SRI is a set of practices based on single, widely-spaced, early transplants which are then grown under a water regime that alternates wet and dry periods and often uses organic fertilizers. Together, these practices lead to stronger plants and to systems which are much more water-efficient, especially when compared to rice grown under conventional methods.
It is claimed to lead to a doubling of yields and to halving the use of water. Even though many scientists question it, SRI has spread rapidly among farmers, and many more are enjoying higher yields every year.
Issue 29.1 of Farming Matters will look at this evident success, and explore the ways in which these practices have spread, from farmer to farmer, from country to country, and also from rice to other crops. We welcome contributions that unravel the “mystery” behind SRI.
What are the benefits that farmers see? What indicators do they use to measure results? What extension or communication approaches are followed? How are farmers adapting it to their local context and conditions? What is the role of scientists, researchers and politicians? And why do scientific doubts remain even though more and more farmers are adopting it?
Building on the SRI example, we will also look at the political and institutional support which is needed to ensure that farmers’ innovations and successes receive the recognition and support they deserve.
