Maijuna Lands


The Maijuna, also known as the Orejón, are an endangered and marginalized indigenous group found in the northeastern Peruvian Amazon. Today, there are only 400 Maijuna individuals left living in four villages in a large area between the Napo and Putumayo Rivers.

The Maijuna have organized themselves into an indigenous federation and their leaders have requested the assistance of EfID in helping to improve the health and wellbeing of their communities. 

The Need

Residents of the four Maijuna villages get their drinking, cooking, and cleaning water directly from rivers which results in a wide variety of human health issues, including infant mortality and wide spread issues with dysentery.  Additionally, the lack of latrines and proper hygiene exacerbates the human health challenges that their communities are experiencing.  

EfID Response

In January 2012, an assessment trip was made by two Mason faculty members and two EfID students to gather data on the water, sanitation, and hygiene challenges of each of the Maijuna communities.  During this time, a collaborative and community-based project was developed to help the Maijuna address their water, sanitation, and hygiene challenges. 

In June 2012, two Mason faculty members and seven EfID students traveled to one of the Maijuna villages to begin the project.  A pilot BioSand filter was successfully constructed showing proof of concept and hygiene education lessons were conducted in each of the village households.
