Modelling Water Nutrient Pollution with Stakeholders Involvement
Participatory processes are useful for improving multi-level environmental governance. In the case of Integrated Water Resource Management (IWRM), participatory watershed modelling has been proposed as a mean to address the complex issue of water management under contrasting interests. In fact, including the stakeholders perspectives, participatory watershed modelling allows to consider the local knowledge and to facilitate the acceptance of scientific modelling outcomes. This improves the dialogue between science, policy and society and can contribute to legitimate the decision making process. In the STRIVER project (EU FP6 SUSTDEV-2005-3.II.3.6: Twinning European/Third countries river basins), we explored the potential of integrating the stakeholders view in modelling water nutrient pollution. We analysed water pollution issues in two river basins, the Glomma in Norway and the Tungabhadra in India, in the context of a twinning exercise, by applying the same modelling tool, the model SWAT (Arnold et al., 1998). In the modelling process, we included the knowledge derived from the dialogue with local stakeholders during the annual stakeholder meetings organised by the project. In particular, we tried to articulate the interaction through three sequential phases of the modelling exercise: (1) modelling set-up, (2) modelling validation and (3) analysis of scenarios (Figure 1). This approach has proven to be suitable to support IWRM, addressing the specific issue of water pollution by nutrients (Grizzetti et al., 2009), and have resulted particularly appropriate for the Norwegian case in view of the forthcoming implementation of the Water Framework Directive (WFD) (Barkved et al., 2009). Here the physically-based model SWAT was applied in the Hunnselva and Lena catchments, which are part of the Glomma basin, to represent the actual pressures of nitrogen and phosphorus on water and predict the potential impact of future scenarios. The modelling study was developed including the inputs from the local stakeholder group participating in the STRIVER project, and the scenarios were focused on the implementation of measures to reduce nutrient losses to water and on agricultural changes to produce more profitable crops. This chapter presents the results of this research activity according to the three steps shown in Figure 1, with a particular emphasis on the biophysical modelling results, and discusses the relevance of stakeholders involvement in the process. ; JRC.H.1-Water Resources
