Dear symposium Participant

We welcome you to the First Post-Harvest Innovation Programme symposium.

reflecting on the achievements of the past and setting the trend for future development in postharvest innovation, the symposium aims to bring together the enablers of innovation from industry, r&D organisations and policy development institutions, among others.

the Post-Harvest Innovation Programme is vital in promoting r&D cooperation towards market-driven innovation, promoting talent cultivation for the industry, and in globalising the south african postharvest innovation community. these are critical in ensuring a competitive Fresh Produce export Industry.

It is an honour and privilege to host you, and we believe that your participation and contribution will enhance the value of the Post-Harvest Innovation Programme.

yours sincerely,
