AUDIO: In addition, the project contributes to conserving and maintaining biodiversity, as well as adapting and becoming more resilient to climate change

Palcacocha glacier, Cordillera Blanca, Peru

AUDIO
Speaker 1:
Peru is interesting it contains about 70 percent of the world's tropical glaciers.
As you can imagine the tropics isn't a great place for glaciers.
Many mountain regions around the world are warming at much higher than the global average
and that's true also in Peru.
VISUAL
Palcacocha glacier

AUDIO
Speaker 1 (Jemma Wadham):
Glaciers in Peru have been retreating,
over the last few decades they've lost about 30 percent of their area.

AUDIO
The very special thing about Peruvian glaciers is actually they are vital as a water resource for the region.
So during the rainy season the glaciers receive snowfall and they're nourished,
and in the dry season, when there's less rain, they then melt and continue to provide meltwater for local communities.
VISUAL
Palcacocha glacier

AUDIO
So they really buffer a kind of low water supply during the dry season when the rain stops.
So they're really, really important in providing water to people to croplands, to animals as well.
VISUAL
Jemma Wadham sitting in chair

AUDIO
With any big grand environmental challenge it's so much more powerful to be able to bring
people together,
across disciplines across borders and I think the project we're running is a unique example of that.
So I'm a glaciologist from the UK, I've done a lot of work on glaciers,
VISUAL
Three researchers walking towards Palcacocha glacier

AUDIO
Raul Loayza-Muro, my collaborator in Peru, he's an ecotoxicologist,
so he's very up on the impact of water quality on people and an ecosystem
so together we actually bring a really unique set of skills together,
which enables us to kind of address this grand challenge about water quality and glassy retreat in Peru.
VISUAL
Two researchers sit and examine rocks

AUDIO
The glaciers in the Cordillera Blanca they sit on top of these rocks which are very metal rich
As the glaciers are retreating they are exposing those rocks in front of them, they get washed
by the rain,
they're open to the atmosphere, the metals get dissolved out of the rock sand and that process produces acid.
So the rivers are becoming acidic and very metal toxic.
VISUAL

AUDIO
What we don't know is which rivers that's going to happen to, which rivers that's not going to happen to.
VISUAL
River flowing

AUDIO
So what we're hoping to do through our project is to produce a vulnerability map of that whole region for the water resource managers.
So they can see which rivers are going to be a problem as the glaciers retreat, which ones we don't think will be a problem,
and then on the flip side of that, to work with these communities to help them to remediate
some of the toxic waters in the rivers which is happening due to glacier retreat.
VISUAL
Researchers working by river and collecting and analysing samples

AUDIO
So they're constructing artificial wetlands, and by working with these communities I think what's quite nice,
is actually we're kind of implementing a solution to the problem,
rather than just diagnosing the fact that there is a water quality problem in the mountains
in that region.
VISUAL
Researchers and local community members discuss the problem together on a mountain in Peru

AUDIO
Speaker 2 (Dr Raul Loayza-Muro):
Wetlands are ecosystems that are unique to high-altitude Andes. They are characterised by native
Flora, consisting of moss and grasses.

AUDIO
This ecosystem is like a sponge that keeps water and also filters the water.
VISUAL

AUDIO
So learning about the functioning of these ecosystems make us think about designing green infrastructure.
One example what happens here in the Shallap catchment. Glacier retreats has produced oxidation, acidification of water and transport of metals.
VISUAL

AUDIO
This has been channelized down to an artificial wetland, where we are aiming to treat a part of this acid water coming from the upper parts,
VISUAL
Dr Raul Loayza-Muro

AUDIO
so we can improve the quality, delivering water to reservoirs, so that local people can use this water for their lands, for crops for example, for cattle raising.

Speaker 1 (Jemma Wadham):
May the memory of my people not rage against me.
I never wanted to murder the valley.
And let everyone know, I did not cause my own death
So this evening I’m about to perform in a play about changing glaciers in Peru,
where I will actually be becoming the glacier.

AUDIO
So the performance is linked to a programme called Trans.MISSION. It's jointly funded by the Natural Environment Research Council in the in the UK,
with the Hay Festival, which is one of the world's greatest literary festivals,
and Hay kind of paired me with a storyteller and actress in Peru, which is Erica Stockholm,
VISUAL

AUDIO
and she's written a beautiful story about the changing glaciers from the scientific results that I've kind of discussed with her.
VISUAL
Erica Stockholm and Dr Raul Loayza-Muro address an audience

AUDIO
I really think that there should be more collaboration between scientists and artists
because I think at the moment it's pretty clear that the science messages about what's happening
need to get out there in a more accessible way,
and artists have a brilliant way of doing that actually and there's something quite powerful what happens when art meets science
VISUAL
Jemma Wadham performs on stage

AUDIO
I really believe that if people come together across disciplines and across different nations, that you can actually solve some of these problems.
You will come to a problem with a different mindset and a different skill set,
and actually these kind of projects, they help you open up a little bit
and see things from another perspective, to bring in different types of solution
so I really, really believe that international cooperation is key with solving grands environmental challenges.
