the wall street journal, 9. october, 1998

During the darkest years of this country's 35-year civil war, local
farmers (in guatemala) abandoned their land. As the farms became jungle
again and pesticides leached away, wild spieces thrived. At the same
time, a new market in North America and Western Europe was creating
demand for organic produce.
Guatemala's civil war, ironically, was environmentally correct --
it helped reclaim the country's native plants. But these plants are not
just an environmentalist's dream; they have become a meaningful source
of income for some guatemalan peasants who are capitalizing on the
growth in the organic products market. These farmers have learned of
the comparative advantages of selling organic premium-priced goods,
making them some of the country's first enviro-capitalists.
Thomas Fricke, the president of ForesTrade, a vermont-based trading
company specializing in organic spices, coffee, and essential oils from
around the world has connected with the guatemalan farmers. Founded in
1995, ForesTrade began by imprting organic cinnamon, pepper, cloves,
nutmeg, macem and ginger from Indonesia and Sri Lanka, buying
exclusively from small-scale farmers. Mr. Fricke knew the trend:
organic produce markets in the u.s. and europe had been growing at a
rate of over 20% annually since 1990, with an estimated $3.3 billion in
the u.s. sales alone in 1996. Meanwhile, the ethnic cuisine craze was
prompting more americans to experiment with spices that were once
considered exotic. Responding to increasing demand from customers,
ForesTrade went searching for supply and found some of Latin America's
healthiest soil in Guatemala.
"We received organic certification for cardamom (a staple spice for
Indian food) in several months," Mr. Fricke says. "This process can
take 3 years in more chemically-laden countries."
Not long ago, U.S. consumers and lucrative organic produce markets
seemed far beyond the reach of farmers here, 95% of whom speak only
Kekchi, a Maya tongue. Chronic market inefficiencies, typical in the
Latin American countryside, together with the language barrier, had
impoverished rural producers, which arguably gave impetus to the longest
civil war in latin american history. When peace finally came in 1996,
local farmers benefited from an ironic twist of fate: u.s. and european
buyers were paying premiums for certified "organic" labels that
guarantee the absence of synthetic pesticides, fungicides, and
herbicides in agricultural production. Their cardamom plants, which
thrive under tall rainforest canopies, fatch even higher prices.
This is a typical tropical economy. Agricultur contributes 24% of
gross domestic product (estimated at $16 billion last year) and accounts
for 75% of exports. But selling eco-sensitive produce into the global
marketplace offers guatemala the chance to compete on something besides
price -- which it would ordinarily do in the commodity market. In this
case, guatemala has a comparative advantage in organic coffee, cacao,
spices, and natural dyes and can thus command premium prices. Though
the market today is small, its develoment in rural areas might have an
important significance for farmers who otherwise would have to compete
in commodities.
For products like spices and coffee, organic farming requires a
shift away from the large plantations carved out of the rain forest to
the smaller farms where cardamom plants, for instance, are grown. In
Las Conchas, this shift has proved a boon to peasant farmers. As
Herminio Gonzalez, a former guerrilla turned organic spice farmer
explains, "Nobody around here can afford to manage our plants and
control pests with expensive chemicals or tractors. Today, with this
new market, we can do well with machetes and sweat equity."
Because Mr. Fricke needs a supply of organic produce, he pays
premium prices and provides technical support to heighten farmer
productivity. To reach their remote suppliers, ForesTrade establishes
joint ventures with existing businesses, individual entrepreneurs,
community associations, and non-governmental organizations. Through
this network, the company forms contractual linkages with small-scale
producers. It also hires U.S. "organic" certification agencies (with
representatives in Central America) to inspect the farms and monitor
product as it moves from the field to intermediary buyers to exporters.
Revenues at ForesTrade are still modest. While the compny has
established strong market links with conventional spice and specialty
coffee companies and leading natural food stores in North America and
Europe, their forecasted sales will fall just shy of $3 million for this
year and are expected to approach only $6.5 million by 2000. Still,
this will rank them among the largest-volume producers and importers of
certified organic spices in the world.
While numerous other U.S.companies are importing organic produce
from small-scale farmers throughout central america -- the organic
commodities project (cacao), equal exchange (coffee), stonyfield farms
(mangos) -- the case of guatemala merits special attention. Full
implementation of the peace accords, signed by the government and the
rebel alliance on 29. december, 1996, is the greatest challenge facing
guatemala today. People in places like Las Conchas are focused on the
economic underpinnings of peace.
At the end of this year, the support that many ex-guerrillas
received over the last three years from the u.n. high commission for
refugees to resettle and rehabilitate their farms is ending. U.S.
official assistance to guatemala, totaling about $965 million since
1986, is also drying up. Yet it is not more aid that the veterans of
guatemala's civil war need, but access to markets, especially ones that
promote grassroots development.
The story in Las Conchas in typical of the remote jungle
territories in northern guatemala: indian peasants -- many of whom are
former rebels -- returning home after being internally-displaced during
the civil war; new thatch huts popping up along lonely dirt roads; the
gray haze from forest fires that ripped across guatemala's tropical
forests this summer. What is exceptional is that unlike most other
places in the country, the humid forests here remain largely intact
thanks to a local campaign against an ingrained culture of
slash-and-burn agriculture. What's more surprising is that the jungle
still stand, and the farmers are living better, thanks to what most
former guerrillas would consider a dirty word: the American consumer.
