Involvement in the IAASTD Report
Dryden was one of six private sector representatives on the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD) Bureau (2004-2007), where he represented Emergent Genetics. The others were Harry Swaine (Syngenta), Steve Parry (Unilever), Rob Johnston (Cargill, USA), Momtaz Chowdhury (Agrobased Technology and Industry Development, Pakistan), and Gisele Lopes D'Alme ida – Interface Senegal.
- "Sam Dryden and Rob Johnston withdrew for “pressures of work / personal circumstances ” reasons at the outset. Steve Parry withdrew in 2006 following an illness and subsequent retirement from Unilever. Gisele Lopes only attended one meeting. The Private Sector was represented on Bureau sub-Committees as follows:
- Harry Swaine – Finance; Steve Parry – Author Selection; Momtaz Chowdhury – Communication.
- "Several appeals were made to the Secretariat to replace the diminished Private Sector representation – all were ignored or rejected. The result being that Swaine and Chodhury were the only private sector representatives with the latter remote and without any support infrastructure at her base."
