Promoting Cassava as an Industrial Crop in Ghana: Effects on Soil Fertility and Farming System Sustainability

Cassava is an important starchy staple crop in Ghana with per capita consumption of 152.9 kg/year. Besides being a staple food crop, cassava can be used as raw material for the production of industrial starch and ethanol. The potential of cassava as an industrial commercial crop has not been exploited to a large extent because of perceptions that cassava depletes soils. Recent finding from field studies in the forest/savannah transitional agroecological zone of Ghana indicates that when integrated in the cropping system as a form of rotation, cassava contributes significantly to maintenance of soil fertility, and thus large scale production of cassava for industrial use can contribute to poverty reduction in an environmentally responsive way. This paper discusses the role of cassava cultivation in soil fertility management and its implication for farming system sustainability and industrialization

Embedding research for innovation to meet societal needs in national research systems : Experiences from Ghana

The experiences synthesised in this article indicate how significant effects in two agricultural domains have been achieved by creating pathways for inter-dependent socio-technical and institutional changes, at a range of levels of action, governance and policy-making. The synthesis emphasizes the importance of co-learning, experimentation, and critical reflection among a wide network of 'champions' of transformational change on behalf of smallholder farmers and processors. It shows that innovation processes may involve actors along entire value chains, industry leaders at national level, or local level actors seeking to widen the space for change beyond their immediate circle of direct influence. While the research and development initiatives of the domains are shown to have been critical in identifying the constraints and opportunities of smallholders, and also to the effects documented, this was largely because the research effort converged around empirically grounded problems and opportunities identified. The information sought, and the solutions found useful, were determined by the members of innovation platforms that drove the processes of change.</p

Innovation platforms and projects to support smallholder development - experiences from Sub-Saharan Africa

Innovation as a policy goal, normative practice, and a conceptual framing of purposeful human activity, has received increasing attention. The question of what kinds of purposeful innovation might benefit smallholders in developing countries has been raised. This issue presents and analyses the work of Innovation Platforms (IPs) established by the COS-SIS (Convergence of Sciences–Strengthening Innovation Systems) programme in nine agro-enterprise domains in West Africa, drawing on Theory Guided Process Inquiry data recorded through 2011-end 2013. Six papers synthesise individual IP experiences, complemented by a cross-case analysis of external influences on the IPs and their responses, a reflection on how well the IPs in Mali dealt with local conflicts, and an analysis of how the work of the IPs in Ghana led to changes in university curricula and in the researching practices of three leading agricultural institutes. An analysis of thirteen case studies from Kenya, Benin, and South Africa supported by the JOLISAA (Joint learning in and about Innovation Systems in African Agriculture) programme, adds further insights. Five general lessons are drawn, expressed as propositions that can be further tested against others’ experiences: (i) IPs can bring about significant socio-technical and institutional changes at a range of levels, and in a wide variety of agro-enterprise domains and contexts; (ii) the IPs are not isolated from nor independent of the networks of influence in which they are embedded; thus they cannot be treated as the sole causal agents of the changes accomplished; (iii) research that tracks the IPs’ work and performance provides evidence that enables the members to learn from experience and adjust activities in the light of effects; (iv) there is no blueprint for what an IP is nor a recipe for the processes by which such changes are brought about; the form, activities, and changes co-evolve with whatever is happening in the wider context; (v) field-based diagnosis of opportunity, evidence-based information-sharing and experimental exploration of pathways of change establish the legitimacy and influence of IPs

External influences on agro-enterprise innovation platforms in Benin, Ghana and Mali – Options for effective responses

This paper discusses external influences on innovation platforms (IPs) and the options for effective responses. The platforms examined in this paper were conceived as vehicles for facilitating institutional change in support of innovation that benefits smallholders, in selected agro-enterprise domains in Benin, Ghana and Mali. They were designed and implemented in a manner that enabled experimentation with processes of change in the selected domains. A Research Associate in each case facilitated the work of the IPs and applied Theory-Guided Process Tracing (TGPT) methodology to document the innovation processes pursued by platform members. The recorded data allow analysis of the external influences on the IPs. This paper first presents a typology as derived from literature of the main external influences on the domains of interest, and then uses the typology to analyse the influences on and responses of the IPs. The main influences were found to emanate from global, sub-regional and national levels. The IPs' responses were diverse but generally included reconstitution of the membership, lobbying, capacity-building among smallholders, and empowerment of smallholders by organizing provision of new knowledge, skills or financial resources. The paper highlights lessons drawn by the platform members in addressing the challenges involved. It concludes that external influences are important in determining the direction of socio-technical and institutional innovation

Triggering regime change: A comparative analysis of the performance of innovation platforms that attempted to change the institutional context for nine agricultural domains in West Africa

The article synthesises the experiences of innovation platforms (IPs) that engaged in open-ended experimental action to improve the institutional context for smallholder farm development in West Africa. The IPs sought change at the level of the institutional regime covering an entire agricultural domain (such as cocoa, cotton, oil palm or water management). Their purpose was therefore not to ‘roll out’ farm-level technologies across rural communities. The IPs's outcomes were documented and analysed throughout by means of theory-based process tracing in each of seven of the nine domains in which regime change was attempted. The evidence shows that by means of exploratory scoping and diagnosis, socio-technical and institutional experimentation, and guided facilitation IPs can remove, by-pass, or modify domain-specific institutional constraints and/or create new institutional conditions that allow smallholders to capture opportunity. The article describes the 5-year, €4.5 million research programme in Benin, Ghana and Mali, covering theory, design, methods and results. It is the sequel to Hounkonnou et al. in AGSY 108 (2012): 74–83

An innovation platform for institutional change in Ghana's cocoa sector

Cocoa is a major source of employment, smallholder farmers' incomes, and export revenue in Ghana. However, by 2010 institutional constraints throughout the value chain were failing to sustain bean quality and cocoa production. A national-level innovation platform, comprising key public and private actors in the cocoa sector, was established in 2010 to analyse and act to address this concern. The members' initial inquiries revealed that: farmers indirectly were paying for the national mass spraying and Hi-Tech input programmes, both provided free at the point of delivery. As the largest components in the cost structure, these programmes to a large extent accounted for the low price paid to farmers for their beans; a volatile exchange rate regime meant that often the prevailing rate was not equal to its equilibrium level; policies that heavily taxed cocoa were destroying farmers' expectation of long-term profitability. This paper draws on data recorded from the beginning 2009 to end 2013 by means of theory-guided process tracing 5(TGPT), to show how the platform contributed to increased prices for farmers, to subsequent reform of the input supply arrangements, and to changes to the mass spraying programme. The key causal mechanisms identified are policy learning and progressive amendment of existing institutions. The paper concludes by drawing lessons for the role of an innovation platform.</p
