In the Peruvian Andes, Indigenous communities are reviving ancient knowledge and water practices to protect their way of life and restore vulnerable mountain ecosystems.
During the Quenua Ryami Festival, Indigenous communities in the Cusco region of Peru plant tens of thousands of quenua seedlings a day on the steep slopes of the Andes. Quenua trees are fast-growing, resistant to cold winters and can survive altitudes of up to 4,500 metres above sea level.
In addition to regulating the climate and preventing erosion, what makes these trees so invaluable is their ability to store and filter the water that feeds springs and wetlands downstream. As climate change disrupts rainfall patterns in the Andes, the trees are helping residents and ecosystems to become more resilient.
Although climate change is a relatively new challenge, Indigenous communities have long understood the importance of carefully managing water in this rugged landscape. The Incas developed an ingenious system of qochas or ponds to regulate their water supplies. Some of the ponds were designed to capture water during the short rainy season for use in dry periods. Other ponds allowed water to seep slowly through the soil, recharging aquifers and keeping vegetation for livestock green.
This system is now being revived to complement the communities’ tree-planting efforts. “It’s a beautiful practice that contributes to reforesting the headwaters of the Cusco mountains and ensures access to water for agriculture during the dry season.”
He hopes his project, which is ongoing, shows positive solutions to water issues and amplifies the ancient knowledge of Indigenous people in the fight against climate change.
