A Climate Solution? The Wisdom Passed Down Through Generations | Louise Mabulo | TED

When I was a little girl, my parents would take me outside

and show me all the incredible ways

that they would take care of our land to produce good food.

And I would begrudgingly follow them out

and listen to the stories that they had to say.

And their pieces of advice would range from totally rational and practical

to absolutely bizarre.

For example, my grandfather would say,

"Hey Louise, if you want to plant good root crops this season,

what you should do is plant some rocks underneath your sweet potatoes."

And I would look at him and be like,

“OK, Grandpa, sure. I totally believe you.”

And my grandmother would say,

"OK, to have the best harvest of fruits from the fruit-bearing trees this season,

you want to be able to plant according to lunar cycles.

You want to plan towards the full moon and never towards a new moon."

And I would look at her and say, "What?"

And my dad, most bizarrely of all,

would say, "If you want to sift rice or cocoa nibs to get rid of all the dust,

the best thing that you can do is to whistle a certain tone

to harness the wind."

And I'd be like, "Dad, like airbending?"

(Laughter)

"OK, sure."

So as I grew up, I would ask them,

"Why? Why do we do all these weird, strange things," right?

And my relatives and my family would come up to me and be like,

"Louise, here's the thing.

Your grandparents are kind of crazy. So this is just traditions.

You don't have to think about it. It's fine."

But my work has put me at the frontlines of the climate crisis,

working with communities and farmers to build resilient agroforests

that really react best

to the intense super typhoons that we experience.

I established an initiative called the Cacao Project,

which works to build these resilient agroforests

and work closely with farmers

to understand how we could best steward our ecosystems and landscapes.

And over the years, I've been able to really do my best dream job,

which is make chocolates for restoration.

And I have the best job, I know.

I get to eat chocolates, talk to farmers,

live on the land and have such a good life.

And we look at the ways

that we can marry practical, traditional knowledge techniques

with modern science and know-how,

so that we could really put a spotlight

on those simple, practical solutions that react effectively to climate change.

Now over the years I’ve trained with farmers,

and we make sure that learning is a two-way street

where we listen to the stories that they have to say,

but also be able to teach them regeneration.

So very simple concepts,

like putting more carbon back in the soil than we take from it,

or maybe planting the crops that are suited to our ecosystems

and our landscapes.

And even propagating the life

that strengthens our forests and our trees.

And as I was talking to these farmers,

these crazy stories started resurfacing,

and I said, "OK, hang on, hang on. Maybe they're on to something here."

So together with our farmers, we started kind of trying it out.

OK, let's plant some rocks here and see what happens.

OK, let's plant according to the lunar cycles.

And for some reason, every single time that we would do that,

it would work.

When we plant rocks under sweet potatoes,

they were better, sweeter, just more delicious.

Every time we planted according to lunar cycles,

we'd have delicious harvests.

And I thought, maybe, what if all of these weird stories

are just kind of decades of peer review

that has passed down from grandmother to grandson,

from father to daughter,

in the ways that they best knew how?

And maybe Grandma wasn't so crazy after all.

So I quickly learned that lunar cycles

were actually tied to insect flight activity and reproduction

that made better pollinators, so more fruits.

It was tied to irrigation and water patterns.

And I thought, wow, that is so cool.

So my grandmother had a point. I digress.

It turns out planting rocks under root crops,

it meant that you were just actually making better drainage,

but also it was creating this inviting ecosystem

for worms and little creatures to live under.

And they were just natural fertilizers.

So, awesome, Granddad was right.

And whistling for wind,

well ...

I wish I could give you a scientific explanation.

I have no idea how that works, but every time I ask my dad,

“Can you bring me out to a field and whistle?”

a light breeze would always seem to blow.

And it was magic. I was like, what is this sorcery?

So what if all of these invisible pieces of knowledge

are actually keys to how we can best curate

our stewardship to our landscapes,

how we could best create resilience in our ecosystems and forests

to react better to climate change.

And all of this knowledge exists

in countries and communities, and traditions and stories

within our families.

And as a young person who works in the environmental field,

I think it is so cool to have that kind of responsibility

to carry this knowledge on to the next generation,

to transfer this information over into our modern age

and be able to articulate why they work.

Because maybe the solutions to our climate crisis,

maybe the next big fix-all,

isn't just this one big, amazing, sparkling solution.

Maybe it exists in the soils under our feet.

Maybe it’s in the wind that blows in the air

or the sunlight that beats down on us.

Or maybe it exists in the crazy, wild stories of our grandmothers.

And it is such an honor to think that maybe these amazing solutions

are actually an opportunity for us to build something

that embodies the wisdom of our communities, of our families

and of our landscapes over years and generations.

And as a young person carrying that on,

I think, wow, we have some exciting magic in our planet to offer,

and hopefully we can harness that power

and all this sorcery and secret bits of knowledge

to do something really great with it in different parts of the world

that curate our stewardship to our planet.

With that, thank you.
