RIO DE JANEIRO (AP) — Shaking a traditional rattle, Brazil’s incoming head of Indigenous affairs recently walked through every corner of the agency’s headquarters — even its coffee room — as she invoked help from ancestors during a ritual cleansing.

The ritual carried extra meaning for Joenia Wapichana, Brazil’s first Indigenous woman to command the agency charged with protecting the Amazon rainforest and its people. Once she is sworn in next month under newly inaugurated President Luiz Inácio Lula da Silva, Wapichana promises to clean house at an agency that critics say has allowed the Amazon’s resources to be exploited at the expense of the environment.

Environmentalists, Indigenous people and voters sympathetic to their causes were important to Lula’s narrow victory over former President Jair Bolsonaro. Now Lula is seeking to fulfill campaign pledges he made to them on a wide range of issues, from expanding Indigenous territories to halting a surge in illegal deforestation.
