ABOUT CTA The Technical Centre for Agricultural and Rural Cooperation (CTA) is a joint international institution of the African, Caribbean and Pacific (ACP) Group of States and the European Union (EU).

Its mission is to advance food and nutritional security, increase prosperity and encourage sound natural resource management in ACP countries. It provides access to information and knowledge, facilitates policy dialogue and strengthens the capacity of agricultural and rural development institutions and communities. CTA operates under the framework of the Cotonou Agreement and is funded by the EU.

ABOUT FARA The Forum for Agricultural Research in Africa (FARA) is the apex organisation charged with the strategic role of coordinating and advocating for agricultural research and development in Africa.

FARA weaves together key networks and stakeholders on the continent and globally to reinforce the capacity of Africa to improve its agricultural science and innovation for food and nutrition security and poverty reduction. FARA serves as the technical arm of the African Union Commission (AUC) on matters concerning agricultural science, technology and innovation. FARA provides a continental forum for stakeholders in AR4D to shape the vision and agenda for the sub-sector and to mobilise themselves to respond to key continent-wide development frameworks, notably the Comprehensive Africa Agriculture Development Programme (CAADP) in which it helps to implement and sustain the momentum of CAADP especially in harnessing knowledge, information and skills (KIS) for Africa’s agriculture development. FARA delivers on its mandate through three mutually-inclusive options of envisioning its strategic direction, integrating its capacities for change and creating enabling policy environment for implementation. And some key initiatives are implemented to bring about specific results in these broad areas.
