Canadian TerraFixing captures CO₂ from the air via a novel Direct Air Capture process that employs adsorption technology. It is designed to operate in cold, remote locations where extracting CO₂ from the air is easier and cheaper, and where the scalability of renewable wind power is large. The greatest challenge with DACs is likely electricity consumption. The electricity must be cheap, clean and the DACs company should not crowd out other uses of the clean electricity. Furthermore, building large amounts of clean electricity quickly is difficult due to permitting and grid connection delays. TerraFixing’s technology sidesteps much of this thanks to the possibility of deploying in remote locations where renewable energy can produce more and there is little competition for the electricity.

Justdiggit together with their main partner in Tanzania - LEAD Foundation is on a mission to regreen Africa through promoting Farmer Managed Natural Regeneration (FMNR) or Kisiki Hai method, a simple but very effective natural method to grow the remaining tree stumps into large mature trees. Trees that are part of this treecovery process grow fast because farmers select, prune, mark and protect trunks with an established root system of older trees that are still alive. Once mature, these trees contribute to more water remaining in the ground and create shade for plants to grow, increasing agricultural productivity. This project responds to the primary drivers of deforestation in The Singida region, which along with other regions in central Tanzania, has faced environmental degradation due to deforestation, unsustainable agricultural practices, and climate change. This has led to reduced biodiversity, soil erosion, and declining agricultural productivity, negatively impacting the livelihoods of local communities.
