Dubai scientists grow super crops that shrive in salty deserts

The United Nations estimates that food production must increase 60 per cent in thirty years to meet demand, while gains in crop yields are slowing.

(Bloomberg) --Scientists in Dubai are developing crops like quinoa that can thrive in the salty soils intruding into the world’s croplands. Winning over enough people to eat them is proving a greater challenge.

At an experimental farm within sight of the world’s tallest skyscraper, researchers at the International Centre for Biosaline Agriculture (ICBA) are trying to help farmers in the Middle East and beyond earn a living from unlikely plants known as halophytes. These plants, from trendy quinoa to obscure salicornia, flourish in salty and arid environments where staple crops like wheat or rice would wither.

Concerns about climate change, population growth, and the degradation of fertile farmlands add urgency to the work of ICBA, which runs on a shoestring budget of $15 million a year.

“You can see the disaster coming. I cannot understand why more people aren’t acting to prevent it,” says Ismahane Elouafi, ICBA’s Director General. Governments are reluctant to invest in new foods and remain tethered to staple crops that “are just too demanding on water.”

Through selective breeding, the non-profit research institute developed five varieties of quinoa -- a protein-rich, gluten-free grain that tastes like nutty rice -- that grow especially well in salty soil. The centre is introducing them in Egypt and Morocco.

Agronomists at ICBA cultivate a patchwork of sandy plots on the fringe of Dubai’s desert interior. A vault where the temperature is kept at two degrees Celsius (36 degrees Fahrenheit) safeguards the fruits of their efforts: 14,000 types of seeds from more than 250 plant species.

These seeds are enough for trial use, but a breakthrough to large-scale halophyte production requires government or business support. Planting a new crop is only the first step for ICBA, which operates projects in 28 countries from Senegal to Bangladesh and counts the US, Sweden and the UAE among its top donors. The centre has to transform laboratory wins into commercial successes.

Quinoa is often more expensive than wheat, and many people are unfamiliar with products made from it. To make headway in rural Egypt, ICBA organised cooking workshops for 120 women to train them to prepare food from salt-tolerant crops. Changing palates has proven difficult in other markets.

Wajih Syed, co-founder of Kinwa Foods, spent more than two years persuading farmers in Pakistan to plant ICBA-supplied quinoa seeds in salty soils. The grain can earn these farmers up to 20 per cent more profit than wheat, and some growers have started to cultivate it on land no longer fertile enough for traditional crops, he said. Yet the grain remains a niche product.

“Changing the eating habits of a thousand years is not an easy job,” Syed said. “I do not see quinoa becoming a staple food in Pakistan for at least the next decade.”

Many farms in the Middle East rely on underground water reserves for irrigation. Aquifers are rarely replenished in the arid climate, and as groundwater levels decline, the reserves become dense with salts that can kill traditional crops. In coastal areas, seawater often intrudes into diminishing aquifers, making salinity worse.

And still, this international organisation is struggling to drum up cash to develop crops the world needs.

“It’s so hard to fund-raise for research when you are in the UAE because the donor thinks you are swimming in oil money,” Elouafi said. “When they see these high skyscrapers and luxury and what have you -- the images of Dubai that are portrayed everywhere -- it’s super-hard.
