Engaging rural youth in agribusiness has become an important strategy to create employment opportunities in Africa. To this end, governments and development partners have implemented various interventions that facilitate youth engagement in agribusiness for several years. However, there is a dearth of evidence on what worked and what did not work well, making it difficult to inform evidence-based policy making. In an effort to fill this knowledge gap, a comprehensive literature review of the outcomes of interventions related to youth engagement in agribusiness was conducted using a deductive coding approach. Results showed that the interventions implemented by governments and development partners across Africa have succeeded in producing favorable outcomes despite some limitations. Interventions that integrate capacity development, financial support for startups, and continuous mentorship on the technical and financial aspects of youth-run agribusiness projects proved successful in enhancing youth engagement in agribusiness. This suggests that the design and implementation of future interventions should be based on an integrated approach that considers diversity of youths’ aspirations and shared capabilities, interests, expectations, as well as challenges associated with access to resources and participation in collective action. The design of future interventions should also be built on strong partnerships among rural communities, academia, research, and private sector for increased impact on livelihood improvements.

• We examine the impact of improved cowpea adoption on poverty in Nigeria. • We use a unique and recent nationally representative survey data. • Adoption leads to an increase in household income and asset ownership. • Poverty reduces with the adoption of improved cowpea varieties.

Knowledge on the spread and distribution of insecticide resistance in major malaria vectors such as Anopheles funestus is key to implement successful resistance management strategies across Africa. Here, by assessing the susceptibility status of an inland population of An. funestus Giles (Kpome) and investigating molecular basis of resistance, we show that multiple resistance and consistent plasmodium infection rate are present in Anopheles funestus populations from Kpome. The insecticide susceptibility level of collected Anopheles funestus was assessed. Synergist (PBO) was used to screen resistance mechanisms. The TaqMan technique was used for genotyping of insecticide resistant alleles and detecting plasmodium infection levels. The nested PCR was used to further assess the plasmodium infection rate. The TaqMan analysis of plasmodial infections revealed an infection rate (18.2 %) of An. funestus in this locality. The WHO bioassays revealed a multiple phenotypic resistance profile for An. funestus in Kpome. This population is highly resistant to pyrethroids (permethrin and deltamethrin), organochlorines (DDT), and carbamates (bendiocarb). A reduced susceptibility was observed with dieldrin. Mortalities did not vary after pre-exposure to PBO for DDT indicating that cytochrome P450s play little role in DDT resistance in Kpome. In contrast, we noticed, a significant increase in mortalities when PBO was combined to permethrin suggesting the direct involvement of P450s in pyrethroid resistance. A high frequency of the L119F-GSTe2 DDT resistance marker was observed in the wild DDT resistant population (9 %RS and 91 %RR) whereas the A296S mutation was detected at a low frequency (1 %RS and 99 %SS). The presence of multiple resistance in An. funestus populations in the inland locality of Kpome is established in this study as recently documented in the costal locality of Pahou. Data from both localities suggest that resistance could be widespread in Benin and this highlights the need for further studies to assess the geographical distribution of insecticide resistance across Benin and neighboring countries as well as a more comprehensive analysis of the resistance mechanisms involved.

The International Institute of Tropical Agriculture (IITA) has applied the concept of ‘circular bioeconomy’ to design solutions to address the degradation of natural resources, nutrient-depleted farming systems, hunger, and poverty in sub-Saharan Africa (SSA). Over the past decade, IITA has implemented ten circular bioeconomy focused research for development (R4D) interventions in several countries in the region. This article aims to assess the contributions of IITA’s circular bioeconomy focused innovations towards economic, social, and environmental outcomes using the outcome tracking approach, and identify areas for strengthening existing circular bioeconomy R4D interventions using the gap analysis method. Data used for the study came from secondary sources available in the public domain. Results indicate that IITA’s circular bioeconomy interventions led to ten technological innovations (bio-products) that translated into five economic, social, and environmental outcomes, including crop productivity, food security, resource use efficiency, job creation, and reduction in greenhouse gas emissions. Our gap analysis identified eight gaps leading to a portfolio of five actions needed to enhance the role of circular bioeconomy in SSA. The results showcase the utility of integrating a circular bioeconomy approach in R4D work, especially how using such an approach can lead to significant economic, social, and environmental outcomes. The evidence presented can help inform the development of a framework to guide circular bioeconomy R4D at IITA and other research institutes working in SSA. Generating a body of evidence on what works, including the institutional factors that create enabling environments for circular bioeconomy approaches to thrive, is necessary for governments and donors to support circular bioeconomy research that will help solve some of the most pressing challenges in SSA as populations grow and generate more waste, thus exacerbating a changing climate using the linear economy model.

The proponents of the entrepreneurial motivation dichotomy have argued that opportunity-driven entrepreneurs are more likely to succeed and sustain in entrepreneurship, unlike people who start-up businesses out of necessity. However, disagreement still exists on why and under which conditions the former might outperform the latter. This research contributes to this debate by examining the mediation role of psychological capital in the relationship between entrepreneurial motivation and business success among youths. This study relied on a random sample of 295 young entrepreneurs surveyed from Bukavu in the Democratic Republic of the Congo (DRC). We applied partial least squares to analyze the hypothesized relationships. Evidence for the positive effect of opportunity-led motivation on psychological capital was found, but the findings did not support any direct effect of entrepreneurial motivation on business success. Instead, psychological capital positively and significantly mediated the relationship between entrepreneurial motivation and business success. This paper makes a distinctive new contribution to the understanding of the intriguing and controversial entrepreneurial motivation dichotomy—a business success relationship. To this end, we have found out that opportunity entrepreneurs have 3% more chance of succeeding in businesses compared to necessity entrepreneurs, because the former outperform the latter by 4% in the dimensions of psychological capital. This paper has new policy implications, as it reveals the great importance of psychological capital in promoting business success, thus reducing unemployment among youths, and offers tips from which psychological capital can be built or improved.

Involvement of youth in horticulture agribusiness has become a vital approach to create employment opportunities among the youth in Tanzania. This study aimed at examining the extent of youth participation and factors influencing youth involvement in horticulture agribusiness with a focus on innovations in post-harvest management (PHM). Data were collected from a sample of 576 male and female youth in Njombe region using a multi-stage random sampling technique. Data were analyzed using an ordered logit model and descriptive statistics. Results of the ordered logit analysis showed that primary school education, Form IV and above, management innovation, access to credit, good perception of horticulture for agribusiness and improved packaging materials positively and significantly influence youth involvement in horticulture agribusiness. Gender and land size had a negative and significant influence on youth involvement in horticulture agribusiness, as indicated by higher percentages of male youth (59%) participation in the horticulture agribusiness. Therefore, this study suggests increased investment in capacity development of the youth on PHM innovations and the development of rural infrastructure such as agro-processing and storage facilities by the government and private sector. Increasing the availability of improved packaging materials and provision of youth-friendly credit schemes could encourage youth in horticulture agribusiness.
