African Cassava Agronomy Initiative is a 5-year project funded by the Bill and Melinda Gates foundation to increase the availability of appropriate and affordable technologies to sustainably improve cassava productivity in the short- and long-term

Project Countries



Build the approach into national research systems to guarantee continued pipeline for technology development


Increase the scope, relevance, cost-effectiveness and speed with which agronomic research data are generated


Provide a systematic, geospatial assessment of attainable yields and yield constraints


Warrant that research results are utilised by ‘last mile’ service providers

The Project

ACAI follows a demand-driven approach, responding to needs identified by development partners to develop technologies that fulfil those needs. The project develops technologies in the context centered around 6 use cases

A fertilizer blending decision support tool for the fertilizer industry

A site-specific fertilizer recommendation tool for extension agents

A best planting practices tool for extension agents or farmers

A cassava intercropping decision support tool for extension agents or farmers

A staggered planting decision support tool for year-round cassava root supply to the processing

Practices for higher root starch yields for processing industry.

Implementation Strategy

The project is organized into 6 work streams that are complimentary and interdependent to each other spread through the project tenure

  • WS1: Strategic research on cassava growth dynamics, nutrient and water requirements

  • WS2: Geospatial modelling and development of Geo-information systems to support tool development

  • WS3: Development of decision support tools for the 6 use cases

  • WS4: Facilitation of the use of the decision support tools by the target clients

  • WS5: Capacity development and institutionalization at national system level

  • WS6: Project governance, management, coordination, monitoring, evaluation and learning
