HOW COULD ROOTCROPS POSSIBLY SAVE US FROM HUNGER AND EVEN FAMINE?

HOW COULD ROOTCROPS POSSIBLY SAVE US FROM HUNGER AND EVEN FAMINE?

We often think of rice, corn, and wheat as the pillars of human survival. In countries like the Philippines, rice is not just food—it is identity. But history, science, and even common sense are quietly telling us something uncomfortable: depending too much on a single staple is a dangerous gamble.

Consider a story from 1770. When Captain James Cook’s ship, the HMS Endeavour, struck the Great Barrier Reef, his crew was stranded for weeks along the Australian coast. Their survival did not depend on imported seeds or stored grain. Instead, it hinged on what nature had already prepared for them—root crops like wild taro and yams. These humble plants, growing quietly in swampy ground, provided the starch, nutrients, and resilience that kept the crew alive long enough to repair their ship.

That story is not just history. It is a warning—and perhaps a blueprint.

Root crops—cassava, sweet potato, taro, yam, even lesser-known ones like yacon and konjac—are often called “famine crops” for good reason. They are not glamorous, but they are reliable. While rice needs controlled irrigation and is vulnerable to floods, droughts, and typhoons, root crops grow underground, protected from the very disasters that destroy grain fields.

Let us ask a difficult question: what happens if rice becomes scarce or too expensive? We have already seen how fuel prices can spiral beyond the reach of ordinary people. Why should food be any different? Climate change, supply disruptions, and rising input costs could easily push rice into the same category—available, but unaffordable.

If that happens, will we be ready?

Root crops offer several quiet advantages that we have long ignored. First, they produce more calories per hectare in many cases than grains. Second, they thrive in marginal lands—rocky, sloping, or drought-prone areas where rice simply cannot grow. Third, they act as a “living granary.” Unlike grains that must be harvested, stored, and protected, many root crops can remain underground for months, even years, until needed. That alone could reduce post-harvest losses, which account for a significant portion of food waste in developing countries.

More importantly, they are not just fillers. Orange-fleshed sweet potatoes are rich in Vitamin A. Cassava provides energy where little else will grow. Taro contains minerals and even modest protein. In other words, they can fight not only hunger but also “hidden hunger”—micronutrient deficiencies that silently weaken populations.

What fascinates me most is their versatility. These are not just boiled substitutes for rice. They can be processed into flour for bread and noodles. Cassava flour is already widely used as a gluten-free alternative. Even konjac can be transformed into rice-like products that cook and feel similar to what many families are used to. Imagine that—a backup staple that looks and behaves like rice, but grows under far harsher conditions.

So why are we not investing more in this?

Perhaps the answer lies in habit. We are culturally attached to rice. I understand that. I share that sentiment. But survival should never depend on habit alone.

My suggestion is simple: diversify our staples before a crisis forces us to. Governments should promote root crop farming, support processing technologies, and integrate these crops into school feeding programs and public awareness campaigns. Households, on the other hand, can begin small—experimenting with cassava bread, sweet potato noodles, or even growing root crops in pots.

Because in the end, food security is not just about having enough food. It is about having options.

History has already shown us that in times of crisis, it is not always the most popular crops that save lives—but the most resilient ones. The question now is: will we wait for another disaster to prove it again?
