A technical review of modern cassava technology adoption in Nigeria (1985-2013): Trends, challenges, and opportunities
(Report, 2016-04-13) Oparinde, Adewale; Abdoulaye, Tahirou; Manyong, Victor M.; Birol, Ekin; Asare-Marfo, Dorene; Kulakow, Peter; Ilona, Paul
In recent times, results of various adoption studies have been mixed, raising questions regarding why some improved farm technologies are still not widely adopted several years after their first introduction. Many improved cassava varieties have been introduced to millions of farm households across Africa south of the Sahara. Using an extensive review of cassava-adoption literature focused on Nigeria, this paper discusses the uptake of improved cassava varieties. Generic measurement and methodological issues in the literature are illuminated and alternative approaches suggested. The literature can be improved to better inform policy by considering issues such as attribution constraint due to varietal identification challenges and sample selection bias that can limit interpretation of findings. Very few studies disaggregated adoption by men and women, thus the literature can provide more policy relevance by giving adequate attention to gender considerations. Also, the use of only descriptive statistics and dichotomous choice models is most common while issues of sequencing, simultaneity, endogenity, and social learning effects in adoption decisions are under-evaluated. The local germplasm at research institutions in the country is not exhaustive and thus efforts should focus on improving the database for an effective use of a DNA fingerprinting technique in the varietal identification process.
Securing Sweetpotato Planting Material for Farmers in Dryland Africa: Gender-Responsive Communication Approaches to Scale Triple S
(Book Chapter, 2022) McEwan, M.; Mourik, Tom A. van; Hundayehu, M.C.; Asfaw, F.; Namanda, S.; Suleman, I.; Mayanja, S.; Imoro, S.; Etwire, P.M.
Triple S (Storage in Sand and Sprouting) is a root-based system for conserving and multiplying sweetpotato planting material at the household level. In sub-Saharan Africa, farmers predominantly source planting material by cutting vines from volunteer plants that sprout from roots left in the field from a previous crop. However, it takes 6 to 8 weeks after the rains start to produce enough vines for planting material, and normally these vines are infected by sweetpotato diseases and pests carried over from previous crops. Where rainfall is unpredictable, farmers can use Triple S to take advantage of the whole growing season, planting and harvesting early to obtain food, higher yields, and income. Triple S facilitates household retention and adoption of new sweetpotato varieties, notably the beta-carotene-rich, orange-fleshed varieties. Triple S PLUS is the combined innovation package of core Triple S components and complementary components used to scale the innovation. These included good agricultural practices, different storage containers, local multiplication and sales of planting material, and a multimedia communication strategy for training and extension to encourage the uptake of Triple S. Components were at different levels of scaling readiness. This chapter explores evidence from Ethiopia and Ghana (2018–2019) on the extent to which exposure to different communication channels and their combinations influenced the uptake of Triple S PLUS by male and female farmers, the partnering arrangements that supported this, and the resulting changes in food security. We discuss implications for future scaling initiatives.

The Innovation Revolution in Agriculture. A Roadmap to Value Creation
(Book, 2021) Campos, Hugo
This open access book is an important reframing of the role of innovation in agriculture. Dr. Campos and his distinguished coauthors address the need for agriculture to feed a growing global population with a reduced environmental footprint while adapting to and mitigating the effects of changing climate. The authors expand the customary discussion of innovation in terms of supply driven R&D to focus on the returns to investors and most importantly, the value to end-users. This is brought to life by exploring effective business models and many cases from agricultural systems across the globe. The focus on converting the results of innovation in R&D into adoption by farmers and other end-users is its greatest contribution. Many lessons from the book can be applied to private and public sectors across an array of agricultural systems. This book will be of enormous value to agri-business professionals, NGO leaders, agricultural and development researchers and those funding innovation and agriculture across the private and public sectors.

Scaling Readiness encourages critical reflection on how ready innovations are for scaling, and what appropriate actions could accelerate or enhance scaling.
The potato crop. Its agricultural, nutritional and social contribution to humankind
(Book, 2020) Campos, Hugo; Ortíz, O.
This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.
Connecting smallholder root and tuber growers to markets through Farmer Business Schools
(Book, 2019-09) International Potato Center
This book features a collection of stories of 24 women and men who participated in Farmer Business Schools in the Philippines and India, and of project staff of partner organizations who have facilitated the process. Since innovations are inherently linked to change in practices and lives, the stories were collected using the ‘most significant change’ (MSC) approach as a technique for capturing project outcomes. MSC is a qualitative evaluation tool based on community members’ response to a simple question: What do you think was the most significant change in your life brought about by this initiative? This encourages community members to tell the story of how their lives are now different and what part of that difference they value the most.

Effects of basal medium and plant growth regulator regimes on meristem and nodal cultures in white yam (D. rotundata)
(Book, 2017) Ajayi, A.; Balogun, M.; Maroya, N.; Asiedu, Robert
Yam production is constrained by the limited availability and high cost of quality seed due to its slow vegetative propagation ratio. Micropropagation using nodal and meristem explants have been used to produce clean plantlets, with a 1:4 multiplication ratio for nodal explants and 1:1 ratio for meristem explants, the latter taking 6 to 24 months before plantlet regeneration. The effect of six hormone-free basal medium compositions, made of Murashige and Skoog (MS) medium and Gamborg’s B5 medium modified mainly in terms of nitrate to ammonium ratio on micropropagation ratio of four genotypes of white yam were investigated using single nodes from in vitro established plantlets. A second experiment was conducted on the effect of different concentrations of NAA (naphthalene acetic acid), GA3 (Gibberellic acid), BAP (benzyl amino-purine), and UP (Uniconazole-p) at different combinations on micropropagation, using a completely randomized design with 20 replicates. Data were collected on number of nodes per plantlet every four weeks for twelve weeks. ANOVA was done and means were separated at P = 0.05. The average number of nodes per plantlet after 12 weeks was 3.76 in conventional MS medium which was the best for all the genotypes except TDr 95/19177 in which there were no significant differences among the different nitrogen regimes. The B5 medium produced the lowest number of 1.85 nodes after 12 weeks of culture. Nitrogen use efficiency seems to differ among genotypes, necessitating the use of an ion-specific nutrient test for increased optimization. Medium containing 0.2 mg/l BAP and 0.1 g/l UP in MS medium produced the highest mean number of nodes (6.5) after 12 weeks. Both mineral nutrition and hormones were effective in increasing the yam micropropagation ratio.
Tools for understanding the agricultural production systems and their socio-economic context in target regions for the introduction of new banana cultivars: baseline intra-household survey.
(Manual, 2017-01-01) Crichton, R.; Ainembabazi, John H.; Caron, Cynthia M.; Bergh, Inge van den
Within the framework of the IITA-led project “Improvement of banana for smallholder farmers in the Great Lakes region of Africa” (also known as the “Breeding Better Bananas” project, http://breedingbetterbananas.org), Bioversity International and partners conducted baseline research in the target regions of Luwero and Mbarara in Uganda, and Bukoba, Meru, Moshi and Rungwe in Tanzania during 2015-2016, prior to conducting on-station and on-farm evaluations of the new NARITA banana cultivars. Five tools were used to characterise the banana and agricultural production systems, and the socioeconomic context of these systems, in the target regions. The research used a mixed-methods, participatory and sex-disaggregated approach to ensure that the knowledge, experiences and opinions of as many people as possible were obtained. The understanding gained from the baseline research will: • Be fed into the banana breeding pipeline at multiple entry points to assist with breeding banana cultivars that better meet the requirements of the users. Some of these entry points are: setting of breeding targets; selection of parent material; evaluation in regional on-station and on-farm trials; participatory varietal selection taking into account the criteria (or ‘trait preferences’) that are important to multiple and different users; facilitating access to and adoption of the new cultivars by farmers and other end-users through scaling up the supply of clean planting materials and ensuring equitable distribution of these through the ‘seed’ systems. • Inform the ongoing adaptive management of the project activities to ensure fair participation and decision-making by people in the affected communities. • Provide the baseline to evaluate, in conjunction with the endline, the impact of adoption of the new cultivars on households, and individuals within, in the target regions.
