Language Acquisition: Knowledge that Empowers

Indigenous Epistemology

Traditional behaviors are shaped by indigenous epistemologies or traditional way of thinking, creating, and conveying

knowledge.

Indigenous epistemologies are alive and well and are also relevant and useful to

the societies to whom they belong

Cultural Values

Cultures and Languages is a storehouse of Indigenous Wisdom (IW)

Loss of biological resources is a threat to the survival of IW, cultures and languages

IW is key to scientific discoveries and basic to understanding of the natural world

IW can be restored through local, national and international collaborative efforts

Educational programs greatly help with this work

Languages & cultures provide understanding of biosphere on which we

depend for survival

Indigenous epistemology is acquired through daily experimentation and

practice

Cultures transmit indigenous wisdom

Explicit Knowledge

Knowledge that is easy to communicate “know what” (facts); “know why” (science);

“know who” (networking)

Tacit Knowledge

Knowledge that is hard to access, provides context, highly valuable,

and is not easily shared

Codification

Process of transforming tacit knowledge into explicit knowledge through training and direct

experience

Codification

Will Indigenous Will Indigenous Wisdom Survive the Wisdom Survive the

2121stst Century? Century?

2. Loss of biodiversity means loss of languages and cultures

And deeper understanding of the natural world…

Would smell as sweet.”(Romeo & Juliet, Act ii, Scene 1)

The Convergence of Indigenous & Scientific Taxonomy

The Convergence of Indigenous & Scientific Taxonomy

How Are Plants Named?Prior to Linnaeus, there

was great confusion about how to name plants.

Organisms were usually grouped by common

characteristics.

Sometimes unrelated organisms with superficial

resemblances were grouped together.

Nomenclature of Breadfruit Cultivars in Samoa

Invented by Linnaeus in response to

cumbersome 18th century

systems

First used in Flora Lapponica

Expounded in Species Plantarum & used to

organize Uppsala garden

• Binomial nomenclature consists of two names: Artocarpus altilis Genus species

• International Code of Botanical Nomenclature

• Used by scientists throughout the world.
