The Urarina, who call themselves "Kachá", meaning "the people," are a semi-nomadic Amazonian people who have inhabited the Chambira and Urituyacu river basins north of the Marañon river in Peru for at least 500 years. The Urarina and the Mayorunas (Matses) remain the largest untitled Amazonian Indigenous groups in Peru. However, the relative isolation of the Urarina has been interrupted as their traditional territory has been invaded by colonists, loggers, river traders, and drug-voyeur tourists. All of these groups have brought significant disease pressure on the Urarina that threatens their way of life and survival as documented in the article published in Abya Yala News Vol. 10, Number 2 (Summer 1996).
The most recent and grave threat to Urarina survival is disease importation caused by the three multinational oil companies who entered their territory in late January 1997 to build an oil drilling site for petroleum extraction.
Enterprise subcontracted Parker Oil Drilling Co. of Tulsa, Oklahoma, and the Santa Fe Petroleum Co. of Lima, to drill the Santa Martha well. Construction of the oil field started in January, 1997 and by May 1, Enterprise/Parker/Santa Fe had drilled a complete well but fortunately did not encounter enough oil to warrant further exploration. The latest news is that the company has moved to lot 32, which is just northwest of their original site and is still deep in Urarina territory, to pursue further exploration in the next two years with a government contract.
Pertussis appeared last February in the Chambira, after drilling had started- it was almost certainly brought by the oil teams. At least seven persons died from the two villages around Santa Martha. The Urarina have not received the DTP vaccine which protects from pertussis, and pertussis can be among the most lethal diseases in children with multiple infections.
Over sixty percent of the P. falciparum strains in Santa Clara near to Iquitos are resistant to chloroquine and pyrimethamine/sulfadoxine, the two cheapest and most used drugs against P. falciparum in Peru. The P. falciparum strains in the Chambira river still respond to pyrimethamine /sulfadoxine, but supplies are small and infrequent. There is a very real danger that resistant P. falciparum strains are being transported to the Chambira by the oil workers loading the supply barges in Santa Clara.
The Peruvian government has no health post in the entire Chambira river basin. The nearest health post is in Maypuco, more than 1 week by canoe from Urarina territory. Colonists on the lower Chambira have access to boats and motors which can shuttle sick persons to Maypuco and on to Iquitos. The Urarina have no transportation except canoes.
As of May 1997, the Peruvian non-governmental organization CEDIA (Centro Para el Desarrollo del Indígena Amazónico) had counted over 3,200 Urarina in the Chambira basin alone (there are also Urarina in the Uritiyacu river and in affluents of the Corrientes river). The final number will likely include over 4,000 individuals, a large number for a remote Amazonian people.
Even though it has only just begun, the oil exploitation in Urarina
territory has resulted in both serious health impacts and environmental
degradation. If it continues at this pace, the cultural, biological, and
ecological effects of oil exploration on the Urarina will likely be
irreversible.
The Urarina do not marry outside their group and sexually transmitted diseases
including AIDS are not yet a problem in the communities. Cultural breakdown
from exposure to oil workers may alter this trend. New drug resistant strains
of malaria brought in by oil workers will take away any hope of controlling
the P. falciparum epidemic that is currently decimating the Urarina people.
Implimentation of Convention 169, of which Peru is a signatory nation (1994)
would help to protect the cultural rights of the Urarina as well as legally
title their land. Legal recognition of their territorial boundaries would
lead to self determination for the Urarina giving them some recourse to
protect their way of life.
R. Witzig has performed medical surveys, disease treatment, supplied
medicines, and trained Urarina village health workers (VHW) in basic medical
and public health on seven separate trips to the Chambira basin since 1992,
with a total of 13 months in the field. This continuing project which the
author founded is the Amazonian Indigenous People's Health Project (AIPHP).
The author has documented the epidemics of measles, acute respiratory
illnesses,
cholera, and malaria affecting the Urarina. His previous trip in May, 1997,
found one of the three VHW's dead from malaria, and widespread malaria
in the entire Chambira basin. This was the first trip after the oil drilling
started, and all of the Urarina communities were traumatized by the incursion
of heavy equipment into their river. The pertussis epidemic in the communities
around the oil drilling site was documented, which the oil workers likely
introduced. Seven Urarina had died of pertussis in those villages alone
since February 1997. The author is the only person (domestic or foreign)
to work with the Urarina to document and treat their medical problems.
The authors are currently iworking on malaria projects in Iquitos, Peru.
