This article in The Conversation gives a useful update about the water crises affecting people in the Caribbean Islands. The Water-from-Air Greenhouse Project was very active a bit over twenty years ago. The Viability Study reports produced for the Canadian International Development Agency were second-to-none. In my opinion they remain a valuable collection of knowledge about how to establish a commercial water-from-air irrigated greenhouse on a small tropical island. Sadly, the necessary level of interest and funding never materialized so not even a pilot installation was built. Inertia from so many angles stifles innovation! In the proverbial alternate universe there would now be several WaterProducer-Greenhouse™ installations to help alleviate the water crises discussed in the article.

From Wikipedia: Canadian International Development Agency

"The Canadian International Development Agency (CIDA) was a federal Canadian organization that administered foreign aid programs in developing countries. The agency was merged into the Department of Foreign Affairs in 2013 by the federal government under Prime Minister Stephen Harper."

"CIDA was formed in 1968 by the Canadian government under Lester B. Pearson. CIDA reported to the Parliament of Canada through the Minister for International Cooperation."

This interesting article in EOS, published by the American Geophysical Union (AGU), has insights about the development and deployment of OTEC that are likely to apply also to water-producing greenhouse technologies.

The January 2021 issue of the Caribbean Agro-climatic Bulletin of the CariSAM presented these interesting maps. Highlights: (1) Dry spells are probable for The Bahamas, Cayman Islands, and Cuba. (2) Long-term drought may occur in Grand Cayman and St. Kitts. For details, visit ​https://rcc.cimh.edu.bb/carisam-bulletin-vol-4-issue-8-january-2021/

A recent article about Seawater Air-Conditioning (SWAC) contains knowledge applicable to the design of the WaterProducer-Greenhouse™.

The WaterProducer-Greenhouse​™ design is intended for tropical small islands, many of which are small island developing states. Here is a link to the official United Nations list of small island developing states.

Because the WaterProducer Greenhouse Project is an appropriate technology for small island developing states, this new series by DEVEX is quite relevant for visitors to this site.

A recent online article by Dr. Fernando Pérez Monteagudo (Professor at the Centre for Hydraulic Research, Havana, Cuba) in Water & Wastewater International explained how desalinated water supplements the rainwater fed drinking-water system on Grand Turk.

Sustainability must be the goal of water resources management in small islands, and Grand Turk, the capital of Turks and Caicos Islands, is carefully preserving its complex water supply system fed mainly by rainwater and supplemented by desalination. Read more...
