| Over
the course of the last century, colonization by peasants from different
regions of Colombia, who invaded a large part of indigenous territory
in the flat, lower and middle altitudes of the Sierra Nevada, has
caused great ecological damage to the mountain. These peasants came
here fleeing the different civil wars which plagued the country.
In the 1970s and 1980s, the cultivation of marijuana for export
and later illicit coca attracted the attention of a greater number
of colonists, who formed a peasant belt around the lower and middle
elevations of the Sierra Nevada, which today is estimated to amount
to 210,000 persons. The introduction of the practice of indiscriminate
felling and burning of the rainforest, the formation of grazing
ground for cattle, the consolidation of a belt of coffee farms,
the constant extraction of hardwood, and the expansion of illicit
coca crops have destroyed the majority of the forests along with
the richness and variety of fauna and flora. Actually, only 12%
of the 21,000 square kilometers of the Sierra Nevada is intact primary
forest.
This
immense deforestation has caused erosion of the soil and the consequent
sedimentation of the rivers' watersheds, and the disappearance of
numerous species of plants and animals, many of them unique in the
world. Worse still is the loss of Sacred Sites which play an essential
role in the maintenance of the ecological equilibrium and of our
culture. When Sacred Sites are transformed by the action of the
Younger Brother, the knowledge of the Law of Origen and of the ceremonial
practices that are contained in each Site are compromised.
The
occupation of the flat, lower and middle elevations of the Sierra
Nevada has also cause the displacement of indigenous people towards
the higher reaches of the mountain, and has impeded their access
to the moderate and hot zones, thus limiting the possibility of
exercising the traditional forms of agriculture based on a vast
knowledge of the ecology of the Sierra Nevada and of astronomy.
Where our peoples have been able to maintain the traditional practice
of vertically organizing agriculture, integrating the harvesting
of different foodstuffs at the different elevations of the Sierra
Nevada (corn, yams, beans, tubors, banana, yuca in the lower regions;
arracacha, malanga, and native sugar cane in the middle elevations;
onions, garlic and potatoes in the higher altitudes) they have also
been able to maintain their cultural integrity intact. And where
our peoples have lost the possibility of maintaining the vertical
integration of agriculture they have suffered serious alterations
in their cultural identity. Agriculture is fundamentally associated
with the social fibre of our peoples. |
