Valentine’s Day is celebrated across the United States on February 14, and is often marked by the gifting of flowers. But we rarely stop to consider how the global trade in flowers—which increases sharply ahead of both Valentine’s Day and Mother’s Day—connects us to the broader world.
The global trade in cut flowers is estimated to be worth $100 billion annually, with the United States alone accounting for about $13 billion. About 82 percent of all flowers sold in the United States are imported from abroad, with the majority of US-destined flowers arriving from Latin America. Europe, by contrast, tends to import the bulk of its cut flowers from Africa.
The sharp seasonal fluctuations in flower production presents challenges to customs and border officials responsible for inspecting imports. Concerns over pests and disease are the primary focus for their inspections.
Developing countries looking for a comparative advantage in the context of historical subsidies offered to food and cotton producers in the developed world have often transitioned to specialized crops like cut flowers, spices, or specialty coffees in an effort to carve a market niche where they can complete on a more equal playing field.
While the global flower trade has increased sharply over the past decade, concerns over the environmental impact of the practice are growing. A 2009 report by Flowerpetal.com noted that about 80 percent of the estimated 100 million roses sold for Valentine’s Day were produced abroad, generating an estimated 9,000 metric tons of carbon dioxide (CO2) emissions. A similar study by Cranfield University in 2007 found that a single rose imported from Kenya generated about 1.1 pounds of CO2. The same report noted, however, that imported flowers were far more carbon efficient than flowers raised in greenhouses in Europe, the production of which generated an estimated 6.4 pounds of CO2 per flower. In such a case, the higher CO2 emissions associated with transporting the flowers are offset by the more favorable growing environments abroad.
Then there’s the use of pesticides, herbicides and chemical fertilizers in the growing process, all of which raise potential questions about the ecological suitability of the cut flower trade.
What do you think? Should we be concerned about the ecological questions raised around the cut flower trade? How should we balance ecological concerns associated with climate change and chemical runoff against the clear need to secure economic development in the global south? What solutions might you envision to this tradeoff?
