This working paper reviews the experiences of the Challenge Program on Water and Food (CPWF) with 14 “small

grants for impact” that were contracted in early 2006 and operated for periods of 12 to 18 months. For a total

investment of under US$1 million – less than the equivalent of a typical 3-5 year CPWF research for development

project in Phase 1, the small grant projects made significant contributions to identifying water and food technology

for specific end users (thus showing the potential of CPWF research in general); to better understanding of

The project validated and disseminated a large number of improved rice-based cropping systems technologies suited to upland agro-ecologies. These improved technologies have good potentials to raise the productivity of water, land, and labor. The innovative strategies employed by the project including the paradigm of landscape management, multi-institutional partnership, multidisciplinary teamwork, farmer participatory approach to technology validation, and community-based seed production led to successful generation and dissemination of technologies.
