THE FUTURE OF FOOD


Each is full of nutrients and
just might survive the
changing climate
By Anna Gibbs

Millet
SOURCE OF: Carbohydrates, protein, minerals (potassium,
phosphorus and magnesium)
USES: Whole grain; gluten-free flour, pasta, chips, beer
The United Nations has declared 2023 the International Year
of Millets (a handful of varieties exist). Quinoa earned the
same honor in 2013, and its sales skyrocketed. First culti-
vated in Asia some 10,000 years ago, millet is a staple grain
in parts of Asia and Africa. Compared with wheat, maize and
rice, millet is much more climate resilient; the crop needs
little water and thrives in warmer, drier environments. Some
more good news: Millet is one of many ancient grains —
including teff, amaranth and sorghum — that are similarly
sustainable and resilient (not to mention capable of being
turned into beer).

Bambara groundnut
SOURCE OF: Protein, fiber, minerals (potassium,
magnesium and iron)
USES: Roasted or boiled; gluten-free flour; dairy-free milk
You’ve heard of almond milk and soy milk. The next
alternative at your coffee shop could be made from
Bambara groundnuts, a drought-tolerant legume native
to sub-Saharan Africa. Like other legumes, the Bambara
groundnut is packed with protein. And bacteria on the
plant convert atmospheric nitrogen into ammonia so
the groundnut grows well in nutrient-poor soil without
chemical fertilizers. A better understanding of the plant,
says Festo Massawe of Future Food Beacon Malaysia, could
pave the way for breeding programs to help the Bambara
groundnut become as popular as the soybean, a legume
that produces high yields but is less drought tolerant.

FOODS


N


o matter how you slice it, climate change will
alter what we eat in the future. Today, just
13 crops provide 80 percent of people’s energy
intake worldwide, and about half of our
calories come from wheat, maize and rice. Yet some of
these crops may not grow well in the higher tempera-
tures, unpredictable rainfall and extreme weather events
caused by climate change. Already, drought, heat waves
and flash floods are damaging crops around the world
(SN: 9/25/21, p. 16).
“We must diversify our food basket,” says Festo
Massawe. He’s executive director of Future Food Beacon
Malaysia, a group at the University of Nottingham
Malaysia campus in Semenyih that studies the impact of
climate change on food security.
That goes beyond what we eat to how we grow it. The
trick will be investing in every possible solution: breeding
crops so they’re more climate resilient, genetically engi-
neering foods in the lab and studying crops that we just
don’t know enough about, says ecologist Samuel Pironon
of the Royal Botanic Gardens, Kew in London. To feed
a growing population in a rapidly changing world, food
scientists are exploring many possible avenues, while
thinking about how to be environmentally friendly.
Consumer preferences are part of the equation as well.
“It does have to be that right combination of: It looks
good, it tastes good and it’s the right price point,” says
Halley Froehlich, an aquaculture and fisheries scientist
at the University of California, Santa Barbara.
Here are six foods that could check all those boxes and
feature more prominently on menus and grocery shelves in
the future.
