Farmers in the Andean plateau of Puno, straddling Peru and Bolivia, are using an ancient agricultural technique known as the waru-waru system to mitigate the impacts of climate change. This method involves creating large circular patterns in fields to protect potato and quinoa crops from climate-related issues like frequent rains, floods, droughts, and frosts. The system creates a microclimate by absorbing heat during the day and radiating it back at night, and includes an intelligent drainage system to prevent monsoon flooding.
