The role of institutions and networks in developing the bioeconomy : case studies from Ghana and Brazil
(2019) Scheiterle, Lilli; Birner, Regina
An increasing number of countries have begun putting focus on developing a bioeconomy strategy. The bioeconomy provides a new concept with the aim to design a sustainable economy, which is knowledge-based and based on the use of biological resources. This entails on the one hand higher production of biomass and on the other tighter networks of traditional, national and international institutions. Institutional networks are pivotal for the sustainable production and use of biological resources, as well for the development of innovative biological processes and principles to exploit the potential of biomass. This thesis explores three pivotal aspects needed to take advantage of the considerable untapped potential of the bioeconomy. The first case study aims to identify the determinants of the persisting low maize yields in northern Ghana, despite the introduction of a fertilizer subsidy program. The policy is largely regarded as an instrument to increase crop productivity and contribute to food security. The second empirical study explores the role of female-led market institutions in Ghana. Marketing is central to the development of the bioeconomy and as such, trader organizations have a key role to play the value chain. The third case study investigates, taking sugarcane as a case study example, how well Brazil, the world’s leader in sugarcane production, is positioned to realize the shift from a fossil-based to a bio-based economy (bioeconomy). The two case study countries Ghana and Brazil were chosen because of their comparable net primary productivity and pedo-climatic conditions, and because of their different stages in the realization of the bioeconomy. Two components are pivotal to the success of the bioeconomy: biomass and knowledge. Based on two case studies in Ghana, this thesis investigates first the efforts to increase maize productivity in the Guinea savanna and secondly explores the role of collective action groups as central actors to address the sustainability dimension of the bioeconomy. Brazil has successfully implemented pivotal aspects of the bioeconomy, especially in the sugarcane sector. For this reason it lends itself well to analyze the role of institutions and networks in the development of new processes and products. This study adopts a mixed methods approach to address three key aspects of the development of the bioeconomy: production, marketing, and the overall innovation system. Data collection and analysis included qualitative and quantitative methods from various disciplines. The findings are presented in three papers, which this cumulative thesis is composed of. The first paper adopts a multidisciplinary approach. A household survey, in-depth interviews, and focus group discussions served to gather data on the socio-economic challenges of maize production in the Guinea savanna. Additionally, soil and fertilizer samples were analyzed to identify natural constraints and potential governance challenges. The results from this paper show that both socio-economic and biophysical parameters contribute to an improved understanding of site-specific challenges, resulting in low maize productivity in the Guinea savanna of Ghana. The second paper explores the role of female-led market associations across regions, ethnicities, and market typologies throughout Ghana. For this study a qualitative approach was chosen with participant observation and in-depth open-ended interviews conducted with traders, both in and out of leadership positions. The results could not empirically confirm the prevailing discourse on the monopolizing power of female-led market associations. The study rather finds that traders’ collective action provides vital safety-net measures for asset-poor women engaging in risky market activity. However, the public perception is challenging female trader agencies. The third paper analyzes the role of institutions and focuses on the innovation networks in the sugarcane sector in Brazil. The study combines the novel concept of ‘biomass value-webs’ with the established National Innovation System concept. For data collection, in-depth interviews and Net-Maps as a participatory tool were applied. The results illustrate the importance of innovation networks for Brazil to become a front-runner in the future bioeconomy. In particular, it emphasizes the importance of integrating national and international private sector organizations, and the need for incentives to foster collaboration with knowledge institutions. Based on these findings, one can conclude that strengthening the efforts to tailor site-specific solutions that consider the inter-disciplinary nature of crop production, marketing and development of processes is crucial to the bioeconomy. Overall, more attention to innovation networks is required to master the challenges of the bioeconomy and take full advantage of its opportunities.
