Enhancing cassava yields and quality for greater food security in Africa.
Cassava varieties with higher dry matter and starch content in their roots, significantly impacting their value for farmers. This addresses the limited availability of suitable varieties in Sub-Saharan Africa, leading to better economic yields and increased food security. Through selective breeding and resistance to pests and diseases, we've created cassava with 40% to 45% dry matter and 80% to 95% starch. These improved roots can be used fresh or processed into high-quality flour or starch, serving as crucial ingredients in various industries. This technology not only benefits small-scale farmers but also provides a cost-effective source of essential ingredients for commercial agri-businesses.
This technology is TAAT1 validated.

The cassava varieties with high dry matter and starch content technology contribute significantly to various aspects of sustainable development. By enhancing the economic empowerment of women through increased household income and resource access, promoting their roles in agriculture this technology addresses critical farmers challenges.
To integrate this cassava technology into your project, consider the following activities and prerequisites:
Estimate the quantity of cassava roots required for your project, considering a technology cost per unit.
As the technology is available in Benin, Ivory Coast and Nigeria, include the delivery cost to the project site, accounting for potential import clearance and duties. Consider a team of trainers for training and support during project installation, including costs for training and post-training support.
Develop communication support for the technology, such as flyers, videos, and radio broadcasts, to raise awareness.
For optimal results, associate this technology with Disease resistant cassava varieties, Golden cassava varieties, Integrated weed, pest and soil management system (GAP), Seed bulking for cassava multiplications.
To implement this technology in your country, explore collaborations with agricultural development institutes and seed multiplication companies for effective implementation.

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.

Enabling Environments for Sustainable Regional Agriculture Extension (ENSURE)
Project funder: African Development Bank & East Africa Community
Planned Budget: USD 13.14 million
Location: East African Community (Burundi, DRC, Kenya, Rwanda, South Sudan, Tanzania, Uganda)
Planned duration: 2024–2027
Deployment means: On-farm demonstrations, training, digital tools (SMS, IVR, video, radio, pictorial guides), bundled inputs + advisory services, Training of Trainers (ToT)
Project main implementer: East African Community (EAC)
Project Description: Strengthen agricultural extension systems using digital tools, private-sector approaches, regional coordination, and multi-commodity focus (maize, cassava, rice, drought-resilient crops).
Objective: Promote regional extension, enhance advisory services, scale climate-smart technologies, build sustainable private sector–led extension systems, strengthen policy and regulatory frameworks.
Expected outcome: Increased adoption of improved technologies, improved farmer productivity and profitability, enhanced access to quality inputs and pest management solutions, strengthened resilience to climate and pest risks, regional market integration, job creation for youth and agripreneurs.
Figures of adoption: Target 3 million farmers reached over 4 years, digital extension pilots in 7 EAC states, training of extension agents, lead farmers, cooperatives, and youth agripreneurs, rollout of Pest Information Management Systems (PIMS).

The United Nations Sustainable Development Goals that are applicable to this technology.
Variety Selection: Choose the enhanced cassava variety suitable for your specific conditions and context in the value chain.
Acquire Planting Material: Purchase high-quality planting material from reputable seed companies for initial planting.
Planting and Cultivation: Use the acquired planting material to establish your cassava crop. Ensure the planting materials are free of disease symptoms when transferred to the field.
Planting Technique: Depending on rainfall conditions, plant cuttings horizontally in dry climates and vertically or angularly in humid areas with high precipitation. Cover them entirely with soil.
Soil and Fertilizer Management: Adhere to recommended soil and fertilizer management practices for your specific growing area and conditions to achieve high root yields.
Monitoring and Maintenance: Keep an eye on the cassava crop for signs of pests, diseases, and nutrient deficiencies. Address these issues promptly to maintain healthy growth.
Harvesting: Harvest the cassava roots once they have reached the desired maturity and size, typically around 8-12 months after planting.
Post-Harvest Handling: Handle the harvested roots with care to avoid damage. Store them in a cool, dry place to prevent spoilage.
Processing (Optional): If needed, process the roots into flour or starch for various applications in food, pharmaceuticals, packaging, or industrial products.
Seed Management (Optional): If you're interested in multiplying the improved varieties, follow recommended seed management practices for certification and compliance.
Market Linkages (Optional): Establish connections between seed suppliers, cassava growers, food processors, and consumer groups to create demand for cassava-based products.
