What Execrises Brent Corrigan Does
Logging 9526: northern Cordoba and lost 85% of its forests
"The area studied had an annual degradation greater than those experienced by tropical forests. The international average forest loss is 15% and 85% we lost," said Marcelo Zak, a biologist at the scientific institution and author of the study.
The research, published by the Environmental Press, covered an area of \u200b\u200b27,000 square kilometers, from the Salinas Grandes to the Laguna de Mar Chiquita, north of the province.
The causes of this destruction are directly related to the expansion of the agricultural frontier in especially for the soybean crop, which resulted, among other environmental tragedies, the disappearance of Quebracho Colorado, an emblematic species of the region.
"Do not touch more than a forest in the province because there are no sufficient knowledge of economic losses caused by forest destruction," said the scientist.
went mountain forests cover 8.4% of the province, only 0.5%. The forests east of the hills of Cordoba, which covered 30 years 20.5%, now only represent 2.1%, and the West, increasing from 23% to only 5.6%, the study found .
"We studied vegetation in place and a few weeks back and found it was gone. It is very sad because it's like a death, "lamented the biologist.
" Imagine what we lost because it is a tragedy, since the structure that replaced the forests of quebracho shortens biodiversity, with fewer species. Destroy biological richness when we allow the chaotic growth of the agricultural frontier, "he added.
Local people used the forest as a supplier of basic inputs, which are lost to the advance of soy.
over 100 years ago, 25% of the provincial population lived in the north, but in 1991, residents represented less than 5%.
"In these ecosystem units, which work in harmony, the family lived modestly, but with a good quality of life," said Zak.
When landowners began to covet the land, the villagers sold them for little value. The new owners then transformed forests into agricultural land.
"This was encouraged by the increased rainfall in the north of Cordoba", which could introduce soy, without needing irrigation, it is a crop that needs a lot of rain, the biologist explained.
IMBIV investigator claimed that "some of the agricultural retention are designed to protect the forest "and questioned a cleared land is considered" improved ", which equates the value of a field with bare soil, with another forest.
Forests aquifers supply, control flooding, produce oxygen and provide habitat for wildlife, and protect soils from wind drag, a resource that takes centuries to recover since, 10 cm. of land, take over 100 years to rebuild.
"Without forests there is no water this is very simple. We live in an arid land and water deficit, however, deprive him of the mountains, "the investigador.TELAM
