Camu Camu: A Little Fruit that Packs a Big Punch

By Eleanor Fausold

Sometimes the best things come in small packages. Camu camu (Myrciaria dubia) is a tiny fruit native to the Amazon region of South America that is rising in popularity, as both an element in local treats and a main component in dietary supplements. Although its high level of acidity once made it unpopular for consumption, the fruit is now valued for its exceptionally high vitamin C content and is, consequently, growing in demand in health-food stores around the world.

Also known as camocamo in Peru and cacari in Brazil, among other names, the camu camu tree can grow up to 40 feet high. The species thrives in swamps along rivers and lakes such as the Rio Mazán near Iquitos, Peru, and in Amazonian Brazil and Venezuela. The base of the camu camu’s trunk is frequently underwater, and the tree’s lower branches are often submerged for long periods during the rainy season.

Despite its frequent submersion, the camu camu tree produces fragrant flowers with tiny white petals and tiny fruits that turn from yellow to a maroon or purple-black color as they ripen. In the right growing conditions, a single tree can produce as many as 1,000 fruits per year, which are harvested by boat.

Known for its extremely high vitamin C content (half-ripe fruits have been found to contain 1,950 to 2,700 milligrams per 100 grams of edible fruit, an amount greater than that found in 50 oranges), the camu camu fruit has a very acidic taste. In fact, until fairly recently, the fruit was used almost exclusively as fish bait and the tree, when dead, was used as a source of firewood.



Five Rainforest Ecosystem Services that Nourish People and the Planet

From wetlands to coral reefs, the Earth’s diverse ecosystems support and regulate many of the planet’s most critical natural processes. They also contribute important cultural, social, and economic benefits to human communities. These contributions, known more broadly as “ecosystem services,” are estimated to be worth trillions of dollars per year.

The world’s rainforest ecosystem services—such as increased rainfall, soil stability, and a regulated climate—are integral to the successful production of food in many parts of the world. Rainforests in the Amazon and the Congo, for example, support rainfall in key, surrounding agricultural areas.

Today, Nourishing the Planet highlights five ecosystem services that rainforests provide to people and the planet:

1. Nutrient cycling and soil formation. According to the Rainforest Conservation Fund, many of the world’s tropical rainforests live “on the edge,” meaning that they receive very few nutrient inputs from the outside and must produce most nutrients themselves. When left intact, a rainforest acts as a closed-loop system, recycling the nutrients it has created; without tree cover, however, these nutrients would be lost and the forest would not survive.



Aguaje: the Amazon’s New Superfruit Secret Is Out

Researchers have stumbled upon yet another reason to save the Amazon rainforest. The aguaje fruit is just another nutrient-rich, pulpy gem with the potential to gain as much popularity as the now familiar acai berry or guarana extract. Local people living within the Peruvian Pacaya-Samiria National Reserve have cultivated this fruit, and a variety of others, as part of their culture. At the local market in the city of Iquitos, this small, scaly fruit generates US$4.6 million every year. But as global trends continue to rise in favor of unique, healthful food choices, the aguaje holds the capability to generate income for local growers and amp up Vitamin A intake for consumers around the world.

The aguaje fruit ripens on a palm tree, and when it is ready to eat, one must peel back the maroon scales before munching on the crisp yellow flesh inside. Tasters have compared the aguaje fruit to a carrot, although it boasts three times the amount of Vitamin A than this familiar orange root vegetable. Aguaje oil is also high in beta-carotene, oleic acid (also found in olive oil), and essential fatty acids that the human body cannot synthesize on its own. Amazingly, the oil also contains a naturally-occurring SPF that can filter ultraviolet rays and treat burns when applied topically.

University of Florida geographer and Professor Nigel Smith has devoted much of his career to research in the Amazon. In addition to its health benefits and pleasing taste, he believes that cultivation of the aguaje fruit by small farmers may play a part in the survival of a healthy rainforest ecosystem. Commercial farmers in the Amazon are often demonized for their large clear-cuts of monocropped staples such as coffee, soy, and rubber. However, small-scale farmers can actually play a positive role in maintaining a biologically diverse landscape that benefits both the natural ecosystem and the people living within it.

By encouraging a variety of edible plants to grow within the forest, these small-scale farmers are engaging in a form of agroforestry that uses the complex forest ecosystem as a model for highly productive food gardens. As one more element of a forest garden that flourishes in vertical layers of plant diversity, the aquaje provides another form of sustenance, should other crops fail due to pest damage, a disease outbreak, or severe weather.

Will the aguaje fruit become the next trend in exotic health food? It is already popular among local consumers, and value can be easily added by processing the fruit into juice, jam, or ice cream. If harvested sustainably, this humble tropical plant could boost the health of both the Amazon rainforest and a planet of 7 billion.

WWF Report– Soya and the Cerrado: Brazil’s forgotten jewel

By Philip Newell

According to a recent report released by WWF UK, the increased use of soy beans has had painful consequences for the Cerrado region of Brazil. The Cerrado is the unique savannah south of the Amazon Rainforest. This landscape, once covering a quarter of Brazil, holds an amazing 5 percent of all life on Earth. Since the prehistoric days when there was only one continent, this grassy expanse has harbored not only 11,000 flowering plants (nearly half are found only in the Cerrado) but also countless animal species, including the giant anteater and maned wolf. This rich history also imbues the land with cultural significance, as it has played a key role for over 10,000 years in the culture and religion of a variety of indigenous Brazilian societies.

Currently, however, the Cerrado is being converted into farmland for the express purpose of growing soybeans (soya). In only 15 years, production of soy has doubled, now covering an area almost the size of Egypt worldwide. In Brazil, there are 24.1 million hectares planted with soy, equivalent to the size of the United Kingdom. Such a prolific conversion has devastated the natural biodiversity of the region. A recent survey suggests that by 2008, almost half of the original vegetation cover had been lost, disappearing at a rate significantly greater than the Amazon rainforest. This also has significant consequences for climate change. According to WWF, in the six year period between 2002 and 2008, land-use change in the Cerrado released 275 million tons of CO2 per year-more than half the total emissions for the United Kingdom.

A whopping 80 percent of the soy grown worldwide is used for feeding cows, pigs, chickens and other livestock, according to the report. Current trends suggest that developing countries will continue to increase their meat consumption, until they match levels of developed countries. If soy remains one of the main components of livestock feed, then soy production will increase. Since most land planted with soy has already achieved maximum production levels (only the Indian region has room for improving yields), demand for land for soy planting will grow.
