We are doing more than planting trees! We encourage agroforestry systems with native species in the tropical high mountains of Colombia along with easy to implement technologies for agriculture. In parallel, we are involved in topics like sustainable construction, clean energy alternatives, and water conservation. Everything making sense within the Water, Energy, Food + Forestry (WEF+F) Nexus approach. Our work is committed to the use of Free, as for Freedom, tools like GNU/Linux, OSMAnd, Gimp, QGIS, and many more!
