CORIGAP: Closing Rice Yield Gaps in Asia SDC supports the International Rice Research Institute and national research and extension partners in six countries in Asia (China, Indonesia, Myanmar, Sri Lanka, Thailand, Vietnam) to develop quantitative tools and methods to optimize the sustainability of irrigated systems in order to enhance regional food security while minimizing the environmental footprint of rice production. Through this contribution, Switzerland has initiated the development of sustainable rice production indicators which are now adopted by more than 100 private and public organisations.
