“…The result implies that households prefer to diversify their crop production when they do not have access to fertilizer and seed. This is partially because good access to input may lead to specialization in a specific crop and this is in line with the results of Bowman and Zilberman () and Ayanwale et al () who found that agricultural modernization and good access to input can lead to specialization in a specific crop. According to Dorjee et al .…”

Formulating policy to strengthen rural livelihood in a country like Benin may be very challenging. This paper investigates the effect of input policies on crop diversification in rural Benin. Multistage sampling techniques have been used to collect primary data from 522 households in the Collines Region. Considering access to fertilizer and seed policies, we used a linear regression analysis to find that access to fertilizer and seed negatively affect the extent of crop diversification. Although some factors (household size and access to extension services) have a positive relationship with crop diversification, we maintain that if the government wants to promote crop diversification as a farmer's strategy to manage risk and uncertainty, there is a need to rethink the input policies. Nevertheless, making fertilizer and seed accessible to farmers is a great opportunity in a country where access to inputs is the major agricultural constraint.

“…The results are consistent with Aighewi et al (2002) and Mignouna et al (2015) that indicated that quality seed yam unavailability constitutes the major limitation of yam production. Moreover, the BCRs of all the research options imply that investment in research and dissemination of these technologies is worthwhile and economically viable as the benefits greatly outweigh the costs as in agreement with many similar studies on ex ante impact assessment ( Akinola et al, 2009 ; Ayanwale et al, 2013 ; Kostandini et al, 2009 , 2011 ). The NPVs oscillate between US$581 million and US$1392 million with the highest for NRC.…”

Potential returns to yam research investment in sub-Saharan Africa and beyond

Lack of good-quality planting materials has been identified as the most severe problem militating against increased agricultural productivity in sub-Saharan Africa (SSA) and beyond. However, investment of research efforts and resources in addressing this menace will only be feasible and worthwhile if attendant economic gains are considerable. As a way of investigating the economic viability of yam investment, this research has been initiated to address problems confronting yam productivity in eight countries of SSA and beyond: Nigeria, Ghana, Benin, Togo, Côte d’Ivoire, Papua New Guinea, Jamaica, and Columbia. Research options developed were to be deployed and disseminated. Key technologies include the adaptive yam minisett technique (AYMT), varieties adapted to low soil fertility and drought, nematode-resistant cultivars (NRC), and crop management and postharvest practices (CMPP). This article aims at estimating the potential economic returns, the expected number of beneficiaries, and poverty reduction consequent to the adoption of technology options. Estimates show that the new land area that will be covered by the technologies in the eight countries will range between 770,000 ha and 1,000,000 ha with the highest quota accounted for by AYMT. The net present value will range between US$584 and US$1392 million and was highest for the NRC. The CMPP had the lowest benefit-cost ratio of 7.74. About 1,049,000 people would be moved out of poverty by these technologies by 2037 in the region. These technologies are less responsive to changes in cost than that in adoption rate. Therefore, the realization of the potential economic gains depends on the rate and extent of adoption of these technologies. Giving the knowledge-intensive nature of some of these interventions, capacity building of potential adopters will be critical to increasing the sustainability of the yam sector, thereby enhancing food security and reducing poverty.

“…Agricultural development can come from different sources; while in the past, the increased use of inputs and the expansion of agricultural land accounted for a large part of agricultural growth in Africa. However, innovation attempts to increase output per unit of input is a major driver of growth (Ayanwale et al ., ). In sub‐Saharan Africa, 63 per cent of the population live in rural areas and are employed in agriculture‐related work (Gildemacher et al ., ).…”

“…About 90 per cent of Nigeria's food is produced by small‐scale farmers who cultivate small plots of land and depend on rainfall rather than irrigation systems (IFAD, ). However, the role of agricultural innovation in poverty reduction, improving livelihood and enhancing productivity outcomes cannot be over emphasized (Ayanwale et al ., ).…”

Agricultural research programmes driven by agricultural innovation system concepts usually aim to change the way in which low income rural agrarian households in a nation like Nigeria communicate with the market and the decisionmaking strategies pertaining to development of their agri-business and the scarce resources which are at their disposal. We assess the extent to which the use of these innovative agricultural research interventions impact upon the livelihood and productivity outcomes of rural smallholder farmers in sub-Saharan African using a case study of Nigeria. Using propensity score matching as a means of establishing a valid counterfactual and single differencing to measure impact, the study establishes that rural incomes and output are significantly impacted by agricultural research interventions that are driven by agricultural innovation systems concepts. The study finds that participating households had better livelihood, productivity and more diversified income portfolios during the implementation of innovative research intervention as a result of greater linkages to markets and capacity building opportunities; phasing out of the research programme reduced the diversity of income portfolios and led to the erosion of livelihoods. Therefore, agricultural innovation system concepts should be mainstreamed in all public agricultural extension and research programmes.
