PhD defence, Monday, 13 June 2022. Raphael Filippelli.

Excess nutrients coming from agricultural fields can cause oxygen depletion in coastal waters, with detrimental effects to aquatic biodiversity and fish stocks. During his PhD studies, Raphael Filippelli has conducted environmental-economic modelling research on how to mitigate emissions from agriculture to coastal waters in cost-effective ways. Raphael has investigated the potential of combining land-based mitigation by agricultural farmers and mitigation by mussel farmers through marine-based mussel production and harvesting. Raphael Filippelli has used mathematical modelling techniques and combined environmental and economic data to identify efficient options. Furthermore, Raphael has explored the potential of using a SMART market approach   to incentivize cost-effective implementation. The research presented in the thesis has contributed to a national assessment of the potential to use mussel farming to meet the water framework directive targets for good ecological status of coastal waters. The assessment has tested the integrated model as a decision support tool to assist environmental agencies in regulation of agricultural emissions.

The PhD study was completed at the Department of Environmental Sciences, Faculty of Technical Sciences, Aarhus University.
