Unintended area expansion effects possible! Timing, sequencing: Invest steadily, avoid pro-cyclical action and price movements; synchronize R&D investment with other measures (water pricing, water use efficiency); take into account the long gestation periods. Organize/co-ordinate R&D: Combine expertise of the private sector with needs and constraints in developing countries: PPPs, humanitarian use licenses, etc Summary and conclusions
