The Gap Report sets a 2050 target of six-gigatons annual land-based CDR. Our proposed agroforestry project will convert thirty-five-million acres of rangeland in the American Great Plains to silvopasture, combining growing trees and raising livestock. Employing agroforestry interests 61% of Great Plaints farmers/ranchers recently surveyed. The Project plans to annually collect + six-gigatons CO2 equiv. of fallen leaves and store the stable carbon-rich biomass underground for centuries. The purpose of this paper is to describe the framework for formation of a global partnership at the local, regional, and international levels to coordinate public and private financing mechanisms, implement, and operate a large-scale CDR Project that will meaningfully impact the global effort to mitigate climate change.展开更多
