Aquaculture and Bioenergy
In arid and semi-arid regions like the Arabian Peninsula, water is a scarce natural resource affected by salinity and other contaminants. In many of these marginal environments, improving water supply for human consumption and irrigation purposes requires desalination of groundwater. To date, approximately 15% of farmers in the Arabian Peninsula install small-scale reverse osmosis (RO) plants to desalinate groundwater for field crop irrigation. These plants produce highly concentrated brine which can be an environmental hazard if not disposed of safely.
Examine the costs and potential revenues, effectiveness, sustainability and scaling out potential of Integrated Aqua-Agriculture Systems (IAAS) in marginal environments as a means for safe brine reuse and disposal while improving farmers' income.
