ASHC is part of  the IITA-led African Cassava Agronomy Initiative working specifically in Nigeria.

ASHC defines the four roles carried out by partners as:

  • Knowledge partners (K) with proven technologies, or practices, to share
  • Research partners (R) that work with the team to learn lessons and assess outcomes
  • Input partners (I) that are keen to establish sustainable supply chains for the required inputs – usually private sector
  • Delivery partners (D) using different media and/or interpersonal approaches to reach farmers

IITA has pulled together a diverse partnership including:


Role in the project 

  • Work stream 1: Research on cassava growth dynamics, nutrient and water requirements, and responsiveness to inputs comprises all strategic research activities essential to deliver on the outputs of work stream 3
  • Work stream 2: Development of geo-spatial cassava agronomy information base
  • Work Stream 3: Development of decision support tools
  • Work Stream 4: Use of decision-support tools by primary and other partners
  • Work stream 5: Capacity development of national institutions to engage in transformative cassava agronomy R4D
