16. 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?
17. 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
21. 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?

Other Examples of Activities
29. 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
30. 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
Collaboration with GCP
