are on the frontline of combating COVID-19, hence are at elevated risk of contracting an infection with SARS-CoV-2. The present study aims to measure the impact of SARS-CoV-2 on HCWs in central sub-Saharan Africa.Setting A cross-sectional serological study was conducted at six urban and five rural hospitals during the first pandemic wave in the South Kivu province, Democratic Republic of the Congo (DRC).Participants Serum specimens from 1029 HCWs employed during the first pandemic wave were collected between August and October 2020, and data on demographics and work-related factors were recorded during structured interviews.Primary and secondary outcome measures The presence of IgG antibodies against SARS-CoV-2 was examined by ELISA. Positive specimens were further tested using a micro-neutralisation assay. Factors driving SARS-CoV-2 seropositivity were assessed by multivariable analysis.Results Overall SARS-CoV-2 seroprevalence was high among HCWs (33.1%), and significantly higher in urban (41.5%) compared with rural (19.8%) hospitals. Having had presented with COVID-19-like symptoms before was a strong predictor of seropositivity (31.5%). Personal protective equipment (PPE, 88.1% and 11.9%) and alcohol-based hand sanitizer (71.1% and 28.9%) were more often available, and hand hygiene was more often reported after patient contact (63.0% and 37.0%) in urban compared with rural hospitals, respectively. This may suggest that higher exposure during non-work times in high incidence urban areas counteracts higher work protection levels of HCWs.Conclusions High SARS-CoV-2 seropositivity indicates widespread transmission of the virus in this region of DRC. Given the absence of publicly reported cases during the same time period at the rural sites, serological studies are very relevant in revealing infection dynamics especially in regions with low diagnostic capacities. This, and discrepancies in the application of PPE between urban and rural sites, should be considered in future pandemic response programmes
