Our Dwindling Food Variety

Our Dwindling Food Variety | Social Studies 7 Resources | Scoop.it

"As we've come to depend on a handful of commercial varieties of fruits and vegetables, thousands of heirloom varieties have disappeared. It's hard to know exactly how many have been lost over the past century, but a study conducted in 1983 by the Rural Advancement Foundation International gave a clue to the scope of the problem. It compared USDA listings of seed varieties sold by commercial U.S. seed houses in 1903 with those in the U.S. National Seed Storage Laboratory in 1983. The survey, which included 66 crops, found that about 93 percent of the varieties had gone extinct. More up-to-date studies are needed." 

 

To show the other side of the issue, include this minor, yet crucial part of the article: "A 30-year-old plant pathologist named Norman Borlaug traveled to Mexico in 1944 to help fight a stem rust epidemic that had caused widespread famine. Crossing different wheat varieties from all over the world, he arrived at a rust-resistant, high-yield hybrid that helped India and Pakistan nearly double their wheat production—and saved a billion people from starvation. This so-called green revolution helped introduce modern industrialized agriculture to the developing world."

This article raises multiple questions like, what has happened to all these different strains of vegetables? Why have the ones that are still around survived? Was this a process of natural selection? It would certainly be interesting to research this and uncover the reasons.

Produce Calendars: Understanding Agriculture

Produce Calendars: Understanding Agriculture | Social Studies 7 Resources | Scoop.it

These three charts (Fruit, Vegetable and Herbs) are an excellent reasource for teaching about agriculture and food systems.  Many cultural festivals and  traditions revolve around the seasonal availability of crops and many modern eating trends often call for a return eating foods within their season.

Justin McCullough's curator insight, December 12, 2013 10:15 AM

I feel that when you do consume foods within their season of growth it tastes better. I like to believe that because they are in season, it is cheaper to buy them because they are in abundance but it don't think that is the case. Although there is the push to try to eat the foods within their seasons, it is probably not likely to happen since we live in a global economy, that urges food to be made regardless of what season they are best grown in.

Sometimes whe teach human geography as though it is not connected to physical geography.  The geographical distribution patterns of agriculture are some of the most highly correlated human activities to the physical environment.  This one, dairy productivity, changes greatly based on temperatures, humidity and latitude.
