System of Rice Intensification (SRI): Growing more with less
Overview of SRI - Improving Rice Productivity and Achieving Water Savings
Duration: 12 minutes (Flash)
Target audience: This presentation is intended for policy and decision makers, managers of development projects, and stakeholders involved in agriculture, water resource and irrigation management.
Content Covered: This section focuses on the benefits and limitations of SRI application. Compared to the commonly known flooded rice production, successful applications of SRI have shown that farmers can raise their paddy yields by 50 to 100% or more, while using fewer farm inputs, especially water. While failed field trials also exist, it is important to note that SRI is still a ‘work in progress’ and evolving, and should be adopted to local conditions and traditions.
After a brief review of the six key elements of SRI, the benefits of SRI are discussed - increase in paddy yields, better rice quality, reduction in irrigation water use, and reduction in production cost. Constraints to implementing and scaling up SRI are also reviewed - psychological and technical barriers as well as farm labor.
With climate change, increasing variability of rainfall, and the growing competition for water and land, SRI offers a new opportunity for increasing the production value per drop of water and for reducing agricultural water demand.
