But soon after, a brawl broke out, and it ended in the death of her nephew, Jerhy Rivera, 45, who was an Indigenous activist in the community.

Mr. Rivera’s death came just a few weeks after another Indigenous man in a nearby town was shot in a dispute over land, and a year after a land rights leader in that town was gunned down in his home.

Over the past five years, conflicts over land and natural resources in the region have led to about 200 confrontations and the deaths of 60 Indigenous people, according to the Business & Human Rights Resource Center, a London organization.

Four Indigenous people were killed in an attack in Nicaragua in January, and at least a dozen more died in Colombia in just the first two weeks of this year, according to the United Nations.

The deaths in Latin America are the result of increasingly violent clashes between people who have lived on the land for thousands of years and settlers who have arrived much more recently.
