Month: May 2012

Sips: Climate impact and adaptation, FT4All evaluation

Recent coffee news. (I’m behind. I should just let everybody know that May is a month my day job prevents me from doing anything related to coffee except drinking it!)

Know your coffee birds: Ovenbird

The Ovenbird (Seiurus aurocapillus) is often heard before it is seen, a loud ringing “tea-cher, TEA-cher, TEA-CHER!” broadcast from close to the forest floor through much of the eastern U.S. and Canada during the nesting season. Ovenbirds are large warblers, no relation to the Ovenbird family Furnariidae found in the tropics. However, both the warbler and the family share a basic brown color palette, and are named for their curious domed, Dutch oven-like nests which, in the case of the warbler, are build on the ground.

Ovenbirds winter primarily in the Caribbean and Central America. There, they forage on or close to the ground, where much of their diet is comprised of ants. This habit of scratching and leaf-flicking on the forest floor has earned them the name “Betsy Kick-up” in Jamaica! Ovenbirds are frequently found in shade coffee plantations, where they may also feed on female coffee berry borers that are laying eggs in fallen coffee cherries, thus performing a great service to coffee farmers.

Migrant (and resident) bird species have been monitored in Puerto Rico since 1973 in a study where Ovenbirds have been one of the most common species. Their numbers have declined to less than 20% of their original abundance. Some of the declines are related to variable rainfall patterns (which will be exacerbated by climate change), and some to conditions on their breeding grounds (see below). But similar declines in resident Puerto Rican birds in the same study indicate there are undiscovered factors occurring on the wintering grounds as well.

On their North American breeding grounds, Ovenbirds need large forests to breed in, and habitat loss and fragmentation has taken its toll. Even in large forests in northern regions, declines in reproductive success are tied to, believe it or not, earthworms.

Due to the last glaciation, Canada, the upper Midwest, and New England have no native earthworms — all of the worms are introduced. Their efficient consumption of leaf litter on the forest floor has greatly altered many forests. Plants that require a thick organic layer in some forests have declined, leaving less cover for Ovenbird nests, which then fall to predators. Ovenbirds also rely on the insects and invertebrates that live in leaf litter, which are also far less abundant in habitats invaded by non-native worms. These factors are thought to be driving declines in some breeding populations of Ovenbirds.

Ovenbirds found on shade coffee farms help farmers by eating pests, and have found safe haven in winter. Choosing shade-grown coffee can help support populations of this charismatic songbird so that future generations can enjoy its distinctive summer song.

Finca Dos Gatos…harvest!

Finally, ripe cherries!

This is my third post regarding my growing (literally) little coffee farm in southeast Michigan. My first post, Growing coffee at home, documented my initial attempts at germinating coffee beans I collected on a trip to Panama in January 2008, one of which flowered in April 2011. My second post, Update on Finca Dos Gatos, covered the bean development, transplanting, and other outdoor accommodations.  Here is one more update.

Panama plants

These were my original plants, which I grew from seed collected around Volcan, Panama. The chronology:

  • Seeds harvested from ripe cherries in January 2008.
  • Seeds germinated in May 2008.
  • First flower buds: 12 April 2011, only on one plant.
  • Flowers opened 25 May 2011.
  • Two fruit begin to develop 15 July 2011.
  • Fruit full size, but green September 2011.
  • Fruit finally begins to ripen mid-February 2012.
  • Fully ripe and harvested by mid-March.

The last interesting thing about this crop was that after I picked the cherries and removed the skin, I discovered that both contained peaberries instead of two flat beans. This occurs due to one of the ovules not developing, usually from lack of fertilization. Arabica coffee is self-pollinating, but perhaps this is to be expected when there are only two flowers! After the two beans dried, I noticed they are much less dense than a normal bean…nearly as light as a roasted bean. My first crop is just souvenirs.

Nicaragua plants

I have collected seeds twice from Nicaragua. My first batch was from Finca Esperanza Verde which I planted in March 2009. These germinated in June 2009, and now have their first flower buds. I have three plants and have given others away.

The second set was collected in March 2011 from El Jaguar and Selva Negra; they germinated in mid-May 2011. I’ve given away some seedlings and have chosen to keep just two plants: one from Selva Negra and one of the yellow catuai variety from El Jaguar.

In November, I performed an experiment where I provided a “dry season” for the Panama and first batch of Nicaraguan plants. I restricted water for a couple weeks, then stop watering for three weeks. Then, I watered like crazy, and began switching over the fertilizer from the Earth Juice ”Grow” to the Earth Juice “Bloom”.  Further, I swapped out half the lights in the system to 3000K red spectrum bulbs instead of 6500K blue lights (Sun Blaze T5 in four-foot fluorescent fixtures).

And sure enough, I have a ton of flower buds, which began to develop in early February. Although the first time around, the buds developed quickly, in a month, so far all the buds I have are growing slowly, and have not yet opened.

Honduras – new additions

In November 2011, I was in Honduras. This trip was not to coffee farms, as we were staying in a lowland area on the northern coast. However, there was coffee growing in the region, and I picked up cherry from a semi-tended plot owned by the Lodge at Pico Bonito that had both coffee and cacao, as well as some at Pico Bonito itself. Traditional old varieties of arabica coffee don’t grown at this altitude with the heat and humidity. I figured it must be some varietal that included robusta heritage, and Daniel Humphries identified it from photos as catimor, a hybrid between caturra and Hybrido de Timor (itself a naturally-occurring hybrid between arabica and robusta).

In Honduras, two lines of catimor are common. One is IHCAFE 90, released in the 1990s and derived from the T5175 line out of Portugal or Brazil. The other is Lempira, from the T8667 line out of Brazil.

I had a bunch of it sprout by mid-January, and gave away some seedlings, saving a couple for myself.

Cacao

Okay, this is a coffee “finca” but I had to see if I could also grow some cacao, which was growing all over the place, including outside our cabin and next to the coffee. Here are some trees at Pico Bonito with their bizarre unripe pods.

These pods are tough and leathery and often have to be opened with a machete, but animals had opened some and we were able to retrieve the large seeds. I read that they must always be kept warm and moist, so I wrapped them in damp paper towels. No long wait like coffee. By the time I got home a few days later, they were beginning to sprout.

By early December, I had little plants about five inches tall.

In order to maintain a little more warmth and humidity, I constructed a little enclosure for the three cacao plants by wrapping overhead transparency plastic around a wire bird feeder squirrel-excluder. It sits on top of a cheap, twelve-inch plastic flower pot saucer. Another saucer went on top.

I look forward to bringing the finca outdoors for the summer, when I know everything will take off; the cacao should especially enjoy our hot, humid Michigan summer.  Perhaps I’ll do one more update with photos of more of my coffee in flower, and any resulting crop.

Additional sustainability-related awards

I previously reported on the Rainforest Alliance Cupping for Quality award that was presented at the Specialty Coffee Association of America’s (SCAA) annual trade show in Portland, Oregon late last month. There were several other awards relating to sustainability handed out at the SCAA meeting, and here are a few of them.

Rainforest Alliance Change Agent Award
This is a new award, and will honor coffee industry sustainability champions. It will be presented at the same breakfast as the Cupping for Quality awards each year at the SCAA event. The first recipient is Chad Trewick, Director of Coffee and Tea for Caribou Coffee. Chad has been a driving force in Caribou’s  encouragement of  farmers worldwide to achieve Rainforest Alliance certification. As reported earlier, Caribou is the first major U.S. coffeehouse to source 100% Rainforest Alliance certified coffee. Here is an interview Chad gave after his award, and another he did earlier with RA.

SCAA Sustainability Award
This is given annually by SCAA’s Sustainability Council, and went this year to Thanksgiving Coffee Company for their project “Responding to Climate Change: Building Community-Based Reliance.”  Thanksgiving worked with Rwanda’s Dukunde Kawa Cooperative, which has over 1800 producers, doing site-specific climate risk assessments, and deploying best practices such as shade intercropping, erosion control, and watershed conservation. A full description of the project is here.

Descriptions of some of the previous winners can be found here, here, and  here.

Best New Product and People’s Choice Award – Equipment for Origin
C-sar Online Tools by Cropster GmbH, for their online database system that helps producers track, manage and improve quality; communicate and collaborate with partners and customers; and assists with certifications, accounting, and other logistics. I’m all for transparency, traceability, and tools for farmers.

The Best New Product – Sustainability was not awarded this year, but the Best New Product – Packaging was sustainability related: the Natural Kraft Biotre Side Gusseted Bag by Pacific Bag. There is a fair amount of both interest and confusion on sustainable (especially biodegradable) packaging products, so I thought it was worth a mention.

This bag is  made of Biotre film 60% (by weight) biodegradable materials made from renewable resources such as wood pulp. Pacific Bag says the outer paper portion will break down in several months in a backyard compost pile. They have a series of videos on YouTube that show the paper portion was gone in about five weeks. The rest of the bag is a polymer film (derived from fossil fuels, unfortunately) that is supposed to take a five to ten years to degrade in a “landfill environment.”

Two things need to be pointed out here. First, if only part of this bag (which also has a degassing valve which is not biodegradable) will break down in your backyard compost pile, why would you put it in there in the first place? Off to the landfill it goes. Second, I think that if it were to go to a large commercial composting unit of a landfill, then the bag might break down in five to ten years. It seems unlikely that it will break down much at all in a typical municipal landfill, which are packed very tightly and do not allow much or any aerobic activity which is required for most biodegradation. So, another product that is a step in the right direction, but no silver bullet.

Congratulations to all individuals and companies working towards sustainability in the coffee industry.
