ME-CASS: Cassava Seed Monitoring System

Making Cassava Seed Systems Work Better

ME-CASS supports national seed agencies, ministries of agriculture, and public research institutions in tracking cassava seed systems. It monitors the release, certification, and distribution of improved cassava varieties, helping ensure that farmers receive high-quality, approved seeds.

The tool also supports policy planning by providing real-time data on seed flows, variety adoption, and the performance of seed producers. This helps improve accountability, enforce regulations, and guide investments to strengthen national seed systems.

This technology is pre-validated.

Problem

  • Loss of varietal identity in the field: Improved cassava varieties introduced through government programs often lose their names and are re-labeled as local types. This undermines the value of public investments in research.
  • Weak documentation from certification agencies: Without a proper monitoring tool, national agencies struggle to document which seeds are certified and where they are distributed.
  • Limited feedback on seed adoption and system progress: Governments lack tools to evaluate whether improved seeds are reaching farmers and performing as expected.

Solution

  • National seed traceability system: ME-CASS supports the government to document each step in the seed chain, backed by data from the national certification agency.
  • Real-time visibility into seed delivery: The system provides evidence on where certified seeds are being produced and planted, supporting enforcement and planning.
  • Monitoring adoption and system health: ME-CASS allows regular tracking of how seed systems are evolving—variety change rate, seed quality, and system performance. 

Key points to design your project

To successfully integrate ME-CASS into a national seed system project, governments need a practical, well-structured approach. ME-CASS is not just a software—it’s a management tool that requires coordination, data discipline, and stakeholder engagement. Below are the core elements a government-led project must include to adopt and implement the technology effectively.

Below are practical recommendations to guide project design:

  • Start with a functional data system:
    Choose a reliable platform to host the ME-CASS database. If national systems already exist, integrate ME-CASS with them rather than starting from scratch.

  • Invest in a skilled monitoring team:
    Build a core team with basic digital skills and a clear mandate. Use existing staff from seed certification agencies or agricultural departments to reduce costs.

  • Define clear indicators from the start:
    Agree early on what the system should track—volumes, variety names, producers, and adoption zones—and set realistic targets for each.

  • Make stakeholder engagement routine:
    Include all key seed actors (breeders, regulators, producers, and extension services) in project meetings and ensure they contribute data regularly.

  • Pilot before national rollout:
    Test the system in 1–2 regions for a full season. Use the pilot to adjust tools, build user confidence, and document lessons for national scaling.

  • Budget for basic equipment and connectivity:
    Provide laptops or tablets and ensure internet access where needed. Offline data collection options should be considered in remote areas.

  • Link to government planning cycles:
    Align ME-CASS reporting with existing monitoring systems to ensure sustainability and avoid duplication.

  • Plan for future integration:
    Design the project with flexibility to extend the monitoring system to other vegetatively propagated crops like yam, sweetpotato, or banana.

The United Nations Sustainable Development Goals that are applicable to this technology.

Sustainable Development Goal 1: no poverty
Goal 1: no poverty

By improving seed system efficiency and traceability, ME-CASS supports smallholder farmers' access to high-quality cassava varieties, helping increase productivity and income.

Sustainable Development Goal 2: zero hunger
Goal 2: zero hunger

Ensures reliable delivery of improved cassava varieties that enhance food security and reduce seasonal food gaps.

Sustainable Development Goal 3: good health and well-being
Goal 3: good health and well-being

Indirect contribution through support to nutrient-rich cassava varieties and reduction of unsafe planting materials.

  • Set up the system:
    Create a database using digital tools like ME-CASS, spreadsheets, or other software to store seed system data.
  • Form a monitoring team:
    Identify and train a small national or regional team to manage data collection, interpretation, and reporting.
  • Define key indicators:
    Decide what to track—e.g., seed volumes, variety names, seed producer performance—and set target values for each.
  • Engage key stakeholders:
    Involve researchers, seed producers, certification agencies, and farmer organizations to support data collection and system use.
  • Collect and analyze data:
    Gather field data regularly, update the system, compare progress with targets, and provide feedback to actors.
  • Run a test season:
    Pilot the system for one full cropping season to test data flow, accuracy, and engagement.
  • Scale and review:
    After validation, roll out the system fully and schedule annual reviews to refine and improve performance.
  • Expand to other crops (optional):
    Once ME-CASS is established for cassava, adapt it to other vegetatively propagated crops like sweetpotato, banana, yam, or potato.
