Abstract

That the System of Rice Intensification (SRI) was developed inductively, from observations and experimentation without hypotheses or a priori assumptions, has been both a strength and a weakness for this agro-ecological innovation. On the plus side, Henri de Laulanié’s empirical construction of SRI in Madagascar some four decades ago is benefiting tens of millions of rice-producing households in over 60 countries now. Further, it produced important new knowledge for rice production, some of it counter-intuitive.1 For example, Laulanié established through observation and in-field experimentation with farmers.
