Enhancing cassava productivity through healthy planting material
The system operates under national seed regulations, combining inspection protocols, phytosanitary measures, and digital platforms. It enables quality assurance from breeder-level seed to farmer-level distribution. National regulators define standards and oversee compliance through certification inspections, while also promoting community-based quality-declared seed (QDS) systems. Tools like Seed Tracker and PlantVillage Nuru support efficient field registration, inspection recording, and disease identification.
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

Spread of cassava viral diseases: Infected planting materials can contribute to the spread of CMD and CBSD, creating challenges for national cassava production and phytosanitary management.
Inadequate certification frameworks: Existing seed regulations may not provide sufficiently developed procedures for certifying cassava planting materials.
Weak regulatory oversight: Limited inspection capacity and inconsistent quality control can make it difficult to verify the health and quality of planting materials at different stages of the seed system.
Insufficient digital monitoring: Paper-based or fragmented records can limit the tracking of seed production, field inspections, certification, and distribution.
Limited access to certified seed: Weak formal seed systems can leave farmers dependent on informal sources with uncertain varietal identity and phytosanitary status.
Barriers to inclusive seed-sector development: Small-scale and community-based seed producers may lack clear pathways, training, or institutional support to participate in regulated seed production.
Cassava-specific certification frameworks: Governments can develop or adapt national seed certification guidelines to address the particular requirements of cassava planting materials.
Institutionalized inspection and quality control: National regulatory agencies can oversee seed inspections and enforce standards throughout the seed production chain.
Digital regulatory monitoring: Tools such as Seed Tracker can support seed field registration, inspection records, certification management, and traceability.
Community-based QDS systems: Governments can establish or strengthen quality-declared seed approaches to broaden participation in quality seed production and improve access at local level.
Certification labeling: Electronic or other suitable certification labels can help identify seed categories and communicate certification status to farmers and buyers.
Policy and institutional strengthening: Governments can update seed policies, train inspection officers, and coordinate stakeholders to establish a functional and inclusive cassava seed quality management system.
The Cassava Seed Quality Management System offers a structured approach to ensuring the availability of clean, certified planting material, thereby improving national cassava productivity, promoting gender inclusion, and supporting climate resilience. It aligns with key national priorities and contributes directly to SDGs 1 and 2.
To effectively integrate this system into national agricultural programs, the following steps are recommended:
This approach not only strengthens seed system governance but also positions cassava as a reliable, high-performing value chain within national agricultural transformation agendas.

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.
