Cuba's Second Revolution

For several years I have been hearing about another revolution in Cuba.
This time it involved farming and the food system. For much of the 1990's
small organic farms were providing increasing amounts of Cuba's food. They
were responding to the economic emergency of 1989-90 when the Soviet bloc
began collapsing and Cuba lost its main source of foreign exchange and half
of the food its 11 million citizens relied on.

During the early 1990's imports of agricultural machinery, fertilizer,
pesticides and other needed inputs for Cuba's industrialized agricultural
system (producing mostly sugar for export) stopped abruptly. Cuban
agriculture had to change or the people would starve. And change needed to
happen fast.

Fertilizers, pesticides, equipment and other farm inputs needed to come
from local sources and harvests had to feed Cubans, not sweeten desserts in
East Germany. It was like corporate farms in California or Iowa suddenly
having to switch from chemically-dependent monocultures feeding Manhattan
to compost-fed, diversified crops feeding Fresno or Dubuque.

Then in 1999 I read an article in The New Internationalist about a
surprising additional innovation in this latest Cuban revolution:
Organiponicos. Organiponicos are organic farms and gardens of a few
thousand square feet to several acres located in urban areas. Vacant lots,
old parking lots, abandoned building sites, spaces between roads, any
available site (even rooftops and balconies) were taken over by thousands
of new urban farmers trying to feed themselves and make some money.

In Havana alone 30,000 residents tend 8,000 community gardens and small
farms producing vegetables, fruit, eggs, medicinal plants, honey, and such
livestock as rabbits and poultry. These urban farmers produce 30% of the
city’s vegetables and perishable food. And all this produce is organic
because chemical pesticides for agriculture are not allowed within the city
limits.

Outside of Havana the Organiponico movement is also growing rapidly with
impressive results. In 1999 urban agriculture produced 46% of Cuba’s
fresh vegetables, 38% of non-citrus fruit, and 13% of its roots and tubers.
The government supports this movement by making land available, by allowing
relatively unrestricted free-market sales of the food (a market economy is
being born!), and by supporting organic research centers that are making
impressive advances in biofertilizers and biopesticides. Cuba leads the
developing world in small-scale composting, organic soil reclamation,
irrigation and crop rotation research, animal powered traction (oxen) and
other innovative practices.

I wanted to learn more, first hand, about the urban agriculture revolution
in Cuba. So in December I was able to spend several days in Havana. I
wasn't part of any official farming tour so where could I start? Easy!
Taxicabs are everywhere, and happy to provide gringos a tour of their city.
I chose a newer Mercedes because the driver was knowledgeable about urban
farming locations, though he admitted no customer had ever asked him to
tour local farms and gardens. This choice meant bypassing other interesting
taxis like 56 Chevies, 53 Fords and 49 Studebakers, but I caught rides in
these well-maintained relics of a previous era on other occasions.

The first stop on my tour was a two-acre garden at Avenida 4 and Calle 4
tended by Benito Ross and two helpers. Benito grows over a dozen salad
crops and produces 35 tons of food a year in exquisitely maintained raised
beds propped up by old slate roof tiles and drainage tiles. A large active
compost pile graces the entrance to the garden, along with thousands of
soda cans adapted as seedling starters. Benito is a succession planting
genius, with most of his crops grown and sold within 50 days of planting to
people and restaurants in the neighborhood. He uses drip irrigation and
shade netting to optimize yields in the tropical sun.

Next stop was a larger 4 to 5 acre market garden at Avenida 5 and Calle 44.
The official Organiponico billboard announces the time and days for buying
produce. This project was clearly the commercial and activity center of the
neighborhood and it had an air of government sanction and control with long
neat rows of lettuce, kale, peppers, tomatoes and cabbage in cinder block
raised beds.

My favorite garden was in the Miramar neighborhood. It was started in 1993
in a vacant lot across from a school, and students help work the garden as
part of their curriculum. Enrico Diaz, a former math teacher at the school,
is the head gardener. He, a few helpers and the students work all year to
grow 33 varieties of vegetables and medicinal plants.

All the food from this garden is donated to the elderly and poor in the
area, assuring that they get 3 good meals a day. I stayed for hours
learning about Enrico’s approaches to biological pest control and
companion planting, use of beets to absorb excess salt in the soil, use of
mustard greens to guide soil fertility improvement, and more.

Urban agriculture in Cuba offers a powerful alternative for feeding the
growing urban populations in developing countries. The lessons are many.
They are blending traditional growing methods with new, science-based
approaches to soil improvement and natural pest control. Land is made
available for growing because the value of high-quality locally-grown food
is understood. The result is every vacant lot and open piece of ground is
put to productive (and beautiful) use. Farmers are encouraged to sell
directly to consumers so they have the financial incentive to grow more and
produce it more efficiently.

The Cuban Organiponico movement just may have some lessons for us here in
the US, too. For 15 years Gardeners Supply and the Intervale Foundation
have been working in Burlington to help local organic farmers move from
producing zero to 10% of Burlington's fresh produce. We are nearly halfway
to our goal, but that’s a long way from the 30% Havana produces (even
recognizing the Vermont growing season is somewhat shorter!).
