After Acai, What Is Amazon's Next "Cinderella Fruit"?

Whether it's the aguaje or a tangy-sweet relative of the cacao called the cupuaçu or macambo seeds, a crunchy new alternative to peanuts, Smith has studied them all with an eye toward promoting conservation, boosting sustainable farming in a threatened region, and supporting local residents' livelihoods.

The Land Squeeze

The past three decades have seen unprecedented human migration into the Pacaya- Samiria reserve, part of an area Smith calls the "epicenter of wild-fruit consumption in the Amazon."

Other pressures, like hunting, logging, and unsustainable fishing, are on the rise as well. As these pressures grow, Smith believes small farmers hold a key to managing and protecting the region.

With support from the National Geographic Society's Committee for Research and Exploration, the MacArthur Foundation and the Moore Foundation, he and his team, including Peruvian botanist Rodolfo Vazquez, spent six months in Pacaya-Samiria over several years documenting 148 different fruit species. (The National Geographic Society owns National Geographic News.)

They studied how small landowners in a dozen communities use and depend on these fruits, many of which large-scale farmers ignore.

"I'm interested in landscapes where individual landowners are in control," Smith says. "I think that's the great frontier for Amazon conservation."

Over the years, he notes, small-scale farmers have helped shape the forests where they pick and cultivate fruits by "rearranging the biological furniture" in ways that encourage biodiversity.

These farmers "have retained a biologically diverse landscape that benefits not only wildlife but also their own livelihoods," Smith adds.

Crop Insurance

One way Pacaya-Samiria residents have accomplished that is by domesticating potentially valuable wild fruit species, including macambo seeds and vitamin A-rich sapote.

They often plant and grow several at once in diverse forested plots, a strategy known as agroforestry. The combination of crops, both annual and perennial, helps the farmers avert risk.

Should one crop succumb to inclement weather, disease, or a pest outbreak, the other crops would likely survive, ensuring that the farmers have both food and income.

But Amazon experts agree that more needs to be done.

So far the Peruvian Amazon has been spared much of the deforestation caused by the timber trade and cattle ranching in Brazil, yet Smith warns that the "floodplains are going to come under increasing development pressure in the next few decades."

Overharvesting of fruits would threaten trees. And logging is of enormous concern throughout the entire Amazon region, says Douglas C. Daly, an expert on Amazonian botany at the New York Botanical Garden.

That's one reason Smith's work is important. "If we can educate people about the wealth of diversity, as opposed to just the wealth of timber, we can change things," Daly says.

Finding the Next "Cinderella Fruit"

This is where native fruits may come in. Some of the Amazon's little-known produce has the flavor, the nutrition, or the novelty to tempt commercial producers abroad, and Smith hopes that growing international awareness of the dietary importance of fruit could help create a new hit.

His knowledge is helping at least one entrepreneur take steps to market bottled water flavored with Amazon fruits. Jeff Moats, CEO of the Equa Water Corporation in Naples, Florida, plans to begin building a factory next year in Brazil's Amazon region to process fruits local residents can grow sustainably within forests.

But competition from carbonated soft drinks, a $40-billion industry in the U.S. alone, presents a formidable obstacle to anyone wanting to sell Amazon fruit juices. Entrepreneurs "cannot match the marketing muscle and advertising dollars of the major soda producers," Smith says.

Beyond this, fruit supplies can be erratic, and the Amazon region is still struggling with the basic issues of hygiene, infrastructure, and quality control.

So what are the chances you'll someday see vitamin-rich aguaje in your supermarket's produce section alongside carrots, tomatoes, and apples?

It's hard to predict, but Smith is encouraged by the example of the once obscure açaí, which was enjoyed in Brazil long before becoming a hit in eco- and nutrition-savvy foreign markets.

He also notes the success in Japan of the camu camu, a sour maroon berry with 30 times the vitamin C of oranges. The aguaje might become what he calls a "Cinderella fruit" since it fits some of the criteria that have made these other two fruits successful: It's already popular and abundant locally, easily incorporated into products like juice, and relatively simple to transport.

"The production of fruit is vital to the life of an Amazonian person and is of enormous nutritional importance," emphasizes Walter Wust, a Peruvian forester and environmental journalist who helped Smith document the Pacaya-Samiria fruits.

If Smith has his way, more of that bounty will someday nourish the rest of the world as well.
