Water security appears to be the subject of many search engine queries in North America. Although other countries do not appear on the regional interest list this does not indicate necessarily an absence of queries but rather a low volume of queries. Qualitatively, it seems that interest in water security has been fairly stable during the last year.
Food security was clearly of concern during the previous 12 months in Kenya, Nigeria, South Africa, India, and Australia as well as in North America and the UK. There appears to be a recent upsurge of interest in food security.
In the context of these regions, the WaterProducer-Greenhouse™ may be investigated as a possible water-plus-food-security solution for small tropical islands, with access to deep cold ocean water, associated with especially India (Lakshadweep, Andaman Islands, Nicobar Islands), Australia (Coral Sea Islands), and USA (SE Florida, Florida Keys).
