Pesticide resistance in coffee berry borers

The coffee berry borer, or broca (Hypothenemus hampei) is the most serious insect pest of coffee. Originally native to Africa, it has been unintentionally introduced to just about every coffee-producing nation in the world. Female beetles lay 30-50 eggs inside a coffee cherry, which hatch and develop inside. Thus, they damage the cherry and cause defects or the cherry drops off the tree and causes a loss. Economic impact can be substantial.

Nearly the entire life cycle of this very tiny beetle takes place inside the coffee ripening coffee cherry. For that reason, pesticides can be largely ineffective against it. Nonetheless, the neurotoxic organochlorine insecticide endosulfan is widely used in coffee farms to try to fight the borers. Not only is this not very effective, it is bad for the environment, and the life history of these beetles enables them to rapidly develop resistance to endosulfan.

The dangers of endosulfan
Endosulfan is considered highly toxic, and it has been banned in many countries, including the entire European Union. In the U.S., the Fish and Wildlife Service recommended it be banned in 2002, and a number of science and environmental groups continue to pressure the EPA to ban this pesticide (updates on U.S. ban and worldwide phase-out).

Many cases of poisoning of coffee workers by endosulfan in Colombia resulted in a ban in that country in 2001. Endosulfan, to be even marginally effective, requires rather intensive spraying because of the relatively low probability of making contact with borer beetles that are actually outside of a coffee cherry and the high concentration needed for vapor to cause mortality of any beetles that have penetrated the skin of a coffee cherry.

Even when pesticides are banned in developed nations, they may continue to be used for many years in developing countries, such as coffee growing nations. Endosulfan is toxic to insects and animals (including humans) and can persist in the environment. Pesticides are frequently applied in these countries without proper safety precautions. At a recent coffee conference, Ernest Carmen of Costa Rica’s Cafe Cristina said that endosulfan is regulated and considered toxic in Costa Rica, but that it is freely available and indiscriminately applied, even though it is not that effective against broca.

What makes coffee berry borers so able to develop resistance to endosulfan?
Coffee berry borers have an interesting life history that enables them to readily develop pesticide resistance. Most borers are females (13 to each male). All males are flightless, and mate with their sisters because they never leave the cherry in which they are born. This results in genetic inbreeding. When the mutation for endosulfan resistance pops up, it can rapidly spread through a population because of this inbreeding [1,2]. This has already occurred on the island of New Caledonia [3], and would be devastating if (or when) it happens in a mainland coffee producing region.

Alternate solution: promote shade coffee and habitat preservation to control pests!
This study found ground-foraging ants are more common and eat more coffee berry borers in fallen coffee cherries in shade coffee than on sun coffee farms. This one found that coffee farms that had little shade also had fewer beetle species — except they had a much higher abundance of coffee berry borers. And this study showed that at coffee farms which were close to natural habitat patches, migratory birds preyed upon coffee berry borers, enough to bestow a healthy economic benefit to farmers.

New biocontrol methods, especially the role of natural predators associated with shade, is an area that is and will continue to draw more research attention.

Roast Magazine’s 2008 Roaster of the Year

I’m in the habit of mentioning Roast Magazine‘s annual Roaster of the Year awards, and I’m a bit tardy in posting the 2008 results.

This year, the macro Roaster of the Year goes to Topeka’s PT’s Coffee Company. Over 95% of the 225,000 pounds PT’s roasted last year came from small lots. Thus PT’s is a great source of very special single origin coffees, many of them sourced under their direct trade model, which includes healthy environmental practices.

It’s been awhile since I have had any of PT’s coffees, so in honor of their honor, I placed an order. I was especially keen to try their Finca Kilimanjaro, from one of Aida Batlle’s El Salvador farms. I’m a big fan of her coffee; you can read our reviews of several of her coffees from Counter Culture here. Aida received organic certification on all three of her farms earlier this year (Mauritania, Kilimanjaro, Los Alpes). The Finca Kilimanjaro is grown at 1650 m on the slopes of the Santa Ana volcano under diverse shade. There are 30 ha in coffee.

This coffee recently scored 95 from Coffee Review. PT’s has already sold out of this coffee, so I won’t do a full review. Let me just say this coffee deserved that 95, and is another stellar example of Aida’s commitment to exceptional sustainable coffee. She grows the Kenyan SL28 variety at Finca Kilimanjaro, and it’s wine-like acidity shines through. This coffee is juicy, very floral — it reminded me a lot of the famous Hacienda La Esmeralda — with a truly room-filling aroma. It was easily one of best coffees I’ve had all year, and had we been doing a review, I would have given it 4.25 motmots.

Moving on, Roast’s micro Roaster of the Year is Coffee Klatch of California, whose coffees are frequently high scorers at Coffee Review. Even roasting less than 100,000 pounds a year and with only four employees, owner Mike Perry still makes several trips to origin a year. He also pursues a direct trade model, and in fact often travels and buys lots with PT’s Jeff Taylor. About a third of Coffee Klatch’s coffees are direct trade, but they also carry Fair Trade selections, as well as a variety of organic coffees. They note that a few of their organics such as the Peru and Mexico are “also shade grown and therefore considered ‘Bird Friendly.'” However, there is no mention of the Smithsonian Migratory Bird Center (the certifier that trademarks “Bird Friendly” coffee) and not enough information in the item descriptions for me to figure out if these are SMBC-certified farms.

Here are my posts on the 2005, 2006, and 2007 winners.

Research: Shade coffee provides additional income besides the coffee crop

Agricultural intensification within agroforestry: the case of coffee and wood products. 2008. Rice, R. A. Agriculture, Ecosystems, and Environment 128:212-218. doi:10.1016/j.agee.2008.06.007

Robert Rice, of the Smithsonian Migratory Bird Center, surveyed 338 owners of coffee farmers in Peru and Guatemala to determine what portion of total income from shaded coffee farms was attributable to non-coffee products derived from the farm. These were smallholders (under 3 ha of coffee; average total farm area was 10 ha in Peru and 6.2 ha in Guatemala). The value of the non-coffee products was based on local market prices, and included the value of products both used/consumed by the farmers, and exchanged or sold.

A fifth to a third of the total value came from non-coffee products. Fruit and fuelwood were the two biggest non-coffee income producers in both countries; lumber for construction materials was also important. Because yields and prices are higher for coffee in Guatemala, the percentage of income derived from non-coffee products was lower there, just under 19%. In Peru, it was 28%.

This is one of the first studies to quantify the “shadow economy” in shade coffee agrosystems that exists alongside of the economics of the coffee production itself. Diversification is particularly important for farmers producing a crop such as coffee, which is so sensitive to global price flucuations. Hopefully, we are also working toward proper appraisal of the value of carbon sequestration and biodiversity preservation in shade coffee systems. When mechanisms are in place to compensate farmers for these less-tangible assets, it should provide further motivation for farmers to foster diverse shade in their coffee holdings.

Discontent with certifications

In my post about the Coffee Conference, I noted that one of the most interesting things I came away with was the general displeasure many participants had with coffee certifications. Both Rainforest Alliance and TransFair USA (the Fair Trade certifiying organization in the US) had representatives at the conference. RA’s Bethany Koch (Client Relations Manager) and TransFair’s Kim Moore (Director of Business Development, Coffee and Beverages) both gave presentations that provided current statistics on the amount of coffee certified by each agency, and their various partners.

Participants had several bones of contention.

  • Conflict between the mission of the organizations and their corporate partners. Specifically mentioned were RA’s partnership with Chiquita bananas and Kraft, and both organizations with Walmart. These companies have had very checkered pasts (or presents) and their histories and behavior struck people as highly at odds with the principles behind these certifications. Several people were strident about the hypocrisy of purporting to help small farmers considering Chiquita’s role in destroying the Caribbean banana farming industry. I thought one questioner’s hair was going to catch fire. Likewise, Walmart has faced a lot of criticism about unfair treatment of it’s own workers. Moore’s response regarding Walmart was that Fair Trade is concerned with the producers, not the retailers. Further, he said that all big companies had some dark holes in their pasts, and in essence that TransFair/Fair Trade wanted to look forward and not back. Likewise, people were disturbed by the fact that large roasters such as Kraft can use only 30% Rainforest Alliance certified beans and still put the RA seal on the bag (albeit with a disclaimer). Koch replied with the answer that I have received before from RA. First, that there isn’t enough supply to satisfy the huge demand of  large roasters. However, minutes prior she showed a graph indicating supply was larger than demand, a gap RA strove to maintain so that there would always be enough certified beans. I can only surmise that there isn’t enough supply that matches Kraft’s “flavor” profile. And second, although the volume of certified beans purchased by Kraft (20,000 metric tons in 2007) is a small fraction of their total purchases, RA believes that this makes a huge difference on the ground, and that changing the way a large and influential coffee company does business is a big step in the right direction. This “30% rule” is worthy of a post all of its own. Suffice to say that overall, people did not seem satisfied with these responses.
  • Fair Trade prices are too low. The Fair Trade floor price was recently raised to a modest $1.25/lb (there is also a $0.10 social premium that does not necessarily go to the farmer), only $0.11 higher than when it was established in 1988. Producers at the conference noted several times that it was not adequate to compensate for the rising cost of production. This same conclusion was drawn by Daniel Jaffee in his excellent book Brewing Justice: Fair Trade Coffee, Sustainability, and Survival.
  • Exclusionary policies of Fair Trade. Fair Trade certification is only available to cooperatives, not to individual small farmers or larger plantations (and therefore does not protect temporary workers at these locations). Further, Moore revealed that even many cooperatives do not qualify for Fair Trade certification. A representative of the PEARL project questioned the wisdom of small cooperatives in Rwanda participating in Fair Trade since the cost of the certification itself was a large percentage of revenues for these producers which still had low outputs. Moore’s answer was direct and honest, but made more than a few people squirm. He noted that co-ops needed to be commercially viable entities in order to qualify for certification. He said that Fair Trade is not a beginning intervention point and “Fair Trade is not for the very most in-need farmers.”

Geoff Watts pointed out that Fair Trade uses promotional language that “glorifies” cooperatives and implies that private sector efforts are evil. I’ll add that this applies to other certifications, which often urge buyers to only buy certified coffee (whatever seal is being promoted) as the only ethical choice. Watts said this leads consumers who want to do the right thing away from choices that might do the most good (e.g., Direct Trade initiatives). Indeed, in private conversations I had with some of the small retail roasters in attendance, all told me that they have had customers in their shops who demand coffee with a Fair Trade seal and didn’t even want to hear about directly-sourced coffees from farms that had been paid more than the Fair Trade price. As Jaffee asks in his book,

“What good will it do to have Nestlé displaying the fair-trade seal on a tiny portion of its coffee if the company ultimately succeeds in confusing consumers and undermining their confidence in the integrity of fair trade overall”?

As evidenced by opinions expressed at this conference, the integrity of these seals has already been diluted or compromised. Their success depends not only on the support of consumers, but also roasters and retailers. TransFair and Rainforest Alliance need to examine adopting some sort of tiered certification system that differentiates between products that are truly 100% certified, and those that are part of a limited effort. Brands which use only small portions of certified beans should be required to increase by a set percent over a specified time period, and all these actions should be transparent to the public.

Further, I believe that large corporations (the big roasters) should bear the burden of the costs of certifying the producers. These costs — initially $2000 to $4000 plus regular inspections — prevent many producers from ever getting certified in the first place, locking them out of these markets. The multinationals can well afford to cover these expenses. This will also have the added benefit of acting as an investment by these corporations in their suppliers, providing, one hopes, some long-term stability. I’d also like to see some sort of additional fee paid by these large companies, for as long as their certified supply remains under a particular level, that would help subsidize the fees of other farmers.

Socially and environmentally responsible seals have worthy standards and great missions, but their success depends on goodwill and trust. What I found intriguing was that this was a left-leaning crowd, the type that typically supports, and even helped found, these certification movements. It’s a shame to see this trust eroding.

Coffee review: Counter Culture Coffee Finca Nueva Armenia

Plainspoken Coffee. A Coffee Review for Ordinary People by Ordinary People, #39.

We did a quick take on Counter Culture’s Finca Nueva Armenia a couple of years ago, as it was used in their Sanctuary shade-grown coffee line. We liked it then, we like it now.

This certified organic selection from the Huehuetenango region in Guatemala is now one of Counter Culture Direct Trade Certified coffees. FNA was founded in the late 1800s. The current owners, the Recinos family, have had it since the 1940s and are now in the fourth generation of coffee farming. The farm went organic in the 1990s — one of the first organic farms in the country.

Coffee grows under multi-tiered shade with 50 species of shade trees recorded on the farm. The farm was very recently qualified for Smithsonian Bird-Friendly status. This is significant, as the farm is quite large — 113 ha. FNA grows mostly bourbon and typica varieties, at 1500 to 1833 m (click on this map for a satellite image).

As a family-owned farm, Finca Neuva Armenia doesn’t qualify for Fair Trade certification, which only covers small farmers that are part of a cooperative. But the Recinos family pays their workers 30% more than surrounding farms during the harvest, including even better rates at the end of the harvest when the per-person picking yield drops, in order to encourage picking for quality as opposed to quantity. And the Counter Culture Direct Trade program pays farmers well above Fair Trade prices.

On the package, this is described as a “classic breakfast coffee. It is certainly that — very well-balanced, light-bodied, the last drop tasting as good as the first without turning bitter in the cup. It was gently sweet, with milk chocolate tones and a short finish. But it is what I like to call a “classic ++”, as there were just these hints of other flavors that made it stand out from the typical classic Central American profile. For several tasters, there was an apple or apricot aspect. One person thought it was “spicy”, but another put his finger tongue on it with “cinnamon”. For me there was also a spicy/savory aroma and flavor, especially when the coffee was prepared as a pour-over or French press, that I really liked. I found myself chasing after that taste in sip after sip. I was never able to describe it more specifically, but sure enjoyed trying! It averaged out at 3.75 motmots; my score is just over 4 motmots.

If you are looking for a really great quality, super-tasting, affordable coffee that is farmed under the most stringent environmental criteriathis is it!

The Coffee Conference

My husband and I attended the Coffee Conference at Miami University in Oxford, OH. I’ve now been to meetings that covered coffee from every angle: ecological (ornithological conferences), trade (SCAA annual meeting) and now the academic and scholarly. This event had a wide range of speakers on a variety of topics. The audience was also varied. As far as I could tell, there were perhaps 75 registered participants, including small roasters, academics from many disciplines (history, economics, literature), and representatives from producing countries and NGOs. Many Miami U. students also attended.

I will be following up with a more detailed post on what for me was the most interesting message I came away with: the fairly uniform negative attitudes toward certification agencies, ranging from distrust to disgust. Right now, I’ll just try to burnish my own legitimacy by doing some name dropping and showing you photos of famous coffee people.

Geoff Watts, left, of Intelligentsia gave a talk about Direct Trade relationships. In his discussion, Geoff noted that environmental sustainability has to be part of what is fostered and encouraged in direct relationships with farmers. He said that although a farm might be producing great coffee, if the land isn’t taken care of then it cannot continue to produce the same quality coffee over the years. Ecological integrity is part of the equation.

Geoff also offered a lot of the kind of insightful commentary on other talks, especially regarding Fair Trade, that only someone who has been intimately involved with producers can provide.

Ken Davids gave a great talk on interpreting the iconography and images of coffee through time. He grouped them by theme, such as the 1950s “Good Cuppa Joe” — coffee as every man’s luxury — or the “Safari in a Cup” adventure at exotic origins symbolism of the early specialty coffee movement. If  Ken hadn’t noted that his early background was as a novelist and college writing teacher, I would have guessed it by his presentation. It was creative, clever, and reminded me of the kind of deep interpretation of literature that I recall from my undergrad days. Very enjoyable — and I can’t imagine seeing a talk like this at any other kind of coffee conference.

At dinner, George Howell (center in front of laptop) showed off his new Extract MoJo software to Geoff Watts of Intelligentsia, David Waldman of Rojo’s Roastery in New Jersey, and yours truly.  Just listening to coffee guys talk about coffee was quite a learning experience. I was glad that I could keep up with a lot of it, and that I was able to make some contributions from a consumer and ecological viewpoint.

George and I, in fact, had several great talks about some of the pros, cons, and the future of various certifications, and he was very gracious about answering my questions. He gave a really lively presentation on the many points from crop to cup where quality can fall off. I was once again amazed that we ever end up with a decent cup of coffee, much less brilliantly delicious cups. And also again, I am sure that if more people know the many steps involved in bringing this crop to market, and the intense labor that goes into it, that they’d be willing to pay a lot more for it. As they should.

I asked Hacienda La Esmeralda’s Price Peterson some coffee-growing advice. I brought home some beans from Panama last winter, and have five little plants growing right now. A couple of them are looking a little anemic. Price was a bit stumped and was not sure exactly what to recommend. The guy can grow some of the most lauded and expensive coffee in the world, but didn’t know what to tell me about some mundane Caturra growing under lights at 193 meters in Michigan.

It was a really great conference, and all the other participants I talked to agreed. The small size allowed for a lot of interaction and discussion. Its interdisciplinary nature, and the varied backgrounds of participants made for a wide range of opinions as well more balance. There is a plan for a book derived from the proceedings which I look forward to. Kudos to the organizers, especially Robert Thurston. I’ll be incorporating more information from the conference into future posts, especially regarding the backlash against certifications.
