MAL04 Causal loop diagrams for the Charente River basin and its coastal zone (France)
<p>This dataset includes the causal loop diagrams (CLDs) developed by the H2020 COASTAL project’s MAL #4 for the Charente River basin and its coastal zone. These CLDs represent the functioning of the territory in a systemic way, highlighting its main components and interactions among them. The CLDs are the result of multiple sectoral and multi-actor workshops during which stakeholders from different sectors discussed and collaborated to establish a common vision of the land-sea system. The CLDs concern the whole territory and some specific sectors.</p>
MAL04 Territorial development scenarios for the Charente River basin and its coastal zone (France)
<p>This dataset includes the territorial development scenarios developed by the H2020 COASTAL project’s MAL #4 for the Charente River basin and its coastal zone. These scenarios were co-designed with local stakeholders to depict possible futures of the territory. “Towards a desirable future” represents the implementation of the business roadmap also designed in collaboration with stakeholders to achieve a desirable and sustainable future. “Improving current trends” describes the expected evolution of the territory if current efforts are maintained without significant innovation. “Towards a fragmented territory” illustrates a negative development of the territory, exacerbating current issues and inequalities. Each scenario consists in a narrative and in a set of values attributed to the decision variables of the MAL #4 system dynamics model. These values are converted into time-series to simulate the scenarios (cf. data_scenarios.xlsx in <a href="https://doi.org/10.5281/zenodo.7075123">https://doi.org/10.5281/zenodo.7075123</a>).</p>
