Integrated management of the valorization of liquid and solid waste - case study of Sousse area, Tunisia

We propose to explore plausible new scenarios of waste valorization for agriculture purposes based on a case study in Tunisia. The originality of the proposal, compared to existing investigations on water “reuse”, is to consider both liquid and solid wastes as common sources of nutrients for crops to be refined, and adopt an integrated vision at the scale of a territory (Sousse area) which is famous for olive growing. We aim at collecting relevant data in a first step, in order to compare it with current practices and to propose management scenarios in a second step. Approaches based on modelling, numerical simulations and spatial analysis will be also assessed for the elaboration of decision making tools in future projects. The overall philosophy of the project is to deploy a generic approach to the issue. The potential solutions will be discussed and presented to local stakeholders, specialists and practitioners in a forum. Finally, this project aims to initiate a fruitful collaboration between multidisciplinary partners with the intention to continue beyond this seed project.
