GCP21 Cassava Chain

GCP21 Cassava Chain

GCP21 Push-Pull Concept

Trigger, Organize, stimulate R&D at the global level: looking for gaps

Invest, transfer modern science into cassava, inviting top labs in AICs

Catalyze, Organize and set-up Cassava Projects: look for funding opportunities

Steer communication on cassava through thematic meetings, global meetings, databases, websites, publications…

What Will GCP21 Do?

Relations GCP21 - RTB Creation of the GCP21 Secretariat at CIAT with participation of RTB Creation of a Technical Advisory Group ; RTB, CIAT, IITA, representatives from Africa and Asia, Embrapa Strengthen relations between GCP21 and RTB by participating in planning and strategic meetings of RTB, and by co-organizing thematic meetings on cassava GCP 21 will be a Partnership Platform for RTB which will contribute to mobilizing advanced research and development players in the world

Can we prevent CBSD to reach West Africa?

Can we decrease the impact of cassava viruses in Africa?

Can we prevent CBSD and CMD to spread in the rest of the world?

Declaring War on Cassava Viruses in Africa

3- Cassava-base feed system – RTB, WF, LSF, HT 4- Cassava Academy – all CRPs and NARS

5- Cassava and the climate change - CCAFS 6- Cassava seed system delivery – RTB, HT

Other Examples of Activities

Cassava is a halo-tetraploid plant 100% heterozygote ---

The next generation of improved varieties will have to go through modern breeding

--- The cassava community cannot afford to have efficient teams using the most advanced tools in many countries

--- We need GCP to build these tools, to update them regularly, to train scientists to use them in order to produce the next generation of performing material

--- Genome Selection – Double Haploids –

Deconstruction and Reconstruction of Heterosis

Collaboration with GCP

Co-Organize IBP Training Sessions ---

Organize awareness and technical meetings with scientists and donors

--- Initiate Proposals to develop or expand tools

--- Organize and develop in collaboration a

database with all phenotypic and genotypic information
