The study was conducted by researchers at the University of Sydney and the Stockholm Resilience Centre. It looked at social networks and the use of fertiliser in 30 rural, cocoa-producing villages in Sulawesi, Indonesia, to examine how innovative and sustainable farming practices are adopted among communities. “In the case of fertilisers, this is a problem because too much can threaten the environment and too little can impact food security,” says Petr Matous. These findings have implications when designing interventions for sustainable farming practices. The authors caution against programs that elevate a select group of farmers that have been chosen simply because they have been the target points for previous interventions.
