Trade free of barriers facilitates technology transfer. Trade has exploited comparative advantages among climates and will continue to do so if climate changes. Free movement of innovations, knowledge and trained work forceswill speed technology transfer. This was demonstrated in th past, during the Green Revolution which showed the power of free movement of money, technicians, genes and information. As governments and donors have economised, business has stepped forward in research and innovation, but merely focusing on profitable areas.
Education lies at the heart of technological transfer.
The public role in education is pre-eminent and must be supported. Policies of practical demonstration have proven the most helpful form of education. Private business can announce technology in advertisements or demonstrate it at fairs. Governments have a role in monitoring claims and educating broadly. Although the transfer of new varieties proceeds quickly and easily, transferring systems of management requires persistence.
