Enhancing cassava productivity through healthy planting material
This technology leverages regulatory oversight, digital innovation, and community empowerment to ensure cassava seed quality. National certification bodies conduct inspections at higher levels, while local producers engage in quality-declared seed production. The system includes phytosanitary practices, roguing, and use of tools like PlantVillage Nuru for pest and disease diagnosis. Seed Tracker supports registration and tracking, and labeling improves transparency.
This technology is pre-validated.
The poor: Positive high
The technology is strongly beneficial for the poor, for whom cassava is a key source of food and income
Women: No impact
The technology is gender neutral
Climate adaptability: Highly adaptable
Cassava is known to be one of the most climate resilient crops
Farmer climate change readiness: Significant improvement
Boosting cassava productivity is an excellent way to adapt to potential climate change impacts and cassava is less likely to be negatively impacted than other crops
Carbon footprint: A bit less carbon released
Greater land productivity can enhance land use efficiency which prevents increases in carbon emissions
Biodiversity: Not verified
Not verified
Environmental health: Not verified

Persistent disease pressure: Cassava viral diseases can reduce the effectiveness of interventions intended to improve cassava productivity when infected planting materials continue to circulate.
Limited supply of quality seed: Weak certification systems can constrain the availability of healthy, improved cassava planting materials for farmers.
Difficulties verifying results: Inadequate traceability and certification records can make it difficult to verify the quality and origin of seeds distributed through supported activities.
Fragmented seed-system coordination: Weak links among regulators, researchers, seed producers, and advisory services can undermine coordinated seed quality management.
Limited participation of rural entrepreneurs: Barriers to certification and formal market entry can exclude smaller seed producers, women, and young people from commercial opportunities.
Challenges sustaining seed quality: Without effective regulatory systems, digital monitoring, and local production capacity, quality assurance may remain inconsistent across seed supply chains.
Support certification system development: Development partners can provide technical assistance to assess existing seed systems and adapt cassava-specific certification guidelines to national conditions.
Strengthen regulatory capacity: Training and institutional support can help seed inspection officers identify diseases, conduct field inspections, and apply certification procedures consistently.
Enable digital monitoring: Support for Seed Tracker or compatible digital systems can improve field registration, inspection documentation, and seed traceability.
Expand community-based seed production: Assistance for QDS approaches can help eligible local producers, including women and young people, participate in quality seed production.
Improve phytosanitary management: Support for disease identification tools such as PlantVillage Nuru and for appropriate field practices can strengthen disease surveillance and management.
Promote sustainable seed-sector development: Investment in certification, labeling, producer capacity, and coordination among seed-system actors can help create more reliable supply channels for quality cassava planting materials.
Of course, Béata. Here’s a version of the text tailored for development institutions, with a focus on impact, scalability, inclusion, and alignment with development goals:
The Cassava Seed Quality Management System is a proven, scalable solution that development institutions can integrate into agricultural programs to boost food security, climate resilience, and rural livelihoods. By ensuring access to certified, disease-free planting material, the system enhances productivity and reduces yield losses, particularly for smallholder farmers. It directly contributes to SDGs 1 and 2, while reinforcing national agricultural strategies.
To incorporate this technology into development programs, institutions should:
Adopting this system can help development programs scale their impact efficiently, while building resilient, inclusive, and market-responsive seed systems across Africa.

Scaling Readiness describes how complete a technology's development is and its ability to be scaled. It produces a score that measures a technology's readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.
Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.
The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

1. Baseline Assessment: Evaluate the current cassava seed system to determine:
2. Design/Modification of Certification Guidelines: Develop or adapt certification guidelines using successful models:
3. Update National Seed Policy: If cassava certification is new, collaborate with stakeholders to validate guidelines and incorporate them into national seed regulations.
4. Train Seed Inspection Officers: Provide training on cassava field certification procedures, including disease recognition (CMD and CBSD), and develop strategies to train community-level or QDS producers in self-certification.
5. Certification Labelling: Design electronic labels for each cassava seed category and distribute them to seed producers post successful certification inspections.
6. Digital Monitoring: Implement or adapt digital systems (e.g., Seed Tracker™) for managing cassava seed field registration and certification.
7. Roll Out: Launch the certification system, starting with higher seed classes. Gather user feedback and invest in the system through strategic support, similar to other major staples like maize.
