Research: Higher beetle diversity in shade coffee, more pests in sun

Simplification of a coffee foliage-dwelling beetle community under low-shade management. C. E. Gordon, B. McGillb, G.Ibarra-NÁºÁ±ezc, R. Greenberg, and I. Perfecto. 2008. Basic and Applied Ecology, in press. doi:10.1016/j.baae.2008.04.004

This study looked at beetle abundance and diversity in coffee farms with high shade or low shade in the Soconusco region of the state of Chiapas in southern Mexico. Farms with low shade systems had lower or equal number of individual beetles, but fewer and more similar species than high shade systems. One beetle species, the dreaded coffee berry borer, la broca (Hypothenemus hampei), however, was far more abundant in the low shade farms (201 total on the low shade farms versus 23 on the high shade farms).

Another example of how shade may help reduce costs to the farmer, in this case, pest control.

Fight poverty: Quit drinking corporate coffee

If you are one of the 160 million coffee drinkers in the U.S., you can make a decisive, positive impact on poverty by refusing to buy coffee from, at least, Nestlè, JM Smucker, and Kraft Heinz. They sell over 30% of the retail volume of coffee in North America. Their brands include Folgers, Maxwell House, Nescafe, Gevalia, and others.

Here is how your grocery store coffee perpetuates poverty

  • Over 25 million people are directly dependent on coffee growing for a living, with another 100 million indirectly involved, including seasonal or temporary workers.
  • The majority of the coffee in the world is grown in 50 developing nations by producers that each farm less than 5 hectares of land [1].
  • Under good conditions, it costs a farmer around 30 cents (for the cheapest robusta in Vietnam) to 80 cents (for ordinary arabica from Central America; both are included in grocery store coffee) to produce a pound of coffee [2,3,4,5].
  • In 2007, even if farmers received the full market price for their coffee (and typically they do not), their profits amounted to 20 to 50 cents a pound [6,7].
  • Another way to look at it, is that only 5 to 10% of the retail price of a pound of coffee goes to the farmer [8,9,10], and the average retail price for a pound of ground coffee is well under $4.00 a pound.
  • Remember, this is a crop grown on a small plot of land harvested once a year that is probably the main source of income for an entire family.

The big multinational coffee companies perpetuate low coffee prices. Under the free market system, these four main buyers pit 25 million sellers against each other, creating a race to the bottom. They have funded and encouraged the expansion of the low-cost, low quality robusta coffee, and have spent millions of dollars developing technologies to make this bitter variety palatable. They use increasing amounts of this coffee in grocery store blends, further fueling deforestation and dragging down prices. A Wall Street journal article quoted officials from both Nestlè and Kraft as saying that they believe increasing consumer demand for coffee is the best way to help farmers, rather than paying above-market prices for their beans.

This situation is beginning to worsen, as production costs for coffee farmers around the world are rising due to the skyrocketing costs of petroleum-based fertilizers, and the global credit crunch.

The International Coffee Organization notes that low bean prices fueling corporate profits cause “entire rural communities to disappear…forcing desperate peasants into everything from crime and illicit crops to illegal migration.” [3]

Why should you care about the incomes of coffee farmers?

When coffee ceases to be profitable, the coffee fields — which for a large number of small holders are a mix of coffee, food and timber trees, and native shade trees — are cleared. They may be replaced with barren cattle pasture, subsistence crops, or some other crop less eco-friendly than coffee.

There is a direct link between environmental degradation and poverty. There is also a substantial overlap between coffee growing areas and biodiversity hotspots. Deforestation in these areas has severe consequences for loss of biodiversity. Tropical forests, even agroforestry systems, sequester many tons of carbon and help buffer against climate change.

Often the only alternative cash crop is drugs. In Latin America, the crop of choice is coca, the raw material for cocaine.

Efforts to eradicate coca in the coffee-growing nations of Colombia, Peru, and Bolivia are funded by your tax dollar, to the tune of $5 billion so far. This effort has been unsuccessful, and coca production continues to rise. All of the cocaine destined for the U.S. is grown in the Andes, with 90% from these three countries. The cost of drug abuse to society impacts every single one of us.

As coffee prices fall, such as during the coffee crisis in the 1990s, some farmers simply abandoned their land. Some were forced to sell their assets, such as cattle. They took their children out of school. Child malnutrition climbed. Communities wrenched apart by the coffee crisis have not fully recovered. Many farmers that stayed in coffee continue to be in debt.

This was and is a humanitarian crisis. Thousands of impoverished coffee farmers made their way north, with many crossing the border into the U.S. to seek employment.

Can switching the coffee I drink really help?

The U.S. is one of the world’s largest coffee consumers. We can make a difference. Quit supporting the poverty and environmental destruction that cheap coffee from these large multinationals perpetuates.

Good coffee for which a fair price is paid is not too expensive for most Americans. In fact, 45% of Folgers and Maxwell House purchasers have incomes greater than $50,000 a year. Even coffee that costs $15 a pound works out to well under a dollar a cup, tastes great, helps preserve biodiversity, and provides a decent living for coffee farmers.

Research: Shade coffee = more pollinators = higher fruit set

Pollinator diversity increases fruit production in Mexican coffee plantations: The importance of rustic management systems. C. H. Vergara and E. I. Badano. 2009. Agriculture, Ecosystems & Environment 129: 117-123.

Although arabica coffee is self-pollinating, it can benefit from the activity of insect pollinators. This study looked at pollinators in coffee farms in Veracruz, Mexico that used various types of shade management. Rustic shade had the highest number of pollinating species (12), closely followed by polyculture shade (11). Sun and specialized shade (shade monoculture) had the least number of species (5 and 4).  The more shaded farms also had significantly higher fruit set, which was positively related to the diversity of pollinators.

This has important economic implications. Coffee farmers need to see the economic advantages to any change in their management practices. It is often believed that shade results in lower yields. In this case, we see that increased shade (especially diversity in the shade management) encourages a wider diversity of pollinating insects, which in turn leads to higher fruit set in the coffee and thus higher yields.

Book review: God in a Cup, The Obsessive Quest for the Perfect Coffee

Journalist Michaele Weissman has put together a great overview of the world of specialty coffee in God in a Cup. She traveled around the world with coffee buyers and explored the contrast between mass-produced, commodity coffee and artisan-focused, quality-oriented specialty coffee.

This book isn’t really about searching for great tasting coffee, but uses that pursuit to frame the genesis and impact of specialty coffee for consumers and especially producers. While not strictly about coffee sustainability, it nonetheless brings alive many of the points that I strive to make here at Coffee & Conservation on the topic and the crucial role specialty coffee roasters make in this arena — and in turn how consumers can support it. As such, it lays the foundation for much of what I discuss here.

Weissman preserves her artfully-paced narrative by placing the in-depth background information at the back of the book or in boxes, but still provides enough detail in the main text to clearly explain to readers unfamiliar with the coffee trade and the stakes involved.

She does a great job of highlighting the passion — and activism — of the pioneers in this industry. Much of the focus is on her travels and interviews with three of them: Counter Culture’s Peter Giuliano, Intelligentsia’s Geoff Watts, and Stumptown’s Duane Sorenson, but many others are mentioned. This personal touch lends authenticity. It also keeps readers connected, as following these coffee buyers provides an opportunity to really understand the complexities involved in producing this crop and bringing it to market. Most revealing for me were the discussions about Fair Trade, and in particular the examination of the cooperative system. The example of the troubles Watts has had with poorly run organizations helps to illustrate that cooperatives (which are the only producers allowed to be certified Fair Trade) are not always the best way to protect farmers.

I approached this book with a little trepidation, as I have read way too many articles about coffee that were superficial, not factual, lacked a fresh approach, or were just examples of lazy reporting. This was none of these. If you are at all interested in coffee (which you must be if you have read this far), I highly recommend this book. Further, get a couple extra copies for your coffee-loving friends, people you would like to convert to specialty coffee, or those in your life that don’t really “get it.” God in a Cup will make a great gift this holiday season.

To get a sense of what this book covers and Weissman’s take on it, read this interview with her at Salon. She also maintains a blog which explores her ongoing coffee experiences. Then go pick up a copy of her book!
