Citizen engagement is the involvement of citizens in civic processes, such as decision-making, policymaking and community issue resolution. In order to guarantee a society’s capacity to undertake long-term visions and to transform such plans into reality, co-creation and co-implementation are vital. The involvement of citizens not only in socio-political processes but also in the tasks of the monitoring and observation of environmental factors is becoming increasingly recognised as being of great importance both by public administrations and research institutions. However, it is a concept that is often misinterpreted by the very stakeholders who would most benefit from its correct implementation.
