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 impacts of climate change (CC) are expected to be higher in developing countries (e.g. Sub-Saharan Africa). However, these impacts will depend on agriculture development and resilience. Therefore, this paper provides a comprehensive analysis of the multifaceted relationships between CC and agriculture in Burkina Faso (BF). A search performed in March 2020 on the Web of Science yielded 1,820 documents and 217 of them were included in the systematic review. The paper provides an overview on both bibliometrics (e.g. journals, authors, institutions) and topics addressed in the literature viz. agriculture subsectors, climate trends in BF, agriculture and CC mitigation (e.g. agriculture-related emissions, soil carbon sequestration), impacts of CC on agriculture (e.g. natural resources, crop suitability, yields, food security) as well as adaptation strategies. BF is experiencing CC as evidenced by warming and an increase in the occurrence of climate extremes. The literature focuses on crops, while animal husbandry and, especially, fisheries are often overlooked. Moreover, most of the documents deal with CC adaptation by the Burkinabe farmers, pastoralists and rural populations. Analysed adaptation options include conservation agriculture and climate-smart agriculture, irrigation, crop diversification, intensification, livelihoods diversification and migration. However, the focus is mainly on agricultural and individual responses, while livelihoods strategies such as diversification and migration are less frequently addressed. Further research is needed on the dual relation between agriculture and CC to contribute to the achievement of the Sustainable Development Goals. Research results are crucial to inform policies aimed at CC mitigation and/or adaptation in rural BF.

Abstract This chapter examines the role of formal education, training and skills development in Conservation Agriculture (CA) in Sub-Saharan Africa (SSA) in the context of the region's agricultural transformation systems. It explores nascent literature on potential reforms that include development of CA educational programmes and linkages that are more strategically attuned to national agriculture development aspirations. The chapter highlights theoretical grounds and practical examples for the multi-level strategies with complementary relationships aimed at facilitating systemic CA-related education, training and skills development to accelerate and expand its uptake in Africa. The chapter has advocated educational institutions and the university in particular to orchestrate the CA innovation value chain through 'internal' alignment of actors at institutional level (i.e. intra-organizational mainstreaming). The success of an innovation also depends on its 'external' viability. This was illustrated by proposing inter-organizational mainstreaming and a triple helix model where government and industry, respectively, are the principal actors towards increase in sociotechnical viability of the CA innovation system. There are obvious hurdles related to the interactions and coordination between stakeholders, as well as the integration of value complementarities across the value chain. Probable corrective strategies have been exhaustively interrogated and they are, for instance, manifested through technical and organizational adaptations as they summarize and compare systematically their contributions, arguments, assumptions and limitations in the process of creating and harnessing economies of scope in innovation. There may not be any ideal model for demand-led, CA-related education, training and skills development. A number of strategic options present themselves and, in a dynamic world, all strategies are relatively short-lived but must yield outcomes that contribute to longer-term goals. The educational institutions should find appropriate themes and avenues worthy of support in their own right, and projects that invite collaboration on their own terms.

There has been low uptake of soil fertility improving tree technologies that have been promoted as alternatives to the costly inorganic fertiliser among the poor resource farmers of Sub Saharan Africa. This is surprising given that the majority of smallholder farmers cannot afford inorganic fertilisers. Are these technologies effective? Using data collected in 2013 from 1,231 households across six districts of Zambia, this study showed that the tree technologies increased maize productivity. However, increases in maize productivity were less than those obtained from controlled on-station and field experiments where the technologies could double or more than double maize productivity according to literature. The technologies capacity to marginally contribute to wealth creation was confirmed. Socioeconomic constraints including labour, information access, land and credit need to be tackled for the technologies to give maximum benefits. Research on fertiliser trees should therefore be redirected towards the discovery of such resource constraints saving technologies.
