U'wa people block Occidental Petroleum (Colombia), 1995-2001

Summary

From late 1995 to May 2001, the U’wa people of Colombia, supported by a transnational network of environmental and human rights organizations, campaigned to prevent Occidental Petroleum (Oxy) from drilling for oil on their ancestral lands. [source: nv-database] Through legal challenges, international solidarity actions, protests, and direct nonviolent occupations, they pressured Oxy to abandon its drilling plans. [source: nv-database] The campaign achieved its immediate goal when Oxy withdrew in 2001, though the company cited lack of oil, and the U’wa remained wary of future incursions. [source: nv-database]

Tactics used

Background

The U’wa people have lived in the Colombian Andes for centuries, and they consider oil the blood of Mother Earth. In the early 1990s, Occidental Petroleum (Oxy) negotiated with the Colombian government for oil exploration rights on U’wa traditional lands, and by 1995 the government granted Oxy a license for the Samore block. Despite legal protections for indigenous territories, the government prioritized potential oil revenues, prompting the U’wa to resist the development.

What happened

In October 1995, a tribunal ruled in favor of the U’wa, but the Supreme Court overturned the decision [source: nv-database]. The U’wa spiritual leaders threatened mass suicide, echoing a 17th-century resistance [source: nv-database]. In August 1996, U’wa Senator Lorenzo Muelas organized a forum that attracted international attention [source: nv-database]. In spring 1997, the Ombudsman’s Office filed a suit; the Constitutional Court ruled U’wa rights were violated, but the Council of State approved Oxy’s license [source: nv-database]. In April 1997, nearly 3,000 students, environmentalists, and U’wa marched to the Ministry of the Environment in Bogotá [source: nv-database]. In May 1997, U’wa leaders began speaking tours in the US and Europe, building a transnational network [source: nv-database]. In June 1997, the U’wa Defense Project was formed, organizing negative publicity campaigns and protests at Oxy shareholder meetings [source: nv-database]. In February 1998, Shell withdrew from the project after receiving thousands of protest letters [source: nv-database]. In August 1999, Colombia granted the U’wa a unified reservation that excluded the proposed drill site [source: nv-database]. In November 1999, over 200 U’wa and farmers occupied the Gibraltar I drill site; police attacked with tear gas, and three children died [source: nv-database]. In January 2000, Colombian troops removed all occupiers [source: nv-database]. The U’wa then called three peasant strikes that halted the local economy [source: nv-database]. In May 2000, a U’wa petition challenging Oxy’s license was rejected, and renewed direct actions included road blockades [source: nv-database]. At the May 2001 shareholders meeting, Oxy announced it would abandon drilling, claiming insufficient oil, though subsequent test wells were not drilled [source: nv-database]. The transnational network quickly diminished, and by October 2002, Ecopetrol began oil activities on U’wa territory [source: nv-database].

Outcome

Verdict: partial.

The campaign achieved its immediate goal when Occidental Petroleum withdrew from U’wa land in 2001, but the company cited lack of oil rather than conceding to the campaign’s demands. The U’wa remained suspicious, and within a year the Colombian state oil company Ecopetrol began similar operations, indicating that the broader struggle for indigenous sovereignty was not fully resolved.

Lessons

  • Building a transnational advocacy network can amplify local resistance and create significant pressure on multinational corporations.
  • Combining legal strategies with direct nonviolent action and international solidarity campaigns can force corporate withdrawal even when legal victories are overturned [source: nv-database]
  • Sustained campaign infrastructure is needed to prevent the re-emergence of similar threats after a tactical victory.
