Halophyte Crops to Green the World’s Deserts | 19/10/14
by John Brian Shannon
What could be better than creating rich cropland out of the world’s desert regions?
It’s a tempting idea. Some 33% of the world’s landmass is covered with desert landscape and 40,000 miles of coastlines are adjoining deserts. Nothing but ocean, sun, and sand. But in those hostile regions, some prototype halophyte farming projects have scored significant successes.
Halophytes for human food, for livestock feed, and for biofuel production
Whether halophyte crops are grown for food (the ‘tenders’ or ‘leaves’ of the plant have a light nutty and salty taste) or to feed livestock (the stalks) or for biofuel production, growing these crops along coastal regions restores plant life to desert areas adjoining the ocean.
A land plan that grows halopyhtes food for humans/livestock feed and for biofuel production will produce the best economic result
“Integrating those two systems you get sustainable aquaculture that does not pollute the oceans and biomass that can be used for fuels” — Darrin L. Morgan
As a bonus in poverty-stricken lands, dried halophytes (branches/roots) can serve as an infinitely cleaner cookstove fuel than what is presently used in such areas — which is often dried livestock dung or expensive kerosene.
Halophytes are those crops which are salt-tolerant and can survive the blistering heat of the world’s deserts. Many of the crops we presently grow have salt-resistant cousins — all they need is trenches or pipelines to deliver the water inland from the sea.
Halophytes negate the need to remove the high salt content of ocean water which in itself, is a very costly proposition with desalination plants costing millions of dollars.
As halophyte farms become established they improve the growing conditions for non-halophyte plants
Most deserts are sand, which means all that is required to begin creating usable farmland is startup funding, farm machinery, a field plan and seeds, and of course, plenty of farm labourers.
Creating Wealth out of Sand and Seawater
Some of the poorest places on the planet are also ‘rich’ in deserts and are located near plentiful salt water resources, making them suitable candidates for halophyte farming. Economic benefits for poor countries are stable growth, lower unemployment, better balance-of-trade and less reliance on foreign food aid programmes.
If you can grow your own food at low cost, why buy it from other countries?

Other successful examples exist in other coastal regions around the world
Helping to mitigate global sea level rises due to climate change, creating powerful economic zones out of desert, seawater and labour, lowering unemployment in poverty-stricken nations, removing carbon from the atmosphere and returning it to the soil, all while dramatically increasing crop and seafood production are all benefits of growing halophytes in coastal desert regions of the world.
Stage I Coastal Desert transformation
The first 25,000 miles of coastal desert out of a grand total of 40,000 miles of coastal desert globally can be converted to this kind of farming simply by showing up and using existing simple technologies/cultivation methods and seed varieties.
Stage II Coastal Desert transformation
The other 15,000 miles of coastal desert regions could be viewed as Stage II of this process after the best candidate areas become fully cultivated, as these secondary regions may require more capital investment for conversion due to their somewhat more inland locations.
Huge opportunity awaits early investors in this rediscovered agricultural market. Cheap land, free ocean water, low cost seeds and local labour, and a reputation as businesspeople who can solve local problems add value and employment to poverty-stricken regions, and lead growing nations forward, look promising for seawater/halophyte farming owner/operators and investors.
