Through sustainable agricultural development, the BV-lac project has disseminated techniques of conservation agriculture (CA), between 2003 to 2013. As defined by the FAO in 2008, CA has three principles: i) minimum soil disturbance, ii) soil protection by vegetation cover, iii) crop rotation and plant association, requiring a double paradigm shift on cropping pattern and on strategies. A survey conducted in 2013/2014 showed that during the project, farmers adapted CA techniques to their own constraints in a long learning process leading to a continuum of practices between conventional agriculture and CA through a recombination of knowledge.
