Traditional Ecological Knowledge (TEK): Ideas, inspiration, and designs for ecological engineering

In coming years society will be forced to adapt to lower energy levels due to projected declines in non-renewable energies. This will increase the challenge to ecological engineers to design sustainable ecosystems, driven by renewable energies to benefit society and the environment. This paper introduces the field of Traditional Ecological Knowledge (TEK) as an important source of ideas, inspiration and designs to help our profession meet this challenge. TEK refers to ecological knowledge and practices of indigenous and local cultures. Because these practices originated and evolved prior to the era of fossil-fuel dominance, they were designed and have continuously adapted to utilize renewable energies and resources. TEK is also well suited to sustainable design due to philosophical differences with Western science and culture. While Western culture views society as apart from and controlling ecosystems, indigenous cultures routinely see themselves as embedded within ecosystems. Because TEK has declined as the influence of Western culture has spread, there is an urgent need to identify and apply this knowledge for future benefit. Collaboration with scientists can help raise the social standing of indigenous people and of TEK within their own communities, thus contributing to cultural survival while maintaining this information. Applications of TEK relevant to ecological engineering including water management and agriculture in the Americas are highlighted.
