Wexford, Ireland3Ulster University, School of Geography and Environmental Sciences, Coleraine, UKMaintaining safe drinking water is of paramount importance for the health of individualconsumers and is a policy, regulatory and economic challenge for authorities at local andnational scales. In this context, agricultural activities are of great importance as they can be one of the largest sources of diffuse pollution and these have the potential to affect the quality of raw water sources. To enhance measures designed to achieve good water quality in Ireland, there is a need to integrate the views of different stakeholders and actors which are included with water quality issues in different sectors. Based on this objective, for this study stakeholders werecategorized into four groups: individuals, policy developers, researchers and regulators.Stakeholder views and opinions were collected through individual interviews and also within a workshop where they were asked to connect and weight (positively or negatively) the relationship among different indicators affecting water quality. Maps from the people of the same group were aggregated in order to compare the ideas of different groups. The designed maps were thenimported within Fuzzy Cognitive Maps software (gephi) to analyse and visualize the different ideas. This work is ongoing and results from this study will provide a transparent frameworkon the perceptions of different stakeholders about the indicators affecting water quality inIreland and suggest some scenarios to improve the interaction among stakeholders in future.
