🌱 MORFO has developed a solution for large-scale ecological restoration of forest ecosystems. 💌 Subscribe to our newsletter : https://morfo.substack.com/ At MORFO, we know that fighting climate change is a race against time, and we are ready to deliver on this challenge. Our drone-based reforestation solution allows us to restore deteriorated natural areas at scale around the world in just a few weeks. Our aim is to replenish and enhance the biodiversity of depopulated forests, enabling precise reforestation with indigenous plant species. We do this through science-backed innovation, in-depth R&D, and local community involvement. With a single drone, we can process up to 50 hectares of forest imagery per day and plant 180 seed pods every minute, even across steep and difficult-to-access lands. By ensuring local participation in our reforestation efforts, we are building sustainable livelihoods for the most vulnerable communities. MORFO is proudly backed by world-renowned scientific institutions such as the University of Sao Carlos UFScar, Brazilian agronomy company EMBRAPA, and the French lab trio INRAE, IRD, and CIRAD. We believe that the key to combating climate change rapidly and at scale is by harnessing science, innovation, and local participation. To join us in our efforts against climate change, please visit our website: https://www.morfo.rest Our unique technology allows us to restore deteriorated natural areas around the world in just a few weeks! Analysis, species selection, planting and monitoring, MORFO offers you the most complete, ecological and innovative solution.
