How does the government and experts share knowledge with ordinary people that are also the key actors in environmental water governance? This chapter examines the various communication practices in the Saemangeum Water Project, a national government-led development initiative that required cooperation from local government actors and farmers. Interviews with local government officials and farmers revealed the reasons for the breakdowns in communication that included non-communication and tokenistic communication, resulting in farmers distrusting the government and seeking alternative information sources. The research showed that while government actors easily engaged in knowledge communication for integrated water management with other government actors and experts, they struggled communicating with farmers. This was confirmed by local government actors who were expected to collaborate with farmers but failed to do so. The findings suggest a need to engage mediators to avoid the kind of communications breakdowns that not only excluded the farmers but disrupted water governance.
