Scaling Suitable Sustainable Technologies (S3 Cambodia)


Building on our prior research in Cambodia, this project seeks to bring three sustainable intensification technologies to scale: vegetable grafting, cover/relay crops, and wild gardens.


USAID Feed the Future Innovation Lab for Collaborative Research on Sustainable Intensification (SIIL)

Project Activities

The Scaling Suitable Sustainable Technologies (S3-Cambodia) project builds on the 2015-2020 WAgN project to scale suitable and sustainable technologies to farmers in Cambodia. S3-Cambodia will scale three of these technologies: vegetable grafting, post-rice secondary cropping, and wild gardens. These innovations promote the diversification and resilience of smallholder systems by introducing new sources of income and nutrition during seasonal “food gaps,” across different agricultural spaces and serving different functions in livelihood strategies. Vegetable grafting and wild gardens also contribute to value chains that have traditionally engaged women in Cambodia. S3-Cambodia seeks to achieve scalable and sustainable solutions by working with agricultural groups and secondary schools to promote these market-oriented technologies.
