The Business Roadmap and Policy Recommendations (BRM) represents 14 solutions for sustainable development of the Mar Menor and surrounding Campo de Cartagena that were developed during an extensive co-design process (workshops, expert interviews, online questionnaires) with representatives from all relevant sectors involved. A full description of the BRM, its co-development, and the modelled impacts on Key Performance Indicators of sustainability can be found in Martínez-López et al (2022). The model parameter time-series in this dataset indicate if and when a solution is turned on or off between 1964 and 2070 based on preferences indicated by stakeholders. These time-series represent input parameters for the System Dynamics model of the socio-ecosystem of the Mar Menor-campo de Cartagena developed in the COASTAL project and that is used to quantify impacts on key performance indicators of sustainability. This System Dynamics based model, developed by Martínez-López et al (2022) can be consulted here. The Business Road Map and Policy Recommendations (BRM) consists of the following 4 milestones and related 14 solutions: (I) Rural ecotourism: 1. The promotion of rural ecotourism activities. (II) Coastal ecotourism: 2. The promotion of coastal ecotourism activities. (III) Sustainable agriculture: 3. Implementation of nutrients, soil, and water retention measures 4. Reduction in fertilizer use 5. Denitrification of brine wastes from groundwater treated for irrigation 6. Decrease in agricultural water demand per hectare (i.e. 10% of decrease by default in the model) (IV) Integrated sustainable management: 7. Control of the extension of irrigated areas 8. Promotion of environmental education 9. Control of the number of groundwater wells (i.e. maximum 500 wells by default in the model) 10. Promotion of small (<10MW) (agro)photovoltaic facilities 11. Surface water pumping from the Albujón ephemeral stream 12. Control of other point sources of pollution to the lagoon 13. Groundwater pumping and treatment 14. Increase in sea water desalination amount (twice the BAU value)
