The Amarakaeri Communal Reserve was created by an initiative of 10 indigenous communities to conserve the multitude of ecosystem services like food, shelter, medicine and water. The reserve contributes to the protection of two watersheds. This ensures the stability of lands and forests, maintaining the quality and quantity of water for the development of native communities suffering increasingly from droughts and floods. The communities have included in their plans the use of Brazil nuts as a measure to generate economic resources.
