Around 100 people live in Llano del Triunfo, one of nine villages in Santa María Yucuhiti municipality high in Mexico’s southern Oaxaca state. In winter, such high villages suffer freezing weather, and in March and April, drought is a challenge. Espacio de Encuentro de las Culturas Originarias has helped build more than 900 20,000-liter concrete rainwater tanks that collect more than 18 million liters a year. Communities are also adopting fog catchers and an irrigation system of water canals and earthen platforms based on techniques developed in Andean Peru and Bolivia to grow potatoes and quinoa. EECO is installing biofilters to treat grey water. Ecological dry toilets also help save water. More than 1,000 energy-saving stoves are in use and EECO estimates they save nearly 2,000 tons of firewood and reduce emissions by some 840,000 tons each year.
