Sorghum

Sorghum bicolor

A drought-tolerant grain originating in Africa (likely Sudan-Ethiopia region) ~6,000-8,000 years ago; the world's fifth-most-produced cereal grain. Foundational food across much of Africa, India, and increasingly the U.S. (where most sorghum is currently fed to livestock or used for ethanol; food consumption is growing as gluten-free demand expands). C4 photosynthesis makes sorghum exceptionally efficient in heat and drought. Tens of thousands of varieties exist globally; sorghum sweet-stalks (sorghum syrup) produce a different food product than grain sorghum. Likely to expand significantly as climate change makes drought-tolerant grains more valuable.

Description and origin

Tall grass — 3-15 ft tall; large open seed panicle at top
Origin — Africa, likely the Sudan-Ethiopia region; domesticated 6,000-8,000 years ago
Spread — to India and China by ~3000 BCE; later to Mediterranean, Americas
Multiple types — grain sorghums, sweet sorghums (for syrup), broomcorn sorghum (for brooms), forage sorghums (for hay/silage)

C4 photosynthesis

Sorghum uses C4 photosynthesis — like corn and [[sugarcane|sugarcane]], more efficient than C3 (wheat, rice) at:

High temperatures — operates well at 90+°F where C3 plants stress
Low water — substantially more drought-tolerant than wheat or rice
Low atmospheric CO₂ — less affected by current atmospheric levels
Hot dry sun — thrives where many crops fail

These traits make sorghum increasingly important for climate-resilient agriculture.

Where it’s the staple

Sub-Saharan Africa — sorghum is foundational across [[sahel|the Sahel]], Horn of Africa, southern Africa; staple grain for hundreds of millions
India — jowar; significant calorie source, particularly in Maharashtra, Karnataka, Andhra Pradesh; “millet revival” includes sorghum
China — historically significant; declining as wheat and rice dominate
United States — primarily livestock feed and ethanol; food market growing in [[gluten-free|gluten-free]] space
Australia — substantial commercial production

Forms of food

Whole grain — boiled like rice; typical Indian and African preparation
Flour — used for flatbreads, porridges, fermented foods
Injera-style fermented flatbreads — common across Africa
Bhakri/jowar roti — Indian unleavened flatbreads
Pancakes and pancake-style — across many traditions
Beer — sorghum beer is widespread across Africa; [[gluten-free|gluten-free]]
Popped sorghum — like popcorn, smaller kernels
Sweet sorghum syrup — produced from sweet-sorghum stalks; analogous to [[sugarcane|sugarcane]] syrup or molasses

Nutritional profile

Sorghum (per 100g whole grain):

Protein — 10-12%
Fiber — 6 g
Iron, magnesium, phosphorus, B vitamins
Resistant starch (high)
[[gluten-free|Gluten-free]]
Polyphenols — particularly in red/brown sorghum varieties; antioxidant activity

Why it matters

Sorghum is among the most-likely climate-resilient grains. As climate change intensifies drought and heat in many growing regions, sorghum’s adaptive properties become increasingly valuable. Combined with substantial Indigenous cultural significance and current cultivation across critical food-insecurity regions, sorghum is foundational to climate-adapted food systems.
