Apart from our reforestation efforts, TFI is becoming a place where sustainable agriculture and energy practices
are being tested, displayed, and shared. We are pursuing a goal of self-sufficiency for our crew here and
to provide as much of the food for visitors and students as we can. For food that we must purchase as supplement, we buy from local residents and farmers whenever possible.
All of our cultivated food is fertilized through prepared compost and biochar material produced from onsite or local materials. Our food production projects reflect a philosophy of balancing conservation and self sufficiency.
In addition to sustainable agriculture, we are trying to shift our energy usage away from non-renewables by using wood as cooking fuel, and by harvesting methane through a biodigester system. These efforts have only
been possible through the hard work of the staff, volunteers, students, and local community.
Cultivated Food Production
At the main cabin we have a variety of medicinal and culinary herbs growing in our front veranda concrete beds,
in addition to a few vegetables and greens. Around all four of our cabins are an assortment of fruiting plants
including starfruit, manzana de agua (water apple), papaya, noni, guayabana, guava, breadfruit, avacado, citrus, coconut
in addition to the plentiful banana and plantain plants around the property.
Our covered garden (protected from the incessant rains of the wet season) is a short walk from the main cabin. We have been successfully growing a variety of greens,
sweet potatos, peppers, squash, zuccini, cucumbers, radishes, and spinach. Outside of the garden are rain tolerant crops such as
yuca, taro (a starchy tuber), frijol de palo (a type of pea), and pineapple are also being grown around the property.
A cycling crop of dried bean production is planted and harvested annually from arrested succession fern and
vine tangle areas far up the hillside in our preserve.
We rely on our compost production to fertilize the nutrient-poor, clay-heavy tropicals soils we have to work with. We have a constant rotation of five, cubic meter piles with a turnover time from fresh
material to use in soil of about one month. All of our garden beds, newly planted fruit trees, and anything else requiring fertile soil uses
this prepared compost. Our compost generally consists of sheep manure and sawdust from local sources, as well as food scraps, and leaves
from the property. In addition to the compost, we've most recently built a biochar system, turning wood shavings into fine-textured charcoal which helps to retain
soil nutrients, as well as fix carbon in a stable form. The wood chips are sourced from a lumber mill just down the road.
Animal Husbandry
We raise several different kind animals at TFI to provide our staff and students with local and responsibly produced meat.
We raise our animals efficiently and effectively to reduce feed expenses, as well as provide for the health and comfort of the animals. We let our animals forage free-range when possible,
and provide them food primarily from fruits, tubers, or foliage grown on our land. All animal waste is reused either in compost,
our biodigester, or for those that forage the property, it is left simply to fertilize our trees and gardens.
Chickens -
We have between fifteen and twenty laying chickens, along with a rotation of "meat" chickens.
All of our laying chickens are "free-range" and roam the property during the day gleaning the vast majority of their own food. They return to their open coop at night.
Pigs -
We are raising two confined pigs at a time, who are fed on a variety of locally available fruits and tubers, along with a fermented corn and mulberry soup.
Rabbits -
We have a rabbit hutch behind the main cabin with a buck, two does, and at any time litters of up to 15 kittens up to two months of age intended as fryers.
A fenced run is attatched to the hutch and the rabbits are let out during the day to graze much of their own food, supplemented by bananas and tree leaves cut from our property.
Tilapia -
Near the main and lower cabins are four production tilapia ponds.
The diet of the tilapia is supplemented heavily with mulberry leaves. All ponds are constantly airated by hoses connected to our water supply, which is gravity fed by the steam running down the property into the guabo river.
Ducks -
Of all our animals the least maintenance is required for our three muscovy ducks, which are completely self sufficient for food. The ducks provide us with meat, occasional eggs, and most importantly, constant entertainment.
Energy Efficiency
TFI has recently begun work on projects that intend to reduce the institution's reliance on non-renewable energies,
using both creativity and traditionally practiced methods.
Wood-fired Cooking - Recently built uphill from the house in a casita
is a wood fired oven and as well as a stove. Our oven was built of river rocks and clay morter for its base, as well as sand, clay, straw and a small slab of concrete for the baking area.
Our stove was most recently constructed and was built with stone and clay mortar as the base, concrete for the firing chamber, topped with a cast iron burner surface (plantilla).
By using small amounts of wood for cooking, found in abundance on the property, we are reducing TFI's depencance on electricity
and bottled gas for cooking. The bread and pizza baked in our oven is delectable!
Methane Production for Cooking - A work in progress is our biodigester system. Housed in a section of dug-out ground lined with cinder blocks is a large plastic
bag which collects all human waste from the main cabin, as well as pig waste. The human waste is concentrated in an overflow tank,
and fed into the bag and left to break down by microbes in an anerobic environment, with the intention of producing methane. The biodigester
is not yet operational, but once finished will provide the main cabin with unpressurized gas for the cook stove.
As time, staff, and budget allow, we will strive to continue to improve our facility and attempt to reduce our
reliance on non-renewable energies, while displaying new methods to locals and sharing our food traditionals between cultures.
