Biodiversity and Linguistic Diversity Correlate!

From 2 – 14 November 2023, Azim Premji University is hosting a magnificent festival Forests of Life – “a climate festival that celebrates the joy of nature.” This post celebrates the linguistic diversity of the Indigenous world.
Imagine that you speak one of these languages:
• You don’t say “my left arm”. Instead, you say “my north / south / east / or west arm”, depending on your actual orientation! Speakers of Warlpiri in Central Australia use the cardinal directions; an absolute frame of reference. (Levinson and Wilkins, 2006)
• You must use one of 10 genders! Yuchi in Oklahoma, USA, use “six for Yuchi people (depending on kinship relationships to the speaker), one for non-Yuchis and animals, and three for inanimate objects (horizontal, vertical and round )”! (The Guardian, 2008)
Those are just two of the wonderful ways the approximately 7000 languages of the world describe the world. And there is more!
Look at the places of high biodiversity in the world;
Number of languages spoken in some of the high biodiversity places in the world
- 839 Papua New Guinea
- 704 Indonesia
- 90 Arunachal Pradesh
Biodiversity hotspots correlate with linguistic diversity!
The biocultural link here is that the knowledge to sustainably manage this biodiversity is encoded in these Indigenous languages. So, even for purely “selfish” reasons, the world must make sure that Indigenous languages flourish.
And how can we do that? Many things are needed, but schooling is clearly one place to start. Bringing mother tongues into schooling will make all education more effective. It will revitalize Indigenous languages as modern-knowledge languages, while its speakers continue to take pride in their cultural heritage.
Meanwhile, apart from learning in their own languages, children also need high-quality teaching in the other languages that they need to know – the regional language and English, for example. This idea is at the core of Mother Tongue Based Multilingual Education (Mohanty et al., 2009).
In itself, this is not enough. The rights of Indigenous peoples need to be strengthened in many other domains. But whatever strategy societies adopt, education is a key component. Only then will generations to come continue to marvel at these diverse ways of being human!
