The word permaculture
comes from permanent agriculture. Permaculture strives
for agriculture that is ecologically sound and
sustainable in the long term: this means that it should
be non-polluting, economically and socially viable, and
provide for its own needs. Permaculture uses the
inherent, or natural, qualities of plants and animals,
combined with the natural characteristics of landscapes
and structures, to produce a life- supporting system for
city and country, using the smallest area possible.
Permaculture is essentially a way of achieving efficient
and sustainable food production.
PERMACULTURE
ETHICS
* Care of the earth - means care of all living and
non-living things: soil, plants, animals, atmosphere,
water. It implies activities that do not harm, but
rehabilitate the earth, promote active conservation and
the frugal use of resources.
* Care of people - means that basic needs such as food,
shelter, education, and satisfying employment are taken
care of.
* Contribution of surplus time, money and energy to
achieve earth and people care - means that after we have
taken care of our basic needs and designed our systems
to the best of our ability, we help others to do the
same.
SOME
PERMACULTURE PRINCIPLES
Put things in the right place!
Permaculture deals with plants, animals, buildings, and
infrastructures such as the supply of water, energy and
communications. However, permaculture is not about these
elements themselves, but rather about the relationships
we can create between them by the way we place them in
the landscape.
Planning and design
are crucial to permaculture. For example, dams and water
tanks should be placed above the house and garden so
that gravity, rather than a pump, is used to direct
flow. Home windbreaks should be placed so that they
protect the home from wind, but do not shade it from
winter sun. The garden should be between the house and
the chicken pen, so that garden refuse (good chicken
food) is collected on the way to the pen, and chicken
manure is easily shovelled over the garden.
Each element has
many functions.
A dam, for example, can supply water for irrigation and
stock, be a fire control, and provide a home for fish
and waterfowl. If you choose and position the trees to
be planted around the homestead carefully, they can
fulfil many functions, e.g. a windbreak, kindling for
firewood, nectar and pollen for bees, nitrogen for the
soil (leguminous trees), seeds for poultry.
Insure yourself.
Basic needs (e.g. water, food, energy, fire protection)
should be supported by many elements. Thus a house with
a solar hot water system should also have a back-up such
as a wood burning geyser.
Make things easy
for yourself.
Areas that are visited often, such as the chicken pen
and the vegetable garden, should be positioned close to
the house. The orchard, stock pens, and sheds, which are
not visited so frequently can be placed further from the
house.
Use plants and
animals.
Plants and animals can save you energy and do work for
you. Chickens, pigs and goats can be `animal tractors'.
When enclosed in a weed infested area, they will destroy
all vegetation, while turning and manuring the soil.
Plants can play an important role in pest control.
Marigolds and daisies attract insects which feed on
garden pests. Ponds attract insect-eating frogs. Garlic
and onion tend to repel many insects. Trees and vines,
cleverly placed, can provide shade, windbreaks and
firebreaks.
Nutrient cycling.
Make sure that nutrients do not leave the farm or
garden, but are cycled through it. Turn kitchen wastes
and animal manure into compost, and leaves and dry grass
can be raked around plants to form a mulch.
Harvesting water.
South Africa is a dry country, and water is often a
limiting resource. Make the most of the water you have
by slowing down its flow and spreading it out. This will
reduce soil erosion, and give the water a good chance of
sinking into the soil where it is available for plants.
Swales (similar to contour banks, but higher) are very
useful for creating mini dams and allowing water to
penetrate the ground.
Small-scale,
intensive systems.
Cultivate the smallest possible area, and make it as
productive as possible - plan for small-scale, energy
efficient intensive systems, rather than large-scale,
energy consuming extensive systems. Use handtools (handmower,
pruning shears, wheelbarrow) on a small site, rather
than large harvesters and transport trucks.
Diversity.
Include many different animals and grow a large variety
of plants. However, it is not enough to simply have a
range of plants and animals on your farm or in your
garden - planning must take account of their functional
connections, or the way in which they work together.
The advantages of
farming with a range of plants and animals include:
meeting the nutritional needs of the people living off
the farm or garden, a wider range of saleable goods, and
reduced pest infestation.
Everything works
both ways.
Every resource can be seen as either an advantage or
disadvantage, depending how it is used. A prevailing
wind coming off the sea may be a disadvantage for
growing crops. However, if it is used to power a
wind-generator, it can be an advantage.
Using information,
not money.
Rather than relying on money, permaculture relies on
information and creativity to increase yields. In
addition to making the most of the physical resources in
a garden, or on a farm, permaculture requires that we
make the most of our ability to find useful information,
and adapt it to suit our needs. |
