Projects in this category are designed around long-term carbon storage. By sequestering 10,000 tonnes of woody biomass underground in engineered, clay-lined and sealed ‘vaults’ to prevent decomposition, the projects avoid the release of embedded carbon . Agroforestry biomass that fails to grow to reach commercial values, or is simply at the end of its useful life, is a high-carbon waste product. Burial of this waste biomass secures long-term, 200 year permanence for carbon storage . Approximately 1 billion hectares of land is dedicated to agroforestry worldwide 7 . Replanting at end-of-life plantations, is an expensive operation for farmers, but represents a major opportunity to sequester carbon. The associated high value carbon credit income offers a new source of revenue in exchange for the restoration of native habitats over 15% of their land to support biodiversity . rePLANET’s pathfinder project is being designed in Costa Rica in conjunction with a major fruit company and, Nature Focus, a biomass burial specialist. It plans to bury 10,000 tonnes of biomass from under-developed gmelina and teak trees and end-of-life species including cacao, oil palm, coffee and rubber. 15% of land will be restored to natural habitats alongside replanting. If successful, this approach could be the missing answer for the funding of wildlife corridors in areas of extensive stands of agroforestry.
