To guarantee the long-term sustainability of the ‘ribeiras’ it is preferred not to abstract more (brackish) groundwater, also for a biosaline project. The figure below shows examplatory salinity measures from the groundwater assessment

Seawater-based agriculture seems a realistic option in areas that have become unproductive or have marginal agricultural production due to salinisation and where fresh water for agriculture is scarce.

The viability study indicates that the development of biosaline agriculture based on seawater seems interesting for Cape Verde.

The economic value of seawater fodder crops is evident for Cape Verde; however, a number of other species can also be considered, such as tree species, species for landscaping. 

Conclusion
Before taking next steps it is wise to first develop a 1 - 2 ha test area, during a period of three years:
• A test area enables to test promising plant species in the Cape Verdean environment on their potentials as agricultural crops (yields, nutritional values, etc).
• A test area gives the opportunity to introduce the new technology to the local population, train farmers and Cape Verdean technicians (INIDA). It will also provide a basis for active collaboration, community action and interaction, awareness and ownership.
• A test area will provide the basis for an assessment of the environmental impact of seawater-irrigated agriculture. It also provides opportunities for necessary adjustments on a small-scale basis.
