SRI Methodologies

The System of Rice Intensification, known as SRI -- le Système de Riziculture Intensive in French and la Sistema Intensivo de Cultivo Arrocero (SICA) in Spanish -- is a climate-smart, agroecological methodology for increasing the productivity of rice and more recently other crops by changing the management of plants, soil, water and nutrients.

SRI Principles

SRI methodology is based on four main principles that interact with each other:

  • Early, quick and healthy plant establishment
  • Reduced plant density
  • Improved soil conditions through enrichment with organic matter
  • Reduced and controlled water application

Based on these principles, farmers can adapt recommended SRI practices to respond to their agroecological and socioeconomic conditions. Adaptations are often undertaken to accommodate changing weather patterns, soil conditions, labor availability, water control, access to organic inputs, and the decision whether to practice fully organic agriculture or not.
