En Afrique subsaharienne, les petits exploitants agricoles ruraux ont difficilement accès aux connaissances et informations actualisées afin d’améliorer leur revenu. Pour renforcer l’apprentissage collectif au sein des acteurs des chaînes de valeur du riz local blanc et étuvé, la vidéo et la radio ont été utilisées de façon participative. La présente étude visait à comprendre l’influence de cet apprentissage collectif sur (i) le changement des pratiques des transformations et (ii) la qualité du riz local. Des interviews et suivis hebdomadaires ont été réalisés entre 2009 et 2018 au sud et nord du Bénin auprès de 240 transformateurs choisis aléatoirement. Des échantillons de riz ont été également collectés pour des analyses de qualité au laboratoire. L’analyse des données a été faite avec les tests t de Student, Wilcoxon, ANOVA, et le modèle de régression de Poisson. Les résultats ont montré une amélioration des pratiques de 14% ; 23% et 58% respectivement dans les villages contrôles, radio et vidéo. Dans le processus d’amélioration des pratiques, les transformateurs ont renforcé leur créativité en développant des technologies appropriées à leur environnement ; ce qui a eu un impact positif sur les qualités physiques et de cuisson du riz. Dans un contexte de pauvreté, d’insécurité alimentaire, de ruralité et d’analphabétisme, l’apprentissage collectif par la vidéo et la radio locale se révèle être une opportunité pour le renforcement du système d’innovation agricole.   English title: Smallholder farmers at inclusive school: Lessons learnt from collective  learning through video and radio on local rice processing in Benin In sub-Saharan Africa, rural smallholder farmers have limited access to timely and up-to-date knowledge and information to improve their incomes. To strengthen collective learning among rice sector’ stakeholders, videos and radio were participatory used. This study aims to assess the impact of this collective learning on (i) changing rice processors practices and (ii) the quality of local rice. Interviews and weekly follow-ups were conducted between 2009 and 2018 in southern and northern Benin with 240 randomly selected rice processors. Rice samples were also collected for quality analysis in the laboratory. Data analysis was done with Student's t-tests, Wilcoxon, one-way ANOVA, and the Poisson regression model. The results showed an improvement in rice processors practices of 14%; 23% and 58% respectively in control, video and radio villages. During the improvement of their practices, rice processors have increased their creativity by developing appropriate technologies to their environment; and this has positively impact on the physical and cooking qualities of the rice. In a context of poverty, food insecurity, rurality and illiteracy, collective learning through video and radio seems to be an opportunity to strengthen the agricultural innovation system, and a booster for change through adoption and adaptation of innovation.

In sub-Saharan Africa, development and dissemination of perceived new agricultural innovations dominate the development agenda yet hunger and poverty remain widespread. A conducive policy environment is essential to support these efforts. Despite that national policies are a critical component in the functioning of an agricultural innovation system, studies have often overlooked their relevance in farmers’ adoption of agricultural innovations. There is an urgent need to enhance understanding of how policies affect long-term adoption of agricultural innovations aimed at increasing productivity and incomes of smallholder farmers. This study utilises thematic content analysis to examine the extent of integration of Conservation Agriculture (CA) and coherence in Malawi’s national agricultural policies, and their implication for CA adoption among smallholder farmers.Results indicate that inadequate integration of CA in the National Agricultural Policy (NAP), coupled with a lack of coherence of agricultural department policies, undermines farmers’ CA adoption. While inadequate integration constrains resource allocation for supporting CA activities, lack of coherence of agricultural policies radiates conflicting and confusing agricultural extension messages to smallholder farmers. We argue that inadequate CA integration and incoherence of policies are institutional constraints which prevent farmers’ sustained adoption. To facilitate long-term adoption of CA among smallholders, there is need to: (1) strengthen CA integration in agricultural policies; (2) improve departmental coordination to enhance coherence of agricultural strategies and extension messages disseminated to farmers; and (3) strengthen government’s role in supporting multi-disciplinary research to generate and disseminate best practices capable of sustaining CA adoption.

Agricultural production in sub-Saharan Africa remains dependent on high inputs of human labor, a situation associated with direct exposure to daylight heat during critical periods of the agricultural calendar. We ask the question: how is the Wet-Bulb Globe Temperature (WBGT) going to be distributed in the future, and how will this affect the ability of smallholder farmers to perform agricultural activities? Data from general circulation models are used to estimate the distribution of WBGT in 2000, 2050 and 2100, and for high activity periods in the agricultural calendar. The distribution of WBGT is divided into recommended maximum WBGT exposure levels (°C) at different work intensities, and rest/work ratios for an average acclimatized worker wearing light clothing (ISO, 18). High WBGTs are observed during the two periods of the East African. In February to March, eastern and coastal regions of Kenya and Tanzania witness high WBGT values—some necessitating up to 75% rest/hour work intensities in 2050 and 2100. In August to September, eastern and northern Kenya and north and central Uganda are vulnerable to high WBGT values. Designing policies to address this key challenge is a critical element in adaptation methods to address the impact of climate change.

Abstract Cowpea is a grain legume of major importance in sub-Saharan Africa where it is cultivated by smallholder farmers on poor soils and production is often constrained by the parasitic weed Striga gesnerioides. Experiments were conducted to assess the potential of rhizobium inoculation in mitigating Striga infestation and increasing cowpea productivity. We tested under basal P application and artificial S. gesnerioides inoculation the impact of cowpea genotypes (G) (nine Striga-resistant and 11 Striga–susceptible genotypes) and bradyrhizobium inoculation (N) (two bradyrhizobium strains USDA3384 and IRJ2180A, and uninoculated control) on Striga dynamics and cowpea yield. Additional treatments included N supplied as urea (with and without), and no input (i.e., soil inherent N and P) that served as negative check. A first experiment was carried out in potted sterile soils in the screen house excluding addition of N-fertilizers. Significant G x N interactions were observed in counts of nodule (P = 0.012), Striga attachment (P < 0.0001) and emergence (P = 0.005), and cowpea shoot growth (P = 0.016). Cowpea nodulated poorly across host lines, Striga counts were the lowest for resistant varieties with no emerged plants. Rhizobial inoculants depressed Striga counts with consistent differences found across cowpea genotypes. Inoculation with IRJ2180A performed the best against Striga attachment in resistant genotypes, and its emergence in susceptible genotypes. In the field trial, nodule numbers were lowest in cowpea without inputs (P < 0.0001). The G x N interaction was significant in emerged Striga plants (P < 0.0001). Resistant genotypes were free of emerged Striga while for susceptible ones, Striga emergence was the highest without any input addition. Significant G x N interaction was observed in cowpea grain yield (P < 0.0001). Yield response to inoculation was most obvious for resistant genotypes inoculated with the strain IRJ2180A (P = 0.0043). The integrated use of Striga-resistant cowpea lines and elite bradyrhizobium inoculant under moderate application of P-based fertilizer could be a promising approach for mitigating Striga infestation and increasing productivity.

IntroductionThe COVID-19 pandemic has adversely affected health systems in many countries, but little is known about effects on health systems in sub-Saharan Africa. This study examines the effects of COVID-19 on hospital utilisation in a sub-Saharan country, Sierra Leone.MethodsMixed-methods study using longitudinal nationwide hospital data (admissions, operations, deliveries and referrals) and qualitative interviews with healthcare workers and patients. Hospital data were compared across quarters (Q) in 2020, with day 1 of Q2 representing the start of the pandemic in Sierra Leone. Admissions are reported in total and disaggregated by sex, service (surgical, medical, maternity and paediatric) and hospital type (government or private non-profit). Referrals in 2020 were compared with 2019 to assess whether any changes were the result of seasonality. Comparisons were performed using Student’s t-test. Qualitative data were analysed using thematic analysis.ResultsFrom Q1 to Q2, weekly mean hospital admissions decreased by 14.7% (p=0.005). Larger decreases were seen in male 18.8% than female 12.5% admissions. The largest decreases were in surgical admissions, a 49.8% decrease (p<0.001) and medical admissions, a 28.7% decrease (p=0.002). Paediatric and maternity admissions did not significantly change. Total operations decreased by 13.9% (p<0.001), while caesarean sections and facility-based deliveries showed significant increases: 12.7% (p=0.014) and 7.5% (p=0.03), respectively. In Q3, total admissions remained 13.2% lower (p<0.001) than Q1. Mean weekly referrals were lower in Q2 and Q3 of 2020 compared with 2019, suggesting findings were unlikely to be seasonal. Qualitative analysis identified both supply-side factors, prioritisation of essential services, introduction of COVID-19 services and pausing elective care, and demand-side factors, fear of nosocomial infection and financial hardship.ConclusionThe study demonstrated a decrease in hospital utilisation during COVID-19, the decrease is less than reported in other countries during COVID-19 and less than reported during the Ebola epidemic.

Background: Demonstration plots are widely used in the seed industry to create awareness and promote improved seed among smallholder farmers in sub-Saharan Africa. However, the magnitude of effects on farmers’ adoption behaviour is less known.Objectives: This study assessed the impact of demonstration plots and field days on farmers’ awareness, knowledge and use of the improved maize variety that was being promoted. The study also assessed the impact on maize yields and production.Method: A promotion campaign was mounted by a local seed company in eastern and western Uganda, where demonstration plots were established and field days were held for two seasons. These were aimed at augmenting effects of radio messages that were aired over the same period. We used quasi-experimental approaches to determine changes in farmers’ adoption behaviour towards a new maize variety, and the subsequent effects on productivity. Farm household data were collected at the baseline and midline from a sample of 2050 households.Results: The findings showed no effect on the proportion of farmers planting the promoted variety, the acreage or proportion of land planted with the promoted variety. This was not surprising as farmers’ awareness and knowledge about the variety remained very low.Conclusion: The early result shows that demonstration plots were not effective, suggesting that more effective approaches should be explored. It may also be the case that the assessment was too early in the adoption cycle, in which case results after two more seasons of promotion will provide a better estimate of the effect.

Abstract Purpose Push–pull is an intercropping technology that is rapidly spreading among smallholder farmers in Sub-Saharan Africa. The technology intercrops cereals with Desmodium to fight off stem borers, eliminate parasitic weeds, and improve soil fertility and yields of cereals. The above-ground components of push–pull cropping have been well investigated. However, the impact of the technology on the soil microbiome and the subsequent role of the microbiome on diverse ecosystem benefits are unknown. Here we describe the soil microbiome associated with maize—Desmodium intercropping in push–pull farming in comparison to long-term maize monoculture. Methods Soil samples were collected from long-term maize—Desmodium intercropping and maize monoculture plots at the international centre for insect physiology and ecology (ICIPE), Mbita, Kenya. Total DNA was extracted before16S rDNA and ITS sequencing and subsequent analysis on QIIME2 and R. Results Maize—Desmodium intercropping caused a strong divergence in the fungal microbiome, which was more diverse and species rich than monoculture plots. Fungal groups enriched in intercropping plots are linked to important ecosystem services, belonging to functional groups such as mycorrhiza, endophytes, saprophytes, decomposers and bioprotective fungi. Fewer fungal genera were enriched in monoculture plots, some of which were associated with plant pathogenesis and opportunistic infection in humans. In contrast, the impact of intercropping on soil bacterial communities was weak with few differences between intercropping and monoculture. Conclusion Maize—Desmodium intercropping diversifies fungal microbiomes and favors taxa associated with important ecosystem services including plant health, productivity and food safety.

The article considers the impact of the colonial past of some countries in sub-Saharan Africa and its effect on their development during the post-colonial period. The negative consequences of the geopolitical legacy of colonialism are shown on the example of three countries: Nigeria, the Democratic Republic of the Congo and the Republic of Angola, expressed in the emergence of conflicts in these countries based on ethno-cultural, religious and socio-economic contradictions. At the same time, the focus is made on the economic factor and the consequences of the consumer policy of the former metropolises pursuing their mercantile interests were mixed.
