Seaweed gains ground as a pillar of food security in South America

ENGLISH Seaweed, a nutrient-rich foodstuff that was a regular part of the diet of several South American indigenous peoples, is emerging as a new pillar of food security in Latin America and is providing a livelihood for thousands of people in the region’s coastal areas.

“I have been harvesting seaweed since I was five years old, and now I am 50. The person who always buys all my produce says it is used to make creams and plastics,” Zulema Muñoz, a seaweed collector in the small coastal town of Matanzas on the Pacific ocean 160 km south of Santiago.

Seaweeds have been used as human food ever since ancient times, especially in China, the Korean peninsula and Japan.

“Seaweeds must definitely be cultivated because we cannot simply collect the wild algae populations. Experience shows that over-exploitation is a widespread problem - not only for seaweed - for which we must find sustainable solutions” - Erasmo Macaya.

When people from these countries migrated to other regions of the world they took their food habits with them. This is why dishes based on fresh, dried and salted algae can be found in nearly every corner of the earth.

According to the Food and Agriculture Organization of the United Nations (FAO), some 25 million tonnes a year of seaweeds and other algae are gathered worldwide for use as food, cosmetic and fertiliser ingredients; they are also processed to make thickeners and additives for animal feeds.

FAO says that marine aquaculture products, particularly algae and molluscs, contribute to food security and the alleviation of poverty, since most producers work in small- or mediumsized fishing businesses.

In Latin America, hunger affects 34 million people out of the total regional population of 625 million, according to FAO’s statistics. Countries like Argentina, Brazil, Colombia, Cuba, Ecuador, Mexico, Peru and Venezuela have explored seaweed production for food.

In Chile, “studies carried out in Monte Verde (in the Los Lagos region, 800 km south of Santiago) showed that in one of the earliest human settlements in the Americas, people ate seaweed as part of their diet,” said Erasmo Macaya, principal researcher at the Algal Research Laboratory at Chile’s prestigious University of Concepción.

Marine algae “were a food source for the Lafkenche indigenous people, who used them (and still do) as part of their diet, particularly kelp (Durvillaea antarctica), known as ‘kollof,’ and ‘luche’ (Pryopia and Porphyra species),” he told IPS, speaking from the southern city of Concepción. (IPS)
