Why you should care
This carbon-eating plant turns brown land green and also tastes good in a salad.
Climate Surprises: The consequences you never considered.
By Nick Dall
The Daily Dose
On a recent trip to the 630-square-mile Addo Elephant National Park,
dense thickets of spekboom (a fleshy shrub with purple stalks and leaves
like bloated ticks) made it hard to spot the elephants, lions and rhinos
that call this slice of paradise home. Driving home from the park,
however, I passed through mile upon mile of yellowed grassland dotted
with sheep and goats. Not realizing it then, my drive was actually a form of time travel.
Only 100 years ago, spekboom thickets covered a Connecticut-size
swath of Eastern South Africa. And ecologist Anthony Mills is hellbent
on turning back the clock. If successful, his mass planting project
could capture 750 million metric tons of CO2 — enough to offset
Germany’s annual carbon emissions and still be able to leave a tip.
Even better news: What spekboom can do for the Eastern Cape, another plant can do in your corner of the planet.
Since Addo Elephant National Park was opened in 1931, it’s been a
tale of two biomes for the Eastern Cape. Outside of protected areas,
overgrazing has created “a vast man-made desert” that’s resulted in
carbon losses greater than 100 metric tons per hectare, says Mills.
Which is why he is piloting a reforestation project that could allow
farmers to continue to graze livestock (or game), while also earning
annual carbon credits to the tune of $20 per acre.
This will be a boon for both the sheep farmers, whose ancestors
presided over the original deforestation, and the planet at large. Neil
Dodds, who farms on 25,000 acres near Jansenville, has been involved in
Mills’ pilot program since 2008. After spending five years experimenting
with planting methods and timing, Dodds had a 120-acre spekboom thicket
planted on his farm. Unfortunately the plants haven’t grown as quickly
as hoped, mainly because planting such a small thicket amid a sea of
brown has created a food magnet for the region’s freely roaming kudu.
The real miracle, however, is the world we live in. Every habitat has its own spekboom.
But Dodds remains positive. All that’s needed, he explains, is for
some company with a carbon emissions problem (i.e., any company) to give
him enough cash to plant and fence a significant swath of the
tall-growing succulent (or vetplant in Afrikaans, which means
“fat plant”). Once the plants take, Dodds could bring his sheep and
goats back — although, he confides, he’d probably switch to game
farming, which is more lucrative and more sustainable.
If Mills and Dodds have their way, huge swaths of the Eastern Cape
could be transformed from brown to green. What’s more, says Mills, “the
topsoil will come back, bees will thrive, groundwater will return, and
the climate will improve,” explaining that the spekboom forest will act
“like a giant air conditioner.”
Which makes you want to get out there and start planting spekboom
everywhere. But not so fast. While research has led to spekboom being
championed as a “wonder plant” by marketers and eco-leaning yuppies in
South Africa, Mills stresses that there are “a few very important
caveats.” First, the plant thrives in the hot, dry and frost-free
coastal plains of the Eastern Cape. Try growing it somewhere like New
Mexico — which gets just as hot and dry as Addo but is also susceptible
to frost — and you’ll struggle. (Luckily, agave plants are also adept
carbon munchers and tolerant of frost to boot.)
And yes, the plant’s ingenious design quirk allows it to
photosynthesize throughout the night, but that doesn’t mean it eats more
carbon than another plant of the same size. So, go ahead and grow
some spekboom (also known as “bacon tree” — it’s like bacon for kudus
and elephants) in your garden; it tastes great in salads and is packed
with vitamin C. But don’t expect it to capture more carbon than the
lavender bush next to it.
The real miracle, however, is the world we live in. Every habitat has
its own spekboom (or agave, or … ). Environmentalists are (rightly) up
in arms about the rampant deforestation in the Brazilian Amazon, but
Jair Bolsonaro is by no means the first leader to preside over
ecological genocide. Even the green and pleasant land that is Britain
was once a rainforest nation, columnist George Monbiot recently pointed out in The Guardian. With a little bit of ingenuity (and a lot of hard work), we can all do our bit at rewilding.
Here’s looking at you, industrialized nations.
