Seed systems for roots, tuber, and banana (RTB) crops receive relatively little attention from development-oriented research commercial seed sector actors, despite their importance food security, nutrition rural livelihoods. We review RTB systems—with particular reference to potato, sweetpotato, cassava, yam —to reflect on current system development approaches the unique nature of these systems. refer our own experiences, literature 13 case studies interventions identify gaps in knowledge...
Seed systems research is central to achieving the United Nations Sustainable Development Goals. Improved varieties with promise for ending hunger, improving nutrition, and increasing livelihood security may be released, but how do they reach benefit different types of farmers? Without widespread adoption genetic gains achieved improved crop can never actualized. Progress has been made toward demand responsive breeding, however draft CGIAR 2030 Research Innovation Strategy fails recognize...
Vegetatively propagated crop (VPC) seed tends to remain true varietal type but is bulky, often carries disease, and slow produce. So VPC needs be handled differently than that of other crops, e.g., it sourced locally, must fresh, less sold on the market. Hence, a framework was adapted describe support interventions in such systems. The used with 13 case studies understand systems for roots, tubers, bananas, including differing roles sometimes conflicting goals stakeholders, identify...
Disaster plant pathology addresses how natural and human-driven disasters impact diseases the requirements for smart management solutions. Local to global drivers of disease change in response disasters, often creating environments more conducive disease. Most have indirect effects on health through factors such as disrupted supply chains damaged infrastructure. There is also potential direct from pathogen or vector dispersal due floods, hurricanes, human migration driven by war. Pulse...
Over recent decades international agricultural research has shown that it can generate technologies with benefits for societies in the Global South outstrip investments many times over. However, also been generated are not evenly spread and do reach some groups of farmers at all. Too often, segments intended target populations left out these often tend to be those already ‘left behind’. New seeds varieties important elements development relies on seed delivery systems get new farming...
Abstract Virus infection in seed potato reduces yield, and the problem is exacerbated when an early-generation affected. The prevalence of six key viruses, PVY, PVX, PLRV, PVA, PVS, PVM, was assessed among decentralized multipliers such as individuals, farmer group cooperatives, private companies, agricultural research centers that produce early generation major growing districts Ethiopia. A total 262 leaf samples were randomly collected from plants analyzed using a double antibody sandwich...
Smallholder potato farmers in Ethiopia do not realize the theoretical yield potential of crop because they benefit from advantages using quality seed improved varieties. The high disease incidence potatoes has large implications on farming system since country lacks appropriate assurance mechanisms. Seed relies more technical support provided by national research and extension systems than official certification agency. This paper elaborates systematic challenges opportunities within poses...
This study examined the nutrition and food security impacts of a project that was designed to improve availability disease-free planting materials biofortified orange-fleshed sweetpotato (OFSP) in rural Tanzania. Difference-in-difference matching techniques were employed estimate causal effects using panel data. Participation increased agronomic nutritional knowledge households, raised uptake rate for OFSP varieties, improved status. Effects on are, however, weak. These results suggest...
The Nutrition Section of the Mozambican Ministry Health recently implemented a low-cost, rapid field tool for assessing quality household diets. Such tools can play an important part in targeting development assistance countries where resources are scarce. This paper evaluates how well performs at describing dietary intakes northern Mozambique and explores ways to improve it. food-group classification scoring system that form core were applied data (n = 1,140) collected previous quantitative...
Abstract Smallholders in Eastern and Southern Africa(ESA) have limited access to timely availability of quality sweetpotato seed which contributes sub-optimal root yields. To enhance it is necessary link formal plant breeding efforts a sustainable supply system by means identifying business opportunities for Early Generation Seed (EGS) producers. In most ESA countries, public institutions the sole mandate EGS production, but not adopted an explicit orientation. The study used primary...
We examined the effect of multidimensional farmers' beliefs on likelihood cultivating planting materials biofortified orange-fleshed sweetpotato (OFSP) varieties. Using a panel dataset and combining difference-in-differences regression with propensity score matching, results showed positive effects related to health benefits, yielding ability, sweetness, disease-resistance, storability, early maturity, colour, that children enjoy eating OFSP roots, cultivation The proportion roots out total...
Efforts to combat vitamin A deficiency in children and pregnant mothers have focused on promotion of nutritionally enhanced food security crops. Such efforts recently targeted the production consumption these The orange-fleshed sweetpotato (OFSP) is one most known However, access quality planting materials OFSP vegetatively propagated crops by farmers remains a major constraint. This study used discrete count data regression models collected from 732 farm households Tanzania test effect...
Viruses pose a major challenge to sweetpotato production in Tanzania. Use of cleaned-up, virus-tested seed vines distributed through formal system is among the proposed strategies address this challenge. However, can get infected once field and it not known how they will perform following several seasons on farm propagation. We assessed performance farmer-sourced susceptible variety, Ejumula, relatively tolerant Kabode, over five understand trend root yields, vine yields virus incidences....
Virus-related degeneration constrains production of quality sweet potato seed, especially under open field conditions. Once in the open, virus-indexed seed is prone to virus infection leading decline performance. Insect-proof net tunnels have been proven reduce researcher management. However, their effectiveness farmer-multiplier management not known. This study investigated ability Infection and were assessed for two cultivars, Kabode Polista, grown fields at sites with varying pressures....
Abstract Finding out how to scale innovations successfully is high on the agendas of researchers, practitioners and policy makers involved in agricultural development. New approaches methodologies seek better address related complexities, but none them include a systematic perspective role capacity (partnerships for) scaling innovations. We posit that this has left an important topic insufficiently addressed relation partnerships for The need gap became apparent context CGIAR Roots, Tubers,...
Abstract The principal selection objective in crop breeding has for a long time been driven by agronomic gains like yield maximization and climate resilience. Nevertheless, the continued low adoption of new varieties documented gender technology gap triggered re‐thinking this strategy, with end‐user acceptability released key strategy objectives. Using mixed‐methods approach survey 122 producers focus group discussions 200 male female two major sweetpotato [ Ipomoea batatas (L.) Lam]...
Abstract Sweetpotato is an important food crop in global production. However, sweetoptato viruses pose a threat to sustainable agriculture and cause significant economic loss. More than 30 have been reported date, with sweet potato feathery mottle virus (SPFMV) chlorotic stunt (SPCSV) occurring frequently combination, causing sweetpotato disease. The detection of directly from still challenge, efforts are being made toward this front. Therefore, rapid critical for effective control. Current...
