Enhancing Western and Non-Western Nature-Based Solutions And Relationships




Our Goal


This N-EWN project is a collaboration between the U.S. Army Corps of Engineers (USACE) Tribal Nations Technical Center of Expertise (TNTCX), the USACE Network for Engineering with Nature (N-EWN), and the University of Georgia (UGA). The project proponents are seeking collaboration with interested Tribal communities in the development of methodologies for the co-production of natural infrastructure in water resource planning programs and projects in Indian Country. In collaboration with our Tribal partners we are seeking guidance on weaving Indigenous and engineering ontologies, knowledge, and ways of managing resources into Federal decision making.

Listening Groups


In collaboration with tribal and other community partners, we will conduct two regional (East and West) listening sessions/focus groups to identify themes common to water infrastructure management and decision making in Indian Country. The first session was held in Calera, Oklahoma on September 28th and 29th. Summary report coming soon!



Who We Are


The United States Army Corps of Engineers Tribal Nations Technical Center of Expertise (TNTCX) was established in order to improve USACE’s quality and effectiveness in delivering USACE missions and Federal Trust responsibilities to
Federally recognized tribes. In this role, the TNTCX engages with each of the 574 Federally recognized Native American Tribes, national and regional organizations representing Native American governments, Native American communities,
and the USACE Commands serving those communities.
