This document discusses cassava production globally and proposes a Global Alliance for Cassava Improvement. It notes that cassava is produced in 105 countries across Latin America, Africa, and Asia, with Africa producing 30% of global cassava on just 3.5 million hectares. Productivity varies greatly between regions. The document proposes forming a Global Alliance to address issues like increasing cassava productivity and yields, which have risen overall but vary between countries. It presents data on increasing cassava production and yields in various countries and regions over time. The Alliance would work to improve cassava through initiatives like addressing viral diseases, climate change impacts, breeding programs, and increasing capacity in producer countries.

14. GCP21 Cassava Chain

15. GCP21 Push-Pull Concept

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

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
