Global warming-induced glacial melt is expected to eventually threaten the water supply of 80 million people in the Andes. I talked to some young people in Cuzco who are going to be around to see this happen:
Across the Andes, people are preparing for the coming increase in scarcity. Mira-Salama’s World Bank project used a three-pronged approach to climate change adaptation.
First, knowledge generation: creating climate models and trying to predict the impact of glacier retreat on important crops. They also installed high-altitude ready weather monitoring equipment in the mountains of Bolivia, Peru, Ecuador, and Colombia. And finally, the Bank tried to help with “on the ground adaptation” in select Andean communities.
“We’re working with farmers [in the Santa Teresa region of Cuzco] in showcasing better irrigation practices that are more water efficient, working with them in organizing them in water associations so that they can irrigate with pre-defined schedules, working with them in finding more climate-resilient crop varieties […] and also increasing the diversity of their crops,” Mira-Salama said.
Not all communities will have World Bank help facing glacier retreat, though. As future leaders, AYP students will have to build a viable future for their communities in a glacier-parched world.
“We need to start now to make people aware of what’s going to happen, that there’s not going to be water,” Karina Jimenez Suma of Ollantaytambo said.
One idea: plant more Queyña and Chachacoma trees, which are native to the area and do not rely heavily on water.
“We can have a campaign to plant more trees in our communities, avoid wasting water, and do more sprinkle irrigation. You see very little of that [in Ollantaytambo], only a few people know about it. I think sprinkle irrigation is one of the things that can help not use much water,” Jimenez said.
Some possible solutions are more outlandish. One Chilean geologist is exploring strategies to artificially reduce glacier melting or even create new human-made glaciers.
