Cassava is cultivated widely in the tropic and sub-tropic parts of Africa, Asia, and Latin America at altitudes from 0 to 2,000 m above sea level. The roots are the principal economic product, whereas the leaves are widely processed for human consumption and animal feed.


Cassava roots are processed into a diverse range of food and animal products, and industrial raw materials. The most important primary product is starch, which is used in many industrial applications such as food, textile, paper, pharmaceutical and other industries. In Africa, cassava is produced almost exclusively for food.

Current challenges related to cassava production include pest and diseases as well as storability of the roots, food safety (potential cyanide release) and suitability of newly bred varieties for food and industrial uses. Future increases in cassava consumption in Africa will depend on advancements in its processing into diverse food forms, or in using it as an alternative to imported wheat, rice and corn starch targeting the urban consumers.

Adu Gyamfi Poku, Regina Birner, Saurabh Gupta. 2018. making Contract Farming Arrangements Work In Africas Bioeconomy: Evidence From Cassava Outgrower Schemes In Ghana. Sustainability (10): 1-21 Pp.

This paper uniquely focuses on rapidly-developing domestic value chains in Africa’s
emerging bioeconomy. It uses a comparative case study approach of a public and private cassava
outgrower scheme in Ghana to investigate which contract farming arrangements are sustainable for
both farmers and agribusiness firms. A complementary combination of qualitative and quantitative
methods is employed to assess the sustainability of these institutional arrangements. The results
indicate that ad hoc or opportunistic investments that only address smallholders’ marketing
challenges are not sufficient to ensure mutually beneficial and sustainable schemes. The results
suggest that firms’ capacity and commitment to design contracts with embedded support services for
outgrowers is essential to smallholder participation and the long-term viability of these arrangements.
Public-private partnerships in outgrower schemes can present a viable option that harnesses the
strengths of both sectors and overcomes their institutional weaknesses.

Adeyemo, T.a., Abass, A., Amaza, P., Okoruwa, V., Akinyosoye, V. & Salman, K.k.. 2015. increasing Smallholders’ Intensity In Cassava Value Web: Effect On Household Food Security In Southwest Nigeria. Conference On International Research On Food Security, Natural Resource Management And Rural Development (na): Na Pp.

Although cassava production and processing is on the increase in Nigeria, there is still a large gap to be filled in meeting the food and raw material need of the country in terms of cassava products and by-products. The reported increase in area cultivated with cassava has not been translated to higher resource use efficiency or productivity, thus cassava smallholders have low physical and economic returns on their activities. This has serious implications for their well-being attributes, chiefly food security. A value web system, involving multiple enterprises within interconnected value chains, has been proposed as a strategy for smallholders to increase resource use efficiency and financial benefits. This study examined the levels of intensity by which cassava smallholders utilise the cassava biomass using available resources. It also isolated the determinants of the different levels of participation in the cassava biomass value web. The study further investigated the effect of higher intensity of cassava biomass utilisation by smallholders on the food security status of their households with respect to their calorie intake and dietary diversity. The study also profiled the different risks to food security based on the level of intensity of the smallholders’ participation in the cassava value web. The research used data from a survey of 150 cassava smallholders, from 7 local government areas in Ogun state Nigeria. The results revealed that food security status of households using the cost of calorie index generally increased with increasing intensity of participation in the cassava value web. Dietary diversity of households also increased with an increase in the intensity of participation in the cassava web. Smallholders who are multitasking are also less vulnerable to food insecurity. The study also found that smallholders are rational and respond to changes in market conditions for their products and are willing to take more active roles in the cassava value web. Policy thrust should thus focus on increasing market opportunities for smallholders which will serve as incentives to take more active roles in the cassava value web, with consequence for their productivity, income and hence food security.
